Bitstream

  • Thumbnails Filmstrip with Frame Type and picture preview
  • Bars Filmstrip with Frame type and size
  • Frame reference dependency and hierarchy
  • Extracting NAL units and sub stream
  • Spec compliance verification
  • HRD and VBV buffer visualization
  • Displaying PSNR/SSIM metrics per frame on a timeline graph

Frame view

Prediction, transform and overlays

Frame

  • Dedicated view for each stage of frame processing
  • Extracting intermediate pictures to a file
  • DPB state for the frame
  • Graphically Analyze Coding Flow

  • Display PSNR/SSIM metrics as block based heat map

Statistics

Frame and Stream level stat, extract to file

Statistics

  • Quotation from spec for each syntax element
  • Whole bit stream & each separate frame statistics
  • Extract syntax and statistical data to a file

VQ Analyzer

Block view

Full pipeline of actions with coefficients, vectors and formulas

Block

  • Detailed information for selected block in Selection Info

  • View of bits in bitstream for Selected NAL/Frame/Block
  • Detect, classNameify, display and navigate to a bitstream error or level incompliance

Syntax Info

Values of specified bitstream elements instruct the decoder to take action

Statistics

  • Quotation from spec for each syntax element
  • Whole bit stream & each separate frame statistics
