John, I have found that in most cases .mp4 does not render intense video effects as clearly/sharply pixel-for-pixel as does .wmv on comparable settings (at least for me). With no effects, the two are basically the same, I admit.
Improvement of quality or otherwise aside, I would like to be able to render in .wmv *period*… if for no other reason than to figure out why I’m having my current issues with it now.
I will try your 1080p suggestion first, though. Thank you!
