3. Working with Subtitles
- Subtitle Files: Often in
.srt,.vtt, or.assformats. - Adding/Extracting Subtitles: Software like VLC, FFmpeg, or dedicated subtitle editors can be used.
8. Risks & Mitigations
| Risk | Impact | Mitigation | |------|--------|------------| | Large batch (100 × 10 MB) overwhelms server memory. | Crash / OOM. | Use streaming processing, limit concurrent workers, enforce per‑file size cap. | | Incorrect offset sign (user expects negative but UI defaults to positive). | Wrong subtitles, user frustration. | Add explicit +/- toggle and tooltip explaining sign. | | Subtitle files with malformed timestamps. | Conversion fails for entire batch. | Validate each file individually; skip only the faulty file and report it. | | Browser compatibility for large file uploads. | Users on older browsers can’t use the feature. | Show graceful fallback message, encourage modern browsers. | | Temporary files left on disk (security). | Data leakage. | Automated deletion after response or after 15 min via a cleanup cron job. | JUQ-968-engsub Convert02-23-49 Min
4. Acceptance Criteria
| # | Given | When | Then |
|---|-------|------|------|
| AC‑1 | The user is on the “EngSub Convert” page | They upload one or more subtitle files and click Convert | The system validates each file (correct extension, well‑formed timestamps) and returns an error list for any invalid file, aborting processing for those files only. |
| AC‑2 | The offset field is empty | The user clicks the “02:23:49 Min” shortcut button | The field is auto‑filled with 02:23:49 and the UI shows “+2 h 23 m 49 s”. |
| AC‑3 | The user selects .srt as source and .vtt as target | Conversion runs | All timestamps are shifted, the file is rewritten in VTT syntax, and the download name changes to <original‑name>.vtt. |
| AC‑4 | Any subtitle line after shifting would become negative (e.g., original 00:00:02 shifted by –00:00:05) | The conversion runs | The system clamps the timestamp to 00:00:00 and flags the line in the preview log with a warning. |
| AC‑5 | The user uploads ≥ 1 and ≤ 100 files | The conversion starts | A progress bar shows “Processing X of Y files”, and a Cancel button aborts remaining work while preserving already processed outputs. |
| AC‑6 | The conversion finishes successfully | The UI shows Download All (ZIP) and Download Log (CSV) buttons | Clicking either triggers a file‑download with correct MIME types (application/zip, text/csv). |
| AC‑7 | The user clicks Preview before conversion | The system displays the first 5 subtitle entries after applying the offset (but before format conversion) | The preview table includes original timestamp, new timestamp, and subtitle text. |
| AC‑8 | The user has an invalid file (e.g., .txt) | They attempt to process it | The UI shows a clear error “Unsupported file type – only .srt, .vtt, .ass are allowed.” |
| AC‑9 | The user’s browser is IE11 (unsupported) | They load the page | The UI displays a friendly “Your browser is not supported – please use Chrome, Edge, or Firefox.” |
| AC‑10 | The conversion is completed | The server cleans up temporary files | No processed files remain on the server after 15 minutes or after the user downloads, whichever comes first. | It is written as a self‑contained document that
Part 7: Ethical Considerations – Supporting Creators
While the technical act of converting a video and adding subtitles is neutral, distributing copyrighted material without compensation harms the creators, actors, and studios. Subtitle Files : Often in
Steps to Consider
- Identify the Source: Ensure the video content you're seeking is available from a legitimate source.
- Subtitle Support: If your query involves subtitles, check if the video player or platform you're using supports external subtitles or has built-in subtitle support.
- Video Conversion: For conversion queries, tools like HandBrake, FFmpeg, or online converters might be useful. These tools can help convert video formats and sometimes integrate subtitles.
Step 3: Name Your Output File
A clear, organized name might be:
JUQ-968 [English Subtitle Personal Copy].mp4
Avoid the “Convert02-23-49 Min” style unless it helps your personal filing system.
