Hi Ra-ey,
Perhaps it would be best to move this into our support queue – we have technicians that are available to assist you in diagnosing this problem. Please send an email to support@borisfx.com detailing the problem and someone will get in touch and hopefully assist you in resolving the issue.
Please make sure to include in your email to support all of your system information. What I mean by this is the processor type/speed, amount of RAM, OS type and version, version of Avid, version of AvidFX, and whether the problem is isolated to when you are working in the Avid timeline or if it happens when you use AvidFX in standalone mode also. Also include the details of the project that you are working with, frame rate, frame dimensions, field order, PAR etc.
Thanks,
Peter.
