A failure is usually shown with which stage stopped, for example before training or during structure-from-motion. That hint tells you if the source data was the problem.
Next steps
- Early failure. Re-export with a supported codec, more stable motion, or better light.
- Mid-pipeline. Try fewer moving objects, more overlap, or a shorter clip to prove the path works.
- Retry once. If it was a transient server error, a single re-upload can succeed.
