Now using VIRB Edit v2.40 (Mac) and can no longer upload to YouTube (this used to work).
Uploading a 1080p 2min video (few hundred meg), takes a couple of hours normally because I have a slow upload on my broadband (500k).
Now after about an hour or so I get the error "YouTube Upload Failed, The operation couldn't be complete. (Invalid Credentials)".
I know the credentials are valid as i have tried many times and it accepts my email / password login to YouTube.
When I look at YouTube, I see the failures and YouTube reports them as "Failed (upload aborted)".
As a workaround ... Upload of the exported video works directly from YouTube website upload.
Has VIRB Edit 2.40 got a timeout and aborting slow uploads to YouTube (I saw from Change Control there were changes in this area)?
