[PiTiVi] Transition duration

Hello,

as basic transitions (cross fade) made it into pitivi some time ago, I'd
like to ask for displaying the transition duration so this feature gets
usable to me.

[PiTiVi] pitivi and multiple soundtracks/subtitles

Hello all,

I record TV shows using my freebox [1] and get .ts files as a result. They 
ends up taking a lot of space, and I'd like to regain part of it.

[1] http://en.wikipedia.org/wiki/Freebox

So I would like to split some files and remove commercials. I would also 
like to better compress them if possible.

The files may contain several soundtracks and subtitles. Sometimes, 
network failures cause the files to be slightly or more seriously broken.

My ideal (for now) workflow would be

1. detect file corruptions and warn me or fix them (automatically)
2. pre-detect commercials (automatically)
3. split shows, remove commercials (manually)
4. compress and convert to .mkv (automatically)

I would like the most of it to run in batch mode.

I don't really care to get Matroska files at the end, but the file format 
seems to be well fitted for this task.

Step 2 is optional but I would appreciate any mean to minimize the time 
spent on step 3. As commercials often cause changes in frames sizes and 
resolution, they might be easy to detect.

For step 3, I would try pitivi. I hope it won't loose the additional 
sountracks and subtitles.

For step 4., I would use gstreamer or handbrake. Maybe I should wait for 
them
to support WebM instead of H.264.

I guess step 1 is the tricky one. However, I think that if I don't check 
and fix the files on a systematic basis, I'll get indexes and sync 
troubles at the following steps.

So here are the questions :

- will pitivi and/or gstreamer handle the multiples soundtracks and
   subtitles ts files correctly?

- is step 1 necessary? Do you tool any tool that would do it?

- do you know any tool that would do step 2?

- would you suggest any change in the workflow?

Thanks a lot for any hint.

-- Sebastian

In theory it could; in practice it won't (because it is not implemented
in pitivi, patches welcome, etc.).

Furthermore, your MPEG TS files won't work properly with gstreamer at
the present time, see
https://bugzilla.gnome.org/show_bug.cgi?id=550634

> 3. split shows, remove commercials (manually)
> 4. compress and convert to .mkv (automatically)

You should probably be using avidemux rather than pitivi here, as
avidemux is a bit more oriented for the use case you're looking for and
it allows lossless muxing/transcoding (with the "copy" option).

It would be nice to be able to do everything you describe above in
pitivi someday, but currently, those features are not there.

[PiTiVi] Pushing non-i18n changes to git.gnome.org Re: [pitivi] Deweirdification of keyframes related menu items (prevframe and nextframe)

Hi,

  (cc-ing pitivi devel ml so everybody is reminded)

  The only changes allowed in the git.gnome.org mirror of pitivi are
changes in the po/ directory. Any changes to the source files must go
through the upstream process (where will we accept or not those
changes).

  In the future, please contact the pitivi development team.

   Thanks

  That'll be perfect, then we can just do a git bz apply && git push :)

[PiTiVi] transparent image files

I'd like to be able to import into Pitivi image files in which the background is transparent but, when I try it, the background comes out black in Pitivi.  Is there something I should be doing differently to make that work or is this something that Pitivi can't do yet?

Re: [PiTiVi] transparent image files

I did it with transparent png and svg files.
Sometimes they turned out to be black, but
when u adjust the opacity and set back with the horizontal line,
you can see that it works when you play the movie.
