## What is TC Latency Tester?

TC Latency Tester helps you check video and wireless transmission delay frame by frame. Record the source and delayed display together, pause the recording, and compare their timecodes.

Choose 23.976, 24, 25, 29.97, 29.97 drop-frame, 30, 50, 59.94, or 60 fps. Set a start timecode, show the current time, count up or down, and save presets. Full-screen display, frame emphasis, an identification pattern, a sync marker, and a short beep are available on iPhone and iPad.

Timecode is derived from elapsed time, so missed display updates do not accumulate as lost frames. Physical display, audio, and camera delay still apply. The app does not synchronize external devices.
