Use it when a shot is close, but one moment needs a new action, a different object, cleaner timing, replacement audio, or a more specific beat. Chat Video Pro uses **LTX Retake** to regenerate the selected segment while using the surrounding clip as context. Think of it like asking for a new take inside an existing shot. ### What This Tool Is For Reshoot is for **targeted retakes**. It is not a general style filter, rotoscope tool, or long-form editor. Use it to: * Regenerate one short moment in a clip. * Change what a person or object does. * Add, remove, or alter a scene element. * Replace a short section of audio. * Fix a small scene issue without reworking the full video. * Try a different action while preserving the surrounding shot context. {% hint style="info" %} **Reshoot answers: "What should happen differently in this selected segment?"** The clearer that answer is, the better the result. {% endhint %} ### When To Use It Use Reshoot when the main problem is a specific moment, action, or element:
GoalWhy Reshoot helps
Change a short actionRegenerates the selected moment with a new prompt.
Replace a scene detailLets you modify an object or part of the shot.
Fix a bad beatGives you a new version of a specific time range.
Regenerate audio and video togetherAV Sync mode creates a synced replacement take.
Regenerate only audioAudio Only mode can change sound while keeping the picture.

Reshoot is strongest when the request is local and concrete. If you want the entire clip to become cyberpunk, snowy, noir, or golden hour, use Add Effects or Relight Scene. *** ### Studio Path The fastest route is through Studio. 1. Open **Studio**. 2. Choose **Reshoot** from the Post-Production department. 3. Load a video from upload, Recents, or your Premiere timeline. 4. Drag the timeline handles to select the segment you want to regenerate. 5. Describe the new content or change. 6. Choose the retake mode: **AV Sync**, **Video Only**, or **Audio Only**. 7. Click **Reshoot Segment**. 8. Compare the result and click **Done** when you want to send it back to your chat/library. Studio opens the video editor directly in LTX Reshoot mode. You do not need to manually choose the model. ***
### Classic/Editor Path You can also use Reshoot from the classic video editor path: 1. Import or generate a video. 2. Click **Edit** on the video thumbnail. 3. Choose **LTX Reshoot** from the model selector. 4. Select the segment. 5. Write the reshoot prompt. 6. Choose retake mode. 7. Generate and review. This path is useful when you are already working from a chat result. For new targeted fixes, Studio is cleaner because it opens the correct tool immediately. *** ### Controls And Constraints

*** ### Retake Modes #### AV Sync Use **AV Sync** when the new moment needs picture and sound to work together. Best for: * A person saying or reacting differently. * A new action that should have matching audio. * A scene beat where motion and sound both matter. * Generating a fresh take of the selected moment. #### Video Only Use **Video Only** when the picture should change but the original audio should stay. Best for: * Removing or modifying a visual detail while preserving dialogue or music. * Changing a movement while keeping production sound. * Fixing the look of a segment without touching audio timing. #### Audio Only Use **Audio Only** when the visual is fine but the sound needs a different take. Best for: * Replacing a sound moment. * Trying a cleaner audio beat. * Keeping the original video while exploring generated audio changes. *** ### Writing Reshoot Prompts Reshoot prompts should describe the replacement moment as directly as possible. Good prompts: ``` The person waves goodbye at the camera. ``` ``` Remove the small sign on the wall and keep the background natural. ``` ``` The car changes from blue to red while keeping the same movement. ``` ``` Replace the old poster with a clean blank wall. ``` ``` The person looks down at the product and smiles. ``` Less effective prompts: ``` Make it better. ``` ``` Make it cinematic. ``` ``` A person walking through a city. ``` The weak prompts either do not say what should change or sound like a request for a brand-new clip instead of a targeted retake. #### AI Optimize ✨ Tap the sparkle (✨) button next to the reshoot prompt to get an AI-improved version of your retake description. The optimizer understands the retake description and the source clip — so the result is a concrete, targeted replacement rather than a vague rewrite. Choose **Replace** to apply it, **Regenerate** to try again, or **Close** to keep your original. *** ### Best Practices #### Select The Smallest Useful Segment Do not reshoot the whole clip unless the whole clip needs a new take. Shorter segments are easier to control and easier to judge. Good segment choices: * The 3 seconds where the person reacts. * The 5 seconds where an object should change. * The one beat where the audio should be replaced. Riskier segment choices: * A full 20-second section with several unrelated actions. * A segment where the subject enters and exits frame multiple times. * A broad scene change that should really be a new generation or VFX pass. #### Say What Changes And What Stays If parts of the shot should remain stable, include that in the prompt. {% code overflow="wrap" %} ``` Change the blue car to red while keeping the same street, camera movement, and traffic timing. ``` {% endcode %} ``` Remove the cup from the desk. Keep the person, laptop, and background unchanged. ``` This helps LTX focus the retake instead of reimagining the entire selected moment. #### Use Reshoot For Scene Logic, Not Broad Style Reshoot can add or change scene elements, but it is not the best tool for broad atmospheric transformations. If the note is "make this night with rain and neon," use Add Effects. If the note is "change this cup into a phone for the next 4 seconds," use Reshoot. #### Start With Video Only When Audio Matters If you are editing footage with dialogue, music, or production sound you already like, try **Video Only** first. It keeps the audio stable while changing the picture. Use **AV Sync** when the new video action needs new sound to make sense. #### Compare Before Committing Watch the transition into and out of the selected segment. A good reshoot is not just a good generated middle; it should also cut back into the original clip cleanly. *** ### Examples #### Change A Product Moment * Segment: 4 seconds where a product is held up. * Mode: Video Only. * Prompt: `The person holds the product closer to camera and turns it slightly toward the light.` * Result: A more useful product beat while preserving the original audio. #### Remove A Small Scene Element * Segment: 3 seconds where an unwanted poster is visible. * Mode: Video Only. * Prompt: `Remove the poster on the back wall and replace it with a plain wall. Keep the person and camera movement unchanged.` * Result: Cleaner background without running a full object-erasing workflow. #### New Reaction Take * Segment: 5 seconds on a character reaction. * Mode: AV Sync. * Prompt: `The person notices something off camera, smiles, and says a short surprised reaction.` * Result: A new action/audio beat for the same moment. #### Audio Retake * Segment: 4 seconds with distracting sound. * Mode: Audio Only. * Prompt: `Replace the noisy audio with clean room tone and subtle footsteps.` * Result: Same video with a cleaner generated audio moment. *** ### Troubleshooting #### The result changed too much Shorten the segment and add preservation language: {% code overflow="wrap" %} ``` Keep the person, camera movement, background, and timing unchanged. Only remove the cup from the desk. ``` {% endcode %} #### The requested change did not happen Make the prompt more concrete. Name the object, action, location, and what should replace it. ``` Replace the blue sign on the left wall with a blank white wall. ``` #### The wrong part of the clip changed Adjust the timeline handles. Reshoot only knows the selected segment, so make sure the selection starts before the change and ends after it has enough time to complete. #### The selected segment is too short LTX Retake requires at least 2 seconds. Expand the handles so the segment is 2 seconds or longer. #### The selected segment is too long Keep the selection under 20 seconds. For more control, split a long change into shorter beats and process them separately. #### Processing fails on the source clip Try exporting the segment from Premiere as a short H.264 MP4, then use that as the Reshoot source. Chat Video Pro prepares incompatible formats when possible, but clean H.264 sources are the safest input. *** ### Links To Related Studio Pages * [Studio](/features/studio.md) - Learn how Studio workflows are organized. * [Erase Objects ](/features/studio/object-eraser-tool.md)- Remove unwanted objects from clips under 5 seconds. * [Rotoscope](/features/studio/sam-3-rotoscoping.md) - Keep a subject and remove the background. * [Add Effects](/features/studio/kling-vfx.md) - Add VFX, weather, lighting, or style. * [Relight Scene](/features/studio/relight-scene.md) - Change lighting or mood. * [Upscale](/features/studio/video-upscaling.md) - Improve resolution after retakes or generation. *** **Next:** If you need to remove a clearly selected object from a very short clip, use Erase Objects.
