Intelligent Automated Correction

Patented Video Correction

• Corrects Luma/Chroma levels if outside limits
• Corrects black level if outside limits
• Corrects RGB gamut if outside limits
• Corrects Analog video dropouts
• Insertion / removal / change of length of color bars
• Insertion / removal / change of length of black sequences
• Correction of start timecode
• PSE flashing correction (Ofcom / ITU)
• Dead Pixel correction

Audio Correction

• Peak levels: peak level correction if TP dB limits exceeded
• Loudness: loudness correction if given LKFS/LUFS exceeded
• Audio levels: correction if PPM level limits exceeded and peak attenuation
• Audio bit depth correction

Tests Available

Container Checks

MXF structure, DPP metadata, compare wrapper/ essence, number video/audio streams, PIDs, file, bitrate, SPS/PPS, video/audio duration, timecode start/continuity, clean aperture, AFD, MOV Atom (iTunes), IMF validation of metadata & essence, Enhanced Syntax Check

Video Checks

Video codec/profile, encoding syntax, MBAFF, video bitrate VBR/CBR, frame size, frame rate, video buffer size, frame aspect ratio, pixel aspect ratio, GOP length, GOP structure, field order flagged/baseband, cadence, drop frame, chroma format, luminance, black level, chroma level, HDR MaxFALL/MaxCLL.

Note: Vidchecker 8.2 supports the validation of Dolby Vision metadata, allowing you to ensure your HDR content is ready for consumption. SDR in HDR test will let you know how much of your content is using the full HDR dynamic range.

Other checks include RGB gamut, quality/blockiness, analog drops, digital drops, video stripes, corrupt frames, letterboxing/pillarboxing, black frames/sequence, color bars, freeze frames, layout checks, PSE flashing/ harmful patterns (Ofcom / ITU), video segment reporting, Dead Pixels, and Media Offline.

Audio Checks

Each track: audio codec, bit depth, sample rate, audio bitrate, number of channels, channel layout, channel mapping, tones, phase coherence between channels, track present during video, min levels, peak levels, clipping, clicks and pops, PPM, DialNorm, integrated/short term/momentary loudness (ITU/EBU/ATSC/ CALM/BS-1770), BLITS, GLITS & EBU test tone checks, digital silence. Supports 32-channel audio
