Transferring Film to Tape

Transfer of 24-fps Film to PAL Video
If you use a PAL transfer, the film-to-video process takes place in two stages:
• Transfer the film to videotape by speeding up the film rate during the telecine process.
• Capture the transferred videotape into the Avid system at the sped-up rate.
There are two approaches to synchronizing sound, which are often referred to as PAL Method 1
and PAL Method 2.
PAL Method 1
With PAL Method 1, you synchronize sound with picture during the telecine process.
As with an NTSC film-to-tape transfer, the telecine process creates two video fields for each film
frame. However, because the film rate of 24 fps is close to the PAL video rate of 25 fps, most
PAL film-to-tape transfers involve simply speeding up the frame rate. This speedup changes the
frame rate from 24 to 25 (an increase of 4.1 percent). There is no pulldown that creates extra
fields.
n
Some PAL film-to-tape transfers use pulldown. This method is not currently supported in Avid
editing applications.
With PAL Method 1, there are two ways to sync sound with picture in the telecine process:
• Transfer the original sound recording to mag track, sync the mag track to the film work print,
and transfer both to videotape through a telecine process.
• Sync the original sound recordings to picture during the telecine process, and transfer both
to videotape.
In either case, the telecine process speeds up sound at the same rate as picture: 4.1 percent.
After you receive the PAL transfer tapes, the next step is capturing the footage in a 24p PAL
project. During the capturing process, your Avid editing application captures the material at the
PAL rate of 25 fps, capturing every picture frame. It stores the two video fields as a single
progressive frame, which you edit at 24 fps.
n
You must capture audio along with video at the PAL rate of 25 fps if you want to use audio that
was transferred along with picture during the telecine process. You set the Audio Transfer rate as
Video Rate (100+%) in the New Project dialog box. For more information, see “Audio Transfer
Options for 24p PAL Projects” on page 1506.
