Hi,

I need to generate a Windoze compatible AVI file that will play on older media player code. This is to drive and LED sign.

I found a discussion that related to getting a render from kdenlive to work on Windows but I'm having some problems translating what works at the command line into something in the render profile.

I used the media player Apple QT (.mov) render and created a .mov file.

Then at the command line I can do this and I wind up with an .AVI that is perfect for what I need to do.

ffmpeg -i comingsoonGoldGMT.mov -vcodec msmpeg4 -vtag MP43 -acodec libmp3lame foo.avi

But if I create a custom render profile that just contains the -vcodec msmpeg4 -vtag MP43 -acodec libmp3lame bits it, of course, doesn't render a useful. File.

How would I go about effectively chaining what is being done for the .mov render to that I can produce an .avi file using the msmpeg4 codec all in one step?

I can, of course, use a script file to process the .mov file but it would be nicer to understand how to get kdenlive to do it.

Thanks,
Burt

The manual at userbase has something on this.

Thanks,

I've looked though the manual and unless I'm missing something there is some general stuff there, and an explanation of how the ffmpeg parameters map.

But the problem is that I've tried setting up to use the msmpeg4 vcodec in a manner similar to what is described in the manual. This doesn't work. I found another discussion where someone was trying to do the same thing with msmpeg4 and the suggested soltion to them was to use the codec in an AVI or ASF container file, and not the Mpeg container they were trying to use.

But that solution doesn't work either as that was what I was already doing.

That thread is here: http://www.kdenlive.org/forum/rendering-using-msmpeg4

As mentioned I can render to a .mov using the Apple rendering profile. Then I can use a shell script that applies the msmpeg4 codec to the .mov file and creates the suitable .avi file. I would just like to figure out how to do this from within the kdenlive rendering.

I think I have it figured out, and for anyone else who is having a similar issue here's what I did.

For the render profile parameters:

qscale=2 vcodec=msmpeg4 vtag=MP43 acodec=libmp3lame

The qscale=2 parameter helps to improve the quality of the render.

In the render profile I have the Extension set to avi

Note there probably are additional parameters that could be added to the acodec but in my case I don't need audio anyway for the LED sign.

The thing that I missed from the old discussion was the force Progressive setting on the render dialog needs to be set. It was Auto and would keep failing.

I need to test with a few more videos but I believe that this will work as needed.
