HOW TO MAKE A DVD WITH SELECTABLE SUBTITLES ON MAC OSX WITH FFMPEGX
This guide provides a step-by-step process to convert a movie into DVD format and to add to it selectable subtitles (that is, subtitles that you can switch on or off with the "Subtitles" command of your remote control, and which are not burned with the video).
You have an .AVI DivX, a Quicktime .MOV, a VOB or MPG movie and you want to encode it into a DVD with ffmpegX and add it selectable subtitles for playback on a standalone DVD player.
Open ffmpegX and drop your movie file to ffmpegX icon or "Open" field or "From" area to open it, or click the Open.. button to locate the file from your hard disk.
A default "Save as..." name is set by ffmpegX. If you want to change it, edit the Save as.. field or click the "Save as.." button to choose a location and name for the output movie. If you don't add the file extension (.mpg), ffmpegX will add it automatically at encoding time.
Choosing the preset:
Click the Target Format pulldown menu in the Summary tab and choose "DVD ffmpeg" or "DVD mpeg2enc" quick preset. Please note that DVD image size is standardized to a fixed value no matter the source image size. Black bars are also automatically added by ffmpegX if you use "Decode with Quicktime". If your TV has a 16:9 aspect ratio, select "DVD 16:9" in the Autosize popup menu to set appropriate flags.
If you don't need subtitles, skip to the following step "Encoding".
To add a selectable subtitle, open a .srt or .sub text-based subtitle file in the "Load subs" field (Filters tab).
Use the "Preview" button to preview and check subtitles sync with the audio track. It is not needed to define a color palette for selectable subtitles (a white default palette will be used). If the subtitles are not in sync, use a program like SubSyncX to sync them.
Click the "Encode" button.
Encoding takes places in ffmpegX Progress window.
You can continue working with other applications while encoding. OSX Unix core reallocates processor ressources in realtime as needed.
Locate the encoded files by clicking the icon. The DVD structure which you need to burn is the directory named movie.DVD and containing two folders named AUDIO_TS and VIDEO_TS.
You may use Apple DVD Player to preview the VIDEO_TS folder and make sure that everything is in order before burning. To switch subtitles on/off, use the Subtitles button (top right button in the small drawer to the right)
If you burn with Disk Utility, use first ffmpegX "DVDImg" tool to convert the MOVIE.DVD folder into a disk image file. To do that, select the "Tools" tab, locate the MOVIE.DVD folder in the first "Browse.." field of the "Video tools" area, then click the "DVDImg" button. You will obtain an .img file that you can burn with Disk Utility "Burn" button.
If you burn with Toast®, select the "DVD-ROM (UDF)" option in the "Data" tab, (don't select "Video" as it will unnecessarily re-encode your video again) then drop the MOVIE.DVD folder on the window and burn.
