Document microscopy video as an evidence trail, not just as a polished clip. Record how each scene was captured, preserve the untouched files, log every substantive edit, credit each visual, retain any required releases, and freeze the exact version you submit. Regeneron International Science and Engineering Fair (ISEF) is a useful example, but its rules are not automatically the rules for every science competition. Start with your own fair’s current requirements, then use the workflow below to make your footage reproducible and inspection-ready.
Which rules apply to your competition?
Competition rules have a scope. The Society for Science’s International Rules for Pre-College Science Research hub is the authoritative starting point for ISEF and Society-affiliated fairs, and the current page links to the 2027 Rules and Guidelines. Rules are published annually. An affiliated fair may add requirements, and a local or national competition may use an entirely different handbook. The finalist, adult sponsor, and fair director are responsible for knowing the rules that govern that event.

Use ISEF requirements in this guide as a clearly labeled example. They establish useful practices for visual attribution, releases, digital-display inspection, research plans, and generative-AI disclosure; they do not establish a universal video codec, resolution, frame rate, timestamp format, raw-file submission rule, or edit-log template.

What ISEF’s display rules mean for a project video
The Society for Science Display & Safety Rules say that digital-display materials must be shown in their entirety during inspection. They also state: “These materials may not be altered in any way after the Display & Safety inspection has been completed.” Treat the inspected export, presentation file, and linked media as a locked submission. Do not replace a clip, change a caption, adjust color, or swap the soundtrack afterward.

Set up a documentation system before recording
Create one project folder and one dated lab-notebook or project-log entry before you capture the first frame. A simple structure prevents the common mistake of having a finished video whose origin cannot be reconstructed.
Use a stable folder structure
- 01_raw: original camera files copied from the recording device or capture computer.
- 02_project: the editing project file and any autosave or project-library export.
- 03_working_exports: review copies that are clearly labeled as drafts.
- 04_final: the exact file shown to judges, plus a read-only backup.
- 05_assets: diagrams, still images, narration, music, subtitles, and release documentation references.
- 06_logs: capture sheets, edit records, and a final version note.
Use filenames that sort chronologically, such as 2026-03-14_sample-A_40x_scene-003_raw.mp4. Keep the camera’s original filename in the log if renaming would make the source ambiguous. Make at least two backups on separate storage before deleting anything from a camera card.
Decide what “raw” means for your project
Raw footage is the original clip as written by the camera or capture software, before trimming, speed changes, color adjustments, overlays, compositing, narration, or music. A clip exported from an editor is not raw, even if it looks identical. Copy originals into 01_raw, set them to read-only when practical, and perform all editing on duplicates.

What should you write down when recording through a microscope?
The purpose of a capture log is reproducibility: another person should be able to understand what produced a particular scene. The reviewed ISEF pages do not prescribe a standard camera-settings log, so treat the following as recommended documentation rather than a mandatory form.
Capture-log fields
- Identity: project title or code, operator, and a unique specimen or sample identifier.
- Date and time: include the capture date and, when timing matters, the start time or elapsed time.
- Microscope: manufacturer, model, microscope type, objective magnification, eyepiece or camera port used, and any adapter.
- Camera connection: USB, C-mount, trinocular port, phone adapter, or another interface; record the port or adapter size when relevant.
- Optics and illumination: objective, total magnification if known, transmitted or reflected light, illumination mode, lamp or LED setting, filters, and condenser position.
- Camera settings: resolution, frame rate, exposure or shutter, gain, white balance, focus method, and any automatic mode that materially changed the image.
- Software: capture application and version, operating system, and whether the software applied sharpening, denoising, compression, or automatic color correction.
- Environment: temperature, treatment time, flow rate, or other experimental conditions that affect motion, when those details matter to the claim.
- File reference: original filename, duration, and a short description of what appears in the clip.
Record “automatic” rather than inventing a numeric value when the software controlled a setting. If you change illumination, magnification, focus, or exposure during one recording, mark the time of each change or split the capture into separate clips.

Make the log readable to a judge
Use plain language beside technical values. For example: “Sample A-07, 40× objective, transmitted white LED, USB camera, 1920×1080 at 30 fps, exposure automatic, gain 12, captured 14 March 2026.” Add a short note explaining why a setting changed: “Exposure reduced at 00:18 to prevent the bright edge from clipping.” This connects a visible change in the video to a documented event.
Capture footage that remains scientifically interpretable
- Prepare the specimen and field of view. Confirm the sample identifier, clean the slide or chamber, and allow the specimen to reach the condition being measured. Photograph or sketch the setup in your notebook if orientation will matter later.
- Lock the mechanical setup. Secure the microscope, camera, cables, and stage. A cable tug or accidental focus movement can look like biological motion in the final clip.
- Set a baseline. Focus, choose illumination, and record a short test clip. Check that the subject is visible, highlights are not permanently clipped, and the frame is not being cropped by the capture software.
- Announce changes. If you alter magnification, lighting, treatment, or focus, write it in the log immediately and note the approximate video time.
- Capture more context than the final edit needs. Leave a few seconds before and after an event. Extra handles let you trim without cutting into the transition that proves what happened.
- Verify the file. Open the saved clip on the capture computer before dismantling the setup. Confirm duration, image orientation, audio status, and that the file is stored in the raw folder.
Do not add a scale bar, timestamp, arrow, or false-color treatment during capture unless you understand how the software generates it and record that fact. A label added later is an edit; a scale bar calculated from calibration is a quantitative annotation that should be traceable to the objective and camera setup.

Preserve original clips and document every meaningful edit
Keep the complete original clips even when only a few seconds appear in the competition video. Do not overwrite them with a trimmed export. Give each working copy a version number, such as v01_rough, v02_labels, and v03_inspection. The final export and the editable project file should be separate from both the raw footage and draft renders.
Edit-record fields
- Source filename and the in/out timecodes used.
- Reason for a trim, such as removing setup time or an accidental obstruction.
- Any speed change, loop, freeze frame, reverse playback, or frame interpolation.
- Color, contrast, brightness, sharpening, denoising, stabilization, cropping, or rotation.
- Annotations, scale bars, arrows, labels, compositing, or inserted footage.
- Narration, music, sound effects, subtitles, and the source of each added asset.
- Editor and software/version, export date, resolution, frame rate, and file format.
Speed changes deserve special attention. A two-times clip can make motion easier to see, but it changes the viewer’s sense of time. Display the speed in a caption or narration and keep the original duration in the edit record. A loop or freeze frame must not be presented as continuous observation.
Separate enhancement from evidence
Adjustments that improve legibility are not automatically misleading, but they must not conceal a relevant observation. If you raise contrast, apply a consistent adjustment to comparable samples where possible and state what changed. If a crop removes neighboring structures, identify the crop. Never create movement by duplicating frames, interpolate frames without disclosure, or splice two time periods as though they were continuous.

Do you have to cite microscope photos and graphics?
For ISEF, cite finalist-created graphics individually with the software used and the year created. Graphics made by someone else also require individual citation; an internet-sourced graphic needs its URL. Apply that principle to microscopy stills, extracted video frames, diagrams, labels, plots, and inserted footage instead of placing one vague credit at the end of a long video.
Build a visual-credit list
- Student-created frame: identify it as a microscopy frame, name the capture or editing software, and give the creation year.
- Student-created plot or diagram: name the software used to create it and the year.
- External image or clip: identify the creator or institution when supplied, provide the exact URL, and state any license or permission information required by your fair.
- Modified asset: identify the original source and describe the modification, such as crop, annotation, or color treatment.
Keep the credit close to the visual in the poster, slide, or video end card when space allows. Also maintain a master asset list in your project folder so a judge can connect a credit to a filename. The ISEF guidance does not prescribe a universal citation style for a microscopy video, so follow the fair’s requested style if it provides one.
When are photo or video releases needed?
ISEF requires signed photo/video releases to be kept when a person other than the finalist appears in a photo or video. Keep the signed releases in the notebook and make them available on request; do not display the forms as part of the project. This requirement concerns people shown, not ordinary footage of specimens, cells, or cultures.
The Society’s Display & Safety guidance offers this sample wording: “I consent to the use of visual images (photos, videos, etc.) involving my participation/my child’s participation in this research.” It is sample release text, not a universal required form. Your fair may require different language, a parent or guardian signature, or an institutional form. Obtain permission before recording and retain the completed document with the project records.
Freeze the inspected submission
- Choose a release candidate. Confirm that captions, citations, narration, audio levels, and scientific claims are complete.
- Export once using the fair’s specifications. If no specification exists, retain the editor project and a high-quality master in addition to the playback copy; do not assume a particular codec or frame rate is required by ISEF.
- Review the exported file, not only the timeline. Watch it from beginning to end on the computer or device you will bring. Check missing fonts, black frames, audio drift, unreadable labels, and accidental draft material.
- Record the final identity. Log the filename, file size, duration, export settings, software/version, and export date. Copy it to the
04_finalfolder and a separate backup. - Lock the inspection version. At ISEF, be prepared to show the complete digital presentation. After Display & Safety inspection, do not alter the inspected materials.
Do not infer from the inspection rule that every competition demands your source project file or every raw clip. The reviewed ISEF guidance does not establish a universal source-file submission requirement; provide those materials only when your own fair requests them.

Handle research plans and generative AI separately from video editing
ISEF’s Rules for All Projects include a research plan and ethics requirements. Generative-AI use must be acknowledged, and generative AI may not write the research plan, abstract, poster, or citations. Editing software that trims footage or adds labels is different from using generative AI to author required scientific documents, but disclose any AI use according to the current rules and your fair’s policy.
Keep a short note stating which tool was used, for what limited purpose, and which parts remained your own work. Do not let an AI-generated narration, image, or reconstruction blur the difference between an observed microscope recording and a synthetic illustration; label inserted or generated material clearly.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Choose a microscope camera only when it solves a capture problem
A dedicated microscope camera is optional. A phone adapter, an existing laboratory camera, or a camera already built into the microscope may be sufficient. Buy or borrow hardware only after checking the microscope interface and the computer that will record the video.
Compatibility questions to answer first
- What port or mount does the microscope provide: C-mount, eyepiece tube, trinocular port, or another interface?
- Is the required adapter included, and is it intended for a stereo or compound microscope?
- Does the camera work with your operating system and available USB ports?
- Does bundled software provide live preview and recording, and can it save a format your editor opens reliably?
- What resolution and frame rate are supported in video mode, rather than only in still-photo mode?
- Will the field of view, parfocality, and exposure controls suit your specimen?
- What is the total cost after adapters, cables, and storage, and can you test the combination before the competition?
Examples of category differences
| Example | Connection and adapters | Documented video capability | What the page does not establish |
|---|---|---|---|
| Leica Flexacam C3 | C-mount system; Leica recommends different adapters for stereo versus compound microscopes. | Full HD MJPG recording at 30 fps. | Price, your microscope’s exact fit, and a universal operating-system requirement are not stated on the cited page. |
| OMAX 10MP USB 2.0 C-Mount Microscope Camera | USB 2.0 connection with a C-mount interface. | Live video streaming and bundled video-recording software are documented. | Price, every supported operating system, and compatibility with every microscope are not stated on the cited page. |
These manufacturer examples show the kinds of differences to compare, not a recommendation that either model is necessary. See the Flexacam C3 specifications and the OMAX USB camera page for the manufacturers’ current details, then verify the complete camera–adapter–microscope–computer chain yourself.
Troubleshoot common capture and editing failures
The video is black or heavily vignetted
Check whether the camera is seated in the correct port, whether the adapter is intended for that microscope type, and whether the capture software is using the correct camera. Recheck illumination and exposure before increasing gain. Record the fix and any changed setting in the capture log.

The image is sharp in the eyepiece but soft in the recording
Refocus through the camera view rather than the eyepiece, confirm parfocal adjustment, and disable automatic focus if it hunts during motion. Note whether the camera uses a different optical path or magnification from the eyepiece.
The exported file has dropped frames or no audio
Test a short recording at the intended resolution and frame rate. Close other applications, use a stable connection, and confirm that the editor’s project settings match the source. If the camera records no audio, narrate separately and identify the added track in the edit record rather than implying that sound was captured at the microscope.
Labels or scale bars disappear in the final export
Watch the export on the actual playback device. Missing fonts, unsupported transparency, or a crop applied at export can remove overlays that were visible in the editor. Burn in essential labels only after checking their spelling and units, then keep the pre-overlay source clip.
A judge asks for the original
Use the filename in your capture log to locate the untouched clip, not a draft export. If your fair does not require raw-file submission, you can still show the source and explain the edit history when transparency is relevant. Never substitute a re-encoded file and call it original.
Quick Recap
Final pre-submission checklist
- Current rules for the specific competition, year, and local fair have been checked.
- Every clip has a specimen identifier, capture date, microscope and camera description, connection, relevant optical and illumination details, software, and material settings recorded.
- Original clips are preserved separately from working edits and backed up.
- The edit record identifies trims, speed changes, annotations, image adjustments, compositing, narration, music, and export settings.
- Each visual receives an individual credit appropriate to its origin; internet-sourced visuals include their URLs.
- Signed releases for people shown are retained privately and can be produced if requested.
- The final export plays from start to finish, with readable labels, synchronized audio, and no draft material.
- The final filename, duration, export date, and software/version are logged, and a backup is available.
- The inspected presentation is treated as immutable when the applicable rules prohibit post-inspection changes.
- Any generative-AI use is acknowledged as required, and AI has not authored prohibited ISEF documents.
