DivX Dropping Frames? But Why?

[Anakin]

Looking at the title, you would think I am on about capturing. I am not. I was watching a DivX I had converted from one of my DVD's on my PS3, there was a lot of jerky movement. So I look at the original DivX file using VirtualDub and noticed it wasn't the PS3 jumping, that was how it had been encoded. I set it at quantizer 4, and pretty much all default settings, yet every so often, jerky movement. Tried it both in VirtualDub and TMPGenc 4 Xpress. The source file doesn't have this problem, yet the outputted DivX is jumping in the same places. Anyone had this problem before? I am using codec version 6.8.5.

Thank you guys

We want information, Information, INFORMATION.

What did you use to to do the conversion? What settings beside quantizer=4 did you use? Was the source interlaced and if so what did you do about it? Was it 24 f/s converted to 25? Worse yet 30 to 25?

The codec is not the problem (unless there is a bug in that version), the process is. Four does seem a bit low to me but I used Xvid when I did h.263 and it wouldn't cause jerky movement in any case.

What do you mean by jerky? One stutter every 24 frames?

Interlaced 25fps > interlaced 25fps. I ticked the boxes Interlaced and TFF. Rewatching it, it seems to be just fast motion where frames are been dropped. I can understand this happening while playing, but why encode it that way too?

My understanding is that DivX and XviD are not well suited to interlaced encoding and although it is possible to do so it rarely works well.

I thought that too. I deinterlaced it (Blend in VDub) and the problem still occurs.

Found the problem. If I change it from Home to Unrestrained, it plays perfect. Dunno why but it does?
