Avid Media Composer Segment Overwrite


A commonly used function in Avid is the Red
Segment mode button, which is officially called the Life / Overwrite button. So, continuing on from the last lesson, check
out this part of the sequence. “We had a call from fire rescue that were
three men being extricated from a manhole and unconscious, and not breathing.” “Not sure of the cause right away.” Now, instead of having the doctor on screen
for almost 10 seconds, we can cut away to another clip of a worker being rescued. You can mark in points and out points for
an area in the sequence that you would like to replace. Now, since I only want to replace the video
portion of the Doctor without affecting the audio, turn off the audio track for the source
clip. I’ll find a clip of a worker being rescued
and I’ll load it into the source window. Place the blue position indicator at a point
where you would like to the clip to start. Okay, important, when dragging a clip to the
timeline, the Avid only obeys these track indicators in terms of what is added to the
sequence. And since I only want to replace the video
portion of the doctor, without affecting the audio, turn off the audio track for the source
clip. Even though these sequence track indicators
can be turned on or off, when you are dragging a clip to the timeline, they won’t affect
the end result. So now, when I drag the clip down from the
source window, you’ll notice it’s to long for the area that I’ve marked in the timeline. This is because, without having any in-out
points in the source window, the Avid measures the distance from the position indicator to
the end of the clip. This distance is shown here in the upper middle
portion of the composer window. The trick here is to hold down the command
key, and assuming you have enough content, the Avid will fit your clip into the marked
areas in the timeline. Okay, now that we are done with these in-out
points. You can clear them by pressing the G key. Okay, let’s watch through the sequence again. “being extricated from a manhole and unconscious,
and not breathing.” “Not sure of the cause right away” That plays much nicer than what we had before. Okay, now that we are done with these in – out
points, you can clear them by pressing the G key. Now, when it comes to moving clips around
in a timeline, the red segment arrow will either overwrite clips, and/or it will leave
a gap. So if I move my rescued worker off the right,
it will leave an empty space off to the left. Notice that it also overwrote a portion of
Interview 4. If you want to fill the gap with another clip
you’ll need to mark the area again. Instead of manually marking in and out points
for a segment area, you can press the T key. This will mark the area for you automatically,
based on the placement of your position indicator, and the sequence track that is turned on. Okay, some review, go find another clip and
load it into the source window and find the start point. Since we just want to edit the video content
of the clip, remember to turn off the source audio track. Then drag the clip into the space holding
down the command key. So let’s watch part of the sequence again. “being extricated from a manhole and unconscious,
and not breathing.” “Not sure of the cause right away, we came
to find out that there was possibly methane.” So now, our sequence is starting to come together. You can also use the red segment arrow for
deleting clip segments. So in this example, if the red segment arrow
is active, and a clip is selected, pressing the delete key will leave an empty space or
a gap. Then you will need to mark the space again
by pressing the T key to replace the gap. So, now I can drop in a different clip here
in place of the interview. However, this time, notice that how both source
tracks are turned on, which means the Avid will edit both video and audio content to
the timeline. Let’s watch through the final result. “We had a call from fire rescue, that were
three men being extricated from a manhole and all three of them were unconscious, and
not breathing” “Not sure of the cause right away, we came
to find out that there was possibly methane, 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 was approximately 32 minutes, that’s an excellent time, and it just shows
how good a specialized rescue team we got, and how good of a fire department we have. Okay, now you have the basics of using the
Red Segment arrow. And don’t forget, GeniusDV also offers classroom
