The purpose of ReClock is to definitely get rid of jerky playback of AVI and MPEG material on a PC (or a PC connected to a TV). It’s a DirectShow filter which is loaded in place of the default directsound audio renderer.

Codec : ReClock DirectShow Filter 1.7 beta 4

It provides a new reference clock that is locked to the video card hardware clock, in order to ensure that frames are played at the exact speed of what is expected by the video card vertical sync.

ReClock also provides a frame rate adaptator for media files that do not match a multiple of the video card refresh rate (ex: playback of 23,976fps IVTC NTSC on a PAL TV). Finally it is an audio renderer with hardware or software rate adaptation in real-time, multi-channel audio, and dynamic range compression capabilities.

Known problems and issues in ReClock DirectShow Filter 1.7 :

- ReClock may not correct the good video clock for videocards with dual head capabilities.

- On Windows 98, ReClock cannot always see that you change resolution.

- Graphedit cannot save a graph with ReClock when it is selected as active clock

- Morgan Stream Switcher does not work with ReClock (won’t load if ReClock is used)

- VSync correction and frame rate detection will not be possible when playback of DVD.

Changes in ReClock DirectShow Filter 1.7 beta 4 :

- (not tested) fixed 24 bits kernel streaming

- PCM audio support for Lynx audio card (and probably other soundcards)

- fixed a problem with file name detection of DVR-MS files

- improved media framerate late detection

- fixed compatibility problems when other filters in the graph make use of SSE/SSE2

- fixed audio clicks with new resampler under some conditions

- fixed dropouts with kernel streaming audio on Audigy cards

- fixed refresh rate detection problem with some newer ATI cards

- fixed partially monitor change detection problem in multi-monitor context.

- focus on player should not be lost anymore when launching the notification script

- won’t load anymore inside explorer process (

- fixed a deadlock that would cause a player freeze

- (unfinished) ReClock won’t load anymore in a filter graph

Changes in ReClock DirectShow Filter 1.6 :

- you can now allow ReClock to load only with some players/applications.

- tray icon can be disabled with config app

- built-in framerate estimator is now compatible with Trimension DNM

- improved builtin framerate estimator

- added new choices in adaptation menu

- ReClock will no more display a crash dialog when the code responsible

- fixed problem in video card detection at startup in multi-monitor config

- fixed bugs that would lead to a crash when video card detection goes wrong

- fixed a bug in automatic monitor tracking

- fixed a bug in refresh rate detection that could be false sometimes with some NVidia cards

- fixed a bug in crash situation when the crash dialog that would not always appear

- fixed a bug in PCM 32 bits sound handling that would distort sound in some rare cases

- fixed a bug that could cause a crash if event notification was enabled and player was in disabled players list

- reduced dramatically memory footprint of ReClock especially when multichannel audio

- compiled with VS2005 and latest SDKs

- other various bugfixes
