Okay, that's good to know!

That's what I thought, although I suppose Smoothlevels is a little slower.

Oh, I hadn't heard about this codec, it seems efficient! Also good that there is some recent development in the field of lossless codec, all the others seem to not have had active development in a long time.
As a sidenote, it would be good have a Wikipedia article about the Ut codec, that's where I was looking for info on different lossless codecs.

There are ways to get the raw YV12 out of a Fraps video but the major problem is Fraps uses some weird custom coefficients to convert between YUV and RGB, giving slightly wrong colors if you do not use the Fraps decoder which always decodes to RGB.
Capturing in RGB avoids all that.
Just another reason to try and avoid Fraps. RGB capturing seems ok though, but I think most systems and especially HDDs can't handle it at 1080p.

Edit: Doing some checkup on Lagarith, it does seem that the codec has had development not too long ago, back in last december. Reading the changelog, there seems to have been major optimizations, such as multithreading and SSE2. So it might not be so slow after all? Anyway, probably best to do some testing and compare both Lagarith and Ut.
