Trim with Avid Media Composer Slip Mode

The slip mode is a function within the trim mode in Avid. This power editing tool can be used to trim and edit clips within the timeline. Slip in particular is useful for when clips have been spliced together and the spiced area does not quite work properly. With slip, it is possible to change the moment until the new clip blends seamlessly in with the old.

Step 1: Enter Slip

The slip mode can be entered when in timeline view, as it is not necessary to be in the source monitor. To enter this mode, select the clip in the timeline using the lasso. Slip mode can also be entered in the trim mode, and then right click the segment that needs to be trimmed. Then, select the slip trim options.

Step 2: Slip Frames

Once the slip mode is entered, then the trim rollers will appear at the cut points within the clip. Four different screens will pop up for a single clip. Two of the screens, the inner ones, are the tail and head frames of the clip. Then, there will be the head and tail frames for the master shot or the footage that the clip was inserted into.

Step 3: Change Frames

Slip mode is used to alter the head and tail frames of the clip so that it flows seamlessly. Drag the roller to change the head and tail frame. As the slip is changed, the frames will change. Check how the seams work and keep changing the rollers until the transition between the clips is seamless and works to your satisfaction.

Step 4: Timing Changes

Basically, how this slip works is that when the head frame is changed or frames are added at this point, the same amount of frames are subtracted or added onto the tail side. The slip mode keeps the same number of frames within the clip it simply changes where the timing of the clip enters the master shot. The timing can change but the actual duration of the clip does not change.

Step 5: Multiple Clips

It is possible to use slip mode on more than one clip. So, it is possible to trim several clips including the audio track for that clip. The gradient bars on each clip will show which clips are selected for trimming. The ends of the clips will be yellow so you can see what is selected.

Step 6: Key Shortcuts

Instead of using the mouse, it is possible to use the keys to trim frames. The keys that can be used to slip the different clips are >>, >, < and <<. Using the keyboard or the mouse is completely up to the user's preferences. There are also key shortcuts to enter the slip mode. Put the cursor where slipping will be used. Then, right click the segment or hit shift and the control button. The timeline menu is revealed and the slip trim can be used.

Step 7: Exit Slip

To get out of the slip mode, simply select the button for trim mode or select the TC1 track. Now you can do other editing within the clip.
