Using Adobe Premiere & Photoshop
to Rotoscope Digital Video
"Rotoscoping" is a method of animation that involves tracing film/video to achieve realistic results.
The
original rotoscope was a machine that projected
film onto a pane of glass,
where the animator
traced each frame by hand.
The
History of the Rotoscope
Max Fleischer invented this technique in 1915!
Step-by-Step Digital

1. Convert video into a filmstrip file using Premiere.
2. Rotoscope the filmstrip in Photoshop.
3. Import the finished filmstrip back to Premiere.
1.
Convert Video to Filmstrip using Adobe Premiere
The animation will be less smooth at 15 fps but a lower frame rate means
less rotoscope "
work per second"! |
Launch Premiere. Choose NTSC 640 x 480.
Import the video footage into Premiere.
PROJECT > PROJECT
SETTINGS> VIDEO
brings up this panel.
Change the frame rate to 15 fps.

IMPORTANT: ALWAYS save
the rotoscope file as a filmstrip!
ALWAYS make a DAILY back-up copy of the filmstrip, "just in case"
 |
FILE > SAVE AS brings up this dialog box.
SAVE
AS > Format: filmstrip.
The file should have .flm as its file extension.
Check "alpha channels" to preserve transparent areas
(created
with the magic wand or eraser tools).
ALWAYS
SAVE AS .flm
Files
saved as a .psd WILL NOT CONVERT back to video!!

3.
IMPORT the rotoscoped .flm file into Premiere
Premiere reads .flm files as video.
Add soundtrack, sound effects, transitions, video effects,
transparency
keys, titles to finish in Premiere.
Final Cut Express DOES NOT READ .flm files.
To finish the movie in Final Cut Express:
1. Import the .flm into Premiere.
2. Put the filmstrip onto the timeline.
3. FILE > EXPORT TIMELINE > MOVIE. SAVE as Quicktime.
4. Import the files into Final Cut Express.
