AC3 advice

Post by rsvictor1976 » Tue Jan 08, 2019 2:23 am

I have some movies that are in DTS-HD with only 2 channels that I want to backup on to a Plex server. I'm playing primarily on AppleTV 4k with 5.1 surround system, iPad Pro, and Iphone X.

For sources with 5.1 channel audio, I've been using AC3 passthrough or AC3 640 bitrate Surrounnd. But I'm not sure what to use for source with only 2 channel audio.

1. For sources with 2 channels, is it better to encode in AAC or AC3?

2. I noticed if I choose AC3, it gives me the option to mixdown to stereo or surround. Should I keep it to stereo or set it to surround?

If the source is only two channels, you're only going to get stereo out no matter what the settings.
