Any reason why

When I export using adobe to picvideo that it causes it to interlace, but Vdub does not? I've even used just Adobe Media Encoder from a raw d90 file and it still does it...I'm stumped.
 
normalized is what you need when working with d90 footage, otherwise you can get the luma cliping problem you had before. there's a setting for interlaced too though, just set it accordingly. however, interlaced encoding doesn't really interlace the footage, that's typically a host app issue.

Matt, while we are on the topic, what settings in the configure window of PicVideo should be checked or unchecked? I want to make sure I have the codec set up for the best possible use with the footage.
 
The interlace is just a hit or miss with this codec and I have no idea why. I re-checked the "encode normalize yuv" and it still interlaced. but however, it didn't affect my luma or chroma when unchecked like you said it would, it only affected it when the "assume normalized yuv" is unchecked did it mess with it. the interlace problem I have no idea. not sure if it's the the host app cause I ran a raw d90 avi through adobe media encoder without premiere and it interlaced, but I did it again and it was fine...so it's just whatever. I just keep doing it until I have it work right.

my settings are for decompressor
check/enable codec
check/advance deblocking
check/assume normalized yuv
uncheck/swap fields
uncheck/force yuv output

compressor
quality 20
luminance 0
chroma 0
check/encode normalized yuv
check/ subsampling 4:2:2
uncheck/2 fields if more than
 
it affects the luma, that's the definition of normalized yuv. i said it *could* though, because depending on your settings you may never see it. what i meant about the host app is that it typically doesn't matter if you encode progressive material as progressive or interlaced, it should look *exactly* the same since both fields are from the same frame and captured at the same time (actually interlaced footage encoded as progressive will still be interlaced as well). if you get interlace lines it's most likely something your host app has done, maybe you've retimed the footage, or scaled it? check your project settings to see if it's set to render interlaced. your settings are definitely correct for progressive material.

check out that part again, where the only host app used was media encoder. there are no host settings other than the codec.
 
Well, you gotta explain what you mean by interlace then because progressive material is encoded as interlaced all the time and it doesn't become interlaced. It's called psf and it's used for progressive material on well known formats like digibeta and hdcam, even 1080p hdv and 25/30p dv. Interlace is a property of the image itself and no codec will ever change that. The difference is purely technical.
