HD on big flat screens never blew me of my socks anyways (compared to the marketing mabo jambo they make about that).

We did first first tests with our new Bluray recorder and one of our HD documentary footage (1920x1080/25i/Sony HD-Cam).

Ha what a bummer. Looked like poor encoded DVD - blown up.

Flicker in dark passages, jitter, stutter in pan/tilt/motion, artifacts and what not.

Look allright as long as nothing moves, but with some motion the resolutin seems to drop in half.

O.K. we prbably did not understand the parameters or simply messed it up somehow.

Then I went to "Media Markt" (big consumer warehouse) and looked at 50 different plasma and TFT screen that show a "reference" Blueray.

Same game here.

You need have to sit back about 4 times the screen diagonale til things get better.
And now I have found out why. Your eyes canīt resolve the resolution at that distance anymore - there is a formula for that.

That is sitting in front of a 23 inch computer display, set to 1040x720 and watching a good PAL SD DVD is the same as sitting 4.5 meters away from a big flat Plasma and watching a HD Bluray. Your eyes canīt tell the difference only your brain (washed by marketing experts) belives it can.

The same thing was done with wine latley and caused a big media echo over here.

They gave some poeple 5 different wines (actualy it was the same cheap wine) an told them this a a expensive one and that is a cheap one and so one.

All of them swore to god that the "expensive ones" actualy tasted better - just because the brain thinks that a more expensive wine have to taste better. Tests in a CT showed it was clearly done by your brain.

I think the problem may be your Encode to BRD.

The purchased BRD i buy and watch on my TV look astounding.

All I know is my 42" Vizio Costco HDTV kicks some serious butt. Especially sports!
And forget this "sit farther back" stuff. I get right up close.

random.. but oh god.... watch Ratatouille on Blu-ray.. good lord... absolutely stunning film...

The quality of your image will really greatly depend on your source.. and your encode.. and finally the TV you're watching it on.

If your footage looks good on your editing suite, then it is definitely an issue with your encode. Also check the output settings of the Blu-Ray player.. make sure it is all setup right.

I also noted that 3D animation films look way better than real life photography, because there is no noise at all and less color to encode.

Also I did some encoding tests that weekend.

Mpeg2 doubles the file size but makes better pictures, motion is pretty smooth.

H.264/MPEG-4 AVC has (even with the best and carefully selectet settings) bigtime problems with noise in the blacks - wich leads to motion and block artefacts, including loss of detail in the darker parts.

VC-1 (WMV9) takes forever to encode an took already 3 hours for 5 minutes of footage- still not done (Mpeg2 takes 15 minutes for the same scene)

Iīm extremly picky because I worked as a colorist for several years so I look with a differnt eye at things that others probably don`t even realize.

As I said - if you sit back about 4 times the screen diagonale you will never see the things Iīm talking about.

The average Joe Shmock will be happy as long he got a big, flat, colorfull screen at home - over here most of the TV programms are still 4:3 and most poeple with Plasmas donīt mind to stretch it to 16:9 so it fills the entire screen. They don`t care if the faces get broad.

I told my nighbour that he can resize the wohle picture but he donīt want to loose the upper and lower portions of the picture - he said he can live with broad faces.

Will they care about 32000 colors is all the TFT displays can show?
Will they care about noise in the blacks?
Since we have Digital Terrestrial Television they got used to big block artefacts here and there anyhow.
