# Transition Mode {% hint style="info" %} **Two images attached and want Reference Mode instead?** By default, attaching 2 images activates **Transition Mode** (start frame → end frame morph). If you want those 2 images treated as **reference photos of a character** instead, switch to a reference model: **Kling O3 Reference**, **Seedance 2 Reference**, or **Wan 2.7 Reference** — these models treat multiple images as subject references, not as start/end frames. {% endhint %} ### How It Works 1. **Enable Generate Media** - Toggle the Generate Media button in the composer 2. **Attach two images** - Upload or drag & drop exactly two images 3. **Transition Mode activates** - The system automatically detects two images 4. **Model auto-switches** - Compatible transition models appear in the selector 5. **Describe the transition** - Write a prompt describing the motion between frames 6. **Configure settings** - Set duration (may be locked based on model) 7. **Generate** - Click send to create the transition ### Automatic Activation When you attach **exactly two images**, Transition Mode activates automatically: * **Model selector updates** - Shows only transition-compatible models * **Duration may lock** - Some models have fixed durations for transitions * **Aspect ratio auto-detects** - Matches your source images * **Prompt field appears** - Ready for transition description ### Supported Models Not all models support transitions. Here are the models that do:

Wan 2.72-15s16:9, 9:16, 1:1, 4:3, 3:4❌High-resolution start-to-end interpolation
> **Note:** Kling 3.0 models are **universal** — they support Text-to-Video (0 images), Image-to-Video (1 image), and Transition Mode (2 images). Kling O3 Transition is a **dedicated** transition model with superior morphing quality and a Pro/Standard quality toggle. Seedance 2 and Wan 2.7 both auto-detect transition mode when two images are attached — no manual switching required. ### Writing Transition Prompts #### What to Describe Focus on **how the scene transforms** from the first image to the second: 1. **Transformation type** - Morph, dissolve, pan, zoom, etc. 2. **Motion path** - How elements move between frames 3. **Timing** - Fast, slow, gradual, sudden 4. **Visual style** - Smooth, cinematic, dynamic, etc. #### Good Transition Prompts ✅ **Morphing:** ``` Smooth morphing transition where the first scene gradually transforms into the second, with elements flowing and blending naturally ``` ✅ **Camera Movement:** ``` A cinematic camera pan that reveals the transition from the first scene to the second, with smooth motion and natural flow ``` ✅ **Environmental:** ``` Gradual transition where the environment shifts from day to night, with lighting and atmosphere smoothly changing between the two scenes ``` ✅ **Object Transformation:** ``` The object in the first frame smoothly transforms and moves into the position shown in the second frame, with natural motion and physics ``` #### Bad Transition Prompts ❌ **Too Vague:** ``` Transition between two images ``` *(Not specific enough)* ❌ **Describes Images, Not Motion:** ``` A coffee shop and then a beach ``` *(Missing transition description)* ❌ **No Motion:** ``` Two different scenes ``` *(Doesn't describe the transition)* ### Aspect Ratio Matching #### Important: Both Images Must Match **Critical requirement:** Both images should have the **same aspect ratio** * ✅ **Both 16:9** → Works perfectly * ✅ **Both 9:16** → Works perfectly * ✅ **Both 1:1** → Works perfectly * ❌ **16:9 + 9:16** → May cause issues * ❌ **Different ratios** → May crop or distort **Why this matters:** * The transition needs consistent framing * Mismatched ratios can cause cropping * Auto aspect ratio uses the first image's ratio ### Use Cases #### Scene Transitions **Example:** * Image 1: Interior coffee shop * Image 2: Exterior street view * Prompt: "Smooth camera push through the window, transitioning from the cozy interior to the bustling street outside." * Result: Cinematic scene transition #### Time Transitions **Example:** * Image 1: Daytime landscape * Image 2: Nighttime, same location * Prompt: "Gradual time-lapse transition from day to night, with lighting and colors smoothly shifting." * Result: Time transition video #### Object Morphing **Example:** * Image 1: Seedling * Image 2: Full-grown tree * Prompt: "Time-lapse morph showing the seedling growing into the mature tree, with smooth transformation." * Result: Growth animation #### Location Transitions **Example:** * Image 1: Urban cityscape * Image 2: Mountain range * Prompt: "Cinematic camera pull-back revealing the transition from city to nature, with smooth motion." * Result: Location transition ### Model-Specific Behavior #### Veo 3.1 / Veo 3.1 Fast **Characteristics:** * Duration: 4s, 6s, or 8s (your choice) * Aspect ratio: Auto (matches first image) * Audio: Supported (if enabled) * Quality: High, smooth transitions **Best for:** * Smooth, cinematic transitions * When you need audio * Variable duration needs #### Veo 3.1 Lite **Characteristics:** * Same **two-image** transition workflow as other Veo 3.1 models (first / last frame) * Duration: 4s, 6s, or 8s * **No** generated audio — add music or SFX in Premiere * Resolution: **720p or 1080p** only **Best for:** * Cost-sensitive transition tests and previews * When you will handle all sound in the edit #### Kling O3 Transition (Pro / Standard) **Characteristics:** * Duration: Flexible (3-15 seconds) * Aspect ratio: Auto-detected from input images * Audio: Supported (native audio generation) * Quality: Best morphing quality with character consistency * Pro/Standard quality toggle **Best for:** * Highest quality transitions * Superior morphing with minimal hallucination * Character consistency between frames #### Kling 3.0 Pro / Standard **Characteristics:** * Duration: Flexible (3-15 seconds) * Aspect ratio: 16:9, 9:16, or 1:1 * Audio: Supported (native audio generation) * Quality: Excellent, with element support **Best for:** * High-quality transitions with audio * Flexible duration control * Universal workflow (same model for T2V, I2V, and transitions) * Element support for character consistency via @Element tags #### Seedance 2 **Characteristics:** * Duration: 4-15 seconds (auto default) * Aspect ratio: Auto-detected from input images * Audio: Supported (native audio generation, default on) * Resolution: 480p-1080p * Quality: Natural, cinematic motion **Best for:** * Transitions that need a soundtrack * Natural flowing motion between frames * When you want audio generated automatically #### Wan 2.7 **Characteristics:** * Duration: 2-15 seconds * Aspect ratio: 16:9, 9:16, 1:1, 4:3, or 3:4 * Audio: Not supported * Resolution: 720p-1080p * Quality: High resolution start-to-end interpolation **Best for:** * High-resolution transitions up to 1080p * Start-to-end frame interpolation * When you need more aspect ratio options ### Tips for Best Results 1. **Match aspect ratios** - Both images should have the same ratio 2. **Use high-quality images** - Better sources = better transitions 3. **Be specific about motion** - Describe how the transition happens 4. **Consider composition** - Ensure both images work together visually 5. **Test different models** - Veo for audio, Kling for quality 6. **Keep prompts focused** - Describe the transition, not the images 7. **Plan your frames** - Think about how they connect visually ### Common Workflows #### Quick Transition 1.
