probably a basic AE fix i am just not getting

Well-known member
so i have been experimenting with twixtor in AE and for some reason when i slow down my footage, the time of the entire piece on the timeline stays the same. so say for instance i have a 10 second clip i slow down to 50%, the clip speed will now be 50% but the clip length is still only 10 seconds, as the second half of the clip has now been cut off. i know its not a part of the composition settings because i made a composition 10 minutes long and had a 3 second clip i was trying to slow down to 20% and it still just only shows the clip at 20% for 3 seconds.
what am i missing here? it is probably some dumb things i just am not thinking of/basic AE setting i need to learn (i am new to AE). as always, thanks
 
It's covered in the Twixtor User Manual. It's the horrible way Twixtor handles clip length. I cant explain the crazy process any better than the user manual.

Honestly, though, I have 4.5 Pro (I think that's the version) and I didnt even install it on my new system. CS3's Time Remapping with Pixel Motion does just as well but is easier to use.
 
Hey Banksie—
I haven't really used Twixtor, but I think you can also apply it to a solid layer or something and have it reference your footage so that you can see durations in a more efficient way? There are tutorials on their site which go into some more detail, but it's kind of like the time remap function in AE. You change your speeds on the graph, which changes the duration of the clip, but this isn't reflected on the timeline. You see the speedramps etc., but the "icon" or piece of footage on the timeline still looks to be the same length. If you made a clip twice as fast, it would play twice as fast, but the "icon" would like identical. When you actually scrub through, you'll find that the last half of the clip is just dead space. Sort of weird. And the CS3 thing mention earlier is not Twixtor related, it's just a newer feature in AE. Now AE has optical flow style handling of time-remapping like Twixtor, but it's a lot less complex. You just time remap your clip and then click the pixel motion checkbox. It can get very "morph-y" if your footage has a low framerate, large motion, or lots of detail (like water droplets). Hope that helps you...
 
i actually meant how AE CS3 handles time remapping and pixel motion, without using twixtor at all, as per you suggestion. as in i will look into that method because as i am learning it might be a little more productive and cleaner looking

It is not how CS3 handles it. It's about how Twixtor works.



RTFM.

thanks graham...do you know if there is a way to change the settings to allow the clip length to change according to the speed?
 
Sorry. I thought you were asking me the exact opposite of what I had just explained.

With Time-Remapping, just drag the end of the clip out. If you have a 5 seond clip that you want 50% speed, you would drag your end keyframe out to 10 seconds. The clip will still show as 5 seconds, but drag the end of it and it will expand to 10. It will actually extend further, but everything past the extended length will just be a freezeframe.

Sorry for the misunderstanding. Hope that helps.
 
Also, I suggest you do a side by side comparison between the two on the specific type of footage you use. For my uses, I found Twixtor both complicated and the results weren't any better than Time Remap. Also, the interpolated frames caused crazy warping, even when I was not slowing down very much. Time Remap can certainly cause wacky warping, but in the same instances I found it to be less than Twixtor. Plus, if there is too much warping with Time Remap, you can easily switch from Pixel Motion to Frame Blending to see if that works better. It wont work for all shots, but it can for some.

And Twixtor might be able to do all this, but I've RTFM 5 times and I cant make heads or tails of it.
 
GageFX - no problem, i know it can be aggravating seeing a relatively new member acting seemingly obtuse.
yeah i tried reading the manual and stuff but it really is goofy and not well thought out. i am actually going to have a go at the CS3 time remapping now and hopefully it will go well. thanks for the help!
