Yeah I noticed at the end my trails were too long.. I can fix that.. thanks for the advice. Um.. In regards to how I did it.
well I used a big blue screen 20 feet wide 7 feet high.
Use a DV cam of course.. preferably a XLs or GL1
um.. soem good lighting.
then use Adobe after effects 5+ <-- preferred
Use Ultimatte <-- if you can get your hands on it.
then composite it together.
and for those who said I used Pinnacle for the composite..
actually I used pinnacle for the compression.
*** BLUE screen.
I bought soem cheap fabric from WALMART to make the screen.
make sure it's pure blue and doesn't cast a reflection or wrinkle up too easily.
you can USE green if you'd like.. I prefer green, but the lady at the store said "we ain't got green.. so run along little boy" hehe..
Then most importantly.. make sure you get the right amount of light. try to balance the light out.
Also as tip. try to use the screen outside for a omnilight.. hence the SUN.
