For the record, I don't think ProRes is strictly lossless. But yes,
it's always a good idea to create a digital master from which you can
strike compressed copies. I always master using a truly lossless
codec, such as Quicktime Animation at 100% quality. That preserves
the RGB color space and 4:4:4 color sampling, whereas most codecs
will convert to YCbCr and subsample the color channels. The downside
is that file sizes get very large... 20 GB for a three minute film at 1080p24!

More and more people are asking for h264 nowadays - the Good Enough
attitude which is fine for most of my work. From Premiere / Adobe
Media Encoder I use the Vimeo hd 720p30 setting which is what I
mostly shoot in. Looked amazing on the big Vancouver Int'l Film
Centre screen last week. There's 1080i and p also I think.
Unfortunately, the projection booth is as varied as the edit suite
these days, so you might want to make a ProRes or other lossless
master and use that to produce versions as the need arises. Pumping
out overnight-encodings of various kinds is what computers are for,
after all... :-) http://www.flickharrison.com > On Dec 8, 2013, at

Unfortunately, the Apple ProRes encoder is not available for
Windows. There is a workaround involving ffmpeg, but it's a pain.
You have to render your clip to a lossless format such as QT
Animation, then convert using ffmpeg. This is a command line app,
but there is a front end gui available. > >

SIGGRAPH requires it, but they're really technocratic. > > Depending
on your image content, you might be OK with h.264 at high bandwidth

may be an acceptable fallback position. > > Aaron > > > > > > At
