I promised a while back I would look at the Avia II motion tests and report back on how film mode does or does not improve deinterlacing of 480i material.
I thought about not posting these findings because:
A. I am a complete amateur and do not know what I am doing
B. I don't want to trigger a bunch of rumors
C. My setup is pretty low tech anyway
So take this for what it is: one idiot's test with an old (standard def) DVD player.
I am sure I am overlooking some important factors.
DVD Player is a JVC XV-N50, connected to the Samsung LN40A750 via component. (Firmware 1004)
Tried each test 3 ways:
- With DVD player outputting interlaced, 750's film mode OFF
- With DVD player outputting interlaced, 750's film mode ON
- With DVD player outputting progressive
(In all cases, AMP off, noise reduction off, edge enhancement off, black enhancement off, etc.)Moving Zone Plate 2:3
When the DVD player outputs 480i, this basically tests the TV's deinterlacer for film;
when the DVD player outputs 480p, it tests the PLAYER's deinterlacer for film.
In both cases, the set has to scale to 1080.
- The vertical resolution (as seen on the horizontal wedge) was very bad in the first configuration (film mode OFF).
- With film mode turned to Auto, it was marginally better, but not by much.
- Switching the DVD player to 480P was WAY BETTER.
--> Set does not deinterlace film as well as the DVD player; film mode helps a little but not enough.Moving Zone Plate Video
- The set did a so-so job when the DVD player was set to interlaced output.
- Film mode off/auto made no difference. (I guess the set was able to identify the material as video.)
- The DVD player completely hosed this when set to progressive.
--> The TV deinterlaces video better than the player. Film mode on auto does not seem to errantly detect a film source.
I noticed that my DVD player did not correctly identify the source as video (it has an indicator which tells you if it thinks it is dealing with Film or Video). But even manually overriding the settings to tell it the source was video, it was still a complete mess unless I let the TV handle the deinterlacing.Conclusions:
What does all this mean?
- Clearly, my dvd player does a better job deinterlacing film than the 750 does, at least when it comes to moving wedges.
- Film mode does not seem to do harm when left on auto.
So for now, I have my DVD player set to 480p and film mode set to auto (The film mode setting will have no effect with DVD's, since I have the player set to 480P. It may or may not offer some help with digital cable, but at least it is doing no harm.)
The real test would be to look at some actual material in all the various configurations. I will try it soon, but right now I have kids in the room saying "Dad, when are you gonna stop looking at those circles and let us play Smash Brothers."
Remember that I am an idiot, and don't assume this really tells you anything about how good/bad the 750 series is!
Please, others try this, or point out if I am ignoring an important factor.
I am aware that CNet gave the 650 a pass on a similar HQV test, as well as for 1080i material. I am hoping that others will run some of these tests and share their results as well.
Edit: Same results on FW 1008
