hello forumers,

i am wanting to get a camcorder for superish slo mo.
i would like to record at least at 720 and at at least 300fps.
is it possible to get a camera to do this for approx £200/£300?

or do i have to shell out much more or rent?

thankyou

1) What are you intending to film? - Is it a 1-off project?
2) what level of quality is necessary?
3) I rather doubt you'll get that level of slowmo even at 10x budget...... but then, I'm so often wrong.
4) You need to join a video(filming)-club to get pro-gear, unless you work for an established Broadcaster, for example.

i thought as much. can anyone prove 12harry wrong?
whats the deal with it being so expensive? does it require special internal gear to transfer high res to storage at those frame rates?

You could be looking for a camera that does 50p or 60p recording mode (with or without sound) and then conform this to 24/30p or 25p in the edit, this will give you a 50% slow down that looks natural. You won't find that for £200-£300.
Check out my latest video here where I used the AF101 24:60p mode for 50% slow down at 1080p resolution. Some consumer models also offer this type of facility along with some DSLRs that do 50p or 60p, usually at 720p.

If you want super slo-mo then you are looking at the likes of the Red Epic (£60k plus) that does 300fps at 2K or the Phantom Flex again at silly money, but superbly demonstrated here

Lastly you have some software options in the shape of Twixtor RE:Vision Effects, Inc. : Products: Twixtor which ranges from $330 for the standard plugin to $595 for the pro plug-in. It works with most higher end NLE editing programs and uses frame interpolation with correctly shot frame rates to give you super slo mo for little money (in comparison to the Epic and Flex).

Lastly, why so expensive? It takes a lot of storgae and processing power to get high definition images at such high frame rates and remember the faster the frame rate, the faster the glass (lens required) and higher shutter rates, all require high-end, well built equipment to get it right. It is not something a consumer product is likely to have (super slo mo) but 60p conformed is starting to appear at consumer levels, just not at the price you want it at, sorry.

You might be able to rent the cameras I mentioned (which are video cameras, there are also specific high frame rate cameras available for hire that would give you images up to 3,000 fps), but you would be looking at a lot more than your budget for a days use and insurance etc.
 
thanks phil. that answered alot for me. these plugins? do they take 50p or 60p footage? how much can they slow before it doesn't look good?

and have you heard of the sony 3 second slomo HD cameras? how do they fare? (i could break up shots into 3 second bits)
 
Sony did/does offer "Golf-Shot" (or similar name) if that's what you mean - but I doubt it's 3 sec and As I recall the frames are VGA, so quite small. Some cheap Fuji stills also did this....very high speed, but very small frames...worth a look, eh?


Those plug-ins will requie a fairly powerful PC (or Mac) to run. This needs to be factored-in, as well as the Editor software. However, I recall Vegas Studio (v10 £34 Amazon) will permit up to 1/3 speed and there are tricks like re-rendering to create extra interpolated frames - more or less what the plug-in will do. However your original footage needs to be good, if you have any chance with the outcome.

What is it that needs this ultra high speed?
Can you hint?


Phil Hinton:
Really impressive vid slow-mo, thanks .
+ Q about the text - Why do you need to "warm up the sensor" to reduce noise. Noise is a function of the absolute temperature so the cooler the less there is. Astrnomical photographers actually cool their kit to reduce noise.....is this warming more to do with condensation, perhaps? Or that cameramen work better in the warm, maybe?

It's more likely the computing power to do real time mpeg compression at the massive frame rates.

It's full 1920 x 1080 on my Sony camcorder but the burst time is just about long enough for a golf swing. It takes a second or two for the H264 encoder to clear the buffer and write to disc after the camera drops back to 25fps.
 
Looked at Sony website, but they say it's microphone determined (seems fair). But I haven't found the fps for the 22 frames they process. Do you know? -or- Have you done any speed tests?

EDIT: 5dn - you might need to sync a sound-source to trigger this feature . . . .

Which camera are you talking about :confused: There's no way to initiate recordings from a audio event with my Golf Swing equipped Sony Camcorder.

I need to identify which part of a clip is actual slow mo, I will find one and look in a editor.

Example clip

00083.MTS - 4shared.com - online file sharing and storage - download

It's not fast enough for what the OP want's. To capture that sort of action the shutter speed would have to be very short. As a result it needs intense lighting like you get from an electronic strobe and a very fast lens. Pro kit will store the footage uncompressed.

If anyone wants to look at the Sony Slow Mo I have uploaded a sequence of sequential frame snapshots (they include some water splashing).
