[Blu-ray] Dialog Box

r

[Basic Settings] tab

[Video settings]

[Profile]

Set the profile. The selectable profiles will differ dependent on the frame size to be exported.

[Bit Rate Type]

[CBR] assigns a constant number of bits. Although noise, etc. may be present, the encoding

process is made quicker.

[VBR] changes the assigned bitrate according to the complexity of the movement or image

quality. Compared with [CBR], the media volume can be used more efficiently, and this enables

more consistent image quality overall.

[Average ]

Set this item if [CBR] or [VBR] has been selected as the bitrate type. You can either select from

the list or enter values directly.

[Max]

Set this item if [VBR] has been selected as the bitrate type. You can either select from the list

or enter values directly.

[Quality]

Set this item if [Quality] has been selected as the bitrate type. Select the image quality from the

list.

[Use Hardware Encoder]

Check this item to output video using hardware encoding such as Quick Sync Video. It is not be

and output is with 5.1ch - 1ch:L, 2ch:R, 3ch:C, 4ch:LFE, 5ch:Ls, and 6ch:Rs. If the number

of audio channels in the project settings is 5ch or lower, all except 1/2ch are discarded and

output is with 2ch.

f

For [Linear PCM]
If the number of audio channels in the project settings is 8ch, output is with 8ch; if the

number is 6ch/7ch, output is with 6ch; if the number is 4ch/5ch, output is with 4ch: and if the

number is 3ch, output is with 2ch.

[Bit Rate]

Select a bitrate from the list.

r

[Extended Settings] tab

[IDR Interval]

Enter the IDR frame interval, and set the GOP size.

[B Frame]

Set the number of B-frames included in one GOP.

[Number of Reference Frames]

Set up to how many frames to consider when motion estimation is performed.

[Multi Slice]

Check this item to divide 1 frame into 4 parts. If the decoder supports multi-slicing, the

decoding may be made quicker.

[Entropy Coding Mode]

Select the H.264 encoding mode.

[Motion Estimation Precision]

Select the unit of division for the motion estimation block from the list.

[Minimum Block Size of Prediction]

Set the block size during motion estimation for intra-frames/inter-frames.
