How to make CC on a win OS?

You can use MP4Box to import a ttxt file into your mp4 file:

MP4Box -add [ttxtfilepath]:lang=[yourlangcode] [path_to_a_valid_mp4_file]

You can convert a .srt file to .ttxt using:

MP4Box -ttxt [srtfilepath])

Afterwards you need to edit a your .mp4v (on Mac use Dumpster, I don't know about a Windows equivalant). Set moov..mdia.hdl.subType to sbtl. Now you have your subtitles on your Apple TV. However the top is cut off and just one line is displayed.

- The subtitle is located top left instead of bottom center. How to change that?

You can alter the position of the subtitles in Quicktime. Select the track in Quicktime and then go to visual settings. There you can edit the offset of the subtitles. Though after saving the movie in Quicktime again you'll get a mov instead m4v file. (I still don't quite get the difference between those two)

There is a second way however. Edit it directly in Dumpster. The offset is stored in moov > trak > tkhd > matrix. In my example I set an offset of 158x500 for my movie. This resulted in the following values in the last line of the matrix: 0.0158, 0.0500, 0.01. You get the picture

Actually looking at it again. You don't even need to set the position of the subtitles in Dumpster. The ttxt file contains the position too. Just look at the following code from my file:
The translation parameters are already there. No need for Dumpster.

Now I wish there was a way to get rid of Dumpster altogether. Maybe dump the track as xml with mp4box, change its handler subtype to "sbtl" and then import those settings back into the movie file?

Basically there is no limit for the number of subtitle tracks. You can use MP4Box to add a bunch of subtitles. Just indicate the language of the subtitle with the three letter country code (use MP4Box -languages to get a list of the supported country codes). Then change the handler subtype of the tracks from text to sbtl.
Since you most probably want to see only one subtitle track at the same time you need to put them all in the same alternate group. You'll find the "alternateGroup" in each tracks header (moov/trak/tkhd). Each alternate group is just a unique value inside the movie. Since alternate group 1 is usually taken by alternate audio tracks you can take alternate group 2. Just put the same value into all subtitle tracks alternate groups.
That's it. This should work on Windows as well as on Mac OS X. The only difference is how you edit the QT atoms. On Mac OS X you can do that with Dumpster (that's what I'm using). On Windows you can do that with QT Atom Viewer and a hex editor.
I only tried playing that movie on my Mac in Quicktime since I don't have an Apple TV. It works fine on the Mac. I suppose that later firmware upgrades for the Apple TV will fix the subtitle problem you described earlier in this thread.

Did you ever encounter a way to avoid Dumpster altogether? It's useless for automating processes, really.

Muxo is no help as its development has stopped and Handbrake has refused to accept the patches to include this in the program.

I assume either MP4Box or a modified AtomicParsley should be able to set this bit correctly (and I'm half thinking of traversing the sourcecode for mp4box to search for the ttxt atom and change it to sbtl and recompile, just to see how it goes).

Have you found anything on this front?

Well. I have tried.

I have traversed as best as I can the MP4Box code. I can't find which instance of "text" is the one that actually sets the atom's fourcc name.

Since using sed from the command line to replace all instances of "text" (or "0000text0000" if you want to play it safe) works to set all text tracks so they're recognized by apple programs and devices (except for the non-touch ipods) and pre-setting in the ttxt the correct width (full width of video) and height (20% of height of video) ends up giving perfect subtitles, changing that atom's fourcc from "text" to "sbtl" should be enough to create the track properly to begin with (instead of having to run the whole video through a search & replace routine).

I've gone and asked in the sf forums for MP4Box for help on where to locate this fourcc to change it in source and compile a personal version (as I only want to see the videos in Apple devices. I've also separately made a request for an "Apple Format" switch in the app itself. Seeing the activity of these forums I suspect none of these two will be answered.

I am having some problems with using your sed method.
I am using the line:
sed s/0000text0000/0000sbtl0000/ <movie.m4v >movie_sub.m4v

But the resulting fille is unreadable by quicktime or dumpster.

I have also been trying to automate the encoding process, the sbtl part and the automatic positioning of the sub in the .ttxt is still giving me problems.

I have been using sed for a while now, like this:


(part of a larger script I use, right after AtomicParsley and mp4box adding the sub.

I was documenting this yesterday here: http://forum.entropicgarden.com/viewtopic.php?f=2&t=14967&p=15367#p15367

When I got a PM elsewhere pointing me to this: http://forum.doom9.org/showthread.php?t=145192

And then today I got another, to an open source muxo alternative: Subler.

http://forum.handbrake.fr/viewtopic.php?f=14&t=9197

So I'm a happy camper now.

You Sir, are my hero!

I will pass on the subler way, because it uses a GUI.
But I will try to use the C code on my windows box.
The reason I want to use a Windows machine to encode is because my fastest Mac OS machine is a PowerMac G4 450dp and the Windows machine is a Core2Duo.
If there is an alternative to Vroksub (A subtitle downloader for opensubtitles.org) I want to switch the rest of the handling to my Mac machines.

This is what I have so far on my Windows Server (my Mac os knowledge isn't enough to come with a equivalent
