The best - and recommended method - is for the player to decode the audio to PCM which then allows ReClock full control over resampling it. It has two ways of keeping the audio in sync. It's doing that *all the time* so you shouldn't have a situation where you suddenly find them out of sync. ReClock works by adjusting the audio (by resampling it) so that it is always in perfect sync with the video, regardless of what rate that video is. I tried reclock with bitstreaming, it just leads to audio drop outs after several minutes when the video resyncs. Not ideal if you have a nice HD audio supported Amp, bit of a waste to just send PCM. Reclock can get around this problem by decoding the audio, but then you lose bitstreaming. On ATI cards, the 2 lines remain near-parallel throughout. Personally this kind of stutter irritates me, my ATI card gives me stutter-free playback, as far as I can perceive anyway, as the ATI card outputs correctly at 23.976.īringing up the render stats on Media Player Classic or Shift+3 (I think that's the combo?) in MediaPortal whilst playing any 23.976fps material at 23Hz on Nvidia, will show a graph where the video clock rises gradually for several minutes, then slams back down to resync - this is where it stutters. Afterall, 23.976 fps material output at Nvidia's wrong 23.971 will definitely cause stutter, it has to to keep up with the audio. This is definitely stutter caused by A/V sync and not the typical artifacts of 24p.
