mp4tools subtitles don't work with VLC?

[orbitalpunk]

Hi,

So when I encode a .MKV with MP4Tools and add an .SRT file, it outputs as a .m4v file. When I play it in VLC, the subtitle text size cannot be changed. Its very tiny. I used media info to see what the subtitle format mp4tools generates and its .ttxt . I tested this in mplayerx and it can adjust the subtitles just fine. So either vlc needs to handle .ttxt or is there a way that mp4tools doesn't strip the .srt file? Its making subtitles in vlc unchangeable.

Try add the srt to the mp4 with Jubler and see if it makes any difference in VLC Media Player.
