Transcoding Partial Extract ignores "From" field

[mick129]

When using the Streaming/Transcoding Wizard I enable partial extract to break a movie into smaller segments. Each time, it ignores the From field and encodes from beginning to the value in the To field. Is there a work around for this?

I'm using VLC 0.8.6a on Mac OS X 10.4.8. I'm not transcoding the audio or video, just trying to break up the movie. I tried selecting different encapsulation formats, reseting preferences, but no luck.

You can try doing it using the command line:
vlc --start-time <time in secs> --stop-time <time in secs> <input> --sout "<blabla>"

[mick129]

./VLC --start-time 5:00 --stop-time 10:00 /Users/mick/input.mp4 --sout /Users/mick/output.mp4
... gave a clip from the beginning to 38 seconds.

./VLC --start-time 300 --stop-time 600 /Users/mick/input.mp4 --sout /Users/mick/output.mp4
... worked the same way as the GUI. The output file started from the beginning of the movie and went to 10:20.

What format is expected for time in seconds?

[dionoea]

2nd format should be alright. Does vlc --start-time 600 <the video> start playback from the 10th minute ?

It's a total hack, and you probably figured this out...

But after you click finish and the transcoding begins, you can immediately click on the spot on the location slider. Transcoding will commence from where you drag the slider to the endtime you specified for the partial extract End field. It got me through a jam, at least...

As a note for followers, in order to play a dvd chapter from a certain start time (s), this worked for me -- the key being dvdsimple, instead of dvd://

$: /Applications/VLC.app/Contents/MacOS/VLC --start-time=5 --stop-time=10 dvdsimple:///Volumes/Dvd_name@4 # chapter 4, start at 5s, end at 10s

For some reason using --start-time=5 with dvd:// doesn't work [at least for me]
Any thoughts?

The proper time format for Partial Extracts is in seconds.

e.g., a partial extract from 02:00 - 02:45 would be 120 for the start and 165 for the end.
