(CS4) Adobe Media Encoder changing PAR on P2 footage. Is there a workaround?

Hi all,

I'm color correcting some P2 footage in CS4 that I need to export as uncompressed .movs. However, Adobe Media Encoder seems to be forcing a change to the Pixel Aspect Ratio and I haven't figured out yet how to outsmart it. I've been digging through the Adobe and CC forms, but I didn't see an answer although I have seen other people complain about the issue without any solutions that don't involve middleware.

My Sequence Settings are:
Editing Mode: P2 1080i/1080p 60Hz DVCPROHD
Timebase: 23.976 fps
Frame Size: 1280x1080 (16:9)
Pixel Aspect Ratio: DVCPRO HD (1.5)

This puts my raw footage on the 24PA/24P timeline without having to render a single thing. However, despite the fact that both my footage and sequence have the same settings, Adobe Media Encoder only seems to want to let me export at a PAR of .909 or 1.212, depending on which Preset I customize from when I go to export. This leads to either the wrong aspect ratio, letterboxing, pillarboxing, or a combination thereof. But I don't see a way to prevent the PAR override or manually change it myself in the Media Encoder.

Is there something I'm missing? Is there a workaround that has worked for you without sacrificing quality? Any help would be greatly appreciated! The next step is AE CS3 for effects, then either back into Premiere or Final Cut for the final timeline.

Thanks,

Jen

You have to run them through Quicktime Pro ($30.). In QT Pro, go to Window>Show Movie Properties>Presentation. Check the aspect box, changing the apeture from Classic to Clean. Save.

I'm intrigued by your post. I couldn't get this to work...AME still won't interpret my footage (NTSC D1 - 720x486 - PAR of .9) correctly.

Problem is it is AVID Same as Source from and old Meridien system which apparently doesn't flag the .mov clips. Because there's no metadata that AME is picking up on.

Any other possibilities?

BTW, - *AME won't stretch footage*, REALLY? That seems like a HUGE thing left out of the software. Puts it out of the park for what I'd use @ work to transcode...Episode Pro absolutely puts it to shame.

If I import my Premiere timeline into After Effects CS4, I can export the whole thing from AE in a .mov at 1920x1080 with square pixels and it looks perfect. Is there a way to trick Premiere into doing the same thing?

Perfect except for some interlacing/artifacting. Back to square one.
