Update #2 on “FOSS multimedia authoring doesn’t quite cut it”

Friday, March 5th, 2010

This post is the reply from Shri Anindya Banerji, multimedia developer to the clarifications sought by Dr Mandar Mitra. I’m posting the Shri Banerji’s clarifications verbatim.

Legend : [MM] = Mandar Mitra; [AB] = Anindya Banerji. AB’s clarifications are italicized. The text in bold-italics are from the original mail from Mr. Banerji.

===========================
Audacity (as a substitute of Audition)
===========================

> Codecs are very poor

[MM] Poor in terms of supported formats? What format were you decoding from / encoding to?

[AB] formats and standards including ASIO, VST, DirectX, and ReWire.

> MP3 cannot be edited properly

[MM] What problem did you face? Again, I have used Audacity to edit mp3 files without issues.

> Cannot be converted into MP3 properly

[MM] I usually do my editing on wav files, and use lame separately to encode to mp3. I know audacity can be set up to use lame directly.

[AB] problem regarding transparent sample rate conversions of files from a wide array of sources and deliver them in the audio format including Windows PCM (WAV), OGG, AIFF, MP3, and WMA with customizable dither settings whether converting material to 44.1kHz, 48kHz, or 96kHz for CD, video, or DVD to get great-sounding results

> Conforming process frequently crashes

[MM] What is a conforming process? I have been using Audacity for several years now, and cannot recall a crash.

> Unsafe rendering

[MM] What does unsafe rendering mean?

[AB] no convenient batch processing feature to convert large numbers of files that have different formats, sample rates, and bit depths to one common format, or to apply scripts to multiple files

crashed many times while problems regarding rendering realtime, while overlaid ( not punched ) numerous sub-takes and saving multiple audio files faster with simply specifying the file format, location, filename template, and more, and these parameters to be applied to each file in the batch synchronization between audio and video playback over projects of any length

> Too few tools to operate

[MM] What tools were you looking for that you did not find?

[AB] looking for :

- quick mix files together by dragging clips and controlling automatic crossfades with on-clip handles

- effects including Convolution Reverb, Analog Delay, Mastering tool and Tube-modeled Compressor

- looping tools

- phase analysis tools

- effects Paintbrush tool

- spot Healing Brush tool

- phase Correction tool

- adaptive Noise Reduction tool

- spectral Frequency Display tool

- lasso tool in Spectral Frequency

- delete Silence feature

> Recording in full duplex cannot done properly

[MM] What is recording in full duplex? Playback during recording? What “improper” behaviour did you observe? In any case, for archival quality recording, you want to leave the processor as lightly loaded as possible. When I feel really uptight about this, I switch to single user mode (telinit 1) and do my recording using arecord, and edit later using Audacity.

> Dubbing facility is not available

[MM] Did you mean adding an audio track to a video recording? AFAIK, Audacity does not have a video component, so yes, I agree that’s not available. But why would you use an audio editor to do dubbing? Or maybe I am misunderstanding the problem.

[AB] problems regarding,

- display video while scrub, keyframe view, and edit sound automation in it, match up audio with the action onscreen.

- editing the soundtracks for videos

- Stretch effects or dialog to fit a video clip by simply dragging the edge of the clip in Multitrack View

- synchronization between your audio and video playback over projects of any length

- editing soundtracks for video and then export the enhanced video in AVI, MPEG, DV, or WMV format

- digitally extract tracks from audio CDs to hard drive for project use

- Seeing level meters that are in use for the master track as well as for multiple input devices, and for multiple output devices

- listening audio inputs through the software, including effects applied to the input track, then modify parameters after recording, if desired

- quickly fixing recording errors by punching in corrections on-the-fly as you rerecord, Toggle the record button to punch in new take only where to replace the old one. Punch in and out as many times as you want

- altering tempo without changing pitch, or change pitch without tempo distortion

Update #1 on “FOSS multimedia authoring doesn’t quite cut it”

Friday, March 5th, 2010

First, let me thank all my friends and colleagues in the FOSS community for coming out so strongly in support to my call for help on this matter. You guys rock! :D

Yesterday evening there was a mail from Dr Mandar Mitra (of ISI, Kolkata and IOTA Board member), wherein he posted counter arguments to Shri Anindya Banerji’s (the multimedia expert whose comments on inadequacy of FOSS tools for CBT development lead to this series of posts). Dr Mitra also asked from Mr. Banerji to clarify further on his comments.

Dr Mandar Mitra’s email rebutting the claims and asking for clarifications

NOTE : The Italicized lines are Shri Banerji’s original comments

This is with reference to the problems outlined by Shri Anindya Banerjee. I have first-hand experience only with Audacity and I found the list of problems very imprecise (details below). Perhaps Shri Banerjee could further clarify what he meant?

I think your suggestion that a small CBT be prepared as a proof of concept by competent and interested persons is an excellent one. If such a CBT can
be put together, that will be the best possible refutation of complaints about the capabilities of open source tools. If it cannot be done within a reasonable time frame, then we must decide whether the CBT itself is more important for IOTA than the means by which it is created.

Mandar.

FOSS multimedia authoring doesn’t quite cut it - A view

Thursday, March 4th, 2010

SInce my posting on the topic of “Making change happen - the case of the IOTA job ad“, there has been interesting additional development.

A multimedia expert was asked to create a feasibility plan for development of the CBT using FOSS tools, and his report is as follows. I figured it would be interesting reading for a lot of people, so I’ve shared it below.

=== THE REPORT ===

I have gone through the most recommended open source software in Linux, to be used as substitutes of the commonly known graphics related software. On basis of the requirement for CBT development project, I have performed dry-run of some test cases. The results from those trials can be stated below.

GIMP (as a substitute of Photoshop)

- No option for true resembling of bi-cubic to bilinear conversion

- Many of the layer comp option cannot be found

- Antialising is poor

- Many of the color correction tools are absent

- Cannot share GIMP comp with INKSCAPE comp and UIRA comp layer wise

- Smart object facility is not available

(There are several other problems are there in GIMP, but those are not mentioned here, only some of the points very much linked with the work procedure of CBT development are mentioned here)

INKSCAPE (as a substitute of Illustrator)

- EPS quality and standard of vector is not up to standard

- Cannot share INKSCAPE comp with GIMP maintaining vector property

- INKSCAPE drawing cannot be used properly to animate with UIRA

- Vector layers cannot be managed with UIRA

- Rasterization of Vector , maintaining transparency and smooth edges cannot be done

(There are several other problems are there in INKSCAPE, but those are not mentioned here, only some of the points very much linked with the work procedure of CBT development are mentioned here)

F4L (as a substitute of Flash)

- F4L is no more

- It is now converted into UIRA with a blend of QFlash

- Both of them are not so professional

- Crashes anytime and almost every time

- Smart clip and nested movie clip system is unstable

- Symbol definition is not OK

- Action script is full of bugs

- File compatibility is not even good

- Authoring property is very bad

- Compatibility with running text in local language is very bad

(There are several other problems are there in F4L, but those are not mentioned here, only some of the points very much linked with the work procedure of CBT development are mentioned here)

KINO (as a substitute of Premiere)

- Codecs are very poor

- Conforming process frequently crashes

- Lightweight screen captured video cannot be edited properly

- Unsafe rendering

- Unwanted loss of project data in time of save and reopen

- Voice-over cannot be taken in form of dubbing

- A little bit long timeline often crashes

(There are several other problems are there in KINO, but those are not mentioned here, only some of the points very much linked with the work procedure of CBT development are mentioned here)

Audacity (as a substitute of Audition)

- Codecs are very poor

- Conforming process frequently crashes

- MP3 cannot be edited properly

- Unsafe rendering

- Cannot be converted into MP3 properly

- Too few tools to operate

- Recording in full duplex cannot done properly

- Dubbing facility is not available

(There are several other problems are there in Audacity, but those are not mentioned here, only some of the points very much linked with the work procedure of CBT development are mentioned here)

Sony’s hi-def camcorder - Handycam HDR-XR500E plays nicely with Fedora 10

Monday, December 28th, 2009

I had borrowed my friend John Bose’s expensive new toy, the Sony Handycam HDR-XR500E to record Devdas “f3ew” Bhagat’s lecture at WBSU (Barasat) on the 26th of December, 2009.

HDR-XR500E. Image Copyright Sony
The specs of the device was *nice* - 1080i, 120GB HDD, 5.1 Dolby recording etc. It was a last minute arrangement. I didn’t like this! There was no time to tinker and see if the device was compatible with Linux and Kino for post-recording stuff.

It was set for 1080HD AVCHD or Advanced Video Codec High Definition. The camcorder was easy enough to handle. Most of the controls being easily accessible via the touchscreen. After coming back home that night, I was eager to see the results. So, with some trepidation I decided to plug in the mini-USB cable (that had came with my trusty old Canon PowerShot A610) into the mini-USB slot on the side of the HDR XR-500E.

Immediately the standard tail -f /var/log/messages routine threw up the following details:

Sweet!!! Camcorder’s being correctly auto-detected with it’s 120GB HDD storage being propering mounted and being made accessible. Going by the AVCHD file / directory structure, using Dolphin, I browsed to the STREAM folder and found the video recordings from the day, present in MTS format. The files opened nicely using the VideoLAN client (vlc) on Linux, except for the some spots of interlace combing (for an example, see this link). Oh well! we *are* working with 1080i here.

Right now, I’m using Kino 1.3.3 to import the .MTS file by converting them to raw DV files needed by Kino for its own workflow. So far, FFMpeg seems to be working nicely.

Right now FFMpeg is about half way through conversion process. I’m already looking at a ~7 GB file. Let’s hope I do not run out of space! :)

Upcoming - “System Administration Reloaded” a lecture by Devdas Bhagat on Dec 26, 2009.

Thursday, December 24th, 2009

What : A lecture by Devdas (f3ew) Bhagat, who will be passing through town and was coaxed into giving this talk.

Where : Dept of Physics, West Bengal State University, Berunanpukuria, Barasat.

When : At 12:30 PM on Saturday, 26th December 2009.

Lecture Synopsis - “Most people who end up being system administrators are self taught. There is little formal theory in this field so far. System administration also involves very different sets of tasks, ranging from helpdesk issues to management reports, from wiring to software.

A very large number of people also start off with small numbers of machines to run and few issues to troubleshoot. As the number of machines grows, keeping pace with troubleshooting becomes impossible. Sysadmins spend time firefighting, and then burn out. Hiring is often very limited due to budgetary constraints or simply due to lack of available labour.

This talk deals with the constraints sysadmins work under, and how to work around them so that they aren’t as big a bottleneck. We take a look at the mindset required to do this work, and how to convince management that the solutions you are implementing are cheaper than the alternative. We also take a quick look at some of the solutions available for sysadmins to reduce their workload.”

Speaker Bio

Devdas Bhagat is just another recovering sysadmin, and is currently playing database administrator for a large domain registration system. In his copious spare time, he works with other business units at his workplace to help tune their systems, add business benchmarks and other general monitoring stuff. He has spoken at the sysadmin miniconf at LCA’09 (Linux Conference Australia) on system automation and on DNS benchmarking. He has spoken at various network operator group (SANOG) conferences on spam control, DNS, operational issues, large scale email systems, etc. He has also been a speaker on databases at FOSS.IN and it’s previous avatar, Linux-Bangalore. When not busy working with computers, he spends time in the hills trekking and photographing.

Organised by : West Bengal University of Technology in association with Kolkata Linux Users’ Group (ILUG-CAL.ORG)

An “interesting” Friday

Monday, September 1st, 2008

The friday dawned cloudy with promises of rain and the TMC brigands…. er brigades, promising to bring the city traffic to a stand-still between 4 - 5 PM. Around 10:35 AM, Susmit and Sayamindu landed up near my house and together we headed down to RCCIIT - a local govt. run engineering college with a whole bundle of equipment - 3 laptops, 1 OLPC XO, 1 AMD UMPC, 1 Intel ClassmatePC, other assorted hardware and freebie goodies like stickers and badges from Gnome and Firefox. The occasion was TechTrix ‘08 - the college’s annual Tech Fest which Susmit wrote about here.

Reached the college, the final 120 meters had to be trudged on foot as the road was all dug up, courtesy a sewage project under implementation. Dipanjan and a few others from the local RCCIIT LUG (which is called a SLUG or Students’ Linux User Group for some reason). There was a power-cut and we were late in starting off the “show”. There were about 85 - 100 students, mainly from the 1st year and a few from the 2nd and the 3rd years, as well as a few teachers. I went up first, it was more of a general introduction to Free & Open Source Software and how it pervades all aspects of computing - from super computers to embedded applications like mobile phones and everything in between. Susmit was up next and he spoke about the Fedora project and how to start using and contributing to it. Finally with time running short, Sayamindu went up with a short but lively talk about the OLPC project.

In about 2 hours time, we tried to give these young students an overall idea about FOSS - using and contributing, trying to share with them the excitement from multi-dimensional perspectives. By the time it was over, the heavens had opened up. So we sat down and finished off the packets of snacks that the organisers had arranged. We ended up discussing with our young hosts what they could do next. Around 1:45 PM, already getting late for a proposed meeting with Tamal-da, we decided to call up a taxi and leave. Dipanjan our principal host volunteered to venture out in the torrential rains and get a cab as we were anxious not to get our equipment wet.

Dipanjan disappeared for 15 minutes and then suddenly came back thoroughly drenched. He informed us that the cab was there, but then very apologetically added that we would have to cross the sewage-cum-storm water canal over a foot bridge as the taxi can’t come to this side (college side) of the canal as the roads were all dug up.

The rains had by then dropped down to a drizzle but the roads were flooded. So, we jumped across large pools of water using slippery bricks as toe-holds and hoping not to skid and to get our gear across as dry as possible. The footbridge turned out to be standard issue rickety construction made of bamboo, over a hyacinth covered water body that looked poisonous in color. We crossed it in a single file and they even charged 50p (about 1 cent) per head as “toll”, finally clambering up the slippery slopes covered with slush from what-nots and finally we got into the cab waiting there for us.

By then it was already late and the spectre of the TMC road blocks looming large and ominous we decided to cut out proposed trip to Tamal-da’s office short and headed into the China Town for some much needed food and a place to hangout for next 3 hours so that we could “ride out” the crazy road blockade enforced traffic snarls.

We decided to go to our regular joint - Kafulok. But on reaching there we found the place’s to remain closed between 4 - 6 PM (we had never come at this time of the day before)… baah!!!!! Having left our taxi, it was now left for us to trudge back through the slushy lanes overflowing with the effluents from the tanneries…. nice touch… even nicer with Sayamindu detailing an even more worse Lake Market during the monsoons… YUCK!!!! suddenly our present situations looked a lot better.

We ended up going to the Hot Wok (very imaginative name indeed ;-) . Since Susmit is a teetotaler, it was left to Sayam and me to polish off a pint of Vodka and a couple of Bloody Marys while Susmit nursed a plain water and a Virgin Mary. That the excitement was far from over was pointed out by Susmit - the label of our bottle of White Mischief vodka ;-)

label on the bottle of vodka

By 7:45 we decided that we should be able to get transport and get back home. And so we got on the 2nd cab we found and headed home without any further incidents.

Free Map India 2008 (CCU) - Day 1

Wednesday, February 27th, 2008

Yesterday when Schyuler and Mikel arrived at WBUT, Prof Thakur happened to talk about Chaos and non-linear system dynamics. His words turned prophetic today! :P

Went to the Jadavpur University guest house in the morning to pick up our guests. Turned out that Mikel wasn’t feeling too well… we arrived at WBUT. I had someone go find some ORS for Mikel, he looked close to collapsing.

With Schyuler in the driver’s seat, we started off around 10:15, with a brief 2-minute intro from Prof Thakur. Arindam called up from somewhere en-route to Kolkata in Rajdhani Express, that they would be arriving directly to WBUT from Howrah station. Oishila had managed to secure their accomodation at SN Bose centre guest house.

With Mikel feeling steadily worse, had him lay down in WBUT’s day care centre. Apparently there were no babies in there today. So our big “baby” got to lay down there. Had the doctor come in and check him out. Pronounced it a case of stomach upset.

The workshop was in full-swing with Schyuler explaining the basics and working concepts to everyone. Except for the ILUG-CAL and FSF members, the sheer hands-on format of the workshop was unfamiliar territory for most. Yet when they got to go out with the GPS recievers, most got into the groove quite well.

Some like Santanu Chatterjee, a lecturer of CSE at WBUT and his colleagues, did a wonderfully detailed job of the task at hand, as did Susmit and gang (Subhodip and Arindam)…most importantly others too picked up the thread nicely.

I stayed back at the Uni, as did Schyuler. Urbi from Kalam landed up finally, and we had a nice discussion about how community mapping could find a place in a project like Neighbourhood Diaries. It was interesting to listen to Schyuler outline the idea behind the work he is doing for UNICEF.

We spoke about Free Software localization and the Collaborative Contents Network program which I’m trying to drive since the last couple of months. Urbi expressed a strong interest in having a localized blog setup for Neighbourhood Diaries project. We are planning to sit down with Bishan (Samaddar) shortly to discuss further on this.

With everyone coming back in with their collected data, we proceeded to the lunch. Checked in on Mikel, he was sleeping. We got some “cheerey” (pounded rice flakes) for him. Just what the good doctor ordered, in case he should wake up feeling hungry. The sessions got underway, post lunch.

That where things become more interesting for me, the actual plotting of the collected data and correcting the errors, including the lack of data in some cases. In between, I managed to bug Schyuler several times with questions like accuracy of GPS readings, the atomicity and transaction control of the data upload process, the strength of the developer community and OSM community processes in place for revision control and collaboration.

Once the proxy settings for java were in place, every one played around with the data and we got the first OSM gps data for Kolkata online. By 5 PM most of the participants were ready to call it a day. Only a handful, about 7 people stayed back for over an hour discussing in details and asking questions. Mikel woke up and announced he was feeling hungry. So it was washed “cheerey” with salt, sugar and Kinley bottled water for him… he had it sitting on the Day Care Center bed :P

Since both Mikel and Schyuler were not happy with the things at Jadavpur University guesthouse, after a bit of head scratching, we hopped over to Hotel Sojourn (”Ho-tell Sujon” in local speak). We were lucky to get accommodation for the night. Both of them were happy with the room. Tomorrow of course we have to look for new lodgings for our two speakers. Ah well!

mirror.wbut.ac.in is back online

As posted yesterday, the mirror came back online around 12:15 PM IST today. I ran the rsync scripts once by hand to update the trees. Finally , the things are back online once again.

A city kid’s reaction to OLPC XO and other stories

Wednesday, December 12th, 2007

Day 2 and 3 from Bal Vividha

A small video of the reactions of a young city-based kid to the OLPC XO. The editing, subtitling and title card creation was done using Kino and Gimp. The video was shot using a Canon Powershot A610 digicam. This is my first attempt at doing something like this, so rough edges and bad technique is to be expected :P The uploaded version has loss of details, thanks to conversion and compression, it’s not *this* bad in the final edited version on my lappy.



A slightly older lad (studying in Class VII from the South Point High School) can to our stall, and played a nice game of
chess
on one of our CASTLE Labs terminals.



Among other things, Lipika Bansal from Waag Society, Nederlands came around to the stall. She was very interested in knowing what we were doing. She wanted to visit Bijra to see what we were doing. It was a lovely exchange of ideas. She shared with me details of several projects that Waag was into at present. I particularly liked the idea of the experimental Scottie

On the last day of the exhibition, Satabdi and Debamitra from AID India came over. They too wanted to go and visit the Bijra High School project site. Probably we’ll all go for a visit on Tuesday (the 11th).

Mr. Arup Chakraborty - a member of ILUG-CAL.ORG and a key person with the Kolkata efforts of Indian Assn. for Blind Persons, came down as well, along with a colleague. They are presently using Orca screen reader and are interested in getting it to work with Bengali Unicode text. They have expressed a keen interest in closely working with ILUG-CAL in setting up a training program for the visually challenged persons in using Free and Open Source Software. We all agreed to establish a base-line reference for the program within December 2007.

Bal Vividha drew to a close on Sunday, 9th December. Chandita from Comet Media Foundation, Amit from OLPC India and myself, we all sat down for a quick review. We drew up the tentative plans have a program on ICT in Education at Mumbai during the 3rd week of February, 2008.

Day 1 of Bal Vividha

Saturday, December 8th, 2007

Today we had our visitors - the kids!!! KGeography, KHangman and the huge trove of games proved to be a _H_U_G_E_ hit. Some kids even asked how to get the net connection going on the systems and how to view movie CDs. :)

The OLPC XOs which were on the first-ever public display in these parts of the world was a major hit as well. I spent quite a bit of time with Amit from the OLPC India team discussing the project’s progress in India and possible plans for West Bengal and the east. In between we went down to WBUT and had a meeting with Prof. Thakur as well.

Also had a nice chat with Lajpat, the guy who volunteered me his Ubuntu lappy yesterday. It was a good exchange of ideas. Also got Parantapa to meet with Jitendra, the lead devel for the Physics engine for the Virtual Lab authoring software from IIIT Hyderabad.

Tomorrow promises to be a busy day. In the meanwhile here are some of the pictures from the first two days.
