In Aftereffects, click on the composition in the project window, then under the composition menu, choose composition settings.

Your Settings for everything except for the duration of the composition must match the settings below.

If you are working with 24 frames per second - you should replace 29.97 with 23.976. In most of my classes - we use 23.976 because it matches with the fps of the cameras that we shoot with.

In Aftereffects, open the Render Que from the Window Menu. Drag the composition from your project window to the Render queue.

The render queue is a list of compositions that will render when you hit the render button.

1. Set the "Render Settings" to ‘Best’ using the drop-down menu.
    Click on the name of the movie, to check the render location.
2. Click on the word "lossless"

Adjust all of the settings to match the picture.


1. Change the format to Quicktime movie.
2. Click on the Format Options
      set the codec to "Avid DNxHD Codec"
     set the quality to ( 100%).
      Click on Codec Settings and Match the popup below
     IF you don't see this option you need to quit and install the AVID CODECs
3. Check the Audio Output box only if you have audio.
      if you have audio set sample rate to 48000 and 16 bit.
4. Click OK

Save your Project. Then click RENDER.
