I don't really want to use the QT export function but I'm at a loss as to how to export a 4096_2160 1.9:1 aspect ratio to an HD 1920_1080 letter box. I can do this once I'm in QT Pro7 stand alone but not in Avid's custom export as much as I've tried I can't seem to find the secret sauce.
I don't use this workflow myself but I'm trying to figure out how our AEs can do this using just Avid at their workstations. All the necessary settings seem to be there and they work when I just use QT Pro7 standalone just not when it's going through an Avid custom export.
My typical workflow is to QT Ref out of Avid and use Adobe Media Encoder to make an H_264 that I then run throught MP4toQT and QT Change to add proper time code. My work system still has an old enough AME to handle QT Ref.

Why would one still use the obsolete QT export?
It's slow, and for H264 it's the worst encoder out there.
FFmpeg is WAY better, and you can use my front end to transcode from MXF to H(x) 264 while the MXF is still in the making, so it takes little (Few seconds) to no time extra.
Get my MXFtoMp4 app and toy around, the water is sweat!

If I export to H_264 4096_2160 .mov and then in QT Pro 7 use that and choose "Export" I can export and H_264 at 1920_1080 with a letterbox when I click the "Perserve Aspect Ratio by" and choose letter box. So that works when it's done in QT Pro 7 but not when Avid is exporting through QT in Avid's Custom Export.Is there just no way through custom export to get it to letterbox the 1.90 aspect ratio into a 16:9 frame in one Avid export step. I know this has always been an issue for me hence my adopting my QT Ref workflow and Adobe Media Encoder approach. Am I missing something obvious? It's like when Avid is using the QT Engine in a Custom export it doesn't access the functionality of the export features but only the save as function. I'm sure that's not exactly what's happening but that's what it feels like. Just like my exports I'm getting squeezed a bit. ;-)John Moore Barking Trout Productions Studio City, CA bigfish@...
