Render Time Assistance

Neutron wrote on 6/18/2018, 1:29 PM

I've been using Vegas Movie Studio for quite a while and have been trying to improve render times. I have what I thought was a pretty powerful system using a Intel I7-7700K processor over clocked to 5Ghz, 16GB of DDR4 3200 memory, SSD drives in RAID0, etc.

Video clips are MP4 mostly 24fps. Render is MP4 using the AVC/AAC codec for HD 1080 24 frame rate with a variable bit rate 24,000,000 max and 12,000,000 average.

I upgraded to the I7-7700K from an I5-6600K and expected render times to drop dramatically. However, there is only about a 20% improvement in my test clip that includes transitions, etc. 10 minute clip took 12:30 to encode on the I5 and it takes a little over 10 minutes to encode on the I7.

I do not have a video card installed, and while I did enable OpenCL in the render settings, it made no difference.

Am I missing something? I'm on version 12.0 of Vegas MS, and would upgrade to the latest if I could be assured of better performance. I tried to call the Vegas support number and just got a fast busy.

Thoughts?

Neutron - why not download VMS15 for a 30 day trial and find out the answers for yourself on your system.

Sure I could, but rather than spend an hour I don't have, I thought I'd ask a forum of folks that use this product to see what their experiences were.

Problem is their experiences may be different to yours, as unlikely others have the exact same setup as you. Anyway over to you.

A 20% improvement? Just what are your expectations?

15 might be slower, might be faster. Do report back with the results of your own replicable tests on the same project.

Well, spent some time today trying out version 15. No change in render time, and it caused a 10°C higher CPU temp to boot for some reason. I confirmed the same settings and render format were used for both.

I did some further testing and it's definitely code related. I changed the render option from MainConcept AVC/AAC Internet 1920x1080 which took 10 minutes to render an 8-9 minute video to Sony AVC/MVC Internet 1920x1080 and it only took about 6:30 to render the same video which is a considerable difference.

Guess I need to play around with the render settings to find the sweet spot.

By all means, if the quality pleases you, stick with the encoder that is faster on your system.
