Rendering Time

[Jeremy_Sawatzky]

I know this is more or less the wrong forum to ask this but i need a quick answer and dvxuser is guna take a while.

This is using adobe premiere pro CS5 and media encoder for export

Ive got 8 guitar lessons im rendering at the moment. input is avchd 1080 60i footage. Meant for web streaming so around 200mb for a 20min 720p file. Im exporting both a 480p and 720p version of each lesson in h.264. lessons are very simple switching back and forth between 2 cameras 50/50. One of the video tracks in each lesson required some color correction (rgb curves)

thats just to give u an idea of whats involved with the project.

My question for u is render time. At its current speed, (im about half done rendering) it is going to take 48 hours to finish all 16 exports (remember 2 for each one lesson). this is on an i7 930 @2.8ghz. Is this normal? its an extremely long time. Oh and i am not using the gpu to help as it produces artifacts.

thanks

usually H.264 codec is heavy to encode.. all your renders are about 5 hours and 20 minutes and they ask for 48 hours.. if you were outputting 1080p I would say that's fine.. but while you're doing smaller resolutions.. this calculation is a quite long..
if you're exporting the 720p version first then the calculation might change once it starts on the 480p version, taking less time..

You could frameserve your render and encode with x264, which produces higher quality output at the same speed or the same quality at a much higher speed.
