Reframe for Any Platform
One upload, four aspect ratios — 16:9, 9:16, 1:1, and 4:5 — filled with a crop, a pad, or a blurred-pad, chosen by pill or by plain English.
One Video, Every Platform
Valmera converts a video between 16:9, 9:16, 1:1, and 4:5 — the four frames that cover YouTube, TikTok, Reels, Shorts, and feed posts. You shoot once, edit once, and reframe the result for wherever it is going, instead of re-editing per platform.
Reframing is a core step in turning long videos into clips, and the reason social media managers can ship one piece of footage to every channel without a manual re-edit per format.
Three Ways to Fill the Frame
CROP
Cuts the new frame out of the original, centered. Best when your subject sits in the middle of the shot — a talking head, a screen recording, a product on a table. Note: the crop centers the frame; there is no automatic subject tracking.
PAD
Keeps the entire original frame and fills the leftover space with solid bars. Nothing is lost — the safe choice when every pixel matters, like slides or gameplay HUDs.
BLURRED-PAD
Keeps the whole frame and fills the space with a blurred, scaled copy of your own footage — the polished look you see on professional vertical reposts of widescreen video.
Ratio Pills or Plain English
The fastest route is the aspect-ratio pills in the player: one click on 16:9, 9:16, 1:1, or 4:5 switches the frame. When you also want to choose the fill style — or combine the reframe with other edits — type it in the chat instead: "make this 9:16 with blurred bars and bump the captions to XL."
Captions scale to the frame automatically, so a reframe never leaves you with tiny or clipped text. If a vertical version needs a different caption treatment, that is one follow-up message — see AI Captions & Subtitles for every style option.
Example Requests
"Make a 9:16 version with blurred bars"
Vertical for TikTok, Reels, and Shorts — the full frame stays visible over a blurred backdrop.
"Crop this to 1:1 for the feed"
A centered square crop — ideal when the subject sits mid-frame.
"Switch to 4:5 and keep the captions large"
Portrait feed format with the caption size carried over in the same request.
"Pad it back to 16:9 with black bars"
Return a vertical clip to widescreen without cropping anything away.
Honest Limits & Export Quality
No automatic subject tracking. A crop centers the frame — it does not follow a speaker who walks around the shot. If your subject is off-center or moving, use pad or blurred-pad so the whole frame stays visible. The agent will tell you this too: Valmera's honesty layer means it never claims a smart-tracking reframe it cannot do.
Exports keep source quality. Previews render from a fast proxy, but the final export renders from your original full-quality file — up to a 2GB upload — so a reframed export is cut from the real source pixels. Pair a reframe with a cleanup pass and captions and you have a per-platform version in a handful of requests — each charged in credits proportional to the work, on any plan from Free to Pro at $50/month.
Frequently Asked Questions
Which aspect ratios does Valmera support?
Four: 16:9 (YouTube, widescreen), 9:16 (TikTok, Reels, Shorts), 1:1 (square feed posts), and 4:5 (portrait feed posts). Each can be filled with a crop, a pad (solid bars), or a blurred-pad (a blurred copy of your footage behind the frame).
Does Valmera track the subject when cropping?
No. Cropping centers the frame — there is no automatic subject tracking. If your subject sits off-center or moves around, choose pad or blurred-pad instead, which keep the entire original frame visible.
Will reframing reduce my video quality?
No. Previews render from a fast proxy so iteration stays quick, but the final export always renders from your original full-quality file. A 9:16 crop of 4K footage is cut from the real 4K frame, not from the preview.
Do captions still work after reframing?
Yes. Captions scale to the frame, so a video reframed from 16:9 to 9:16 keeps readable captions in the position you chose — bottom, middle, or top. You can also ask for a different caption size per version.
How do I switch ratios — do I have to use the chat?
Either way works. The player has one-click aspect-ratio pills for 16:9, 9:16, 1:1, and 4:5, or you can type a request like “make this 9:16 with blurred bars” in the chat when you want to control the fill style at the same time.
Can I export the same edit in more than one aspect ratio?
Yes, iteratively: finish and export one version, then ask the agent to switch the ratio and export again. Each version renders from the original full-quality file, so nothing degrades between exports.
