divx water mark on xvid encode with GK

[kremb]

I notice that there is a brief divx watermark on an xvid encode I have made. No big deal, it is very brief, I just don't know why it is there??

Also, I notice on the properties of my xvid avi that the video sample size is 12bit as opposed to some I have seen that are 24bit.

I'm just curious how this setting is changed and what it really means? and where would you alter that setting in Gordian Knot

It appears because you're re-encoding a DivX video into Xvid and DivX decoder is used (disable the DivX logo option in the DivX decoder).
Video sample size is always 12bit coz all mpeg4 codecs (xvid and divx included) works with YV12 colorspace. Often that value is not correctly reported.

vcirtual dub puts a different number there depending on which mode you use. "24" in full processing mode and "12" for fast recompress (IIRC, don't ask where the "16 bit" ones come from :))

The source is actually mpeg2, there is no DIVX anywhere in the assembly. It must hijack the xvid decoder or something. I'm on windows XP so I don't consider this TRUE xvid codec. Am I wrong? My xvid is keopi release. Would a DR.Divx install do this? I have AutoGK , Vidomi and GK too. sheesh.

Lots of learning. fun though.

Thanks for your replies.

Well, deactivate "Support Generic Mpeg-4" and set "Disable Logo" in the DivX decoder dialog.
For an unknown reason the DivX decoder is called somewhere in the directshow filter chain to decode something that's not mpeg-4...

ok most likely the video is not being encoded with a watermark and is simply being played back by the divx directshow filter. a simple fix is to deactivae Support Generic Mpeg-4.

[kremb]

correct, the video was not encoded with the watermark.

I reencoded the video to mpeg2 and all is well.

Thanks for the tip on disabling the logo.
