I used ffmpeg to concatenate to videos and it got stuck and produced a huge file. Where is the mistake?
ffmpeg batch overlay Error: "Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_overlay_0"
How to use MELT or FFMPEG for layering of a video (i.e. shifting an overlay of the same video by one frame to remove flicerking from LEDs)?
