Ghost Trail Help

Andy,

I'm sorry to have to tell you that this isn't an effect, its a composite. I'm doing exactly the same thing at the moment for a snowboard commercial. The compositors have rotoscoped the skater and isolated him from the background. They've then duplicated the roto-skater and overlayed him several times, each time nudging the start point along half a second so that he appears a little bit later than the skater in front.

This is done in after effects/shake/combustion and its a very time consuming process.
 
Check out the Hall of Time filter from Red Giant's Image Lounge collection of AE plug-ins. I am not sure, but it may help with what you are trying to do.
 
hi Richard
can this effect be done in Motion2 or does it have to be one those software that you mention
 
I honestly dont know if it can (I've never even opened it but don't tell anybody!!!). If it can, I know that it generally isn't. Programs like shake and combustion are designed as roto programs and make the process MUCH quicker and less painful. After effects is an average rotoscoper and I'd hazard a guess that motion is a bloody awful rotoscoper. For complex motion like these you will need a dozen or more masks (lower arm, upper arm, lower leg upper leg, skateboard and so on) all animated across the shot so its going to take a lot of tiime to do with a good program, with a bad one you probably won't get there at all.

Hi Richard,

Thanks very much for the info, I thought it looked a bit tricky! Great effect though!

Cheers,

Andy
