Bug Description

Hi,

Don't know if this is a bug or a feature request.

OpenShot is an excellent program, for me the first video editing program under Linux that works (well, nearly works, please read on).

My use of OpenShot is to import an mpeg2 video (recorded with MythTV), to cut out the lead-in, lead-out and commercials. Then export (transcode) the video thus obtained (to mpeg2 again). For export I use the "Simple Profile": All Formats | MPEG (mpeg2) | DV/DVD Widescreen PAL | Med.

Whatever I try (do I overlook something?), I can't get rid of the deleted clips (the commercials, etc). Yes, they are deleted all right, but after the transcoding process the deleted clips still turn up as a black screen. So the transcoded video is roughly speaking the original video with the deleted clips shown as a black screen.

The MS Windows video editing program I used until now, simply skips the deleted clips upon transcoding and what remains are the clips I want to see, concatenated together.

So, in OpenShot, I now shift the clips I want to retain to the left and concatenate them. Then the deleted clips are at the end and after transcoding they keep coming up as an extended period where a black screen is shown. For the time being, I live with this, but to my opinion this is not elegant, to say the least.

Oh yes, after deleting and shifting clips, I save the project as a new project, because only at that time I know the maximum length (duration) of the transcoded file I want to see and it is my understanding that upon creating a new project you can specify the maximum length of the transcoded file. No use, the deleted clips keep getting transcoded (as black screen).

If you are really of the opinion that this functionality is correct, then please add a checkbox in the Export Dialog where the user can turn off transcoding of deleted clips, because I can't imagine that I am the only user who finds these black screens unacceptable.

Some more usage data.

OpenShot, version 1.4.2.
Linux distro: openSUSE 12.1.

Kind regards and good luck with further development of OpenShot.

Yes, export including deleted clips remains possible, even after shifting the remaining clips "to the left", but let's call it "beginners bad luck" that I stumbled into it. In the meantime I know how to export files without the deleted clips, so let's not try to repair some seldomly occurring situations.

As far as I'm concerned, the only thing that remains is a feature request (but for me it has no high priority now that everything works fine): after deletion of clips and before export of the remaining clips it should not be necessary to shift these remaining clips "to the left". The export process will simply skip the deleted clips.

I tagged on Whishlist even a part of this issue comes from MLT.
A lot of things will be possible when our framework will be finished and jump at him.

I'm not 100% clear on what you are describing - are there gaps left on the timeline where the deleted clips were? If so, this is why the black screen shows up in the exported file.

But, also, there is a new feature that has been committed to the trunk (but not yet released) that will close the gap when you delete the clip if you press the shift key while deleting.

I modified this a bit, to also shift transitions that come after the gap (since they almost always line up with the clips).
