Is it safe to load used film again?

I'm rolling camera with b/w film at the moment.

If I want to use colour film for a moment ..
Is it safe to take b/w film out of the camera and load colour film..
and then use that b/w again..?

This is my first 8mm shooting.. and I think catrige prevent film from light.
Is it right?

Thanks..

Yes
"catridge prevent film from light". You are correct.

Make sure you have the correct exposure settings after you make the switch.

-Just remember that your footage counter will reset once a cartridge is removed, so you need to note the length of film left before you do the swap.

Good point Bolexplusx. Write it on the cartridge.

Hi,

this is correct. However the film in the film gate will be exposed to light (unless you change the cartridge in a darkroom). Hence approx. 20-30 frames will be "overexposed". In most cases this really doesn't matter. But if you've shot single-frame, a title, ... or other scenes where you've counted frames orseconds, you'll probably miss these frames later on. Hence -in these cases- it's better to film your lens cap for 1s before and after changing the cart.

The funky part is that even if you do change the cartridge in the dark, the drive mechanism can swing up to a full revolution before it engages the cartridge and starts the film moving again. This means that the frame in the gate will be multiply exposed.

-all the more reason to roll a little "waste film" if what you are doing is frame for frame critical!

what would prevent the pulldown claw from advancing the film even if the drive mechanism isnt up to speed yet?

havent tried any of this, but it just sounds odd to me

Dunno!

I've just seen a frame multiply exposed when I tried this!
