Shouldn’t that be vsync drop? Since the
Hello all
Thank you all for the suggestions.
I tried: ffmpeg -start_number 86400 -i finalDPX_forDCP\Respire%08d.dpx

I still get a similar result without the stated drop frames. framemd5
checksum spits out 867 frames less than total frames.
Strange..

It would depend on your target format, and I don’t think ffmpeg makes any
assumptions as for defaults. the encoder might do

I transcoded from H.264 to x265 and the target is too compressed -- faces are
waxy.
I tried the general directive '-compression_level 1'. I tried '-compression_level 6'. The results
are identical (by 'identical', I mean the exact same file size and playback appearance). So the
