Xvid/Divx are output files, not meant to be edited (variations of the MPEG4 codec, often used for Internet streaming video) so, they mostly do NOT edit well (if at all) in any flavor of Premiere, even if wrapped inside an AVI container
To edit a divx/xvid file, or convert to a format that will edit in Premiere
Ok, that sounds good, but how would I Screen Capture in MP4 in the future? Bandicam doesn't seem to have that option.
Would I need to get the codec?
Editing Screen Capture is not easy... Steve Grisetti in the PrElements forum uses Camtasia for all of his online tutorials... he write the book for PrEL http://www.amazon.com/Muvipix-Guide-Premiere-Elements-version/dp/1479311200/
Some of these are for Premiere Elements, but may help with PPro

So, other than MJPEG, what other codecs work well with Premiere?
Any standardized camera format should work fine.
Good luck finding screen capture software that uses one, though. (Please post back if you find one.)
I'm just using x264 and Adobe Media Encoder.
