Project Property Settings/ Plasma TV's?

Hello All:

So sorry in advance for such a long post

My business partner and I have been shooting weddings together for over 10 years now and we both use Vegas to edit all of our material. About 5 years ago when we first purchased Vegas, someone in this forum gave us some Render settings and some Project Property settings that I saved as templates for all of our projects. And five years later, we still use the same settings and have never changed them.

The reason for this post is that just this past wedding season, we shot only two weddings in which the bride and groom had just purchased brand new HD Plasma TV’s.

The feedback that I am getting from one couple is that the quality of the video is not looking as good on their new Plasma as it did when they watched some of it here on my regular 32” Sony TV. The groom called to tell me that in lower lit or darker scenes, there appears to be pixelation and jagged edges especially in the scenes where there is motion. For instance, this was an outside wedding on a very windy day and the sun was going in and out of the clouds continually. The minister was holding a piece of paper and I am being told that the paper is pixilated and jagged as it blows in the wind. The same thing is happing during the shots of the limo driving away. Even though I do not know anything about Plasmas and LCD and how they relate to video, I have heard that there are some issues with motion. So I guess my question is: Is there anything that I should be doing differently with my Project Properties or Render settings if the final DVD will be watched on a Plasma or LCD TV to eliminate this issue. Unfortunately, I do not have a Plasma or LCD TV to recreate the problem to see what the customer is seeing, so I was just wondering if maybe the Field Order or De-Interlace Method in my Project Properties should be changed. Currently those settings are at: Lower Field First and Blend Fields.

Thanks,
Lori J

Interesting. I have a plasma as well as LCD and I make no special adjustments for either one and do not have the issues you talk about. I don't think one should have to make any adjustments!?

Now I'm playing back HD from a HD DVD player and that may make the difference.

What cam are you shooting with? Are you shooting HD, then down rezzing to sd?
How are you outputting you file(s)?

I experience this. I can watch a video made with Vegas through my ps3 shown on a 1080i LCD and it looks really good due to the uprezzing of the ps3. I can also play a dvd made via a standalone recorder (cam hooked to stand alone via firewire) and there are artifacts surrounding moving objects if placed in the ps3 and shown on the HDTV. If I take this same DVD and move it to a standard def TV, it looks great. I did not try playing that same disc via the recorder that is hooked up to the HDTV. I will give that a try tonight and see what it looks like and report back if necessary.

You don't have to render any differently for a plasma or LCD as you do for a CRT.

What your clients are reporting sounds like problems with their displays. For example, many plasma displays have issues with their deinterlacing filters, that manifests itself as "tearing" when certain parts of an image move. Essentially the display doesn't deinterlace those areas correctly and one sees the two separate fields.

The quality of the display and its electronics has a huge bearing on the quality of the picture, so you may see interlacing issues on an entry-level Pioneer, but not on a Runco. Likewise the problems with shadow detail. Neither plasma nor LCD displays can produce pure black, and depending on the settings (most people never properly calibrate their displays) that will highlight all sorts of problems near or below black level, especially in NTSC systems.

Colours and blacks aside, ther eis a problem regarding the project framerate versus the plasma reefresh frequency. In the context of the EX1's native 24p capability, and BD lacking 25p mode, I have this question - probably to PAL users mainly:

I'm about to buy a new 50" full HD plasma, and am faced with a tough choice between:

- Panasonic model, cheaper but lacking a refresh rate being 24 fps multiple, or
- Pioneer "Curo" model, optimized for 24p (72 Hz refresh) and much more expensive.

To put is differently: is 72Hz option in Pioneer plasmas (or even higher multiplies of 24, like 120Hz) worth the price premium? Or is 24p material played back on regular PAL HDTVs (50/100Hz) acceptable, motionwise?
