Alpha is available for DVD subpictures.

DVD subtitles are made of BMP or TIF files with a 4 colour max.
Those colours are transformed with a 16 colours palette and possibility of transparency.

Ok, ok.

I guess I know where my confusion comes from : satellite receiver and subtitles on live shows ???

Bmp so no alpha gradient on DVD.

Gérald,

They are always images: BMP for DVD and PNG for Blu-Ray.
The dvd/bd player or a software render them as they are embedded. The only thing that can be done is resizing or changing the position.

Hi Gérald

All the subs I've ever seen on DVD/Blu-Ray have been images.

Hi,

Are subtitles always Images on dvd/blu-ray ?

Did I dream or they are not always rendered the same according to each dvd-player or software-reader on pc ?

Hi Manuel

I don't like the subtitles being burnt in by dvdomatic, but it gets
the job done.

I am working on making that better (slowly).  One problem is
that DVD subtitles are images, so you need some OCR to get them
as text for a DCP.

Best regards
Carl
