Hey everybody,

I am using ffmpeg for screen capture and loading my captures into Pitivi for easy cutting & sound tweaks.

My screen capture command is as follows, and gets me beautiful video:
ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -r 20 -s 1360x768+0+0 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y TITLE_OF_VIDEO.mkv
After splicing and adding new audio, I'd like to know some of the best setups for getting clear audio/video out as close to the native recordings' quality/resolution as possible. I'm messing with the parameters, and compression is making things ugly. How should I retain good, grain-free quality after changes in Pitivi? I intend to upload some videos on the yewtubes, and don't want recompression into their flv to make things any less clear. Perhaps Pitivi is the wrong choice in the first place? It'd be great if I could just splice and combine video, then overlay the audio tracks somehow?
