Can AviSynth output to uncompressed format?

Is there a way to have AviSynth output to an uncompressed format?

Reason I ask, is that I have trouble with some movies and the memory requirements of MCTemporalDenoise. Which is to say, I can denoise certain movies cropped to, say, 800p, but they just hang at 1080p. I have 12G memory, so that's not the issue. I can still denoise those movies going to 'low' instead of 'medium,' but on the latter the process as good as hangs, at ca. 0.01 fp/s throughput (i7 980X). Try as I might, I haven't found a way to solve this.

Anyway, my idea is to just do a 2-pass MCTemporalDenoise job, in which I first do the upper half (540p, with some overlap), and then the lower half of the movie. For that I need to output both streams in an uncompressed format, so I can use a second pass for x264, in which I concatenate the two uncompressed output streams.

Thanks.
