Reframe a Video and Review the Result
Choose the output shape, decide whether to crop or fit the source, and review the composition throughout the edit. The framing panel provides direct controls; chat can combine a framing request with other changes.
Documentation reviewed against the Studio controls and rendering implementation. The dimension examples below are calculations, not new production export measurements.
Use the Framing Panel
- Open the framing controls. Select the project and edit version you intend to change. Open the framing panel from the player and examine the source picture, including moments where the subject moves.
- Draft the composition. Choose source, 16:9, 9:16, 1:1 or 4:5. Fill crops the picture, Fit adds black bars and Blur adds a blurred backdrop. With Fill, drag the crop box to choose what remains visible. The panel selection is a draft until you apply it.
- Apply and review. Select Apply, then review the resulting edit and preview. Check all shot changes, faces, captions, titles and blur coverage. A panel thumbnail or immediately reshaped player is not proof that the new rendered preview is ready.
- Export the intended version. After any corrections, select the reviewed version and create its final MP4 in Studio. Wait for the original upload and final render to finish, download the file and inspect its actual dimensions and playback. Review and export each additional ratio separately.
For chat, state both the shape and what must stay visible: “Make this 9:16 with blurred bars; keep both speakers and the slide visible.” For a crop: “Make this 1:1 and frame the person on the left; check the shot change at 00:12.” These are example requests, not measured success claims.
What Fill, Fit and Blur Mean
| Panel control | Result and tradeoff |
|---|---|
| Fill | Crops to fill the output. Move the crop box to select the retained region; subjects or labels outside it are removed. |
| Fit | Scales the whole source composition to fit with black bars. Edge content stays present but can become small. |
| Blur | Fits the whole composition over a blurred version of the footage. The backdrop fills the gaps; it adds no new detail to the smaller foreground. |
In chat or tool documentation these modes are called crop, pad and pad_blur. Keeping the full composition means avoiding edge cropping, not preserving the upload's pixel values unchanged.
Framing Can Differ Across Shots
A manually chosen focus can move a crop away from the center. The editing system also supports source-time spans with different focus positions or fitting modes, so a wide two-person shot and a close-up can use different compositions within one output ratio.
Automatic reframing uses sampled visual evidence and can retain or create shot-specific framing when sufficient evidence is available. It can also fit uncertain material. Face position alone does not identify who is speaking, and samples can miss movement between frames. Check both the chosen person and the transition into the next shot.
This is not a guarantee of continuous motion tracking. For a person crossing the frame, inspect the whole movement and request fitting or a correction for the affected span. See automatic reframing for review prompts.
Understand the Dimensions Before Delivery
For a standard 1920×1080 main-video source, the framing logic calculates 1080×1920 for 9:16, 1080×1080 for 1:1 and 1080×1350 for 4:5. It derives the target shape from the source dimensions and rounds to even pixel sizes. Canvas projects and additional processing can have different composition rules; inspect the actual final.
A vertical crop of that landscape source retains a region about 608 pixels wide and enlarges it to the 1080-pixel output width. The output pixel count does not establish native detail. The blurred background may also be enlarged, and fitting can reduce the foreground size. Final encoding is not lossless.
The resize guide compares these dimensions and crop-versus-fit choices. The recorded square-crop example provides actual source and final files for one session, including its visible branding and ending.
Check the Reframed File
| Inspect | What to look for |
|---|---|
| Subjects and source detail | Faces, gestures, slides and screen controls remain visible at every relevant moment. |
| Captions and titles | Correct words, readable size, sensible line breaks and no collisions or clipped edges. |
| Blurs and zooms | Private details stay covered and zooms point at the intended region throughout the movement. |
| Final delivery | Correct version, actual dimensions, complete runtime, playable audio and acceptable branding; destination requirements checked separately. |
Account creation and uploads are free; indexing and agent editing require a subscription and available credits. New checkouts have no trial. Main-video uploads must meet both the 14 GB and three-hour limits.
The standard Valmera paid-plan policy omits overlay watermarks, but service settings can override it. Inspect the actual final file for branding and any end card. Use the export guide for the separate Studio final step and Plans for current terms.
Frequently Asked Questions
Which aspect ratios are available?
The main-video framing controls offer source, 16:9, 9:16, 1:1 and 4:5. These select a shape; they are not an arbitrary pixel-size field. Source restores the source aspect ratio and removes the explicit reframe, while other edits remain.
Do ratio buttons apply the change immediately?
The framing panel lets you draft the ratio, fill mode and crop position before selecting Apply. Review the new rendered preview after applying. The draft panel and the player's immediate visual feedback are not a completed final export.
Is cropping always centered?
A crop without a chosen focus defaults to the center. You can drag the crop position in the framing panel or ask the agent to frame a particular subject. Subject-aware framing can use sampled visual evidence and shot-specific positions, but the result still needs inspection.
Does the crop continuously follow a moving speaker?
Do not assume continuous subject tracking or correct active-speaker identification. The editing system supports framing that differs by source-time span, including different crop positions or fitting modes across shots. That does not guarantee a smooth crop path following every movement within a shot. Review the actual changes and use fitting when needed.
Will reframing preserve identical quality?
No. Final rendering uses source media rather than simply delivering the working preview, but scaling and encoding change the picture. In the standard main-video path, a 1920×1080 source can produce a 1080×1920 vertical output whose crop contains only about 608 pixels of source width. Enlarging that crop does not recover source detail.
Will captions stay readable?
Caption layout is rendered for the new output frame, but readability is not guaranteed. Check long lines, size, line breaks, title collisions and placement near the edges. Review captions in the downloaded final as well as the preview, then check the destination's interface and requirements.
Can I create several ratios from one upload?
Yes. Save a reviewed final for one ratio, change the framing, inspect the new version and create its final in Studio. You do not need to upload the previous export as the next source. Restoring the source ratio does not undo unrelated cuts, captions or effects.
