The question is if I could always use this idea to produce html5 compatible video and if this method will actually speed up video conversion. I wonder if I could use ffprobe to test if input video is "H264" and "aac" and if so then maybe I could just copy video/audio into output without modifications.įfprobe -c:v libx264 -c:a copy ouput.mp4 I use ffmpeg for conversion and it takes a lot of time. Since your MOV and MP4 files probably contain the same video and audio formats you can encode the MP4 and make the MOV by re-muxing (with stream copy mode) instead of re-encoding: ffmpeg -i input.mp4 -codec copy output.mov WMV. How do I speed up a video using ffmpeg Speeding up/slowing down video This can be done via two methods: using the setpts video filter (which requires re-encoding) or by erasing the timestamps by exporting the video to a raw bitstream format and muxing to a container while creating new timestamps. My understanding is that my output should be. If your ffmpeg is outdated then youll need to add -strict experimental to use -c:a aac.
