If you do a lot of conversion from video DVDs or VIDEO_TS folders to the other formats there is a time-saving advantage to Popcorn and I presume Crunch. Toast 8 and 7 require the MPEG video to first be extracted (copied) from the DVD or VIDEO_TS using the Media Browser before the video can be exported to other formats. Popcorn and Crunch do the exporting directly from the non-encrypted DVD or VIDEO_TS.

Hello, could you go in more details on how Crunch handles AC3 and DTS audio conversion to Apple TV AAC standard.

 

Have have been using tools like Handbrake and Visualhub but both lack LFE channel support when they convert to Dolby Pro Logic II rendering a 5.0 surround sound only.

 

I'm looking for a tool that can maintain the sound quality of the Video_TS files i'm trying to convert. In the case of DTS keep it as is, as the Apple TV can passthrough DTS encoding.

 

Thx

Crunch won't help you there. It doesn't accept DTS tracks. Even when you have a 5.1 AC-3 track it will convert this to 2.0 AAC-LC(Music) with your choice of several bit rates (default at 128 kbps).

 

Where did you see that AppleTV passes through DTS encoding? The only specs I've read are the ones on Apple's product description page and it only mentions AAC-LC audio. I haven't been interested in AppleTV because it seems very limited in what it can play. Maybe I'm just not seeing the whole picture.

If you visit this site the guy have conducted a toughrough exaplanation of what it can do and not do.

 

As for the DTS there is a DTS test file it is audio only but it is only to show that the Apple TV can pass DTS signal via Optical link (like i'm setup) and if your Audio receiver can decode DTS music will play. You can actually download a DTS sample file from here

 

I'm just about to do a test with a DVD that i will try to encode first for the video, extract the DTS track and merge the two together with Quicktime Pro.... will let you know how i'm successfull doing that.
