Slight shift in stills after fade in and fade out? Ever seen this? at DVinfo.net

Howdy..

I'm editing on a MacPro, Quadr4000, CS5.5, OS 10.6.8.

Exporting a project as ProRes 720p MRQ.

I notice when dissolving in or out on a still, there is a slight shift in the graphic as it dissolves in (ie. during the cross dissolve) and after it's fully in (ie. after the cross dissolve has finished). This isn't apparent on the timeline or when I playback the video in Premiere, but is there after I export. It's just a slight, 1pixel movement of the graphic that is barely noticeable by annoying nonetheless..

Any ideas as to what could be causing this? Greatly appreciated!

Best,

Ben

Is it only on dissolves or on any other effect as well?

What are the settings of your project, and what is the framerate of the source material?

Sometimes when using interlaced footage there might be a disconnect between deinterlacing of footage without effects and with effect (a bug in my opinion).

Consider adding transparent video clip on the topmost layer of the whole movie and reexporting.

Howdy...

I solved the issue by turning off GPU acceleration for the project. There must be something bad that happens when effects are run through the GPU... Turning off GPU for MPE and then re-exporting resulted in clean dissolves with no pixel shift at the end...

Hope this helps others...
