I have a bunch of footage shot on a Canon 7d I'd like to transcode for editing in Davinci Resolve (I'm exploring alternatives to using Resolve's proxies).
The source footage is 1920x1080 8-bit YUV 4:2:0 @ 25fps.
I'd like to use ffmpeg and either the DNxHD or DNxHR encoders but DNxHD doesn't appear to have a matching profile and errors our and DNxHR outputs 4:2:2 video (which is arguably unecessary in this case) and doubles the original file size.
ffmpeg -i "input.mov" -c:v dnxhd -profile:v dnxhr_sq -pix_fmt yuv422p -c:a pcm_s16le "output.mxf"
DNxHD (errors "maybe incorrect parameters")
ffmpeg.exe -i "input.mov" -vcodec dnxhd "input.mxf"
My questions are as follows:
- Are either DNxHD or DNxHR capable of outputing to 4:2:0? Would doing so keep file sizes down?
- Can DNxHD transcode my source? If yes, how should I ammend the above ffmpeg parameters?
