#Subler hangs opening m4v mac os#
MetaX and/or iDentify Subler remux Quicktime, which is now built into Mac OS X. Tools you’ll need: Handbrake or whatever tool you’re using for ripping your legally obtained DVDs. This is not a point-and-click process (yet :P) and requires the use of multiple tools and the shell. Note: This tutorial assumes some level of technical proficiency. So here, in abbreviated form, is the process for merging m4v files together and preserving chapter markers. Unfortunately, this is not an easy problem to solve and even involved me writing a small script that could merge chapter files together because every single method I could find would eliminate chapter markers. Well, digital media imposes no such restrictions on us, so why have two separate movies listed on the AppleTV? So after much trial and error, I finally discovered a way to get everything play nicely together. Really, they’re one movie, but are distributed as two separate movies because of the restrictions of physical media. This is usually movies like the Lord of the Rings Extended Edition or The Ten Commandments. Well, one of the problems I’ve run into a couple of times is longer movies that are distributed on two discs. But for audio conversion, it not reliable for me, yet.As I’ve mentioned a couple of times before, one of my projects right now is ripping all the DVDs I own so that I can watch them on my AppleTV (or any AppleTV in the house). While the above process gives me what I want, it would of course be more convenient to just use one program like Handbrake to achieve everything. I also use another program to produce an additional AC3 track from DTS, which I also just mux with Subler. aac track together with Subler, adding subtitles, chapters, artwork. Then I mux the videostream (from Handbrake) and the. caf file, I open it up in Audacity, and apply desired dynamic compression, and amplification of the track to reach a good volume. caf file, I downmix it with Sox, using a well working stereo downmix matrix, that is normalized.Īfter having the downmixed. caf file (which supports larger 2GB file size). So what I do instead, is to use ffmpeg to extract the AC3/DTS track from my MKV, and let it uncompress to a. It's just that they lack precision and quality I need when it comes to audio conversion. With that said, both programs are of course excellent. I simply cannot use software that don't produce reliable results, because it's quite tedious having to doublecheck the results after each conversion. No real documentation, too crude settings, and several failures of channel mappings when going from a 5.1 track to 2 channel track. Gain function doesn't seem to take into account clipping, and there is no normalization function. However, both options are too crude and are a gamble, today. You can control this via the gain function, and also apply some dynamic compression. Also, the volume of the tracks are usually too low. In either way, I can't take the risk of having Handbrake produce severely clipped stereo tracks that sound horrible to listen to. It seemed like the downmix matrix was not normalized, or something else was bad. I had a look at a downmixed 2 channel DPLII track, and it had severe clipping. However, the downmix matrices are not documented anywhere.

You can chose normal stereo, or Dolby Pro Logic II, etc. And you have very crude audio settings to chose from.įor example, when having a 5.1 AC3/DTS track, you can let Handbrake downmix it to a stereo track. I discovered that both Subler and Handbrake aren't doing a great job when it comes to audio conversion.

Transcoding a full BD MKV takes 2-4 hours
I have a 6-core MacPro I can remux a BD MKV in 10-15 minutes. Transcoding is the conversion of streams to a different codec. Muxing is the process of assembling streams inside of a container.

MP4 is more specific, and Apple's support of MP4/m4v is far more restrictive, especially on ATV. MKV is universal - there are no practical limits on what codecs can be encapsulated. Not all of the remuxing tools can do that.īoth MP4 (aka m4v) and MKV are containers that can contain video and audio streams with various codecs.
DTS material, whether DTSMA-HD or lossy DTS core must be transcoded to AC3 for ATV playback. It also helps that much of the blu-ray video content is already in H.264 format and is therefore compatible.īe aware that ATV (whatever the version) only plays AC3 (Dolby Digital) or stereo (AAC).
When the ATV was 720, most everything had to be transcoded, so the talk was mostly about Handbrake and such.
#Subler hangs opening m4v 1080p#
The reason ATV3 has people talking about muxing using things like Subler and MP4Tools is due to it being 1080p and there being a lot of blu-ray rips in MKV containers in people's libraries.
