BitrateViewer Icon  BitrateViewer for Mac - Preferences


Some settings of BitrateViewer for Mac cannot be changed dynamically by using the menus or keyboard shortcuts. For these settings to change you open the preferences panel via the application menu. Changes that you apply on the preferences panel will be saved into the shared user defaults controller - thus, these changes will be propagated to all open windows of BitrateViewer for Mac. Please note, that the initial release of this program can open only one window at a time. The preferences panel is organized in three pages:

Scaling Preferences

Scaling Preferences

If you want to use a fixed scale for the histograph output instead of an auto-scaled view, you can choose the preset value for the fixed maximum value on top of the histograph view:

  • Fixed scaling limit
    This is an output field; it shows the current active value of the shared system preferences.

  • Set fixed scaling limit
    First select the displayed bitrate unit for the scale in kbps or Mbps for standard or high definition assets. Then choose an appropriate range within the decade with the segmented control. At last you can select a predefined ranged value with the stepper right to the number text field. Click the »Apply« button on the right of the bitrate unit group, when your selections match your needs.
Drag & Draw Preferences

Drag / Draw Preferences

As application default, drag and drop of video files into the histograph view is activated. You can change that here:

  • Allow drag'n drop files
    Click this option away to disable, that you can drag any files onto the histograph view.

  • Dropped file opens new window
    As of release 2.0 of BitrateViewer for Mac the application is a multi-window application. So, if this option is activated, you can display multiple files concurrently, each one having its own window.

You can configure two different scaled types for the top ruler top ruler to be displayed:

  • Assistance ruler type
    Choose between a four quarter or a ten tenths divided scale to draw the top ruler.

MPEG Reader Preferences

MPEG Reader Preferences

For MPEG-1 and MPEG-2, a full video frame reader will be activated for input files upto a size of 128 MiB (+10% tolerance) as the default setting. The full read of those files is assumed to be quick enough to get not registered by the user for that time needed for the tool to estimate the frame count of an input file after it has been opened. If you feel that this primary read takes to much time on your system or if your input source is a CD, DVD or BD, then you can either deactivate using the full video frame reader or change the threshold of the buffer size in percent upto the tool will choose full reading of a file.

  • Use full video frame reader
    Uncheck this option to deactivate the full video frame reader. If this option is left checked, you can use the stepper and the slider below to select a percent value based on the fact, that 128 MiB mean 100%. Your selected percent value is displayed in the text field left to the stepper and a calculated value in MiB with this new percentage reflects the effective memory used for the full video frame reader. The slider is used for rough changes to the value, the stepper is more accurate as its value increments by 1. Click the »Apply« button to accept your changes.

Notes: The full video frame reader is always inactive when working on VOB files! The internal threshold is automatically increased by 40%, if the input file is a transport stream. That's because TS has some more overhead in its MPEG headers. Generally you will see, that the performance in analysis of transport streams is remarkable worse than on elementary or program streams. The reason is, that two stacked demuxers will be used to get the video data of a stream and that gives a lot of packet overhead.

System Preferences

  • Reset to standard settings
    This option does not depend on the current preference's page selection - it is always visible. Click the »Apply« button to set the application default values for all preference's pages and also to all application dynamic options.
