I'm working on a video that was given to me by a
film maker, it's an MP4 file and it has subtitles, the subtitles were given as a
separate Excel file. Does anyone know how I can use the .xls file as subtitles for an MP4,
or even to use it to make a new MP4/MKV file with subtitles embedded?
What Lilian said.
In general:
DCP-o-matic version 1.xx (current 'official/release version) will only create burnt-in
subtitles from bitmap subtitles included in supported container file formats for video,
audio and subtitles. A typical example is an MKV file containing video, sound, and
subtitle bitmap images from DVD or BluRay. There is no way to import the titles as an
external file with DCP-o-matic 1.xx.
That means, if you want to create a subtitled DCP from separate files with DCP-o-matic
1.xx, you first need to 'multiplex' the subtitles into your source footage with
suitable tools. In your case, that tool will also need to create the subtitle bitmap files
from a text file.
(Carl - can you tell us which container/file formats including bitmap subtitles are
supported? I always found this a bit of a mystery...)
When I say 'burnt-in', that means the subtitles will become part of the picture,
and can not be disabled. This DCP can only be shown with the subtitles. If you want a
version without subtitles as well, you need to create a second DCP without the subtitles -
eating up twice as much space all together.
Now, unlike version 1.xx, preliminary DCP-o-matic v.2 is able to create SMPTE subtitles
the way the big boys do it, as a text-file that is rendered to visual subtitles by the
projector at show time. DCP-o-matic v2 is able to use externally supplied text files. But
not your Excel file, unfortunately, so you need to convert it before hand as well.
I have not played too much with v2 and have no knowledge which file formats it actually
supports for subtitles. I understand that Carl probably does not intend to make
DCP-o-matic a full fledged mastering solution including a subtitle editor (although I
think that would be great). So I guess we will always need to find ways to convert
subtitle files from various sources and in various formats. And DCP-o-matic probably will
only support a small number of formats, maybe only 'the one'.
