Post by swat03 »

I am newbie of the use of handbrake. It is a great software. I am using window 7 and 0.94 version handbrake to encode some movie with srt subtitle for ipad. It is successfully play on ipad and itunes. But i face one problems is the size of subtitle, it is too small. I would like to know whether there are any setting or method to increase the size of subtitle. Pls advice

Not with HandBrake.

Subler can do it but it's Mac-only; I don't know what Windows-based apps can alter TX3G subs in MP4.

I'm interested in this too, I also have the soft subs working, and also increased the font size in the tx3g subs.
The changes are seen well in iTunes, but on the iPad they just display as their normal small size. For now I think maybe the iPad sub renderer software only has one font size. I searched the net briefly but found nothing, seems for anime and such pre-hard subbing is the way to go although it means encoding twice which sux.
Hopefully a new version of hand break may allow hard subbing of srt files or ttx or something with variable font size. This would make it a lot easier.

Good luck

mp4box can do this. There are several GUI front-ends for it out there. It takes .srt and converts them to tx3g or ttxt.

A single flag in the fourcc when adding these two-identical files will indicate to the ipod whether it's an "ipod optimized" subtitle or not. If it is, then formatting is dismissed, a shadow box surrounds the sub and the size is defined in the XML.

Currently all "converters" add the sizing box for the sub hardcoding the pixel height, which in turn in the iPad turns out to be too small. iPhone 4 extrapolates this to the screen but the iPad doesn't.

The problem seems to lie currently both in the iPad and in converters.

I haven't tested whether if adding non-ipad optimized subs results in better subs. In general these tend to suck anyway.

You are sure the iPad respect the subtitle pixel size? I guess I should "borrow" one and try.

Let us know. I seem to remember you had a comprehensive blog post on all this.
