Vegas Pro 18: Video preview & render flickers and drops frames

Matt-Silverman wrote on 2/5/2021, 2:33 PM

Hi folks,

I recently upgraded from Vegas Pro 14 to 18. I have been using 14 for years on the same machine (details below).

Right out of the gate, I am seeing heavy flickering, stuttering and frame dropping on a variety of footage types (from different cameras and frame rates). This happens during Video Preview, and if I pre-render or render a full file. It also happens whether I have GPU acceleration enabled or not.

These drops appear as full black frames, and occur randomly, but if the project is open, they stay in the same place. Meaning, if I move the cursor onto the problem area, the video preview is 100% black.

This is not a performance issue, as I've been working with the exact same file types on the exact same machine prior to upgrading to Vegas 18. I also have Vegas 13 still installed, and when I test the files there, I get zero issues.

Everything is up to date: Vegas 18 recently updated (no fix), and my GPU and Windows 10 are also up to date.

My specs:

  • CPU: i7-6700K 4.0Ghz
  • GPU: RTX 2070 Super
  • RAM: 32GB
  • Vegas Installed on SSD

I've tried a few fixes I've found through googling, with no luck (including turning off OpenCL/GL in the developer settings)

It's not a great feeling to pay hundreds of dollars to upgrade to a version that is literally unusable, compared with the previous one.

Any help is appreciated!

Hi and welcome to the forum - albeit the wrong one.

Vegas products have their own video forum - see the Important Posts at the top of the video forum here.
