@marc-m Hi, for each event/track you have multiple keyframes, you only want the one at the start on each track

@lan-mLMC I think the 'disaster' they're ref to is when the cursor isn't at the start the cube is a mess, this is because every track has multiple keyframes for positioning

Merci à tous pour vos réponses et surto ut merci à Lan-mLMC pour sa traduction, car je ne comprenais rien aux réponses précédantes. Du coup j'ai regardé piste par piste et sur mes 6 pistes du cube, il n'y a aucune images clés. Les images clé ne sont que sur la piste 1, qui est la piste mère...

Thank you all for your answers and especially thank you to Lan-mLMC for his translation, because I did not understand anything from the previous answers. So I looked track by track and on my 6 tracks of the cube, there are no key frames. The keyframes are only on track 1, which is the parent track...

@marc-m There's keyframes on every track where the keyframes can be seen, The Parent track only has 1 keyframe at the start.

This is the Parent track with just 1 keyframe.

Tu as raison, c'était pas dans les zones de recadrages , mais dans "mouvements de la piste"Tout est presque ok, cepedant la face blanche"Devant" se barre dès le début de l'animation.Si je regarde la piste la Zone z= -540 se remet à 0 et le X à 1080.

@marc-m 

1. On all tracks delete all the keyframes except the one at the start.
2. Turn off sync cursor
3. Put the cursor at the beginning of the timeline,
4. Put all the settings so they are correct to make a cube, ( -540, 540 etc)
5. Then use the Parent track to rotate the cube.
