Hey people, And how about the best lossless, compressed codec that can be used to edit? Is h.264 Intra ok for editing? I use to use DV to edit and for exporting x264 in lossless mode (w/ flac or alac as audio).
how about muxing? I see that both ffmpeg and mencoder have buggy muxers for some stream formats (at least here, they failed to mux h.264 + flac in mkv, avi, mov or mp4). I'm using yuv4mpeg pipe to create h.264 lossless output using (very fast in quad-core machines): ln -s /dev/stdin /tmp/video.y4m ; x264 --qp 0 --no-cabac --subme 1 --keyint 1 --threads auto /tmp/video.y4m -o % bye, rafael diniz Em Thursday 02 October 2008, Florian Cramer escreveu: > On Thursday, October 02 2008, 20:02 (+0200), Martin Kápostá? wrote: > > files in DV, that is OK.
