Stuttering slow motion

Everytime I do a slow motion effect is stutters. Any ideas on how to smooth it out?

When you are adjusting the speed make sure that "Frame Blending" is selected.
If that doesn't cure it you could experiment with the Deinterlace and Flicker filters.

Slow motion looking bad

I have tried to slow a video clip down to 30% speed. It looks smooth when played back in FCE, but when exported to a QT movie, it becomes jerky with brief stuttering of frames.
I have tried the techniques described in other posts but nothing seems to work. First, I tried it with just frame blending. Then I superimposed a copy of the clip, and used the de-interlace/flicker filters without frame blending.
The original footage was shot on Super-8 film, transferred to DVD, and converted to DV.
Any suggestions as to how to make the slowed clip play smooth after exporting would be greatly appreciated.

Have you tried the Toltzman solution ? It works only for 50% slow down, but it seems to work better than the standard Speed command. Let me quote it from an old post:
"When you slow down a clip in FCP/FCE, the application does not use the 60 (or 50 in PAL) fields/second of interlaced video, which can help to achieve very smooth 50% speed video.
Here is a recipe for converting your 60/50 fields per second in to 60/50 frames per second for a nice, smooth slow motion effect at 50% speed.
Slow motion in FCE using both fields of Interlace video to get smoother slow motion at 50% (uses all 60 fields).
1) layer two copies of video in timeline over the top of each other.
2) apply a de-interlace (1) and blink (2) filter to the top copy and set the de-interlace to use the Upper field. Set the Blink filter to an on duration of 1 and an off duration of 1.
3) apply a de-interlace filter to the bottom copy and set it to Lower field.
4) Set the speed of each layer to 50% and turn OFF the frame blending.
The top layer and bottom layer should now be interleaved. The top layer will contain only the upper field (repeated across 2 frames) and the bottom layer will have the lower field (repeated across 2 frames). The Blink filter will switch back and forth between the layers to use all fields as frames.
If your field dominance is different than NTSC DV, then you'll have to reverse the de-interlace settings on each video layer
By Douglas Toltzman"
The result is that each single field (both upper and lower) is repeated twice, while with the standard Speed command only the upper field of each frame is repeated 4 times, and lower fields are discarded.

Poor quality slow motion

i have a montage of a wedding set to three minutes of music, all the slow motion video is choppy, when someone walks across the screen they appear to be stuttering. when viewed on the timeline the motion is smooth and just how i need it to be but when exported to apple intermidiate codec and burned via toast 9 the image is jittery, stuttering when we view it on our TV.
Desperate for answers as the finished production should be inthe hands of the bride & groom next week?

If this is a standard DVD, I think you'd be better off exporting a QuickTime movie from FCE and burning with iDVD. If you'll create the DVD on the same computer, leave the "self-contained" check box blank for a much smaller file and quicker process.

HVX200 slow motion ?

I shot 720PN at 60 frames per second with the Panasonic HVX200. I used FCP "Log and Transfer," and it created Quicktime files on my scratch disk just fine. When I play one of those files in the Quicktime player, it actually has 60 separate frames per second - I counted them. So far, so good.
But when I import that file into FCP (Sequence set at 720 P / 24 fps), it will not play as a slow motion shot. It plays at regular speed; I can see people walking around at normal speed.
I tried using Modify - Speed to reduce the clip to 40%, but that just duplicates frames and gives a stuttering look. I can't figure out how to get all 60 fps in Final Cut Pro. Anybody know what I'm doing wrong?
- Seth Hill

I set the camera to FILM CAM, then selected 60 fps in the first menu, then set the record setup to 720/24PN. I thought this would "overcrank" the shot.
Nope...that didn't do it. YOu set the camera up at 720p60 and the frame rate at 24fps. Then it records 60frames to 24 frames...thus slowing it down. Play with this setting...
But when I put the clip into the Timeline (Sequence settings are 720P / 24 fps), the clip does not play like slow-motion; it plays at regular speed.
Yup...because just dropping 60fps into a 24fps timeline does not slow it down.
If I use Modify - Speed to slow it down, it does not show all 60 frames, it just duplicates frames and creates a "stuttering" look instead of a smooth, slow look.
Correct...because that is NOT the way to slow down DVCPRO HD 60fps footage.
Is there a way to get the "overcranked" shot into FCP without having to convert it?
No. WHy are you against converting it? The FRC makes a new clip that is slow...so you have the main clip which is normal speed, and the new slow motion version. Why is that a problem?

Slow motion and frame rate and shutter speed

I have two cameras that record 60i and three that use 30p. Neither of the 60i cameras has a 30p option (one has a pf30). If I understand how FCPx handles this, if I drop both frame rates into a project, I get 30p out, correct? In effect de-interlacing the 60i footage to 30p. Is it best to import the 30p footage first to set that frame rate so that the 60i gets rendered to 30p?
We're producing a fishing DVD so good quality motion footage is important. This is an instructional DVD so I will be using some retiming to slow footage down to illustrate key points in the instruction.
I've read a lot of stuff on 1080i 60i vs. pf30 vs.30p vs. 24fps and benefits of using 720p vs. 1080i. Also looked at information on slow vs. fast shutter speeds.
So, the bottom line to get the best motion results for the DVD, I should be shooting at best bit rate possible, use 1080i 60i or 30p depending on the camera and let FCPx set everything to 30p. Correct?

For the 1080/60i media, it is best to have FCPX conform it to 30p (29.97p). [30p is a real timing: 30 exact frames per second, but it is not broadcast compliant. 29.97 is quite often simply referred to as 30, just for simplicity and/or laziness. The final decision for which to use rests with you. Also note, like "30 fps", 60 more often refers to 59.94 fps... for the same reasons.]
As for your target being DVD: DVD is always 480 lines whether it is anamorphic (16:9) or standard 4:3. If you would like to have "enhanced" slow motion, my recommendation would be to shoot in 720/60p (which is genuinely progressive "60" frames per second) and will give a slightly better edge on slow motion effects (retiming). That said, FCPX retiming is usually quite good no matter what the frame rate (frame blending recommended over optical flow [which tends to give a "morphing" effect when pushed too far].) 1280x720 frame size will give you plenty of downsampling resolution for DVD as well. [I *believe* that FCPX will use all of the 60fps available from the original video in retiming, even if the frame rate of the project is slower than the original media; so, 720/60p conformed to a 30p project and retimed to 50% will use every frame of the 60p slowed down by half... (somebody correct me if I'm wrong!)]
Best bitrate is also an important feature, but that is not due to the choice of format as much as that provided by the camera itself. Bitrates out of the camera may be relative to the frame size (they are in my consumer camcorders). A common consumer grade camcorder will top out at a bitrate (for 1080) somewhere between 17.5 and 22.5 Mbps, whereas an HD capable DSLR will usually top out at (easily) *twice* as much (45Mbps average from my Canon T4i) or more. Furthermore, the DVD standard imposes framerate restrictions (max is somewhere between 5 and 8Mbps -- the software that creates your DVDs will usually transcode for best bitrate, so not something you really need to bother with - just set the transcoder to best possible quality and provide it with the best quality video that's reasonable.) Whichever camera provides the highest bitrate should be your "main" camera.
As you may have discovered: another factor for a quality video regardless of camera is shutter speed. If you set the shutter speed too high (faster than twice the frame rate) then you will have "stuttering" issues (there will be "gaps" from still frame to still frame). Keep the shutter speed at the same or no more than twice the frame rate: e.g., for 1080/30p (target) the shutter speed should never be more than 1/60th of a second (I'll use 1/30th, 1/40th, or 1/50th usually). I haven't shot a lot of 720/60p, but I think I would still keep the shutter speed at between 1/60th and 1/120th exclusively [that is -- I wouldn't go as high as 1/120th or greater... but that's me... you should experiment for best results for you. If this creates exposure issues, then consider neutral density filters or circular polarizing filters to help bring scenes into exposure range (via aperture or iso or both.)

Good luck! Have a good shoot!

Slow motion lost after sync from mac to iphone

Hi,
I can capture videos in slow motion but those videos play at normal speed once Sync them via iTunes.
1. Capture videos in slow motion.
2. The videos first play in slow motion in the iPhone. There is a time line slider to move the slo-mo effect back and forth.
3. I do a back-up via iTunes including videos.
4. After syncing, the videos in the iPhone appear in one album called "Slo-Mo".
5. In the thumbnail of the video clip I can see the small dial icon that all other slow motion videos have.
6. Playing the video shows a normal speed clip without the timeline slider under the video frames view.
The videos DO retain the slo-mo "effect" in Aperture and iPhoto also. Not in the iPhone after syncing.
Any hints to solve this? thanks

iPhone 6 iOS8

Hi,
iOS 8.1 didn't fix the issue so here is my workaround to " show-off " my slow motion clips:
I have tried to open the clips with iMovie in the iPhone. ( I guess not everyone has iMovie installed...?)
So, you can create a new project in iOS iMovie and import the clip you want. Slow motion clips preserve the little dial icon so you can see which ones have the slo-mo effect. It will preserve the slow-motion sections of the original clip and will play "slow".
If for some magical reason your clip doesn't play "slow" in iOS iMovie click on the small "tachometer" icon and select the desired speed.
So. iMovie does know the clip has enough frames to play in slow motion... why the camera app doesn't ?
good luck,
jp

Slow motion on windows xp pro

Hello,
I'm on windows xp pro by boot camp and I have sometimes some slow motion. It's a problem when i'm listening music. I didn't find virus with avast antivirus and my computer used to be clean with Ccleaner and Spybot search and destroy.
What can i do?

I would post in the Boot Camp forum area here:

IPhone 6 Plus IOS v8.1 Slow Motion BROKEN

Film in either of the two slow motion speeds and plays back ok on phone. I put the files in the computer (grab the raw file via explorer), on Win 7 Professional, and played with both windows media player AND Quicktime player (up to date players) and the videos play either no slow motion, plays alternating between fast and slow, one time it played slow but had normal voice pitch, other times played slow with low voice pitch. On youtube, they don't play in slow motion. One I shot vertically (which I did just as a test) and it was sideways in the computer, however, youtube rotated it so it's vertical but it is not in HD and it does not play back in slow motion. This same file that was sideways in my computer stopped playing after about 2 seconds in the computer, but played through ok in the phone. I noticed that as the video plays in the phone, there are blue vertical lines below the left/right scrub/scroll bar for the video. This can be set to play only a portion in slow motion. But WHY does it start each video with the ends nudged in so the first 3 sec is regular speed and the last 2 are also reg speed also w/the slo-mo in between? It defaults to this each time an you have to spread it out to get all slow motion..
In Win XP, some of the video files don't show up. It shows .aae files with corresponding numbers to the videos, but most of the videos are not there.
I think this is a huge software bug that needs to be tested. I updated the os on my new phone before I put anything into my phone. Everything else has been perfect till this. HELP!

You said, "...plays back ok on phone." That's where Apple's software stops. Your problems with Win 7, Win XP, Quicktime, and YouTube need to be addressed on forums for those programs and/or sites. Presumably the issue has already been resolved by users on those sites, with different solutions for each.

Slow motion / fast motion in Premiere Elements 13

I read that in Premiere Elements 13 fast motion (and I think also slow motion) ist removed. Is that correct. And if yes: Is there any workaround available?

rr
Thanks for the reply.
Great information. If you have been using Ctrl+R, that is the keyboard shortcut that brings up the Time Stretch dialog.
Time Stretch (use of the Ctrl+R) has not been removed from Premiere Elements 13 Expert workspace.
Like Premiere Elements 11, Time Stretch is found in the Expert workspace and not in the Quick workspace.
When you use the keyboard shortcut Ctrl+R, I get Time Stretch dialog from where I can create the slow or fast motion effect in the selected clip.
The following relates to Premiere Elements Timelapse Capture (Stop Motion) which has been removed from
Premiere Elements 13 as a specific feature that you see in Premiere Elements 11 and 12.
Adobe Premiere Elements 11 * Capture stop-motion and time-lapse video
Please let me know if you are OK with the above information.
Thank you.

SAP B1 Patch 42 GUI, Vista SLOW MOTION

Hi,
I just don't know if I'm alone with this.
I didn't find any thread about it.
I've successfuly installed SAP B1 2005A SP001, Patch 42 on Windows Vista Home Premium. Everything works find
Except
When windows pop, its slow like hell. You know this animation when you open let say Sales Invoice window.
Well in Vista, it takes at least 10 seconds like if everything was in slow motion. But when the window is there, everything still works as normal !
Any idea ? Any patch ? Anything ?
Thank you

Hi,
Nice link but I'm not on version 10 but 42 and there's no error and no problem. Just the GUI is slow.
I don't think Vista is to blame but rather the poor SAP GUI which really need a fix since a LONG LONG time
that would also probably fix the problem of .NET WinForms not sitting on top when called from SAP
I'm more looking if someone knows something about it, a patch for the GUI or even a registry key that would disable the SAP window animation.

How can I flip my iphone videos on my PC? My videos from my iphone are horrible when I transfer them to my PC. How can I improve the video on my PC? Can I just convert the files to WMV? When the video plays the speed is off, it's half slow-motion

My videos from my iphone are horrible when I transfer them to my PC. How can I improve the video on my PC? Can I just convert the files to WMV? When the video plays the speed is off, it's half slow-motion and staggers into normal play. The clips are slightly cut as well, the clips do not roll continuously. I'm taling about videos that are no more than 2 minutes long. I'm frustrated and I could really use some advice-my kids basketball games is what I'm recording and I'm trying to send them to my family (they are not very tech savvy). Thanks

Not it's only function but one for which it was most admirably suited, which is why I really hope someone can find a work around. I am hoping my post to the Apple feedback may prompt a useful response from Apple and I live in hope that my post here will elicit a useful response from another user. I did not miss the the text at the top of the feedback form but you presumably missed my initial text, 'someone here can explain' or my subsequent 'work around from another user'
Just in case anyone reading this has a large collection of music videos, video podcasts or iTunes U then DO NOT upgrade your iPad to iOS 5. If you are considering purchasing the iPad as a useful mobile device to experience these media organised in your iTunes please don't as you will be wasting your money. (unless someone on this forum knows of a way to undo the mess created by those infallible folks at Apple)
Yes I know it does other things but the purpose I bought it for doesn't work anymore

Quicktime plays video in slow motion

Quicktime plays my video from a Sony NEX-3 camera [H.264 MP4 files] in slow motion. The images plays at a reduced speed, while the sound plays at full speed. One consequence is that image and sound is completely out of sync. The video plays fine in iMovie and MPEG stream clip.
I tried in two Macs: a Macbook Air (10.6.6) and a Macbook (10.6.5) and on both the video is slow motion, but on the Macbook it is extreme slow motion, while on the Macbook Air it is slight slow motion [mainly noticeable through lack of sync between image and sound].
Video from iPhone 4 plays without problems in Quicktime.
Since iMovie plays the Sony video fine, I would assume it is not a Sony video problem, but a bug in Quicktime. How do I get Apple to fix that bug?

Help! Movies from iPhone 5 play in slow motion when opened in Quicktime on PC

Hi there,
I was hoping someone may have the answer or have encountered this problem as well, as I have been unable to find anything on it elsewhere on the net.
I have transferred some movies, taken on my iPhone 5, to my PC. However when they are opened in Quicktime (as recommended) they play in slow motion.
However, the sound still plays at normal speed.
I have already tried going into the QT settings where you can speed up the playback, but this doesn't work either, no matter how fast I set it to - they still play super slow.
Although they are taking up heaps of space, I am worried to delete the movies off the iPhone in case they have not copied over properly and I lose the originals!
Any suggestions?
Many thanks!

Hi Matthias, thanks for your response!
We are running on Windows XP, is that what you mean? I will try and download the VLC player and see what happens. Are iPhone 5 movies higher res than iPhone 4, as we can play those?
If it is the system, do you know whether or not if I save the movies to our PC, then transfer than to another computer, should they play ok? I just don't want to delete them off my phone and have them permanently slow, iykwim?
Sorry if my ignorance is showing - I'm not overly tech savvy when it comes to this stuff!
Many thanks again!

HT4437 slow motion video to TV

I have problems transmiting a video with slowe motion from my iphone 5s to my TV through apple tv. I just hear the sound. Do not see image. Any idea???

Hi. After after trying too upload from the Facebook app, I found out that the video isn´t saved as a finished video. (you can still edit it)
I used the iMovie app to save the movie as new finished movie. Open iMovie , those video, select your video, click the share button i down right corner. Push create movie (I guess, mine is in danish) play the movie or not, push the back button, change the name or not, push the share button, save the the movie. Now you have a finished movie, that can be shared as any normal movie.
Hope this helps
Maybe there are other ways I don't know

I bought a movie on iTunes but when I try to watch it plays back slowly with no sound. Then the video will speed up and the sound will work for a moment then off again and back to slow motion. I have a dell laptop running windows 7
