Telecine woes

[fmctm1sw]

After a lot of looking, I figured out why my videos seemed a little jerky during left to right motion. There is a distinct pattern of 3 clear frames and then 2 frames that are a little blurry. I figure this to be telecining. I've been researching different ways and pros and cons of IVTC. My question is, if I can properly IVTC my source videos, will I see any benefit since my DVD player will have to telecine it anyway to play on my TV? I know I will be able to up the bitrate a little since there will be fewer frames to process. But my main issue is the left to right movement that looks choppy.

If you have the eye, yes it will notice a huge difference. I use AVISynth for this, using the decomb plugin you have 2 functions telecide() and decimate(). telecide() will replace the 2 bad frames by copying good frames, framerate stays the same. Adding decimate() will convert from 30fps->24fps, something that doesnt always need to be done.

I dont know if you are using TMPGEnc to encode, which I do, but its IVTC blows, super slow and crashes alot on me, IVTC is what got me using AVISynth as its the best way to correct it.

Thanks. I was actually lucky enough to get a piece of movie that had a (pan?) from left to right. It had a brick wall in the background. I converted one to MPEG with TMPG without IVTC, then made one with IVTC. I can definitely see a difference. But you are right about taking forever. It's the first thing that came to my mind (and this was only a 25 second clip).

And as for the final product on my TV. Will it look any different?

I notice a difference on both interlaced tvs and progressive scan tvs. its worth doing.
