[AAC] AAC (avcodec), AAC (FDK) or HE-AAC (FDK)

Feb 2, 2015 at 2:08 AM

I'm encoding a BRRip of 3GB to 700MB, I'm using VidCoder, I need to encode the Audio using AAC, in the settings I go to Audio and I don't know what to choose, AAC (avcodec), AAC (FDK) or HE-AAC (FDK).

I searched all over the internet for help, could not find article that actually help me understand what I need.

I know that I need the file to be compatible with mobile devices as well and not only on PC, I want my file to have the maximum compatibility, and I need to use AAC, so which one of the three to choose.

Can you help me?

And maybe on the way, you can explain in a basic language what each one of the three means and particularly what it is used for.

Thanks in advance.

AAC (avcodec) will be compatible with mobile and is a good default.

So, AAC (FDK) will not be compatible with mobile devices?

It's probably still compatible, I think most of the differences are just encoding quality and options.
