Blu-Ray to Apple TV

what?? why?? no it isnt..

Seems, I may be wrong, but I haven't tested it myself. Release Take 2 apparently allows 64 bit containers so if you handbrake the file correctly, apparently it will work now.
 
The apple tv has *never* had a 4GB limit. Prior to Take 2 Streaming a 64 bit mp4 was a bit sketchy. But 64 bit mp4's have always been playable on the atv.

64 bit mp4's are required as 32 bit mp4's cannot be over 4GB. Has nothing to do with the atv. its an mp4 limit.
 
I stand corrected, but I know the last time I tried it pre-Take 2 it did not work for me.
 
I miss the Take 1 Interface. Take II is WAY too heavy focused on iTunes. iTunes should have it's own tab and not seep into everything you do on the Apple TV.

I the fired up the latest svn of Handbrake and, using Cave Mans recommended settings for the apple tv, I processed both the MKV's. The Italian Job came out at approx. 3GB and the quality is excellent when viewed on the Mac or via the apple TV. However, Ghostbuster came out at almost 6GB and won't sync with the apple tv. If both the MKV's were approx. the same size, wouldn't you expect the output of Handbrake to be approx. the same size and not double? Also, anyone know why Ghostbuster won't sync with the apple tv???

I'm guessing it's because the bitrate for Ghostbusters is past the Apple TV limit. Fire up the movie in Quicktime, show the Movie Inspector and tell us what the bitrate is.
Are you sure you are using CaveMan's setting because i believe he fixes his bitrate in HandBrake - if you did that then i would expect the 2 movies to come out about the same. Sounds like you used CRF for encoding if one movie is double the size of the other.
 
^^I am pretty sure Cave Man uses CRF as in the guide he says leave the setting at Constant Quality of 60.78% unless there are different settings.

Use MediaInfo Mac to find out bitrates :)
 
So it does, that'll teach me to re-read his guide :D I'm sure it used to be fixed, but CRF is definatly the way to go.
I'm still guessing at bitrate though.
Cheers
 
lol

On bitrate, can't the TV only handle up to 5.5 Mbps? (or have I misread somewhere) that may be what is wrong with aidym's encode :)
 
very true, in fact with earlier vbv testing it can handle burst as high as 13,000 kbps very well and that was with cabac, with cavlc I would suspect it could handle considerably higher as it's easier to decode. It is documented in some apple notes somewhere and proved to be true in testing.

I just found that its actually 7500kbps. I've got some Firefly episodes in 720p that fluctuate around 7000-9000kbps and only the ones under 7500 will sync.

No, Apple's specs have always been notoriously conservative. It is easier to post specs well under what is capable, then post things that are too close and then run into problems.

I was being sarcastic, hence the :p :rolleyes:
 
Hi all, sorry for the late reply and thanks for your help.

The inspector in QuickTime gives me a Data Rate of 7208.98 kbit/s

In MediaInfo I get a Total Stream BitRate of 7854 kbps

Sorry for my ignorance, but if it is the BitRate thats the problem, how do I get it to 7500 or below?

Are you certain that you set the frame rate to 24fps? Every time I've had a failure to sync (because of high bit rate) using the CQ encoding it was because I forgot to set 24 fps.

I've never had to set my FPS when encoding Bluray/HD-DVD sources... I always use "Same as Source" and haven't had a problem yet.

Yep, I have tried both 'same as source' & 24, and they both produce the same bitrate.
 
Why would anyone want to rencode blu-ray to ATV

1) It takes forever.
2) Quality is degraded.

Just get one of these wdtv units.

Sure it has no ethernet port.

But It is easily hackable to use a USB ethernet.

And it plays all these ripped formats mkv, m2ts, etc. at 1080p. No loss in video quality.
