I thought I'd try out videoing the training sessions.
What setup and particularly software does anyone use?
I have a Sony Camcorder connected via firewire to a laptop. I then use FMV software to control the camera and show the throws full screen on the laptop but playing from the camera. Saving the file onto the PC and rendering seems to take an age by which time the points of the coaching for that throw have passed.

www.quintic.com is the best thing on the market you can download the player for free. it's the software that John Trower uses for steve backley and all county cricket clubs and golf pro's to analise every part of every movement

Has anyone tried tyo use that Quintic software? I've tried to use it but it runs really slowly and a lot of the functions don't work. Does anyone know of any basic software that is free for download or even that you can buy in the shops? I have started to record some of my various events and the findings are very interesting, particularly my tripple jump technique. I realised I'm actually jumping around 10.5 metres for my first 2 phases and only 3 and a bit for my last one!
I just want to find something that I can use to play films in slow motion and cut parts of the clips out so that the file size comes down. Any suggestions, please let me know.
Cheers,
James

Give this site a try: www.download.com/! Search for video editing software or something along those lines and you should get some results.

Cheers Ant,
I found a couple and the best one I've found for cutting down the size of files and the length of files is called VideoEditActiveX. It allows you to string one clip onto the end of another and then delet parts of the clips and change the size of the file accordingly. Its worth a try if anyone is looking to do this sort of thing.
I plan to post a clip of me throwing tomorrow so I'll prepare myself for some severe crticism!

There were a couple of points I was interested in when making the post and since then have done some more investigation.
What is very clear to me is that without video analysis it is very hard to see what happens at the point of throw. You can tell a certain amount by the flight and the naked eye but actually in those fractions of a second it is tough to see. I wanted to be able to give reasonable feedback to the throwers right *there and then* on things to work on. For example the stepovers on the approach are much easier to show in slow motion at a top level and the using the Quintec type software later to draw a line showing whether the body stays horizontal through the sequence
The video analysis software looks great but you still in my understanding you have to render the video and it I agree that it works slowly especially on a laptop battery powered in the middle of an athletics track! This is made worse by the reflection of the screen so top level concepts are really all you can get over in the training session.
I haven’t therefore played with the Quintec/Dartfish type software much and I’m wondering if anyone has used it for real and give a review. I was going to approach the club to see if they would contribute to the cost of the software (because the application is across the whole of the athletics arena) and wanted to be able to point to a successful implementation.
Even with the slow motion the action in those fractions of a second is still too quick for my average video camera is there a better solution? Have you tried camera’s with sport mode?
I guess what I’m trying to find out is what works best in the real world. Whilst not a thrower myself and therefore do not “the feeling of the throw” however I understand the physics, biometrics and science of the throw. It is one of the most technical athletic disciplines (I’m sure others may have a different view!) with so many things to go wrong I wanted to try and make the coaching a little easier.

Quintic is the choice of most sports for motion analysis software but it is at a price and I have tried all of the others, ie, Dartfish,Cswing etc etc. but I only have analogue set up, not digital so I find that the software is both unreliable and grinds to a halt when trying to render or playing back fairly big portions of vids. I do not use a lap top trackside but use analysis on my home comp after the event. If you want to capture direct from camera and quickly analyse it then I find that the"Classic Media Player" is just as good but do not confuse this with the ordinary Media Player this one is free and can be downloaded from sourceforge.net/projects/guliverkli/Look for the "Media Player Classic MPC 6.4.8.2" and once downloaded you will find that this has quite a few surprises to it and is a powerful tool for video playback and analysis plus of course it costs zilch, totally free. If you need to draw lines, angles etc then Camtasia is also a good package for this type of work. Without going into the complexities of motion analysis I hope this info helps if anyone is wanting software for no outlay.

Interestingly, (or sadly dependent on your view) I have been doing some more work on this to come up with a free-ish way of capturing decent video for analysis. One of the things that I have found is that the action is so quick as to make looking at the throw fairly blurred even when using step through through on a media player such as MPC. Now I've learnt that video plays at 25fps but is actually captured at 50fps (using fields) so if you can break up the video to the higher defintion then the video is really clear. The methodology is explained at www.100fps.com. It has taken me time to get to the stuff working but the components are free. The resulting file sizes are quite large which is why I can't post a sample. Of course Quintic does this but in the £1000 version! If its any help or interest to anyone I'm happy to explain more or help you get it working, the clarity is worth the effort.

Here is an example of the Video technique of my previous post. Warning! The first file is 1.2mb and the second 1mb. 50fps www.enriched.co.uk/50fps.aviCompared to: 25fps www.enriched.co.uk/25fps.aviI recommend the MPC player to analyse both sourceforge.net/projects/guliverkli/ and then use the framestep (button on extreme right of playing buttons) to step through. Hopefully you'll see that the level of clarity on the 50fps is considerably different though a larger file size. The 25fps whilst OK shows the effect on fast motion where you can two javelins on occaissions where the two fields are combined together. BUT my really question is, and what this is all about, is technique. He starts to throw the javelin before the left foot is planted if you look at the 50fps clip, how do we stop this!! Again if anyone needs help creating these videos please don't hesitate to ask!

Our club high jump coach uses V1 Home. It's designed for golf but works very well for athletics. A free trial verison can be downloaded from www.v1golf.com/consumer/default.asp and the full version is about $40

Hey Sam,
Is the Quintic software compatible with most Digital / DVD movie cameras. I'm thinking I've buying a Sony DVD Camcorder

I have a question about the actual video.
Is that person's jav angle too high when they throw it? I'm curious because I've seen videos of myself throwing and I have about the same angle.
