Hey guys,
Just purchased a licence 5.6.0.
Might be a rookie question...
I managed to render a first video and i'm now trying to render videos with different settings, but the render video button is grayed out.
I've checked all parameters. My temporary export JPGs haven't moved (still in the same subfolder)
See below
Any idea ?

From the screenshot you can see that you didn't choose a correct intermediary sequence for rendering. Most likely that folder is empty or has only subfolder. You need to "Choose" one of the exported intermediary sequences which begin with "LRT_" - then you'll see a preview in the render dialog and the render button will be active.

Thank you Gunther, it was a rookie question indeed
