Hi, I tried doing a search but couldn't find a thread that pointed to my issue. I'd like to keep my video formats but just convert the audio codecs. Is there a way to do this in handbrake? I can't find an alternate converter that simultaneously excludes the video in the conversion while also easily creating queues.
Specifically, I want to convert all my audio codecs to AC3 because that's the only kind my Roku will recognize as 5.1.
I'm using Handbrake 1.3.3. for MacOS 11.0.1.
Thanks!

Good god, everything about the mmpeg website and its application seems designed to scare away people just like me. I seem to be forced to choose between the hell of mmpeg's UI and other applications that offer next to zero granular control.
There are multiple graphic front ends to ffmpeg available. It has the advantage of being available for many platforms, and a lot of people write front ends to match their (personal or group) idea of the "perfect interface" for their operating system.
Subler likes the idea of converting codecs from ac3 to aac, but isn't a big fan of changing anything TO ac3.
I'm not familiar with a ffmpeg that has the UI I can use. Unless I read something incorrectly, I believe handbrake utilizes ffmpeg?
Avidemux has a fairly user-friendly UI and it has the option of video pass through while converting the audio, but I can't figure out how to create a basic queue, and uploading files frequently runs into errors.
To be clear, AAC does send sound to the surround speakers...badly. Against a film with AC3 there's just no comparison. In my Star Wars AC3, you can hear surrounding environmental sounds exactly as you'd expect. With AAC, it just extends the sound of the front speaker, albeit weakly.
Super Eight, 18 minutes in, one with AAC and the other AC3. With AAC, the train car explodes and nothing special happens with the sound. Like I said, it's just front speakers pushed to the rear a little. Coded to AC3 the explosion moves all around me as the camera moves.
When converting aac to ac3 do I need to increase the bit rate because aac works better at lower bit rates than ac3? Or would I just be adding file size? Another way to put the question is, if I already have a 256 bit rate aac, is my conversion to 256 bit rate ac3 a lateral or lesser move?
