Anybody got anything on this? :(

Which build of VEGAS 19 are you using? Can find under Help>About

Build 648

Hmm... any chance you could share a sample clip that we can try, to see if we can reproduce the error on another machine? Via dropbox or google drive, or a similar file-share service?

sure thing no problem, here is one: https://www.dropbox.com/s/mo0bc1jg6sl2k6s/810A6534.MP4?dl=0

That file gives no problem at my laptop from signature, all settings default.

What is exactly your hardware and driverversions?

What is exactly your hardware and driverversions?

AMD 6950XT w/ 22.11.2 firmware (Driver Version
22.20.29.10-221130a-386458C-AMD-Software-Adrenalin-Edition)
Threadripper 2950X
128GB RAM

I will say this problem persisted on a previous GPU as well, that being an AMD Vega 56.

It is especially puzzling to me that it drops into the timeline in Vegas 15 and 18 no problem still, as we speak.

Does drag and drop not work only, or will importing it via file>import media not work as well?

When importing via menu that way, I get: "Warning: An error occurred while opening one or more files. The file could not be opened. Make sure the file exists and that you have access to the file/folder."

@HeavyMetal

I was able to open your sample file on the ancient system in my signature.

The Mediainfo of the sample file doesn't match the Mediainfo that you posted earlier.

I am not trying to open a single specific file, I am trying to open any file at all recorded from this R5, so didnt feel matching the exact file was particularly relevant. In any case, here is the info off that file I linked in here:

Please state your O/S version and show your installed updates.

Sure thing, here that is:
Also, Windows 10 64 bit

Quite the mystery I suppose

No trouble to me as well.

How about other MP4 ? - like from cellphone or just general MP4 ?

No problems with typical mp4 footage, whether it be from a drone, or another camera (or frankly, just transcoded to another codec mp4 of these R5 files). bit baffling.

I was reading about the latest TopazVEAI (upscaler) output files not being compatible with Vegas, I normally wait a couple of weeks before updating so don't have a sample file. That's not your problem though, the topaz file would not be able to loaded by anyone with Vegas, your problem is stranger, there seems nothing remarkable about your file.

Dear Magix staff...

"Warning: An error occurred while opening one or more files. The file could not be opened. Make sure the file exists and that you have access to the file/folder."

My guess... we all can open the file, so the issue isn't with VEGAS being generally incompatible with the file... so something with your system is preventing VEGAS from accessing the file properly... what, I couldn't even start to guess, but something is up there.

@HeavyMetal Just to put my oar in, this is what i get with that clip in VP19 & 20, I've tried different options in File I/O, maybe I'm missing something else.

OK, so the file imports, but playback is unstable with black frames... so we have confirmation of trouble with this file from one more user, this is a start. I see you have a 3090 GPU... I'm going to test this on my 3090 machine next. What driver version are you using?
