what information do u need? the link above is not reachable. thks

Please read the link

Intel(R) Core(TM) i7-7800X CPU @ 3.50GHz   3.50 GHz

32.0 GB (31.7 GB usable)

64-bit operating system, x64-based processor

Quadro P2000

this is my computer config.

Window 10 pro ver. 20H2

Vegas pro edit version 18. (build 528)

symptoms: It is normal when nothing is imported. When a video is imported, if press play, it can't stop. It is very lagging. If two clips imported, they can't be dragged to do fade in and out transition.

That's much more informative. If you go to help/driver update in Vegas does it recommend any newer GPU drivers? If so, try downloading and manually installing them.

For general poor performance you can try resetting Vegas (hold control + shift and double-click the icon on the desktop to start. Let go when it prompts you to clear the cache). This works surprisingly often.

Beyond that can you share what kind of media this is? How to do that here.
Does it lag with anything, even say regular h.264 MP4 out of a DSLR or are you using 10-bit 4:2:2, variable framerate, or otherwise challenging footage?

I could find the driver updated. The GPU is shown as "off". where could i update the driver?

I was using trail version on lower config. computer before. it is not lagged at all. So I haven't rendered any video yet.

Find the best driver at NVIDIA's website if Vegas can't find the driver (or the GPU!)

The issue here is likely the Quadro card. Try the driver, and then reset Vegas, and hopefully Vegas will be able to use it.

I have just updated my Quadro 2000 driver. Problem is still not solved. Preview is very lagging. once it plays, it cant stop or pause at all. I need to hard shut down the program. In this way, i cant do anything for any work! pls advice what to do.

Could you please upload to this post a MediaInfo report (in ext view)on the media that you are using - https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

The first link under point 1 in the above provides a link to get MediaInfo - which is free.

Great on the driver. Did you do the reset yet?

Some media is going to lag no matter how powerful your system is, so we need details on the media (that mediainfo report Dexcon linked to instructions for) so we can know if it really is something that can be fixed or if that type of media requires proxy files to run smoothly.

Vegas pro edit version 18. (build 528)

@edward-h
Where did you buy that version?
Mine and the normal at Magix bought latest version is not build 528
Where did you buy this version?

Hi, Dexon, Do u mean uploading my problem to ur provided link?

Hi, Roger S, I did reset. it does not help.

Hi, fr0sty, I understand that. The problem is i cant even do anything at all. it is very unusual. As i said, I use Vegas on other less powerful computer. it is not lag at all.

Hi, j-v, I bought from Microsoft store. Can I update more latest version?

Thk u all.

That's interesting, VEGAS isn't on sale on the Microsoft store...

https://www.microsoft.com/en-hk/p/vegas-pro-18-edit-windows-store-edition/9mtgh2b7lttk?cid=msft_web_collection&wa=wsignin1.0&activetab=pivot:overviewtab

can Magix's people help?

It must only be on sale in non-US stores, I wasn't able to find it, sorry.

Yes, the team can help, but we might be able to help you sooner if you can provide us with the mediainfo report on that video file that keeps freezing.

I dont understand. I cant even do anything with it. So i dont have any file to upload. The problem has been said above.

Also, your GPU isn't supported by VEGAS (it's too old, doesn't meet the VEGAS min specs), that is why it is set to "off".

That card does not support hardware decoding, which is something VEGAS uses to speed up video playback. It also only has 1GB of VRAM, which isn't even enough for 1080p editing with some of VEGAS' effects. That could be a major cause of this problem. Some formats, like HEVC, do not decode well on a CPU, so if your GPU cannot help decode it, then it will struggle to play back in VEGAS.

However, you say that on other computers, it works ok... are you editing the exact same video on those other computers, or different files?

 Do u mean uploading my problem to ur provided link?

No, not at all. Go to the MediaInfo website and download and install on your computer the MediaInfo program. Then open the MediaInfo program and direct it to one of your media files that is typical of what you are using on Vegas Pro's timeline and save the report in text view (it will then be a very detailed report). Then upload that report to this post via the Upload icon in the top banner of the Comment field.

I was using another computer which is less powerful than my existing one. That computer installed Vegas program. Program runs normally. file is not the same. but doing same a application like importing media and editing.

Runs normally when editing the same files? You said you had to import video files to make it start to freeze up. Are they the same files that worked on the other computer that is less powerful?

I mean when drag the media to the timeline. when I press play button. program will keep playing. it cant even stop or pause.

after I update the Nvidia driver. The GPU is set as optimal - Nvidia corporation (Quadro 2000)

but problem still exists

I understand that part, i'm just asking if it is the same media you are dragging to the timeline on both computers, because if it is not, there is the possibility that the media on the computer that is causing you problems is corrupted, or in a format VEGAS is struggling to decode.
