Skip detection for ripped DVD MKV/MP4

[jerrysmatrix]

I was wondering if there was such a program that anyone knows of to detect corrupted parts of a video. It occurred to me, that after I had ripped some DVDs, every once in a while there would be a few corrupted spots, caused by scratched in the disc. MakeMKV does a good job and stitching the videos together and making the video still playable, even when there are scratches on the disc that cause a skip. However, it doesn't warn me when there are scratches on a certain spot.

I the means to make flawless rips, which is what I intend to do. I find that the JFJ Easy Pro is great for fixing scratches, but it's becoming real time consuming and touchy to deal with. So I try to use it only when I really need to.

So is there any advice or software I can use to scan files/disc for skips or quality degradation in video?

Edit:
I ha been searching Google for video corruption/skip detection. Half way through writing this, I realized I should have been searching for DVD skip detection. Advice is still welcome though.

Any decent ripper will report errors when found, but it will take time to go thru all your disc collection, and even one 16X disc on a 16X drive takes 5-10 minutes.
To mass-check discs, you'll need a bunch of drives and a dedicated PC. Good way to save time while dusting off your collection.

If you want to check while watching, no player I know of can do that, and it would be nonsense as nobody will pay attention to tiny indicators while watching a movie. The only "players" that can halt or give detailed reports after watching are actually media rippers / testers / encoders with a big "monitoring window". Such tools are used by professionals and not intended to fully enjoy watching videos.

I find when getting DVDs from the library fast forwarding through VLC sometimes helps find the spot though an easier way would always be helpful.

I've been fast forwarding, and it does help, but it's very time consuming. I'm sitting on 30 DVDs right now that need to be returned soon. The only times that I get an error in MakeMKV/HandBrake, it turns out to be something unfixable, no matter how much I buff the disc or how shiny I get it.

Edit:
I've noticed that the unfixable discs, that manage to give me the errors, use some "stringray" rfid tag. I did a little research on it, and found that it has a really strong adhesive, and if they don't put those on right, there's a risk of bubbling and lifting data off the disc.

Now that's a shame; electronic tagging DVD's is a costly process and won't help the libraries much, I guess.

Try ripping with DVD Shrink instead (setting to NOT shrink) and use that file in MakeMKV.
DVD Shrink will retry sections giving you a hard time. If that fails, try cleaning the disc.

Just realised that no one is mentioning AnyDVD.

Basically, you can "rip" a DVD onto the hard drive, and not transoding, so, and the protections and the picture quality will be intact.

If you want, you can either watch the movie in VOBs, or you can transcode from there to whatever file format you want.
