How to Reduce After Effects Render File Size

"I'm using Adobe After Effects CC 2017 and I want to reduce the render file size. However, I Googled all day and I cannot find any for CC 2017. All of them says that change the format to H.264 but we cannot do that in CC 2017. Please help me."


To render H.264 it's actually very easy. You can do following steps I show you.

  1. From your Project window, select the sequence you wish to render.
  2. Right click->Export Media (or File->Export Media)
  3. In the Video tab, select H.264 for format

Then, in the basic video settings below, you can change to smaller-than-original resolution, low bit rates, etc.

If you are trying to export a Quicktime file that uses H.264, that's much more challenging. When you select Quicktime, After Effects gives you a useless menu of Presets that were relevant for about six months during the early 1990s. Ignore all of them, as they are stupid. Instead, look down to where there's a Video Codec selector. Click on that and you'll see tons of options, including H.264.


I suggest that you should output a Quicktime file that uses H.265. That's great since HEVC is, as its name implies, a high-efficiency way of recording video. That means files can be smaller than those encoded with the older H.264. However, I believe that you have found that no matter which format you select, the render file size is still large. It not easy for you to upload the file to Youtube or other video sharing website. So here comes the third method - reduce vdieo size with third program. Can't wait to know which one I am using?

Step 3: This part is important. After you select desired format, click "Settings" and enter "Profile Settings" window, you can adjust video parameters here. The video size is based more on bit rate than pix, lower bit rate to get smaller video size. I always select medium quality or low quality to reduce After Effects render file size.
