In simple terms, the script gets more aggressive as you up the numbers. +1 (x2) applies a fairly tame algorithim and hence a minor 3d effect. +10 is at the other end of the spectrum, hence it is a more complicated algorithm and applies an extreme 3d effect. The image on the +10 literally gives the impression that you are there in the movie, or a very 'soap opera' effect as some people like to call it. The only downside is that because the +10 script is very aggressive and complicated, it does tend to introduce quite a bit of judder, macro blocking etc. I tend to leave my motion2 on 6 as it provides really good depth to the image, a nice 3d 'pop' , hardly any artifacts and the video is damn smooth.

Bottom line, experiment with different settings and choose what you like. Your PC's ability to handle the motion2, the type of file, the resolution of the file etc all have a bearing on the quality of the picture. Experiment away!
3d effect? sorry, but, motion compensation algorithm doesn't have anything with perception depth.

since motion compensation should eliminate judder, either algorithm is broken or computer is too slow (at this point, I believe both is the case).

Ask the average person and they will tell you that motion interpolation gives the image more pop or an almost 3d quality. I realise technically this is not the case, just trying to illustrate a point. +10 does introduce unwanted artifacts, hence +6 seems to be a happy trade off.

How about adding 30p mode? It would eliminate juddering with 60 Hz monitors but still would be pretty close with 24p, and I assume it wouldn't be as CPU consuming as 60p mode.

that might be difficult to do so

IMHO 30p will be still juddering. I have few camcroders and Canon records 30p. Judders as hell withut motion2.

We do not plan to add this in the nearest future.
But for future versions we plan to add more supported framerates
I will note your suggestion to consider for future versions.

to BDX> adding 6 accurate frames to 24 is much more computing-intense task than adding 36 (you have much more freedom thanks to the imperfection of eye's motion perception, i think you even have to recreate each frame to get smooth 30p from 24p)

i have one question to add myself - is it possible to run fullHD motion2 on a passively cooled system inside a box with rather poor airflow? on http://mirillis.com/en/products/picture2.html minimal requirements are quad core...so i assume any kind of Atom CPU is simply not enough? My (really really old) Core 2 Quad Q8200 – 2.33 GHz usage is about 50% with fullHD video and Motion2 turned on, so maybe the new Core i3 2100T with 35W TDP or similar should be enough? next question would be the GPU that should be assisting...

Nope. 24 -> 60 is 5x to 120 fps, and than throw away half of them. 24->30 is mostly the same, but dropping not half, but 3/4 of frames.
So CPU usage would be the same in the part of motion analysis, but it would be slightly lower in the part of frame synthesis.
Also when interpolating to 60 fps you have 12 real and 48 interpolated frames, but when to 30 - real would be only 6, so overal quality would be worse.

It has only 2 cores, but by benchmarks overal perfomance is the same (http://www.cpubenchmark.net/high_end_cpus.html)...

Hard question when have no specific PC in the lab for tests.
The best is to try out and monitor the temperatures.
Using hardware accelration for video decoding should stress off CPU a little bit and lower temp.

Core i3 should be enough for Motion2 when using hardware accelerated video decoding.
It should run even with very high bitrate 1080p videos.
The NVIDIA 9500GT like gpu should be enough to run hardware video decoding and Motion2.

For Ultra 1080p option it still needs good quad core to run smoothly in all scenes.
