Training videos without time reference are hard to evaluate. When exactly does the athlete lose time? In which section? Without a precise timestamp in the video, the analysis remains guesswork. IRIS solves this: The adapter encodes a highly precise timestamp directly onto your camera's audio track — frame by frame. The Lympik Web-App automatically reads this timestamp, cuts the videos, assigns them to the correct athlete, and synchronizes everything with timing and GPS data.
No manual cutting. No searching for file names and tedious manual assignment. No post-processing.

IRIS can be mounted on any common DSLR or film camera — either via the 1/4-inch threaded screw on the tripod mount or with a cold-shoe adapter. No tools, no modifications.
Step 1 — Mount: Attach or screw IRIS onto the camera. Connect the audio cable to the camera's microphone input.
Step 2 — Wait for GPS fix: Turn on IRIS. The LED flashes blue until the GPS signal is found. Once it lights up green, the device is ready.
Step 3 — Record: Operate the camera as usual. IRIS runs in the background and encodes each frame with a precise timestamp.

IRIS encodes a highly precise timestamp directly onto the left audio channel of your camera. The normal microphone can be heard on the right channel. After training: Upload videos from the SD card to the Lympik Web-App. The app decodes the timestamp from the audio track, automatically cuts the videos, and assigns each run to the correct athlete. The timecode is filtered out of the video, only the microphone can be heard.
