Infoseite // Why 50p 25p material in a composition will be shorter?



Frage von Tuffy:


Hi,

is not a real problem, but I simply ask myself.
I work with grad 50p material. If I in After Effects on the Composition 25p change (nothing else), the footage will be shorter (a few frames, maybe half a second).

I wonder why? Should they not remain the same length? There are indeed only a few frames per second playing - I would have thought now, he "throws" Picture every second away (until I have the time or so alters with time remapping).

Greetings!

Which encoding format and what the original format?

Antwort von Tuffy:

50p material is of such a HDSLR - if I now have everything in my head is in front of the ProRes LT.

I prefer the clip on the "New Composition" button, and then only alters the frame rate and * bing * - a bit shorter.

It does not bother or anything, I just wonder about the origin:)

Greetings!

Antwort von WoWu:

Which codec comes from the HDSLR and happens already at the transcoding (170 Mbit / s) ProRes or within the procedure, so LT is still ok in 50p and then only at shorter conversion to 25p?

Antwort von Tuffy:

Hi,

So, the way is as follows:

HDSLR-> convert h.264-> Mac moves to ProRes 50p-LT> the whole thing on my PC.

Say it is really only shorter and only then if I change AE in the frame rate of Komosition - not before. Just within the composition.

Greetings!
