Part 2: How to Export After Effects as H.264 Video

HEVC (also known as H.265) codec footage in a QuickTime (.MOV) container: 3GPP (3GP, 3G2, AMC) Import only: Adobe Flash Player (SWF) Import only: Note: SWF files are imported with an alpha.

What should be the best alternative if you cannot export After Effects project to MP4 directly? Whether you render to QuickTime format and use H.264 for the codec, or render it normally in AVI format, you can convert the video files to MP4 videos.

I don´t know about CC versions of Premiere and After Effects. But I can tell you how animation codec works. It´s a codec that makes a quicktime file with no compression, so the file size you´re getting with this codec is big in comparison with h264 or png or jpg codecs.
I tried rendering them in After Effects CC 2018 to get better results, but the H.264 had disappeared. Which codec should I use? For some reason the default setting is 'animation.' I'm not sure what settings my QuickTime uses; I've been unable to find them. QuickTime is not listed in my system preferences.

Step 1 When you have made the creation, you can head to the Composition menu and choose the Add to Render Queue option to export the projects of Adobe Effects to H.264 videos.

Step 2 Click the blue text to open the Output Module option. After that, you can change the Format as QuickTime. Open the Format Options menu list. Under the Video tab, change the Video Codec to H.264 and set Quality to 100.

Step 3 Now you can name the project file and choose the destination folder before clicking the Save button. Click the Render button to render After Effects project to H.264 movies to QuickTime instead of MP4.

Note: If you have already installed the Adobe Media Encoder, you can choose the same H.264 files to MP4 files. Actually, both MOV and MP4 enables you to playback the After Effects videos on your iPhone.
