![]() -gifflags -transdiff or +transdiff doesn't actually do anything for transparent gifs. To force the frame rate of the output file to 24 fps: ffmpeg -i input.avi -r 24 output.-gifflags +offsetting leaves additional traces (by reducing the redraw area), so it's better disabled with -gifflags 0 like I did, but that doesn't actually fix the underlying first frame disposal issue. ![]() If you want to set the width to 1920, you have to edit it to -vf scale1920:-1. The -vf scale240:-1 sets the width to 240, and the height is resized proportionally. If you want to set it to 60, you should make it -r 60. This proves that it is indeed the frame disposal that is in cause. ffmpeg -i video.mp4 -r 20 -vf scale240:-1 mygif.gif. RecordRTC: WebRTC audio/video recording yt-giffer: youtube video to gif. After 30 seconds, the audio continues, but the video has ended. The problem is that in the output file, the audio plays back at the correct rate, but the video whizzes by about 7 times too fast, so its comepletely out of sync with the audio. ffmpeg -framerate 1 -i input03d.png -r 25 output.mp4 Frames will be duplicated or dropped to match the desired output frame rate. Im having a new issue with using ffmpeg to convert CDG to x264/AVI. Example: input images at 1 fps, but make the output 25 fps. The output will look like 1 fps, but will actually be a normal frame rate, such as 25 fps. data: cpb: bitrate max/min/avg: 50 buffer size: 0 vbvdelay: -1 Clipping frame in rate conversion. Record 1080p or even 4K clips at 60fps to maintain the high quality still. So you can make ffmpeg use a different output frame rate. Editing that information allows the gif to be fixed. In my case, the input gif has only two frames. ![]() Gimp shows the second frame as being "combine".Transparent gif "slowsmoke.gif" provided in attachment, also available here: When creating a transparent gif with ffmpeg, the first frame has a wrong "Gif Disposal" value ("Do Not Dispose" instead of "Restore to Background") and thus is always overlayed on the second frame.įfmpeg -i "slowsmoke.gif" -gifflags 0 -vf " split palettegen paletteuse " "slowsmoke ffmpeg.gif" -y
