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.

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 pulldown (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 on 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.
