How does Instabatch extract Bluesky embed.video thumbnail URLs?
Bluesky post records include an embed object with thumbnail field pointing to a blob CDN URL (cdn.bsky.app). We parse the public page metadata and select the widest thumbnail candidate — never initiating a download of the video blob itself.
Will the Bluesky cover include player controls?
No. Play controls are rendered by the Bluesky client. We return the raw thumbnail blob asset.
Does this download the Bluesky video blob?
No. Only the static thumbnail image is fetched. Use our Video Downloader for full video files.
Do AT Protocol URI links work?
Paste the standard bsky.app/profile/.../post/... share URL for reliable metadata resolution.
What format are Bluesky video thumbnails?
Bluesky typically stores thumbnails as JPEG blobs on their CDN, sized to match the uploaded video aspect ratio.
Why download Bluesky covers for newsletters?
A clean blob thumbnail makes a professional email header or blog hero without screenshot artifacts.
