Dolby Headphone Encoding

Not sure how much is known in the open source community about the inner-workings of Dolby Headphone, but I think it would be a nice option for those who encode movies for playback on their iPod/portable devices but still want some of the surround effect. I had the privilege of demoing the technology...

SUMMARY For best results (but not necessarily 100%): 1. Use the command-line interface 2. Make sure your sample rate is the same as your input file (almost always 48kHz) 3. Do not go above 160kbps for audio bitrate if encoding to stereo (unnecessary anyways as the encoder will not do above that any...

I agree with jbrjake, I don't think you'll need to go above 3000 for DVD-resolution sources to receive an excellent output file.

Also, I believe it is a known issue with QT/iTunes accepting files over 4GB in size.

I'm not 100% sure, but I don't see why they wouldn't work with Front Row. iTunes/QuickTime have native support for them. EDIT: I believe those AppleScripts will only work on .mov containers as well.

I believe jbrjake mentioned in the IRC channel that if you encode @ 48kHz, it allows the audio to be encoded at a slightly higher level.

I haven't been able to playback the file entirely yet (at work), but the audio did not drop out anywhere in the encoding so I'm pretty hopeful it turned out alright. This was the first title (X-Files Season 1 NTSC, Disc 4, Title 3) that has exhibited this problem since switching to CLI mode.

MetaHoot will let you add chapters manually, or by rescanning the DVD. However, it only works with .mov files (not .mp4).

What about the Khz?
I'd match whatever the source is; typically 48kHz I believe.

I don't really think this is that big of a limitation when a stereo AC3 file is stored at 192kbps (or 96kbps per channel) and AAC is a newer format, created by Dolby Laboratories, that is built with efficiency in mind. AC3 is still compressed at various bitrates (384 or 448 for DVDs if I remember co...

Doing some quick research this morning, this may not be as big of a deal as I thought. Aren't Dolby Digital stereo soundtracks limited to 192kbps? And AAC is supposed to be a more efficient codec, so 152kbps should sound equivalent.

It's essentially done for the CLI, and this code shou...

That is what I did last night when testing in the IRC channel, but when I tried to load the "fixed" VOB, handbrake reported a duration of 00:00:00 and wouldnt encode, which I think is related to the second issue mentioned earlier.

I don't believe MPEG in itself is a lossless codec. Anyways, encoding at 100% will give you a very large file, but of excellent quality. If you are wanting to playback on an AppleTV, I would not reccomend this as the bitrate and sizes would probably be over the unit's limits.

I could be wrong about that though. Also, I have been able to use other programs (MPEG Streamclip) to encode the VOBs to MPEG4 with...
