Slow motion rendering??

cigar_fiend · Post by **cigar_fiend** » Thu Oct 26, 2006 9:20 pm

I have just started using this product and I am very impressed with it so far.

I work at a college near Oklahoma City and I would like to use it for creating video files of our pitchers. Because I will be using it specifically for biomechanics and allowing the pitchers to see the mechanical problems in their throwing motion, I would like to know if it is possible to do slow-motion rendering from normal speed tape.

I have looked in the users manual and haven't found anything. But my experience tells me that users are usually more helpful than the manual.

Thanks in advance.

Not sure what you mean by slow-motion rendering, but you can reduce the playback speed by as much as 90%. It produces pretty good results, in my opinion.

Hi Chris, welcome to the forums..

,

You can change the speed of your video clips. The quickest and easist method is to right-click on a clip on the time-line. Then in the menu you will find the Playback Speed option. Be advised that any audio attached to the clips will also be affected. This is best used on clips without audio, or spliting the audio.

Great!

I haven't had a lot of video clips to play with yet, but I will try your ideas as soon as I do.

I knew users were smarter than manuals! Thanks guys!

For Vidoman... How easy is it to dump the audio. I haven't tried that yet, and would prefer the slow-motion parts be without audio.

For Black Lab... I was not 100% sure how to ask the question. The only other way I can think of is... "Can I slow down the 'normal-time' video that I get off of my DV cam and produce a 'slow-motion' shot of a clipped section within the captured video?" I still don't think I asked the question very clearly, but hopefully you get the idea. Because I am using it for my pitchers, I would like to take their bullpen sessions and create DVDs for them to send to Universities and professional teams. But more importantly I would like to be able to use the DVDs as a teaching tool that will allow them to correct the biomechanical problems within their throwing motion. If I can slow down the video it will allow me to show them the abnormalities easier. I am not looking for a frame-by-frame slow motion, just something that is around 50% or so. If I can do 90% like you say...I will be VERY PLEASED!

Thanks again.

There's some sample clips provided with the program. Load some of them up and play with the speed to get an idea of what it can and can't do. I also use MSP 8, and it has a better option for altering clip speeds, even a veriable speed function. You can have clip playing at normal speed, then slow waaaay down, then speed up real fast, and return to normal.

And as for getting rid of the audio, it's simple.

In VS10, with your video in the timeline, and if you are using the default screen set-up, then in the middle right of screen, there are a couple of tabs -- one labelled 'Video' and the other 'Attribute'. Just under 'Video' is a small digital clock (telling you how long your video is in hours:minutes:seconds:frames. To the immediate right of that is a tiny speaker icon, and beside it a small window with '100' in it. That indicates you have audio enabled and it will play at 100% of its original volume.

Method 1 for reducing the sound is simply to change 100 to 0. Method 2 is to look to the immediate right of the window with 100 in it, and there is another small icon of a speaker with a cross through it. That is the Mute button, and it will mute all the audio in your selected video clip.

There is a third method -- using the rubber band in Audio View, and pulling the handle blocks at either end of the line through the video down to the bottom of the track. This means the same thing as Method 1 above -- that you are reducing the volume down to zero.

Hi Ken I've tried to use this in Vs10 even when the band is right at the bottom the audio is muted but still so clearly audible that I render and transfer to Pinnacle Studio 8 for my audio editing. Even though this is a much older prog it is still superior to Vs10 for audio editing.

That's rather strange. I have been using the rubber band since it first appeared, IIRC, with VS8. It was admittedly primitive in that version, but has improved greatly in successive versions. And I have certainly had no trouble muting a track, or parts of it, entirely by pulling the band to the very bottom. Sure, it's a bit klutzy to handle, and takes a bit of practice to get used to. But it has certainly worked for me at least.

Like Ken, I'm a bit surprised the rubber band option doesn't work. However, another option you could try would be to split the audio (right click > split audio), then delete it (right click on the audio > delete). That should work, but then again, so should muting the audio.

peace.

Hi all back again I find using the rubber band so very usefull for fading into and removing those unexpected sounds ie talking, coughing, cell phones etc that may only last a couple of seconds and then fading back to the full audio track again. Cutting and deleting audio for a few frames creates a stutter since I can't fade to zero and spoils the overall effect. So I shall just have to carry on 'Cherry Picking' between Ulead and Pinnacle.

Thanks for all the input on this!

It has been very helpful, and the "test" video that I did yesterday worked Great! I did the 'right-click - slpit audio' and just deleted it.

Thanks to everyone!

All that really does is just mute the audio. You can just save yourself a few clicks by muting the video track(s).

Hate to tell you that though you might have split and 'deleted' the audio, it is still there. Just muted. Check your video, and then look at the mute button and you will see it is activated. If you click on it, it unmutes and your 'deleted' audio still happily plays. That is the reason I did not suggest actually 'deleting' the audio, only muting it in the first place, since the end result is identical!! And would achieve your purpose anyway.
