Burn to Disc (VCD, SVCD, DVD)
 Extended resolution -
Generates larger images (extended height). NTSC: 512; PAL: 608. Attention: extended resolution
is not conforming to DVD specs.
 Inverse Telecine (NTSC; with Avid Liquid Blue / Avid Liquid Chrome HD ; IPB Cap-
ture only) -
Inverse Telecine makes sense only in NTSC because it reverses a “trick” used when converting
from film (24 frames per second) to NTSC video (29.97 or 30 frames per second). In the process
known as “Telecine”, individual film images are duplicated at specific intervals so that the playing
time of the original film and video do not diverge too greatly. Inverse Telecine eliminates these
identical and therefore redundant images during compression and consequently saves space.
Quality and Speed
This feature lets you choose your preferred optimization of the encoding process: speed, storage space on
the medium or visual quality (
Avid Liquid Blue and Avid Liquid Chrome HD do not sup-
port the Quality <-> Speed selection in IPB Capture).
The bit rate also plays a role. You can select:
 Optimal (fast)
 Good (very fast)
 Standard (fastest)
This selection influences several encoding parameters. Between levels, encoding speed increases by
approximately factor 2 (or decreases, when going down).
To illustrate the interdependency of the three criteria - speed, storage, quality - it is possible to set up a
small matrix. Note that the user’s time (or patience...) and the available space on the medium are the
defining criteria, and the quality the result:
Storage media has Æ
User has... È
... small capacity
(bit rate <= 4 Mbit/s)
... medium capacity
(bit rate ~ 6 Mbit/s)
... large capacity
(bit rate >= 8 Mbit/s)
... little time
selection = Standard
draft quality decent quality good quality
... sufficient time
selection = Good
near decent quality decent quality good quality
... lots of time
selection = Optimal
decent quality good quality very good quality
