ReClock DirectShow filter : try it !

[ookzDVD]

@ogo,

The latest one 0.99d is very stable on my system,
all are working well. Thank you for your great work.

PS. to be honest, even I can't notice any difference between use/no use the ReClock, while playing on PC or TV use TVTool, even I've followed all the guides.

I don't like to cause strife either. But I've uninstalled it as I found no use for it. It made no significant difference for me neither. The speedup/slowdown stuff would only come in handy for recording to VCR for me.

But I am sure it may help on some others systems.

It certainly makes a difference for me. The latest version works very good except for occasional stuttering with ZoomPlayer 3 beta 5.5. It goes away if I pause and resume but it is very annoying. Great work OGO!

[billou2k]

It definitly improves the playback on both tv and monitor!
excellent travail Ogo;-)
I had quite many problems with version 0.99c, so I followed your advices of installing directx9 with 0.99d and that's much much better.
Now with the latest version I could juste notice a few dropped frames from time to time but that's nothing compared to playback without reclock. I still have to test more material but what I tested was ok.
Ill tell you if I discover problems.
thanks a lot!

OGO,

Just to update... still working perfectly on my system and it has made a HUGE improvement. Have worked through several DIVX and DVD's with no problems!

Ogo, if the latency increases to past MaxLatency when using "audio-slave mode", will Reclock still add/drop AC3 frames out of desperation? There are some areas of certain files where it is very difficult to keep sync... it seems to add/drop a few AC3 frames there consistently. Perhaps if I increase the MaxLatency SPDIF to past 100?

Also, the only tiny issue I have is the following... when using default WaveOut, I can switch from PCM to SPDIF in real-time during a movie with no problem. Using Reclock, once I've started a media in PCM, I need to shut-down Zoomplayer and restart (not just re-load media) for it to recognize SPDIF.


OOKSDVD/ODDBALL --> I don't notice a difference on 98% of my film, but just on certain very difficult panning scenes (even then, they are only microstutters for which you have to be slightly obsessive-compulsive to notice). I could post certain clips that are especially difficult to play smoothly, however Reclock seems to manage them fine!

Ogo,

Just to clarify... when I switch from PCM to SPDIF on the fly, reclock actually registers it as "AC3 Passthrough" in the properties, however my system/soundcard does not seem to reset itself.

Yes, it does ... You can increase latency a little bit but you will get perceivable desync in this case.

Yes, it's called dynamic reconnection in DirectShow and it's not implemented yet on my filter. It's on my TODO list !

A good way to find a difference is to use a 100hz TV with some motion compensation processor that tries to interporlate frames from 25hz to 100 hz (Philips TV's do that -have a look on "Natural motion" articles on Philips TV sets-). On such TV's if frames are skipped, the motion estimator get confused and results are catastrophic. I can understand that on a monitor or a standard TV it's not always evident to see what reclock does. However to convince yourself you can play a 23,976fps film on a monitor at 75hz, or a PAL TV, and you will see the results on panning scenes.

I have another version ready with corrections for AC3 that correct all the remaining problems. I you want it now just let me know If not i prefere to take the time to add a few features like videocard selection, dynamic reconnect, and it will be ready for 1.0 And i still have that damn problem with Cmedia soundcards SPDIF

What you experience is the problem of "permanent stuterring" i describe in the "known problems" section in my website. The solution for this implies to write another filter in front of the video renderer, but i didn't found the energy to do it yet ...

Couldn't you do it the way you change different PCM formats already? I mean when you see a new media type with spdif and it was PCM previously, just reset everything inside the filter and start to use the digital output.

Frame rate interpolation would be a good idea, but would require another filter just before the video renderer. Quite a lot of work (i think video interpolation require motion estimation, etc ....)

No, motion estimation is one (and the slowest) posibility. Dynapel produses a software called MotionPerfect which does the interpolation with such advanced algorithems. It is realy slow and the results are not very good in some situations. In most (all?) situations it is better to do a simple average calcualtion like (picture1+picture2)/2= picture1.5.

As already said I have written a frame Rate conversation utility for AVI files, and the results are good in my eyes.

OGO... I wouldn't mind a copy of the interim Reclock until 1.0 is ready .

Bring it on! ;-)

Ok, i've put version 0.99e on my website. It only fix problems with AC3 SPDIF

[supAdrag]

wow first post!

well after several hour of trying to get ReClock running (which i really want cuz i can see the advantages with it) smoothly on my system i give up, i don´t know whats wrong and i don´t know what to do cuz when i run with reclock it just makes the clip even more jerky and stuttery than before, i think i have tried everything i could possible think of but still the same problems so maybe anyone can tell me if it has something to do with my hardware....here´s my setup (this is for my standalone mediaplayer)

PIII 500Mhz
128 MB RAM
Windows 2000 PRO SP2
Geforce256 DDR (Detonator 41.09)
Creative SoundBlaster AudioPCI 128 (Latest Drivers)
Zoom Player 3.0B4
FFDShow 20030103
DirectX 9
ReClock 0.99d

TV Out with TVTool to my PAL TV...

thanks!

yeah...you think that´s the problem....cuz i can play all movies fine without reclock (except for the problems reclock are supposed to help with), how much CPU power does ReClock actully take up?

than try hardware resampling, even if it's not recommended...

But if your sound card can handle it properly, it will give you optimum quality sound.

maybe it's a lockup that occurred on slower PCs during clock estimation (<=800mhz) - even though it should be fixed from version 0.99 and higher...

I am having the same problem, but only when I watch it on my computer. Here is my hardware:

1.2 Ghz Celeron
256 MB RAM
Windows XP
BSPlayer / WMP
DirectX 9
ReClock 0.99d
Monitor 60hz refresh rate
Playing back exclusively 23.976 fps

I'm not sure the rest because I'm not there right now but it's a Toshiba laptop (i.e. everything comes built in). DivX plays reasonably smoothly without ReClock for me, except a couple days ago I tried using the built in S-VIDEO (I think that's what it is) video out thing on my friend's TV and it was ever so slightly messed up. I installed ReClock, now playing back just to my LCD gets a little jerky (like, I look at the filter and it hovers between 50 and 150 ppm, what I understand is that you want this near 0, but it never gets there... like at least in 10 minutes it gets better sometimes and worse sometimes). I tried my system with reclock on my TV out though and it's beautiful. Like really good.

Is this because my monitor is not a multiple of 24? I was under the impression that ReClock would work best with a multiple of 24 or 25 but that it still helps otherwise. Is this true? Also, is it possible to change the refresh rate of all monitors? Because I was playing around in display properties and for my monitor (in the location I found) 60hz was the only choice. Is there another way to change this or am I stuck?

tried it, doesn´t change anything...

[sillKotscha]

best proof that it has nothing to do with ReClock
