Rendering and Exporting

Last updated 11/30/2015

• Changes in frame rate may require the use of frame blending to smooth out the interpolated frames. For longer

footage items, the use of frame blending can result in very long render times.

1 Import the footage you’re converting into a composition using the preset of the format you’re converting to.

Example: if you’re converting NTSC to PAL, add your NTSC footage item to a composition with the appropriate

PAL composition settings preset.

2 Select the layer with the footage to be converted and choose Layer > Transform > Fit To Comp Width (or Fit To

Comp Height).

Note: For converting between two formats with the same frame aspect ratio, either of these two Fit commands does the

same thing; if the frame aspect ratios differ (for example, going from 4:3 to 16:9), fitting to width or height chooses

between cropping or letterboxing the resulting image.

3 Do one of the following:

• If your footage has no scene cuts, choose Layer > Frame Blending > Pixel Motion. Pixel Motion provides the best

results for interpolation of frames, but may require long rendering times.

• If your footage has scene cuts, or if you want to sacrifice quality for shorter rendering times, choose Layer >

Frame Blending > Frame Mix.

4 Choose Composition > Add To Render Queue.

5 In the Render Queue panel, next to Render Settings, choose the appropriate preset from the menu. For example, if

you’re converting to DV footage, select DV Settings from the menu.

6 In the Render Queue panel, next to Output Module, choose the appropriate output module preset from the menu,

or choose Custom to enter custom settings. For example, if you’re converting to DV PAL, choose the D1/DV-PAL

output module preset with the audio sampling rate that you require.

7 Click the name of the output module preset that you chose in step 6 to select additional Format Options.

8 Specify a name and destination for the output file using the controls to the right of the Output To heading in the

Render Queue panel. (See

Specify filenames and locations for rendered output.)

9 Click the Render button to render your movie.

Convert DV footage from PAL to NTSC using pulldown

Because After Effects can easily convert film (24 fps) to video (29.97 fps) using 3:2 pulldown, you can perform a clean

PAL-to-NTSC transfer by setting up 25-fps PAL video to act like 24-fps film. This lets you apply 3:2 pulldown to the

footage when converting to 29.97 fps. This technique works especially well for progressive (noninterlaced) PAL video.

1 Create a new composition with the DV NTSC or DV NTSC Widescreen preset.

2 Import your DV PAL footage into the new composition.

3 Select the layer with the DV PAL footage, and choose Layer > Transform > Fit To Comp Width (or Fit To Comp

Height).

4 Do one of the following:

• To preserve audio synchronization but slightly lower the pitch, choose Layer > Time > Time Stretch, and then

enter 95.904 in the Stretch Factor box.

• To preserve audio pitch but not synchronization, or for clips without audio, right-click (Windows) or Control-

click (Mac OS) the footage item in the Project panel, select Interpret Footage > Main, select Conform To Frame

Rate, and then enter 23.976 in the Conform To Frame Rate box.

5 Choose Composition > Add To Render Queue.
