OpenShot Video Editor

export - audio without moving video

Asked by Paul Mirowsky

An original video is too long.
I am breaking it up into 4 separate videos, each with an opening title, a jpg and then the video portion of the original selected as a track, then a closing title and the same jpg at the end.
There are interspersed jpg throughout each of the 4 shorter versions.

The 1st short using the original starting point of the imported video and outputs correctly resulting in title, jpg and then proper mix of moving video and sound in sync.

The 2nd short using the spliced starting point of the imported video outputs incorrectly
The results are a correct title and jpg followed by a still of the clip beginning at the spliced starting point of the imported video for every frame after. Sound is produced correctly.

Image in/out of jpg files that are added during the separate videos occurs correctly in both the 1st and 2nd short output.

It is as if the png used in the program from the "Project Files" tab is being used instead of spliced original point.

Is this possible?

For reasons I'm not sure of, 1st short now has a delay of video during editing and in output when going from jpg to video. Sound begins with video start correctly, but video remains a still image until approximately 10 seconds passes on 'Zoom Slider' scale.

It should be noted that when clicking on 'Zoom slider' to position 'Play' button, I am constantly using 'Seek Backward' button to re-align video with audio.
This trick does not always work. In which case, if I 'Zoom Slider' to beginning of video, audio will act as if I did not go back and continues from last stop and video starts at 'Zoom slider' beginning point.

?missing clear audio buffer and/or over write by starting audio here?

Example: Click on 'Zoom Slider' at point I would like to see. Click on 'Seek Backward', Click on 'Play', Click on 'Play'.
