SD VS HD and color

[MacinMan]

As some of you know I'm relatively new to HD content as of Last year when i purchased my first blu-ray player, I've had an hdtv longer then that, but just used SD content until I got a true HD source and ota broadcast went to digital HD, etc.

Anyway, One thing i've noticed is SD video doesn't seem to deal with the cinema optimized settings I have this tv calibrated. e.g. many of my SD movies have a reddish tint that HD content doesn't have, or another example is SD content seems to show the yellowish tint that the warm color temp tends to have, while HD content seems to bring out a much better color depth and contrast when in warm.

What I have done is entered offsets for all color temps in the tv's service menu and I have entered the same set of offsets for both HD and SD content. For SD content I find using the normal color temp to look more natural then warm. While HD content seems to be able to take advantage of the warmer color temp and cinema settings much better.

Here's the question now. would playing SD content from an SD input maybe improve color for cinema settings or would it maybe work better to use normal as a whole for SD content. I know NTSC had color management issues compared to HD which is no longer NTSC. Any feedback would help. Actually to be fair the television station where i did my classes for broadcast production didn't switch to digital until last year officially it was still SD and before that analog. They started switching stuff like cameras and other pieces of hardware one at a time until it was time to switch completely to digital. I've noticed pure digital HD content has better results then analog SD or analog SD converted to digital etc.

I recommend you get your T.V. professionally calibrated..... if you're not up for that, get the DVE Basics disc, and if you're not up for that, at least check the "Share your settings" threads and find your T.V. model etc.....


Color reproduction is certainly a huge selling point of Blu-ray, but to have the discrepancies you're having, I would assume you're over-correcting.....

By "warm" are you saying you're using the stock settings in your T.V. like

Warm
Vivid
Sports
Cinema

etc???

If so..... you really should have your T.V. calibrated.

Actually in my TV that is calibrated for HD picture the SD picture looks far too warm in colors. But I have been so lazy with the low quality DVB-C TV broadcasting picture that I've used the same HD settings for all material.

Most of what I have done is from information found on AVS forums.

First of all:
I used Drod6's offsets for the service menu settings to correct color reproduction out put and the values assigned to how much of which colors are mixed etc. Then I used his recommended settings for the user menu as well. I also downloaded their AVS HD calibration dvd they provide for free. and ran that . Actually it's a blu-ray structure that contains avchd video. and avchd compatible players treat the DVD like a blu-ray disc. As far as color various I think it's so much a source related issue at this point as the calibration disc after i've made the mods to the tv's service and user menu entries check out good. And i've noticed the same imperfections even when played on the laptop ripped from DVD to an mpeg 4 as the movies i copied didn't have digital copy versions they were too old before that was an option.

That was my whole question, thank you! I know I've already calibrated the display outside of using meters etc. but it seems like SD content and HD content use a different color palette, and the two don't mix well. In fact it seems that plasma tvs do color so well they magnify color defects much more then Lcds. I did enter the offsets for both HD and SD so maybe playing SD via an sd input e.g. component vs HDMI would give me better results for SD content as component will be using the SD offsets instead of the HD ones.
