I successfully uploaded a 6-minute video of a concert-band performance to YouTube. Watched it from YouTube. However, I then discovered that I had been logged in to the wrong YouTube account. I changed accounts and repeated the upload: "Error...Try again later." Several times.
A few years ago, I was given a solution to this identical problem which involved two steps: (1) create a You-Tube compatible disk file (2) upload disk file to YouTube. However, I didn't document this and when I came back six months later to upload another batch of performance videos, it wasn't necessary. Now, I cannot re-create this solution.
I found this response from March, 2012, to the first step of the desired procedure, which I duplicate below. However, I haven't tried it yet, so I'm hoping that PE10 hasn't changed in such a way that it no longer works. Also, though I must have figured it out a couple of years ago, it's not obvious to me to what folder the file created in this step should be uploaded.
From the Share tab, choose Computer and then QuickTime/MOV. Choose the DV preset and then click the Advanced button.
From the settings window, do the following:
*Video Codec: H.264
*Frame Wdith: 1280
*Frame Height: 720
*Frame Rate: 29.97
*Field Type: Progressive
*Pixel Aspect Ratio: square
*Set Bitrate: checked
*Bitrate: 8000 kbps
*Audio Code: AAC
*Output Channels: Stereo
Steve Grisetti's procedure worked fine within PE10 (with frame size 720 X 480) and the uploading is done from within YouTube, so one doesn't need to know the folder into which the Quicktime version of the video is to be moved.
