Regarding the M.150, which level of frame interpolation are you referring to? I have been watching 2 full movies in the last days, and skipped through all the fi-levels on the SIM2 to watch out for possible skipping. Usually I have the fi on high, but put it to low and medium for quite some time to check on skipping. I must say I didn´t notice any skipped frames on the M.150, no matter which fi level I was using. I stay with my verdict that I find the fi on the SIM2 pretty good and usable. On low, it is still a bit too stuttering on my huge screen, whereas on high it´s perfectly smooth, but with some blurring around moving objects. But no lost frames as far as I am aware of.
Well this is interesting because I think it is the same on medium and high as it is on low, except maybe on low, it only activates for slow pans and certain shots but not others? My understanding is...
Low interpolates 24fps to 48fps, but only for slow pans and certain shots. Otherwise it stays at 24fps.
Medium interpolates 24fps to 48fps all the time.
High is 100% the same as medium.
Am I mistaken? If you check the "info" screen in "puremovie" mode, with no frame interpolation on, it says it is outputting at 48hz. This is because they have are doubling the same frame in order to sync it with the LED timings, but it's the same as 24fps. In other words, the info screen will always show double what the framerate is on the M-150.
Then in "puremotion" mode with the frame interpolation set to "low," it says 96hz, which means 48fps (but only sometimes, I think). Then set to "medium," it still says 96hz. Then set to "high," it still says 96hz.
What is your image source? Can you check different sources/players? And which GeoBox do you use? Can it output 24 Hz? And have you activated the 24 Hz throughput? If not, the GeoBox will output 60 Hz, but with a 3:2 pulldown, so no good!
Or do you use a HTPC and have low frame repeat times? The madVR info shows you how often a frame repeat / frame drop is expected. Could this be the root cause of your problem?
So far, I have not tried any of this stuff. I am totally new to Home Theater, started about 10 months ago, and have had to learn everything from scratch to try to plan and put together this project with both passive 3D and quality 2D. I have literally ten thousand emails and phone calls etc in that time to learn so many details. I have come a long way but still ironing some things out. For example, I have madvr successfully working on my PC, and I just bought a pre-flashed 4K UHD drive to use with it, but have not learned how to make them work together. I have asked a few people for help but so far nothing. Meaning so far, the only source I have tested anything with is the Sony x800m 4K UHD player. Not the x800m2, but the original x800m I think it's called.
Really, that Vivitek´s FI is absolutely gorgeous! I always run it on high. Smooth as butter, and almost no visible artifacts at all. I haven´t seen nor heard of any better frame interpolation. I luckily don´t have a problem with rainbows, but if you are sensitive to that, it might be a problem. If you see them in 2D, you also see them in 3D, that makes no difference. However, as these Viviteks have RGBRGB 6-speed colorwheels, it´s the best possible colorwheel solution (for rainbows as well as for Gamut).
What type of colorwheel did the 2 DLPs have that bothered you?
How many lumens do you get, calibrated, from each Vivitek? The two models I had rainbow problems with were this, https://www.amazon.com/Optoma-…r-Projector/dp/B00MK39P92, the Optoma Hd141x, and the Infocus IN83.
Also, the only lcos I have seen is the JVC RS4500. Unfortunately it was just a demo of scenes I was not familiar with, except for one. Say there were 7 scenes demoed total. Six I was unfamiliar with, one I was familiar with. The first six, when I was watching I thought, "I completely made the right decision. The motion is much worse, and the picture is much noisier." But the one scene I was familiar with, I immediately became confused, not knowing what to think, because it seemed exactly the same motion and noise level as the M-150. I have heard some people say JVC made big improvements in motion going from the e-shift generations of mdoels to the NX line, which is where the doubt comes into play whether I would get just as good native motion with a modern JVC as with DLP, but perhaps a more powerful and reliable frame interpolation algorithm on a 2018 model than a 2012 Sim2, because of the improvements in processing power in that time.
