Light streaking In-car time lapses?

Hey, Just wondering what the best frame rate, shutter speed, exposure and all that stuff would be to film an in car time lapse so the light is very streaky outside the windows. I've seen this done but never needed to use it but now I must find out because I decided to incorporate it in a short film for one part. Anyways, any help would be awesome. Thanks.
 
can't really imagine what kinda shots you are tying to get?
any samples footage you can find on youtube or something?
 
The slowest shutter speed you can get, which defines frame rate. To get really good streaks you would need a different camera, but if you use 24P at whatever the slowest shutter speed is for that you'll get a little bit. Speeding it up in post might help exaggerate the effect. Also possible to add in post, which I assume would be normal on a high budget. I've only used it with still photography. Lenses that cause extra flare would also be good, but without an adapter you don't have that option.

[edit] That video is different than I was thinking, but the idea stands; you need long exposures. Longer than you can probably get going on your camera, as far as I know.
 
Okay so does anyone know how I could go about this in post? I use Final cut pro and would i need a plug-in or something? Thanks again :)
 
That was shot with a Canon 5D DSLR, with a slow shutter speed of probably something like 1/2 second, so there's a lot of light streaking and movement in that time.

The DVX's slowest shutter speed is 1/24 sec, you can get a little blur, but not like that.

You could try something in post like motion blur, but it's doubtful you can get streaks like with a DSLR.

Actually, in 30p the slowest shutter speed (using the Slow Shutter function on a DVX100A/B) is 1/4 sec. (1/6 sec. in 24p) and respective progressive frame rates of 2 and 3. For PAL cameras, the numbers are 1/3 sec and 1/6 sec with progressive frame rates of 1.5 and 3.

Depending on the ambient light levels and your speed, those shutter speeds should be plenty of time to obtain decent blur.

You're right about slow shutter. Thanks for the correction.
Probably still not as much blur as a DSLR, which could be 1 second exposure or more.
Definitely worth experimenting with though.
 
No question that there's not as much latitude as with a DSLR. I had no argument there. However, like I said, depending on the amount of ambient light and the speed of the vehicle, utilizing Slow Shutter could definitely have potential.

A quarter of a second is actually a pretty long time, allowing for plenty of blur; Certainly worth a few test drives.
