I just found Youtube doesn't allow uploading thumbnail for shorts from desktop. So, I asked to ChatGPT and it said that you can do it using Opening Frame and it gave me an instruction. But it doesn't make sense to me.
The instruction sounds like just how to make thumbnail in Vegas Pro. So, I’m wondering if it’s possible to show my custom thumbnail for Youtube shorts with Vegas.
Is it possible? If yes, could you give me a guide, please? I'm using Vegas Pro 18.
