i've seen similar questions but nothing this subtle, such a slight change. also, nothing i've tried so far has proved reliable for this whereas using cinema tools has always been reliable (i'll explain below). all i need to do is change a video's framerate from 23.976fps to 24fps. cinema tools does this by simply changing something(s) in the file header so the change does not require making a new file or more than a second, even for large files. is there an ffmpeg way of doing this?

for anyone interested, i'm making dcp files from quicktime mov files. the dcp process requires 24fps material. when i make conversions of 23.976fps material and extract the audio to put it into opendcp, the dcp-making software i like, the audio always shows an incorrect length. this does not happen if i work directly from 24fps files. for that reason and, having used cinema tools in the past for these conversions (no longer available to me now), i want to simply conform all of my 23.976fps files to 24fps and do so without doubling my disk space and time consumed.

thanks very much for any answers.

ok, do you want to change the frame rate?, if you have 23.976fps to 24fps yo have to use filter video (-vf), some like this

ffmpeg -i input.mp4 -vf fps=fps=24 output.mp4

if you have another question, type first the data of the input file, typing

ffmpeg -i input.mp4

NOTE: if you work in windows or mac, check the manual for the codes, but the structure is the same.

and type your dude with this dates.
