- Validate source files against MIME/signature before conversion.
- Run conversion on representative fixture sizes from the sample library.
- Verify output format integrity, metadata, and playback/rendering behavior.
- Benchmark throughput and resource cost before production rollout.
Matriz de compatibilidade
| Aspecto | SRT Source | VTT Target | Foco de validacao |
|---|---|---|---|
| Decoder/Parser Support | Player support varies by subtitle format and styling features. | Player support varies by subtitle format and styling features. | Test representative clients and parser libraries before rollout. |
| Metadata & Structure | Timing and style attributes can drift after conversion. | Timing and style attributes can drift after conversion. | Compare metadata fields before and after conversion for drift. |
| Compression & Payload | Payloads are small; integrity is more important than compression. | Payloads are small; integrity is more important than compression. | Benchmark output size, quality, and processing cost at multiple settings. |
Padroes comuns de falha
- Converting malformed SRT files without pre-validation causes inconsistent outputs.
- Assuming all VTT readers parse metadata identically creates production regressions.
- Skipping fixture size diversity leads to blind spots in memory and throughput behavior.
- Deploying conversion changes without rollback thresholds increases incident risk.
Checklist de QA antes do rollout
1. Validate MIME/signature for incoming SRT fixtures.
2. Run conversion against small, medium, and large SRT samples.
3. Verify structural integrity of generated VTT output.
4. Confirm metadata parity (timestamps, labels, embedded fields).
5. Benchmark conversion latency and resource usage under load.
6. Document fallback path and rollback trigger thresholds.
