I´m the next one who will replace his Athlon...  smile

Regarding 720p50 from satellite: when video stuff is broadcasted (sports, news, shows etc) all of the 50 progressive frames are different. For films that were originally recorded with 23.9.... frames per seconds broadcasting stations do the following. The 23.9... fps material is PAL-speeded up to 25fps and every frame is shown twice to reach the 50 fps for broadcasting.

You say that we should restore original frame rate before using SVP. Without SVP I successfully did this with ReClock. But with SVP the use of ReClock gives strange results because ReClock is placed behind SVP in the DirectShow graph. So I searched around and found Avisynth´s "SelectEvery" (http://avisynth.org/mediawiki/SelectEvery). By virtue of the documentation it could be used to get rid of the frame duplicates, couldn´t it? But then we SVP-users have the problem that the Avisynth-section of ffdshow is blocked by SVP. Could additional instructions like "SelectEvery" be entered somewhere???

In a perfect dream SVP would detect video and film mode within the 720p50 material automatically and would call "SelectEvery" only for film based material.  big_smile

I dont think so, I know that!
but you system can smooth video up to 720p at simple settings, even Atom-based system can smooth video, MAG79 confirm, watch test result in forum svp-mark, first message
I am interesting svp-index score, please, press CTRL+SHIFT+G while playing video and show screenshot with GPU-ON and GPU-OFF

Wait for a Bulldozer, after his release Sandy Bridge should be cheapper  smile

OK, I played around with 720p50 material from our german tv stations. without_svp.jpg shows a screenshot with SVP stopped. All frame rates (in decoder, in ffdshow and in the evr) are around 50fps (as they should be). gpu.jpg shows a screenshot with SVP (gpu mode) turned on. The decoder and ffdshow input frame rate is 50fps. The evr shows 60fps. So everything is fine here except for the video stuttering due to my slow machine. Now it becomes a bit more interesting. The screenshot cpu.jpg, which shows SVP without gpu-acceleration, proofes that the gpu-acceleration is generally working. Because without it you can see that even the decoder isn´t able to keep the frame rate at 50 fps. But could you please tell me why the frame rate of the evr goes wild? It oscillates between 40 and 120. The screenshot shows for example 118.66 fps. Shouldn´t it be limited to 60 which is the monitor refresh rate when SVP is configured with "To screen refresh rate"? This strange behaviour results by the way in a number of message boxes popping up (see msgbox.jpg).

Well, here is another, more general question. When I think about the small hd resolution which is broadcasted with 50 frames per seconds, which is fine for video stuff, I wonder how films are handled, whose frames (speeded up from 24 to 25) were duplicated to 50fps. Does SVP first restore the original 24 frames (somewhere on your website I saw ReClock) and then secondly smooth these 24 frames to whatever is configured? Or how does SVP handle this case?

Thanks a lot for your good work, the infos and your patience,  wink

So, you guys think that my cpu is too weak? To be honest, I never felt happy with that one, but nevertheless hoped to get into 2012 with that (especially after tuning the old stuff with a new graphics card). Maybe I´ll replace my whole system with a hopefully more powerful Sandy bridge.

did you install OpenCL driver with catalyst software?
did you run svpmark? gpu-score and cpu-score are equal?

due to gpu-accleration I want to tip that it work but in 50% of cases bring a bit performance
gpu-accleration visibly at full-hd cinema with hard settings

OpenCL was part of the big Catalyst installer package. Because I don´t yet know how to interpret the SVPmark results I´ve attached them (one with OpenCL on and one with OpenCL off). From my amateur point of view the values of cpu and gpu are not that far away as I had expected. Is this normal behaviour? What seems to be the bottleneck of my system?

Hello, Wolpers.

1. First of all you should check item "Core2Duo profiles" when install SVP (pic).
2. After change ATI/AMD videocard to nVidia you must to uninstall all old video-drivers. Use special utilies for complete remove old drivers from your system. After that install nVidia WHQL-driver 275.33 or oldest. New ones has OpenCL 1.1 which are not completely supported by SVP yet.
3. At any time you can run SVPMark test to compare results with and without GPU.

Good luck

Thank you, MAG79, for the hint regarding the drivers. But due to some other disappointments I have removed the whole Nvidia stuff from my pc to give the ATI 6670 a second try. By the way I tried both Catalyst 11.7 (as stated) and 11.8 without the expected GPU acceleration boost? Do you have any additional hint for that graphic card?

Best regards, Wolpers

Hallo guys,

because my TV gives horrible results when doing motion interpolation, I´ve installed SVP 3.0.3 the big package) to let my pc do the job. It is an Athlon64 X2 3000 with an ATI 6670 (Catalyst driver 11.8). When SVP is turned on the cpu usage goes to 90-100% with the effect of a stuttering playback. So I tried the OpenCL option which surprisingly doesn´t improve anything. Suspecting that Nvidia´s CUDA is supported much better, I tried a GT430 as well. But with the Nvidia card the amount of stuttering is even higher.

Therfore my big question(s): shouldn´t the GPU-acceleration lower the cpu usage, should it? Why is there obviously no difference between GPU- and CPU-acceleration? Or am I doing something wrong?

Thanks in advance and best regards,

Wolpers
