Is there some way, given m2t as input on the time line to save a segment as m2t again without loss of any quality from Vegas? I tried uncompressed avi but that results in a slightly redish tone (I've imported the avi again and put "on top" of the m2t on the time line and then toggle the "mute" - the preview shows different colouring.

If I make any colour corrections, zooms, pans on the source in Vegas, what render format would be best to save to get as close to the original quality, for later import into vegas for setting the order or merging clips into a long movie?
