- VobSub
- Project-X
- TSRemux
- mkvtoolnix
- AviSynth
- ffmpeg (WinFF)
- Son2VSub
  　
Assume the video files are recorded and are in
- D:\temp\~DATA\DATA00.trp
- D:\temp\~DATA\DATA01.trp
- D:\temp\~DATA\DATA02.trp

Join the 3 trp files into one.

DATA00.trp

DATA01.trp

DATA02.trp

d:\temp\~DATA>

Extract subtitle information:
- Open Project-X http://sourceforge.net/projects/project-x
- In menu Presettings -> subtitle tab:
  - Simulate DVB subpictures IRD color model, choose NRX
  - tick "additional export as VobSub (idx+sub)
    
    　
  - Choose to export only subtitle
    
    　
  - Add final.trp, choose Quick start
    
    　
  - You should be able to see many files generated.
    Keep only final.sup.sub, final.sub.idx and remove other files generated
    　
Use TSRemux to convert the final.trp to final.ts.
Choose only 1 video and 1 audio stream.
Note: for audio stream, the one with smaller number is the original language.

Adjust the subtitle color:

Open the program SubResync in VobSub.
Drag final.sup.idx into SubResync.

Quickly browse the subtitle, you will find some of them are not very clear:

To fix this problem:

Save the subtitle in DVDMaestro format in a separate directory, say "son".

In son\final.sup.son, modify it from:

Directory .
Subtitle final.sup
Display_Area (0 2 719 575)
Contrast (15 15 15 0)

SP_NUMBER START END FILE_NAME
Color (1 14 0 15)

Contrast   (15 15 0 15)
Color       (1 2 0 3)

SP_NUMBER START    END        FILE_NAME
0001  00:02:44:13  00:02:46:06   final.sup_0001.bmp
0002  00:02:46:10  00:02:49:03   final.sup_0002.bmp
0003  00:02:59:21  00:03:01:05   final.sup_0003.bmp

Note that color with index 0 is a transparent color.
　

Start the Son2VSub program.
Open the son\final.sup.son directory.
Change the output from 720x480 to 720x576

　
In the output file son\final.idx file, change from

# The original palette of the DVD in PGC#1
palette: 000060, 2b2b2b, 2c2c2c, 353535, 535353, 414141, 626262, 7c7c7c, a9a9a9, c8c8c8, 8f8f8f, ebebeb, b8b8b8, dbdbdb, 9c9c9c, 2b2b2b

to

# The original palette of the DVD in PGC#1
palette: 000000, 000000, 000000, ffffff, 535353, 414141, 626262, 7c7c7c, a9a9a9, c8c8c8, 8f8f8f, ebebeb, b8b8b8, dbdbdb, 9c9c9c, 2b2b2b
　
The subtitle now looks better:

Adjust the subtitle time:
- Find the first subtitle in final.sup.idx
- Play D:\temp\~DATA\final.ts in Media Player Classic (in K-lite Codec pack).
  Play until the first subtitle is heard. Write down the time of the first subtitle.
- In SubResync, right click the subtitle chosen 2 times, until seeing the red triangle
- Enter the correct time of the subtitle chosen. Save as final.idx
- Reopen final.ts in Media Player Classic. The subtitle time should be correct now.
  　
Find the cropping details for movie, in Virtual Dub.
- In D:\temp\~DATA\, create a file called final.avs (using notepad) with the following content:
  
  DirectShowSource("final.ts")
  LoadPlugin("c:\Program Files\K-Lite Codec Pack\Filters\vsfilter.dll")
  VobSub("final.idx")
  　
- Drag "final.avs" into Virtual Dub.
- In Virtual Dub, "Video" Menu, choose "Filter".
- Add "Null Transformation"
- Choose "Cropping...".
- Determine the cropping details (i.e. Write down X1, X2, Y1, Y2. Note they must be even number):
  
  　
Using ffmpeg to convert final.ts to XVID encoded (MPEG4) AVI file final.avi:
- Start a command prompt.
- type the following:
  - d:
  - cd d:\temp\~DATA
  - "C:\Program Files\WinFF\ffmpeg.exe" -i final.ts -vcodec xvid -vtag XVID -deinterlace -croptop 76 -cropbottom 76 -cropleft 4 -cropright 4 -s 640x360 -qmin 4 -qmax 4 -bufsize 4096 -mbd 2 -bf 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -g 300 -acodec mp3 -ar 44100 -ab 128k -ac 2 final.avi
- Note:
  - replace the value for croptop, cropbottom, cropleft, cropright with the values found in Y1, Y2, X1 and X2 found in Step (8).
  - for the best quality video, set qmin, qmax to 1. (the smaller value the better video quality)
  - -g 300 means for every 300 fames (12seconds), there is a I frame. Set to a smaller value if you need to editing.
  - the above example uses 44100kbps, 128kpbs 2-channels mp3 audio. you can modify as your wish
    　
Merge final.avi, final.idx into final.mkv
- Start mkvtoolnix\mmg.exe, add final.avi, final.idx. Press "Start muxing".
