BUG! Crash on VFX1.OFX adding basic MediaFX with "Preview" preview!

RedRob-CandlelightProdctns wrote on 11/21/2022, 10:22 PM

I'm just starting my finishing work on a project after my main editor finished her MultiCam edit.

I'm trying to add Brightness and Contrast VFX to one of my 4K media, and right after the MediaFX dialog appears, Vegas Crashes with this error:

Problem Description
Application Name: VEGAS Pro
Application Version: Version 20.0 (Build 214)
Problem: Unmanaged Exception (0xc0000005)
Fault Module: C:\Program Files\VEGAS\VEGAS Pro 20.0\OFX Video Plug-Ins\Vfx1.ofx.bundle\Contents\Win64\Vfx1.ofx
Fault Address: 0x00007FFCEC79F5F0

I can add this to an event without it crashing -- I can add it to a TrackFX and it does not crash -- but adding it to any Media causes this crash. Tried with both 4K and 1080p media clips. Also tried with "Border" VFX and same crash/error. I've used these FX for countless years without issue on this computer.. grrr.

This is a repeatable problem. I created a new project, inserted a media file, right-click choose Media FX, add "Brightness and Contrast" click "OK" -- MediaFX dialog appears and then Vegas crashes.

Performance Monitor does not show my CPU, memory or either GPU utilization anywhere near max when this happens.
I downgraded my Radeon RX 470 driver to the Vegas-recommended WHQL driver (the description says "Adrenalin 22.5.1 Recommended WHQL", but after installing and rebooting, it's showing as System Version 30.0.15021.11005)
When this is happening, GPU acceleration of video processing is set to "OFF", File/IO tab showing hardware decoding taking place on "Auto" (QSV on Intel HD Graphics 630). "Enable legacy HEVC decoding" is enabled. I share this info realizing that this probably is NOT a decode issue.

To make things more curious, I enabled "GPU acceleration of video processing" so it's now using my Radeon RX 470. Different results with this, but still not correct.

Adding Brightness/Contrast to the Event still works properly
Adding Brightness/Contrast to the Media results in a "BLACK" (blank) image on the preview monitor (but does not crash)
Adding "Color Grading" to the Media works properly. Adding Brightness/Contrast to the Media AFTER the Color Grading effect in the Media FX chain and Brightness/Contrast works correctly! If I put it before the Color Grading FX, black image in the output and none of the Brightness/Contrast controls have any impact

HELP?!

Testing on my system listed in my Signature below, no crashes at the MediaFX level.

I can even adjust the Brightness/Contrast while the clip is playing.

And yes, Preview Quality is set to Preview>Full.

@RedRob-CandlelightProdctns: I have done a quick search of our crash reporting system and I have not seen this specific issue in our database.

RedRob-CandlelightProdctns wrote on 12/6/2022, 1:26 PM

Only V20, not V18!

Just tested-- this problem does *not* occur in my Vegas 18 install, only Vegas 20.

As shown here:

Curious. It's possible I haven't clicked the button to report it, since all things I've read in the past are that the crash reports don't actually submit useful info to the team.. was I mistaken?

@VEGASDerek I've gone ahead and turned off my video acceleration in Vegas so it crashed when the media FX were added to the event. I just clicked "Send" for the problem/error report when the crash dialog appeared, along with the button to "send additional info" -- 2:29pm EST

You were mistaken. Submit reports and you can even put in an email and link to a post like this in case they need more info.

RedRob-CandlelightProdctns wrote on 12/6/2022, 8:11 PM

Hey @RogerS -- are you referring to support tickets opened through the Web, and not the crash dialog which comes up when Vegas crashes? I didn't see any prompts for linked forum content or e-mail addresses when I followed the few prompts to submit my crash report.

RogerS wrote on 12/6/2022, 8:38 PM

I am referring to the blank text box in the crash dialog which comes up when Vegas crashes. You are allowed to fill it with relevant information to help developers understand the issue at hand.

@Reyfox Preview Full does not show the problem. Preview Quarter/Half does.

Only V20, not V18!

@RedRob-CandlelightProdctns Does not occur with VP19b550 either, I suspect VP19b643 has a high likelihood of being affected.

Reyfox wrote on 12/7/2022, 5:54 AM

@Former user, correct. I too get a black screen when Preview half/quarter is selected. And with Draft selected, none of the settings work.

I can't say it was introduced in VP19 build 643 because it is working on my computer.

Hi guys! Any solution found??
Exactly the same problem here, only with Vegas 20 / 214! No troubles with Vegas 12, 16, 18.
Problem appearing only when adding a Media FX and preview window set to "Preview" Half/Quarter/Auto or to "Draft". I am on a notebook using Nvidia (GTX1060).

Reyfox wrote on 1/2/2023, 3:41 PM

None that I am aware of... still the black screen here. But there has been no update yet.

RedRob-CandlelightProdctns wrote on 1/2/2023, 4:30 PM

I have not heard back from @VEGASDerek or anyone else since submitting the crash report. Hopefully being worked on for the next build?

Hmm, thanks for you replay! I hope for an update resolving some bugs....very frustrating when dealing with this kind of problems. I am a Vegas users since it was a Sonic Foundry product (good old days!) and everything was working so well :(
By the way, is Vegas working well to you guys when rendering, having the graphic card selected in the GPU acceleration of video processing, in the Preference's Video tab? To me it is crashing at a certain (random) point of the rendering process :(((. So I have to select "Off" in the GPU acceleration, in order to see the rendering complete.... Also this is really boring!

Reyfox wrote on 1/2/2023, 5:43 PM

I've never had a crash rendering with my computer. I replaced the RX480 8GB with a RX 6700XT 12GB and the performance increase was great. And still no rendering crashes.

But then, my projects are usually under 15minutes.

Rendering issues are definitely worth discussing together.. maybe start a different thread to troubleshoot that?

RedRob-CandlelightProdctns wrote on 1/2/2023, 8:55 PM

Need to remind y'all... problem occurs with both nvidia and Radeon systems AND when acceleration is disabled too.

And does not happen in older Vegas builds.

All signs point to a Vegas bug, not a video card driver problem.

Yes, thanks, I can confirm everything you are saying....
And also about the crashes during render...it's an existing problem too :(
Could be a good idea to try to solve also this problem, yes...if anybody has ideas, welcome! Maybe a new thread, as you mentioned.

@RedRob-CandlelightProdctns: I am still unable to find this issue. Please let me know what you put into the comment field so I can filter through the thousands of records to find this.

12/6 @ 2:29pm EST is when I submitted it. I don't recall if I put anything in the comment box. I can find the project and do it again if needed.

@VEGASDerek I just submitted another crash report for you. 1:57am EST 1/5/2023.

Here's the comment I put in the box before submitting:

To VegasDerek -- VEGAS CRASH when adding MediaFX and Video Preview window quality set to "Preview (Auto)". (other users report half also causes the crash)

To recreate the crash, I:
0. Disable use of Video Acceleration (close/open vegas)
0a. Set Video Preview quality to "Preview (Auto)"
1. Add a video clip to the timeline
2. Add a Media Effect to the clip (e.g. brightness/contrast)

Vegas Crashes.

If Video Acceleration (GPU) is enabld, instead of crashing I'll just get black in the output.

I too can confirm the same results on my computer spec'ed below.

@RedRob-CandlelightProdctns: I have located the error report associated with this. It appears a small (but not insignificant) number of other users have also seeing this crash. We are analyzing. It appears to definitely be a bug in the Brightness and Contrast effect. Thank you.

@VEGASDerek I'm fairly certain it affects more than just brightness/contrast.

Color Corrector -- same crash -- Just submitted another report (included "MediaFX" in comment)
Levels -- same crash -- (submitted report with similar comment)
Mirror -- does not crash, but black screen on preview

I could go on but will stop here. LMK if you need me to reproduce with other effects added to the media level too. I'm happy to help however I can.

I can confirm it affects many of the FXs, for example also the Sharpness, Color Balance, Color Curves, Glow, etc...! To me looks like almost all of them give similar problems (Crash or Black screen/vertical stripes), when preview window set to "Preview (Auto/Quarter/Half)".
Tried in 2 different computers, with different CPUs, GPUs, Ram....same results.
