Thats for a random video that I recorded with OBS. I'm unable to with every video/picture

@Will.l Hi thanks for that, I don't know much about MKV's, that is just the container but the contents say AVC & I thought they loaded into Vegas ok, I thought MKV HEVC were a problem but like I say I don't know much about them.

 I'm unable to with every video/picture

Is that everything, MP4's, png, jpg .... you can't insert anything into Vegas's timeline?

@Gid Yup nothing goes into the timeline although your post gave me an idea. I converted the video I had from MKV to MP4 and for some reason now I'm able to put the video and whatever photos on the timeline. The other videos still wont go so i guess I'll have to convert those to MP4 as well. Hopefully the problem eventually fixes itself but for now i guess that's an ok workaround

@Will.l 👍 Can you post MediaInfo of the other files that won't load, if the videos are all the same then fine you've posted that info but share the info of the photos. for curiousity & for the sake of sharing if nothing else 👍

@Gid Sure! Here's one that would not go into the timeline previously

@Will.l That's a normal jpeg 🤯 Why it wouldn't load I don't know🤷‍♂️😂

I wish i knew Vegas acts very strange sometimes but i appreciate the help a lot!

Vegas acts very strange sometimes

Strange behaviour is often fixed by a "Factory reset". Instructions here https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-reset-vegas-pro-to-default-settings--104646/

Make sure you tick the box to clear the cache which doesn't happen when you uninstall and reinstall.

Running anything as administrator prevents it from receiving drag-drop from anything non-administrator.

@EricLNZ Unfortunately that did not resolve this specific issue but thank you anyways, that's good information I didn't know you could do that

Don't run VEGAS as an administrator unless you want to import everything from within VEGAS.

@RogerS I am not running Vegas as administrator, i only tried the one time to see if that woule resolve the ussue but it unfiry did not

Hope you don't mind if I chip in, in the past i had this problem and it maybe worth trying to just drag the media by the outer frame and not the centre. It worked for me. (you must not be in Administrator mode).
