When I want to share my vid on Youtube (File > Share > Youtube), and click on "settings" > click on the visible mailadress of my YT-account, then I get a white flickering block on the screen (see Share Youtube screenshot 1). When I cancel it, Share Youtube screenshot 2 appears.
It has always worked fine, and my YT-account works fine too. Who can tell me what causes this error?
While I dont have an answer for this exact question- I've found that sharing direct to a service (like YouTube in this case) is often prone to errors. I found when I was uploading straight from FCP to YouTube, sometimes it would error out, sometimes it would get all the way to the end and something else went wrong, and I'd have to wait all over again and try a new export.
The worst situation- it DID work and I would review it on YouTube and realize I made a mistake somewhere. Then fix the mistake and upload a whole new one again.
So instead I make it a point to always render out a local copy first.
I know its an extra step, but I've learned that by rendering a local copy first, I have a final to review before upload, and the YouTube interface for upload just works better all around.
It also has the added benefit of giving me a 'local master copy' just in case I ever decide to move my things off YouTube to another service, or in case YouTube changes its policy etc. I always have another copy of it.
Like I said, dont know if it helps,I believe having a local copy and uploading using the browser ends up working better.
And now I never have errors or have to wait for a new export to upload if/when it fails.
Great advice from AV-Ultra and I completely agree. To address the specific YouTube issue, I recall older versions of FCPX did have problems completing uploads. That may be a bug. Your version 10.2.2 is very old. Not sure if that's fixed in more recent versions and personally I have never used it.
