You could also use dmMediaConverter a free FFmpeg GUI. And you can do it without reencoding the video stream (depends on avi codec). Just grab the debs from here: http://dmsimpleapps.blogspot.ro/2014/04/dmmediaconverter.html

People say convert m3u to mp3 usually means convert m3u files to mp3 files though m3u is not a format but a playlist file. Quite a few player could play it at present. As far as I am concerned, winamp support it. Regarding converting m3u to mp3, if you have the m3u files, you can try a free online audio converter to get it done. I used it each time I have ...

In addition to other answers: since you want to produce a GIF file, I assume you want to display the image on a web page. If so, I would not bother converting your PNGs at all. Just google for "javascript slideshow" and use one of the millions of free scripts. Or write your own, this is really trivial. The benefits of doing it this way are: only one image ...

Use -limit memory 1GiB to limit the amount of memory convert uses. 1000s of images would create a huge GIF that most computers will struggle to display. I keep my animated GIFs below 200 images when possible. The fewer the better. If you number your images, this command will delete the odd numbered images rm *[13579].png. So here is my typical workflow ...

I could use another open format if .gif is not supported Perhaps APNG is of use to you. It's supported by some browsers, including Firefox but at the moment excluding Chrome and IE. Since it's just a PNG extension, it's very simple to convert PNGs to APNG. The apngasm tool can do that. But the format is so simple that I recently wrote an APNG assembler ...

Personally, I would just launch it on limited numbers of files instead of all at once. For example, something like this: #!/usr/bin/env bash ## Collect all png files in the files array files=( *png ) ## How many should be done at once batch=50 ## Read the array in batches of $batch for (( i=0; $i<${#files[@]}; i+=$batch )) do ## Convert this batch ...

If you have thousands of png-s, the anigif format is weird. I would do it in this way, using avconv: avconv -i "%d.png" -r 25 -c:v libx264 -crf 20 -pix_fmt yuv420p animated.mov
