Export resolution problem at DVinfo.net

K. Tessman · August 14th, 2006, 02:19 PM

Hopefully I'm isolating the symptoms I'm seeing properly. I'm using Aspect HD with Premiere Pro 2.0 and HD100 1280x720 24p footage captured as Cineform AVI.

Things look fine in Premiere, such as this reference monitor shot:

However, when I try to export a QuickTime movie, the Adobe Media Encoder window looks like this:

(Note the decreased resolution. The Source tab shows the same thing.)

So, the resulting exported single-frame QT file at 1280x720 looks like this:

http://www.generalcoffee.com/temp/ci.../export_qt.mov

Just exporting a plain Windows bitmap frame gives me pretty much the same thing:

The only thing that seems to maintain the full resolution on export is to export as a Cineform HD AVI, so I get the following single-frame AVI:

which can then be converted using a tool like ProCoder to the desired full-resolution QT:

Any ideas on what's going on here, or is this just a limitation of the Cineform codec's integration with Premiere?

As it is not doing that with our HD100U footage using the Aspect HD 4.1, there is something else going on. Could you also upload a source AVI that causes this issue. It is acting like you have a poor de-interlacer applied. What timeline format are you running, i.e. CineForm 1280x720 23.976p progressive?

ya its deffantly has somthing to do with ur interlace settings...i havnt looked to much into it on pro 2 but in 1.5 in your export settings you can just click deinterlace and it fixes that problem...hope that helps

Close. I'll look into it some more, but it seems to be due to having "De-interlace video while scrubbing" checked in the Playback settings for the Cineform codec. It refers to it as a "preview option", but it seems to be affecting more than just preview.

Are you using the latest build of Aspect? I recall having the same issue many months ago - I cured it at the time exactly as you did.

Yeah, it's the latest build (4.1.3.61). If that is indeed the cause (as it seems to be), it would probably be a good idea for Cineform to revise the "preview" wording of the option text, or to internally wire the deinterlacing differently so that it doesn't effect exports.
