How do I use an image sequence?

This article explains how to import, load and play an image sequence or video stream in REFLEKT ONE Sync.

GENERAL INFO: 

 

In the Test & Adapt mode you can use an image sequence or video stream you have recorded via the Analyze & Record features or an already existing one in order to test its accuracy in relation to the model and its settings.  

NOTE: If you want to use a video which was not recorded in REFLEKT ONE Sync, you have to convert it into image sequences first. For more information read the article here.

To use an image sequence, you have two options:

  • You can add a source (image sequence) from your computer and then select this source for import.
