Hi, seems to be a quite difficult topic.
I am looking for a best practice to do video editing on cinelerra. I am using a Panasonic X909 that gives me AVCHD files. According to mplayer the video codec is h264 and the audio codec is ac-3. As cinelerra-cv does not read MTS files I tried to convert them by avconv -i $SFN.MTS -vcodec copy -acodec copy $DFN.mov cinelerra is reading the file but when I drag it into the timeline it starts rendering the preview frames in the timeline. During that there is a bunch of error messages on the terminal: [h264 @ 0x7f104b6c4ae0]illegal short term buffer state detected at some point cinelerra crashes: [h264 @ 0x7f104b6c4ae0]Internal error, picture buffer overflow The only workaround I found so far is using dnxhd as video codec, which is bloating up my video files and takes a lot of time to produce. Also the ac-3 audio codec is causing problems if I convert the video to dnxhd: I get error messages like: new_acodec: couldn't find codec for "AC-3" and cinelerra won't stop playback until I terminate it. So what's the best video/audio codec for cinelerra and how do I get it. I am using cinelerra-cv-2.2 from the cinelerra-ppa repos on ubuntu 12.10. The same behaviour I get using cinelerra-cv from the stable git repo from cinelerra,org Any hints?
