Competitor Research: Study “Viking Chronicles” First
We need to look at what a successful competitor is doing.
From the script, the competitor is:
- Channel name: Viking Chronicles
- Videos uploaded: 52
- Subscribers: 11.6k
- Channel age: about 1–1.5 months
- Total views: 700K
- Video length: 27–39 minutes (around 30 minutes average)
- Upload rate: 4 videos per week
- Thumbnails: simple, clean, eye-catching
- Growth: strong weekly views
Channel Data as on 15 December,2025
What we learn:
- Long-form documentary content is working.
- Simple thumbnails + strong titles = clicks.
- Consistency drives growth.
Fix Your Content Format for Viking Documentary YouTube Automation
We need to lock a clear format before production.
Recommended format (based on the script):
- Video length: 30 minutes
- Upload frequency: 4 videos/week
- Voice style: calm and deep documentary narration
- Structure: story-based scenes (around 8 seconds each)
Generate Titles (ChatGPT Prompt Method)
We need a title that feels like a documentary and gets a high CTR.
Process:
- We paste the title prompt in ChatGPT.
- We get 5 title ideas.
- We select the best title.
Examples from the script:
- How Vikings Survived the Long Dark Winter Without Modern Help
- The Secret Behind Viking Winter Survival in Extreme Cold
- How Ancient Vikings Stored Food and Endured Frozen Seasons
We should pick a title that:
- is clear
- creates curiosity
- uses strong keywords like “Vikings,” “winter,” “survival”
Script Writing: Create a 30-Minute Documentary in Parts
We won’t get a full 30-minute script in one go.
We need to generate it in parts.
Process:
- We paste the script prompt.
- We add our selected title where it says “Insert Title.”
- ChatGPT generates the script in parts (Part 1, Part 2, Part 3).
Then we copy each part and use it in the next step.
Voiceover: Use a Calm, Deep Voice
Documentaries need a deep and calm voice.
Process (as shown in the script):
- We open a VO tool (example mentioned: MicMaster).
- We select a deep, calm voice.
- We generate Part 1.
- We generate Part 2.
- We generate Part 3.
Now our voiceover is ready.
Visuals: Convert the Script into Scene Prompts (VEO3 Prompts)
Now we need visuals.
Process:
- We copy the “Video Prompt.”
- We paste the full script where it says “Insert Script.”
- ChatGPT creates scene-by-scene prompts.
From the script:
- 1 scene = about 8 seconds
- 30 minutes = around 180–200 scenes (approx)
We keep typing “Continue” to generate the next batch of scenes until everything is complete.
Text-to-Video Generation: Use the Right Settings
We paste each scene prompt into a text-to-video tool (the script mentions using Flow).
Recommended settings:
- Format: Landscape 16:9
- Model: VEO3
- Fast mode = cheaper (uses fewer credits)
- Quality mode = best output (uses more credits)
Important:
Sometimes the tool adds dialogue/voice automatically.
We need to remove the “script line” from the prompt and keep it no dialogue.
Then we:
- generate the scene
- download it
- rename it (01, 02, 03… or Scene 1, Scene 2…)
Edit in Filmora: Simple Workflow
Editing should stay simple and efficient.
Steps:
- We open Filmora.
- We import all scene clips.
- We import the voiceover audio.
- We place the voiceover first on the timeline.
- We match clips scene-by-scene with the voiceover.
Tip:
Each scene prompt includes a script line.
We listen to the VO and place the correct scene for that line.
Fix the Sound: Smooth Documentary Feel
We don’t want harsh audio jumps.
We do this:
- set each clip volume to around -10
- apply Fade In + Fade Out (2–5 seconds)
This makes transitions smooth.
Add Background Music
We need calm documentary-style music.
Process:
- We download a track from a free music site (the script suggests searching “calm” or “documentary”).
- We keep the music low (around -10 to -15).
- We add a fade out at the end.
Goal:
- music supports the mood
- voice stays clear
Thumbnail Prompts: Create Clickable Options
We need thumbnails similar to the competitor’s style.
Process:
- We copy the thumbnail prompt.
- We paste it into ChatGPT.
- We add our final title.
- We get 4–5 thumbnail prompts.
- We generate thumbnails and pick the best one.
Keep it simple but highly clickable.
YouTube SEO Pack: Title, Description, Hashtags, Tags
Now we prepare SEO for upload.
Process:
- We paste the SEO prompt in ChatGPT.
- We add our final title.
- ChatGPT generates:
- high CTR title options
- description with hashtags
- tags list
Tag tip:
Paste tags with commas into the YouTube tags section.
