I am exporting a dpx sequence from SCRATCH, original material is 4k RED and I am exporting 2k... each frame is taking about 1 minute to process is this normal?..(hope not because I have 3991 frames to process:-)

I am on a 3ghx xeon, windows xp, connected to a fibre SAN with all material and export on... all other specifications also meet the requirements...

What about your GPU?

It should be Nvidia NVidia Quadro FX4000 (or newer) graphics adapter with a resolution of 1920x1200 or higher.

No, it is not normal... except for two things...

1) Are you processing at "Full?" That is pulling from the 4K and does take a very long time.

2) Your graphics card is about 4 years old. The 4000 is an AGP card. Even the later models of the 4000 were PCI-e, but with an AGP bridge chip. Putting SCRATCH through the AGP bus will slow things down by a factor of... well... a lot.

Have talked to the guys at assimilate (nacho, daniel etc...) and when they answered it makes sense why it takes such along time.

It has nothing to do with GPU (although it does'nt help) it is the fact that 4k is large... and lots of power needed...

see my other post... for more info....

4K is large, but it should not take a 1 minute per frame to decompress & debayer. That should at most be seconds. If you're seeing minutes per frame something is wrong somewhere.

If you're outputting to something like DPX check your drive speed as well. The end of the REDCINE log file will also show the average decoding times it took to create the image. That will tell you if this is the problem or not.

the problem seemd to have been solved, got on the same machine today and exported the same project in less than an hour... so it must have been back up on the SAN...

SO I EMPHASIS IGNORE THE FIRST POST both REDCINE and Scratch are exporting very quickly...

disc array speed plays a very big role
