Thanks for releasing FirstLight, still trying to figure how to fit it on my workflow.

Anyways, when I change the settings(White balance/color matrix/gamma) and I play the footage, it flickers between the original settings and the modified settings.

Any solutions?

It sounds like your file has two different GUIDs in it. How was the CineForm mov created?

Hmm, it was created by ReMaster...
How do I remove the other GUIDs?

Which version of ReMaster? What was the source to ReMaster?
