ST.TM.E10076.3
With frame pictures a frame of a field 1 and field 2 is encoded as a single
unit. With field pictures each individual field of video is encoded as a single
unit, but must be followed or preceded by another field picture relating to
its matching field.
Table 4.40: Field/Frame Options
Selected Option Description
Fields Field based pictures.
Frames Frame based pictures.
Auto Automatically chooses the correct option on a frame by frame basis.
3:2 Pulldown Option
To access the 3:2 Pulldown option, press the 3:2 Pulldown softkey in the
Video Encoder Menu. This enables 3:2 pulld own (film) mode to be
switched On and Off.
NOTES…
1. This option is only available if a 525 line 29.97 Hz video source is selected.
2. VBI in Picture is not supported when 3:2 Pulldown is active.
3. 3:2 Pulldown is not valid for Very Low Delay and Mega Low Delay coding modes.
4. It is recommended to set this option to On.
The option should be switched on if the video material originated o n film
and has been converted from the 24 frames per second film rate to the
29.97 frames per second NTSC rate. This enables the Encoder to increase
the video compression by only including a flag in the transport stream to
represent a repeated field (when detected), rather than compressing the
repeated fields.
Concatenation Option
NOTES…
1. Auto Concatenation is only available when software option M2/ESO2/ACON is purchased.
2. Concatenation is only available if the video source is SDI.
Use this option if the signal has been coded, then decoded and is about to
be coded again. It reduces picture degradation associated with multiple
generation compression encoding. Setting this option may give better
results as it tries to line up the I-frames . Only available to video via the
SDI input. See Application Note, ST.AN.1110, Near Loss-less MPEG
Concatenation Without Helper Signals.
