LONGGGGG Compressor Encode (over 100 hours)
by Scott Shucher on Apr 16, 2009 at 10:41:57 pm

Using Compressor(3.0.5), I've made an MPEG2 (720x480) file from a 1920x1080 Pro Res422, self contained, QuickTiime file. The results were lackluster. A lot of aliasing in the downconverted file. So, I upped the detail and anti-aliasing, found under the frame controls. The good news was the SD MPEG2 file looked great. The bad news is that it took 70 hours to encode a 35 minute HD file. I let it go all 72 hours(over a long weekend), because I was curious about the results. And the results were very good.

Now I have a 39 minute HD(1920x1080 @ 29.97) self contained, Quicktime file. Compressor wants over 100 hours to encode, to make an SD MPEG2 (anamorphic) file so I can burn a decent quality DVD in DVDSP4.

Has anybody found a reasonable setting in Compressor to make an MPEG2 from an HD file, without it looking like crap, and without it taking nearly a full work week? I wouldn't mind 24 hours if it were going to look really good, but 100 hours. Ouch, Man!

That is crazy, there is no need to be doing that with a 35 minute video.

1) If you are working with 1080i make sure your m2v is set for TOP field first, yes this is what you want.

2) Make a CBR preset with a Bitrate of 7Mbps, set motion to good (means nothing for CBR) turn off frame control.

3) if you want the best encode send the timeline from FCP, it will tie up FCP and Compressor but it should not take more than 2 hours to encode.

Is your stereo PCM (uncompressed) and your DD 5.1?

Also I would highly recommend down converting the clip to standard definition *before* encoding to MPEG-2. This should look fine and you won't need to use the frame controls in Compressor- which yes will take the rest of your life to finish rendering.

Just tried a test by exporting a quicktime conversion (downconverted) directly from the timeline, then feeding that into compressor, and the results look much, much better, with a very quick encode.

Appreciate the the help.

Sure no problem- that's how always I do it too. :)
