To select I-frame-only MPEG recording
This uses less CPU, but requires 2 to 3 times the bit-rate, which
produces larger files.
1Click the I Frames Only button.
2Click Next> until you reach Finish, then click Finish.
To select I, B, P frame MPEG recording
This uses more CPU, but greatly reduces the bit-rate required
for a given level of video quality.
1In the Recording Wizard, set Number of P Frames in
Group to 12.
2Set Number of B Frames in Subgroup to 3.
(These are typical values; they can be adjusted.)
To record with a minimum number of dropped frames in
MPEG-1 or MPEG-2 format, the following settings are
recommended. Ranges are given, as some video compresses
better than others, depending on the amount of rapid motion and
the number of complex scenes.
