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.

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.

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.

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 can I replay the video in slow motion?

I would like to replay my videos in slow motion on my iPad so that I can analyze my tennis and golf strokes.

I'd like to know how to do this now too since the terminal command doesn't work in Lion / ML. Anyone know how?
And Leroy - the reason is because I have custom hot keys configured and the shift key is a key I want to use for this command. I would like to know how to disable the slow motion effect permanently since I never need it and would certainly like to use my shift key as a modifier for various keyboard commands.

Record and playback video in slow motion

Hi
I am COMPLETELY new to labview and am having some trouble.
I would like to record a video using a USB camera and be able to play it back on multiple occasions at different speeds.
The file attached is what I have so far. The signal generated at the top is controlling the equipment I am recording. Currently, I am saving the video to the hard drive in AVI format and retreiving it to watch again. However I would like to be able to play this at different speeds and be able to pause/rewind. Is this possible? I would also prefer not to have to save and retreive the file and much prefer it to stay within the system memory.
Thanks in Advance
Alex

Hi!
In your program you set the "frames per second" input on the "Init AVI" Vi to 50. If your camera is set up to acquire 50 frames/sec this is ok. But your "playback" loop will (as it is) run at much higher rate, since it is not limited in speed. You need to control the playback rate with a delay function (maybe the Wait (ms)-vi). If the acq-rate is 50Hz, you need to limit the playback loop to 50 iterations per sec -> 20ms delay.
Set the delay to a lower value for a faster playback, or higher value for slow motion playback.
If you decide to use the AVI-vi:s you need to associate the video with a file. You can however keep the frames in memory by simply create an array of images and write to them instead of to the AVI-file. Modify your code like this:
1) Create an array of IMAQ-images, Note that you need diffrent images on each index in the array.
2) In your acqure-loop. Instead of writing to the AVI-file, write to the array at index "i". Note that you must modify this image, so retreive the image-ref at array index "i", then modify it by writing to it, the put the image-ref back in the array.
3) In your playback loop.Read image-ref to display from the array by index "i".
Done
Best regards

Is it possible to put videos in slow motion?

Is it possible to put videos in slow motion?

Yes, probably the easiest method is to use the Time Stretch Tool and just lengthen the Duration of the Clip. Or Rt-click and choose Time Stretch to do this numerically.

Is it possible to my play my uploaded videos in slow motion?

Hello All,
I have the macbook pro and I am trying to figure out how to play my uploaded videos in slow motion.
I am using the quicktime player version 10.1 and I am only seeing the ability to playback, pause, play, enlarge screen and fast forward through my videos.
If it is not possilbe to get the videos to play in slow motion using quicktime, I would appreciate suggestions on software that I could get. Nothing complicated, I just really need that slow motion feature! Thank you!

I have the macbook pro and I am trying to figure out how to play my uploaded videos in slow motion... I am using the quicktime player version 10.1 and I am only seeing the ability to playback, pause, play, enlarge screen and fast forward through my videos.
This capability is dependent on the media player. QT X.1 does not have either a slow or fast motion playback feature control. The closest you can get is holding down the right arrow key in which case the "slow motion" spped will be dependent on your computer's CPU power and the clip's frame rate.
If it is not possilbe to get the videos to play in slow motion using quicktime, I would appreciate suggestions on software that I could get. Nothing complicated, I just really need that slow motion feature!
The QT 7 Player (free) can play files with sound between 0.5 and 3.0 times normal speed. The VLC player (free) has a wider range of speed variations with sound but audio usually drops out at below 0.25 times normal playback speed. The TV player also has three slow speed (and fast speed) playback options but I don't know their exact speeds and it is without sound.

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?

Can the iPhone 4 shoot video in slow motion?

Can the iphone 4 shoot in slow mo? This video says they shot it in slow motion but I don't think it can?

This question is too funny...
Nothing can shoot in slow motion (since things always occur in real time). You can only *play back* a video in slow motion (i.e., reduced frame rate).....

Shoot 720p 60 for Slow Motion on PAL DVD . . ?

Ever since I became interested in shooting slow motion, I've been quite envious of NTSC users because they enjoy 30 fps rather than PAL's juddering 25 fps.
Interesting to note that the +'grass is always greener'+ syndrome has kicked in though. A great many NTSC video makers are desperate to achieve the +'film look'+ while many over here, want smoother footage.
Personally, I fail to understand why anyone would want juddery footage, but then I detest the wavy camera phase that film makers are going through at the moment. Now I'm showing my age.
With the galloping technical advance of 'prosumer' camcorders, we now have a choice of formats and this has led me to wonder whether shooting in 720p 60 fps and then converting this to PAL DV could achieve a nicer slow motion than shooting 720p 50 fps.
I'm not in a position to run any trial just at the moment, but the idea's been in my head for a while now, and I wondered if anyone has any thoughts or experience on this.
Because of the nature of my subject, I cannot predict with much accuracy which scenes will be required at normal speed and which will be slow, so I shoot everything at 50 fps and then I can choose.
+PS. I'm not very technically minded so forgive me If I've overlooked some obvious flaw!+
I should add (although it's surely obvious) that I shoot in HD in an attempt to 'future proof' my footage. The vast majority of my audience has only recently converted to DVD, let alone HD.

Sorry, did kind of lack technical details but then there are precious few to consider, after all, overcranking (running a camera at a higher recording framerate than the intended playback framerate) has been the way this has been done for years, and the new video cameras that allow 60p recording make an ideal poor man's high speed camera, especially for 24p and 25p playback. Also its much easier just to tell folks what they want to hear

New Sequence Question - for slow motion video

Hi,
I'm a very new user of Premier. I've recently had issues with choppy playback of my preview videos. After much research I believe the issue was down to two things. Firstly my sequence did not match my input clip, I had it set to my desired output. Secondly, I was editing video across my network, rather than bringing it locally to my PC. I've fixed the latter issue by copying video files to my local machine and then moving them back onto the network once I've finished editing.
The advice out there essentially seems to be to match your sequence to your primary input video. I've done that and it helps. However, it's raised a big question for me. My input video is from a GoPro and is at 1080p 50fps. I ultimately want my output video to be slowed down to 25fps (resulting in a constant slow motion effect throughout the entire sequence).
If my sequence settings are set to match the input clip (50fps) and I slow the video down by 50%, will that result in an unsmooth video? My basic understanding is that if I slow 50fps video down by 50% then Premier will have to double the amount of frames. Where as previously, if I slowed it down by 50% Premier had enough frames to play with as the output video was 25fps.
Hopefully my question makes sense! Any advice on what the best approach is? Or is this a complete non-issue when it comes to exporting the video (providing I export to a 25fps formart)?
Thanks,

I think you said it OK, you are just missing the right words to do what you want. Let's walk through this for you, and for others that might read it later.
If you take a 50 frame per second video and put it into a sequence created from it, then slow it down 50% it doubles up each frame to achieve slow motion. Not what you want.
If you take a 50 frame per second video and put it into a 25 fps sequence, it drops half the frames to play at normal speed. Not what you want.
What you want to do is interpret the 50 fps video to 25 fps, then drop it into a 25 fps sequence. Each frame will play at 25 fps and generally be smooth as silk.
I don't have any 50 fps clips handy, but here are examples of taking 60 fps to 30 fps. (Excuse the idiot way that we Americans do things. Our 30 is actually 29.97 etc)
First, right click on the clip in the Project Panel, select Modify, and Interpret Footage. Then change the 50 to 25 - similar to this image:

Video shot specifically for Slow Motion playback

I thought I might try starting a thread for sharing video shot specifically for the purpose of playing it back in slow motion. For the first example, I shot this flag flying on a perfectly clear day. We have had a lot of really clear blue days lately much to my delight.
My Panasonic DMC-GH3 can shoot 1920X1080 at 60 (59.94) frames per second. That is frames, not fields. So interpreted at 29.97 frames per second it plays half speed. This was taken a step farther and played back at 24p. So if my math is correct, it is playing at 40% (close enough).
Funny, but the camera actually has a setting to shoot video to play back at 40% but it seems redundant to me. Perhaps if the video was never going to be edited, just played back, that could come in handy.
I used a recording from the US Army Band because I was in the Army and I am just used to hearing it played by the Army Band. I thought of adding the lyrics since I really like them. All four verses. I just didn't have enough footage to do it right and I love the sunshine and blue skies. So here is a link to the four verses for those who want to play the video four times and sing along. Nobody? Are you sure? I did it. Couldn't help it.
I am probably going to put up a couple more copies. One with the Pledge of Allegiance and one with the first verse of the National Anthem. In the meantime, I am enjoying all that blue sky.
If your camera can shoot at a higher frame rate to play back at 24p, please post some examples. If you are particularly good at using Premiere Pro to modify the playback speed of video, let's see what you've got.
The camera was siting on a GorillaPod shooting at approximately a 30 degree angle. The lens was my 100-300 set for 183mm, the equivalent of 355mm on a 35mm camera.
ISO 200. This video has not been modified in any way other than interpreting it to play at 24 frames per second, to trim off the beginning and the end (to eliminate the shaky setup and take down of the shot), and I also added cross-dissolve transitions at the beginning and the end. No color correction of any kind and no stabilization. This is what the camera saw.
I really love the flag of the United States. If you live in the United States I hope you do too. Today is Washington's Birthday. So Happy Birthday to the Father of our country. Our first President. This is my present to our founding fathers on this day, and I chuckle to think about how shocked they might be at the number of stars on the flag, and I am sad when I think how mad they would be if they knew how far we have strayed from the principles they fought and died for.
(I'll bet old Ben Franklin would love the Internet though.)

Steve, regarding my request getting inside flag and changing shutter speed etc..
I have to admit right off that I don't understand this myself as I should...and I don't have a motion pic camera OR the DSLR ....which I can get in April ...at which time I will be off to the races trying to figure out how to use it.
But the gist of what I was getting at ( though hazy and not understood by me ) I'll try to explain...
Motion pic film cameras with the mechanical gizmo that pulls down the film ( frame by frame ) have a rotating shutter ( the gizmo is typically called a mitchel movement I think ). The rotating shutter has a mirro on the back side which allows a person to 'see' via some magic stuff ( prism ? ) what is in the frame ( eyepiece ). I guess it's similar to a SLR mirror but this one spins.
This is what it looks like
So, a normal setting for that shutter is 180 degrees... and it spins so that each frame gets 'exposed' by the open part of the shutter. Then when the shutter is spun to the closed side ( no light getting to film frame ) the 'next frame of film' is dragged down into place to be exposed. So that happens typically 24 times per second. It is pretty fast.
Some motion pic cameras can shoot even FASTER ( amazingly )...and you can therefore increase the FPS. Then as you know when it's played back at 24 FPS in projector, it looks like slower motion.
Unfortunately if the FPS is increased the 180 degree shutter may not be letting in enough light to get a good exposure anymore... so that shutter can be adjusted ( called the shutter angle ).
So a 45 degree shutter would let a lot more light hit the film ...cause it lets more light through its rotation time. This is the part where I can totally confused....and hopefully I'll learn more when I get the DSLR how this is handled with modern digital camera.
Cause, if you let more light hit the film by adjusting film motion pic shutter it stands to reason there will more " blur " from the longer exposure. However, this is offset by the faster FPS speed... so this is why I am curious about it...
As a point of fact motion pic cameras can be synchd to CRT screens using a mechanism that times the shutter to coincide with the horizontal 'lines' of the CRT ( timing of frames of interlaced signal )... and the shutter has many 'angles' it can be adjusted to ..
So, anyway, I guess this is something to explore when I get that DSLR...
I was thinking it might look cool to have slo mo with more 'blur' to make something look a little ghost like...kinda like my flag picture with time exposure...
crazy idea...

Question about Camera/Premiere Settings for Slow Motion Video

I'm new to shooting video with cameras that have manual options, so I'm not exactly sure how I should set up the camera settings. It's a Canon 60D. Basically in the video I want to make, I'd like to have a lot of normal speed to slow motion transitions. Some of the video footage will be very fast paced, so I'd like to slow it down as much as possible without making the video appear jumpy. I assume I should change the frame rate on the camera to 60 fps. Is there anything else I should adjust within the settings?
I will be editing with premiere elements if you know of any additional tips for that.
Thank you in advance!

The speed of your camcorder doesn't matter. You can apply Time Stretch to any video clip.
There's a limit to how much you can slow it, of course. With that camera and Premiere Elements, you're not going to be able to slow down a water spray so you an see the individual droplets or anything like that. But, if you combine TimeStretch and Frame Blend, you should get very good results slowing your footage down a certain amount.
How much you can slow it and still be satisfied with the results is kind of a judgment call. So I encourage you to experiment and see what your tolerance is.

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.

Imported Video not in sync with sound. Video in slow motion...

Hello,
I am fairly new to Premiere and I wanted to spend some time playing around with it. When I import my videos, the playback is out of sync. The sound is normal but the video is in slow motion so it doesnt sync together. Am I missing something? Using Premiere Pro CS4 and filmed it on a Sony Xacti with MPEG4 AVC sequence.
Thanks in advance.
Steve
Oh by the way, it seems to open and play just fine in any other media player

Steve,
Glad that you got some material to practice with. That was your goal here.
Now, file conversions from compressed source material will usually not yield great quality. Unfortunately, the conversion process, unlike what some would love to believe, does not restore quality to the compressed material. It only changes some of the characteristics, but imporved quality is not one of them. Also, depending on the actual conversion program used, the quality can suffer even more. This is a fact of life in Video.
Now, when you go to get your camera, there are many great threads on many camera makes and models already posted. If you cannot find info on your considerations, post to get recommendations, based on your budget and what you wish to use the camera for. I'm not positive, but I think that the new Equipment sub-forum would be a good place to ask. Previous posts will not be there yet, but will be in the general forum. Many, but obviously not all, cameras have been discussed in length, and their pluses and minuses have been debated.
Good luck,
Hunt
