MKV (H.264, DTS, SRT) to playable format for iPhone, iPad and Apple TV 3

[ScarAce1989]

Sorry for the question but I want to change all my movies from MKV to MP4 for iPhone, iPad and Apple TV 3.

Tried Handbrake, but it takes a very long time om my pc and I don't see Dutch subtitles.
Tried XMedia Recode, but no subtitles.

Maybe MkvТоMp4, but what settings I should use? (I'm a noob)

What is the best solution. All my movies are 720p. I want it compatible with iPhone 4, iPad 2 and Apple TV 3. BEST QUALITY WITH SELECTABLE DUTCH SUBS.

Someone who can help me? BTW I have a windows pc.

You might try MKVtoMP4

Can you help me with the settings?

Just wondering: Don't 'iPhone 4, iPad 2 and Apple TV 3' support 720p video?
If they to a simple remux + may be reencoding of the audio should do the trick.

Do they support DTS and SRT???

[Selur]

sorry, ment reencoding of the audio (fixed now)
srt isn't the problem
a. it's easy to convert it to ttxt
b. mp4box can to the conversion from srt to ttxt on-the-fly during muxing

[ScarAce1989]

Okay I converted the SRT to TXTT with MP4Box using the command MP4Box -ttxt file.srt. Worked but when I tried to view it on the iPad 2 I don't get subs. On the iPhone 4 and the Apple TV 3 I see the subs. (iPhone 4 in black bar, Apple TV 3 without black bar).

Also the Apple TV 3 gives me 2.0 audio, instead of 5.1.

Check screenshot please.

Your settings in mkv2mp4 indicate Output: AAC 2.0, so what did you expect would happen?
I guess you need stereo output, since the iphone might not be able to handle 5.1 audio,...

on the iPad 2 I don't get subs.

which probably means you need another player,..

[ScarAce1989]

Okay it workes now. I encoded 2 movies: Avatar (1280x720) and Batman Begins (1280x536). I got a problem that the font size of the subtitles are different. Avatar has a larger font than Batman Begins. How can I get all subtitles to one size???

[Selur]

wild guessing: look into the subtitle configuration,...
ttxt and srt both allow to specify a font type and a size, so there is a good chance that you can configure that size somewhere,..

[ScarAce1989]

Both files same settings. In Notepad+:

<?xml version="1.0" encoding="UTF-8" ?>
<!-- GPAC 3GPP Text Stream -->
<TextStream version="1.1">
<TextStreamHeader width="400" height="60" layer="0" translation_x="0" translation_y="0">
<TextSampleDescription horizontalJustification="center" verticalJustification="bottom" backColor="0 0 0 0" verticalText="no" fillTextRegion="no" continuousKaraoke="no" scroll="None">
<FontTable>
<FontTableEntry fontName="Serif" fontID="1"/>
</FontTable>
<TextBox top="0" left="0" bottom="60" right="400"/>
<Style styles="Normal" fontID="1" fontSize="18" color="ff ff ff ff"/>
</TextSampleDescription>

[ScarAce1989]

Someone?

[Selur]

assuming the entries are really identical the rendering should be the same unless one of them would need to much space to be rendered in the assigned textbox, in that case it might get automatically shrunk,...

[ScarAce1989]

Uhh think you're guessing. Someone else who know the solution?

[Selur]

There is no guessing involved, if the entries are identical and the text fit's in the box the rendering should be the same.
btw. if you want to know what the settings mean: http://gpac.wp.mines-telecom.fr/mp4box/ttxt-format-documentation/

[ScarAce1989]

I know what the settings mean, I already read it. But is there a way to get them the same size?

[Selur]

same font + same font size + text fits in TextBox -> same size when using the same decoder, unless the decoder is configured to overwrite the specified settings or the settings differ for a specific TextSample-element.
ttxt is a rather simple format,...

it might help to use different width&height values in the TextStreamHeader and TextBox but, since you already read the specification you are probably already aware of that.

can't say anything more without more details.

[ScarAce1989]

What details do you need? Maybe it is something with TextBox. But both settings are the same when I open the ttxt in Notepad+.

[Selur]

What details do you need?

Are there additional font/size definitions in the ttxt files? (e.g. additional Style-elements?)
(size will change if the text element uses a different style,..)

What resolution has you file?

atm. your textBox is:
<TextBox top="0" left="0" bottom="60" right="400"/>
with:

• bottom : specifies vertical extend of the text box (type: signed integer). Default value: 0 pixels.
• right : specifies horizontal extend of the text box (type: signed integer). Default value: 0 pixels.

-> should the text that's inside the text box fit into it?

Have you checked the player software if it overwrites the font or other subtitle related stuff?

[ScarAce1989]

Okay gonna check it. I'm not at home right now.

[ScarAce1989]

Still mo difference. Tried to change Textbox but font size still the same. Still difference.

[Selur]

If all the parameters match I have no clue why your decoder handles the content differently.

[ScarAce1989]

I think it is the different size of the video why it is smaller but I don't know the solution.

[Selur]

only resolution you every told/showed was through the screenshot in post #7 which was 1280x720.
-> I guess what your playback software does is, scale the font size the same it scales the picture, so if you want the end result to be the same you have to scale down the font size accordingly,...

So how do I change the txtt to the right size?

[Selur]

You use a text editor and change the font size,...

Avatar (1280x720) and Batman Begins (1280x536).

since the width is the same I would have assumed that the scaling would be the same since that is not the case the scaling on your playback device seems to be fixed to the height, so if you scale the font size of the smaller by 720/536 or the font size of the larger one by 536/720 they should result in a similar size. (you will probably not get the exact same size due to rounding)

[ScarAce1989]

I tried this but still is Batman too small, no difference.

[Selur]

..., no difference.

Does it change the font size at all? If not than you player ignores the settings and probably has some internal settings how to handle subtitles,...

[ScarAce1989]

Avatar (1280x720) SUBTITLES GOOD FONT SIZE
Batman Begins (1280x536) SUBTITLES TOO SMALL FONT SIZE

No difference at all. I encode with MKVtoMP4 and import it to iTunes and watch it on Apple TV 3.
