JAMD Microscopic Video Editor helps you prepare the case video required for certification by the Japan Association of Microscopic Dentistry (JAMD) — Certified Dentist and Certified Dental Hygienist — entirely on your iPhone.
WHY THIS APP EXISTS
General-purpose video apps make it easy to add something a certification case video is not meant to contain. Stabilization, a crop, a speed change or a transition can be applied in a single tap — often without the applicant ever intending it. This app takes a different approach: rather than warning you afterwards, it simply does not implement those operations. Cutting, subtitles and title cards are all there is. You do not need to memorize the editing rules; a video that breaks them cannot be produced.
WHAT YOU CAN DO
- Two modes
Certified Dentist: one case, 180-300 seconds of case footage.
Certified Dental Hygienist: one Required Task video (90-120 seconds) plus two Free Task videos (up to 90 seconds each), joined automatically into one video (fiscal 2027 rules).
Choosing a mode applies the submission rules automatically.
- Cut editing
Select only the parts you need. The timeline plays back the finished video itself, so you can split, delete and trim while seeing exactly what will be exported.
- Subtitles
Overlay procedure names or commentary. Font size and position (top / middle / bottom) are adjustable. You can also type them all at once in a list view.
- Title cards
Enter the applicant name and case title, and a rule-compliant title card (3 seconds each) is generated automatically.
- Preflight check
Before export, the app verifies resolution, frame rate, length and subtitle placement. If any rule is not met, export is blocked and the problem is shown.
- Silent export
The submission rules require no audio, so every audio track is removed automatically.
- Edit log
A JSON record is generated alongside the video. It stores only which source was used, from what second to what second. There is no field in which a scale factor or a speed factor could be written, so the record itself shows that out-of-spec processing could not have entered.
(This records what was done inside this app. It does not determine whether the source video was processed before import.)
- Four languages
Japanese / English / Korean / Traditional Chinese

PRIVACY
All video data is processed on your device. The app has no networking capability, so nothing is ever uploaded to any server.
