B-roll Remixes

Create a B-roll remix

Use No voiceover for footage and on-screen text. Switch to With voiceover when you need narration. See Voiceover Remixes.

Open a project. Select Remixes under Build ads in the sidebar, or select Create, then Remixes. Choose No voiceover at the top of the page. Remixes opens the mode you used last in this project, and each mode keeps its setup when you switch.
Choose a template. The selected template shows suggested shots and an example. Add your product and an optional supported benefit, or choose Custom brief to write your own instructions with at least 10 characters.
Check the ready-clip count and preview the thumbnail sample. Use all eligible footage or Selected footage to choose clips. Open Filters to exclude tags from every draft. In Selected footage, you can also filter and sort the clip list. Longer videos need analysis. Short clips from 1 second to under 4 seconds can also be used. Finished videos are excluded.
In Draft settings, set the opening text and music. The defaults are No text and Auto music. You can write opening text, choose saved hooks, set a music style, or choose No music.
In Draft settings, open Duration and choose 5, 10, 15, 20, 25, 30, 35, 40, 45, or 60 seconds. This sets the length of each draft. Choose 1, 3, or 5 drafts per hook. Add an optional Batch name so your team can find the batch later.
Check the summary bar at the bottom of the page and select Create drafts. The bar stays visible while you set up the batch. If the button is unavailable, the bar shows what is missing. Creating drafts uses no credits. Rendering finished videos does.

For saved hooks, use the Select button beside each hook in Messaging. You can choose up to three hooks. The buttons work with Enter or Space. Check the character count and use Show full text to read a long hook. Edit for this draft copies the full text into Write text. Shorten it to 200 characters before creating. The saved entry stays unchanged.

Each draft uses a 9:16 canvas. Source audio is muted. The selected hook guides footage selection and appears at the start. Its display time adjusts to its length. The saved hook text is copied when the batch starts. Later library changes do not change existing drafts.

Save and reuse ad briefs

Write an ad brief, then select Save as new brief. Enter a unique name and select Save brief. The copy is shared with members of this project.

Choose a brief from Saved briefs to load its exact text. You can edit it for the current batch. To keep those edits for later, save another copy with a new name. Existing saved briefs stay unchanged.

Only the ad brief text is saved. Hooks, footage, music, animated emphasis, duration, and draft count keep their current settings when you load a brief. Brief names can have up to 80 characters. Brief text must have 10 to 2,000 characters.

Filter footage

The footage controls use the same filters as Voiceover Remixes. In Selected footage, open Filters to choose campaigns, creators, locations, shoot dates, or Asset Bank tags. Search by file name. Sort by Newest, Longest, or Name.

Filters narrow the list. Select individual videos, or use Select all eligible to add matching videos up to the 200-video limit. This action keeps videos you already selected. Use Reset search and filters when no videos match.

Exclude tags is available in both footage modes. Footage with any excluded tag is not used, including replacement footage chosen during draft creation. Changing excluded tags clears the current clip selection. Choose your clips again after this change.

Animated emphasis

Choose Write text or Saved hooks, then turn on Animated emphasis below the hook. It starts off for each new batch. Select a starter style, a saved style, or Customize. The style controls and project defaults are shared with Voiceover Remixes and Auto-arrange.

The exact opening hook becomes one editable animated text graphic. It replaces the plain opening text. The full hook appears together. Its duration adjusts to its length and stays within the draft. Timing is not linked to speech. No new copy is generated. No text turns emphasis off.

The preview shows sample words and placement, not your finished draft. Save the style for this project to reuse its appearance. Existing drafts stay unchanged. If a hook cannot fit the animation format, the draft keeps its exact text as plain text and shows a review note.

Background music

Auto music chooses from up to 50 recent project music tracks that cover the full draft. Generated voiceovers are excluded. The choice uses track names and descriptions. If no track is long enough, it searches HeyGen once and imports the first full-length result. HeyGen imports use the existing active subscription requirement.

One saved track is reused across the batch. It is trimmed to the draft length, set to 50% volume, and given a 0.3-second fade-in and 0.8-second fade-out. You can change the track, volume, and fades in the editor. Fade limits use the trimmed clip length. The two fades cannot exceed that length together. Cuts are not synchronized to music beats.

If music cannot be added, the drafts still finish. Read Batch review notes and add a track in the editor. Existing drafts are not changed.

Review drafts

Open Recent batches. Batches are grouped as Running, Needs attention, and Finished. Use Search batches to find a batch by name or by its ID label, such as Batch AB12CD34. Open Filters to filter by status or creator, or select Created by me. Each batch shows who created it. Select a batch to open its drafts in a side panel. Select a draft poster to preview the saved video. Use Preview soundtrack to hear the full source track. Media loads only when you request a preview. Select Review draft to make changes in the editor. Screen readers announce changes to batch progress and completion. Load more batches keeps older results visible while active batches refresh. You can replace clips, change text, change music, and export in Video Editor.

Source clips shows the original clip names and source time ranges. Review clip plays that range. A Broader match note identifies a shot selected from analyzed footage as a fallback. Check that it supports your brief. These source details describe the original draft. The saved preview includes later editor changes.

Rename a batch or delete drafts

Open a batch, then open its actions menu and select Rename batch. Enter up to 120 characters. Leave the name empty to use the batch ID label.

Use Delete draft on a draft, or select drafts and use Delete selected. Use Delete batch in the batch actions menu to remove the whole batch. Check the draft and review counts before you confirm. Deletion is permanent. Source footage, music, and finished videos stay. Wait for draft creation or video rendering to finish before you delete.

Limits

The feature uses existing visual analysis and saved thumbnails. A batch can deliver fewer drafts when there is not enough suitable footage. Read Batch review notes for the cause. Incomplete visual timelines are not delivered.

If a batch stops, completed drafts remain available. Start a new batch to try again. There are no automatic retries. You can start up to 10 batches in 24 hours. A request that fails before the batch is saved does not count. Deleted batches still count.
