Timeline time resolution

I want to slide a clip in a track to line up rhythmically with a another track. Just need to nudge it less than 1 second from where it is. Be there a way to change the measure to frames or milliseconds?

As far as I know, no.
That would also be highly unusual in the film industry.

But what is available is the ‘SMPTE time code’ for the film and music industry for syncing. But this is not implemented in SC.

What you would have to do in your case is to mathen your framerate into milliseconds. But then these are whole jumps depending on your framerate.
E.g. 1 frame at 30 Fps would be 500 ms, - 1 frame at 60 Fps would be 250 ms etc.

I was struggling with precise positioning of clips.

With snapping on, dragging a clip or its ends will snap to the nearest change (split or end of clip) on any track.
I found I could position the play head line to the nearest frame to where I wanted and dragging a clip would snap to that.

With music sync, you could position the play head based on the audio waveform, assuming you have high enough frames per second set.

Here’s a tip for precise positioning of a clip.

  1. Position the play head the precise position you want the clip to begin.
  2. Select the clip, wherever it is. Don’t drag it anywhere. Just select it, press C, then DELETE, then B.

Ta-da, the clip will be positioned at the playhead.
Note - if it’s a long clip, the playhead will move to the end of the clip and maybe force the timeline to move along. If you need to get back to the beginning of the clip, just double-click the clip.

Let’s say there is audio on A1 and A2, and they need to be synchronized somewhere in the middle of the clips to provide buffer at the ends for fade-in/out. (Or perhaps the ends can’t be synchronized because the waveforms are too small due to music that’s fading in.)

The way I do it is to call A1 the master and set the playhead at the beginning of a spike in the waveform. The timeline must be significantly zoomed in to see individual frames. Then, turn off the Snap (magnet) icon. Move the clip on A2 until the correlated spike lines up with the playhead (which was synced to the spike on A1). Done.

What I usually do is leave Snap turned on because it’s useful. Then, when I click and drag to move A2, I hold down Alt on the keyboard to temporarily disable Snap. This lets me move a clip by an exact number of frames.

It is already in video frame units, and you can position to the frame. See about time values at the bottom of the Keyboard Shortcut Reference page. If you have trouble position, you can turn off snapping and zoom in. There is a tooltip that appears when moving or trimming that shows the amount you move in timecode.
