What causes rips to have trails?

[XMonarchY]

Some BD rips have motion trails, while others do not. I tested those rips with several decoders, media players, settings and even computers - they always have motion trails. Some have more than others, and some are completely un-watchable. They also happen on different TVs (SPVA, plasma), so they are not caused by slow response times. Its just bad rips, but they are not overly compressed, have a decent bitrate, and are about 8Gb in size for 1080p 90-120 minute video.

Is there a specific term for this effect? Is there a specific ripping software setting that causes this? Is there any way to compensate for that effect using some special renderer/decoder settings? Again, these trails are not caused by display devices, media players, decoders, renderers, and post processors.

I understand that the concept of "rip" has the common (and wrong) meaning of "rip and reencode". In this case it's pretty clear who or what the offender is.
Assuming you have yourself ripped the movies try change the "ripper" into a better one, like MakeMKV.

@XMonarchY

How did you create these rips?

[XMonarchY]

DVD/BDs I own were placed into my BD/DVD-RW drive one a time. Then I launched the latest and registered version of DVDFab Blu-Ray (very expensive software!). I use the generic/default profile to make legit rips for my HTPC library because I need to conserve HDD space and because placing a new BD each time I wish to watch a different film is tedious, which is something lazy people like me avoid if the situation allows. In this case, it does allow.

Seems logical then to follow Ghitulescu's advice to try a different ripper.

You could also show us a video sample of these "trails".

Where can I upload a clip sample? Do I need to provide a photo of the original DVD/BD I have or take any copyright precautions? What is a good tool to cut out a piece of .MKV movie file so you can see the trails? VirtualDub I guess..?

You can cut an MKV using this:

A small sample of around 50MB is OK under fair use. You can use mediafire.com or dropbox.com and then post the link here.
