FFmpeg Convert H264 Video to MP4 Video File in Windows 10

Today I’ll share an FFmpeg command with you through which you can convert H264 video to MP4 video.

FFmpeg Convert H264 to MP4

ffmpeg -framerate 24 -i input.264 -c copy output.mp4
  • This simply stream copies (re-muxes) the video so there is no unnecessary re-encoding occurring; therefore the quality is preserved and the whole process is quick.
  • Frame rate is by default assumed to be 25. You can change this with the -framerate input option. Typical values are 30000/100125 (default), 24000/100124, or frame rate aliases such as ntscntsc-film, or pal.
  • If you don’t know the frame rate, you can perform the conversion using your best guess as to the frame rate, then compare the running duration of the output file with the input file running duration and then calculate the actual frame rate. e.g. assume 24 fps and an actual running time of 1:00:00 (60 mins) if the resulting file has a running time of 1:02:30 (62.5 mins) then the actual frame rate is 25 fps (24 * 62.5 / 60)
