Split Screen: Adds the clip so that, during playback, the clip appears next to the main clip in the timeline. Picture in Picture: Adds the clip so that, during playback, the clip appears in a smaller window, superimposed on the main clip in the timeline. The audio of the main clip is still heard. There are four overlay options:Ĭutaway: Adds the clip so that, during playback, the movie “cuts away” from the main clip in the timeline and shows the cutaway clip instead. Overlays can be arranged in the same way as any other clip. In movie projects, you can add video clips and photos as overlays, which appear on top of the main clip in the timeline.

Run ffmpeg: ffmpeg -f concat -i FileList.txt -c copy "Path\NewName_joined. Now make a txt file with the video files with contents like: file 'C:\Downloads\Video\Do you want him1.flv'įile 'C:\Downloads\Video\Do you want him2.flv' Then cut with the EXACT time format: ffmpeg -i "Path\do you want him.flv" \Īnd ffmpeg -i "Path\do you want him.flv" \ Subtitle("C:\Downloads\Video\Do you want him.flv", font="Arial", size=24, text_color=$ff0000, align=3) Open the file in a media player that will frame by frame advance and play an AVISynth file with data such as: DirectShowSource(("C:\Downloads\Video\Do you want him.flv"), Pixel_Type="yuy2").Crop(0,0,-0,-0) You could try just -c copy first, but if the video sucks you'll need to re-do it. This means you need to re-encode the video, even if you want to just copy it, or risk it being choppy and out of sync. The first -ss seeks fast to (approximately) 8min0sec, and then the second -ss seeks accurately to 9min0sec, and the -t 00:01:00 takes out a 1min0sec clip.Īlso note this important point from that page: "If you use -ss with -c:v copy, the resulting bitstream might end up being choppy, not playable, or out of sync with the audio stream, since ffmpeg is forced to only use/split on i-frames." If you want to make a 1-minute clip, from 9min0sec to 10min 0sec in Video.mp4, you could do it both quickly and accurately using: ffmpeg -ss 00:08:00 -i Video.mp4 -ss 00:01:00 -t 00:01:00 -c copy VideoClip.mp4 Basically you put -ss before AND after the -i, just make sure to leave enough time before where you want to start cutting to have another key frame. The section "Fast And Accurate Seeking" on the ffmpeg seek page tells you how to get both, and I have used it, and it makes a big difference. It's really not complicated.Īs other people mentioned, putting -ss before (much faster) or after (more accurate) the -i makes a big difference. Compile a new version yourself or download a static build from their homepage. If your ffmpeg does not support -c, or -to, it is likely very outdated. So, instead of -i -ss 30 -t 10 you could also do -i -ss 30 -to 40 to achieve the same thing. You can use -to instead of -t to specify the timestamp to which you want to cut. Note that -t is an output option and always needs to be specified after -i.įor older ffmpeg versions, if you use -ss after -i, you get more accurate seeking at the expense of a slower execution altogether. The following is equivalent: ffmpeg -ss 00:00:30.0 -i input.wmv -c copy -t 00:00:10.0 output.wmv In the above command, the timestamps are in seconds ( s.msec), but timestamps can also be in HH:MM:SS.xxx format. The following would skip the first 30 seconds, and then extract the next 10 seconds to a file called output.wmv: ffmpeg -ss 30 -i input.wmv -c copy -t 10 output.wmv You can use the -ss option to specify a start timestamp, and the -t option to specify the encoding duration.
