@Nanozombi … the links you provided in your original post require a decryption code.

Perhaps you could copy/paste the MediaInfo data directly to a new comment on this forum post.

Your links cannot be opened while a key is needed, so we cannot look to them.
You have to use the latest build of Vpro 17 build 421, you now don't use.

Thanks for your answers,

here you have the details for the file that won't open (4K 60fps), I believe it is because it is using Motion JPEG codec which seems to be deprecated (I already enabled the QuickTime plugin in the deprecated features tab)

Links to the files have been fixed if you still need to see them 😊

This is the codec of your used problem file

that codec is not supported in Vegas Pro that you can cheque at the specs for this program, look

@Nanozombi

1. You are using the wrong build

2. You are using the wrong Nvidia driver, it is the latest Game driver and you need the latest Studio driver for your Nvidia GPU

3. Your first showed videofile has a codec that is not supported in Vegas, the other 2 showed files have supported codecs, look

Have you enabled QuickTime codec in Deprecated Features. It does support the older MOV/MJPEG format -- don't know about yours.

You may need to transcode everything in Handbrake -- these are not mainstream formats.

Dear j-v

Looks like my problem is only with the 3rd point, the codec used is not supported as far as I see, because the results are the same as it happens to you, the file with the MJPEG format does not open. The other 2 files open correctly.

Dear Musicvid,

Yes, QuickTime codec is enabled, but it does not work. Transcoding is an option, but very time-consuming. Usually I record children basketball games on Saturday morning, and in the afternoon all the other mf parents are already asking for the edited video 😂

If I have to wait until Handbrake transcodes them before starting editing, then I would not finish in time...

Thanks a lot for your help!
