Smoothing slow motion

Hi everyone. I'm using fcp7 and I do skateboarding videography. I'm using a Sony PD170 at 29 frames per sec. When I add a slow motion to a clip it doesn't look really clear, I'm slowing it down 65%. Is there an effect or something that I can add to it to make it smoother? Thanks for your help.

We see this post from-- interestingly, skate auteurs-- often so there is some searching you can do to discover past threads.
The issue is probably your shutter speed, not the number of framesper seconds. The 170 can only shoot NTSC at 29.97fps. Fast action requires more frames per second to allow more descreet slices to spread out. But if you were shooting at the default shutter of 1/60th second, your skater has moved a great distance while the shutter is open creating image/motion blur that cannot be removed.
If you were shooting at, say, 1/250 or 1/2,000th second, your individual frames would be crisp and you might be able to separate the fields out from the frames for twice the number of discreet slices of time at the cost of the loss of half the vertical resolution resolution, only half of the horizontal lines would be available in each field.

Smooth Slow Motion from 50 fps Clip in 50 fps Timeline

If I want 50% smooth slow motion from a 50 FPS video clip, I would normally ask PP to interpret that clip as 25 FPS - that works great.
If however I import the 50 FPS video clip and interprett it as 50 FPS, I would have to set the speed of the video clip in the timeline to 50% to get the same level of slow motion.
The question is - when I follow the latter method, does PP create new frames for the slow motion or is it clever enough to use all the frames from the original 50 FPS video clip? to put it another away, does PP always generate NEW frames for slow motion or does it try to use the frames we are attempting to ignore?
I've done some basic tests and so far I can't see any real difference between the two methods. This leads me to beleive PP is effectively using all of the original 50 frames when the 50 fps video clip is imported into a 50 fps timeline and then slowed down in the timeline by 50%. - if this is the case, well done PP!!! If this is not the case, then it would be a welcomed enhancement in future releases.
I guess what you are all wondering is why would I want to import a 50 fps video clip into a 50 fps timeline and then slow it down in the timeline - well, as a wedding Videographer, it is simply because some parts of the video need to be in slow motion and other parts like messages and speeches need to be interpreted at normal speed. If playback in the timeline is at normal speed, i find it simpler to slow down the "Walking Down the Isle" clips rather than having to speed up the speeaches and messages.
In short, when importing 50 fps video for smooth slow motion, are both the following methods equally effective in terms of smooth motion?
Method 1: Import the 50 fps video clip into 25 fps timeline
Method 2: import the 50 fps video clip into 50 fps timeline and set the speed of the video clip in the timeline to 50% - I'm assuming PP does not generate new frames and gets them from the original 50 fps file instead..
To put it another way, does PP ALWAYS attempt to generate new fromes when slowing down video in the timeline? When extra frames are available in the original video file, does PP try to get the extra frames from that file instead of generating new ones?

I recorded 2 video clips of the same scene. The camera was panning from right to left.
First video clip - recorded at 25 fps
second video clip - recorded at 50 fps
Both video clips recorded at the same panning speed of the same scene.
1. If I import the 25 fps video into 25 fps timeline and slow it down by 50%, the exported video looks jerky.
2. If I import the 50 fps video clip into 25 fps timeline, the exported video looks smooth motion.
3. If I import the 50 fps video clip into 50 fps timeline, slow it down in the timeline by 50%, and export the video as 25 fps then the result is still smooth motion.
I've only done the experiment once and may have to repeat to be absolutely sure.

How do you create a smooth slow motion

Attached are both the original clip, 2 second long, and 5 times slower clip of the original.
for some reason the slow motion is not smooth. is there a way to make it smooth?
thanks
arikw

If your camcorder can shoot 60p, import that clip, then right-click it and Modify > Interpret. The frame rate should show up as 59.94, go ahead and change that to 29.97 and then put the clip on the timeline. This should have the result of doubling the length of the clip and providing silky smooth 50% slow motion (without adding Speed Change, leave that at 100%).
Just picked up a new GoPro Hero 3 White, and it has 720p60 and I tried the above and it looks nice! The more expensive GoPros offer 720p120 and that should yield excellent 25% slow motion using the same methods. With the waterproof housing and wide angle lens, you could get right up close to that waterfall!
Thanks

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.

Smooth Slow Motion

I am looking for a way to create 50 percent slow motion based on odd and even fields. Instead of replicating the odd or even field to make a 15 frames per second, jittery, slow motion, I want to separate the odd and even field, and then interpolate the missing half frame, thus producing a 30 frame per second smooth motion clip that is based on the 60 half frames per second frame rate of video. I know this can be done because Premiere does it automatically. Note: I am not trying to make smooth motion where there is a half translucent image of the preceding frame always on top of the current frame.

Okay, I think Graeme Nattress wrote a plugin to do that, but here's a way to do it in FCP...
Cut your clip on V1 and V2, slow each down 50% with no frame blending. On each clip put the de-interlace filter, on V1 take it from field 1, on V2 take it from field 2. Now apply the blink filter and set it for 1 frame on and 1 frame off. This way it will take first one frame from V1, then one from V2, etc...
Mind you this is a lot of monkey motion, but it should give you the effect you are looking for.
Try it, post back...

Smooth Slow motion - THIS IS HOW !

Just thought i'd throw this in to try and give back a little to these boards.
I have seen slo motion come up quite a bit .
I work with alot of action footage and beat match soundtracks so speed changes are important to me!
I work in DV PAL - this should still work for NTSC!
Change the speed of your clip in FC via any one of the 3 methods that are available.
Anything below 50%starts to look choppy on the standard settings
Double click on the clip - go to the viewer -that now references the clip to be retimed - click on motion tab - go to motion blur and check the box
Here is the trick - set motion blur to ZERO and resample 16 or 32 times
render away.
voila !- pretty good smooth slo mo that can get down to as low as 20% and still look pretty good!

Oh James you beat me to the response.
I just tried the OPs technique on a wide shot of a baseball double play @ 40% slowmo. It looks much better than the choppy slo mo that I would have had to settle with. I purposely chose a wide shot because I wanted to see if the blur would make a distracting visual difference. It does of course on a wide shot, (at least for my eye) but I bet on medium and clos-ups it's a true gem.
Thanks Oz for the post

IPhone 6 240fps slow-motion import

Hey everyone,
I understand when I import the clip into Final Cut Pro I choose 30fps, and then click on the clip and set it to automatic speed. Then I will get my 240fps slow-motion.
2 issues though.
I would like to have the same effect as Quicktime Player opens the file for me. Starts in normal speed and then transfers to the slow-motion. I could probably build this with speed ramp, but is there an easier way to just have it like that already?
Second issue, when I set it to automatic speed, I do not get the sound from it. In final cut pro x it sounds really weird then, just very high sounds (rain), but in Quicktime Player and on my iPhone I really hear the deep sound when the raindrop hits the ground. Any idea how to transfer that sound or how to get it?
Probably needs an upcoming update FCPX?
Edit: Now when I would like to export in QTP to YouTube I do not get the slow-motion either, it's just like that: https://www.youtube.com/watch?v=xkk1DfTcgn0

There is a misconception about the "slow motion videos" in iPhone.
In fact, they *really* are videos recorded with a high frame rate (up to 240fps in iPhone 6).
They are *not* in slow motion per se - even though the iPhone software may play them as such.
In fact, I'll go so far as to say that there is no such thing as slow motion videos. There are videos played in slow motion.
What happens when, say, you drop your 240fps video in a 24fps timeline, is that it plays at normal speed. This is as it should be!
The big deal is that, since your clip has all those extra frames in it, you can use FCP X to slow it down (up to 1/10 the original speed in my example) and it will use all the real frames the camera captured. Plus, you can use all the retiming features in FCP X to obtain perfectly smooth slow motion.
By means of comparison, if you slow down a video recorded at the same frame rate as the project it is in, FCP X has to make up extra frames that did not exist. Even though FCP X has some great algorithms for this (like "Optical Flow"), it can't match real captured frames.

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.

Slow Motion with Full HD footage

Can anyone help?
I am using full HD footage 1080p 25fps, and when I slow the footage down It gives me the shutter look, not smooth slow motion!
Luke

Try Frame Blending and also try different percentages... example...35%, 45%, 50%
Depending on what shutter speed you were shooting can make a difference.
For best 50% slow motion you can shoot with a Shutter of 120. (If working with 60i)

Tried to shoot 60 FPS for slow motion, but ...

I have a DVCPro HD clip, 720P, 59.94 frames per second. I was hoping to get a medium slow-motion effect in FCP. So I imported it and put it in a 23.97 frames per second sequence. It shows at regular speed. Hmmm...
I looked at the clip in the Viewer. I found a part of the action that lasts one second, and I counted 60 frames for that second. But in the Sequence, that same action shows only 24 frames.
Then I got a brilliant idea! I used Modify - Speed to slow it down to 40%. I hoped I would see all 60 frames of that one-second bit of action. But instead of showing all 60 frames, FCP uses only about 24 frames, and copies each frame once or twice to stretch out the action. So the action looks jumpy instead of smooth.
A friend last last month shot something with the Panasonic HVX200 at DVCProHD 59.54 FPS, and he got a smooth slow motion effect in FCP. But he moved out and isn't answering his phone.
Any suggestions would be greatly appreciated!

I owe everyone an apology, because I gave the wrong information about the video file. As you will recall, I was frustrated that it appeared to play at only 23.97 frames per second in Final Cut Pro, even though I thought I had shot it at 60 fps. Yesterday I discovered why it appeared to play at a different frame rate, but the reason was so bizarre, so unbelievable, that I began to doubt my own sanity.
Friends, the video clip changes frame rate in the middle! Yes, it does. You see, I had been looking at a portion of the shot with the lower frame rate; later in the same shot, the frame rate increased to 60 fps. You may ask, how is this possible? I do not know. I only know that I shot it with the little Sanyo HD1000 camcorder, which records as AVCHD (h.264), and the clip changed to a slower frame rate when the shot got darker, then back to 60 fps when the shot got brighter. Apparently the camcorder reacted to the lack of light by decreasing the frame rate, in order to have time to gather more light for each frame.

Can Slow Motion Be Done in FCE?

I have a video file that was shot in 720p60 (1280*720p @ 60FPS). I was hopping to be able to slow down this clip to 50% of its actual speed and get that nice slow motion effect. I shot it in 60FPS so that I would not get the choppy look of 30FPS when you slow it down. However, from what I can tell, FCE does not do a very good job of handling 60FPS footage. So my questions is, did I overlook something, or am I going to have to fine an other program to do this with?

Would I not still get the same choppy quality you usually get when slowing 30FPS down to 50%. I was wanting the completely smooth slow motion like you see in professional productions. Correct me if I am wrong, but wouldn't you get the 50% slow motion effect just from playing a 60FPS file at 30FPS?

Best workflow for slow motion from Canon 7D?

Hey guys,
I am working with a slow motion clip for the first time and I am realizing that there isn't really an easy workflow with this. First of all, the clip was filmed with the Canon 7D, 60 fps. When I put in on the timeline, obviously I get rid of the audio. But then if I slow it down to 50% I get the typical frame blending crappy looking image that FCP gives me EVEN THOUGH the sequence settings are set to playing 30fps. In reality, I thought that when I import the clip in the timeline with those settings the clip would automatically be double-length... Stupid me. It's treating the clip like a normal regular clip and so when I slow it down it does the same thing it does with all clips - a terrible job at slow motion. So basically, at 50% it should be playing every frame and there should be no frame blending but apparently that's not the case.
So.. What's the best way to work with this? I tried putting the clip on a separate sequence and then slowing it down which did a much better job but then I had to export the clip out of FCP and bring it back in as a "new slow motion" clip if I wanted to preserve the effect. What happens if I have more than one clip? Is there a way to do "batch export" on all of them at once and not just one clip at a time? What's the fastest and best way to work with a 60fps clip in FCP and mix it in with the rest of my clips which are 30fps without it looking like crap?
I also just found out about Optical Flow in Motion and that's great but wow... the render time is many many hours for a 5 minute clip... that's crazy. I don't have that kind of time.
So... Please help! Thanks guys!

Step 1: Convert to ProRes. Log and Transfer, MPEG STREAMCLIP, Magic Bullet Grinder...whatever. Make it ProRes.
Step 2: Duplicate the clip if you want to also have it normal speed, because Step 3 is not undoable.
Step 3: Take into Cinema Tools and CONFORM to the frame rate you want. 29.97, 23.98...whatever the rest of the project is. This conform is permanent. It takes seconds, but is undoable. Thus what you did in Step 2.

How to make smooth slow-mo?

I cannot for the life of me figure out how to slow down clips?
Currently, I am working in iMovie, and when I slow down the clips, they are really jumpy, even though I shot them at 720p 60fps.
I can't even find out how to slow clips down in Final Cut Pro X. Once I've done that, how to make them play in SMOOTH slow motion?
Thanks!

Hi fox_m,
i'm a huge fan of your advices on Motion5 - learning everyday, appreciate your efforts here on the board!
a) doing tons of sports-videos for my lil' football kickers, I'm for years desperately in search for the 'ESPN-like' super slowmo - on a shoestring budget, a Phantom-cam is no option
what I noticed with OF in FCPX - it does a wonderful job, under certain circumstances (made a test, click here): this is 60p in a 25p project:
it becomes obvious - rotation is poison (notice the ball in foreground) and too high angle-speed doesn't perform too (compare legs of player in foreground vs. players in background)
recording from a tripod, 'far away' or action straight in axis of cam plus short shutter speed gives good results - and are mostly the ones shown with Twixtor!
Had the priviledge, playing around with it for 20min on a friends Mac (AE as host) - I was completely lost in its zillions of options - I do understand the concept to tell Twixtor 'background' and 'object', but the interface was way beyond my horizon ...
b) Next Neighbor? Wot? Did I miss something? 'new' to me, will test today immediately! thanks for input!

10000 FPS Slow Motion Questions

I am shooting at 10000 fps using the Sony HVR-V1U. I am attempting to achieve a smooth slow motion shot. Final cut shows the footage as being very jerky and blurry. Does Final Cut support high fps and if so how do I import it properly so that I can either slow down the footage to play back smoothly or change the playback speed in Final Cut?
Thanks

Uh...that camera cannot shoot 10000fps. The max it can shoot is 30fps. The SHUTTER can be switched to 1000 (but not 10,000 I don't think), but that is not the FRAME RATE, it is the SHUTTER speed. Two very different things.
Final cut shows the footage as being very jerky and blurry.
That is what a high shutter rate tends to do.
Does Final Cut support high fps
Not 10,000fps. Not that it matters, you didn't shoot 10,000fps.

Using 720p 50fps video for Slow Motion

Hi there,
I've recently started using Photoshop Elements 9 for editing my action sports footage, and its a big improvement over free to use programs that I used before.
The thing that I have run into, and that I can't seem to solve, is making footage slow down.
I'm using both a GoPro camera (HD and HD2) and a Canon EOS 550D to shoot my video. Everything is shot at 720p @ 50fps so that I can use the footage slowed down when I want to use it that way without making it choppy (in normal 25fps export video (can be 720p, but I might use 1080p as well))
I've set up a project in PE9 using the preset for PAL-DSLR-720-50fps so that (me thinking) I can import 50fps footage without losing frames for importing. However, when I use the time timestretch function (through right click menu) and set the strech to 50% (so effectively 25fps) the video doesn't appear to have the extra frames. Even after rendering, if I foreward 1 frame at the time, every second frame is simply just a copy of the previous one. I've checked the file properties through PE9 and it says that the file is 50.000fps, so there should be 50fps available to build the footage from (yet only showing 25fps in frame by frame mode).
In searching the forum I've found some other suggestions to solve this, including the 'Interpret Footage' function. I've tried setting it to 'Interpret as 25fps' to see if this changed anything (as to smear out all available 50 frames over a 25fps clip, doubling its length), but that also retured with a copied frame every second frame.
I've also tried setting the project preset to DSLR-1080p @ 25fps to see if that might have an effect, but as soon as I import my 720p video it changes the project preset to AVCHD-LITE-720p50. Using that returns the same issue (btw, what is the difference between DSLR setting and AVCHD?). Using the AVCHD-720p @ 25pfs together with 'interpret footage at 25fps' also reverted to 50fps as soon as I imported the video file.
Frame blending isn't an option as it doesn't actually blend them. It just overlays the two frames and changes the opacity of the upper one (or so it seems), creating this weird blurry overlay effect, instead of interpolating the objects between the two frames (but maybe I'm asking for too much on this function).
Can someone please help me solve this slo-motion effect issue? I really want to use the full available 50fps footage I have shot to create smooth slow-motion in a 25fps export video (i'm not looking at reducing it much more than that). It seems that half the frames are dropped out as soon as I import into PE9.
Thanks,

As we've often discussed on this forum, Go-Pro footage rarely behaves in this program as source footage. The best solution we've found is a conversion to an editable format.
http://forums.adobe.com/thread/668369?tstart=0
In fact, mixing video footage of any types is usually not a good idea. Especially when your project settings may not fully match either.
Try using just the footage from your Canon. When you add it to your timeline, do you see red lines above the clips? If so, you are not using the correct project settings for your footage.
