Is it poss to render the 1280 x 720 file to an Avi of the same output size?
That would depend on the capabilities of the Topaz software. Having never used it, I can't answer this question myself.
Is it poss to render the 1280 x 720 file to an Avi of the same output size? - Premiere changes it back to 720 x 576 when I export to Avi
No. MS DV AVI is 720 x 576. You need to use AVI uncompressed or Lagarith or similar to export to 1280 x 720 AVI, but be aware of the space requirements.
Where would I find Avi uncompressed or Lagarith within premiere? I have plenty of Hard drive space for large files
I can,t afford to keep waiting while the project re -encodes to an Mp4 10secs takes about an hour
Will an uncompressed Avi still keep the quality Topaz has produced, Encoding to H264 seems to retain it but takes ages.
Where would I find Avi uncompressed or Lagarith within premiere?
You wouldn't. You do this in Topaz before you get to Premiere.
Thanks for the replys
Jim - Topaz enhance is a set of AE filters for premiere pro cs3 so everything is taking place within Premiere.
Based on this can I encode with a lossless codec to speed up the workflow?
Got it now.
Rather than exporting every clip as an HD version for later editing, wouldn't it make more sense to edit the SD clips and then uprez the output?
Yes - your right jim - I am just playing with it at the moment
