Does DVDShrink lower bitrate?

[uNderdog_101]

I realise this might be a stupid question, but does transcoding a DVD through DVDShrink actually lower the bitrate? I have a DVD that's a little jerky when played on my player but works just fine in my PC, so I think the bitrate might be a bit high for my player, so I'm contemplating running it through DVDShrink to lower the bitrate, if that's what it does.

Yes. But I don't think the bitrate is the problem...is it a home burned dvd? could be some crappy media...

[uNderdog_101]

The media is just fine.

You can use Bitrate Viewer or MPEGProperties or similar to find what bitrate the DVD was encoded with. Unless it's above 9800Kbps, you may have other problems.

If the bit rate is too low, then you will see macro blocks at fast moving scences. It won't be jerky.

Did you even read the first post properly?

Yea I read it.

Jerky video on your TV can be caused by several things, most I can't begin to explain, but I will try to offer a few.

Wrong field order. If the field order is wrong in the video then the pans and action shots will appear to be jerky. Very noticable. Computers on the other hand uses progressive and the wrong field order won't show up.

Too many P frames. If the video has like 17 P frames (or a high number of them) then the pans and action scenes will look jerky. I don't know what the lower limit of smooth video concerning P frames is but 4 is about average, and 5 isn't that bad.

A capture of a jeryk source. I find many TV shows now days that the pans and action scenes appear jerky. Capturing such video results in jerky video regardless what you do. As Smurf says, "Garbage in - garbage out".

Low framerate or varable framerate. If this is the case then I don't see how it even plays on your settop box.

Some sort of converted video. That I don't doubt...

Oh yea, love the glasses.

Good luck

PAL players that convert NTSC on the fly can also produce jerky output.
