Problem encoding captured video

[bigdog660]

Hello,

I've captured video from a laserdisc at 720x480@29.97, and this is screenshot of the video in avi format.

I then use this script to crop the video, and to perform an Inverse Telecine (IVTC):

AVISource("H:\test.avi")
AutoCrop(0)
Telecide(order=0)
Decimate(cycle=5)

The problem is, when I try to encode the video in CCE, I get this result:

I have set the aspect ratio in CCE to SAR 1:1, and have tried 16:9 and 4:3, but with no luck.

What am I doing wrong?

A second question: Since I'm doing IVTC in AviSynth, there is no need to do 3:2 pulldown in CCE, correct?

Also, since I've done a ITVC on the video, it means the video is now deinterlaced, and I can encode the video in CCE as progressive, correct?

Lastly, when I try to use Trim(begin, end) in the script above, I get an error in my script. Any idea why?

Sorry about all the questions, I pretty new to this stuff. I'm trying my best to follow the guides.

Thanks,
bigdog

I think CCE doesn't like non-standard resolutions. You should either forget about cropping or crop and add borders later in the script to get to 704x480 or 720x480. And yes, after IVTC you can encode as progressive.

Okay, I notice after IVTC my fps is 23.97. Is the slower fps going to cause my audio to loose sync?

Nope.

When I took my AVI, and cropped it in VirtualDub, then fed it in to CCE, it worked. The problem with doing this is I have to use full processing mode, and I loose some video quality when I reencode.

Even though I encode (and then reencoded) using PicVideo MJEPG @ compression 20, I notice a slight degrade in the video. So this isn't going to be a viable option for me.

Sure wish there was a way to make CCE work with cropping through AviSynth.

I am also attempting to use VagueDenoiser(threshold=4, method=1, nsteps=6, chroma=true) in my script, but have a problem with is saying resolution unsupported.

Hummm, seems like I'm not having much luck here. :(

I think AutoCrop is causing the problem for you, possibly cropping in a bad way.

Try setting the Crop parameters manually instead of AutoCrop, like Crop(left,top,-right,-bottom). You could also try opening your script in VDub and see what it says.

Ok, Boulder... thanks for your help. I'm gonna give it a rest for tonight, but will try your suggestions tomorrow morning.

Thanks again.
