  • sync problem

    I've got a weird sync problem that I'm hoping somebody can help me with. This happened to me one other time a few months back but hasn't happened again until now. I'm hoping I've just mistakenly hit a key/button that I can quickly reset. Here's the scenario... I'm editing to a piece of music where I need cuts to occur at specific beats. If I start playback a couple of seconds before the cut I'm looking at, it plays in sync. If I go back 10 seconds or so, it then plays out of sync and the cut occurs before it's supposed to ahead of the beat of the music. It's really strange...

    Like I say, I'm hoping I've just accidently changed a setting that makes it out-of-sync. Any ideas? I'm using Edius 3.62 if that matters at all. I'm using external Seagate drives and checked and it's not the same drive as before. Thanks!!

    Well, I seem to have solved the problem. The audio clip I was using was an mp3 vbr clip. I converted to a wav file and the sync issue seems to have disappeared. Make any sense to anyone...?

      Yes... we've all been there.

      .mp3 requires extra CPU ticks... thus the lag.
      .wav is uncompressed.

        Is it just mp3's that have been encoded variable bit rate...? I've used mp3's many times in the past and have never had a problem. I think the audio track I had a problem with last time was a vbr encode as well - though can't remember for sure.

          VBR is much more likely to cause problems.
