BMP to SUP

[Amnon82]

Hi there.

I was asked once if its possible to add a logo to a movie without reencoding the Videostream.

I told him that it is possible adding a Subtitle to the Movie and displaying it over the whole movie.

Till now I only find a way using normal text for a subtitle.
But then I found out that also BMP is used for subtitles.

So now my question to You guys:

What is the easiest way getting SUP out of BMP?

Hi,
Have you checked out the DVD Subtitle Tools package?

Please refer to my post in thread 59952.

It's the 6th entry in the thread which highlights using
DVD Sup Tools (commandline programs), which I believe is a
convenient way of extracting subtitle / subpicture bitmaps from
.sup files, preserving the color mappings and timings.

You can convert .sup to .bmp / .txt (MicroDVD format) with DVDSupDecode.
You can view the details of the .sup files (timecodes, view bitmap,
etc.) with DVDSupHTML.
You can convert .bmp/.txt(MicroDVD format) back to .sup with DVDSupEncode.

So, you now can easily replace / edit the bitmaps and timings
to your liking and generate new .sup files with the original color
mappings!

DVDSupEncode produces DVD-compliant .sup files which can be
re-muxed into a .vob file, ready for authoring / burning to a new
DVD.
