Looks like there is a dependency between the SX80 data sheet, admin guide, api reference guide, and the codec itself.
The SX80 itself only shows the following are supported:
- Auto
- 1280_720_50
- 1280_720_60
- 1920_1080_50
- 1920_1850_60
However, the data sheet show the noted resolutions above, as well as 1920_1200_50 and 1920_1200_60. Then you have the admin guide and api reference guide that show all the resolutions noted above, as well as many more that you list in your original post.
At this point, I'd open a TAC case and let them know about the difference in the documentation and what's available on the codec, and see what they say what if actually supported. That way, they can also update the documentation. You can create a TAC case from this discussion, so they can see what's already been said and saves you time from having to retype everything.
