Creating Better Videos
What makes a good video prompt?
Good video prompts are descriptive and specific. Include details about:
- Lighting: "golden hour", "soft lighting", "dramatic shadows"
- Style: "cinematic", "anime style", "realistic", "artistic"
- Setting: "peaceful beach", "bustling city", "cozy cabin"
- Action: "birds flying", "waves crashing", "people walking"
- Mood: "serene", "energetic", "mysterious"
Example of a good prompt:
"A majestic eagle soaring through golden clouds at sunset, cinematic style with soft lighting"
What video length and resolution should I choose?
Choose based on your intended use:
For Social Media:
- TikTok/Instagram Stories: 180x320 or 360x640, 15-30 seconds
- YouTube Shorts: 360x640 or 540x960, 15-60 seconds
- Instagram Posts: 540x960, 15-30 seconds
For Professional Use:
- Marketing videos: 540x960, 30-60 seconds
- Product demos: 360x640 or 540x960, 45-60 seconds
Tip: Higher resolution uses more credits but provides better quality.
Why didn't my video turn out as expected?
If your video didn't match expectations, try these improvements:
- Be more specific: Add more descriptive details to your prompt
- Avoid conflicting elements: Don't mix too many different styles or concepts
- Use clear language: Simple, direct descriptions work better than complex sentences
- Try variations: Generate multiple versions with slightly different prompts
- Reference successful examples: Look at featured videos for inspiration
Remember: AI video generation is creative and sometimes unpredictable. Don't hesitate to experiment!
Billing & Credits
How do credits work?
Credits are used to generate videos. The cost depends on duration and resolution:
Credit Cost Formula:
- • 180x320: 1.5 × duration in seconds
- • 360x640: 2.0 × duration in seconds
- • 540x960: 4.0 × duration in seconds
Examples:
- • 10-second video in 180x320 = 15 credits
- • 30-second video in 360x640 = 60 credits
- • 15-second video in 540x960 = 60 credits
What happens if I run out of credits?
When you're low on credits, you have several options:
- Subscribe to a plan: Get monthly credit allowances starting at $10/month
- Wait for renewal: If you're subscribed, credits refresh monthly
- Optimize usage: Use lower resolutions and shorter durations to conserve credits
You can view your current credit balance in the top navigation bar when logged in.
