why are you scrubbing the timeline in a lipsync project?

im doing animation in flash. i need the mouth openings of the characters accurately in sync with the given audio. I've been doing this type of job for quite sometime now,using MX, 8, CS2 and CS3, until CS6 gave me the problem metioned above. Doing this within the current software platform isn't my idea anyway.

during development, you can drag or click to position the playhead. then press enter (or your default play key) to hear undistorted audio.

and, for example, if you're debugging the audio/viz between frames 90 and 110, you can temporarily add a gotoAndPlay(90) at frame 110 to repeatedly see/hear what's occuring in that span.

Thanks for the advice kglad!Anyway, I'm still wondering why CS6 behaves that way. I don't remember having this kind of problem with the previous flash versions. I could scrub as slowly as a frame at a time and could still hear the audio hitting that point. I need to set the lipsync as accurate as possible, so this is a major concern to me, with respect to animating in flash. I know isn't really built for serious animating purposes, but since a trend had started years ago with Flash MX, it'll be a pain in the neck if the audio/scrubbing issue has got to do with the software itself. I'd rather do the animation elsewhere if that'll be the case.

i don't have flash mx anymore but i don't hear any difference between the way sync'd sounds play in cs3 vs cs6.

i can hear the audio play frame-by-frame when dragging but it is distorted.

You can't scrub a timeline and get anything but distorted audio, unless you can manage to scrub at exactly the FPS of the document. The premise is silly. Scrubbing gives you an idea of what's going on with audio but it makes no sense to allow you to scrub a timeline and let audio de-sync from your playhead. That would be extremely inaccurate.

i don't think scrubbing exactly at the fps would remove the distortion. and playing at just about any frame rate should play the sound distortion free.

Absolutely sarcasm, nobody can scrub perfect fps speed nor if you could would that be desirable. With Stream synced sounds playing with enter is as good as it gets. Even Premiere, where scrubbing is required, has no faux support.

I didn't mean to say that the frame-by-frame playback of the audio has to be flawless. What I'm trying to say is that flash used to play the portion of the sound with respect to the corresponding frame in the timeline. In my experience in CS6, the audio plays over on some frames only so there isn't a continuity of the sound playback when scrubbing. Could it be a conflict on bitrate vs frame rate?

Like what I said to kglad, I'm hoping for a continuous sound playback when I do timeline scrubbing. Right now, as I try to listen to the audio while dragging the pointer across a particular area in the timeline, some parts of the sound seemed to be "skipped" making the slow payback "choppy" in some sense. Honestly, I only use and know flash as an animating tool and I know very little of the expanse of its usage, that's why I'm asking for help from you guys.

I think this has got to do with some configurations in my OS and/ or CS6 itself. I know animators like me who use CS6 but don't have problems with audio while scrubbing. Just my theory though, hope you guys could bring about better ideas.

this is your best bet, i believe: and, for example, if you're debugging the audio/viz between frames 90 and 110, you can temporarily add a gotoAndPlay(90) at frame 110 to repeatedly see/hear what's occuring in that span.

Hi All,

Please upload some video having audio/video sync issues and also update the system configuration. You can use any of the free file sharing sites.
