Organize Video References Around the Moment You Need
A useful video reference needs more context than a filename. Record what happens, where the useful moment begins, and what you want to study. Keep the original clip available so a still image does not become your only record of the movement.
Index the clips and test playback
Add the content folder to a refern workspace and let indexing finish. Open a representative clip to check playback before organizing a large collection. A container extension alone does not guarantee that every codec combination plays on every system.
Use type:video to find video entries. Add tags such as reach, turn, or camera-pan when they describe how you plan to retrieve the clip. Keep title, creator, source, and context in metadata rather than trying to encode everything in a filename.
Study a specific interval
Use the video player's frame stepping and A-B section controls to inspect a motion. Place markers where they help you return to a pose or transition; give each marker a label that explains its purpose.
For example, mark "weight shifts before foot lift" rather than simply "good frame." The point of the marker is the observation, not the number of markers you create.
Save a still or a section when needed
The player offers frame saves/copies and section export actions. You can save a frame straight into any workspace folder. A saved PNG frame is useful for comparing silhouettes on a canvas. It cannot preserve timing, so keep it connected to its source context.
Choose the export option that fits the handoff and inspect the output. A re-encoded clip and a stream-copy export have different boundaries; stream-copy cuts can be constrained by keyframes. An animated WebP loop is limited to a short section, currently up to 30 seconds.
Marker/section timeline exports are available as OTIO or EDL. Test an export in the recipient's editor rather than promising that every timeline application will import every field identically.
Keep the project board readable
Use a few key frames for side-by-side comparison and return to the clip to study the transitions between them. Put the action question beside the board, such as "does the torso lead the turn?"
Back up both the media and workspace data that contains your organizing work. For a shot-focused example, see the storyboard workflow; for drawing from selected stills, see Timed Study.
