Description
B-frames
Specifies the maximum number of B-frames which have bidirectional prediction
for encoding in GOP. B-frames significantly enhance video encoding quality. Use
two B-frames for MPEG-2 and MPEG-4 ASP encoding and three B-frames for
H.264 encoding.
For MPEG-2, MPEG-4 ASP and AVC/H.264 video formats the following values are
available:
0 - 3
Frame Encoding Type
Selects the video frame encoding type.
For MPEG-2 video format the following modes are available:
•
Progressive
•
Interlaced (adaptive)
•
Interlaced
For MPEG-4 ASP video format the following modes are available:
•
Progressive
•
Interlaced
For AVC/H.264 video format the following modes are available:
•
Progressive
•
Interlaced
•
MBAFF (adaptive)
The
Progressive
mode is optimized for encoding of video that contains only
progressive frames. Use another mode for interlaced video. If interlaced
encoding is not acceptable, the interlaced video can be converted into
progressive format using the deinterlacing operation.
Interlaced video can be encoded using the
Interlaced
and
Interlaced
(adaptive)
modes. The first one is optimized for video that contains only
interlaced frames. Adaptive mode provides the better encoding quality for
interlaced and mixed (interlaced and progressive frames) video.
Aspect Ratio
Specifies the output video aspect ratio.
Speed/Quality
Allows the adjustment of the encoding speed/quality ratio. The
Fastest
mode is
adjusted to the maximum encoding speed. And vice versa, the
Highest
mode
provides the maximum quality. The optimal speed/quality ratio is provided with
the
Optimal
mode.
5.7 Picture Transformation
Click one of the transformation
buttons to open the
Picture
Transformation
group. It allows using such optional filters as: denoising, color correction,
deinterlacing, resizing, frame rate conversion, etc.
As in case with
Video Encoder Parameters
,
you can also apply individual settings for every track or apply the first track settings to all
available tracks in the file.
