You might also want to use the trim anycodings_video-processing filter instead to select an arbitrary anycodings_video-processing segment. To make the overlay stop as soon as the anycodings_video-processing triangle video stops, otherwise it anycodings_video-processing defaults to stopping when the much anycodings_video-processing longer Atlantis video ends. Here I've added another the parameter anycodings_video-processing shortest=1 to the overlay filter: overlay=shortest=1 wget įfmpeg -i STS-132_Liftoff_Space_Shuttle_Atlantis.ogv -i opengl-rotating-triangle.mp4 -filter_complex 'colorkey=0x000000:0.1: trim=start=0:end=8 overlay' -map '' out.mp4 It also just works with a video anycodings_video-processing background. Outcome preview (horrendous FPS to fit anycodings_video-processing GIF in 2MB for upload here):Īctual video output: anycodings_video-processing Ĭiro_Santilli_with_a_stone_carved_Budai_in_the_Feilai_Feng_caves_near_the_Lingyin_Temple_in_Hangzhou_in_2012.jpg
So in my example, I had a black anycodings_video-processing background, which is getting converted anycodings_video-processing into a fixed image. filter_complex 'colorkey=0x000000:0.1: overlay' \Ĭonvert to gif just for previews on this anycodings_video-processing answer: ffmpeg -i out.mp4 -r 5 -vf "scale=300:-1,split palettegen paletteuse" out.gif The video size can be anycodings_video-processing determined with ffprobe: convert Ciro_Santilli_with_a_stone_carved_Budai_in_the_Feilai_Feng_caves_near_the_Lingyin_Temple_in_Hangzhou_in_2012.jpg -resize 1024x1024! background.jpgĭo the actual conversion: ffmpeg -i background.jpg -i opengl-rotating-triangle.mp4 \ Make the image size match the video size anycodings_video-processing of 1024x1024. Great it was able to convert chroma subsampling from 4:2:2 to 4:2:0 but the profile is high.The answer at anycodings_video-processing anycodings_video-processing was correct, here's just a minimal anycodings_video-processing concrete example of that. Is it possible wth ffmpeg or any other video transcoding tool? I have a dv video with metadata as below.
