On lower framerates with a lot of motion it's not amazing if you're creating a lot of frames (like going from 30 fps to 60), but for 24 to 30 conversion I've found it to be pretty decent at producing more fluid motion that has less jerkiness. How well it works depends on the material, the framerate, and how many new frames you're actually generating. Another option when going from lower fps to a higher one is using motion interpolation with the minterpolate filter. The -r option is just the most simplistic conversion it either drops or duplicates frames, depending on whether you're going to a higher or lower framerate. If you were converting to a framerate that was even you could just use -r 24, -r 30, etc.Īlso, it doesn't actually matter how you convert the framerate as long as the result is the same.
30000/1001 is just a shorter way of typing that out. 30000/1001 is actually just a division, if you put that through a calculator you'll get 29.97002997. r 30000/1001 is a way to tell FFmpeg to convert the video to the widely used framerate that is roughtly, but not quite, 29.97 fps. I know what resolution but no idea about this -r 30000/1001 value and -video_track_timescale 30k what should I set to make it even?
The resolution, frames rates and timebase of the intro/outro and main videos don't match.Ĭonvert your intro/outro like this and then concat: ffmpeg -i intro.mp4 -s hd720 -r 30000/1001 -video_track_timescale 30k -c:a copy newintro.mp4 > handler_name : ISO Media file produced by Google Inc.
I have similar problem to this guy After merge videos, the duration is too long - ffmpeg but I have no idea how to make videos same format 1 video: > Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'outputhigh.mp4': Metadata:
