QC Timeline
QC Timeline feature
QC Timeline V2 (available since 1.11.25) replaces the earlier timeline with improved rendering and clarity. V2 keeps the same track-based workflow but is faster to render and clearer at high density.
OmniScope features a very useful QC tool called QC Timeline. It can be toggled in the QC top menu and allows you to see all the QC events as well as audio waveform, HDR stats, thumbnails and many more.
The timeline is built in realtime based on incoming frames and uses timecode to reference events. This means you can monitor your SDI signal as it comes in and will follow your playhead in real-time while you move around your timeline.
The timeline can display tracks for HDR statistics, gamut percentage, black-frame percentage, audio loudness, audio waveforms, blanking, luminance, thumbnails, and PSE events. Video Events groups HDR gamut, black-frame, and dead-pixel detections into labeled lanes (depending on your license). Silence periods are shaded directly on the Audio waveform track.
Each track can be toggled on and off in the right click context menu:
You can also change the size of each track by dragging & dropping the top/bottom edges of the tracks. You can also re-arrange the tracks by dragging & dropping the track headers on the left side.
Scrolling and Zooming
Starting with version 1.11.55, use the mouse wheel over the timeline plot to navigate:
Mouse wheel
Scroll vertically through tracks
Shift + mouse wheel
Scroll horizontally through time
Option (macOS) / Alt (Windows) + mouse wheel
Zoom in or out around the mouse pointer
Move the pointer to the time you want to inspect before zooming. Scrolling stops at the timeline's bounds.
On macOS, two-finger trackpad scrolling pans the timeline horizontally and vertically, and pinching zooms around the gesture position.
The timeline toolbar also provides buttons to zoom out and show the full timeline, or reset to the default zoom centered on the playhead.
Using Free Run for Quick QC Scans
When working with video files, enable Free run mode with the rabbit button in the timeline toolbar or from the source's Settings tab. This processes frames as fast as possible, without waiting for real-time playback. The QC Timeline will be built at accelerated speed, allowing you to scan an entire file in a fraction of the normal playback time. See Video File — Free Run Mode for setup details.
The context menu allows you to reset the timeline (start building it from scratch), clear the bookmarks (you can add them through Stream Deck action or cmd/ctr+B key shortcut), import and export the timeline to file (for further quick access) as well as exporting the QC events as markers via EDL.
In OmniScope 1.11.54 and later, the context menu also includes Send to Secondary Window. Each input's timeline can be placed independently, and its assigned window is saved in layouts.
Also in 1.11.54 and later, thumbnail history remains visible when file playback loops or the playhead moves backward. Resetting the timeline starts a clean thumbnail history. Luminance-track Min/Max tooltips identify their values as code values, not nits; tracks that measure actual HDR luminance continue to use nits.
