And the last time I tried saving a video bigger than that, it wouldn't play.

If you're saving it as uncompressed, that'll happen. It's because it's completely lossless quality (highest quality possible), so it makes for a massive filesize and jittery playback unless you have a powerful PC.

I recommend you keep saving it as uncompressed in case you need to do editing and the like, and then use a third party program to encode the final copy for publishing.

I use Lagarith Lossless Video Codec to encode movies. It does a good job of compression and if you and disallow "inner prediction" which makes each frame individually decodable for much easier editing.

Forgot to add that it's free and open source.

Oops, I got the sizes confused with another on - it doesn't compress much in this mode it won't help your file size.  But you should try other codecs to find one that's suitable for your needs.

Took a large video and put it in WLMM, saved it as a wmv file instead of avi, and it played a LOT smoother.

the xvid codec is amazing but unfortunately it isn't widely supported with editing software and there are few hardware decoders out there that directly support it.

My own technique is to always render to individual, sequentially-numbered images in a folder, rather than direct to video, and use something like Virtual Dub (http://www.virtualdub.org/ ... it's free and just works) to render them to video if required.  Like Kreator I generally use Xvid for its quality but it is rare than these videos go into actual production, rather they are for distribution to the production team for comment etc. (most of my work is in a collaborative team environment).  The still images are provided to the editor who stitches them together using whatever editing software he runs, presumably After Effects or similar, so it's unusual that I would be required to provide high-quality video files.

The big advantages of this method are that you have direct access to all frames for post-render editing if required, if there's a problem with something you can re-render just those frames that are affected, if the power goes out mid-render you can easily pick up from where you were, and you can try out a bunch of different video compressors and sizes in VDub without having to re-render in Anim8or.

Codecs?
'codec' is short for 'coder/decoder'; it refers to an algorithm used to compress video data (coder) and then to unpack the data and play it back again (decoder).  it's a generic term covering DV, MPEG (in all its numerous sub-variants), WMV and XVID, and many others.

personally, i use an MPEG-2 variant, partly because it seems to be the preferred format for recent versions of Sony Vegas, and partly because it gives a good colour gamut - as compared to WMV, for example, which seems to have a reduced contrast range and tends to wash out the stronger blacks and whites.

in terms of editing programs, WLMM will do if you just want to recode/compress video clips without doing too much editing on them, but if you plan on doing any significant amount of editing then there's a lot to be said for getting something like Vegas, as it gives you a lot more options.
