Right-click on the video clip and click the Time Stretch button in the Time option. How do you slow down video in After Effects? To adjust the playback speed of your Reel, locate the Playback icon (1x, right below the music icon). How do I change the speed of a pre recorded video reel? Start recording your slow motion video by tapping the red colored record button.Swipe to right and you will see SLO-MO out.At the bottom of the screen, you can find some text like: PHOTO, SQUARE, PANO etc.For instance if you're filming somebody playing soccer then running down the field may take a long time and you could speed that up.Then show normal speed for a bit and then show them shooting a goal in slow motion. Sometimes you want to use both portions that are slowed down and portions that are sped up. You can do that on any of the current iPhones. (music)Īnytime you're slowing things down it's best if you're using video shot at greater than 30 frames per second. Grab this part of the sequence there and then slow that down as well. Then I'm going to do the same thing here. But instead of speeding it up I'm going to go and slow it down. Hold the r key down and drag and get to the point where he returns and set that up with speed. I want to get to the point here where he's about to go into the air. It's the same technique here you're just going to make it slower rather than faster. So here's some skateboarding video and there are portions in it where it would be nice to slow it down when the skateboarder is up in the air. Of course you can also use speed ramping to slow things down so you could create a slow motion area inside of an action sequence. Now I have two sections of faster speed in here.(music) Then I can go another half second and grab another two seconds there and speed that up eight times as well. So I can grab about one second in, hold the r key down and grab four seconds in there. Each one of these frames shown here is about two seconds long. So I can speed things up a lot by grabbing sections of this and making them much faster. Here's a twelve second sequence that seems painfully slow watching these skiers go down the hill. Sometimes you can use bursts of speed like this through a long sequence to speed things up. It's not going to suddenly jump to the new speed. It looks about two seconds at the beginning at normal speed, then two seconds incredibly sped up, and then two seconds at normal speed again. Now the entire things is six seconds long. So you want to drag the point at the end of the sequence here. I can actually drag those points to speedup the area in the middle there or slow it down some more. I've got points here at the beginning and at the end. If I was slowing things down it will show a turtle. I've got this little rabbit here showing speed. So I'll go to Fast and you can see it divides everything up. Now when I set the speed I'm only setting the speed for that range. So now I've selected this range here that's in the middle. So holding down r I'm going to click and then drag, this whole time holding the r key down, and select a large portion of the video. I'm going to hold down r key on the keyboard. So after a few seconds at the beginning here I'm going to want to start it here. The way to do it for part of a clip to ramp up the speed and then ramp it down again is to select an area of it. But I don't want to do it for the entire clip. Normally to speed things up in iMovie I would select the entire clip and I would go to the Speed control here and I could change the speed to Fast or Custom and set the speed there. But I could just speed the entire thing up be I think it works better if I show a normal pace and then speed things up to get through the maze and then go back to normal speed at the end. It's basically video I've filmed of just going through a little hedge maze and it goes just a little bit too slowly. Okay, so to start I'm going to drag and drop a simple video in here and put it into the iMovie timeline. So speed ramping is a technique used in feature films where things will speedup during an action sequence and then maybe slow down and then speedup and slow down to pace the action just right.
