Proxy Files

Hello there! Last week I went from movie studio platinum 12, to vegas pro 19. My god, the difference is night and day and it is beatufiul. I bought vegas from the page, so I figured it would be 22, but maybe they stopped making it in 19? Or it's the 19th version? Who knows, not the point.

In 12, it would auto matically create proxy files from 4k videos and up, I'm in shock it now creates proxy files for only above 4k, as I just got a 4K monitor 2 weeks ago 😂
To the point, the 4K files I pop in are 100-300gb each, and they cannot be edited at all without the proxy file. Lag delay is insane.
My question is, what dictates the speed in which proxy files are created? They go so entirely slow, and I'd like to know if there's anything that can be done to speed the process up, be it hardware, or software settings.

I'm about to upgrade my rig with intel 13th gen and Nvidia 4000 series coming within the next few months, but right now I have a 7900x, 1080ti, and 64gb ram. Creating these proxies it's only pulling about 35% cpu, 40% gpu, and 4.5gb ram.

Thanks in advance for any comments/help!

It's just a number. As you say it's the 19th version. It doesn't reflect the year it was introduced.

I think it's possible to change the auto proxy trigger resolution in internal preferences. Try searching here for info on it.

In 19 it can only be auto done over 4K, but you just right click the project in project media tab to make one. I'd just like to know if anyone knows what directly correlates to the performance of creating the files.

You looked in internal preferences?

I don't see that specific tab anywhere, but in the options and preference tab, there's the dozen or so sections to alter settings. The only one I see that looks like it would be of any use is the video options tab, which I've given it the ability to use 42,000 mb of ram. 42gb is far more then the 4.5 it's using. and 20 rendering threads probably doesn't, but I've given it all 20 I got. The GPU acceleration of video processing is the only other setting I see that could alter performance, but not of this, and even still it's set to GPU as it should be, but it's still hardly touching GPU creating these.

Maybe it could boil down to drive performance it's reading from, but it's reading from a 2tb M.2, and that drive in task manager is only pulling about 6% use.

That's because it's hidden. Hold down the Shift key and select Options, Internal Preferences should appear at the bottom of the menu.

It's there- I suggested searching the forum for a reason. Now that I'm back at my computer I can add to what Eric said and show you:

I'd limit dynamic ram preview to ~10% of total system ram. It has diminishing returns.

There's no way to improve proxy file creation performance. You mentioned the source file has trouble playing in Vegas due to its size. To create a proxy file it has to play it, so if that is slow due to hard drive read/write speeds, or Vegas decoder limitations, so will the proxy creation process. XDCAM files don't use the GPU for decoding or encoding (GPU limitation, not Vegas) so I wouldn't expect a GPU would have much to do here.

Ahh, there it is. If the proxy file creation is dependent upon drive performance, there's not much I can do as it's extremely large files that are already being read off of M.2 SSD.

Sucks for me, but it is what it is. Thanks buddy.

One thing you could do would be to dispense with proxy files and use a third party program to just create files that will work happily in Vegas. For example use Shutter Encoder to output regular AVC files or ProRes equivalent files. Whether they are faster in re-encoding than Vegas is in creating proxies I don't know. Files sizes will be much larger than HEVC but they should be easier to decode.
