Any one know a good way to have a small enough .avi video to the point where the quality isn't horrible and is small enough to where osu! doesn't say that I can't upload due to it exceeding the file limit?
try using ffmpeg to convert to mp4, something like 'ffmpeg -i input.avi -c:v libx264 -crf 23 -preset medium -b:a 128k output.mp4' should work. (command was generated by chatgpt but it looks perfectly fine to use)
This should convert it to a h264 mp4 file which should be compressed enough to use. (also remember to remove the audio!!!!)
