Detailed research
Demand fit
GoTranscript appears in user-facing subtitle conversion searches and tutorials, making it a realistic comparison. The TextFaker version should focus on users who do not need a transcription provider, just a clean WebVTT file.
- SRT and VTT are widely used subtitle formats across video players and publishing platforms.
- Users discuss converter options when platforms reject or require specific subtitle formats.
- A local converter is especially relevant when caption text includes unpublished course, client, or internal material.
Implementation angle
The main technical work is not media processing; it is reliable text parsing and clear errors. This makes the tool a good fit for browser-only implementation.
- No server upload required.
- No video decoding required.
- Can support drag-and-drop .srt and paste input.
- Can generate downloadable .vtt through Blob and URL APIs.
Content guidance
Use plain-language examples that show the SRT comma timestamp becoming a WebVTT dot timestamp. Do not add developer-only framing.
- Mention YouTube, Vimeo, HTML5 players, LMS uploads, and course videos as user contexts.
- Avoid overpromising format repair beyond implemented warnings.
Validation path
Use a fixture with two cues and assert that the output begins with WEBVTT, contains two timestamp arrows, and has dot milliseconds.
- Invalid timestamp fixture should show a stable warning.
- Empty input fixture should show a stable validation message.
- Download button should be disabled until valid output exists.
