Describe the issue/problem and steps to reproduce

Using latest git version 025e613, I get multiple videos files created during the same event.

This messes with my database setup since I have multiple videos for the same eventid and eventids should be unique.

Are we supposed to get multiple new files (see /videos/piscine/2022-08-14_08h46min27s_0010120220814084419.mp4 and /videos/piscine/2022-08-14_08h44min17s_0010120220814084419.mp4) during the same event (number 45, eventid=0010120220814084419)? However I get only one preview picture (/videos/piscine/2022-08-14_08h44min33s_0010120220814084419.webp)

[Mr-Dave]

Yes. There can be multiple movies created per event. EventIDs are unique to events not movies

[SylvainGarrigues]

Shouldn't we have multiple best pictures by event then, so that each one corresponds to a movie?

I am using each picture as a preview of the associated movie in my web application, so in this case (see log) I get the exact same preview picture twice in a row for two different movies: how could I fix that?

[Mr-Dave]

That is not how it was designed by the original developers. I'll move this over to a discussion to log it as an enhancement to have a separate best picture per movie.

In the interim, you can try to increase the maximum movie time so that you only get a single movie.
