VIDEO TIMING ANALYSIS
Video Frame Drop Detector
Find candidate timestamp gaps in supported MP4 tables or supplied timing lists. Review intentional VFR changes separately.
WORKED EXAMPLE
Frame monitor
Input, export & project notes
Projects save editable content, controls and source fingerprints. Original binary files remain on your device; reselect them after reopening to regenerate media-dependent results. Downloads may include a bounded proof rather than the full original. Review the method and export labels before delivery.
Using Video Frame Drop Detector
Find candidate timestamp gaps in supported MP4 tables or supplied timing lists. Review intentional VFR changes separately.
- Start with Try example to see the video frame drop detector workflow. Use the worked sample frames, or choose browser-decodable footage. Capture controls limit the selected sample to 12 seconds, 120 frames and a 640-pixel long edge. Container inspection uses nonfragmented MP4/MOV sample tables or explicitly supplied evidence.
- Use the nearby controls and editable records, then choose the main update button. Undo/redo restores content and settings; keep source media to regenerate file-dependent projects.
- Review the preview, Evidence and Review tabs. User-entered evidence is not a decoded container inspection. Timestamp gaps can be intentional VFR; decoded duplicate pictures are a separate check.
- Choose Export for the actual task files, report JSON/CSV or the complete ZIP. Save project retains editable content and control settings. Original binary media is not embedded; source fingerprints help identify the files needed when reopening.
Example
The tailored example produces 11 evidence records. User-entered evidence is not a decoded container inspection. Timestamp gaps can be intentional VFR; decoded duplicate pictures are a separate check.
Questions & answers
What does Video Frame Drop Detector do?
Find candidate timestamp gaps in supported MP4 tables or supplied timing lists. Review intentional VFR changes separately. User-entered evidence is not a decoded container inspection. Timestamp gaps can be intentional VFR; decoded duplicate pictures are a separate check.
What can I open?
Use the worked sample frames, or choose browser-decodable footage. Capture controls limit the selected sample to 12 seconds, 120 frames and a 640-pixel long edge. Container inspection uses nonfragmented MP4/MOV sample tables or explicitly supplied evidence.
What can I download?
The Export tab lists actual artifacts generated by the current input. A complete ZIP includes task files, evidence, editable content and method notes. Audio processing produces PCM WAV where applicable; music utilities add MIDI or practice WAV; frame workflows include PNG frames and an optional silent, sampled WebM proof. Graphic outputs may include SVG/HTML, and geometry workflows disclose supported OBJ/STL/PLY outputs.
What should I check before using the result?
User-entered evidence is not a decoded container inspection. Timestamp gaps can be intentional VFR; decoded duplicate pictures are a separate check. Inspect the export in its intended player, engine, editor, printer or delivery workflow. Findings are scoped checks, not certification. Processing stays in the browser; the public site retains approved advertising and optional consent-based analytics.
