Does video card slow burn speed?

    I have a HP m7560n, 4200 with AMD dual core processor. 2 gig memory and 350 meg hard drive. It has an on board Nvidia geforce 6159 LE. It may be my imagination but it seems to take an unusually long tome to render a video file. Probably 45 minutes for a 8 gig file.
    Does the video card play any role in the speed of rendering?

    No the video card has nothing to do with it. 45 minutes to encode an 8 gig file does not sound bad at all.

    I agree that time sounds about right

    the bottom line is does it work, 45 min for 8 gigs at 2.4x would be about right

    Well, I stand corrected. I am using ULead Studio 11 to render an 8 gig file to my hard drive, so I can use Imageburn later to burn it to a disk. I am on my third hour at 74% completion. The only thing that I changed was to have it normalize the audio. Could that effect the time that much?

    Yes, depending on how many and what type of modifications made to the video/audio and how different the source format is from the output format can make a big difference in processing time. I've found that one of the most costly is to apply a sharpening filter. Normalizing te audio would take a bit of extra time but probably just a few minutes if no other audio processing is occuring but you might be going to different bitrates, different format, lots of other factors.

    I always think of the video as 24 or 30 "pictures" per second and just converting each picture to a different format, different bit-content, different dimension, takes time. Now add several adjustments (color, sharpness, brightness, etc.) to each picture and that really adds time because the program has to make all these changes to every single picture in the video and there are tens of thousands of pictures in the average video, as much as 150,000-250,000 frames typically in a long video.

    So if you do a lot of video one soon learns that that's a job for a second system; set it and forget it; I've had projects on similar rigs as yours take 3 days to render all the complicated changes I set it to do, and for only about a 5 gig final product too so you are well within very normal parameters.

    If you want quick go from DV-avi to DV-avi with just a few minimal changes to the video. That might only take 10 or 20 minutes on 8 gigs but the rest is gonna take a lot more time.
