Upload a video directly from your computer to Kapwing, or paste a link to a video. >Writing library : libebml v0.7.8 + libmatroska v0.8.1 >Writing application : mkvmerge v2.9.5 ('Tu es le seul') built on >16:28:30 The input file has the following characteristics: mediainfo input.mkv I used this command to convert the file: ffmpeg -i input.mkv -vcodec copy -acodec copy -absf aac_adtstoasc output.m4v Provided invalid, non monotonically increasing dts to muxer in streamĠ: -2 >= -2 av_interleaved_write_frame(): Invalid argument Press ctrl-c to stop encoding Application Stream #0.2(eng): Subtitle: / 0x0000 Output #0, ipod, to 'output.m4v': Metadata: Reached Estimating duration fromīitrate, this may be inaccurate Input #0, matroska,webm, from *** THIS PROGRAM IS DEPRECATED *** This program is only provided for compatibility and will be removed in a future release. However, the result of this is that BOTH videos freeze the first frame for the delayed duration (of 2 seconds in this case).When I try converting mkv to mp4 using ffmpeg, the following error occurs: version 0.8.3-4:0.8.3-0ubuntu0.12.04.1, Copyright (c) 2000-2012 the Libav developers built on 16:52:09 with gcc 4.6.3 Nearly all MKV files contain H264 video-tracks, which is excatly the video-codec. Only the audio-track is often converted for increased compatibility. The video is taken as-is and embedded into the resulting MP4 file without being altered. Setpts=PTS-STARTPTS+2/TB, format=yuva420p The important thing to know here is that MKV2MP4 does not alter the video-track of a MKV in any way. If you are looking for a global Freeze button, consider connecting an external momentary switch to the Remote and assign the function 'Freeze' to it. But how many Reverb and Delay effects do you want to combine Four should be sufficient. Here is what I tried based on this similar question: ffmpeg Yes, the limit is four Freeze per Effect Button. So, either hold the first frame for the duration of the delay, or have black frames for the duration of the delay. I am trying to overlay 2 videos, and one of them (the one on the "bottom"), I want to delay the start of (let's say by 2 seconds).
