[Xerte-dev] Re: Video and subtitles from external file in Xenith project

[Fay Cross]

Hi Johnathan

Yes, sorry I forgot to say the it only allows flvs and mp3 to be used at the moment - I should be able to change this to include mp4s too but for the moment is it possible for you to convert to flv to get your transcript file?

Also, I listed the video file types you will be able to use in the HTML5 version but different browsers support different video types.  For example, mp3/4 aren't supported in Firefox but will play in IE/Safari/Chrome/iOS while webm files will run on Firefox but not in Safari... it's annoying.

Hello Fay,

The HTML5 version will support mp4, ogg and webm file types

I am finally getting somewhere (I think), having created some test files using camstudio with the Xvid MPEG -  codec. This still outputs in an avi wrapper.

However I have found some free software that will convert it to both mp4 and webM. Both the files play when I open them in VLC media player.

However when I installed Adobe Air and then installed the Transcript Tool (thank you for making that available) I was surprised to find that I could not load either the MP4 or webm files as neither format was recognised as being a media file.

Yet when I open the VLC media player it appears to be filtering on media files and lists both mp4 and webm.

Is this a windows issue or specific to the Transcript Tool?

What, if anything, do I need to do to open mp4 and webm files in the transcript tool?

Kind regards

Johnathan

I have made a simple tool that will make a timed transcript files to go with audio / video files - I'll send you it in a sec.

Not sure about the best way to convert files at the moment though.

Subject: [Xerte-dev] Video and subtitles from external file in Xenith project

I have recently produced some documentation to support the new pages in the next release of Xerte / XOT.

I used Open Office so that
a) I could supply anyone who wanted to translate it with an editable copy
b) so that I could output in pdf format

But it occurred to me this morning that it might be useful to use something like camstudio to create some demo videos.
If I left off any sound and used subtitles driven from an external file (are they subtitles or closed caption?) then it would enable translators to create alternative subtitles.

So I was wondering if any decisions have been made regarding the Xenith project as to what video format would be best to use and if anyone had considered what format of subtitle / close caption file they would want to go with it?

If I am going to have a go at this it makes sense (to me at least) that any end result should work with whatever results from the Xenith project.

As a real long shot has anyone identified any free software products e.g. for generating the subtitle files, converting the video format, playing the video / subtitles?

Kind regards

Johnathan
