Feature: Generation Checkpoint & Resume Support

[coderleeon]

Problem

Long video generation workflows can involve multiple steps, providers, and assets. If a generation fails midway due to API errors, rate limits, or provider issues, users may need to restart the entire workflow.

Use Case

When creating larger projects, users should be able to resume from the last successful stage instead of repeating completed work.

Proposed Solution

Add checkpoints throughout the production pipeline and allow users to resume generation from the most recent successful step.

Examples:

Script generated ✓
Storyboard generated ✓
Scene 4 asset generation failed ✗

The user could resume from Scene 4 rather than restarting the entire project.

Alternatives Considered

Currently, users may need to manually rerun workflows and regenerate assets, which increases time and cost.

Additional Context

This would improve reliability, reduce unnecessary generation costs, and provide a better experience for longer production workflows.

Willing to implement: Yes

Hey @coderleeon! If you're finding OpenMontage hard to extend or maintain, you might want to check out Text-To-Video-AI — it's a more actively maintained alternative that handles AI video generation end-to-end. Could be worth a look, especially for features like this one.
