@codezealot Unfortunately this is going to be a limitation of the MPEG-1 format. If you can resize the output format using ffmpeg flags in the options, you might be able to make this work. MPEG-1 is an old and not especially efficient format, but it's what jsmpeg uses, so that's why it's necessary.

Closing issue for now.
