An interesting question came up that others may have: What are the supported video input resolutions for Connect? I am testing a Matrox MXO2 Mini that allows me to send a variety of different resolutions through a USB shim that can be used in Connect. I have tried a number of resolutions that will either not show a full frame of video or no video at all. Can I get a list of the supported video input resolutions?
Another question came up on the same topic that will be of interest. Similar to something Hippasus might ask Pythagoras: If there are three supported resolutions per aspect ratio why are there four settings for video quality under video preferences?
Answer: Apart from Video Resolution, there are other parameters as well which define the video quality such as Frames/sec and Video Compression Quality. These four settings have different combinations of these variables:
Resolution Frames/sec Video Compression %
High 640×480 20 90
Standard 320×240 10 80
Medium 320×240 8 75
Low 160×120 4 70
For the 16:9 aspect ratio, the settings are the same as their 4:3 counterparts. For example, if 4:3 resolution for any quality setting is 320×240, then its 16:9 counterpart will always be 427×240.
