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 assembling a
slide presentation than using Libre Office.

These days, I use one of the video editors, e.g. OpenShot, to make a synchronised slide 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.
