November 23, 2009 at 3:14 pm in reply to: Looking for best export settings for downloading from the web[Anthony Medel] “That’s where I get confused. For the mov files, I’m exporting as h.264 with a frame rate of 25 fps and bitrate at 2500 for the high quality version. For the wmv high quality, I have it set at a variable bitrate of 2500 and 29.97”
Why does one output have a frame rate of 25fps and the other of 29.97 – is the source from USA or Europe?
You need to get yourself a dedicated compression/transcoding application, like compressor, episode etc etc, if you have FCP, then you probably already have compressor.
Start playing with the presets, it won’t do WMV for you – for that you need Episode.

Yes
[Andrew Saliga] “Turning off “Auto Key Frame on Scene Change” made the greatest difference”
Interesting and expected, Sorenson seem to have a bad implementation of this technique, they consider scene change only by the difference between a selection of frame difference thresholds and little else. Obviously best left off!
[Andrew Saliga] “In H.264s in Squeeze I have the options of Apple, Main Concept, Sorenson, and also a Sorenson MPEG4 Pro. I’ve heard Dicas’ implementation is good. I know you’re a Episode guy, buy do you have any insight/thoughts on the Sorenson MPEG4 Pro? “
I don’t know what MPEG-4 Pro is but it sounds like MPEG-4 SP with some tweaks rather than H.264. Of the choice I’d pick MainConcept, I have deep experience of it and it can be great (although maybe not up to Dicas level with difficult situations; complex source at ultra low bit rates, for example
[Andrew Saliga] “I know you’re a Episode guy, buy do you have any insight/thoughts on the Sorenson MPEG4 Pro? “
I’m not an Episode guy, but I do find it the best all-round transcoder on the Mac. For MPEG-4 and H.264, Handbrake and ffmpegX are the best on the Mac.
FWIW, the best transcoder on the market is made by Rhozet.

November 20, 2009 at 8:12 pm in reply to: compressor: brightness and saturation adjustmentsThere are some Gamma issues when encoding to the Quicktime H.264 CODEC, however trying to correct for any kind of onward colour correct those platforms maybe doing is going to be a hit and miss affair.
I’m of the rule of thumb that if it looks correct on my correctly calibrated setup then it’s good to go. If people want to mess with it after that, then that’s their lookout.
Sorry, but that’s just my arrogance!

I’d go with the ProRes Codec.

What were the DVD’s MPEG-2’s encoded at?

Try increasing that to be 10x your target frame rate and also try it without Auto on scene changes.
P.s. – Squeeze uses the Main Concept Codec, Episode uses the Dicas H.264 codec which is better than either the Apple one or MainConcept’s

[Joshua Carlon] ” Is there a setting I’m missing? Average bitrate is 3.3. “
Difficult to tell, you haven’t provided any or your settings other than bit rate!
Please provide a detailed run down of exactly what settings you are using.
