What does Sizzledraft capture from a YouTube channel?

It captures the channel banner, visible video thumbnails and subscriber count from the page opened by its browser. Those assets provide the visual source for the scenes. It does not need invented channel artwork, although the result depends on what the page displays when it is captured.

Will thumbnail text stay readable in a vertical ad?

The edit reframes 16:9 thumbnails for a 1080x1920 canvas and avoids relying on a blind centre crop. Readability still depends on the original thumbnail. Small episode text, edge-aligned faces and crowded layouts may need a wider presentation within the scene rather than a close crop.

Can I tell the ad which uploads to feature?

The first video is cut from the channel page alone, using the information visible there. For later versions, you can provide a prompt that asks for a particular series, topic or audience angle. The requested focus still needs to match thumbnails and channel details available from the source page.

What video formats can I export for my channel campaign?

Vertical videos render at 1080x1920, while horizontal videos render at 1920x1080. Both use 30fps and H.264, with audio normalised to -14 LUFS. The vertical format suits feeds where a YouTube thumbnail needs reframing; horizontal preserves more of the thumbnail's original 16:9 composition.

Make an ad from your YouTube channel page

Sizzledraft turns a YouTube channel URL into a short video ad using the channel banner, video thumbnails and visible subscriber count. It reframes 16:9 thumbnail artwork for vertical scenes, renders at 30fps and exports an H.264 video ready for publishing.

How do I turn my YouTube channel into a video ad?

Paste the URL of the YouTube channel you want to promote. Sizzledraft drives a browser at the channel page, captures the banner, visible thumbnails and subscriber count, then builds scenes using those real channel assets and their colours. The first video is cut from the site alone, so the result reflects what a visitor can actually see on the channel. Later videos can take a prompt, such as focusing on a particular series, upload theme or audience. The finished ad is rendered frame by frame at 30fps and exported as H.264. Choose 1080x1920 for vertical placements or 1920x1080 for horizontal placements. Audio is normalised to -14 LUFS for consistent playback.

How are YouTube thumbnails adapted for a vertical ad?

YouTube thumbnails start in a 16:9 frame, while a vertical ad uses a much narrower 1080x1920 canvas. A direct centre crop can remove a host's face, cut episode text in half or hide the object that explains the video. Sizzledraft reframes the captured thumbnail within a scene rather than treating every image as a full-screen crop. The scene can preserve the complete thumbnail, enlarge a useful region or place it alongside channel branding and copy. This keeps the upload recognisable while using the vertical space deliberately. Channels should still review thumbnails with important text or faces near the outer edges, because those compositions leave less room for close reframing.

Can a channel ad use a trending sound?

Yes, but the trending sound is handed over as a link so you can attach it inside the publishing platform. It is not baked into the exported channel ad. Native attachment matters because uploading a file that merely contains the same audio does not count as using that platform sound. The rendered video can still include its scored audio, normalised to -14 LUFS, for versions that do not need a trend. When publishing a trend-led version, use the supplied link, add the sound natively and set the mix for the final placement. This workflow keeps the visual edit built around your banner and thumbnails while leaving the platform-specific sound step in the correct place.

What the browser actually gets

The browser opens the YouTube channel page and captures the visible banner, video thumbnails and subscriber count. The main difficulty is adapting 16:9 thumbnails to vertical video without cutting off faces, titles or the subject that makes each upload recognisable.

The common mistake

A common mistake is shrinking several YouTube thumbnails into one vertical frame until none of their titles or subjects are readable. Feature fewer uploads, give each thumbnail its own scene and reframe around the face, object or episode title that identifies the video.

YouTube thumbnails are designed at 16:9, so faces, episode titles and key objects can disappear when cropped into a 1080x1920 ad.
A channel page contains many thumbnails competing for attention, making it hard to choose which videos should carry the ad's message.
Subscriber count, banner branding and thumbnail styles often use different visual scales, so combining them into one short ad can look disjointed.
