Remove Alpha channel option when exporting h.264

If h.264 doesn't support alpha channels, why is it an option? I just wasted a bunch of time exporting all of my files in the wrong format because I figured it has to work if it's an option. Even RGB+Alpha is greyed out. So why not do it for the other alpha channel option?

Hi @austind69658590,

The Alpha option for H.264 export might be more accurately named "Alpha Only" because it exports the alpha channel of the composition as a black-and-white matte. This is important for many workflows since H.264 itself doesn't support an alpha channel.

 

Thanks for making this post,
