![]() ![]() This command allows you to extract specific frames from a video, which are basically image files that make up the video. Output.mp4 is the output file, you can rename it as you need. 'copy' means you're using the same codec as the input file. vcodec stands for the video codec to encode the output file. i is the input file, in the above case it's a file called 'input.mp4'. Change the -segment_time to increase/decrease the amount of time per chunk as desired.Get 3-Month FREE License (Limited Time) >īefore digging into how to use FFmpeg, keep in mind the powerful command: ffmpeg -ss 00:00:05 -t 6 -i input.mp4 -vcodec copy -acodec copy output.mov. ![]() The command below will split the video into chunks that are roughly 20 minutes long. there are very-few shared pixels with the previous frame). These usually occur when the video snaps from one scene to another (e.g. Luckily, there is a better solution, where you can just tell FFmpeg that you want to split it into relatively equidistant chunks, and it will do this with no overlaps, by splitting on the nearest keyframe. Unfortunately, videos tend not to have "fade-to-black" scenes every 20 minutes, and even worse, I found that using ffmpeg -ss to break up the videos into different chunks, and then playing them back in a VLC playlist, I would end up with a little bit of overlap, making the video look like it would jump. Thus, I wanted to see if I could break the movie up into 20 minute chunks, interpolate those chunks in parallel, and then stitch those processed chunks together and perform a final 2-pass HEVC encode (which is multi-threaded). Unfortunately, the process runs on a single thread, so doing this for a 2 hour movie would take a looooong time. It's pretty amazing how well it does the job. I recently discovered how to get FFmpeg to interpolate frames in order to create amazing 60fps videos. ![]()
