could you tell me which processes are GPU and which are CPu intensive?

Ok,  this was very clear.

I think that this is propably not the best choice  cause of 2:2 pulldown.

1 1 * * * * * * * * | 2 2  * * * * * * * * |

8 continous interpolated frames means 12,8 ms " fake" image and double artifacts than 24->60 (x2,5)

First of all, THANK YOU for your replies.

i am very glad i am talking with the developers of SVp:)

i also would like to ask you a few more questions about your project,


which works of svp kit are cpu intensive & which are gpu intensive
and how the program knows *where to work*

(maybe when choosing cpu profile during installation????)



2. if we have a weak cpu and we just care about judder free image ,
is it correct to choose screen refresh rate/2 and then play with 2:2 pulldown?

if yes ,how does this work?

after reading Mag79 post, i would like to clarify how frame interpolation
works in this case.

when choosing screen refresh rate /2 (30hz) is it (1,5x), 2m or 1, mode?

e.g
2m:

1 2 3 4 * | 5 6 7 8 * | 9 10 11 12 *| 13 14 15 16 * | 17 18 19 20 *|21 22 23 24 *| (x2) =

1 1 2 2 3 | 3 4 4 * * | *  *  5  5 6|..... (2:2 pulldown)


1m mode:

1 * * 4*|5 * * 6 *|7 * * 8 * |... (x2)

(x1,5) mode:

1 * * * * | 5 * * * * | 9 * * * *| 13 * * * * | 17 * * * *|21 * * * *| (x2)



and my last question.



3. Are there any minimum recommended settings?

i have tried most of the commercial players like splash pro,simHD in TMT, (cyberlink never worked for me)
but i could not change anything in their settings and i think most of them reduce resolution when the cpu loads.

i found many profiles from users , but i would like your *subjective* opinion about minimum settings 

thanks in advance

1)Frame Rate Change:


what's the difference in each setting?

24-->60 2m (1,5) means that svp kit interpolates frames from 24-->30 with 2:2 pulldown?
double frame rate is the  simple 24p-->48fps?
24-->60 1m (2,5x) means 24-->60fps 1:1
and which is the difference between this and 24-->60 (x2.5)?

if the desktop refresh rate is set to 60hz and we choose : to screen refresh rate which of the three interpolation methods occurs?

2)Recalculation of vector:

whats the difference between do not recaclulate & recalculate with blocks diving

this is one of the most cpu dependant feature but i cannot see what it really does cause of the GPU load

3)Processing of scene change:

whats the difference between frame repeating vs frame blending

i actually dont understand how  does this script work.

let`s say we have a 23,976 movie.

we have 1 2 3 4 5 6 .... 23 frames


when the screen is set at 60hz we have 3:2 pulldown
frames        : 1 1 1 2 2 | 3 3 3  4 4  | 5   5  5   6    6   | 7  7   8    8    8  | ...
desktop HZ : 1 2 3 4 5 | 6 7 8 9 10| 11 12 13 14  15| 16 17 18  19  20| ...

when we interpolate the frames what exactly happens? (where the interpolate frames occur)?



frames                      : 1 1 * 2 2 | 3 3 * 4 4  | 5   5    *   6  6   |  7    7     *    8    8  |...
refresh rate @ 60HZ : 1 2 3 4 5 | 6 7 8 9 10|11 12  13 14 15 | 16   17 18    19  20|...

Or all frames are fake/interpolated frames ???

1 * * * * | * * * * *| * * * * * |

( * are interpolated frames)




At the bottom of the settings there is a box:
frame blending to screen refresh-rate

if we check that box does this reset all other settings to have 100% interpolated frames to screen resolution?


I also would like to make one more Question.

For us who live in PAL countries (with 50hz TVs)
is there any way to set the frame rate to 50hz?
for example 24-->50 ?
or is it better to set it to double frame rate @48hz with 4% speed up?

Thanks in Advance
