Hi Tony,
Actually I took 2 minutes AVI with RAW8. Didn't know need to de-Bayered.. all came out with B&W after RegiStax. Realised after few readings to de-Bayer. I used FireCapture's deBayer.exe with HQ Linear mode before RegiStax. Then BW turned out in colur! Still not sure how to use RegiStax properly! Probably I need to polish images more on RegiStax. Not sure I go down to photo processing program at this stage.
