What's New in VideoCharge 3.3

New product version includes several altered algorithms as well as a number of new functionalities.
  • 1. Split option is advanced.
    • a) Automatic Split by Scene is added.
      This mode has a parameter that may take on two different values: Motion and Curtain. When splitting video with Motion parameter, the motion movement vector is being analyzed for every frame, and switch to creation of the next clip occurs on scene change. When using Curtain parameter, creation of the next clip begins with the advent of curtain (completely black frame) only. That enables to split video file which contains several independent video clips simply, avoiding motion analysis.
    • b) Possibility to split video into specified number of parts is added. Simple algorithm can split for example a hour-long film into two parts of 30 minutes apiece.
    • ) Split by Size algorithm is renovated.
  • 2. Resize algorithms are renovated; new algorithms are added: Lanczos3 (3-point), Hann (4-point), Lanczos8 (8 - point).
    Resize options set is expanded:
    • a) Quality parameter is added. It establishes quality or speed priority.
    • b) Delta Ratio option for "Preserve aspect ratio, no letterbox" Resize type is added. It's intended for slight stretching of an image, which deflates dimensions of the LetterBox. This option is eminently useful for resizing 16x9 into 4x3 without sizeable truncation of an image.
    • c)Besides, now it is possible to assign one of the available values (16/9, 4/3 or Source ratio) to the Aspect Ratio variable.
  • 3. Possibilities for creation of WMV files are enlarged. Now Variable Bitrate (VBR) is available, namely:
    • Quality VBR
    • Unconstrained VBR
    • Constrained VBR.
    That allows to create more qualitative video.
  • 4. Possibility to use images with transparent background for creation of watermarks is added. The new value type for specifying Watermark Area - Fixed - is also added. "Fixed" type enables to specify Area precisely for different-type input files (differing by frame size). Value of Fixed type point is being computing relative to its paired point (e.g. Left - relative to Right, Bottom - relative to Top).
