What is the aspect ratio for my webinar video?

It depends on your original webinar video. If it was recorded as widescreen, then our system will automatically detect that and play the webinar video in widescreen 16:9

Otherwise, it will be adjusted automatically when encoding for an aspect ratio of 4:3

There's no video editing tools within Stealthseminar, if you want to adjust to our native widescreen format 16:9, that would need to be done with video editing tools at your computer, then uploaded again to your Library here.
