Things to keep in mind when recording screens and PPT

When recording, you need to configure your screen and PPT considering the logos, subtitles, etc. that are automatically inserted on the actual lecture screen. Also, you must ensure visibility to deliver clear information.

Please follow the screen composition guidelines

Common screen composition rules to follow

Top-right margin

Since the CLASS101 standard logo is automatically displayed, the top-right background should be left empty and not black.

Bottom margin

Since subtitles (srt) are automatically displayed at the bottom of the screen, approximately 15% of the bottom should be left empty when composing the screen.

The lecture screen should be letterboxFill it completely without leaving any gaps.

PPT and PIP are displayed together

Considering fixed elements

You must compose the screen considering the logo position in the upper right and subtitle position in the lower center.

If there is no space for PIP, please remove it so that it doesn't obstruct the PPT content.
