  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Has anyone tried a plug-in such as Twixter to effectively slow down EPIC footage acquired at 300fps?
I've seen the impressive demo's of Twixter with 7D footage shot at 60fps, and was curious if the higher frame rate would lead to cleaner results.
If not, is there another similar product that could reasonably simulate, say 1000fps, with EPIC footage shot at 300fps? I understand that the successful implementation of these programs depends on the nature of the scene, but I am curious if the higher recorded frame rate increases the effectiveness of the end result.
 
Robb, it surely does. The more frames you have, the better the twixtor output. While in 7D footage, for example, to get a 1000 FPS you have to almost slow down in twixtor to 7%, in a 300 fps shot you only need to slow down to about 30%. Much less artifacts, much less information to calculate between frames. Also the Epic shoots 5K, and the extra definition helps twixtor to differentiate the subjects in the picture.

EDIT- However, this never substitutes true high frame rate recording. You'll still get those strange morphs of drops of water or other liquids, or sometimes foreground and background "merging"- not as much as in 60p footage, but it will still be there.
 
The amount of luck that you have will also greatly be affected by the type and amount of movement in the footage. What is actually more important than the source frame rate, is the amount of movement that objects have "between frames" in the source footage. Anything that helps to minimise this will help - of course shooting at the highest frame rates possible will go a long way to achieving that.
 
From experience doubling the frame rate can look quite good, more than that and you have to join the 'it's good enough' crowd. YMMV
 
It works very good...except it performs poorly with liquids.
 
I would say it works for "rigid objects", especially so if nothing comes in from the boundary of the image. But as Paul says, liquids, such as like water, especially with sun ligh reflections creates difficulties. I've also tried what happens when the wings of birds (closed-ups, 125fps) are slowed down, but the outcome was useless. I guess the plug-in was not able to pair the points correctly between two frames, and therefore the results was what it was.
 
Anyone tried slowing down high-framerate footage using Adobe Premiere Pro?

I have taken footage shot at 120fps and a fast shutter (1/2000) and slowed it down about 40% the results are not bad. I will try to find the shot and post it later.
