Absoutely uncompressed export
Hi
I am trying to export my movie as a completely uncompressed AVI file, but each time I try it still looks fairly compressed.
It was an HDV 1080i file imported from the hard drive so I thought perhaps it was because it was compressing it from HDV to SD that would account for the pixelation by default?
Otherwise are there any setting I should be paying particular attention to? I have obviously been choosing ‘compression: none’, ‘quality: best’ and ‘colours: millions of colours +’ to get the best look.
Any help, much appreciated.
Cheers,
Adam -

HDV by its very nature is approx. 25:1 compressed MPEG-2 files so anything you do to it is going to make it look worse.
I would probably drop it into an 8bit SD timeline in FCP first and export it from there, then see what that looks like. THEN do your export to AVI and see how it compares to the 8bit SD original.
Probably going to be a long render depending on how long your clip is.

Adam,
i can not tell you much about the pixelation because I do not work with AVI files, but you started with a codec that work in the YCbCr color space and you convert it in other that work in RGB. when possible try to keep in the same color space to avoid problems. Exporting in Millions+ you dont gonna get more quality than in Millions. The only difference is that Millions+ support Alpha Channel,, so you should use it only when your film have such channel.

Yes, the AVI codec called “None” is RGB I believe. Blackmagic Design makes a more suitable 4:2:2 Uncompressed AVI codec. Its a free download. But I don’t think you can use it on a Mac.
Export Apple Uncompressed Quicktime, copy it to the PC, and download Quicktime on the PC. Then, if you must, you can convert it to a Blackmagic AVI using tools on Windows.
Regardless though, the AVI/None conversion shouldn’t add pixellation. As Walter said, HDV is hevaily compressed. Low-light footage will be pixellated.
