Re: [FFmpeg-user] Remove everything but a single color (range)
On Sun, 15 Mar 2020, Ted Park wrote: I think colorkey filter can still do this. Basically you want the converse of what color keying does right? It should work the same (that is the opposite) way, and you just have to invert the alpha value. I'm not quite sure what you mean by invert the alpha value. I think you mean invert the color I'm using... ie, if want to KEEP colors very close to e6e65c (I've refined the color since my first post), then the "invert" of that would be 1919A3 (at least according to an "opposite color tool" I found). So... after some experimenting... colorkey sort of works if I use the "invert" color and max similarity and blend values: colorkey=color=0x1919A3:similarity=1:blend=1 But the yellow box is pretty faint and there's still too much of the video still visible. NOTE: this ONLY works if I use ffplay, not ffmpeg (see below). try using colorkey or colorhold with higher similarity values first. colorhold does seem to work, but as Dan Bridges points out... On Sun, 15 Mar 2020, Dan Bridges wrote: Note, this filter will only make the discriminated stuff gray, not black or transparent. Perhaps someone else will be able to help. Yes... that's what I see. If I use this: colorhold=color=0xe6e65c:similarity=0.25:blend=0.5 Then the "yellow box" stays yellow and everything else becomes gray scale... like I'm watching a black and white video. But I don't want ANY video... I ONLY want the yellow box floating around the screen. Now I did find something that works (colorhold + chromakey) colorhold=color=0xe6e65c:similarity=0.25:blend=0.0,chromakey=color=black:similarity=.1 but this ONLY works if I use ffplay, so perhaps I'm not using it correctly. **IF** I use ffplay, then this does (mostly) what I want: ffplay -i test.mkv -vf "colorhold=color=0xe6e65c:similarity=0.25:blend=0.0,chromakey=color=black:similarity=.1" I ONLY see the yellow box (although it's a bit spotty), but pretty much all of the rest of the video is completely black. That's what I want. BUT, if I use ffmpeg: ffmpeg -i test.mkv -vf "colorhold=color=0xe6e65c:similarity=0.25:blend=0.0,chromakey=color=black:similarity=.1" test-highlight.mkv Then it behaves as if the chromakey filter isn't used at all. If fact, the above produces the same output (as far as I can tell) as this: ffmpeg -i test.mkv -vf "colorhold=color=0xe6e65c:similarity=0.25:blend=0.0" test-highlight.mkv How can I get the same results with ffmpeg that I see with ffplay? I have similar results using only colorkey with the inverted color. ie, using this (sort of) works: ffplay -i test.mkv -vf "colorkey=color=0x1919A3:similarity=1:blend=1" but this doesn't seem to do anything (at least visibly): ffmpeg -i test.mkv -vf "colorkey=color=0x1919A3:similarity=1:blend=1" test-highlight.mkv Here's the complete output for ffmpeg colorhold,chromakey: $ ffmpeg -i test.mkv -vf "colorhold=color=0xe6e65c:similarity=0.25:blend=0.0,chromakey=color=black:similarity=.1" test-highlight.mkv ffmpeg version N-96974-g425b6a9a2c Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9 (GCC) configuration: --enable-gpl --enable-version3 --enable-nonfree --enable-static --disable-shared --disable-debug --enable-libass --enable-libfdk-aac --enable-libfontconfig --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-openssl --enable-libbluray --enable-libcdio libavutil 56. 42.100 / 56. 42.100 libavcodec 58. 75.100 / 58. 75.100 libavformat58. 41.100 / 58. 41.100 libavdevice58. 9.103 / 58. 9.103 libavfilter 7. 77.100 / 7. 77.100 libswscale 5. 6.101 / 5. 6.101 libswresample 3. 6.100 / 3. 6.100 libpostproc55. 6.100 / 55. 6.100 Input #0, matroska,webm, from 'test.mkv': Metadata: ENCODER : Lavf58.29.100 Duration: 00:01:27.36, start: 0.00, bitrate: 2479 kb/s Stream #0:0: Video: h264 (High), yuv420p(progressive), 720x480 [SAR 32:27 DAR 16:9], 30 fps, 30 tbr, 1k tbn, 60 tbc (default) Metadata: ENCODER : Lavc58.54.100 libx264 DURATION: 00:01:27.33300 Stream #0:1: Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s (default) Metadata: ENCODER : Lavc58.54.100 ac3 DURATION: 00:01:27.35600 Stream mapping: Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264)) Stream #0:1 -> #0:1 (ac3 (native) -> vorbis (libvorbis)) Press [q] to stop, [?] for help [swscaler @ 0x2447600] No accelerated colorspace conversion found from yuv420p to argb.

By "remove" I mean covert every that is NOT the color(s) I want to black or transparent. I have a video that contains a yellowish box that moves about the screen. I want to isolate ONLY the yellowish box. Everything else should become black or transparent. Try the colorhold filter: From http://paulbourke.net/miscellaneous/ffmpeg/FFmpeg_Book.pdf The 3 parameters are: "color" is the color to be preserved, can be specified by name or by RGB values, for example "orange" can be replaced by #FFA500 "similarity" is a percentage, 0.01 means only the specified color is preserved, 1.0 means all colors are preserved. "blend" is a percentage, 0.0 makes pixels fully gray, higher values result in more preserved color ffmpeg -i input_filename -vf colorhold="FBED54":0.01:0 output_filename This produces tight colour discrimination. If too tight, increase the 2nd parameter from 0.01 until you get what you want. Note, this filter will only make the discriminated stuff gray, not black or transparent. Perhaps someone else will be able to help.

My knowledge of "colors" in general is extremely limited... let's put it > this way, I'm pretty sure RGB stands for Red Green Blue... that's about the > extent of it. So, a specific example would be very helpful. RGB does stand for red, green and blue, and the color “#FBED54” would be a base-16 representation of how much of the three primary colors make up that specific color. The three colors are represented by two hexadecimal (base-16) digits each, with the hidden radix point on the left. So in this case, it would mean Red has a value of (0.)FB, which is 15/16 + 11/256 = 98.5%, green would be 14/16+13/256=92.6% and so on. The thing is video usually uses a different scheme of representing/storing color, so using rgb values to key the subject out might not be ideal. But still, try using colorkey or colorhold with higher similarity values first.
