"enable Show Deprecated Formats." does not appear in output setting. How can i fix this? I'm trying to render out in H.264 but I don't even have the option to turn on "enable Show Deprecated Formats" Please help
That feature was removed in recent versions of AE.
For what it's worth, AE never did a good job at making H.264's
I will grant that it was pretty handy for a quick preview, but it doesn't take much longer to render an intermediate file to a watch folder and then have the Adobe Media Encoder automatically knock out a quick MP4 from that (in fact, that is sometimes quicker than render an H.264 from AE was).
