I make music videos so I time clips very specifically to songs.
I need to match an original audio file exactly to a re-encode of the same file. I’ve clicked on show audio time units and have been nudging the clip as precisely as I can. But for some reason I can’t match it exactly.
Here’s a screenshot showing what I mean:
If I nudge the clip left or right, even when showing audio time units, it will go too far in either direction so the waveforms never match up. The difference is very small obviously but I can notice a difference in parts.
Is there any way to be more specific with the nudging here to make it fit exactly? Or another way to make it match the other file exactly?
Select both elements on your timeline, Right click / Synchronize / Choose audio.
Let us know.
Unfortunately that option was less accurate than manually doing it. Thanks for the advice though.
Is one of your audio tracks attached to a video track? you may have to unlink.
One of them was linked to a video file but isn't anymore
Is the timeline zoomed in as far as possible?
Yeah, the screenshot above is the audio at the maximum zoom. Basically, the trough that's next to the playhead at the top in that screenshot- I want to line that up with the trough in the audio at the bottom. But I'm already at maximum zoom and nudging it with alt-arrow keys moves it too far in either direction.

So how does it look and sound when you play back the audio?
Audio does not need to be 100% in sync with the video, it will look great anyway. Of course, a couple of frames off will be bad, but you are only a couple of time units off and no one can notice that when they see/hear the video.
I think there is an other way.
As Richard mentioned it, zoom at max or descent zoom amount at least.
Then use markers ( M ) to determine exactly the point where you want to synchronize on both tracks.
Select both tracks, Synchronize / Markers.
By the way, it seem to me to be an extrem kind of sync. Did the audio sync failed to synchronise correctly your two files ? It is pretty accurate since it synchronise audio track by analysing the wavefrom.
Let us know.
And nudging clips will always be based on your frame rate not the audio samples.
Thanks, I'll try that. Might be having some luck with just manual moving as well though so I'll see how I go. Yeah, the audio is a song with a lot of elements so I think that's why it may have failed.
I know it's less pricise, but try unchecking Audio time units it just to see if you get lucky and it happens to line up.
