16:9 picture lower edge above the black border flickers on 4:3 TV

[Srivas]

Is there any setting to tweak before converting or is it just a lousy TV and you cannot do anything about it?
On computer screen everything looks great.

Or should I resize to 4:3?

Thank you.

What is the source ?
Does it happen on all discs, including commercial discs ?
How did you encode and author ?
What is your TV and player ?

I see, many factors are involved, I got a bit smarter already

So I did some research. My source files are progressive mpgs, rendered by mainconcept encoder to interlaced mpgs in Vegas and authored through DVD Architect.

TV is PAL/Secam. Checked the dvd with two separate players, same problem occurs. I have to get some commercial disk to see the difference, maybe its the TV after all. I'll do that.

One question arose, I just read one another thread, that as I understand now, there's actually no need to render progressive material to interlaced for a PAL TV, cause dvd player will interlace it for the TV and picture will look fine. Is that correct?

But then why when simply rendering as progressive, the picture looks pixelated (if thats the right term) on computer screen, not sharp, low quality. If I render interlaced and blend fields and add some sharpening, it looks much better on computer screen. Why is that?

Your computer is a progressive display. The player you are using is probably deinterlacing (badly) on the fly. You should not deinterlace, especially with blend fields, if you are going to watch it on TV.

Ok. So it means I should render as progressive and without deinterlacing, and then it should be fine. Am I correct?

Hello!

I got the problem solved. Actually my input material was from a new HDD Sony camcorder, so it was interlaced, upper field first.

So the flickering was from the fact that I forgot to change resolution to 16:9, so Vegas was rendering 4:3 and adding black frames to the video and that caused the flicker on TV. Also, I noticed that I was getting best results, when rendering to progressive and interpolate fields, picture looked more crisp and not so tiring for the eyes.

Although Im not understanding this. I mean, TV is PAL, interlaced, so why progressive video looks better than interlaced, when this is the native format? Is that the fault of crappy player?

So is that true that best is to render always progressive, so that you can then play those dvds nicely on computer and also on TV? Will it also be compatible with NTSC, is that dependent on player?

Thanks for the help.
