XviD + Nero = Upside Down VCD

[gr0x]

Hey Guys,

I am a lazy bastard. So lazy, in fact, that I sometimes use Nero to burn VCDs. Why? Its just too easy.

The other day I capped an ep of farscape in mpeg-2. I used VD to run it through the usual filters and encoded the result to XviD. A few days later I dumped the file into Nero. Nero had no problems with the mpeg encoding, and all that jazz.

One small problem- Nero encoded the source upside down! I'm assuming Nero used the XviD Dshow filter, and they aren't getting along so well. Any way I can fix this, so I can encode my XviD rips to VCD the lazy way? Can I force Nero into using a different dshow filter during encoding?

I'm using the XviD build from March 23rd. I'm gonna check Nic's and Koepi's pages now to see if a new build is available...

Well (I have no understanding of Nero) if your assumption is true, there is a switch in the DShow filter to flip the video. Try turning that on both using Nero, then that should work.

Also, try using AviC fourcc changer to change the fourc to DIVX & then let the DivX decoder do it.

(I built in the flipvideo function for just such an eventuality :) )

Thanks Nic- you rock. Will try it as soon as I'm done encoding the next few DVDs that came in the door. :P

A request- would it be possible to include the build date in the file name for upcoming XviD downloads? I've got about 5 builds and was stupid enough to put them in the same folder. :confused:

Cheers,

Hi,

did I get you right that you captured in XviD and then transcoded the file into MPEG1 (VCD)? In that case, of course, the XviD-DSF won't help you. :(

I capture in mpeg-2 @640x480 using a 9M bitrate, then converte to XviD using VD/AVISynth. One pass, quality based, slider @85. Filters and such to clean up my cable signal make the result better than the captured mpeg-2, and the quality is amazing. XviD rocks. I have yet to run over 350MB using these settings, and have captured numerous 44 minute episodes.

The reason I'm burning to VCD is I have a lazy friend with a lousy computer, and my captures are too high-res to run well on his box. So VCD is the solution. There is a quality penalty of course, but it's not that noticeable if you ask me. So to clarify, mpeg2->XviD->mpeg1 be the way of it.

I still haven't got a chance to mess around with this and actually try Nic's suggestions, but when exams are over and I've finished my battle with the new versions of Xmpeg I will do so and post here.

Nic, I'd suggest you to take a look at this article about upside-down problem in DirectShow filters (perhaps it's a bug in XviD DS).

Thanks for the article :) Interesting....

Because problems like this occur, I added the flipvideo option in the DSF, so if the problem does occur it can be rectified.

I don't believe it is the DSF causing the problem...But thanks for the article :)

Cheers,
