File size too huge vs original - Minimum bitrate limit

Hi (searched + googled before posting question)

In this world of super 4 and 8k, we work on light videos for WA distribution.

I get source material via WA, made (very few) editing in VPX, and exported size is much bigger than source.

My sources have like 200kb/s (320x240), but VPX export won't let me set anything lower than 500 kb/s:

Hi

This is a common issue met with putting videos on WA - to get video down to such a low bitrate so as to fit in the maximum file size for > approx 4 mins of video, it is necessary to use a third party converter.
