What does the Project X colours.tbl actually do to the subtitles?
I import DVB .rec files from my Topfield TF5100PVR Masterpiece PVR/DVR (Personal/Digital Video Recorder) to the computer.
I then author the .rec as a video-DVD with iTV2DVD with the converted DVB subtitles (or teletext subtitles) and chapters at 10 minute intervals.
Our local TV channel recently changed its DVB subtitle color tables. So now the converted subtitles are not so good as they used to be.
Project X (in iTV2DVD) uses colours.tbl when demuxing the subtitles form the DVB. Currently the best table is as follows but it still has some artifacts:
I haven't found a definite guide what those lines actually do. This is what I do know:
- model=final colour link depth of this table in bits (2, 4, 8) (means max. 4, 16, 256 paletized colours, best value depends on broadcasters std. table)
- 0..x=ARGB (alpha,red,green,blue as 32bit uimsbf, 8bit each) (undefined colour links are fully transparent). For example FF9C9C9C means:
FF hexadecimal alpha channel = 255 decimal opaque color
9C9C9C = 156 156 156 for RGB mid-gray
0=0 nonvisible title background
But what do the other lines do?? I suspect that lines 1-7 might affect the font's edges (outline outer edges vertical, outline outer edges corners etc or something like that...) and lines 8-13-15 the font's body.
Any info would be greatly appreciated because by trial and error I can't fine-tune the output.
