High Speed Videography for Beginners.

Step 6 Further Questions

As this Instructable is largely biased toward someone who is already familiar with the camera, I might be missing some simple-yet-vital information; such as well, how do you turn the darn thing on? If you have read this guide and have any further questions, I will do my best to answer them here.

Here are a few preemptive questions and answers:

• What is the battery life?

Although I don't exactly wish to drain the battery of my camera and tell you how long it took, I can tell you that the camera will last one or two weeks without charge if it is turned off after use. Recharging only takes an hour if you are hasty, but I recommend leaving it there for a few hours to obtain a full charge.

• What is the recording time?

1,200 mode can record up to fifteen seconds of real time action before it begins to lose frames. Remember that fifteen seconds filmed at 1,200fps is an incredibly long time.
600 mode can record up to thirty-five seconds real time.
300 mode can record up to fifty seconds real time.
Here is an example of a full length 1200fps shot:

• How much memory can it hold?

It all depends on the memory card you use. This camera contains internal memory and a memory card. As I type this, I have 134 high speed videos and 227 pictures on a 2GB memory card.
A five second (real time) 300fps shot takes up ~8.9MB.
A five second (real time) 600fps shot takes up ~9.7MB.
A five second (real time) 1200fps shot takes up ~9.2 MB.

• Is there a special reason why the frame gets wider and wider as the rate goes up?

The narrower frame allows an increase in shutter speed because the shutter does not have to open and close as far in such a short amount of time. The shutter can only open so much in that very short period of time.

there isn't REALLY a shutter moving during filming, is there? i thought it was just images being saved one after another. Some video cameras don't have shutters!
