MPEG-4 encoder settings 341

Max b-frames count
The maximum number of b-frames (view page 350). Several cases of application, e.g.
video conferences require "no b-frames" in order to achieve the shortest possible
reaction times during transfer.

Scene change detection

If this option is activated the scenes will be detected during encoding, thus allowing
you to insert an I frame (view page 348) after a scene change.

MPEG-4 simple
If MPEG-4 H.264 cannot be played back on your device, use MPEG-4 Simple.

Note: We recommend that only advanced users make adjustments to the advanced
settings. You can use the technical specifications of your playback device to help
with this.

MPEG-4 preset
Different presets located within the encoder.

(A)SP@L0-L5: (Advanced) Simple Profile in Level 0-5
(Q)CIF (Common Intermediate Format): CIF is a video format produced as soon as
1990 with the video compression format H.261. At that time, the format was used for
video telephone conferences.
The "Q" in QCIF stands for "Quarter", and since resolution is halved in terms of height
and width compared to CIF, the entire size is only a quarter of CIF.
QCIF was popular with mobile telephone manufacturers, since the resolution of 176 x
144 pixels was sensible for the first affordable SmartPhones (144 x 176).
(Half)D1: D1 corresponds with MPEG-2 DVD. HalfD1 has exactly half of the entire
number of pixels, meaning that the pixel number of the height and weight is 2/3 of D1.

720p: Video stream with a resolution of 1280 x 720p (progressive).

Apple iPod: Apple iPod-compatible stream.

Sony PSP: Sony PSP-compatibler stream.
