Work & mediaStep-by-step guide
Understand video thumbnails and playback
Know how saved posters help videos appear before they play.
The portfolio owner or a public visitor.
Here’s how to do it
Upload a supported gallery video and wait for the original transfer to finish.
Allow the uploader to finish its preview/poster step where shown.
Reload Work or the public page and check the video’s thumbnail.
Open the video and test actual playback separately from the poster.
If a preview warning appears, check the original before re-uploading; a poster failure does not necessarily mean the video upload failed.
What happens next
A successfully saved poster can display before the video starts.
Good to know
Older videos may have no saved poster, and browser codec support varies. There is no manual poster-replacement control introduced by this feature. Standalone Identity banner uploads are separate from gallery-video poster generation.
