The embed iframe is the right size, but the video sits in a smaller area with empty black space around it. This usually happens with a video-only embed. Video + article often looks fine because that iframe is taller.
Clevera does not crop or stretch the recording. The player keeps the video’s real shape so UI, captions, and title cards stay intact.

​
Why it happens

The Share embed wrapper is 16:9 (padding-top: 56.25%). Many recordings are not — window captures are often 3:2 or 4:3. A 3:2 video inside a 16:9 box cannot fill both width and height. The player fits the video without cutting it, so you get black bars on the sides (or top and bottom for a taller video).

​
Remove the leftover bars

Change the iframe box to match the video. Do not crop or stretch.
  1. In Clevera, open the screencast and note the recording size (for example 1380×960 or 1440×960).
  2. Copy Share → Embed → Video only.
  3. In the wrapper div, replace padding-top: 56.25% with the value for your ratio, or use aspect-ratio instead.
3:2 example (1440×960, 1380×960):
Same result with the older padding trick: padding-top: 66.67%.

​
Common wrapper values

Formula if your size is not in the table: (height ÷ width) × 100 = padding-top.
WordPress, Help Scout, and similar hosts style the outer iframe only. They cannot restyle the player inside share.clevera.ai. Matching the wrapper to the video is the change that removes the bars.

​
What not to do

  • Do not switch to a static MP4 just to control size. You lose LiveSync: the iframe updates when the Clevera video changes; an exported file does not.
  • Do not scale the video to “cover” the 16:9 box. That crops the top and bottom.
  • Do not stretch the video to 16:9. That distorts the picture.

​
Still seeing a large empty frame?

If the video is small on all four sides (especially extra space below), that is not an aspect-ratio leftover. Confirm you are using a video-only embed (type=video or mode=video-only), then contact support — the player should fill the iframe, with bars only where the shapes still differ.
