Interlaced support
I want to start Using VC1 for what i heard is good Interlaced encoding support, but your tool is missing that option right now, and my HD footage from Sony HC3 is all interlaced... and so far it doesn't look that great encoded.... will your program have interlaced option soon? or is there a way for me to deinterlace the Mpeg2 before i encode?

vc-1 should be good for interlacing? actually i have never seen an interlaced vc-1 stream out in the wild and afaik it has been only recently added to vc-1 advanced profile. even m$ (offering the only vc-1 codec around) only released vc-1 advanced profile encoding some weeks ago (no idea if it already supports interlacing)
so all in all i heavily doubt vc-1 has been much tested with interlacing at all. you shouldnt believe the marketing...

I can send you an interlaced WVC1 sample, if you'd like. |

http://www.citizeninsomniac.com/vide...preproc_17.wmv Encoded with wmcmd.vbs (WME9) with this command line: cscript wmcmd.vbs -videoonly -input 720x480_29.97i_900f.avi -v_codec WVC1 -v_mode 2 -v_quality 88 -v_framerate 29.970 -v_type 2 -v_preproc 17 -output 480i30__codec_WVC1__mode_2__framerate_29.970__type_1__preproc_17.wmv If you play it back via VMR, the renderer will probably deinterlace the image on playback. If you want to see the interlaced lines, try opening it in Avisynth with DirectShowSource(). |

I did actually start to update WMNicEnc, but never got round to finishing it. So I up'd the unfinished version just now as it is very slightly better and has a couple of things people asked for. Maybe i'll get the motivation to update it more one day

@sisman: In my WMEnc, go to the Advanced Options, now hold your mouse over the combo/select box next to the words "Video Type" to see what the 5 options (0-4) mean. Alternatively read about it at: http://www.microsoft.com/windows/win...aspx#VideoType

For anyone curious about encoding interlaced video with wmcmd.vbs, note that you need to set both -v_type to a non-zero value, and -v_preproc to 16, 17 or 18. Last edited by zambelli; 9th August 2006 at 06:40. |

@zambelli: Thanks, must have missed your previous post. So is setting g_wszInterlacedCoding to TRUE on the IWMWriterAdvanced2 interface of the writer when VideoType!=0 enough to support it?
(or do I also have to SetProperty WM_SampleExtensionGUID_ContentType on the INSSBuffer3 to WM_CT_INTERLACED, WM_CT_BOTTOM_FIELD_FIRST, WM_CT_TOP_FIELD_FIRST, etc ? ) -Nic |

g_wszWMVCInterlacedCodingEnabled = TRUE and also set the mentioned data extension unit value to WM_CT_INTERLACED + WM_CT_BOTTOM_FIELD_FIRST or WM_CT_TOP_FIELD_FIRST. The article also says "Setting the g_wszWMVCInterlacedCodingEnabled property to TRUE, and then not sending any samples with the content-type data-unit extension attached can cause the encoder to crash. Only set the encoder for interlaced encoding if you have interlaced samples to deliver." So sounds like you always need to set both or otherwise the whole thing might blow up. Setting these values should take care of correct metadata and data extension units being set. Setting VideoType will ensure the codec is actually encoding the images correctly. |

Nic - One question I have - in the new version of your encoder, is the buffer size adjustment only for VC1, or does it work with WM9? That's the one big caveat I've had with the Nic encoder is that there's no way to adjust buffer size to reduce dropped frames in regular WM9 encodes.

Hi guys, does anybody can explain it or comment: "Windows Media Encoder Studio Edition Beta 1 supports only the WMV9 Advanced Profile codec. Note that this is a different codec than the WMV9 Advanced Profile codec that shipped with the Windows Media Format SDK 9.5. Specifically, the Studio Edition version uses the WVC1 FourCC code instead of WMVA, and requires a newer version of the decoder." It is written here : http://www.microsoft.com/windows/win...usingsehd.aspx
