Maximum bit rate (kbps): This is the maximum bit rate for the video stream, i.e. the
maximum number of bits the decoder is allowed to transfer per second. This
parameter only takes effect in the "Variable" bit rate mode.
Hardware acceleration: MAGIX Video Pro X6 supports the hardware acceleration
"Quick Sync Video" for AVCHD exports, AVCHD and Blu-ray discs. This can
noticeably speed up the encoding process.
Smart Copy: If this option is activated, unedited AVCHD material with hard cuts is
transferred without changes. This drastically accelerates the encoding process. The
transfer always takes place on the GOP borders is not frame-precise.
Maximum GOP length: The maximum GOP (view page 372) length is determined
here. High val
ues mean improved compression. Lower values create stronger security
protection and enable improved access to individual frames for processing the video.
B-Frame interval: Here you can specify after how many frames a B-Frame (view page
374) will be created. Several applications, e.g. video co
nferences, require a setting of
"0" for this, i.e. no B-Frames, in order to enable the shortest possible reaction times
for transfer.
B-frames save the differences between the current picture and the I or P frame
preceding and following. You only save the information that was not in the
preceding frame and not "left" in the next frame. Both directions are analyzed, hence
the "B" in the name which means "bidirectional-predicted".
Number of P-Frames: Here the number of P-frames per second is specified.
P-frames save only the difference between the current picture and the preceding I
frame (Intra Frames). The "P" comes from "prediction", which describes this
process.
HRD (Hypothetical Reference Decoder): When this option is activated, a virtual
decoder checks the data stream for compatibility with the video standard during the
encoding process. This ensures that the generated video is compatible with various
playback devices, but it also slows down the encoding process.
CPB (Coded Picture Buffer): This field is only unlocked when the parameter „HRD“
(Hypothetical Reference Decoder) is activated. The entered value determines the
buffer size for the HRD (Hypothetical Reference Decoder).
