How Video Reframe Works

Upload your video

Drop in a clip at its current aspect ratio — for example a 16:9 YouTube cut or a 1:1 feed post.

Pick the target ratio

Choose 9:16 for TikTok and Reels, 16:9 for YouTube, 1:1 or 4:3 for feed placements. Each ratio sets the new canvas size.

Luma Ray 2 outpaints the edges

Instead of cropping, the model generates the added regions on the new sides so the original subject and action stay fully visible.

Download and publish

Export the reframed video and post it to TikTok, YouTube Shorts, or Reels. Reframe runs are priced per second of video.

Frequently Asked Questions

How do I change a video's aspect ratio without cropping it?

Use Video Reframe, which runs on Luma Ray 2. Instead of cropping the sides to fit a new ratio, the model outpaints the added regions — it generates new pixels on the edges so your subject stays fully in frame. You can convert between 9:16, 16:9, 1:1, and 4:3.

Can I turn a horizontal 16:9 video into a vertical 9:16 video for TikTok?

Yes. Upload your 16:9 clip and choose 9:16 as the target. Luma Ray 2 fills the new top and bottom areas by outpainting rather than zooming or cropping, so the original action is preserved in the taller vertical frame used by TikTok and Reels.

What aspect ratios does Viralance Video Reframe support?

Four ratios: 9:16 (vertical, for TikTok / Reels / Shorts), 16:9 (horizontal, for YouTube), 1:1 (square), and 4:3. You can reframe a single source video into any of these.

How is outpainting different from just cropping or adding black bars?

Cropping removes parts of your footage to fit the new shape, and black bars leave empty space. Outpainting with Luma Ray 2 instead generates new image content in the added regions, so the frame is filled and the original subject is never cut out.

How much does it cost to reframe a video?

Video Reframe is priced per second, so the cost scales with the length of the clip you process. Viralance uses one-time credit packages with no subscription, and credits are deducted based on the duration of the reframed video.

Can I repurpose one video for TikTok, YouTube, and feed at once?

Yes — that's the main use case. Reframe one source clip into 9:16 for TikTok and Reels, 16:9 for YouTube, and 1:1 or 4:3 for feed posts, instead of cutting separate versions for each platform by hand.
