iMovie 11 won't allow me to export a movie in 1080p only 720p
I was uploading some footage that I took with my Panasonic SD5.
After finishing my 2nd and starting my 3th one, the 1080p option is greyed out and the only option available is 720p and below.
It's the same format as the first two, nothing changed, so Why now I'm unable to export to 1080p?
Is there a setting or a cache that I must empty from iMovie to allow me to use the maximum resolution to upload.
I tried to upload a 3.5Gb file via the youtube web interface and it was accepted by the server and once the file processed, it's available via 1080p.
So that's why I thing it's a problem with iMovie and not YouTube.
Anybody has any suggestion.
Thanks
