Manual Camera vs TestGenAVSync

With mcamera you can control parameters that are not available in the standard camera app: - Focus distance - ISO sensitivity - Shutter speed - White balance With manual control of shutter speed you can keep ISO as low as possible which will give you less noise on the photos. Long shutter speed would also give you opportunity to take photos with smeared elements such as car lights or smooth river water. Terms of service: https://vdugnist.com/mcamera_tos.html

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 Technologies ships in its broadcast products. Point a camera at it, feed it into a capture card, hold it in frame 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. WHAT IT DOES • 270 broadcast test patterns — SMPTE and EBU colour 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 timecode 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 two to five different 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 timecode. • HDR output in HLG and PQ, plus Display P3 and Rec.2020 wide-gamut colour on supported devices, with an optional true 16-bit float rendering path for band-free gradients. • Presets — save a complete configuration, and export or import it as JSON to share a setup with the rest of the crew. WHO IT IS 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 rack-mount generator. FREE AND PRO The free version generates SMPTE BT.709 75% and 100% colour bars, ARIB STD-B28 HD 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. TestGen Pro is a single one-time In-App Purchase — not a subscription — that unlocks the remaining 259 test patterns, multi-pattern layouts, the timecode, QR and flash-cue overlays, 50/59.94/60 fps, HDR (HLG and PQ) and wide-gamut output.
