A bit more on frame interpolation with the Epson Home Cinema 6500 UB

Greetings and Merry Christmas (It just turned Dec. 25th here, right before I posted this.)  And happy holidays.

OK, a bit more on the epson’s frame interpolation.  As I have answered, in a couple of comments, this is a work in progress.  I’m learning more each day.

In my last blog on the Home Cinema 6500 UB, I found that both Frame Interpolation, and 4:4 settings, when feeding a 24 fps source, have some real issues.  I won’t repeat them here.  In a comment I answered about a half hour ago, I pointed out that the projector may well perform completely differently with a 30/60 fps source, and would try that.  

Mind you I’ve only spent 15 minutes with my PS3 now set to Not output 24fps.  I’ve been watching repeatedly, several scenes from Casino Royale, mostly the same ones I watched when studying the frame creation with the PS3 outputting  24fps .  The Epson is now showing a 60 hz input, as desired.  

Bingo!   With frame interpolation on (Normal setting, there’s also Low and High), once again the extra depth appears, as is frequently being reported on all sorts of devices with 120 fps frame interpolation, and it looks like that depth is going to be considered (right or wrong) a typical result with frame interpolation  This time around, however, the jerkiness is effectively gone.  I’m still spotting an occasional “jerky” artifact from time to time, but, considering, that when looking, nothing is perfectly smooth, I’d say overall, it’s smoother than a straight 24fps in/out, and smoother than what you normally expect from 3:2 pulldown at the standard 60fps.  I’ve seen this before on the other projectors with frame interpolation on.  Let’s face it, there are going to be motion sequences that confuse any “intelligent” frame creation.  Of the four “top of the line” 3LCD projectors, only the Mitsubishi HC7000 has frame interpolation, without creating modified frames between the original ones.  

So, That’s really good news.  I didn’t originally notice any issues when watching football all day, last Saturday, with frame interpolation on, but I was – truly – watching football.  I was not paying any attention to the picture quality – beyond – “looks great”.  Therefore, I believe that the projector’s performance for sports is essentially the same as for movies, as long as you don’t feed the projector 24fps.

Again, I’ve just been playing for less than a half hour tonight, and plan much more attention to figuring out what works best, and what doesn’t for different types of viewing (content).  

I also plan to compare performance in the modes I find work best, with the Panasonic PT-AE3000, so we can get a pretty decent idea of which projector is better at what.

This is fun,  as I start moving up the learning curve about standard and creative frame interpolation, and the impact they have on the viewing experience.  Since this is the first generation of projectors with frame interpolation, most of us projector reviewers are probably well behind the learning curve, compared to those that deal with LCDTV’s and Plasma’s – since frame interpolation started appearing at least a year earlier.  

I’m moving the Home Cinema 6500 UB back into my main theater.  I think I’ll start with the first 15 minutes of The Dark Knight, but this time without 24fps.  Best of both worlds?  And, I’m now wondering, as I write this, will the speed choice for Epson’s frame interpolation – low normal high – affect the depth differently? That would be cool, you could basically dial in the amount of depth you want!  Hmm…

OK, I know you’ll all be anxiously awaiting my next blog, but don’t forget to open your presents!  -art
