Summary	0000166: Intra Frame issue
Description	Warning: Automatic cropping activated: Coded frame Size: 1920x1088 IntraProfile requires IDRPeriod >= 1. I am trying to encode at a high bitrates in intra frame mode, please see attatched config file. I think that it is set up okay.
Additional Information	The first on e I am not worried about as I know what it means, but the second one is confusing. Can you shed any light on it?
Tags	No tags attached.

Alexis Michael Tourapis 2009-03-02 17:40 developer ~0000297	Try to set IntraProfile to 0 and/or NumberBFrames to 0. You are combining this profile with inter type slices which does not make sense.

Fraz 2009-03-03 10:32 reporter ~0000298	Agreed, I have done this. Unfortunately when I run the encoder now it crashes the lencod.exe. I get as far as; Z:\OSTMW0050068-HDD\Media_Standards\Codecs\AVCI\JM\bin>lencod.exe Setting Default Parameters...
