I encode Windows Media v9 at 960 x 540 (medium size) at about 2200 kbps and then a 1280 x 720 at about 4200 kbps. I also do an MP4 1280×720 that I call a YouTube encode and it runs at around 6000 kbps.
So far that has been the delivery and no issues. If the 1280 WMV won’t play nice they use the 960. Windows Media is the best format for Powerpoint on a PC and the MP4 can play in PPT or Keyonote on a Mac.
Some clients actually want a full 1920 x 1080 ProRes and I usually send a LT version.
Only other format is when the web person needs a specific frame size.
I have not delivered an MPEG1 or MPEG2 to a client in quite a while.
