Tool Limitations: Resolution, Length, and Credit Costs

Tool limitations: resolution, length, and credit costs

Written by Runbo (CEO of Magic Hour)

Overview

Each Magic Hour tool has specific limits based on your subscription plan. Limitations include maximum output resolution, video length or frame count, and the credit cost per generation. Always check the credit estimate shown in the Magic Hour UI before generating — it shows the exact cost for your specific settings (model, resolution, duration, audio, etc.).

Video Generation Tools

Credit costs for video tools are calculated as: frames × FPS-based multiplier × per-model cost multiplier. The multiplier varies by model, resolution, and whether audio is enabled. Always check the UI estimate before rendering.

Understanding Credit Costs

Cost Multipliers

Video tools with higher processing complexity use a higher cost multiplier. For Text-to-Video and Image-to-Video, the multiplier also depends on the AI model and resolution selected — some premium models at high resolution with audio can reach 6× or more per frame.

Pro tip: Before generating, check the credit estimate shown in the Magic Hour UI. This displays the exact credit cost for your specific settings before you commit.

Plan-Based Resolution Limits

Your subscription plan determines the maximum output resolution available for each tool:

Plan

Max Resolution

Free (Basic)

576px

Creator

1024px

Pro

1472px

Business

4096px (4K)

If you attempt to generate at a resolution not available on your plan, the tool will either downscale the output or prompt you to upgrade.


Frame and Duration Limits Explained

How Frames and Duration Relate

Video tools work with frames. Duration depends on the frame rate (FPS) of the specific model:

Formula: Duration (seconds) = Frames ÷ Frame Rate (FPS)

Frame rates vary by model (typically 16, 24, or 30 fps). Examples:

  • Face Swap with max 100,000 frames at 30 fps → ~3,333 seconds (~55 minutes)

  • Lip Sync with max 120,000 frames at 24 fps → ~83 minutes

  • Text-to-Video with max 2,000 frames at 30 fps → ~67 seconds

  • Animation with max 10,000 frames → up to ~333–417 seconds depending on model FPS


Input File Limitations

Upload Size Limits

Maximum file sizes for inputs vary by plan:

Plan

Max Upload Size

Free (Basic)

200 MB

Creator

2 GB

Pro

5 GB

Business

10 GB


Credit Balance and Insufficient Credits

If you attempt to generate content but don't have enough credits, the generation will not start and you will not be charged. Check your credit balance before generating, especially for longer or higher-resolution video tools.

Your credit balance is visible in the top-right corner of the dashboard. If you run out of credits:

  • Purchase additional credits with a Credit Pack

  • Upgrade to a subscription plan that includes more credits

  • Reduce your generation settings to lower the credit cost

Credits never expire. Unused credits from subscriptions and credit packs carry over indefinitely — they do not reset between billing cycles.


Exceeding Limitations

What Happens If You Exceed Limits

Limit Exceeded

What Happens

Resolution too high for your plan

Output is downscaled to your plan's maximum, or generation is blocked

Duration or frames too long

Generation is blocked; shorten your input or upgrade your plan

Insufficient credits

Generation does not start; purchase credits or adjust settings

Upgrading to Remove Limitations

To access higher resolutions, longer durations, or larger file uploads, upgrade your plan at magichour.ai/pricing. New limits take effect immediately.
