Video Quality Caliper
available in Media Server Studio packages - Professional Edition and Video Pro Analyzer
Video Quality Caliper may have multiple applications in video developer’s hands.
- Single file view and playback
- Objective metrics graph visualization (only reference metrics for now)
- RD graph for group of coded files compressed from the same reference origin
- Side by side compare of 2 compressed stream as a single picture (ex. left side from one, right from another)
- Side by side compare of a compressed stream with original uncompressed as a single picture (ex. left side from one, right from another)
- Detection of unexpected visual artefacts
- Investigation of compression artefacts
VQC can be used a file viewer for a single stream. It supports
- Elementary streams and containers: MP2TS, MP4, MKV
- All popular compression standards - HEVC, VP8, VP9, MPEG2, AVC
- Uncompressed files, planar and interleaved
- 4:2:0/4:2:2/4:4:4 chroma formats and 8-16 bit depth
- Auto detection of compressed bitstreams
- Auto detection of uncompressed streams with option to customize your format if it is not properly recognized - to adjust resolution, color format, bit depth etc
- Playback with any zoom factor
- Works on Windows and Linux
Major function of the tool is to visualize objective Metrics
- PSNR for Y, U, V and Overall = (6Y+U+V)/8
- SSIM and SSIMb
- MWDVQM
- Allows to save data to a file and picture chart
- Visualize 2 metrics on a single graph - left handed axis and Secondary right handed metrics
GUI is essential component of productivity
- Open a file or group of files, independent or by user-defined template
- Flexible navigation in between frames, metrics graph preview of whole stream
- Average stream based metric for stream bitrate on RD-graph
- Clickable RD-graph with each point as a control of a graphic line
- Quick stream down sampled preview
- Mouse wheel and hot keys
- Amazing zoom to pixel values
- Customizable chart area
- Clickable chart area to select frame preview in a separate window
- Legend for a file mapping to a graph
- Splits for multiple streams preview
- Extended view of multiple streams
- Offset view for multiple streams
- Synchronous view for multiple streams
- Intel® Video Pro Analyzer interoperability to inspect selected frame
- Cached data size control
- Restart with previously working options
