TestGen AV Sync turns an iPhone or iPad into a portable video and audio test-signal source, built on the same pattern generation engine Drastic ships in its Broadcast products. Point a camera at it, feed it into a capture card, hold it in frame for on set, or use it to line up a monitor. The signal is generated on the device in real time - no files, no streaming, no network.
TestGen AV Sync provides a free version with most of the important patterns, as well as a Pro version to add specific advanced patterns and features.
WHAT IT DOES

TestGen AV Sync for your iPhone

TestGen AV Sync for your Apple TV
Send professional standards based test patterns through your signal path. Monitor and diagnose common faults, and calibrate devices including cameras and lighting panels. Make sure with TestGen AV Sync.
- 270 broadcast test patterns, including SMPTE and EBU color bars, PLUGE, luma and chroma ramps, multiburst, zone plates, convergence circles, grids, pixel-resolution charts, gamma strips, HDR clipping and filter charts, and much more.
- Sample-accurate A/V sync markers - a phase-coded audio pulse aligned to the video frame, so you can measure lip-sync error end to end through any signal chain.
- Frame accurate time code burn-in - HH:MM:SS:FF with drop-frame support, date stamp, or UTC.
- QR frame data - every frame can carry its frame index, UTC timestamp, frame rate, pattern ID and audio phase as a machine-readable QR code, so an automated test rig can read the delay straight off a recording.
- Flash cues - full screen or edge flashes at a chosen interval for latency and shutter testing.
- Multi-pattern output - show up to five patterns at once in a split screen layout.
- Frame rates from 24 to 60 fps, including 29.97 and 59.94 with correct drop-frame time code.
- HDR output in HLG and PQ, plus Display P3 and Rec.2020 wide-gamut color on supported devices, with an optional 16-bit float rendering path for band-free gradients.
- Presets - save a complete configuration and export it or import it as JSON to share a setup with the rest of the crew.
WHO IT IS FOR
TestGen AV Sync is designed for Camera operators, DITs, broadcast and post engineers, AV installers, live-event and streaming technicians, QC departments, and anyone who needs a known-good reference signal without carrying a rackmount generator.
FREE AND PRO
The FREE version generates SMPTE BT.709 75% and 100% color bars, SMPTE RP-219 bars, SMPTE 303M, a 7-step luma staircase, a grid-and-dots chart, a Rec.709 white window, a zone plate, plus full white and full black at up to 30 fps in Rec.709, with all three A/V sync audio signals and full preset support - enough to check a signal path or line up a monitor.
The PRO version is a single one-time in-app purchase - not a subscription - that unlocks the remaining 259 test patterns, multi-pattern layouts, time code/QR/flash overlays, 50/59.94/60 fps, HDR (HLG and PQ), and wide gamut output.
