This is also called picture-in-picture when the overlay video appears as a smaller frame on top of the main video. ![How to Overlay Video on Video body visual](https://www.subclip.app/api/media/file/how-to-overlay-video-on-video-body-openai.png) Here is the practical workflow. ## Quick Steps 1. Open the main video in an editor. 2. Import the overlay video. 3. Put the overlay on a higher layer. 4. Resize and position it. 5. Sync the timing. 6. Adjust audio levels. 7. Add captions if needed. 8. Preview the final layout. 9. Export. ## Common Overlay Use Cases Use video overlays for: - reaction videos - screen recordings with a face camera - tutorials - podcast clips - gameplay - product demos - before-and-after comparisons - remote interviews The overlay should make the video easier to understand, not just busier. ## 1. Choose the Main Video The main video should carry the story. Examples: - screen recording for a tutorial - gameplay for a reaction - product demo for a walkthrough - interview footage for commentary The overlay adds context, emotion, or explanation. ## 2. Place the Overlay on a Higher Layer Most editors use tracks or layers. Put the main video on the bottom track. Put the overlay video above it. Resize the overlay so both videos are visible. Common placements: - bottom corner for face camera - side-by-side for comparison - top corner for reaction - full-screen cutaway for emphasis ## 3. Sync the Timing Bad timing makes overlays feel amateur. Check: - does the reaction match the moment? - does the face camera start at the right time? - does the screen recording match the explanation? - does the overlay disappear when it stops helping? Trim the overlay before styling it. ## 4. Adjust Audio If both videos have audio, choose which one matters. Usually: - keep the main narration loudest - lower background audio - mute the overlay if it is only visual - remove echo or duplicate audio - add captions if speech is important Poor audio ruins video overlays faster than imperfect layout. ## 5. Keep Captions Readable If the video has captions, make room for them. Do not place the overlay where captions need to go. For short-form video, check the platform safe area before exporting. Use [Add Subtitles](/tools/add-subtitles) or [Dynamic Viral Captions](/tools/dynamic-viral-captions) after the overlay layout is stable. ## 6. Export for the Platform Export settings depend on where the video will be posted. Use: - 16:9 for YouTube and landscape tutorials - 9:16 for Shorts, Reels, and TikTok - 1:1 only when the platform or layout needs it Preview the export before posting. Small overlay text can become unreadable after compression. If the final video is going to YouTube, use YouTube's [recommended upload encoding settings](https://support.google.com/youtube/answer/1722171) as a final export check. ## Common Mistakes ### Making the overlay too large The overlay should not cover the main action. ### Ignoring audio conflicts Two audio tracks at the same volume are hard to watch. ### Forgetting captions Captions need space, especially on vertical video. ### Keeping the overlay on screen the whole time Show it when it adds value. Remove it when it does not. ## FAQ ### What is picture-in-picture video? Picture-in-picture is a video overlay where one video appears in a smaller frame on top of another video. ### Can I overlay a reaction video on another video? Yes. Put the reaction video on a higher layer, sync it to the main video, and balance the audio. ### Can I add captions after overlaying video? Yes. It is usually better to finish the overlay layout first, then add captions where they will not be covered. ## Final Workflow Put the overlay video above the main video, resize it, sync the timing, fix the audio, keep captions readable, and export for the platform. That is the cleanest way to create picture-in-picture, reaction, tutorial, and screen-recording videos. ## Related Articles - [7 Best Free AI Dubbing Tools in 2026 (Tested + Compared)](https://www.subclip.app/blogs/dub-videos-free-ai-tools-compared) - Compare free AI dubbing tools for creators: Subclip, AI Dubbing, HeyGen, Veed, Synthesia, ElevenLabs, and Descript.
