Greetings,
I'm encoding the Lakers Dynasty DVDs and I was wondering if I could get some tips on encoding sporting events. I have encoding movies down to a tee, but sporting events are a different monster.
These DVDs have full games on them (all interlaced of course) and I want to encode them in Divx at the best quality possible (at about 1 gig per game which runs about 1:40 hours). I de-interlace the video with ITVC through gordian knot, and I do 3 passes with Divx at its Slow setting.
But I can still see some slight interlacing in the game, like when a ball gets passed or someone shoots a freethrow. Can anyone provide advice when encoding these things? Thanks...

Well, I'm still somewhat new to this, but are you sure your source is interlaced or telecined?

If it's interlaced (As you said), then IVTC is the wrong way to go about it. If it's telecined, are you setting "Force FILM" in DGIndex? I'm pretty sure that forces IVTC.

Content shot with a video camera should never be Inverse Telecined, as it was never Telecined to begin with.

See www.doom9.org/ivtc-tut.htm for guidance.

hmm, I've always been under the impression that Force Film was only to be done if the DVD is Film 90% or more. This Lakers DVD is NTSC so I automatically assumed to apply IVTC. I'll try forced film and see which is better. thanks.

Read the tutorial in the link. Your impression is incorrect. Film content is Telecined when converting from 35mm film at 24fps to 29.97 NTSC.

Your content is very likely not film.

You won't know for sure unless you look at individual frames.

Force FILM is an Inverse Telecining process.

If the content was shot by video camera, you should deinterlace and leave at 29.97fps.Click on the link. Then do some reading. All of your confusion should disappear, and most of your questions should be answered.

Knowledge is power. Get some.
