[Johnedel Macalino] "I always render my work using mpeg1,mpeg2 or WMV. But I only do short projects, like 1-2 minutes long. I only do video editing as a hobby and nothing professional."
MPEG-1 is a dead format. It was used long ago for low quality video. I wouldn't use it anymore.
MPEG-2 is required for DVD's. If you're making DVD's MPEG-2 is what you want to render to.
WMV is a proprietary windows only format. You can get good quality but newer MPEG4 codecs are better.
MP4 is MPEG4 which the latest high quality, high compression, low file size format which is why everyone is telling you to use it. It works equally well on Windows and Mac so it's "one codec to rule them all". ;-)
