Yulia Lipnitskaya

You know I was thinking this for a while now.
I would loooooove to see Yulia work with Yuzuru's ex coach&choreo, for her choreography next season.
I don't remember her name now, I never remember:bang:, but I adore that woman. :love:

I wanted a free download program for myself. Matlab is free?

Alba, I have been reading about what is available. This one sounds good. http://download.cnet.com/Free-Video-to-JPG-Converter/3000-2194_4-10764760.html It is from the most reliable downloading source, you should have no trouble. There are some youtube tutorials but I doubt you'll need any--this one will make you feel at home https://www.youtube.com/watch?v=irT92niH8WI . The problem that I see is that you can't choose the number of frames per second. You can choose every tenth frame, for example. I think that 720p is about 60 frames per second, so every ten frames would give you a set of images at the rate of about 6 per second, which is about the same as my rate of 5 frames per second. I think you could try this even though it isn't quite as flexible as the one I have. But it is much more popular, probably the most popular free-ware for this purpose. It looks very easy to use. Let me know if it isn't okay, I can look further.

Oh I meant the video; given a video and what portion you want it to be "picturefied" I can easily convert it into an animated gif and post it on flickr. I guess in theory anyone could if they have Matlab.

Vanshilar, If you convert from this video https://www.youtube.com/watch?v=0YaVfbMwtO0 at 5fps, use only the section from about 1:40 to 2:45. Sorry I forgot to include this a few minutes ago.

Thanks, Sam. Do you know any free software that will extract a set of still picture images from a video, such as https://www.youtube.com/watch?v=0YaVfbMwtO0 at the constant rate of about 5 frames per second?

I'm sure my Sony Vegas does something like this. I looked up capturing still and exporting it and it seems possible. I guess if I can burn my movies that I make on to blu ray this should be well within it's capability. I'm not very good at computering myself so....:slink:

Ha that's great. Thanks Sam. I see there is the spanish version as well.
It's really interesting report, especially looking at those old skating blades.

WOW, it's so nice to see Butyrskaya again. I haven't seen her like for ages.
According to this she is a coach now?

Thanks Fayruza. Typical Yulia, fantastic expressive shape. For a completely different level of appreciation, her programs should be presented as an exhibition of sequential photos of about 5 per second. She is incredible, so fast and extensive that we miss much of her movement when watching. If any of you are interested in seeing her by-the-frame, there is a free software program called Video To Picture available at http://www.majorgeeks.com/mg/get/video_to_picture,1.html You can set the number of frames per second, it has the potential to generate literally 100,000s of pictures from a short video. I suggest you set it at 5 frames per second, then have it convert this video https://www.youtube.com/watch?v=0YaVfbMwtO0 from about 1:44 through 2:44. This will produce a set of several hundred sequential stills. This set of images is amazing for the incredible shapes she produces. She is magic. And the difference in shapes between each frame is far beyond merely amazing. The time from one frame to the next is 1/5 second, and in that twinkling of an eye she often moves so much that it seems physically impossible. We then realize that we see only a fraction of her movement in real time. They call this footwork. And she makes it all hypnotically beautiful.

I was thinking something similar to this when I was watching her SP from COC and her LP from TEB. Her programs may look "busy" as some people call it, but I just see an extraordinary level of attention to detail.

Did any of you you notice the way her arms change in her layback in her LP. It is just incredible. I find it mesmerizing how a seemingly simple thing (even the way the fingers of her free hand are positioned when she grabs her skate with her other hand) adds so much depth to her skating. No matter how many times I watch I always see something new.
 
Matlab isn't free, it's an extremely large program meant to handle some pretty sophisticated computations, and pretty expensive. It's completely overblown for something like this, heh. But I use it for my graduate work so I can write code using it somewhat, and it does have some stuff for image processing, so I simply wrote up some code for it when I started doing some of the analysis for Sochi.

Hmm wonder if I can effectively "compile" my code, I've heard that there's ways to turn Matlab scripts into stand-alone executables, I'll have to look them up though -- I don't know how to do it offhand.

Avidemux v 2.5.6 seems to have a "save selection as JPG images" option, so you can see if it works for you. It's a free, open-source program. Description about this can be found here:

http://www.cs.uregina.ca/Links/class-info/325/PythonMovies/avidemux.html

Note that this is an "outdated" version of Avidemux, they're up to v 2.6.8 now but it doesn't support this option, so you'll have to install v 2.5.6 to do this.

P.S. It works just fine on the video, I just tested it. It'll extract every frame from your set start point and end point though, but it only came out to around 64 MB for 1:44 to 2:44.

64 MB is in the ballpark if you extracted so many frames. The output pictures are usually small files. They don't have to be more for our purposes. I think the frame rate is about 60 fps for 720p resolution videos, so if you are extracting all the frames you will get about 3600 frames for the minute of video. That is actually too much detail. We get lost in very small changes of position. Can you adjust the extraction rate to approximately 5 fps, or can you edit the output file so that you save only every twelfth extracted frame (or tenth, etc--it doesn't have to be so precise, just get somewhere in the neighborhood of 5 frames per second) ? My target was 300 frames per minute. If you can reduce the output file to the slower 5 fps rate and put it somewhere accessible, then anyone from the forum could go there. I don't do twitter, so I can't do that. Thanks., Vanshilar

Isabel, Mesmerizing is the word. Wait till you see her at the rate of 5 frames per second. The speed with which she moves combined with the detail that you noticed seems impossible. If you are anything like me, your eyes can't process all that she is doing in a video. Without picturizing, as Vanshilar calls it, I see mostly the broad outlines. It's that detail you have observed that emerges with still frames. The position of a hand, of the fingers, changing in less than half a second while the entire body is shifting, arms moving. It is all deliberate. As she says, she is telling us what she feels. She is beyond amazing.

I'm thinking this had to be 2011-12 season. I think Polina Shelepen is even in this video and Evgenia is a little pipsqueak too.
 
Hmm were you thinking of separate images or as an animated gif? I can easily take every 5th frame and combine them into an animated gif (via Matlab script); I don't know if you were thinking of running them in real time (i.e. 5 frames per second) or slowed down to say 1/5 speed (so one new image per second). For example, this is extracting 5 frames per second, run at original speed:

https://www.flickr.com/photos/120676593@N05/15969887876/sizes/o/in/photostream/

Sorry about the colors -- it's because I'm squeezing the color palette somewhat to save on size. In fact the animated gif is 27 MB even though it's 1/4 the original size (640 x 360 compared with the original 1280 x 720). Basically, with animated gif's you're making tradeoffs between image size, image quality, and how many frames you're grabbing, against the overall file size. Making it 1/16th the size (so 320 x 180) means an 8 MB animated gif:

https://www.flickr.com/photos/120676593@N05/15808306798/sizes/o/in/photostream/

If these are moving too quickly, let me know and I can always slow them down. Basically I'm just changing parameters in an already-made script so it's easy to adjust for things like image size, frames extracted (more frames per second is smoother but means bigger file size), animation speed, etc. Keep in mind though that the better quality you want (larger images, more frames extracted, longer section of video, better color quality, etc.) means larger file sizes.
 
I wonder what's Yulia's problem with 3S. My friend was on her practice today (with my ticket :cry:), and she's fallen really hard. Again. I wonder if there's any videos?

Vanshilar, Sorry for the interruption, it was past my bedtime (almost 1am when I quit). I think we're okay with that extraction rate. Can you tell me how many photos there are in the file? If the video generates 60 frames per second (which is the frame rate for 720p videos according to what I have read) and you are taking every 5th frame, then that is 12 images per second of video. The total number of frames in your file would be 720. Can you determine if the file has about 720 images? I would like to get closer to approximately 300 photos for that minute of video. If you can tell how many images there are in your one minute file, then adjust the extraction rate toward 300 total frames. That will be close to 1/5 second per frame. The point is, I would like to get about 300 separate images per minute of video (5 images per second), presented in the order of the video.

Can you remove the animation? The animated gif version is interesting. I would also like to reproduce these as a set of approximately 300 still pictures, presented in the order they occur in the video. Like a freeze-frame gallery of her performance. The animated gif version is like a strobe light gallery. Freezing the individual frames will let us appreciate how much change of movement takes place in 1/5 second by studying her position in each image, and comparing the images. It's like a microscope, we see detail and change that is happening too fast when it is animated or with the video. If you slow it way down, that would be close and no doubt it would be interesting. But I'd like to see the set of images be presented as a gallery of still photos that can be clicked forward or backward.

The resolution of the individual pictures isn't an issue, email quality should be fine. The 640x360 is plenty. I doubt many will want 6x10 prints. If they do you can go into business. The colors are excellent, the subject is black on white, the background doesn't matter.

Let me say a little about what I am trying to do. I got started on this when I was freezing the video by clicking pause. I got a series of dance-like poses, many of which were dramatic enough to be framed and put on the wall. Then I ran it through my software producing a set of stills at 1/5 second intervals, I discovered just how much effort she is putting into a performance. It was a revelation. When we see how much change there is in 1/5 of a second, we better appreciate her achievement. It really is like a microscope, we see changes that go past us at a faster rate.

Thanks for your help. Again, I apologize, I fell asleep in my chair.
