Just curious. How do you do the voice overs?
I will possibly be classed as an heretic and ready to be
broken on the wheel for
writing this on an LO user list, but IHMO there are much better ways of
slide presentation than using Libre Office.
These days, I use one of the video editors, e.g. OpenShot, to make a
program. The audio is recorded as a continuous sound track, then the
images are dropped
in over the sound, Perhaps it is a voice-under?
However, to answer your query, here is how I worked with LO, and it is
streets ahead of our methods
used 40 years ago, where the audio editor was a razor blade plus a roll
of quarter inch adhesive
tape. Then, the images were 35mm slides, text slides were drawn, then
photographed, and we
prayed that the processing laboratory would not change fluids while
developing our film, thus
introducing colour shifts. On one job they did lose 2 36 shot-films from
a 30+ batch, ruining a
week's work for 2 of our team who were making a training tape/slide
program about measuring
water quality in remote lakes and rivers!
Libre Office. The basic system allows the recording of sound for each
slide, so I did this.
1. Sketch out a story and the sequence of images. Note that the images
need to be ready in
advance and that those with text or stepped bullets should be made
and saved as separate files.
2. Draft a series of descriptions for each image. Record these as audio,
with a good space
between each one.
3. Edit the audio track - I used Audacity here - remove any pauses
and/or hesitations and finish with
a well spaced track. This is then recorded as a sequence of
separate audio files, one for each
slide. While doing this, note the time/length of audio for each
slide. Audio should be recorded
in .wav format. Best to leave a short silent period at the the
beginning of each file so that viewers
may look at a slide for a few seconds before the audio sarts
4. Now put the sequence together, assemble the slides with display times
longer than the timed
audio sequences. Then embed the relevant audio file for each
slide. Probably the start and
finish visual slides will not have audio.
5. Finally, run the whole program and perhaps adjust the transition
times for each slide. I usually
made the times a bit longer than needed, then pruned them at the end.
Awfully slow and only worth the effort, if the result is to be of
benefit to many.
