Difference b/w Elecard StreamEye Studio and Elecard StreamEye Studio Pro.
Date updated: January 23 2014
What's the difference between Elecard StreamEye Studio and Elecard StreamEye Studio Pro?

Our FAQ about differences between the Studio and the Studio Pro versions refers mostly to the difference between Elecard StreamEye & Elecard StreamEye Pro which are parts of the corresponding Studio set. Major differences between StreamEye (tool#1) and StreamEye Pro (tool#2) applications:

  1. Tool #1 will always implement functionally which it currently offers; updates for tool #1 will be merely bug fixes. Tool #2 will evolve to comprise both updates & upgrades, i.e. besides bug fixing tool #2 implements new features and modules.
  2. Tool #1 does not perform video data metric calculations. Tool#2 allows calculating EPSNR via estimating video quality without a source stream.
  3. In contrast to tool#1, tool #2 integrates the following modules:
    • Buffer Analyzer which allows visualizing a VBV chart for a current stream i.e. allows revealing overflow and underflow errors of the encoder’s buffer.
    • Raw data module which allows uploading source/raw data for comparing with the encoded stream and calculating PSNR metrics.
    • Coefficients Info which shows different macroblock coefficients.
    • Histogram window shows YUV component histograms for the selected frame.
    • Hex Viewer window shows the opened file content in binary, hexadecimal and ASCII modes.
    • Zoom window shows video frame on a large scale (32:1). The window allows visualization of a macroblock grid and YUV pixel value.
    All these modules are synchronized with each other to show full diagnostic information for selected frame, macroblock, etc. For example, if you navigate on a specific frame you will be referred to a corresponding coordinate in the VBV chart in the Buffer Analyzer window and so on.
  4. Tool #2 offers feature of thumbnail preview which means that on the main window where you can navigate between columns specifying the sequence of I, P, B frames, under each column the corresponding picture (in small size) is displayed
  5. Both tool #1 & tool #2 support scalable video coding (SVC) which is the extension of H.264/AVC. However in to basic SVC support tool#2 also allows displaying levels corresponding resolution/bitrates as well as switching between represented levels.
