.VIX File Extension
File TypeLightworks Video Index File
What is a VIX file?
File created by Lightworks, a video editing application; similar to the .MXF file; contains video and audio data that describes AVCHD media files with the .MTS extension used by Lightworks; referenced by Lightworks to streamline the editing workflow.
After a video is imported into Lightworks, the VIX file is created. It will be located in the Lightworks "Material" folder with the same name as the imported video but with the VIX extension appended on to the end. If the imported video is named V23P65J.mts, the new file would be V23P65J.mts.vix.
