Avid Media Composer Ripple Trim Function

Let’s focus on how to use the ripple-trim
smart tool function. To demonstrate ripple trim, let’s take a
look where we left off from the last lesson. “inside they were doing work, and I believe
it was a sewer hole.” “From the time the run came in, until we
got the victims out…” You’ll notice that this shot of the ambulance
runs a little too long. Instead of having to re-edit the clip, you
can use the ripple trim function to shorten the segment. Off to the left side of the timeline, you
will see the smart tools palette. Activate the yellow ripple-trim function. Again, if you are new to Avid, I recommend
that you only work with one smart tool at a time. So for now, make sure all these other smart
tools are turned off. Also, to help me demonstrate ripple trim,
turn on these clip durations within your clip segments. To do this, navigate to the timeline fast
menu, and choose clip text – clip durations. So now, move your mouse cursor towards the
end of the clip segment and wait for your cursor to turn into the yellow ripple trim
icon. Then click on the edge of the clip. Make sure you see a yellow line at the end
of your clip segment. Note, If you see two pink lines, you’ve
changed into a different trim mode that I will cover later, so make sure the line is
yellow. Now, you’ll notice that the controls within
the composer window have changed. This is because by clicking on the edge of
the clip with the ripple trim icon, it will take you into trim code. When you are in trim mode, you are looking
at last frame of the outgoing segment, versus the first frame on the incoming clip segment. So lets shorten this clip of the rescued worker
going into the ambulance. Notice the duration of this segment is 6 seconds
and 23 frames long. As you drag the yellow trim handles to the
left you will be shortening the clip segment. When you let go of the mouse button, the sequence
will be shorter by the amount of time that you’ve trimmed away. Notice the new duration of the clip segment
is now 3 seconds and 27 frames. Now, if you change your mind, as long as you
still have the yellow trim handles, you can always add additional content by dragging
the yellow handles the opposite way. Also, if you take a look at your keyboard,
you can use these keys to perform the trim function without having to drag the mouse. The M key and forward slash key trim 10 frames
at a time, and the less than and greater than keys trim 1 frame at a time. Now, when you are trimming clips with using
the ripple trim tool, you can also trim from the front of a clip segment. So in this example, I’ll trim the head of
the clip segment so the paramedics are closer to the ambulance. Okay, after you’ve completed your trim,
click in this grey time-code bar area to return to normal editing mode. Awesome, so let’s watch part of the sequence
again. “They were doing work, and I believe it
was a sewer hole.” “From the time the run came in…” Ahhh, that’s much better by trimming that
shot down a bit. Now, an important side note. When trimming clip a segment that has sound
attached to it, it’s important that you trim the video and audio elements equally. The good news is, by default the Avid will
automatically select the audio and video elements for you, unless to your turn off this link
selection icon. So be careful, because if the link selection
icon is turned off, it’s possible to force your video and audio content out of sync. And if that happens, as indicated by these
white frame indicators, you will want to undo your previous action. Okay, now you have the basic fundamentals
of using the ripple trim function. And don’t forget, GeniusDV also offers classroom
and flat rate onsite Avid Media Composer training.
