  • How do I slow down 25P to 24P in AE ?

    Posted by Derrick on December 19, 2006 at 6:20 pm

    Hi there,

    I’m wanting to buy an HVX200 camera, but the one in South Africa shoots 25P, not 24P like the American version.

    Could someone please tell me:

    1. Will slowing down the footage to 24fps look the same as recording it on the 24P HVX200?

    2. How can I do it in AE to test the results?

    3. Does the 24P HVX200 footage have more of a film look (not contrast, grain, cinematography, lighting, etc…) I mean motion wise (if that makes sense?)

    thanks for your time,
    Derrick

    Are you matching sound to the 25p footage? You can always slow the footage down to 24p and put into a 24p comp to render.

    BTW by “slow down” I mean reinterpret to…

    Thanks Andrew,

    Yeah sounds gotta slow down too. Don’t the hollywood people do that sometimes, I’m sure the NTSC version and the PAL version for example isn’t the same length due to the frame rate difference.

    Does the same apply here between 24P adn 25P?

    I want to buy a camera to make short movies. 25P motion just still looks a bit “real life” compared to 24P’s more “Story” look if you understand what I’m saying?

    Uhm… you’re aware that all movies shot at 24 fps are sped up to 25fps for a PAL DVD?

    So if you feel that the latest X-Men or Lord of the Rings looks “reality TV” and not “story” you’ve got a point.

    Other than that, I’d leave it alone and shoot and post at 25p. I’m quite sure nobody will notice. The only reason you’d slow down to 24p is for a transfer to film, in which case I’d post at 25p and deliver to the transfer house like that – they do 25 to 24 all the time.

    yeah Dave, Barend I hear what you are saying.

    I’m being overly critical without knowing to much about the subject. And for workflow’s sake in South Africa 25P would make more sense.

    Thanks,
    Derrick

    P.S. just some interesting reading:

    “Video’s frame rate being as close to reality as we can discern jibes with our ingrained perception of how video is traditionally used: to document real-life events.

    The TV news, reality TV shows, and our own home movies have a documentary quality to them that subconsciously suggests to the viewer that they are seeing actual events.

    Even sitcoms and soap operas are less like movies than they are like simulations of being in a studio audience watching a live performance. Video clues us in that we are watching reality, and by showing us everything, it invites us to passively absorb it. : OVERVIEW Movies are anything but reality. Ironically, by showing the audience less (40% of the temporal information of NTSC video), they trigger a part of our brains that works to fill in the missing information.

    In this way film creates a more participatory experience and at the same time informs its audience that what they are viewing is an authored, narrative work. This is backed up by our historical associations as well we have learned to associate film’s flicker with storytelling and video’s unflinching detail with reality.”
