Video Inspector

Video Inspector with monitors ganged

The V6 Video Inspector is a simple but unique application designed to provide an easy way to directly compare 2 video clips on a pixel-by-pixel basis or monitor with Video Scopes – engineered for colorists

Open the Video Inspector from the V6-Q main interface – right-click and select “Video Inspector”

Once open, right-click or use the File menu to load a source clip into the Master Clip panel for inspection – you can use the Video Inspector to view pixel color values or open the Dual Scopes for monitoring Luma Overlay, RGB Parade, Vectorscope or Histogram data

Dual Scopes Monitoring Video 1

Use the transport controls to play / pause playback or frame step forward and backward. The scopes will automatically update during playback dependent upon system resources

The Video Inspector also includes a CIE Color Panel for displaying the current frame color data within standard gamut and color system charts

You can easily select between color systems with the button and drop-down menu at the bottom of the interface


For direct video to video comparisons, right-click to load a video conversion from the Master Clip into the Video 2 panel to compare videos side-by-side – or you can import any second clip to monitor with the color info tool and the video scopes

Use the gang button to manipulate both video clips simultaneously using the transport buttons to play Рor use the scrollbar under the left-hand viewer to scrub both videos to a frame you wish to examine. Scrubbing is live and videos are re-synced automatically when playback stops or when the playback trackbar is released

Players not ganged

Click the gang button again to enable the Video 2 trackbar and decouple the video players. Scrub either video at will or play them simultaneously from any point in either video – the Dual Scopes can monitor both video clips separately, or can be set to monitor either Video 1 or Video 2 – this way you can monitor a single clip with both scopes set to different parameters (i.e. monitor Video 1 with Luma overlay and RGB Parade). You can switch the scopes to monitor either or both videos at will making for a very powerful evaluation tool!

Mouse over the left-hand panel to evaluate the pixel under the cursor in both clips – RGB and X/Y coordinate values are displayed underneath each clip panel. Double-click to lock-in (or unlock) current pixel values for closer examination or comparison between frames

Use the zoom button to expand the frame to 100% size within the player window, then click and drag the mouse inside the Video 1 window to re-position the frame in both players – allowing for precise pixel evaluation

Videos will play or scrub with any combination of conditions set

Generate Metrics

You can also run metrics reports to provide automated computer analysis and quality tests. Select between SSIM or PSNR metrics

Compare Oranges to Oranges…

In order to keep your conversion analyses honest, it is best to setup the conversion (to be tested) – to convert with other-than aac audio. AAC audio formats actually embed a time offset in the video clip in order to maintain audio / video sync throughout the converted video. This may cause a delay in the first frame – which will in turn offset the analysis and consequently show false positives

You may notice a slight difference in the duration shown for source clip opposed to comparison clip. This is also an audio artifact – it is common for and audio track not to match 100% with the last video frame – causing a slight discrepancy in duration. This time should be within merely hundredths of a second – larger discrepancies may indicate other transcoding problems (extra frames, wrong framerate, etc.

When converting with the Media Command Builder you can elect to render H.264 to an MOV container – you can then select Alac or PCM audio from the drop-down audio format selector to ensure your clip lengths match
