What is tracing for video generation?
A trace is the top-level record for a single instrumented workflow. Spans inside the trace represent timed segments such as a fal model call, preprocessing, or upload.
Traces beside artifacts
Generic observability tools optimize for tokens. Video teams need the clip next to the span that produced it — otherwise debugging is guesswork across storage URLs and logs.
Frametail exports spans from fal and other providers into a trace viewer built for generative video.
From trace to benchmark
Sample interesting production traces into datasets, or debug a regression in staging before you pin rows for a benchmark. Traces explain *what happened*; benchmarks prove *whether it got better*.
