@RogerS  ... Unfortunately, Vegas Pro 12 doesn't have a high DPI option in Preferences - unless of course the OP made a typo and meant VP21, but the uploaded image does look like VP12.

Unfortunately, Dex is correct. VP12 isn't compatible with 4K screens. You'll have to update, or set windows to only send 1080p to that TV.

Got it, never used a 4K screen with any version of VEGAS.

I would say that for such modern hardware a newer version would take fuller advantage of it (GPU-supported decoding/encoding) as well as support such screens with high DPI modes.

how would i do that?

i will also try to dl the latest vegas i have tried to upgrade a few times and to date the updates dont open my older projects so I just stick with 12.

Your hardware should run V22. Your 13900K will have integrated graphics built in and available via MB output. connect that to your TV via HDMI. Under options,prefs,preview device select 'windows graphic card and apply. If you now go to main screen and click on 'double window' 2nd from left above preview screen your TV should echo the preview window. This connection will also enable 'Intel Quick Sync'..Other options include installing BlackMagic card eg IP4K or similar.

Maybe download a trial of V22 & test.

V22 works perfect no config necessary. Unfortunate like before it wont open my project that was created in V12

@JHendrix

Hmm....the project should be able to be imported into VPro 22. If possible, it would nice if you could provide the VEGAS team your project file so we can determine why this is not able to be opened in VPro 22.

ok how would i do that? note: as i said i have tried to upgrade a few time over recent years and that is why i did not. not sure if it was same error though since its been a while.

also, when you say import you mean Open right? I dont see a "project import" option in import only "media"

i send a link to VEGASDerek in a PM. if anyone else wants to give it a try feel free. https://drive.google.com/file/d/1-hQUXgKsafWXBfqECp2lHmEPDO7I2niX/view?usp=sharing

It opened fine for me in VEGAS Pro 22. It couldn't find your media, obviously, because it wasn't included with the project file, but the project did open.

No problems here either opening the project in Vegas Pro 22:

then the error above "the file is an unsupported format" must be referring to a media file...hummm

Just out of curiosity... it says "14.2 V22.veg." Is that "." that is after ".veg" in the filename? If so, rename it so it isn't there.

Can you share that specific project file? It has a different name than the one you posted above.

the period is just part of the error message. the file is .veg I just tried again and it starts to load files in lower right then gives error. reminds of of many similar bugs of days gone past where i had to work voodoo to open some. in addition to regular media / video. in this case the project does have a few different formats the possible suspect could be some mp4s that are youtube rips?

but all video types in project are

.mp4

.mts

.mov

.avi

If a media file was unable to open in the project, the project should still open, but just not that specific file. Can you try importing the media files themselves into VEGAS 22, and see if they will import into a new project? That will isolate if it's the media, or if it's the project file itself.
