Rendering issues
I am basically creating an animated webinar. The graphics are made up of PNGs of either PowerPoint slides or images that move around to illustrate what the speaker is talking about. I have everything setup the way I want, but whenever I hit enter or select render work area is screws EVERYTHING up. Basically the images become blurry, enlarge and move to the upper right. The render bar turns from red to green in the timeline.. but the results are un-usable. I can choose export media and create a movie from the un-rendered timeline, but clearly something is wrong and I would like to know why rendering the work areas causes my project to screw up – does any one have more information or somewhere I could go to further understand what is going on and why?

What are your clip properties and sequence settings? If there is a preview render setting that mismatches the frame size etc the “enter” render (preview) will react unexpectedly.
Please post the details of the media and sequence.

It will also help to provide your system specs and the version of Premiere you are using…

I am using CS4 on vista 64 with 12 gb of ram. I am using 1034×784 png images that have been exported from PowerPoint on a 1024×768 sequence with 29.97 frames per sec. When I choose Export from the file menu I can export the project just fine at 800×600 but as soon as I render in the project the images become distorted, move up and to the right and become zoomed in.

I’m sure you’ve done this but just check your sequence settings. I had a similar situation on a PAL sequence. For some unknown reason the sequence, when re-inserting into another project, had defaulted to NTSC so everything was out of kilter when I rendered the timeline. I de-rendered it, changed the setting to PAL D1 and everything was fine.
Non-rendered timelines (either NTSC or PAL) tend to look ok in preview. It’s only when you render that they appear mis-located.

Right now the Video Preview is set to DV NTSC – I thought that was what I should use… am I supposed to have it set to DV PAL? If so can you give me a little explanation as to why.. as you may be able to tell I am rather new at this and do not full understand video.
Thanks!

As I work from UK and use PAL, I merely used my situation as an example of a setting that was different to what I had thought it to be casusing similar problems to your own.
If you work in NTSC then ideally everything should be set to that format unless or until you wish to export. Then you can make whatever format you need as a deliverable.
Quick question. When you view the timeline un-previewed, does everything look normal? If you render does it then look abnormal? Forget Export for the moment.

Exactly – in preview it looks fine and dandy – if I press enter by accident it starts rendering everything and then it is all messed up (I only found this out by accident since I have not been rendering my projects since everything worked in preview and then worked when I exported).
But yeah – preview works fine, rendering zooms in and moves the image up to the right some.

Are you working in NTSC or PAL? Tell me exactly what your sequence setting says.

when i right click on the sequence and select properties it says:
editing mode: desktop
timebase: 29.97 f/s
frame size 1024×768
aspect ratio square pixels (1.0)
fields: not fields (progressive scan)
display format: 30fps dropframe timecode
audio is 48k and displayed in audio samples
under video preview it says
preview file format: MS AVI
codec DV NTSC
neither the maximum bit depth nor maximum render quality boxes are checked. -
Ok the problem is clear now we have all the info.
Your preview codec is going to force your custom frame size to the restricted size of DV Ntsc. Change the preview codec to none or uncompressed.
Let us know.
