The purpose of ReClock Directshow Filter is to definitely get rid of jerky playback of video material(AVI, MKV, DVD, Blu-ray, etc) on a PC or a PC connected to a TV or Projector. Reclock can also fix the so called PAL Speedup. It's a DirectShow filter which is loaded in place of the default directsound audio renderer.

In response to Vosya below concerning the System Clock please be advised ReClock calls the 'QueryPerformanceCounter' ioctl (System Call) to confirm the APIC tickrate/clockspeed which runs at 3579545 Hz and therefore equates to 3.57 Mhz. This is not a bug. There are several timers exposed by the Windows Native API such as RDTSC, HPET, APIC and the ACPI/PM timers. All of these timers operate at diffenent speeds which creates a real headache for programmers who need to use a timer as a reference point for calculations requiring high precision. If you're interested here is some more information on the APIC:

ReClock is the best software available for removing 3:2 pulldown judder and correcting PAL audio pitch issues. In short it detours the usual way that DirectShow calculates a reference clock for A/V sync and by extension removes the horrible judder from running 23.97 fps content on a 30/60 fps display. If you want silky smooth video playback with no audio distortion then setup ReClock with MPC-HC x86 under Options > External Filters > Add Filter, install and register madVR then setup the auto refresh rate switcher in either MPC-HC or madVR (they both support it) so that 23.97 fps switches to 24 Hz, 25 fps to 50 Hz and 30 fps to 60 Hz. Add the presentation parameters in madVR under the display configuration as 720p24, 1080p24, 1080p60 and so on. Make sure you enable the DirectX hack for 24/50 Hz content as well. If you follow this you will have perfect 1:1 playback with no dropped/repeated frames. You can even enable WASAPI Exclusive output for bit-perfect audio playback. SPDIF/Toslink is also supported. For anyone wondering about SVP - this is not the same as ReClock because SVP uses interpolation and V/HSync targeting similar to the FRC in your TV. Hope this helps! Thanks to the developers for this excellent software!

Jan 31, 2017 Version: OS: WinXP Ease of use: 5/10 Functionality: 5/10 Value for money: 5/10 Overall: 5/10

after further evaluation I had one crash only when using re-clock and heard for the first time clicks and pops but I don't know I never checked it free clock was responsible so this is unknown, as for smoothing video no effect I still have jitter this is on my quad core with my high-end Nvidia . SVP is still the main smoothing software in use taking me to 60 frames per second. I find re-clock doesn't make any changes to what I already had.for the most part motion to technology in splash Pro seems to be the best but has slight artifacts problems but overall is the winner over everything I've tried. Splash Pro is working hard on their sound but I prefer using the true AC three filter which splash uses their own for 5.1audio but it does work. I'm not sure but it looks like I might be uninstalling re-clock I might wait I might not I'm not sure at this moment. I know it cannot be used on some files but overall it has been fairly stable. I will be watching for new version some new idea could pop up. I still think the author very very much for letting me try to get rid of the jitter but it's still there.

Jan 12, 2012 Version: 1877 OS: Windows 7 64-bit Ease of use: 10/10 Functionality: 1/10 Value for money: 1/10 Overall: 1/10

I'm just testing re-clock and the author in his writings addresses the same thing that has drove me crazy no matter how powerful my computer is I still get crappy video. I read your readme file and I thought here is a person that is thinking. Certainly anyone the right software is thinking but I've never actually read anybody's words before, hee hee.oh the rating system ease-of-use functionality and so on I cannot comment and don't think it's fair you should force an answer because I can't give one so they're just random numbers basically. Maybe later I can give a true rating.

I can't tell yet what's going on if it's really working I can't really notice but everything in my computer is new and it is running it is green or yellow it's doing apparently what it was written to do. I'm still so impressed with the author for trying to do something about this video issue and I'm very impressed and will continue testing. If I can help I will definitely try.thank you
