Give each scene enough time.

Inspect the whole video clock.

Open Video timeline below the studio preview. Scene, transition, primary audio, music and caption blocks share the finished video clock. Graphics and the footage inset appear for the selected scene. Select a block to pause at its start, then use the preview position control to inspect the rest. Choose Detailed to spread out short blocks and scroll the tracks sideways.

Overlapping scene blocks include their shared transition time. Removed passages collapse onto the finished clock. Audio duration comes from the loaded source; a dimmed block labelled “source length unknown” means its length is still unknown. The timeline shows placement, without measuring fades, ducking or loudness. Play the preview and review the exported file before approving it. Inspecting a block does not edit or save your video.

Review one timeline block.

Select a caption, primary-audio, music, graphic or footage-inset block. Drag the selected block itself to move its visible window while keeping its duration. Its window stays within the video, or within its own scene for graphics and insets. Audio and music move their entrance only. Drag Start or End directly below that block on the shared timeline to resize a window, then review the proposed times. The thin line marks the exact boundary; separate handle rows keep short blocks easy to select. Alternatively, choose Edit selected timing and use the form handles or enter exact seconds on the finished video clock. Arrow keys make smaller steps. The dashed range is the current block, and the filled range is the proposed window. Audio and music move their entrance only, shown by a line; source length still determines their end. Choose Review block timing to compare exact before/after times, then Apply block timing. Autosave is off, and one Undo restores the previous timing. Save video keeps a new version.

Graphics and insets must fit their own scene. Inset source start stays fixed, and its loaded footage must cover the new window. Caption wording and existing word times stay fixed; cue boundaries must contain those words and avoid neighboring cues. Source trim, audio speed, fades, music repeat and original files stay fixed. Restore removed video sections before editing blocks. If another part of the video changes during review, discard and reopen the current block. Every drag still needs explicit review and Apply. Moving a caption keeps its existing word times fixed; a window that passes those words is rejected. Multiple audio lanes and automatic speech alignment remain open.

Move a whole scene to another position.

In Video timeline, select a scene block, then drag it left or right toward another scene’s time. Release to propose its new position. For exact placement or keyboard use, choose Reorder selected scene and a New scene position. Choosing a position prepares a draft; your video keeps its current order.

Select Review scene order to see the entire proposed sequence, each scene’s length and the resulting video duration. Confirm your review, then choose Apply scene order. One Undo restores the earlier sequence. A click without movement creates no edit. Changing the position requires a fresh review, and another video edit disables the old proposal. Discard it and select the current scene again.

The scene’s words, length, graphics, inset, footage trim and incoming transition travel with it. Its original source files and saved storyboard remain intact. Global captions, recordings and music keep their existing video timestamps; they do not follow the moved scene. Play the full video and check their agreement. An incoming overlap may change the total length when it becomes active or inactive at the first position. Invalid transition windows, caption ends or audio entrances are rejected. Restore removed source sections before reordering.

Review pauses autosave and protects unsaved proposals when navigating or loading another version. After applying, save a new version, export it and watch the finished file. Moving a scene does not generate speech, approve a video or publish it.

Select the scenes, then choose their lengths.

1. Open Retime selected scenes in Video studio.
2. Select the scenes you want to change, or choose Select all scenes.
3. Choose Set one shared length and enter 1–30 seconds in tenths. For example, three six-second scenes become three two-second scenes: an 18-second video becomes six seconds when there are no overlapping transitions.
4. Alternatively, choose Scale current lengths. Half as long changes six seconds to three and four seconds to two, preserving their relative lengths. Choices are 0.5×, 0.75×, 1.25×, 1.5× or 2×; each result rounds to a tenth of a second.
5. Choose Review timing changes. Check every listed before/after duration and the resulting video length.

Review what moves and what stays fixed.

Changing a scene’s length moves later scene boundaries. Your words, original media, source trim, layout and colors remain. Existing recorded audio and timed captions keep their video timestamps; they do not stretch or follow moved scenes automatically. A voiceover that matched one scene may now reach into the next. Listen and inspect its caption alignment deliberately.

Scene graphics keep their local visibility and motion timing, so they must still fit the shorter scene. Overlapping transitions also keep their selected duration; their windows and total capacity must fit. The editor rejects an invalid whole-video proposal and leaves your draft intact. Choose a longer duration or adjust the relevant settings before reviewing again.

This control changes scene length, not a recording’s playback speed. Use audio and music pacing controls separately when you want to change the recording’s pace while preserving pitch. Review the combined result.

To keep total duration while moving nearby scene changes toward a known steady rhythm, use the supplied music-tempo review. It requires cut transitions and nonrepeating music; it does not detect beats.

Apply one edit you can undo.

Review pauses autosave. Choose Apply timing changes to update the draft; one Undo restores all affected lengths. Choose Discard timing review to leave them as they were. If you edit anything else during review, apply is disabled until you review the changed video again. A selection already at the requested lengths creates no edit.

Play across the new scene boundaries, then use Save video to keep a new version. Export that saved version and watch the finished file. Review does not save, export, regenerate speech or publish a video.

Keep source and export limits in view.

Each scene stays between one and 30 seconds; up to 30 scenes can be selected. The whole video must fit its current export profile: up to two minutes at a 720-pixel short edge, or one minute at 1080 when enabled, at 30 fps. Overlapping transitions have smaller explicit limits. Existing caption ends and audio entrances must stay inside the new video.

Batch edits can shorten footage scenes while retaining their original start and framing. To lengthen footage, edit that scene individually after checking the available source length. Restore removed video timing before retiming scenes whose original lengths are bound to word cuts. Original files remain unchanged.

For deliberate speech excerpts, use the caption passage and word-editing workflow instead. Retiming does not select spoken passages, generate extra footage or align a new recording automatically.
