Hard ffmpeg compression

[alexarje]

Looks like the current settings for the ffmpeg compression of .MP4 files is a bit "hard". You can also see it in that the converted .AVI file is very small. I often use this setting in shell scripts:

ffmpeg -i "$i" -c:v mjpeg -q:v 3 "$name_conv.avi";

We may also export the audio at this step:

ffmpeg -i "$i" -acodec pcm_s16le "$name_conv.wav";

so that it is possible to do audio analysis on the files as well.

For some reason your example (first code line in your comment) is still to hard, although -q:v is supposed to do the trick... Will investigate this closer.

Works now, must have forgot to reset the kernel yesterday.

Your first example is now adopted in convert_to_avi(filename) and the second one in extract_wav(filename) in _utils.py
