Frameflow

A five-stage pipeline for UGC-style video ads

Services: AI Workflow Automation ; AI Agents
Delivery: Video-generation application and AWS orchestration infrastructure. Portfolio alias.

Producing one video involved several AI services. An image had to reach the video provider, the script had to reach speech generation, and the finished video and audio had to reach lip-sync.

The providers did not all finish within one request. A video job could remain active after the user left the page. The application needed to retain the job, recognize the callback, and continue from the correct stage.

The pipeline starts with a reference image and product information. Gemini analyzes the scene and prepares the imagery and script. Kling handles image-to-video generation. Speech generation and Sync.so provide the voice and lip-sync stages.

AWS Step Functions coordinates the sequence. Lambda tasks perform individual actions, DynamoDB stores project and external-job information, and S3 holds media. API Gateway exposes callback routes.

The state machine includes waits for Kling and Sync.so completion, a finalization task, and an error-handling path.

Wait for completion events. The pipeline uses task-token waits for long-running jobs rather than holding an ordinary web request open.

Retain the external job ID. A provider callback needs to resolve to the correct project and stage.

Track failure as part of the workflow. A failed generation must leave a useful project state rather than appearing to run forever.

Keep the cost breakdown visible. Earlier documentation estimates roughly $0.001 for Gemini, $0.50 for Kling, and $0.83 for Sync.so, rounded to about $1.35. Retries, duration, infrastructure, and changing provider rates can alter the actual cost.

The delivered product coordinates the generation stages from input to finalized media. Users do not need to manually move each intermediate output between the providers in that pipeline.

The historical estimate is useful for explaining the original unit-cost design. It is not presented as a current price guarantee or evidence that the videos increased ad conversions.

Frameflow connects five creative stages through an AWS pipeline with provider callbacks and tracked jobs. The documented configuration targets ten-second videos; its historical provider-cost estimate was about $1.35 per output.

We built the pipeline behind the video generator: scene analysis, imagery, script, video, and voice sync. The work included waiting for provider jobs, matching callbacks to projects, and handling failures between stages.
