25 fps to 24fps to 59.94fps

You may be able to apply time remapping. Keyframe it to skip the fifth frame, then apply a loop_out expression, replacing “cycle” with “continue” so the pattern continues through the clip. Make the graph visible to help you. You may need to change the number of keyframes in the expression, but it’s possible. I’ve done it.

You may also consider rendering to a sequence, then deleting every fifth image in the finder/windows explorer. That’s not as hard as it seems — try arranging the list so the fifth, tenth, fifteenth (etc.) images appear in the same column in the window so you can find them faster. Once that’s done, you re-import the sequence, choosing “force alphabetical order” so it becomes 1,2,3,4,6,7,8,9,11,12,13,14 …

i think i would go the pulldown route at this point.

-import the footage into ae.
-interpret footage as 23.976.
-drag it onto the make comp icon/button.
-add to render queue or make movie.
-set render settings to render fields and pick a pulldown (any should work) — note the frame rate should automatically change to 29.97.
-then render.

OK, I will try the interpret footage – pulldown method…I don’t really know enough about expressions to make that skipping a frame thing work…unless you can give me the quick version on exactly how to do that. So I would interpret as 23.98 and not 25? I guess this avoids having to do time remapping? If all else fails I suppose I can always cut out every fifth frame manually in the avid (yikes).
thanks

my method is slowing the footage slightly, but the result should be smoother.

you could also just drop the 25fps footage into a 23.976 comp. this will drop 1 frame per second. then just render as i described above to add the pulldown.

I’d interpret the footage as 29.97 so it will run a little faster apply CC force motion blur, render out with fields, bring that rendered footage into a 29.97 fps comp, separate fields, then adjust the time by time remapping if needed. There may not be enough of a time difference in these animations to make a difference.

This way you’ll end up with interlaced footage that will time remap much better than your 25 fps footage.

BTW, this is an alternative to interpreting the footage as 23.976 fps, placing it in a 23.976 fps comp and adding pulldown in the render to bring it up to 29;97. The only problem with this technique is that you’ll be mixing film look with video look because it sounds like you’re working interlaced….

I don’t know of a way to do this in AE…

…But, I do know a VERY easy and fast way to do it with Avid Liquid.

Import the footage, then add a strobe effect for every 5th frame. That’s it.

If you have a professional level NLE… you might look for an equivalent filter.

Ooops… never mind… I was thinking about doubling a frame ever 5th frame… hmmm… BUT, it may be possible to use a negative 5 frame strobe effect (sometimes found in a Time warp filter of an NLE) to remove a frame… don’t know… but, it would be worth a try…. specially since it would make it VERY easy to do.

Just a thought…

OK, thanks for all your suggestions.
I will do some tests today.

Hey guys,

I’m thinking of buying a super 8mm camera. I’m hesitant because I live in a PAL country and the camera does only 24fps. There are more expensive cameras that shoot at 24 and 25fps; is that a better option for me?

I know that you can convert the video from 24 to 25fps, but my question is: is it better to do it in post-production or simply shoot on 25fps?

Considering that there are dvd players that play PAL and NTSC, and by shooting on 24fps and then speeding it up, you end up having a two samples of the film footage that you could use.

Let me know what you guy think,
Thanks.

[Lee Imiir] “I’m thinking of buying a super 8mm camera.”

If you enjoy investing in a technological dead-end, by all means, get it. I hope you enjoy the associated processing and telecining costs, which you can’t avoid.

I wouldn’t say that buying a super 8mm camera is an investment, it’s not meat to be; for a film student, like myself, it’s about the passion.

The telecine process is expensive but with $40 I can buy and process a 50′ 64T roll (no sound and in standard def.) but that will do for a music clip or a short film.

[Lee Imiir] “Considering that there are dvd players that play PAL and NTSC, and by shooting on 24fps and then speeding it up, you end up having a two samples of the film footage that you could use. ”

Standard-definition DVD, eh? Does this imply that you will have no need for high-definition?

I know more people that don’t have tv’s then people that have high-def tv’s. But your point is valid.

Thank you for your post, I think I needed somebody to point out the cons of me buying a super 8 camera. I will consider it more carefully and do more research.
