Purpose

 

To declare the pixel aspect ratio standard used by incoming files, adding the new pixel aspect ratio metadata.  

 

Many camera raw formats include the pixel aspect ratio metadata, so nothing need to be done for those formats (you can see their metadata by dropping a media file in the nodegraph panel and taking a look to the node metadata properties).

 

But in other cases the pixel aspect ratio metadata is not present, so Mistika will have to use the default (square pixels).  If you know that the pixels of your images have non square pixels and you plan to do aspect ratio conversions later then you will need to declare the pixel aspect ratio explicitly by using this node (before passing the media file to encoder nodes applying aspect ratio conversions).

 

Inputs

 

Input: Any media files

 

Outputs

 

Output: The input files with the new pixel aspect ratio metadata.

Node specific properties

 

Pixel Aspect Ratio: A combo box offering the supported video standards.

 

Overwrite: If deactivated, the new pixel aspect ratio metadata value will only be applied to media files lacking pixel aspect ratio metadata information, but if they already have it will not be overwritten. This is convenient to provide a default for new media appearing Watcher folders,  without knowing what kind of media files will appear in there in advance.
