Using the average method, we get a grayscale image like this one: To further split the foreground (the DataMatrix code) from the white background with the red lines, let’s give a larger weight to the red channel. Here is the result. TīmeklisYou can drop 2 out of 5 frames with the shuffleframes -filter: -filter:v "shuffleframes=0 1 2 -1 -1". then I would use the setpts -filter to modify the frame timestamps to get a CFR 72p stream: -filter:v "shuffleframes=0 1 2 -1 -1,setpts=N/ (72*TB)" And finally I'd use the minterpolate -filter to blend frames. TīmeklisIf it works fine, go ahead. Realistically I doubt you'll hear much of a difference between ac3 @ 640kbps and eac3 at similar or higher bitrates. The only advantages of eac3 are support for 6.1 and 7.1, which ffmpeg can't encode and support for Atmos, which ffmpeg can't encode, so as I said I don't think therell be much, if any, difference. bottom of the pyramid products
