Expression Encoder 4 SDK输出文件质量差 [英] Expression Encoder 4 SDK output file with bad quality
问题描述
Hi
我已经尝试了来自...的微软表达式\编码器4 \ SDK \Samples \ WPFEncode \
并且注意到结果质量很差。
输入视频: http://tributecenter.s3.amazonaws.com/Export.mpeg
输出视频:http://thetributecenter.com/tributeplayer/default.aspx?webbideoID = 822#/ webplayerpage
示例:
具有相同输出设置的相同输入视频我尝试使用Expression Encoder 4 app并且结果不同。
预设: VC1512kDSLCBR
视频编码通过 Expression Encoder 4的大小: 1.41mb
使用sdk:1.48mb
可能需要调用一些附加方法或SDK上有错误?
您好,
WPFencode使用sdk的默认设置,没有应用预设。如果添加以下行:
mediaItem.ApplyPreset(Presets.VC1256kDSLCBR);
我希望这会有所帮助。

Hi
i have tried standard sample from ..\Microsoft Expression\Encoder 4\SDK\Samples\WPFEncode\
and noticed result is with bad quality.
input video: http://tributecenter.s3.amazonaws.com/Export.mpeg
output video: http://thetributecenter.com/tributeplayer/default.aspx?webvideoID=822#/webplayerpage
example:
the same input video with the same output setting i tried with Expression Encoder 4 app and result was different.
Preset: VC1512kDSLCBR
video encoded via Expression Encoder 4 has size: 1.41mb
using sdk: 1.48mb
maybe need call some addional methods or there are bugs on SDK?
Hello,
WPFencode uses default setting from the sdk, there are no presets applied. If you add the line:
mediaItem.ApplyPreset(Presets.VC1256kDSLCBR);
before job.Encode(); line, it will apply the same preset and you will get the same results.
I hope this helps.
