Thanks Alan for your useful informations about subtitles
formats and conversion,
Concerning Brian question about video support in Transcriber,
the new version has obviously been delayed once again; anyway
there is a limited video playback integration in the small update
to the 'legacy' version I posted recently on the list:
There was already a limited video playback option relying on QuickTime
for Windows and Mac versions (which are highly outdated now, BTW),
and it has been extended to Linux through 'mplayer' video player (that
needs to be available in the shell standard path). In this later
case, play/pause buttons should also control the video playback,
but the audio still comes from the waveform, so there is
a desynchronization between audio and video that can be
rather annoying (the mplayer versions I tested did not allow a
precise enough control of the seek).
Here is the process:
- you need first to extract the audio stream from the video into a
format that can be read by Transcriber (no automatic extract, sorry!);
- open the audio file in Transcriber;
- then open the corresponding video file using File/Open Video File...
I tested it with MPlayer 1.0rc1-3.4.2 version under Linux.
Older versions did not provide the time code information, I hope
more recent versions did not change the communication protocol...
For audio track annotation of video recordings, it may sometimes
