QCView

QCView player window

QCView is a media player and reviewer for Windows and macOS, built for artists and post-production teams who need accurate, color-managed playback of video, EXR, and image sequences.

Key Features

Playback

  • Hardware-accelerated video decoding — Vulkan/D3D11-video on Windows, VideoToolbox on macOS, with FFmpeg software fallback
  • HDR10 (PQ / ST.2084) on Windows via DXGI + DirectComposition; Extended Dynamic Range (EDR) on macOS
  • Frame-accurate stepping with press-and-hold fast forward / rewind
  • Playlists with cross-clip seek, per-clip in/out trims, and hover thumbnail filmstrip
  • Embedded timecode (DV / TimeCode / MXF) with selectable origin
  • Audio playback (WASAPI / CoreAudio) with per-channel routing for multi-stream broadcast deliveries
  • A/V sync offset trim, separate dual-view value

Image Sequences

  • OpenEXR with multichannel and multipart support
  • TIFF, PNG, JPEG sequence playback

Color

  • Live OCIO color management, with a colour chain per clip and per side of a dual view
  • Bundled OCIO configs: ACES 2.0, ACES 1.3, Blender 5.2, Blender 5.1
  • A second, OCIO-free colour engine, minColor: Input → Highlight Knee → AgX → Rendering (un-tone-mapped or OpenDRT) → Display, from the minColorAE core
  • Compact Mode (Ctrl + Shift + C): the window becomes the picture plus one slim strip, no title bar, no panels
  • Always on Top (Ctrl + Alt + T): a pin on the transport row and the Compact strip keeps the window above every other app’s, and is remembered
  • Highlight Knee for reviewing HDR masters on SDR displays; ASC CDL and .cube LUTs
  • GPU vectorscope and waveform (nits on HDR sources, manual % / nits scale) with a peak readout, and a per-clip Transfer override for sources without usable tags
  • Screenshots and notes exports apply the OCIO transform

Live Feeds and Output

  • Live sources: After Effects and Premiere Pro through QCBridgeAE (full-float picture, Premiere’s audio), Blender through QCBridge, and SRT streams
  • Notes on a live feed: freeze the frame, draw, review it again later; notes live in the project with capture time and host timecode, and open in minNotes
  • Output: the corrected viewport with mixed audio as an NDI® source (QCBridgeN), out of an AJA device’s SDI and HDMI as 10-bit RGB at 1080p or UHD, SDR, PQ or HLG (QCBridgeA), or as an H.264 + AAC stream over SRT or RTMP to Louper or any server, encoded by the GPU, with automatic reconnect

Review Tools

  • Annotations + notes with brush, line smoothing, screenshot illustrations, and Markdown / HTML / PDF / DOCX export
  • Dual-view comparison: side-by-side, split-wipe with mouse-drag seam, difference mode, independent A / B controls, a live feed on either side
  • Title-safety guides for broadcast and social-media deliverables
  • Live background switching for alpha-channel review

Project Support

  • Adobe project metadata import (Premiere / After Effects timecode + project links via ExifTool)
  • Custom project files (.qcvproj)
  • qcview:// URI scheme for sharing file paths
