Different slow motion methods

Hi there,
There seems to be a variety of ways to slow down footage in Premiere Pro. I am using a GoPro Hero2 shooting footage at 720p using 60fps.
I am wondering what the *best* way of slowing down the footage is and if there are large advantages or disadvantages to each method. Here is what I know I can do.
1. Create a new sequence of a lower frame rate and drop my original file in there and insert this new sequence back into my main sequence.
2. Right click on the clip that I have inserted into my main sequence at 60fps and click "Show clip keyframes > Time Remapping > speed" and then drag down the bar on the clip to be of a lower percentage, thus slowing down the footage.
3. Use the rate stretch tool (although it does not seem to change the time remap bar that is seen on the clip - that remains at 100% even though the clip plays at a slower pace after using the rate stretch tool).
4. Right click the clip that is in my sequence and select "Speed/Duration" - Edit the speed to be a lower percentage of its original speed.
Can anyone tell me what the best way is to slow down footage, or indeed what the advantages or disadvantages of each method are?
Thank you in advance!
John

So my main sequence is already a 60fps sequence. All of my footage is 60fps. Should I have created a 30fps sequence? I like to show down a lot mf my footage even to 80% so I keep my sequence in 60fps.
So if my sequence is 60fps and my footage is 60fps, do I still need to interpret the footage back to 30fps? Why can I not just do a "Speed/Duration" change? This is what I have been doing so far but I hear a lot of people talking about interpreting footage and doing time-remapping etc. I just dont know what advantages that gives me over "Speed/Duration" changes if my sequence is 60fps and footage is also 60fps.

What is the suggested frame rate to record in for fast / slow motion processing from a clip recorded

I want to create a video however I only have 1 dslr camera and I want the ability to post process the clips I record to be either in slow motion or fast motion. I don't want to have to record something in 24fps then 60fps. is there an ideal frame rate for both. What are some of the best practices for this in regards to recording and post processing in Premiere Pro.
Example of fast and slow video. Thanks.
http://vimeo.com/75259949

The ideal is to shoot in different frame rates, one for real time footage and one for fast or slow motion clips. This is called under and overcranking. It means you have to decide when shooting whether the clip will be real time or not.
Less than ideal is to shoot everything at one frame rate and then slow it down or speed it up later. It's less than ideal because the effect is never as perfect as the ideal method. Especially in PP, which does not do very well with slow motion to the point I recommend using After Effects instead. (At least with 24 fps media.)
On a side note, you can help solve the horrible slow-motion problem:

How to best achieve slow motion and fast motion

Hi - I am new to the forum and a basic user of Premiere Pro CS5. I am working on a project shot at 24 fps, and would like to do slow and fast motion.
From what i understand there are 2-3 different ways to do this in Premiere - choosing speed/duration of the clip from timeline, or choosing time remapping form effects panel ot using rate stretch tool. Wondering how do these compare and which is better - any pointers for this will be great help. Also is slow motion and fast motion better done in After Effects than Premiere. Or any recommended plugins that would work on cs5 and cs5.5. Thanks.

The main difference between using time-remapping and just using time-stretching is that time-remapping allows you to change the speed quite flexibly at different times in the same clip, whereas stretching just changes the rate for the whole clip.
See this page:
"Change speed and duration for one or more clips"
> Also is slow motion and fast motion better done in After Effects than Premiere.
After Effects has far more control, especially with regard to how new image information is created between the original frames when you change speed and require frame interpolation (frame blending). Pixel Motion and Timewarp use a very advanced motion vector method (based on the Foundry's Kronos software) for doing this.
See "Time-stretching and time-remapping".

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.

Is it possible to play back an After Effects composition in slow motion? (CS6)

Hi,
I'd like to play back the composition in slow motion so I can make sure the animations are smooth.
I find that sometimes you see gaps in your animation when you play it back frame by frame but you only just notice that something might be off when you play the timeline back in real time. So this would be for "proofing" your footage. I find the frame by frame approach a bit tedious for a lengthy composition.
Is this possible?
Thanks

You can enforce a different framerate on the Preview palette.

I have a video that is 1920 x 1080 14.99fps, when I load in Premiere 1080p30 it appears to be moving in slow motion, How do I fix that?

I have a video that is 1920 x 1080 14.99fps, when I load in Premiere 1080p30 it appears to be moving in slow motion, How do I fix that?

I am having the same problem, which I can explain a little better: A clip which is actually 29.97 fps (verified using QT properties) is importing as 1/2 framerate, or 14.985 (rounded up to 14.99) fps. This happens with several of my clips, regardless of the import method used (drag/drop from OS, right-click/import, or use Media Browser). I cannot interpret the footage back to 29.97, as doing so doubles the speed of the audio (an interview) making it unusable.

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)

Time remapping / slow motion extremely jumpy with nested sequence!

I have just finished the rough-cut of a ceremony when I went back to add effects-- slow motion, color correct, etc. only to find that ANY time-change is jittery-- extremely jittery, like it's skipping frames.
For trial purposes I created a new timeline with only one video clip placed multiple times. I reduced one to 50% with frame-blending, the other 50% with NO frame-blending and the final using time re-mapping with frame-blending. At 50% I don't expect fluid movement, but they are all acceptable... Until I put a different timeline in the timeline (I think it's a "nested sequence").
When speed is slowed on ANY nested sequence it is jittery. Whether it is a single nested sequence or a multi-camera sequence, it jumps.
Has anyone else had this problem?! Is this a bug? I never noticed it until this wedding. I am using CS3 and I cannot afford the time to re-edit this ceremony with 2.0.... Unless I have no choice.

Hi Wil,
I have tried using both. Time remapping on the clip (not nested) works fine, so does 'speed change.' But both time remapping and speed change result in jumpy frames when applied to a nested sequenced clip.
I tried this on another (much lower system) and have found the same results. I am begining to think it is the footage but it seems odd that it is perfect when applied to a clip in the timeline but NOT to a timeline in the timeline (nested).
I am on vacation and do not have access to a faster machine until next late next week but for now I will try the export again to be sure Encore sees the same thing.
I am dumbfounded because I had been using 1.5, then 2.0 and now CS3 for weddings for years and have never noticed this. I have noticed it on the both the last project and now this current one.
I thought it could have been the original footage (or a camera problem except that the problems are not there until a nested sequence comes along. I will try moving the footage to my internal drive now and see what happens...
Thank you so far for giving me ideas.

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.

Strange "strobe" effect when doing slow motion

hi
after using fcp for a year now, i strangly encountered a problem in a video i need to deliver in 2 days.
whenever i did a 50% slow motion i get a strange "strobe" effect. when the frame is more or less static then you wont be able to see it but when the camera pans or the object in the frame moves it is very disturbing.
this is only noticable when viewed on a tv set, not on my display.
i thought it was in the encoding so i did the whole "export using QT" again, this time making sure its 2 pass VBR 6.8 to 8 mbps. still there.
i am working on a Pal system without a monitor so i burned the video onto a dvd using dvdsp (as usual) and then played it in a pal dvd player and tv but this strobe thing is still there.
b.t.w the interlace option on the "export using QT" was set as auto, the same as always.
i didnt do anything different this time but still i get that problem. what could it be ? all the settings in fcp settings are set to 100% quality and the video is fully rendered.
i appriciate your comments and help.
thanx
nir evron

hi jim and thanx for the quick reply...
i used to do my slo-mo in fcp without any problems till today.
b.t.w - im editing DV PAL.
i dont have motion so i'm stuck to fcp.
any suggestions ?
thanx

Slow Motion on Multiple Clips

Ok so I'm newish to Premier and starting to get frustrated by how slow it is to edit in this software. Surely there must be an easy way to make a whole sequence of clips run in slow motion at 50% speed. I've copied down the clips to the timeline but it seems I have to time remap on a clip by clip basis and moreover there's no easy way to stretch the new longer clip in the timeline without moving it first to its own track and then inserting it back into the original.
Please tell me there's an easy way to do this!!!!

Hi Craig - totally understand why you are a little confused as to why I'd want to apply a job lot action but as a wedding videographer, I end the film with a slow motion film sequence of their day. Although each clip does need fine tuning to fit both to the music and to the general feel of the clip as well as fine tuning the in and out points, I do generally use a 50% slow mo as a rule of thumb and work from there. If this facility was available I could then do all the work from the timeline to fine tune which would be so much faster.
I had a look at the frame rate interpretation and while this does allow me to make a multiple quick change in the way that using a nested sequence would also allow me to do the job, the same restriction seems to still be there, in the fact that any fine tuning of the clip thereafter would be either difficult, impossible or quality would be compromised.
I've got to say though - I am impressed with these forums, in less than 24 hours I have had three or four suggestions all of which may work in a different scenario which I may be able to use, so thank you very much again.

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.

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.
