Nice work!
How did you do it? Move very slow :-p?

Gonna make myself vulnerable to foot-in-mouth disease here...

He probably shot 60i and converting that to 24p, each field taking up its own frame. 40% slowdown that way.

After that, optical flow or similar technology/filter to slow things down further. Boris Optical Flow, latest version of Shake, revisionFX, etc.
He could've used field blending... the resolution makes it hard to tell.

EDIT: You know what? It only looks like he slowed things down 2-2.5X. He just moves slower after he starts... so because he moves in slow motion, it actually looks like it's in slow motion.
To get 2-2.5X slowmo, you just need to do the 60i-->24p thing.

EDIT2: If you look at the quicktime clip, it's 29.97fps without 3:2 pulldown. So the slowdown is probably just 50%.

He used a revisionFX like filter. Just see at the skirt when it's closer to the camera. No doubt about that.

Could you not just slow the speed of the clip down to 50%? I am curious to know how he did it too.

Malon,
So are you going to tell us how you did your slow mo?

Lloyd Choi
October 13th, 2005, 05:35 PM
with my DVX, I shoot 60i at 1/120 shutter speed. when I slow it down by 50% in a 24p timeline, it's smooooth slow-mo like his.

It has ot be 50%, or else it will become jumpy.

which editing software did you use?. Cuz I am sure other editing software might not act exactly the same way?
Also, can you please post a video clip or something so that we can see a sample or something?
Preciate it man!.

Heheh. Forget him, guys. I'll let you in.

Use MotionPerfect from GooderVideo. (http://www.goodervideo.com/products/MP.html) Don't let the cheesy low-budget-look website fool you. Their product is amazing. It calculates what the frames inbetween the existing ones should look like and fills in the gaps. You can get incredibly smooth slow motion using this program.

Pssh. Secrets are no fun.

Thanks Ben,

The demo clips look very smooth. I need to do one slow mo scene in my next project and this may be the ticket. The price is right too.

Steven Fokkinga

So how does this program compare to twixtor and retimer? The price is phenomenal if it can do the same as those programs!

I just now tried the trial version of Motion perfect with 2 clips.
One interlaced clip and one progressive. For whatsoever reason the Progressive clip looks better than interlaced.

Its...
# awesome
# smooth
# affordable.

Thanks a bunch Ben.

Also, can anyone please eloborate the procedures to be followed while shooting a stunningly detailed slow-motion sequence in DV and what settings should I have in my Camera. Mine is a DVX - 102A (PAL). Thanks in advance.

Thanks for posting, Ben W.

Yes, Gooder is just one of the many reseller sites for Dynapel's products.

You should have seen the old clips on Dynapel's site before they redid it (it was better before). I have them cached locally and will host them on FTP so you guys can see.

Edit: Looks like Gooder has a local version of the page from Dynapel's old site, here:

http://www.goodervideo.com/videos/MpVideos.html

Check out the race car vid if it works. Amazing. Let me know if it doesn't work, and I will host it.

The software is so cheap, like 17 euros.

The program looks like it uses a really nifty morph effect between the frames. I remember seeing something similiar using winmorph to recreate bullettime.

Shots like that are EASY.

I use Boris Continuum Complete Optical Flow Filter. It's not hard for the filter when it's a single moving object with a solid background.

Try several moving objects that cross paths against a complex background. Settings for Optical Flow get REAL TRICKY then.

The shot he posted looks fine at default settings except for the speed itself.

Hello

What good plug-ins are available for vegas or stand alone that can give very slow motion? like this below

Try this reseller of it; they still are showing the old MotionPerfect clips from Dynapel's old site. I still don't know why Dynapel took them down; they are great examples. This one is 20:1 speed reduction:

I had tried out this software but it did not work for me and there isn't any contact info for the developer. What I am looking for is very similar to what is being displayed in the video of the "Rugby" team, it is the last option on this page:

http://www.goodervideo.com/videos/index.html

When I opened up the video of the rugby team, I believe it was using "quicktime" player so I tried out quicktime player but this did not do the trick so I am guessing that it was the combination of both the Gooder slomo software and quicktime that was producing those results but becuase I cannot contact the developer this is still a "guess".

Anyway, my son plays sports and I wanted to have this exact type of slomo control when veiwing his games which I record with a Canon digicam. I do not have much money to spend on expensive software so I am stuck. If anyone here can take a look at the link provided and download and try out the Rubgy video clip, just move the "play" slider as quick or as slow as you may want to to the left or right and you will see that you can control the slomo in the same way that the NFL or NBA does, this is simply what I am looking for. I wish to control my son's game film in "smooth" slomo by dragging the slider at whatever speed I wish.

Can anyone shed any light on that Gooder video or recommend any other software that does it like this please? Thanks.

Ben Winter

That means controlling the derivative of velocity: acceleration. Sorry to get all "mathy" on you but that's what first jumped into my mind, controlling the slope of the tangent to the graph of how fast the clip would play. I don't think MotionPerfect does that at all; you would want to use the Time graph settings in FCP or something similar to that. Look for some kind of "acceleration" control for video clips, maybe that's what you're looking for. Otherwise, look for an NLE-integratable plugin like MotionPerfect that has keyframmable controls.

Mike Henderson
December 5th, 2005, 12:44 PM
well Ben, I really don't fully understand what you wrote but I will do some searching and look into what you've told me, if I could contact whoever did that particular Rugby video slomo, I would have all my answers, appreciate the help Ben, will report back here if I find anyhting, thanks.

The rugby slomo was done by the Dynapel software from Goodervideo's site. No other software was used. Their software uses a type of "morphing" between original video frames. It uses the original as keyframes and extrapolates new frames between using intelligent "morphing" techniques. Download the demo software for free and test some of your videos. It is a standalone application, so you don't need a specific plugin.

Mike Henderson
December 6th, 2005, 05:24 AM
Exactly "which" software are you referring to please? I had tried out the "Slowmotion" software on that site and this did not do what the Rugby video showed, please advise, thanks.

Rick Steele
December 6th, 2005, 06:14 AM
Well, I tried the MotionPerfect demo on a test AVI made in Adobe Premiere slowed to 50%.

I can't see any difference. My test AVI required no additional frames to be created by MotionPerfect. I suspect Premiere already did this?

I'm thinking that the DynaPel products are designed for converting choppy video with non-standard frame rates (like from a web cam) to full frame PAL or NTSC. Indeed that's what DynaPel's demos videos seem to show.

Mike Henderson
December 6th, 2005, 06:35 AM
In my situation, I record my video's from the Digicam into the pc and simply wish to have the slomo done exactly like with the Rugby video without having to modify the video in any way [slowing down the speed e.t.c], I wrote to Dynapel's main Technician yesterday and I am waiting on his reply to find out what I need to do be able to control my avi videos in slomo in the exact way that this Rugby video does it with the quicktime player, will report back here if I hear from him.

Marcus Marchesseault

Slowing the video down %50 will double it's length. It's as simple as that. Why slow it down in Premiere, then slow it down again in MotionPerfect? That would quadruple the length of the video. You are just doing extra steps and Premiere won't give you the smooth slow motion that can be achieved with SlowMotion or MotionPerfect.

Quicktime is not being used to slow the rugby video. Dynapel's software slowed it down and Quicktime is simply playing it. Quicktime thinks it is just a normal video. New frames were generated by SlowMotion to keep the framerate smooth.

I downloaded SlowMotion from Goodervideo and it does exactly what it should. It takes in a standard video file and slows the motion down by increasing the number of frames. When played back, it looks slow because it is a longer video file. It plays at the normal framerate, it just has more frames to play so it will take longer for the same action to take place.

Mike Henderson
December 7th, 2005, 05:44 AM
I hear what you're saying Marcus but please understand that I am trying to get the same result from my video files as with the Rugby video and this is just not happening with the slowmotion software on it's own so something is missing here and that is why I wrote to Dynapel's Tech, still haven't heard from them.

Rick Steele
December 7th, 2005, 06:57 AM
Slowing the video down %50 will double it's length.Yes.

Why slow it down in Premiere, then slow it down again in MotionPerfect?Let me clarify.

- I have a 1 minute AVI source at 100% speed
- I use Premiere to render that source at 50% speed
- Used the same source in Motion Perfect at 50%
- Put those two side-by-side... No difference.

The frame counts are pretty much the same too. After researching some functionality in Premiere Pro 1.51 it seems it does its own "frame interpolation" just like MP but I'm sure the algorithm is different.

Again, MotionPerfect indeed does what it claims as I can't tell the difference between the two clips. I was just hoping it would do a better job at "frame blending" using a 29.97 source but it appears it only inserts redundant frames where needed (which is what premiere and other NLE's do anyway).

Now if one were to use the Rugby source footage in this test, Premiere would not do what MP does so again, I'm guessing it's only good for using non-standard frame rates as the source footage (like taking 15fps from a web cam to 30fps)

This is all speculation on my part as I've really never thought about what happens when rendering slo-mo. It's very interesting and I'm learning a lot.

Marcus Marchesseault
December 7th, 2005, 07:37 AM
Nope, it doesn't just insert frames. Read the FAQ on Goodervideo's site. Also, look at your two 50% clips on a good NTSC monitor at full framerate. Don't use your computer as it's framerate can be variable. I'm sure you will see a difference. If you don't, use MP or SlowMotion to it's slowest rate. Do the same rate with Premiere. I'm sure you will see a difference. If that doesn't work, run the SlowMotion clip through the software again slowing it to something like 1/6th it's original speed and you should see a huge difference. The rugby video is something like 1/15th the original speed, so one might need to run the video through the software a few times.

Mike Henderson
December 7th, 2005, 07:41 AM
Let me see if I am understanding this slomo thing correctly, are you saying that I can take my son's game's video avi files and slow it down first then import it into Quicktime and get the same manipulation as with the Rugby video?

Mike, forget quicktime - take it out of the picture as it has nothing to do with the task at hand. The Rugby sample footage was "converted" to quicktime to make the download smaller. Prior to that conversion the original file was an uncompressed AVI.


If you don't, use MP or SlowMotion to it's slowest rate. Do the same rate with Premiere.Well, I did the same test at quarter speed. Things look worse in MP but and the Premiere render turned out much better. Again, I couldn't tell much difference in scenes where somebody is just walking but when using MP at 25% speed for something like a golf swing was unacceptable - the blurring is too choppy.

I'm not downgrading this product. I just think there's a reason why it's priced the way it is. (vs. Twixtor or RealVis for example).

The reason why I mentioned Quicktime Rick is becuase of the "slider" manipulation, when I move the "play" slider on the Quicktime interface [with the Rugby video], it gives me the smooth slomo like the NFL/NBA e.t.c, this is what I need, ok so I am guessing from your post that I can use "any" interface for this that has a similar slider? If so, then what do I need to get the slomo itself like in the Rugby video?

Rick Steele
December 7th, 2005, 08:49 AM
I can use "any" interface for this that has a similar slider? If so, then what do I need to get the slomo itself like in the Rugby video?I don't know what slider you're referring to in QuickTime and no you don't need it to use the Dynapel's SlowMotion software .

Using the SlowMotion software merely open your source AVI and allow it to do its thing (try half speed). The resultant file will also be an AVI and depending on the frame rate of your source file can be much larger than the original.

Try playing that AVI in Windows Media Player.

Mike Henderson
December 7th, 2005, 08:58 AM
The slider is question is the slider on the bottom of the interface that moves from left to right, what I do is I click on it and drag it either to the left or right to go forward or reverse and however quickly I feel to and the slomo is not choppy, it is very smooth. I had tried it in WMP and "every" other player [also Quicktime] that has a similar slider but only got choppy results.

My question here would be "how" to get the my avi to show in slomo like the way it shows in the rugby video when I move the slider. I will try the Gooder "slow motion" software again, this time at a slower speed like you suggested, I don't think I had done this before, will get back to you in afew, thanks.

Mike Henderson
December 7th, 2005, 09:48 AM
I played with the slowmotion factors but again, main problem, the Gooder interface does not have a slider for me to drag to control the speed of the slomo? I am wondering now if I can slow down the speed of my video file, save it and then import that into quicktime, would this do the trick?

Mike, you have some kind of fixation with this “slider” thing. :) Forget QuickTime, Forget the slider, forget everything you’ve ever heard about these two terms. Let’s start over.

(1.) If you haven’t already done so, download the SlowMotion software demo here and install it.

http://www.goodervideo.com/download/SlowMotion_Install.exe

(2.) Start the demo

(3.) In the “Input” section click the Browse button. Navigate to any AVI you want to apply the slow motion to. I’d suggest chosing something real short (60 seconds or so) as the rendering process will take a while.

(4.) In the “Video Settings” section let’s try reducing the speed to 50%. (Slowmotion Factor 2).

(5.) Next press the “Video Compressor” button… just to the right. Under “Output Compressor” choose “DV Video Encoder”. Make sure compressor quality is set to 100%. Press OK when you’ve done this.

(6.) Note the location file name given In the “Output” video section. This is where you’re finished clip will end up once rendering is done. Browse to a different folder and rename it if you want.

(7.) Press the “Start” icon on the toolbar and let it do its thing. (Depending on the length of your source AVI It’ll take a while). Also, the demo will watermark the final result.


Are we gettin’ anywhere yet?

Mike Henderson
December 7th, 2005, 10:58 AM
Rick, really appreciate the step by step, thanks, but my fixation with the slider is neccessary for my purpose. See, I absolutely need to control the slowmo in a sorta frame by frame mode but I also need speed control with my hands, I really don't know how to put this into words. I will only be using this for sports and for sports purposes, especially Football, I will need to see slomo run at different speeds and sometimes "consecutively". I have tried using hotkeys for this with certain applications that don't have sliders or jogwheels but there is NOTHING that gives you the control like either a slider or Jogwheel so unless I can import and view the modified file in WMP, Quicktime or any other application that has either a slider or Jogwheel interface, this will be pointless I'm afraid. What all of this means is, if I were to be sitting "watching" a video file then this would work to watch it in slomo but for my purpose I need to manipulate every frame of the clip.

So this brings me back to my previous suggestion, can I modify the video and then import into another player with a slider?

Rick Steele
December 7th, 2005, 11:42 AM
See, I absolutely need to control the slowmo in a sorta frame by frame mode but I also need speed control with my hands, I really don't know how to put this into words.So it's the video "playing" functions you're after then I take it. This whole topic has been about rendering a full speed movie file "permanently" to slow motion which is not what you want.

Hmmm... as you said, a set top DVD player should provide what you want (some will even advance frame by frame) but I'm not familiar with a PC player that does this off the top of my head (specifically, the frame-by-frame feature). But I'm sure there's something out there.

Do you use a video editor? Why not try that?

Mike Henderson
December 7th, 2005, 12:07 PM
I am so sorry for leading all of you down the wrong path here, I heartily apologize! I am looking for slomo functions which is why I posted here. I have a remote for my Canon Digicam and can advance frame by frame when I connect it to my TV but the slow motion controls on a handheld remote does not work like pc software unless you're using $30,000 NFL equipment I guess.

So it is not the frame by frame itself that I am after, it is the way I can manipulate the slomo using a mouse/jogwheel and pc software that I am seeking. There are only 2 main softwares that I have tried that does this, Pinnacle LE6 and that Rugby video with the quicktime player. LE6 is waaaayy out of my budget [$600] which is why I am looking into the Rugby video setup hoping it will be a lot cheaper.

Hope the above explains things better this time. I don't really know what a Video "editor" is/does but I am glad you mentioned it, I will start looking into it, if you have any more ideas, please post, also if you have a links to a good video editor, that will be very helpful, thanks.

Rick Steele
December 7th, 2005, 04:13 PM
I don't really know what a Video "editor" is/doesIt's something you've already tried (Pinnacle Liquid Edition 6). These editors are also referred to as NLE's (Non-linear-Editors).

LE6 sounds like it's overkill for what you need. Have you looked at Windows Movie Maker? It's free and probably on your hard drive right now. (Not sure if it does slo mo though). It won't burn a final DVD but it can generate an AVI.

Or I'd suggest checking into some of the sub $100 editors out there like Vegas Movie Studio, Power Director, Ulead Video Studio, etc.

The all can work on video at the "frame" level. Just make sure it has the ability to adjust the speed as well. (I believe they all do - just make sure).

Mike Henderson
December 7th, 2005, 04:23 PM
I had tried Ulead a while back, too choppy, will give the other 2 a try, thanks.
