I've used Camtasia for Mac quite successfully in the past for creating tutorial videos. I upgraded to Camtasia 2 yesterday, and since then have had all kinds of trouble with exporting to YouTube automatically and exporting to MP4 manually. TechSmith's support forums aren't that great for this particular product.
Here's my most recent upload, which shows about 1/4 of the video cropped out inexplicably: YouTube
This was exported automatically from Camtasia, not exported manually as an MP4 and then uploaded to YT.
My advanced export settings: Screenshot
My canvas settings: Screenshot
I filmed the video in 1280x720, which is the same size as my canvas.
The word "Codec" is tossed around in threads with different-but-maybe-related problems, but this is beyond my knowledge.
I have no idea what's going on. Help me, hive!
