Jonas was being characteristically kind. Slow motion has been around for more than 100 years. You could have researched this easily before planning your session.
The only ways you can create smooth slow motion is to have more discrete slices of time or use very expensive software to fake it for you by recreating every pixel of every frame to compenstae for the frames you failed to shoot. the term expensive is used to describe third party tools from the likes of ReVision or the time required to use Apple's SmoothCam Optical Flow or a similar product from Adobe.
Thank you for your responses. I thought pixel motion and frame mix were options for achieving better slow/fast motion in AE. But for some reason I can't see any change in my footage when I change the frame blend mode. The falling object will not blend in to other frames but rather stay still for several frames and then move and stay still again.
Are you doing a final render or a Ram preview, if you are doing a Ram Preview you have to turn on the Frame Blending Switch on the time line ... (the icon looks like film strips) ... otherwise you wont see the results.
If you're ever going to shoot footage that you want to slow down again make sure you shoot interlaced. This gives you 50 fields per second (or nearly 60 in NTSC land) so you'll get much better slow mo.
The technique goes like this.
- Shoot Interlaced footage
- Seperate fields in AE properly. 3rd party plug-ins can do a better job if you have the budget
- Drag your footage into the new comp window to create the proper length comp
- Open up the composition settings and double the frame rate. This is easy if you just highlight the field, move to the end of the numbers and type *2. AE will do the math for you.
- Render this footage to a lossless codec. This will give you twice the number of frames to work with
- Do your time stretching with the rendered footage. Here also, 3rd party plug-ins will do a better job
Thank you very much guys! I will try your suggestions. I really appreciate your help!
Here's how I did slowmotion with that camera a while back:
