Slow-mo effect?

how can I make a slow motion effect that changes the pitch and speed of my clip?

did yu try the pitch shifter plugin?
Also you can time stretch the clip.

Slow motion effect results in an unwanted high pitch sound

whenever i apply the fast/slow/reverse effect to a clip, a high pitch sound is created...how can i get rid of this without extracting the audio of the clip (there is no high pitch prior to applying the slow effect)?

Hi Darin,
... changing the speed of a clip HAS to change the pitch of audio.... have a look at the JES Deinterlacer... it has some nice, elaborate slow-mo effect......

Slow motion effect

I was wondering how to get that slow motion effect that is so commonly used i music videos. I have a canon xha1 that shoots 60i and 50i. To achieve this effect do I do it all in FCP, or is a combination of having the fps high and then the sequence at 24. I could do it in FCP, but it doesn't look clean. If any body has anysuggestions, thankyou. peace. E.

Final Cut Pro can do slow motion with or without frame blending. In both instances you are creating duplicates of frames in order to create a slow motion effect. These look okay in video but with the effects you are talking about are done with large production values where the shots are done with slow mags where the film is running at a high rate of speed to get more frames in an action. There are cameras today that allow you to over and under crank footage but mainly they are tapeless formats where you are recording to hard drives, disks or cards.
you might want to investigate After Effects version 7 or later where it does time warping where individual pixels are blended rather than an entire frame like in Final Cut.

My slow motion effect won't work... HELP ME!!!

I really need some help here. The original version of Imovie that came with my OS X worked great when it came to adding the effect of slow motion with the little bar at the bottom. I just recently purchased the Ilife 05 package and was all excited to get editing... but now I can't get the slow motion effect to work at all. It does all the rendering of the clip but the effect does not appear in my time line!!! What is wrong??? Please help me!!!

Hey Karsten... I'm back again...
Yes you guessed correctly... but I never want to see another pc in my life. Now about my prob... I did as you said and still nada. I wish the upgraded version in the Ilife 05 package still had the slow motion control at the bottom of the main screen like in the prior version, but they have taken it off of the main screen and placed in the special effects folder as "fast/slow/reverse". and it is here that it slows the clip down in the preview and renders the clip with the red bar on the main time line. But the red bar on the bottom of the clip in the time line doesn't move and ofcourse the clip is not put in slow motion.
My brother is quite savy with Mac as well and he can't figure it out either. What do you think???

Is there a way to disable the slow animation effect when holding down the shift key?

Holding down shift at the same time with a shortcut (for example like Control + arrow for Mission Controll) makes the animation run with a slow motion effect. I would like to disable this setting as this collides with other keyboard shortcuts for some apps I've been using. I can't find this option in the keyboard section of the Preferences pane, and using the command 'defaults write com.apple.finder FXEnableSlowAnimation -bool NO' in the terminal doesn't work either. Is there a way to do this?

I tried the terminal command as well and didn't get it to work. Does anyknow how to do this now? I'm in ML.

Slow down effect won't work...

I recently upgraded to iMovie HD and when I try to use the slow down effect it renders it but it stays the same clip. Any suggestions on what is causing this?

You're not alone.
Unfortunately that's the only thing I can say and do for you...
Numerous posts deals with this bug. We can state that it appears in those cases:
- Ilife'05
- MiniDV film importation
This effect was so funny and usefull in previous versions of ilife.

Optical flow has bulged wave slow motion effect

Trying to slow down hd clips with optical flow, but it shows waving bulged effect, sometimes around the edge, sometimes the whole image. Using 2011 Mac book pro 2.3 g with 8 g memory and thunderbolt raid hard drive. No way to get smooth slow mo effect, any idea? Thanks.
Z.M

Thanks Tom, I uploaded a clip on youtube, it is a time lapse, actually, it doesn't matter what file, same bad effect. Don't remember in the old DV days time change is this difficult.
I chose time change, here 50%, then quality, chose optical flow.

Audio Problems with Fast/Slow/Reverse Effect in iMovie HD

I have been having problems with the Fast/Slow/Reverse effect in iMovie HD with my movie clips. Whenever I apply the effect (reversing at the same playback speed, not sped up or slowed down), when it is finished rendering the audio is choppy, yet on time (but still backwards, as wanted). Before applying the effect, the preview of it works flawlessly, it is only when it is applied that the audio gets choppy. Extracting the audio will not help either because the video will still be playing backwards while the audio will be playing normally (since it can't be reversed on its own). I have tried other effects on the same clips that don't effect the audio and they work perfectly. Any suggestions? I'd really appreciate your help! Thanks.
Macintosh Powerbook G4 Mac OS X (10.4.6) iLife '05 : iMovie HD

Have you got an isolated hard drive with ALL of the required applications and other resources together with the operating system ? Using an external HD to SAVE a running iMovie project is asking for problems. Back up the Project on another HD sure, but don't use System on one HD, running files on another.
Hope Helps,

How can slow-motion iphone6 video be exported to imovie on an iMac and retain its slow motion effect ?

how can slow-motion iphone6 video be exported to imovie on an iMac and retain its slow motion effect ?

thx, i can't see where you do that (access the function to slow the motion of a clip). in the help file it says to 'right click' on the clip to access those functions but when i do i get these optios below (no motion, pan, zoom, pan and zoom). i want access the speed/duration sliders.
i would say the function isn't available at all, but i could be looking in the wrong place (although i have tried everything).
thx for your reply.

Lp slowing down effect

Hi guys,
I want to recreate the LP slowing down effect, where tempo and pitch change at the same time, how do you do this on a prerecorded audio file?
thanks for your help!!!

you can always try Turntablist...it's a pretty cool effect
it's universal binary

How to properly timewarp 59.94 footage for slow motion effect for 29.97 output

I have footage filmed in 59.94 that I want to use for slow motion effects and output to 29.97. Using timewarp I seem to get duplicate frames at times. What would the best workflow to accomplish the cleanest result? I've tried interpreting the footage at 29.97 and keeping it at its native 59.94. At this point I feel like I'm just confusing myself further by just trying random things. Thanks!

Always interpret footage as what it really is. If it is really 59.94 progressive then that's what it should be interpreted as. It will play at the right speed in any comp of any frame rate. IOW, if the footage is 10 seconds and you put it in a 99fps comp and play it back at full frame rate the clip will still be 10 seconds long. If you put it in a comp that's 15 frames per second, the clip will still be 10 seconds long.
Make sure you understand that.
There is a chance, and a good chance, that your footage is actually full frame 59.94 fps video. That's why I suggested putting it in a comp that's also 59.94 fps and checking for duplicate frames.
There is also a chance that your footage is actually 29.97 fps interlaced. If you separate fields and look at the footage in a 59.94 fps comp you won't see any duplicate frames.
To change the speed of the clip you just need to apply Time Remapping, Time Warp, or any of the other Time Time tools in AE. It doesn't make any difference what the frame rate of the composition is, you'll be changing the length of the clip.
To keep from creating duplicate frames you either need software that interprets the new, extra frames or you need to use an exact whole number multiple of the frame rate for rendering.
Where did you get the footage? What Camera? What are you trying to do with it? What is the final destination (delivery) for your project.

How about using a 60fps video for a smooth slow motion effect in a 30fps project ?

Hey all,
I happen to have a video camera that is able to shoot either in 720p/60fps or 720p/30fps.
As you guessed it, 60 fps mode is very useful for action sports when you want to do some slow motion effect running very smoothly.
I have few questions I would love to be answered, and I was not able to find answers till now.
Here they are :
1/ If I want my final video file to be, let's say, 25 fps, is it mandatory that my project is 25 fps too ?
What will happen if I do a 30fps project and that I export to a 25fps file ? Does Premiere simply remove some extra frames ? Or will it lead to a longer video ? What consequence on the final result if frames are removed ? I mean, will I be able to see any difference or will the difference remain theorical ?
2/ Let's say I have both 30fps and 60fps videos. I set my project to 30fps. If I import my 60fps video to the timeline, it will be adjusted to 30fps and some frames disappear to keep the duration the same. Okay, this is clear to me.
But now, what if I import my 60fps to the timeline, but set the speed to 50% ? Will Premiere apply the 50% to the original file (therefore I should have all the frames displayed on the timeline : 60/2=30 fps), or to the 30fps-adjusted file of the timeline, leading to some jerky footage?
3/ If I want to use my 60fps for slow motion purpose in my 30fps project, would it be a good idea to right-click on this file in the project windows, going to the "modify" menu to set the image frequency to 30fps ?
Because while doing so, if I drag the file to the timeline, I noticed it would last 2 times longer (resulting in a slow motion video) Does that mean that ALL the frames of the original video are displayed ? Can someone tell me what exactly does Premiere ?
I would be very grateful if someone could tell me what are the correct settings to chose in order to realise the best slow motion videos as possible.
Thanks in advance !

With due respect... this does not answer my question and does not help me that much , but anyway, thank you for the very constructive answer ^^.
I'm not sure I would even have considered doing this by myself...
I hope I do not get this kind of answer because you feel like my question was silly or unpolite... To my mind this was a pretty serious question.
Shooternz, next time you need to go 150 km far away from where you are, go by feet rather than with a car, I'm sure you will have plenty of satisfaction too. Just cross the fingers for you not to be in a hurry while it's raining outside.
Well, I may be naive but i thought some experts already had the answer to this (I guess I'm not the only one who intend to do some slo mo), and would have been kind enough to share this knowledge with me. That's what sometimes happens in communities.
Please note I do not intend others to do the job for me, I'm just asking if someone already knows the answer.
I asked this question because I couldn't find any documentation about this, and I guess asking on internet was the next step, as testing would be like the last resort, being very time consuming.
It was easy to check the effect of dragging a file to the timeline to see if it played normally or not, but it's definitely not to count and compare each frame of some sample file to find if some are lacking, or have been doubled or what....
I assume I would be very happy with just a simple theorical answer either...
So once again, if someone already has been into such questions, I would really pleased him or her to share or report what they experienced. Thanks in advance.

Slow genie effect animation

80% of the times I log (being it by user switching or a clean boot) I get slow genie effect animations when minimizing. The animation doesn't look fluid... it looks like a slow frame by frame; and though the time from when I give the command and the complete animation ends is almost identical to the healthy performed animation (meaning it's more of an aesthetics issue rather than performance) it's still kind of annoying.
They only thing that seems to fix it is closing all windows and quitting the Finder (or force quitting if you haven't add the Quit option to the Finder with Tinker Tool or something like that). After that it works just fine... until I reboot or log off.
Any suggestions?
btw: I can't tell if the same happens on scale effect.

Found the answer; sorry. (well... kinda)

Sound vanishes with slow down-effect

When I use the slow down effect on a clip, the sound disappears. I have tried to extract the sound, but the problem remains. Is this supposed to happen with this effect?
Best regards

To simplify the question: Has anyone manage to keep the sound after using this effect?

Slow fade effect

Hi!
I'm using the following code to do a fade transition effect between two images:
     public void render(Graphics g, Image imageFrom, Image imageTo, int width, int height) {
          BufferedImage buffer=gc.createCompatibleImage(width,height);
          Graphics2D g2 = (Graphics2D)buffer.getGraphics();
          int counter=0;
          while (counter<90) {
               counter=counter+2;
               double alphaScalar = Math.sin(Math.toRadians(counter));
               g2.setComposite(AlphaComposite.SrcOver);
               g2.drawImage(imageFrom, 0, 0, null);
               g2.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, (float)alphaScalar));
               g2.drawImage(imageTo, 0, 0, null);
               g.drawImage(buffer, 0, 0, null);
               try {
                    Thread.sleep(5);
               catch(InterruptedException ex){}
          g.dispose();
          g2.dispose();
          buffer.flush();
     }My main problem is that using a buffer to save the image composite before drawing it over the panel's Graphic context slows the effect considerably. I have other effects (scrolling, sliding and some more) which don't require the use of an intermediate buffer and they are way faster without it. I'm looking for a way to improve the perfomance of my fade effect. I've tried to draw the image composite over the panel's Graphic context directly (no buffer) but the screen flickers. Can anyone help me, please ?
Regards
