View Full Version : Lens "Filters"??

I run a Chasecam 520 resolution bullit cam and PDR-100 in my racecar. My video on sunny days is VERY bright and the colors aren't represented well (mostly greens and reds?) - I was at the track this weekend, viewing someone else's video and it was AWESOME!!

I asked what setup they were using and it was the SAME setup as mine.

They suggested that I look into a UV filter setup.

Does Chasecam or another company offer something "turn key" for my bullit camera?

Is it possible I'm headed in the right direction with pursuing a filter setup? ...it makes sense to me but I'm not that edumakated with regards to video. :)

FWIW, my video has ALWAYS looked like this, whether I was using a Chasecam plugged into a mini-DV camera in a Pelican Box or using my recently acquired PDR-100...so it's apparent I should address this issue at the camera end - no?

FYI, I think the PDR-100 is the BEST THING since sliced bread, I wish I would've gotten ahold of one a long time ago...love it, especially with the lan-C button! :D

Hi

Sure a UV filter isn't going to change anything !
They stop the...UV. You perhaps need it, if the track was at the top of a mountain with a lot of snow. The photographer use UV or natural filter in front of there lenses, but their first utility is a protection of the first lens.

Before thinking that the cam could be is in question, some way of solutions :

- Is your set-up of the PDR on the max quality record ?

- Did you try after changing the font acrylic "filter" ?

- As the cam is full auto, in a sunny day, if you have more than 1/5 of the view "looking" the interior of the car, you are going to see a very bright track and if it's more than 1/5 of the view for the sky, it's the interior witch is going to be dark. This is the most important thing to understand to have a good quality.

- If you look at the video on a PC screen, beware of the screen set-up. Try to compare with a TV.

- In the old forum, there where some message from UK with colors problems in PAL. Sorry but I don't remember if they found a solution. The French Pal don't cause any problem.

Hope this message help you and good run.

Thanks Michel.

Trackrocket,

Try different mounting locations to see if anything changes. If not, if you can get us some sample video we may be able to offer suggestions. As a last step, if we can't resolve it in the field, you can send the setup to us for testing/repair.

Thanks.
