I am trying to export a video through AE CC 2017 and I need it to be H.264 , but I am unable to find it , and the Show Deprecated Formats is not there in the output preferences , how do I get this done ?
Thank you !
You render the comp through Adobe Media Encoder as it is supposed to.
As Mylenium says, the option to show them is gone because the ability for AE to render to them is gone.
You either render an intermediate codec and then use AME to make your final deliverable (the way I've done it for years - even before they deprecated those files) or you can render via the Adobe Media Encoder.
