My last Vegas puzzle..

Jamie-Roberts wrote on 8/20/2023, 4:38 AM

I have Vegas 19 on both a laptop and a desktop. The playback on the desktop gradually became so bad I had a new system built as I have lots of editing work and needed to sort the issue out quickly.

The new desktop has an I7 12600, an Rtx3060, SSD drives and 32gig ram with Windows 10. Unfortunately video playback in Vegas on the new system is just as bad. Unusable unless I create proxies.

I work with 4k 8bit AVC video.

Interestingly on my old laptop which is like 7 years old, I have no issues playing 4k video in Vegas.

So I have a brand new, reasonably powerful desktop that Vegas is next to useless in and I have an ancient laptop where Vegas works fine. Weird.

Makes no difference if I use GPU acceleration or not.

If I edit using proxies it's OK so it suggests an issue with CPU/ram/ HDD but surely the new system specs are adequate?

I have been forced to quickly learn and start editing using Davinci Resolve where playback is no issue even with various effects etc. I know DR is more reliant on GPU than Vegas but still.

So after many years using Vegas (started with 5 or 6) without issue I'm just about forced to leave it behind.

I just don't have time to create proxies for everything so that's not a solution.

I would still like to use Vegas for a variety of tasks not to mention edit the zillion projects I've created using the software.

I don't believe upgrading to 20 or 21 is the answer either. I've tried VP20 but got rid of it because my essential Waves audio plugins cause 20 to crash.

Sorry for long post but if anyone has any suggestions on what is causing VP19 on my desktop to playback video so poorly I'm all ears!

I generally playback video using 'preview auto'

Show me how you have set the I/O and Video tab in the preferences.

Does your processor have an internal graphics chip? What options do you have in the I/O Avc tab?.

I have nvenc and uhd770. Because I have an intel with a graphics chip.

Is it possible that your 7-year-old laptop has a graphics chip, but the new PC does not?

In Preference/Options/File I/O (tab), try checking the 'Enable legacy AVC decoding'. I've had to activate this option to get better timeline performance with 4K 8bit MP4 video, so it's worth trying since you're using AVC video.

Haha mate you are a deadset legend. Cant believe the solution was so simple! Now I can playback 4k video right up to 'best full' without issue. Ive toggled the setting on and off several times to test and definitely the solution.

Interestingly the old laptop didnt have it checked but playback is still fine. Who knows!

Thanks heaps.

The difference may be the old laptop had Intel QSV doing decoding and the new one is NVIDIA NVDEC which has issues with some media in VEGAS.

Hi Roger. The old laptop is indeed using QSV decoding. The laptop has a 940MX video card but this isnt a decoding option.

@Jamie-Roberts  @Dexcon @pierre-k First of all, if dexcon' solution is OK for for you, then be happy. However, anything legacy should be avoided if possible. Looking at your new processor info, I can definitely say it has an internal graphical processor capable of using QSV. But in order to use QSV, you may have to do a few adjustments to your system:

  1. Obviously you want to enable decoding in the IO tab of Vegas preferences
  2. Make sure the IGPU (graphic unit of the processor) is not disabled in BIOS, enable it if not so
  3. This one is a tricky one, QSV may not work (or is recognised as being available) when the internal grahic unit is not physically connected to a monitor. You could use a fake HDMI plug or plug it into a second port of your monitor as your monitor is usually physically connected to your (better) external card such as your NVIDEA card.
  4. Somewhat related to point 3: make sure your internal graphic unit does not power down after a given time when not used /connected; check your BIOS and windows settings.
  5. Unrelated to QSV, but helpful is to upgrade your windows from windows 10 to windows 11; reason is better support for hybrid processors such as yours (windows 11 is better in selecting the performance cores of a hybrid processor when needed), this may help in general performance.

Thanks for this mate. I'll use this info & do some testing.
