Video clips out of time sync with preview window?

[George Dean]

Jamie, use the free app Mediainfo in text mode and post the specs of your source media please.

Best Regards……George

[Jamie Watts]

Thank you kindly for responding.

I could/would do that if it was just this clip, but it appears to do this with all media sources. ☹ I recently experimented with a fresh picture from Google and it still did it.

Hi

So you got a Alienware Aurora R8 pc ! Your graphic card ? What kind of drives ?

Can you show us your timeline settings ? Your clip i 2h53m – what happens if you try with clips around 10min. ?

[Jamie Watts]

Hello.

Please note that I’m not too knowledgable with computers and mostly taught myself how to use Vegas.

Graphics Card:
NVIDIA GeForce GTX 1080.

Type of drive:
SSD.

Timeline Settings:
I’ve never deeply tinkered with the timeline settings; all settings are usually default. The only things that are ticked are Enable Snapping, Snap to Markers and Snap to All Events. I turn Quantize to Frames off when I want to be more precise with editing, but the problem still exists either way. As for the time, it’s set at “Times and Frame”.

I tried using a short video clip and picture. I also did a brand new install of Vegas. It’s still the same.

[Ole Kristiansen]

Hi !

It was easier to make a short video than to write a lot!
Do you create the Vegas Pro 16 timeline the same way I show in the video?

Hello. Thanks kindly for responding and I watched your video.

I don’t think I’ve ever done what you showed in the video, no, I’ve always just dragged the video clip into the program and started editing from there.

“Codec ID: isom (isom/iso2/avc1/mp41)”

Is your clip from screen recording using OBS, maybe it crashed while recording and made a corrupt file !

[Jamie Watts]

Hello.

I honestly don’t know. A friend converted the clip for me using their software months ago and gave it to me.

I did try your way of creating a timeline too. No luck; it still shows black in the preview window when I’m within the beginning of a clip. It’s the same with other clips and pictures I’ve tried too.
