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.
