[Michael Shick] “I think the gamma bug comes into play, in this case, because my source is HDV, which uses an SD color space, but has HD dimensions.”
What do you mean by colour space exactly? Are you referring colour subsampling, bit depth, or?
[Michael Shick] “I think Quicktime, in whatever way it is hooked up with FCP, is always forcing an HD color space on my material”
Quicktime is not ‘hooked up with FCP’. FCP is QuickTime. FCP is entirely built upon QuickTime, it would not exist without it.

[Robby Huang] “so I need to change the format of my audio on an mpeg-2 file to 44100 Hz from 48000 Hz”
You’ll have to transcode/re-transcode it.
Either re-do the initial AV transcode in compressor or demux using something like MPEGStream clip, re-do the audio to 48k and re-mux, again in MPEGStream clip

Turn this setting off. Enabling it will make the file not compatible with Quicktime, it forces the profile from ‘main’ to ‘high’
Make sure that your frame size is equally divisible by 8, or ideally 16 on both axis.
This is no relation to the QT H.264 gamma issue/bug

[Michael Magallon] “MPEG2 PAL field dominance is TFF.”
With all due respect, you are wrong, for DVD it’s LFF.
There are of course MPEG-2 based PAL broadcast formats that are TFF and I assume that is why you are confused.
If you or the OP are uncertain it’s best to set this to ‘Automatic’ in compressor.

I’m sure Craig will confirm, but I seriously doubt if cleaner is capable, it’s so very much out of date (3 years since the last, very minor, update), shame on Autodesk!

[Michael Magallon] “Bottom first (CHANGE TO TOP FIELD FIRST)”
Ignore this. PAL DV is Lower (Bottom) field first
Turn of deinterlacing

Page 77 of the compressor 3 manual (there’s a pdf of it on your hard drive).
You’ll kick yourself hard when you realise how simple it is!

Why are you resizing and deinterlacing?
