    I don't think this is going to be a problem for Adobe. I work in an industry that has a vocal minority online that complains that they aren't going to buy our product every time we do some small...

    You'll find that the drivers and performance of Windows 7 will rival that of OS X in a professional editing environment.

    Wow. Now I feel really stupid that I haven't seen this feature for years now!

    Can we get more accurate audio timing than just snapping to frames yet? It's what keeps me from recommending Premiere Pro to everybody.

    Samples, Milliseconds, anything!

    It would be pretty disappointing if BlackMagic wasn't on board. I would imagine they're scrambling to rectify this. They may be going to announce something at NAB so they don't want to spoil all...

    Disregard this message. Gamma is correct. Google Chrome doesn't do a TV to PC levels conversion.

    They do a straight conversion for every type of source material. You as a human can look at something and say "eww thats ugly" and attempt a different method for RGB to YUV conversion.

    Blurring knocks down those details and gives you a haze filter like effect. If you're going for that effect, it will help a bit, but actually de-noising those channels individually removes those...

    If you're trying to get a high quality export out to YouTube, I find that Red footage tends to have a LOT of detail, which may not hold up to the really poor 4-5 MegaBits per second they will crunch...

    You'll want to make sure you're not doing a bilnear scale. Lancos4 method is a very sharp downscaling method if you want sharp footage.

    Gabe,

    Banding will still occur when it goes from a 4:4:4 to a 4:2:0 subsampling unless you have noise or dithering in your gradient areas. The encoder can't make your chroma suddenly not band...

    banding happens when you have a gradient in a low noise area. A properly exposed sky with a vingnette applied is a recipie for banding.

    The only way to fix it is to add noise, or a dithering...

    I've found the best results come from manipulating individual video components before sending it to the compressor. I personally scrub the cB and cR channels clean of any noise and smooth them out...

    You guys can argue over your tools, but I think your missing the point. I will always pick the tool that lets me go home at 5:00 to see my family.

    It looks like someone took the trailer that is online and ran it through twixtor to 48FPS. It will look poor because it's not the actual data recroded, just interpolated like TV sets do today.

    I'm glad that there is a competitor for DCP, and the fact that it's actually affordable means that indies can get in on the pie.

    Just because one encoder doesn't support creating 12 bit doesn't mean that the format cannot support it.

    The High 4:4:4 Profile can support up to 14 BPC color.

    It would appear that XAVC is just High 444 h.264 profile in an MXF container. I would have to take a look at an actual file to confirm though. Premiere Pro supports this TODAY.

    My compression chain is pretty complicated as I'm usually outputting files for paying clients, but without revealing the secret recipe I do this:
