Trade show and seminar videos 
Subtitles are added automatically to match the narration, so the content gets across even at venues with the sound turned down.
Use a video you've made as the reference to create videos with different content for each product.
From seminar video or audio recordings, you can create subtitled videos and highlight clips.
Choose horizontal 16:9 for booth monitors, or vertical 9:16 for social media announcements.
HOW IT WORKS
Use your product catalog and seminar slides as they are, in PDF or PowerPoint (PPTX). You can also paste invitation text into the input box.
STEP 01
Add your product materials or seminar slides, and write where the video will play.
STEP 02
Choose horizontal or vertical, then pick the narration voice and the presenter avatar.
STEP 03
Review the finished video, fix the script and subtitles, then export it as MP4 or publish it with a share link.
AT THE BOOTH
The large aisle-facing screen, the display stand screen, the meeting table. What you show depends on where it plays. Announcement videos before the show and thank-you videos after it can be made from the same product materials.

Make your first video from the catalog of your main product.
Choose the finished video as the reference and add the catalog for another product. The new video keeps the design and structure, with the content changed.

WHEN THE SHOW CHANGES
Show name, dates, booth number. For your next show, fix only what changes. Just fix the script and confirm, and the video becomes a new version.

Use "Regenerate audio" to regenerate the narration for that scene. Audio can be regenerated scene by scene.
Press "Confirm this content" and the video is regenerated as a new version.
Viewing, the share link, and downloads switch to the new version. The video URL stays the same.
The day your next show is confirmed, your announcement video can be updated too
Editing is done on a PC. Until you confirm, the published video stays on the previous version.

The narration and subtitles are in the language you choose. Images on your document pages and text inside slides are not translated.
