1st Ever Vdub problem

[wetodd]

I have always used Vdub for my encodes and never really had a problem with it until now. I am encoded (two pass, divx 5.02)with all my usual settings and the finished result is a pixelated (some nasty artifacts) and shakey encode. The video has an odd strobe effect sort of thing...and it's really crap.

I am wondering what's going on, if anyone can please help me out, I will appreciate it.


Thank you.

Could you give a bit more information? I don't think anyone can help with what you gave.
Most important:

Did you change anything on your system between 'it worked' and 'it doesnt work anymore'
how does your source look? perhaps this is your problem and your settings just don't fit this source.

[wetodd]

No, I haven't made any changes to the system itself. Especially not to anything affecting video/graphics and stuff like that. The source looks fine, I tested it a few times.
The outcome is an odd flicker, like A and B frames are trying to play at once.. it's like an extreme version of a movie shot on a low framerate. I think I may have solved it by going into the Video Menu, under Framerate and checking Reconstruct Fields Adaptive - (3:2 pulldown area).

Let me know if this give u any better info. Some guy posted a very similar problem in the Divx.com forum under the Encoding section, his username is Fledge.

Thanks ;)

Sounds like you have some sort of IVTC problem. Unfortunately I'm the wrong guy to ask about that (living in PAL country), so I cant help much.

If that works then fine. I encounter problems like that all the time with anime. Some of the material have undergone mutliple conversions (i.e. Film -> PAL -> NTSC). There are so many layers of problems that I need to abandon automated cleaning, and manually assist the process. I use Virtualdub to convert frames sequences to uncompress BMPs, fix up the bad frames in Microsoft Paint, derive replacement frames from existing frames using AVISynth and Virtualdub, create alternate frame sequences with AVISynth to assist spatial filters in cleaning up the bad frames, piece together the manually cleaned frame sequence using AVISynth, then encode with VirtualdubMod using minimal or no filters.

Sounds painful? Yes it is.

maybe wrong field-order? try switching it in codec settings
