Bad rendering

Luke-Power wrote on 4/15/2021, 7:28 AM

Vegas is putting glitches in my renders. Missing frames, choppy playback, black boxes. I am using MPEG-2 1080 for bluray, the problem seems to occur at a variety of bitrates. I updated both vegas and my graphics driver and the problem persists. Seems to be the worst when rendering some of the transitions I have used. These glitches are showing up in my burned bluray disc. Any ideas?

I just spent hundreds on a program that has more glitches than any program I have ever used. With the money I have invested I would expect either better customer service or a program that works. There is no customer service to speak of through Magix save this forum. When Sony produced Vegas and I had a problem I called Sony technicians directly and they talked me through fixing the issue. And I want to mention back then (Vegas 6) most of my issues were unfamiliarity with the software rather than technical bugs.

This is my third version of Vegas and the first version I have owned that Magix has produced. The Sony versions were flawless as far as I could tell but this Magix version 18 is a very different story.

I do not need to be told that "You should know this because this has been requested of you before only about 4 weeks ago" and "don't expect those on the forum to have to trawl through previous posts/comments to locate this information in order to help you." I have the utmost respect for all who would reply and help. Like all of us I have a busy life and don't necessarily remember what went on in a post a month ago. I do not know why I should be expected to be a Vegas forum expert and know the standard operating procedures. Just ask me for the specs you need and I will do my best.

I realize my message is harsh and what I quoted above wasn't necessarily rude, but I think I am understandably frustrated. The issue I had "about 4 weeks ago" was a Vegas program crashing issue that I have not gotten around to resolving yet. I have been rushing through a large project and simply learned to hit save every minute. I plan to get back to solving the crashing issue once I have this project done and more free time to figure it out. Now this render issue comes up when my project needs to be delivered in two days. Between the crashing and the bad rendering I am exasperated. When I purchased Vegas 18 I also purchased a new computer and between the new program and new device I expected to be good to go. In fact I ordered the (rather expensive) computer custom to conform to the Vegas 18 requirements for 4K editing (and in this project I am editing 1080 footage).

This is message is not meant to disparage any private individual on this forum. In fact, I hope that this message helps customers like myself who are also frustrated with a glitchy program and poor access to customer service. This is meant to be a helpful message to Magix. I am loyal to Vegas and want to see the program continue into the future. Magix, please get it together so I feel that I can purchase Vegas next time I need an upgrade. I will have the information requested later today as soon as I can get it. Thank you for your time.

We can't help you without any relevant info. What's your computer specs, what media are you using, what are these Fx or transitions, what are your Vegas settings and render settings?

The best way to fix Vegas to help identify replicable bugs, and with more info we can figure out the conditions that lead to the glitches. If you include relevant info in the initial post we don't have to ask or guess. It's not like we can just say "do this" and it will fix your specific issue- most of those easy problems have already been solved. Details matter.

I also wish Magix put more QA and programming resources into Vegas. At least there does seem to be a focus on performance and stability over new features in the last year or two. 18 is my 4th Magix version and a lot better than it was.

Your explanation for why more information is needed makes sense, I will have the info this afternoon. I am sure Magix gets frustrated with the volume of people who ask questions without posting enough information to solve the issue. I felt I needed to explain my frustrations as well. With as bad as my Vegas 18 experience has been I don't imagine I am the only frustrated individual. I fear it may lead to the decline in customers and eventually the program.

This is a user-to-user forum. The people you get answers from do it in their spare time.
From time to time, however, developers come in here and help out when developer knowledge is needed.

So, please, if you need really help, provide the information you've been asked for.
We are not life coaches, we just like to help others with technical issues with Vegas Pro video editing software.

Exact symptoms of your problem

Vegas is putting glitches in my Blu-ray renders. Missing frames, choppy playback, black boxes. I am using MPEG2 1080 for Blu-ray, the problem seems to occur at a variety of bitrates. I updated both Vegas and my graphics driver and the problem persists. Seems to be the worst when rendering some of the transitions I have used. These glitches are showing up in my burned Blu-ray disc. Any ideas?

UPDATE: the MPEG2 render for DVD also glitches.

RogerS wrote on 4/15/2021, 8:27 PM

Could you provide MediaInfo for these files? https://mediaarea.net/en/MediaInfo

What is your CPU model and what is your GPU model?

What are the transitions you have used?

Just for testing purposes have you attempted to render to any other format, say commonly used ones like Apple ProRes or MagixAVC? Or is this a Bluray-specific issue and other formats work fine?

Can you share a screenshot of the render settings?

I have attached screen shots with the MedaInfo for all three camera sources I used, CPU, and GPU. The transitions I am having the most trouble with are called 3D Confetti, 3D Blow Apart, and 3D Grid Explosion.

I have tried other formats, AVC, HEVC and the problem persists.

Thanks for MediaInfo, try changing view to text and copying and pasting the contents- it has important details.
Instructions here if it's not clear.

So your only installed video card is what comes with the Intel processor (iGPU)? Okay, that's fine. Looks like a great CPU.

What are those 3 transitions from- who is the maker? I'm not familiar with them.

The transitions were called new blue, they came with the vegas 18 suite. Yes it is an integrated GPU, the eventual GPU that I want to end up with has been backordered since I built the computer back in January. I will copy and paste the text this afternoon.

What issues are you having with those transitions? Could you please report those issues to support at newblueinc.com?

What happens if you turn off GPU Acceleration for those transitions? Open one of the transitions and click on "About". In the window that opens, check the "Disable GPU" box.

@Luke-Power
Which GPU driver is installed or your Intel 630? It's very important concerning your faults to use in VPro 18 the latest, you are able to see at Help/Driver Updates

I turned off the GPU acceleration for the transition and it had no improvement. I also made sure the GUP driver was up to date, no improvement. Media info for my three video sources are below.

Thanks for the Media Info- highly compressed drone and DJI footage. You're shooting 60, 60 and 120fps? The final DVD is 30fps?

To reduce variables can you try a basic render first?

Use MagixAVC with just Mainconcept (not QSV) to the frame rate you are using for DVDs. If that doesn't work right set dynamic ram preview to 0 before rendering.

See if there are glitches.

The current Vegas 18 build is 527, have you tried updating the software?

If the problems started after Windows update 20H2, I would blame it. It caused me grief.

I have experienced something similar to what you are mentioning. on Vegas 17. 5 minute file renders well with no fx or transitions but is jumpy and glitchy when I add new blue transitions or fx. Video will also render about 1 minute of the project correctly before it goes bad. I have 64gb of ram and plenty of processing power and hd space. Tried all various memory and setting solutions with no luck. I rebuilt the project in vegas 12 and it rendered with no issues.

@powerplant
If you are seriously looking for a solution, start a new thread and give as much information as possible as described above in the first answer. You can be better helped there.
Your problem may be similar, but the hardware and software environment and the media files used are certainly different.

powerplant wrote on 3/9/2023, 8:48 PM

thank you for the suggestion, but since the previous poster (Luke) had no luck with a solution, i see no reason to expect I would fare any better. As I said, I am going back to an earlier version of Vegas which may have less features but is more stable.

We don't know. He never came back after RogerS and Reyfox's suggestions. Maybe his problem was solved?

Luke was also using a later version.

Try setting dynamic ram preview to zero and see if it helps. That was greatly improved in VP19.

Is there a specific NewBlue Fx you see issues with?
