Another way we can impact quality is to adjust the frame rate of the video using the -r option: ffmpeg-i input.webm -c:a copy -c:v vp9 -r 30 output.mkv.

mov on the end there and make a Quicktime file instead just as easily. ffmpeg -i (input file).mp4 -c:v dnxhd -b:v 290M -c:a pcm_s16le -r 60 (output).mxf That would make DNxHD with uncompressed audio in an MXF Op1a file.And the results of ffmpeg -i test.vob afterwords

When I tried -lossless 1 on a low-quality mp4, the resulting webm was 100× larger, which was not accceptable to me All you need is this: ffmpeg -i input.mp4 -lossless 1 output.webm.

The -lossless 1 option of ffmpeg's VP9 encoder enables lossless quality mode, but with a potentially enormous increase in filesize.

I found by testing that FFV1 compresses vastly better (file size = ~80% of x265) at least on some kinds of video (if best settings are chosen for both codecs) However, for lossless coding there are better codec choices.

The correct syntax to enable lossless mode for x265 encoder in ffmpeg is -x265-params lossless=1 (you need to append =1).

You can use jpegtran to perform lossless optimization on each frame which may provide significant file size savings ChangingFrameRate - FFmpe The second -r 18 tells it to record the output file at 18fps ffmpeg - framerate 30 -i input%03d.jpg -codec copy output.mkv Note that if you omit - framerate then a default of - framerate 25 will be applied to the input.

For a straight forward method using ffmpeg to change the frame rate from 20fps to 18fps without re-encoding or dropping frames try the following: ffmpeg.exe -r 18 -i inputfilespec -r 18 outputfilespec The first -r 18 tells it to read the input file at 18fps.

The output duration of the video will stay the sameĬhange the frame rate of an MP4 video with ffmpeg - Super Use Verifying frame rate changes ffmpeg can be used to change the frame rate of an existing video, such that the output frame rate is lower or higher than the input frame rate.If the video contains audio you can also slow that down without changing the pitch, but it is not a lossless conversion g-information 0 original-video.mp4 -o temp-video.mkv ffmpeg -i temp-video.mkv -c:v copy slow-video.mp4.i don't want to interpolate or drop frames. i just want to copy the frames from the mov container (it's prores, btw) to a new container that plays at the new rate. the -vf and -r options have been suggested but require a re-encode. i'm using linux and sometimes windows, btw. i haven't found, after a lot of searching, a simple way to change a 23.976fps mov file to a 24fps mov file using ffmpeg.Home Ffmpeg change frame rate lossless lossless framerate change with ffmpeg? - VideoHelp Foru
