DivX, keyframes et VirtualDub


 Share

Recommended Posts

Salut...

 

Une ch'tite question. Je possède un DivX que je veux découper à un endroit particulier, et VirtualDub refuse, me le redécoupant à la keyframe la plus proche. :nerveux:

 

Comment éviter cela, :??: y-a-t'il un moyen de redéfinir les keyframes dans un DivX ou est-ce juste une option de VirtualDub à modifier ?

Extrait de virtualdub.org :

 

I tried to cut out some frames in direct stream copy mode, and VirtualDub put them back in!?

 

You deleted a frame, but didn't delete the non-keyframes after it.

 

A keyframe is a frame that can be decoded on its own; a non-keyframe, or delta frame, is a difference from the previous frame and cannot be decoded if the frame before it is missing. VirtualDub always plays it safe and makes sure that all frames that you don't delete are decodable. This means that any non-keyframe that you include will force inclusion of any frames before it, back to and including the previous keyframe.

 

Rencontrerais-je un problème sans solution ???

La 1.4.10...

 

Mais si tu relis la citation de VirtualDub.org, c'est tout à fait normal que le logiciel ne soit pas capable de couper un divx sur une frame qui n'est pas une keyframe...

 

Quant à mettre keyframe à 1, j'ai bien essayé en recompressant le divx que j'ai, mais VD me refuse de faire cela, prétextant qu'il n'a pas le log :??:
