Hello,
There are some cams out there now with high speed shutters for slow motion. Set it for 120fps and replay it and it is awesome slow mo.
I have an old (10yrs) panasonic video camera. It uses the small VHS tapes. You need and adapter to play them in a vcr. I have recently been converting my old vids to DVD.
My main question: After playing around with it for the first time in 7 years, I found that it has a high speed shutter button. When you press this button you can scroll through 1/60, 1/100, 1/500 etc...all the way up to 1/10,000. Of course when you do this, you have to have lots of light going above the 1/500 mark. I've never used this in the past.
Can anyone tell me if I use say 1/1000 fps on this video camera and then transfer to my computer and slow down in Premiere will I get quality slow motion?
For example, on my current 1/30 sec vid cam, if I slow down in premiere it is just that....slowed down...you don't get the great slo mo effect.
Will my old vid cam act as a true high speed shutter? Or am I overly optimistic?
I will not be able try it for a few days but was wondering what to expect.
Thanks |

Its talking about the shutter not the frames per second. Increase frames per second and then play at standard 24/30 fps creates slow motion. Most video cameras have a shutter speed of 1/30 to 1/60 second, but can cause bluring with faster movements. You can created a faux slow motion clip in a movie editor such as permire, but it won't have the quality of true slow motion.
I took a memory card to best buy and played with the new Casio Exilim EX-FH20 high speed camera until they asked me to stop (I was kicking & throwing camera bags;-). The supe HS 1600 frames per second was crappy quality, but 420fps down looked good, and you can go from standard 30fps to 210fps within a clip which is cool. |

So even though the shutter is clicking at 1/1000, it is still only hitting at about 30fps (pics per sec). So even though each "frame" will be 1/1000 shutter speed, it will only take 30 shots per sec?
However, If I do take it at 1/1000 and then slow down to say 1/15 or 1/10 won't the result look a little better than the standard vid cam slowed down?
Also...on the Casio...I actually owned it for about a week. I got it to have an all in one still/video cam to take along where ever I go. I chose that one because of it's great slomo also. I returned in after a week because even though the slowmo at about 210 was usable, I found that you had to have LOTS of light. Indoor basketball, nighttime football was tried and the slomo vid was too dark for me to enjoy afterwards.
However, when I got that sucker out in daylight, the 210fps was unreal ! It was just like you see on the science shows !
Like you said the 1600 frames was postage size vid !
BTW...I got the cam from BH and their policy is less than 200 still pics and you can return in for full refund. I returned it and picked up the D90. I'll always buy from BH.

hmm.. were you able to adjust the iso for hi-speed modes ?
wonder what it would be like with a couple of halogen work lights ? |

If I recall, you were limited on the setting for high speed but I think when I pumped the iso high...the vid came out very grainy...and bad. I think I used it at 210fps at a high school football game. Lights were very bright but vid came out too dark to enjoy.
If I can dig up the vids, I'll post them later.

Right.

Like the casio you would just find that you need much more light. The only advantage the 1/1000 is that individual frames wouldn't be as blurry. Also we have a Panasonic VHS camcorder at work (I'm a AV tech) and if you leave the HS shutter on it looks very strange videoing normal activity. Evidently the human eye has an effective shutter speed of about 1/60sec , so conversations & such looks kinda weird.
