I'm using Premiere Pro CS5, to complete a 2400*600 triplhead2go composition. I set it up Desktop, 2400*600, square pixels, 25fps & previews at the same res. All of the source clips are from After Effects (800*600, square pixels, uncompressed avi) and I want to put three 4:3 clips next to each other.
This worked perfectly when I tested it in AE, but I'm wanting to edit in Premiere. I import the clips, set the positions (X=400, 1200 and 2000) but as soon as I hit enter to render the footage, the vertical height is squished to about a third of the actual clip size. If I scale the clips to 101% or any other, exactly the same scaling problem happens when I render the timeline.
When I try to export to test if the same thing happens, I can't set an output resolution of more than 1920. I'm not sure what I've done wrong! The clips seem definitely ok, it works in AE & they play at the correct res in multiple players so I can only assume something's wrong in my Premiere settings. Is there a workaround or something I should change when setting up the project?
Any help is enormously appreciated as I've reached a dead end.
You need to try a different codec on output. Most have rules on pixel dimensions
Thanks Stephen. That was for an uncompressed avi too though, so I'm not quite sure what the deal was!
I've finally managed to sort it out now - the issue was that my computer couldn't handle the previews at that resolution for some reason. http://help.adobe.com/en_US/premierepro/cs/using/WS53d845b1b545aceaa625a7d1260ffe2746-8000 .html . When I halved the preview settings to 1200*300, that was fine and Premiere could handle it without rescaling. Big relief!
