Read the manual, read developers corner
(http://cinelerra.org/devcorner.php), browse the archive of the ML.

There is a lot of work to do before you reach to the ' mathematical
algos for the image processing theories'. But you have to get through
source code at some level to be able to develop for cinelerra.

You may start of looking at the "Hue saturation" plugin
(https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2012-January/018507.html).
Quick look at it made me think that there is a problem of scaling the
pixel value. I suspect similar problems with other plugins using

What video driver do you use? OpenGL?

All plugins have different execution path for different color models.
Also there are different execution paths for OpenGL and non-OpenGL.
The artifacts may depend on it.

If you look at upper right corner of the frame the picture from
cinelerra has visible rectangles, the picture from avidemux these
rectangles are almost invisible. This may be some more general problem
of color handling.

Another problem I remember, is Titler. This creates wrong pixel values
in float color models. Float color value range is 0..1,
titler seems to create 0..255.

[CinCV] Re: 5.1 audio, any hints?

Hello, everyone!

It's been quite a while since I don't post in the list, but I read it often. First of all, I'd like to congratulate everyone for keeping such a long term version, and I give my best wishes for the future of Cinelerra and Lumiera!

The reason I write is that loooong ago I had asked how to set  up an 5.1 audio with Cinelerra (the questions and answers go below). So, as I prepared myself to compile a CV version from scratch, I went to test my audio configuration using speaker-test, to check if everything was ok.

I used this command:

speaker-test -Dplug:surround51 -c6 -twav

Somehow, things were not ok in both my audio boards (they used to be), so I checked wires, connections, volume etc and dug a little bit on speaker-test's manual. After 5 minutes, everything got fine again, with audio coming out of all speakers. The reason I mention this is because I saw the option "-Dplug" meant the driver used.

So I opened Cinelerra and tested everything on more time, using 6 channels on the timeline. Same thing: the audio level would show the output being sent to the speakers, but the audio wouldn't come out.

The fix:
I just tested putting "plug:surround51" in the box for the ALSA driver (instead of "default" or any of the options) and it worked! The audio is coming out of all boxes now!

Very well then, problem solved and I didn't have to compile. Of course, I know people have updated the packages and the code, so I'd like to thank everyone for helping me a long time ago and for still helping everyone. I decided to post this because I am not sure this workaround was documented in the list!

cheers, everyone!

I'm trying to do a 5.1 movie here, but it seems cin is not reading alsa correctly. I tested it both on debian and ubuntu builds, and most probably it seems like it's an alsa issue (since puredata does't seem to recognize the soundblaster card with alsa, only uses oss), so I'm writing just to see if anyone has had any similar problem or has done 5.1 videos without problems. But this seems very odd, because things worked on the previous debian and alsaconf doesn't report any errors... Also, sound comes from all 6 boxes and alsamixer recognizes the card as to increase volume, etc... I feel a bit lost here, any hints?
I have same problem. Cinelerra can work only with default alsa device. Even when I put "surround40" to device string it's sends sound to default device. I think the best way to get flexible sound is jack-audio-connection-kit especially with jack's transporter support
I dug around a bit in the code, the problem is Cinelerra scans alsa devices starting at hw:0 and going up until a device can't be opened.
From that information it builds a list of alsa devices which you can select in the preferences.
When audio playback starts, Cinelerra cross-references the selected audio device with the existing audio devices so it knows which device to open, hw:1,0 for example.
If the device in the dropdown box in the preferences window doesn't exist in the list, Cinelerra selects the default alsa device.

It's an easy fix though, in audioalsa.C replace the line:

err = snd_pcm_open(&dsp_in, pcm_name, stream, open_mode);

with:

err = snd_pcm_open(&dsp_in, device->in_config->alsa_in_device, stream, open_mode);

and replace the line:

err = snd_pcm_open(&dsp_out, pcm_name, stream, open_mode);

with:

err = snd_pcm_open(&dsp_out, device->out_config->alsa_out_device, stream, open_mode);

Now it opens the alsa device with the name you enter in the dropdown box.
However, I have no idea if this will make surround sound work.

[CinCV] AV Linux 5.0.3 "Tube" Released!

Hi fellow CinCV'ers

A quick note to pass along the release of AV Linux 5.0.3 "Tube". This
version features CinelerraCV 2.2 and also features a screencast of the new
and extra features available in Cinelerra in part 2.

For those who may be interested the release announcement, changelog and
3-part screencast can be seen here:

http://www.remastersys.com/forums/index.php?topic=1975.0

Kudos and thanks to Einar, Raffa and the other contributors to CinCV 2.2,
in my experience it is the best and most stable version yet! For the
record the screencasts were edited with CinCV2.2 and the title sequences
were done with Openshot.

Best Regards, Glen MacArthur - AV Linux maintainer

[CinCV] XML Phrasing for Grading

Hi,
I am a Director cum editor for a children feature film movie. I have done 3 children movie with my dad doing script work and now we have finished editing voice over process of our 4th film entirely with Canon HDSLR as supposed to Arri Negative done previously. And this project is being editing with cinelerra and planing to do color correction with Blender. My workflow is,,

1) editing the proxy footage as usual (specifying 24fps for project setting but original is 23.97 which doesn't matter i think)
2) giving the same file name in Reel_name column for each and every shots in the resource folder (as my color correction tool blender doesn't automatically recognize the associated files of the scene and which has to be manually selected)
3) exporting EDL and importing them in blender for further color correction and others.

The problem with Cinelerra export of EDL is it gives each and every shot the same Reel name as "cin0000". But if cinelerra exported the file name in the place of REEL_NAME="cin0000" as REEL_NAME="MVI_0002.MOV" my job would be easier. Is there any tool to do this stuff? Or any XML related tool which automatically takes the file name of the shot and fill the REEL_NAME field?

Hope i am clear and my english isn't that good.

Hi there,

I'm not sure if there is a tool for it. You can, however, do a script that does exactly what you want:

1. You'd find the line of each of your movies, probably searching for "<ASSET SRC=" in your XML;
2. Then you'd retrieve the name of each movie from the lines you've found in an array;
3. Your "REEL_NAME=" information is just about 4 lines below every item you've just found, so you could use a "for" and replace each "REEL_NAME=" content (cin0000) with the names of the movies, accordingly.

I'm doing a script that has about the same logic, but for a different purpose (update JPG proxies to TIF final files in the XML) and that's how I'm doing, sort of.

Now, tell me. Could you describe exactly how you can make Blender read Cinelerra's XML? I am very interested in it. If you could describe everything that is needed (in a form I can reproduce it here), step by step, it will be most appreciated, from the point that you have a final EDL coming from Cinelerra until you reach the very final render (to go to DVDs, internet, etc).

rock on,

Click in the bar at the top that shows /home/≤username>, then you can 
edit the path and press Enter to go to that directory.
