Number of Passes
Select the number of passes to use for encoding from the drop-down list. 2-pass
encoding provides better quality but takes longer to encode.
VBR Quality
Sets the quality level for encoding. Higher values result in better video quality at the
expense of larger file size. This option is only available when Quality Based VBR is
selected as the Bitrate Mode.
Maximum Bitrate (kbps)
Sets the maximum bitrate for encoding. Higher values result in better video quality at
the expense of larger file size. This option is only available when Constrained VBR is
selected as the Bitrate Mode.
Target Global Settings
Enforce Fixed Frame Rate
The Windows Media Encoder will drop frames if the image quality would be very
low otherwise or insufficient bandwidth is available. This option forces the encoder
to always encode all frames, even if the image quality becomes very low because of
this.
Flexible Frame Duration
Enable this option to allow flexible frame durations in the output. Flexible frame
duration is most useful for video with freeze-frames and pauses since it allows a static
frame to span more than one frame of output.
Transcoding by WME
When enabled, the Windows Media Encoder Engine will perform all conversions such
as frame rate conversion, sample rate conversion, etc..
This will typically result in faster encoding and sometimes better quality especially for
multi-bitrate files.
This effectively disables certain built-in aspect ration corrections perfromed by the
transcodiing engine. You will have to ensure that the source and target aspect ratio
matches.
Deinterlacing/IVT by WME
Select the built-in de-interlace, de-interlace by WME or WME's inverse telecine.
