Pick the source, choose where your facecam lives, record, then send the finished vertical MP4 to your camera roll or another app. **The recording idea:** The source and your facecam belong to one guided project. You can choose from six layouts, use small, medium, or large facecam sizing, and drag the facecam on the preview when you want a more personal placement. **When another editor fits better:** Use ClipDuet when the story is your live reaction to one source. A full timeline editor is the better choice when you need multi-clip storytelling, layered graphics, detailed color work, or frame-by-frame restructuring. **A repeatable take:** Choose the background first, then frame your facecam before pressing record. The workflow keeps the source and your camera in one project, so you are not manually aligning two recordings later. It is a good fit for a single clip and a live point of view; it is not a replacement for a timeline when you need several source clips or detailed keyframes. Tutorial video: A silent, music-backed walkthrough showing layout selection, reaction recording, trimming, export, and saving or sharing a finished ClipDuet. On-screen transcript: 0:00–0:04 Choose your layout and place your reaction where you want it. 0:04–0:12 Record your reaction with your face and background together. 0:12–0:16 Trim the clip to keep the part you want to share. 0:16–0:20 Export the video. The wait is shortened in this demonstration. 0:20–0:24 The finished ClipDuet is ready to save or share. Limitations: Yes. ClipDuet is built for iPhone and lets you pick a saved video, record facecam over it, and export a vertical MP4. Not for every job. It focuses on a single source plus a live facecam reaction; a timeline editor is better for complex multi-clip edits. Yes. Start a new ClipDuet and choose a video from the iPhone media picker, then continue to layout and recording. ClipDuet is designed around one source background per project. Use a full timeline editor when the story depends on assembling many unrelated clips. ### Pause a video while recording your reaction Freeze the source to finish a thought. Your facecam and microphone keep recording; resume the source where you left it. **The useful kind of pause:** During recording, Pause freezes the background video while your camera and microphone continue. It is useful when a clip moves on before you have said what you meant to say. **What the export does:** The freeze is preserved in the final reaction: the source holds while your reaction continues, so the exported clip can run longer than the original source. You can pause more than once. **A clean way to use it:** Pause at the moment you want viewers to inspect. Make the point, then resume instead of restarting your take. Check the pause marks in Quick Polish before export. **Why the final duration changes:** Every pause adds the time you keep talking to the exported timeline as a freeze. That means the output can be longer than the source, and a project near its plan duration cap can reach that cap sooner than the source length suggests. Check the estimated duration in Quick Polish before starting a server render. Limitations: No. The source freezes, while facecam and microphone recording continue. Yes. You can pause the source more than once during a recording. Yes. The held source frame and your continuing reaction are part of the exported duration. Pause time is stretched into the output. Several long pauses can push the final reaction over the applicable Free or Pro duration limit. You can review pause marks and trim the beginning or end, but detailed frame-by-frame editing belongs in a full timeline editor. ### Put facecam over a video on iPhone Set up a picture-in-picture reaction with a layout that gives the source room to breathe and your response a clear place to land. **Start with the source:** Choose a saved video as your background. Video backgrounds are available to all ClipDuet users. **Choose an intentional frame:** ClipDuet offers corner placements plus side-strip and bottom-band layouts. Small, medium, and large facecam sizes let you decide whether the reaction is a note or the main event. **Preview before the take:** Use the preview to see the vertical composition and drag your camera bubble into position. Fit, Fill, and Focus change how the background sits in the tall frame. **Match the layout to the conversation:** Corner presets keep the source dominant, while Side Strip and Bottom Band make the reaction more prominent. Small, Medium, and Large change the facecam footprint without changing the source. Fit shows the whole source with possible space around it; Fill uses more of the vertical frame; Focus favors the important center area. Preview these choices before recording because they change what viewers can read. Limitations: Yes. You can drag the facecam on the preview to fine-tune placement. ClipDuet includes six facecam layout presets, with three size options. ClipDuet provides Top Left, Top Right, Bottom Left, Bottom Right, Side Strip, and Bottom Band presets. Fit preserves the whole source, Fill fills more of the vertical canvas, and Focus prioritizes the source area you want viewers to notice. You can adjust facecam placement and crop choices during Quick Polish; set the size intentionally in layout before recording for the cleanest composition. ### Build reaction highlights with emoji markers Mark the moments you want to find again while recording, then use those marks to build a shorter highlights reel. **Three signals, one purpose:** While recording, ClipDuet offers fire, laugh, and mind-blown marker types. Markers appear in the export and give the highlights tool moments to work from. **Highlights are selected, not magical:** In Quick Polish, choose Highlights instead of Full Video. The app builds short segments around marked moments; you can focus the selection on fire markers when that matches your cut. **A practical ceiling:** Highlights support up to 25 segments. Nearby marked moments can merge into a single segment, so marking deliberately gives you a clearer shortlist. Markers retain their timing even when you pause the source. **Mark on the recording timeline:** Markers follow your reaction timing, including time spent talking while the source is paused. Nearby marked moments may merge into one segment, which keeps a burst of reactions from producing repetitive cuts. The 25-segment ceiling is a practical reason to mark the moments that carry the story rather than tapping every beat. Limitations: The three marker types are fire, laugh, and mind-blown. A highlights export has a ceiling of 25 segments. Yes. Marker timing includes the recording time spent during a source pause, so the marker remains attached to the moment you reacted. Nearby highlight windows can merge. This avoids tiny back-to-back segments and produces a more watchable cut. Highlights have a 25-segment ceiling. Narrow your markers or use fire-only selection when you need a shorter shortlist. ### Use Auto-duck for clearer reaction audio Let the source stay present while your own voice takes the lead—then choose the recording setup that makes that behavior easier to hear. **Four practical choices:** Source audio can be On, Low, or Mute. With Duck enabled, ClipDuet lowers source audio based on facecam audio so your reaction has more room. **The microphone caveat:** Duck is most reliable with a headset microphone. If the iPhone speaker is bleeding into the native microphone, that speaker audio can mask your voice and make ducking less dependable. **Pick for the clip:** Mute suits commentary that needs no original sound. Low is a restrained middle ground. On with Duck works when the source context matters and you want your voice to come forward while speaking. **A setup that avoids false confidence:** Headphones or a headset mic make the source and facecam voices easier to separate acoustically. With the native mic, iPhone speaker bleed can resemble your reaction audio and mask the signal Duck uses. Auto-duck is an audio aid, not studio isolation: listen back, and choose Low or Mute when the source is more distracting than helpful. Limitations: It lowers source audio based on facecam audio to help your reaction voice lead. It reduces iPhone speaker bleed into the native microphone, which can otherwise mask your voice. No. Duck lowers source audio while you speak; Mute removes the source audio. On and Low keep different amounts of source context. No. It cannot guarantee isolation. Speaker bleed into the native microphone can make automatic ducking less dependable; a headset is the safer setup. Choose the source mode and Duck setting in the recording workflow. Review the result before exporting rather than assuming the mix will fit every clip. ### Video or photo background for a reaction? Choose movement when the thing you are reacting to unfolds in time. Choose a still when your explanation needs the frame to hold. **Video: the live context:** A video background plays while you react, and you can pause it to keep talking. Video backgrounds are available to every ClipDuet user. **Photo: a fixed reference:** A photo is useful for reacting to a post, a frame, or an image where you want the background to stay still. Photo backgrounds are a ClipDuet Pro feature. **Choose from the story:** Use video for a sequence, timing, or reveal. Use a photo when the spoken reaction is the motion. Both formats use the same vertical facecam workflow. **A plan decision, not just a media decision:** Video is the right choice when timing, motion, or a reveal is part of what you are discussing; it also enables Pause while you keep talking. Photo is the right choice for a still post, screenshot, or visual reference. Photo backgrounds require Pro, while video backgrounds are available on Free and Pro. Neither choice promises support for every source file or a substitute for a multi-source edit. Tutorial video: A silent, music-backed example showing a screenshot held as the background while the creator explains it on camera. On-screen transcript: 0:00–0:02 Turn a screenshot into a video. 0:02–0:10 Use a screenshot as a fixed background while giving an on-camera explanation. 0:10–0:12 ClipDuet for iPhone at clipduet.com. Limitations: Yes. Video backgrounds are available to all users. Yes. Photo backgrounds require ClipDuet Pro. No. Photo backgrounds require Pro. Free users can still use video backgrounds. A photo is already still, so the source-pause control is relevant to video backgrounds. Your facecam recording continues normally over a photo. Choose a photo when the visual reference should stay fixed; choose video when the timing of the original clip is part of your commentary. ### ClipDuet Free vs Pro: what changes? A straightforward feature comparison, without hard-coded prices: Apple presents localized live pricing and any eligible trial details. **Free:** Free includes video backgrounds, three starter exports, then one export per rolling seven days. Free exports support up to five minutes at 30fps and include a ClipDuet watermark. **Pro:** Pro includes unlimited exports, photo backgrounds, videos up to 30 minutes, optional 60fps export, and no watermark. **How pricing works:** Monthly and yearly prices are supplied by Apple in local currency. Trial eligibility and its terms, if offered, are also shown by Apple before purchase—not promised on this page. **Compare the workflow, not a headline price:** Free is enough to test a video-background reaction within its allowance and output limits. Pro is the relevant choice for recurring exports, photo reactions, longer projects, optional 60fps, and a clean export without the watermark. Apple supplies localized monthly or yearly pricing and determines whether an introductory trial is available, so ClipDuet does not publish a universal price or promise eligibility. Limitations: Free users get three starter exports, then one export per rolling seven days. Yes. Pro exports have no ClipDuet watermark. After the three starter exports, Free provides one export per rolling seven days. Free supports videos up to five minutes, exports at 30fps, and includes a ClipDuet watermark. Pro adds photo backgrounds, up to 30-minute videos, optional 60fps, and no watermark. Apple shows the live local price. ### Export a vertical reaction video from ClipDuet Take a live reaction from Quick Polish to a shareable 9:16 MP4, with clear expectations about server rendering. **Choose the cut:** Quick Polish lets you select Full Video or Highlights. You can trim the start and end, review pause marks, reposition facecam, and choose Fit, Fill, or Focus before exporting. **The file you receive:** ClipDuet exports a vertical 9:16 MP4. When rendering completes, save it to your camera roll or share it to another app. **You can step away:** Exports are rendered on ClipDuet servers. You can leave the export screen and check the project later; ClipDuet does not send a completion notification, so return to the project to see its status. **What happens after you tap export:** The source and facecam media are uploaded for server rendering rather than finished entirely on the phone. Longer output—including pause-stretched output—can take more processing time. You can leave the screen and later reopen the project, but there is no completion notification. When it is done, save the MP4 to your camera roll or use the share action. Limitations: ClipDuet exports a polished vertical 9:16 MP4. No. You can leave and check the project later, but there is no completion notification. No. You can leave and check the project later. Reopen the project to inspect progress because ClipDuet does not send a completion notification. When the export is ready, ClipDuet offers save and share actions for the finished vertical MP4. ClipDuet's guided export is a vertical 9:16 MP4. A different delivery canvas is a reason to use a full editor. ### How ClipDuet handles your media A plain-language look at why media is processed, how long it stays available, and what ClipDuet does not do with your data. **Why media is uploaded:** Source media and facecam recordings are uploaded solely to render the final export. This processing enables the merged reaction video. **Temporary by design:** Temporary media is deleted after export or within 24 hours. ClipDuet does not keep uploaded media as a long-term library. **Tracking and account context:** ClipDuet does not track you across other apps or websites and does not sell your data. If you create an account, email and username help provide the service; basic device and usage information supports export tracking and analytics. **What account deletion does and does not mean:** Deleting an account removes account-linked service records from the app flow, but it does not cancel an Apple subscription; subscriptions remain managed in Apple ID settings. Temporary uploaded media follows the export/24-hour deletion policy. Basic device and usage analytics can support export tracking and service improvement, and historical analytics may require a support request for deletion. Limitations: Temporary media is deleted after export or within 24 hours. No. ClipDuet does not sell data or track users across other apps or websites. No. Source and facecam uploads are used solely to render the requested export and are deleted after export or within 24 hours. No. Account deletion and App Store subscription cancellation are separate; manage the subscription through Apple ID settings. ClipDuet uses basic device and product-usage information, such as screens, taps, and subscription status, to operate and improve the service. It does not track across other apps or sell data. ### ClipDuet export troubleshooting A focused checklist for exports that are still processing or do not look ready to share. **First, check the project:** Rendering happens on ClipDuet servers. If you leave the export screen, open the project again to check progress; completion is not delivered as a notification. **Check the project limits:** Free exports allow video projects up to five minutes at 30fps with a watermark. Pro supports projects up to 30 minutes, optional 60fps, and no watermark. **If audio is not behaving as expected:** For Duck, try a headset microphone. Speaker bleed into the native iPhone mic can mask facecam audio and make the automatic source-audio reduction less reliable. **Still stuck?:** Use the support page to email ClipDuet with what happened and the project state you see. Avoid deleting a project you still want to inspect. **A careful troubleshooting order:** Confirm camera and microphone permissions, enough device storage for the temporary recording, and a stable network for upload. Then check the source duration plus any pause-stretched time against your plan limit. If rendering is already active, preserve the project and reopen it later rather than repeatedly starting new exports. Limitations: Yes. Leave the export screen and check the project later. Try a headset microphone, since iPhone speaker bleed into the native mic can mask your voice. Check iPhone camera and microphone permissions for ClipDuet, then verify the selected media is accessible in Photos. Yes. Source and facecam media upload for server rendering, so an unstable connection can interrupt or delay the export. No. Preserve the project while checking its status and contact Support with the project state if it remains unresolved. Yes. Pause time is included in output duration, so trim or reduce pauses when the final estimate reaches the Free or Pro limit. ## Public pages - https://clipduet.com/ - https://clipduet.com/guides - https://clipduet.com/updates - https://clipduet.com/updates/clipduet-1-0-25 - https://clipduet.com/updates/clipduet-1-0-24 - https://clipduet.com/updates/tutorial-videos - https://clipduet.com/updates/search-discovery - https://clipduet.com/updates/export-reliability - https://clipduet.com/reaction-video-maker-iphone - https://clipduet.com/pause-video-while-recording-reaction - https://clipduet.com/facecam-over-video-iphone - https://clipduet.com/reaction-highlights-with-emoji-markers - https://clipduet.com/auto-duck-reaction-audio - https://clipduet.com/video-vs-photo-reaction-background - https://clipduet.com/clipduet-free-vs-pro - https://clipduet.com/export-vertical-reaction-video - https://clipduet.com/clipduet-media-privacy - https://clipduet.com/clipduet-export-troubleshooting - https://clipduet.com/support - https://clipduet.com/privacy - https://clipduet.com/terms - https://clipduet.com/challenge ## Product facts - Video backgrounds: all users.
