30fps footage, twixtor, after effects, and time.
Hello everyone,
I have a strange dilemma if you may call it. I shot a series of clips at 30fps, 1/160, ISO at 400-640. Now I know or came to realize at exactly 4am that I forgot to speed up the shutter for slow motion.
Here is where it gets weird, all those clips combined have a running time of 5mins:28:20. The clips were combined to a single neoscene avi file. I throw the clip in After Effects, I twix’d, by the end I have about 14×2 key-frames, reason why I say X2 is because there are 14 sets. A start point(20% speed) and finish(100%), 14 times, so altogether its 28 key-frames.I hope I haven’t lost anyone yet.
I open premiere, I line up all clips and at 4:52:22 the shot is different to when I compare it to after effects’ time. If I disable the plugin by clicking the FX toggle then the shots match up(look the same).
I realize this has to do with me slowing down the footage too much… something to do with frame interpolation. I have my Frame Interp. @ Blend.
I’m I stretching this too far? How can I fix this that when I slow a point of the clip down it just extends the frames(clip) past 5:28:20? Is the trick or magic to slow motion in the shutter only? I got this to work before with a shorter 19sec clip so I have no idea what I 5min would react to all the key-framing. https://vimeo.com/11100929
I know in premiere when you slow down a clip it gets longer in the timeline but this is a single clip in after effects using twixtor. Anyone have any ideas? Please do let me know if I didn’t get my point through.
Thanks.

Before you panick
In AE set the project preference to display in Frames
In Premiere, over the timeline on the left (where it displays timecode) – set the time display to FramesNow at Frame N in each, are you on the same frame?

its not that I am having issues with matching frams its because techically my clip is 5:28 but towards the end there are credits. If the FX are active I never get even close to the credits. Its like the clip is at 4mins and change. It’s stuck in time? :/

and I did set Project Settings as you instructed and still no effect.

You mean the sequence is too short?

thanks for the post in the support FAQ, it seems to work. Yes my sequence/timeline was shorted by slowing down the video.
