Music not sync’d with video
Hello again
I imported an audio file and added it to my timeline. While previewing, the audio is not sync’g correctly with the video. When rendered all is well. Is there some setting I need to tweak so the audio stays aligned with the video? This is crital for me as I will be editing some music videos and will need to cut on specific downbeats, breaks, drum rolls, etc
Thanks
If it doesn’t feel right, don’t do it. If it feels right, give it everything you’ve got.

Use the wave form to do the editing on. Much more accurate than ‘doing it by ear’.
You could prerender a specific area that you are working on and it should then be synced.Used to drive me crazy during capture when the audio and video did not appear synced. Helps if you have the preview set to lower quality setting. Decided I could live with it if the output was in synch and it always was.

Thanks. Not sure if I follow the “waveform” vs “by ear” part though. Can you break that down a little further for me? Also, I’m referring to custom audio, not the audio on the clip.

Not if you have any sense of musical timing 🙂

Agreed. I usually set it to Preview(Auto).
What you can do (and what I do a lot in similar situations) is to drop markers on the timeline (M key) wherever I want to do an edit.
Makes it much easier to find the right spot. -
If it’s “custom audio”, then I don’t understand what you mean by “not synced with the video”. The only thing you’d want to “line up” are the points where you insert transitions, and this can be done by placing markers on the timeline.
Just hit the M key to the beat of the music. Then go back and insert transitions at the marked points.
By “waveform”, we mean the picture of the audio that appears in any audio clip on the timeline…that blue squiggly thing. To see it more clearly, zoom in until you are at the frame level. The waveform trace will expand and become easier to “read”. The peaks often represent percussion beats in the music, allowing you to line the clip up visually.
By “audio/video sync” we mean the alignment of audio that accompanies the visual action of the clip…people speaking, clapping, etc. The audio that your camcorder captures will always be in sync with the video (unless you deliberately unlock the audio from the video in Vegas, and then move the clips out of alignment). But if you are shooting with multiple cameras, or have a digital audio recorder, you’ll often want to sync up audio from one source with video from another source. Here’s where the waveform display in the audio clips can help quite a bit.

What I mean is that I need to be able to line up an, e.g., snare drum hit with, e.g., frame number 116. I need to sync the beat of my song with my video cuts. So I line them up visually, but when played back, they are not playing together as they should. I must be able to preview with the correct audio timing.
>Just hit the M key to the beat of the music. Then go back and insert transitions at the marked points.
This sounds good in theory, but again, when played back in Vegas, the music is not lined up with transitions.
>By “waveform”, we mean the picture of the audio that appears in any audio clip on the timeline…that blue squiggly thing…
Right,that is what I’m doing. But again, Vegas will not preview them correctly when played back. There is latency in either the audio or the video.

Understood. The source audio and video sync is not in question as I have deleted all the source audio and replaced it with my own audio clips.
If it doesn’t feel right, don’t do it. If it feels right, give it everything you’ve got.

I will definitely use markers now, but I’d sure like to hear what the rendered output is going to sound like

Many times the preview window will lag a bit. If you really want to see how the audio and video fit in a transition, create a region over the transition and do a ram render of the region and then play it. It will show you just what the output will look like.

Okay, here’s one possible reason things are off…
Are you previewing the video on an NTSC television monitor, via a Firewire connection to your DV camcorder or deck, but listening to the audio through speakers hooked up to your computer? This will produce a noticeable lag in the video.
Either monitor the video on your computer monitor, in the Vegas preview window, or use speakers connected to your television monitor. This will keep the audio and video in sync.
