The problem
Operant data and video tracking live in separate systems
Operant conditioning chambers produce timestamped event logs (lever presses, rewards) while video tracking produces spatial data. Combining them requires manual temporal alignment after the fact — error-prone and time-consuming.
- Operant chamber software and video tracking software run on separate clocks
- Post-hoc alignment requires identifying synchronization markers in both data streams
- Misalignment of even 100 ms can shift behavioral events to wrong operant epochs
The solution
Hardware-synchronized event capture on the video timeline
ConductVision receives TTL pulses or serial events from operant chambers and logs them directly on the video tracking timeline. Events appear as synchronized markers — no post-hoc alignment needed.
- TTL and serial port event capture synchronized to the video frame clock
- Operant events displayed as real-time overlay markers on the video during acquisition
- Unified export: tracking coordinates and operant events in a single time-aligned output
