It’s not built for chroma keying but would something like this pose any problems?

Thanks for the responses! I’d be prepared to buy red suits if I could find them! They don’t seem to exist…

Has anyone had experience using red suits in an outdoor setting? Would they clash with yellow colouring ? – ie. golden grass? Would hot pink be a better option? (Or would this introduce the same problem as lime of being too reflective?)

To explain the project further, I want to key out the silhouettes of humans so that I can animate their silhouettes with other imagery. I want to key out a distinctly human-shaped hole. In response to your point Dave, yes the figures will be moving behind other objects at times.

Also Dave, I’m not sure who told you Queensland was cloudy… but anyway, you make a very sensible point about shooting under clouds. If it weren’t for time constraints…

Thanks a lot for your reply Chris.

Blown out highlights on the suits is a big issue and I used luma keying with partial success. As can be seen in the stills, I found the green halo reflecting off the suit difficult to remove. I hope that by filtering the light and keeping the suit under 60IRE this halo will be eliminated.

One thing I don’t quite grasp is how a light meter can help me. Wouldn’t setting the zebras to 60 IRE give me all the information I need?

Shooting in the park was an ‘extreme situation’ I wanted to test. The actual location has some shrubbery but it’s not as green.

Another question: Has anyone ever chroma keyed underwater footage? I’m wondering how difficult it will be to key out lime green amongst aqua blue water.

Cheers!

Thanks guys,

though i haven’t lowered the bit rate yet i did switch several of the frame controls to best and the result is MUCH better. Thanks for the heads up on that one Michael.

All the best,
Sherwin

thanks guys. glad to hear it. now i can shoot in 60p and worry about this later.

Thanks Don and John,

Don, I know I can change to NTSC but that would cause further headaches in a PAL region country.

John, thanks for that. I guess 25p with 1/50 shutter is the best choice. I’ve also played around in the picture profiles, playing with all the levels and putting it on the cine3 gamma preset. Just wasn’t sure if I could do any better.

Cheers,
Sherwin

Thanks Chris – It’s a sad thing that watching HD footage on a DVD involves downconverting and then upconverting. I’ll play around more with the MPEG-2 compression settings in Compressor and see if I can get a cleaner image.

As for the effect of the DVD player itself, I won’t have access to the player so best ignore that problem, but it’s good to know for future reference.

Cheers,
Sherwin
