"The FI isn't really needed for sports in my opinion from what I've seen so far" I first mentioned after not much time trying it out.
I hadn't seen enough really with good signals and had not tried the high setting. Well I just spent 3 hours with HDTV channels from very good cable I get from Charter on the high setting. As mentioned before, 8.5' wide 16x9 Hi Power now with the RS25. Running on normal lamp setting -3 with the iris and only 24 hours on new lamp. Certainly a bright, realistic looking image for sports and video acquisition. Also very revealing when less than a stellar broadcast. Some broadcasts are clean and beautiful and some are crap. I run through a Flea first and an Edge. Minimal settings on the Flea....+1 for mosquito NR, +1 regular NR and +1 block artifact reduction. Excellent performance at those levels with next to no loss of detail. Purists will probably cringe at what I say next about the detail enhancement level I am using with the Flea but I've spent hours with the split screen function comparing fine detail with the processed and unprocessed versions of the signal. And looking for any possible negative artifacts. I choose to run it at +13 most often....just 2 clicks below max. All it does is amazingly, cleanly take that beautifully "scrubbed" signal and really add incredible detail to everything. If there is anything negative going on I sure can't see it and even if there is something faintly, next to impossible to see happening, it's a tiny price to pay for the benefit gained in the images from the cleanest sources.
I watched much of game 1 with the Angels and Red Sox which had an outstanding feed, and flipped back and forth to the Nebraska & Missouri football game being played on artificial turf in the rain. Another excellent signal with great highlights with all the water and deep shadow detail. The frame interpolation on "high" did absolutely nothing but add a greater depth and increased sense of 3D to many of the angles, scenes & images. No loss of that great detail with the clean broadcasts, no other type of artifacts being added that impacted negatively in any way. The PQ reacted just as it would without the Clearmotion function on, to the variety of quality from all the various cameras and camera angles. Some scenes really were beautiful with their depth. No problem with baseballs and footballs being thrown across the screen. Or fast motion. Often the depth would impress on the sideline cameras just in close on fairly stationary subjects.
I tried it with the FI on "low". Since nothing negative seemed to be going on with it on high, nothing seemed to be gained in reducing any unwanted side effect. It was a negative effect actually in that the low setting did not have as much depth and 3D as the high setting.
If rumours are true and information correct that JVC will be tweaking the performance of the clearmotion function with firmware updates, maybe there will be even more across the board improvement as well, in addition to addressing what's apparently being seen negatively when used with 24FPS. I don't care about it for movies and most people here describe disliking the effect it has on them. But the experience of watching the sports programming and a lot of other channels and variety of programming for 3 hours with it on high no less, makes me want to continue. ESPN Sportscenter has really exciting, vibrant, 3D graphics that get more complex every year it seems, and these looked beautiful and more dimensional too with the FI on. I highly recommend checking it out for the sports fans here who will be watching more than movies with the new JVCs.
