Raw & encoded video inspection for macOS
⌘F reopens the current file under different parameters while keeping frame position and zoom.⌘6) repairs tags without re-encoding. Rewrites the color tags, the SMPTE ST 2086 mastering display volume, and the MaxCLL / MaxFALL content light level of an MP4 / MOV in the container boxes, the coded stream's own signalling, or both, so the two layers agree afterwards. Fixes stage into a reviewable plan with staged values shown inline against the file's current ones, and write to a new file that must pass verification before the save succeeds: video and audio byte-identical to the source, tags reading back exactly, the file re-opening. The catalog covers chroma siting, aspect ratio, HLG compatibility, stripping dynamic HDR metadata, QuickTime compatibility for in-band files, fast start, edit-list repair, and per-field expert edits down to the parameter sets. The file you opened is never modified.⌘1) for measurable repair. A non-destructive operation stack: legalize levels in codes, nits, or RGB, swap or neutralize planes, bake a range conversion, patch pixels with exact values, interpolate over dead pixels and dropped lines, crop, pad, rotate, flip, cut, trim, and subclip. Every scope reads the frame through the stack, each operation reports what it actually changed, and a measurement can become the selection the next operation acts on. Work in the file's own layout or in RGB 4:4:4, scale to a target resolution on export, compare the edit against the source with real metrics before it ships, and replay the whole recipe from the command line. The export verifies every frame byte for byte.⌘2) with cross-validated metrics. Load a reference and a distorted version, even in different pixel formats or transfers, and view them side-by-side, flipped on a key, wiped with a draggable divider, or as a difference image with channel, heatmap, and binary styles. A temporal offset lines up clips that do not start on the same frame. Per-frame PSNR, SSIM, MS-SSIM, VMAF, CAMBI, ΔE2000, and ΔE ITP come with a chart, sequence aggregates, and a jump-to-worst-frame button. The run is progressive: the frame on screen measures first, numbers land frame by frame, and cancelling keeps everything measured so far.⌘3) reads the part of the frame you point at: region statistics with jump-to-min/max, line profiles in codes or nits, a pixel ruler, a region histogram, and Scan Region to watch one window across every frame. Conform (⌘4) turns a delivery spec into a checklist, one row per requirement, each failing row carrying the fix that resolves it on the surface that performs it, and rows it cannot measure are marked skipped rather than passed; HDR10, Rec.709, and mezzanine presets ship, and your own specs sit beside them. Scenes (⌘5) groups the clip into shots with per-shot light levels, complexity, legal levels, and flash-risk indication, checks cuts against keyframes and against HDR10+ metadata boundaries, and exports the shot list as a keyframe plan, chapters, markers, an EDL, or OpenTimelineIO.⌘G) writes its own test material. Twenty-five patterns: color bars, HDR bars, PLUGE, range checkers, ramps and bit-depth ramps, gamut sweeps, zone plates, gratings, checkerboards, a chroma-siting probe, graticules, PQ stairs, luminance windows, HDR grey ramps, a 24-patch ColorChecker-style chart, and a temporal set covering motion, cadence, drop detection, flash sequences and noise. Overlays add a frame counter with a machine-readable strip, labels, a border with lettered corners, and a centre cross; several segments in one clip make a scene-cut test that Scenes mode reads back. Every value is computed for the exact format, matrix, range, bit depth and chroma siting picked, through the same color and transfer math the scopes measure with, and chroma is rendered at each plane's own sample position, so a 4:2:0 file carries chroma where its siting says it is. Output is raw or y4m, every written frame is read back off disk and byte-compared before the write reports success, and the same specification always produces the same bytes. Fourteen presets cover the usual starting points, and videre generate runs the same engine with the same preset names.videre command-line tool with ten subcommands (generate, inspect, compare, bitstream, container, retag, edit, verify, conform, scenes) built on the same code as the app, so scripted QC gets identical numbers. verify and conform exit nonzero on a failure, so a pipeline can block an upload, and JSON reports carry a stable, versioned schema. Three Shortcuts actions and Finder Services cover inspect and compare from the desktop. The tool installs from a menu item in the app.ffmpeg's psnr filter to the printed precision on average, min, and max. VMAF and CAMBI are gated against Netflix's reference vmaf CLI built from the same release. HDR10+ parsing is checked against hdr10plus_tool fixtures, and the renderer carries golden-image tests against a CPU reference.
