Or another option is x264vfw ; it just needs to be wrapped into MP4 container, either in the commandline box or in a 2nd step

Although PP cannot decode the lossless variety, you still have great control over various settings, compression level, GOP (I frame vs. long GOP), pixel formats etc...

720x486 won't work. Crop away 6 lines. Note I added a bit about YUY2 to my last post.

If I go with your other suggestion, which value do I set, and how low do I set it?
Also, going with this option would still leave me with having to convert to RGB, which people say it loses color quality.
