Hi
I use this command to convert a batch of video files form from a canon
t2i, works fine for editing in Cinelerra
for i in *.MOV; do ffmpeg -i $i -y -vcodec mjpeg -qscale 1 -s 1920x1080
-pix_fmt yuvj420p -acodec copy ${i%.MOV}-mjpeg.mov; done
I also tried this
for i in *.MOV; do ffmpeg -i $i -y -vcodec dnxhd -b 145M -s 1920x1080
-r 30 -acodec copy ${i%.MOV}-DNxHD.mov; done
But I've not been able to compile Cinelerra with external ffmpeg to use
dnxhd files yet. may be in the next project...
Félix-A.
