π Step-by-Step Tutorial
Step 1: Initialize the Botanical Time-Lapse Master Prompt in ChatGPT [Timestamp: 00:01:13]
Open ChatGPT and paste the complete Time Lapse Plant Growth Master Prompt into the chat. When prompted with What plant growth concept would you like to create?, respond with your chosen plant or seed (e.g., Mango seed or Cucumber). ChatGPT builds the complete production systemβlocking the Plant DNA, World Bible, and lighting conditionsβand generates three precise 10-second prompts representing the continuous 30-second growth progression.

The final video must feel like ONE CONTINUOUS BOTANICAL TIME-LAPSE EVENT.
02 β FIRST RESPONSE RULE
When this Master Prompt is given:
If the user has NOT provided a plant type or concept:
Your ONLY first response must be:
What plant growth concept would you like to create?
If the user HAS provided a plant type or concept:
Skip the question.
Proceed directly to the complete production workflow.
Do NOT summarize this prompt.
Do NOT explain it.
Just activate and ask β or proceed.
03 β NICHE UNDERSTANDING: TIME-LAPSE PLANT GROWTH
Core visual mechanisms:
GERMINATION
Seed cracks
First root emerges
ROOT GROWTH
Primary root extends
Secondary roots branch
Fine root hairs develop
STEM RISE
Shoot pushes through soil
Stem elongates upward
LEAF UNFURLING
Cotyledons / first leaves open
Leaves expand
Plant reaches toward light
MATURE FORM
Plant develops its characteristic structure
Flowering or fruiting when biologically appropriate
The visual result must resemble a photorealistic accelerated botanical observation.
CRITICAL MODEL REALITY
The model is generating a visual simulation of time-lapse growth, not scientifically accurate real-time biological footage.
Therefore:
Prompt for the illusion of accelerated natural growth
Make growth visibly progressive
Keep transitions smooth
Avoid magical transformations
Avoid instant teleportation of plant structures
Avoid unrealistic morphing
Preserve biological directionality
The final 30-second video must communicate:

09 β CLIP PROMPT TEMPLATE
For each 10-second generation unit, output:
CLIP [N] β [TIME RANGE]
START STATE
Describe the exact visual state inherited from the previous clip.
PROMPT
Write a complete Google Omni 1.1 Flash optimized prompt containing:
Subject
Species
Environment
Camera
Composition
Lighting
Current biological state
Accelerated growth behavior
Physical realism
Time-lapse illusion
Continuity instructions
End-state requirement
ACTION TIMELINE
0β2s β Growth action
2β4s β Growth action
4β6s β Growth action
6β8s β Growth action
8β10s β Growth action
CAMERA
Specify exact camera behavior.
GROWTH STATE
Describe progression from beginning to end.
ENVIRONMENT
Describe all stable environmental elements.
LIGHTING
Describe continuity requirements.
AUDIO
Describe sound design.
END STATE
Describe the exact state at 10 seconds.
NEXT CLIP HANDOFF
Describe exactly what Clip N+1 must inherit.
10 β SCENE EXTENSION / CONTINUATION WORKFLOW
The preferred workflow is:
STEP 1
Generate Clip 01 β EXACT 10 seconds.
STEP 2
Use the generated Clip 01 as the source for continuation / scene extension.
STEP 3
Extend into Clip 02 β EXACT 10 seconds.
The continuation instruction must explicitly tell the model:
Continue the exact same botanical scene naturally from the final moment of the previous clip. Preserve the existing plant, seed, roots, soil, container, camera perspective, lighting direction, background and visual style. Do not restart or regenerate the plant. Continue its biological growth from its current state.
STEP 4
Continue Clip 02 into Clip 03 β EXACT 10 seconds.
Use the same continuity principle.
CRITICAL CONTINUATION RULE
Every new 10-second clip must begin from the actual visual state of the previous clip.
Never describe Clip 02 as if the seed is starting again.
Never describe Clip 03 as if the plant is newly planted.
The sequence must be:
Clip 01 END β Clip 02 START
and
Clip 02 END β Clip 03 START
with no visible reset.
11 β 10-SECOND CLIP CONTINUITY RULE
Because each generation unit is exactly 10 seconds:
FIRST 9 SECONDS
Growth and progression.
FINAL 1 SECOND
Relative stabilization.
The final second should:
Avoid sudden camera movement
Avoid extreme growth acceleration
Keep the plant clearly visible
Maintain stable composition
Prepare a clean visual handoff
This makes the transition into the next 10-second generation unit more coherent.
12 β NEGATIVE CONSTRAINTS
The model MUST NOT create:
Plant identity drift
Species changes
Environment redesign
Container changes
Soil color changes
Background changes
Lighting discontinuity
Camera reset
Perspective reset
Plant duplication
Multiple plants unless intentionally specified
Growth regression
Smaller plant after continuation
Seed regeneration
Root disappearance
Leaf disappearance without biological reason
Magical growth
Instant morphing
Teleportation
Random time jumps
Sudden cuts
Unrealistic anatomy
Impossible root direction
Roots growing upward without reason
Stem growing downward
Leaves appearing randomly
Unnatural camera movements
13 β ASPECT RATIO ADAPTATION
FORMAT: 9:16 vertical.
COMPOSITION
Keep the plant visually dominant.
The vertical composition must accommodate:
ROOT ZONE
β
SOIL LINE
β
STEM
β
LEAVES / MATURE CANOPY
For transparent soil cross-section:
Underground growth remains readable
Above-ground growth remains readable
Plant remains centered
PLATFORM SAFETY
Keep important visual information away from:
Top 15%
Bottom 20%
This protects the subject from Shorts / Reels / TikTok interface overlays.

Duration: 10 seconds
Speed: 1x
Step 3: Render Clip 01 and Capture the Final Frame [Timestamp: 00:02:27]
Copy the Clip 01 prompt generated by ChatGPT (covering 00:00β00:10: Seed activation, shell cracking, and primary root emergence). Paste the prompt into the Google Flow prompt box and click enter to generate the initial 10-second video. Once generation is complete, drag the playhead directly to the final frame (at 00:10) and click Save Frame.
Step 4: Chain and Render Clip 02 [Timestamp: 00:02:55]
Navigate to All Media, click the three-dot menu on the newly saved freeze frame, and select Add to prompt. This sets the exact ending state of Clip 01 as the starting canvas for Clip 02. Copy the second prompt from ChatGPT (covering 00:10β00:20: Secondary root branching, root network expansion, and shoot emergence through the soil surface) and paste it into Google Flow. Hit enter to generate the second 10-second clip.
Step 5: Chain and Render Clip 03 for the Final Payoff [Timestamp: 00:03:18]
Move the playhead to the last frame of the newly rendered Clip 02, click Save Frame, go to Media, tap the three dots, and select Add to prompt. Copy the Clip 03 prompt from ChatGPT (covering 00:20β00:30: Stem elongation, leaf unfurling, and full mature plant canopy) and paste it into the generator. Click enter to render the final 10-second sequence.
Step 6: Assemble, Preview, and Export the Full 30-Second Time-Lapse [Timestamp: 00:03:49]
Once all three 10-second clips are generated, stay inside Google Flow to merge them seamlessly. Select your first clip, click Add to clip, select the second clip, click Add media, and append the third clip in sequential order along the timeline. Preview the stitched playback to verify smooth root branching and shoot growth across all transitions. Finally, click the Done button in the top-right corner to download the completed 30-second vertical time-lapse video.

π‘ Key Takeaways & Pro Tips
- Save the Exact Last Frame: Never generate each clip from scratch using only text prompts. Always capture the final frame of the previous clip and use Add to prompt to preserve the identical glass container, soil density, root positions, and lighting angle.
- Enforce the 10-Second Generation Unit: Omni Flash produces its most stable, coherent biological physics in 10-second segments. Structuring the complete lifecycle into three 10-second blocks (10s germination, 10s root/shoot rise, 10s leaf/mature payoff) ensures natural pacing and algorithmic virality for Shorts and Reels.
- Transparent Glass Cross-Section Setup: Setting the environment to a transparent glass soil cross-section lets the viewer observe simultaneous underground root branching and upward shoot elongation, creating high visual fascination and watch time.
