After Effects Exporting HD Video for YouTube

After Effects Exporting HD Video for YouTube
The fun part of creating videos in After Effects is uploading them to YouTube and other social networking sites. In this tutorial, we will export our finished book app trailer for uploading to YouTube.

We will use the most common HD resolution settings supported by these sites which are 1280 x 720 (16:9 aspect ratio). You probably have used a frame rate of 30 to shoot your video. If you have use an even higher frame rate for shooting your video, you should still use the 30 FPS frame rate when exporting your finished project.

As for the most common audio settings, you will want to use the AAC-LC Advanced Audio Codec and a data rate of 320 kbps for your audio.

Open After EffectsR CS6

    First we need to verify that we have the beet settings for our composition.

  1. Click Composition - Composition Settings.

  2. In the Composition Settings dialog box, verify the following settings.

    Preset: HDV/HDTV 720 29.97
    Width: 1280
    Height: 720
    Pixel Aspect Ratio: Square Pixels
    Frame Rate: 29.97 (or same as the frame rate used to shot the video)

    Once we have these settings for our comp, we can export the video for viewing.

  3. Click Composition - Add to Render Queue.

    You will see a few links in the Render Queue panel.

  4. Click the Output Module: Lossless link to open the Output Module Settings dialog box.

  5. On the Main Options tab, set the Format to H.264. This is the suggested format for YouTube and Vimeo.

  6. At the bottom of the dialog box, put a check in the box next to Audio Output. If you forget to do this, your video will export without any sound.

  7. Set the Audio Output to 44.1 kHz

  8. Click the Format Options button to open the H.264 Options dialog box and set the following values.
