Interlacing issues only, understand, intended, issues

andy

I've read everywhere that if I'm gonna make a DVD that's intended to be viewed on TV I should leave it interlaced.
Fine, I understand that, it sounds logical to me, but I can't make it work, I still get the ghost effects and a very jerky, unsmooth play.
The only way that I have made it work is to use deinterlace filters or Bob. This is okay for capturing movies or TV-shows from a broadcast but when it comes to sports it doesn't work very well. I know it's the quot;wrongquot; way but it's the only way that works for me.
I have tried using Avisynth and changing the field dominance and field order, swapping fields, separating fields, etc.
Nothing works.
For example, I have a hockey game recorded from the Olympic Games that I would like to edit and burn on DVD for viewing on TV.
Can anyone tell me how to do that without using deinterlace filters or BOB?
This is one example of a Avisynth script that I thought would work but didn't:

AviSource(quot;clip.aviquot;)
AssumeTFF (since the clip was top field dominant)
SeparateFields
Weave
fadein(10)
fadeout(10)

What am I doing wrong?

Thanks

You can cut that script down to :
AviSource(quot;clip.aviquot;)
fadein(10)
fadeout(10)

I'm not familiar with Fadein/out but other than that I dont see a reason why it should not look correct on TV. When encoding you will have to tell the encoder that the source is interlaced and TFF.

You may also want to post a small sample so others can take a look at it and see if there isnt a problem with the source (though normal sport footage shouldn be more than normally interlaced).

Okay, I'm using Encore to do the encoding for me so what you are saying is that it's the encoder that messes up the fields?
Thanks for your fast reply!

Well I dont use Encore but you can try with QuEnc or HC - which are both excellent free MPEG2 encoders with no bloat. You can try to encode a small sample with those and find if its really Encore messing up (or not set up properly).
They require YV12 input. Just add ConvertToYV12(true) to your script (last line).

You can get QuEnc from here
and HC from here HC_Encoder/

Thanks!
I'm gonna try them if I can't configure the encoder in Encore.

what are you playing back with?  a lot of media player software does a crappy blur deinterlace for you (this is SO DAMN ANNOYING when trying to watch DVB stuff through TV out...).  you might find that when you burn a DVD of your stuff it'll play alright on the TV.  use a DVD-RW in case i'm wrong though...

I'm playing back with a hardware DVD-player for viewing on TV, I don't have a TV Out on my computer yet, but thanks for the info so I know if that becomes an issue in the future.

Ok, Thanks!
It worked fine that way, it was a field issue problem. The encoder started with the bottom field while my clip was upper field dominant.
Thanks again!
