I looked up on the forum but I didn't find anything like this, the button for upload is always grey and I tried on every single clip that I have it's always greyed... (on the top right of the screen
Thanks in advance !
You need to have a clip selected in order to upload it. You'll find the "Add Clip" button below the timeline on the right side. If you want to upload the entire thing, then just extend the clips range so it covers the entire thing.
Oh alright thank you, I'm such a noob !
