DV (AVI) to MPEG2 (DVD)

Hi!
I have capture in dv format some videos from my cam (Sony TRV60E PAL) and i want to render them to mpeg2 with the best quality.
I have some questions:

1)The videos are interlaced and i manage to de-inter. them with Vegas but i dont know which is the best way to do that (lower-bottom field - deflicker - motion blur etc). Anyone knows something more?

2) When i render them the motion of the mpeg videos isnt good. When i use WinDVR i change motion vector to Vert.32/Horiz.32, and the motion is better. How can i do that in Vegas?

I have do alot of search in the forums but...

Which are for u the best render settings
for dv (avi, interlaced) to mpeg2 (Dvd, best quality, de-interlaced)

My english isnt so good so please give me some analytic instructions - answers...

Thanks a lot!!!

I don't know why you want to de-interlace your video to start with. As far as I know this in itself is going to cause you problems with motion even before you go to mpeg2.

All I do is render from standard AVI to mpeg2 using DVD template. For best results make certain everything is at 'best' ie maximum bit rate 8 MBits per sec.

This should give you pretty good results. If you still feel you're not getting the quality you want I'd start looking at the quality of the video before you encode. Noise is a bit cause of poor mpeg2 encoding results.

You may get better results with a third party mpeg2 encoding but you will have to pay for them. TMPGEnc is my favourite although you have to do a bit more work to get ouptut that DVDA will accept. There are many others available, ProCoder etc.

In my humble opinion the Main Concept encoder does as good a job as most with good quality source others seem to perform better when the source quality is not so good.

No i do de-interlace during mpeg2 encoding, but vegas has some settings about it and i dont know what is better....

I have good results using DVD template, my problem is that the motion is not so good, it is like 'slow' motion, it something about motion vector like windvr (or these i & b-frames) but i dont know how to fix it... i would like to have more smooth movement!

Why are you deinterlacing?

You shouldn't have to deinterlace IF you are using footage YOU shot.

However when you use other sources, sometimes you may want to. Perhaps the following site with give some answers; what interlacing is, how to fix it. Doing it when not necessary is a step backwards you should probably avoid.

I think by motion you mean a strobing effect.....your picture is jerky.. is your field order setting correct..

hm... my cam has 2 modes for shooting... progressive and interlaced .
With interlaced videos i see on pc-monitor these 'lines' when it has some movement.
I want to remove them so i have to deinterlace... or not ??? I set vegas to deinterlace when i render the original videos to mpeg2.. is it wrong?

I want avi videos to look good on my monitor when i deinterlace them and render again as avi.
There is not need to set vegas to deinterlace when i render to mpeg?

The other issue is that the mpeg2 videos looks to have some kind of motion blur in quick movements ...

How can i know which field order i must choose?

I think I have the same problem as you with my dv.

If you don't choose 'reduce interlace flicker' you get weird lines on fast movements right?

And making them mpeg2 with reducing interlace flicker produces weird movement of strobing. The mpeg2 looks alright though on my monitor, but played on the dvd player its all stuffed up.

If you shoot standard (interlaced) video, and you are going to view the result on a TV (rather than a PC monitor), do not interlace.

farss had it right: just render using the standard NTSC (or PAL) DVD template, and set the video encoding rate to 8,000,000 bps. Leave everything else at its standard setting.
