Can you also share MediaInfo for the c001?

What camera or cameras are these files from?

@Rui-Nunes

There is nothing about your file that should prevent opening in any version of Vegas.

To get prompt action on your discovery, please include the words [Bug Report] in the title of your topic. Thanks for your report.

FYI- it's not possible to edit posts beyond a short time after posting any longer.

@Rui-Nunes Would you also be able to provide a short sample file from this camera via Google Drive or another service? AVC really should open in VEGAS. It would be good to confirm if this is only an issue on your system or an issue with VEGAS in general.

here are Sample Video MP4 in Link of Fujifilm X-S10 Review.

after downloading upper link's mp4, i had imported it in Vegas Pro 21 build 300 and it's Working!!

it read Magix AVC with mxcompoundplug.dll in Vegas Pro as like screenshot.

Thanks everyone. I also have a number of Fuji files here and they all work, so I'm curious what the issue with the OP is.

@Rui-Nunes Maybe try resetting VEGAS? Here are instructions.

Also the files that work are labeled c001 which indicates Sony. All my cameras are Sony and all formats they shoot work in VEGAS, so that's expected.

Ive set to default settinggs and still doesnt read the file.

Ive got another fuji that all videos appear i dont know if they are recorded in diferent formats.

But this way its impossible to use vegas to edit.

You can take screenshots with windows + shift + s or the prtscn key.

VEGAS doesn't normally have any issues with AVC in MP4 containers.

If you go to preferences/ file io and check "enable legacy AVC decoding" does that help?

Could you upload the file that doesn't work somewhere (Google Drive?)

And here is google link with video :

The video is fine here as well.

Are your GPU drivers up to date? Help/ driver update in VEGAS can help find the latest.

That picture is from VP18 but it loads ok on there & VP21 without a problem.

That file has Quicktime mentioned at the bottom of MediaInfo, does that mean Quicktime is needed or doesn't it matter ? 🤷‍♂️ (I have Quicktime installed)

QuickTime isn't needed for AVC (or HEVC or ProRes, etc.)

@RogerS Thanks I thought so but what's the bit at the bottom about Timecode.. Quicktime ?

I suppose it uses a Quicktime format for timecode? All MOV files also say Quicktime. That doesn't have any bearing on how VEGAS decodes it though.

@RogerS Thanks.

Yes i have the latest adrenalin software up to date i even changed to software edition from Amd , they say its better for video editing but still dont show video. And when i close vegas it says error occurred. I also reinstalled vegas and still the same :(

I formated the computer a few weeks back but i also have k-lite codeks and also quicktime instaled.

I really cant fiigure it out

 

...  i also have k-lite codeks and also quicktime instaled.

Over the years, some regular forum members have shuddered on learning that a 3rd party codec pack is installed on the computer - particularly K-Lite.

Try uninstalling K-Lite, run a registry cleaner such as the free CCleaner, and see if K-Lite is the cause of the problem.

When you get an error message, can you click show problem details and see the error message and copy and paste it in here? Sometimes it offers a clue.
