41 HDV and Multi-Camera Editing, Part II


#41 HDV and Multi-Camera Editing, Part II

This tip leverages two features of Premiere Pro. First is the ability to jump from the edit sequence to the same point in the synch sequence by pressing Shift+T. With this keystroke combination, you can jump from any nested sequence to the same point in the original sequence.

Can You Mix HDV and DV in the Same Multi-Camera project?

Absolutely. If your target is SD, you'll have to downconvert the HDV video down to about 46% to fit perfectly in the 16:9 SD window. If your target is HDV, consider upconverting your DV video to HDV in After Effects, which produces better quality than Premiere Pro during this process.


Second is the ability to set keyframes to "Hold," so they don't change until manually adjusted later in the project. As you may know, the default behavior for keyframes is to interpolate their values from one position to the next (see #60 for a description of keyframe operation).

Essentially, these two features allow you to pan and zoom in the synch sequence and have the effects flow through to the edit sequence. Here's how it works.

1.

Create your synch and edit sequences and select your camera angles as normal.

2.

In the synch sequence, click the Toggle animation clock to the left of the Position and Scale properties to add keyframes to the start of each HDV clip you intend to pan and zoom.

3.

Right-click the Position keyframe and choose Temporal Interpolation > Hold from the menu (Figure 41a).



Figure 41a. In essence, if this keyframe was a dog, selecting Hold is like telling it to "stay." In other words, don't move until the editor manually adjusts the setting.


Real Panning and Zooming

The procedures described in this tip let you change the static position of your HDV video from keyframe to keyframe. You could produce actual pan-and-zoom motion within the clips by choosing the linear interpolation method between sets of key frames, which is in the same menus described in steps 3 and 4. Just remember to reset your last key frame values to the desired position, and the interpolation technique to Hold to reset all subsequent uses of that clip to the desired position in the edit sequence.


4.

Right-click the Scale keyframe and choose Hold from the pop-up menu that appears.

5.

In the edit sequence, navigate to the first target frame for a pan-and-zoom effect.

6.

Press Shift+T. Premiere Pro takes you to that frame in the synch sequence.

7.

Click the Add/Remove Keyframe button to add the necessary keyframes in the Position and Scale properties at that location. Note the current values for those properties because you'll restore them in step 12 (Figure 41b).

Figure 41b. Use subsequent keyframes to create the desired pan and/or zoom effect.


8.

Use the Position and/or Scale properties to pan and zoom around the clip as desired.

Note

Setting these keyframes adjusts the position and scale of the clips from that point forward, affecting all subsequent uses of that clip in the edit sequence. You'll reverse that in the next few steps.

9.

In the edit sequence, navigate to the last target frame for the pan-and-zoom effect.

10.

Press Shift+T. Premiere Pro takes you to that frame in the synch sequence.

11.

Click the Add/Remove Keyframe button to add the necessary keyframes in the Position and Scale properties at that location.

12.

Adjust the values back to the settings before the adjustments made in step 7.

Note

Just in case you forgot to write them down, the default settings for Position on an SD timeline are 360x240. Most of the time, to make 1080i video fit in a 16:9 DV SD frame, you'll scale it to 46% of the original.
