Tearing in Rips

[Calculon]

Hello -

I have a couple Blu-rays I bought and ripped. The problem I have with the Blu-rays is there's tearing, I think that's what it's called, where you can see lines in the video. I've ripped quite a few Blu-rays and run them through RipBot, but it's only these few discs that are having a problem. I don't see it when viewing the Blu-ray discs, but I can see it in either Media Player Classic or VLC. When I run it through RipBot, it does not seem to fix the problem. My question would be what's causing this and is there some way I can code it that fixes the problem? Thanks for any help.

If you are running them trough RipBot....then you are re-encoding the video to a lesser quality/smaller file sizes?

Tearing is a little hard to describe, but it's like when the image is bent. For example, the top part of the video may be distorted and bent. What you are describing seems to be an issue with interlaced video. You should probably name the specific videos you have this problem with as it might be possible to find out if they are interlaced. This is unusual for BluRay, but possible. And if you only see this problem with extras and not the main movie, we need to know that as extras are more likely to be interlaced than the movie. Finally, it would be helpful to describe your output settings in RipBot as you may be using something that is causing this.

Thank you for the replies. Yes, it does sound more like an interlacing issue. I can see it in the .m2ts file as well as the output for RipBot. Originally, I thought maybe it was the ripping software so I tried another, but it produced the same result. Specifically, the Blu-rays are the BBC Frozen Planet and Nature's Most Amazing Events. I have Planet Earth and Life too. I have no issues with Planet Earth, but every once in a while I see the interlacing with Life.

I take it that when you play the Blu-Rays on your player to the TV set you don't see any interlacing? So it's only after converting using Handbrake? Are you resizing them down, by chance? Are they being reencoded as interlaced? The BBC docus are 1080i and not 1080p, and you have to make sure you reencode them as interlaced. I don't use Handbrake and have no idea how to tell it to set the interlaced flag, but maybe you do. And don't blindly resize to 1280x720, if that's what you're doing. It has to be done in an interlace-aware manner.

Handbrake doesn't support interlaced encoding with x264. You have to use the manual command line options:

Or deinterlace before resizing and encoding. But Handbrake doesn't have great deinterlacers. And it doesn't have any double frame rate deinterlacers so you'll lose half the fluidity.

That is correct, when I play them on my Blu-ray player, I have no issues with them, but I can see the interlacing effect in the .m2ts files after I've ripped them before I encode them, though I've only used RipBot. Is there some way I can deinterlace the .m2ts file? Thanks for any help.

[manono]

Sure. Just turn on a deinterlacer. It has several choices, none of them all that good, but you may find them useful:

You don't see the problem when playing the Blu-Ray because your player or TV set deinterlaces it.

Thanks manono. I've never used Handbrake for encoding, only RipBot, but I did find the de-interlacing settings in RipBot using the arrow. It did seem to fix the interlacing in the picture, but the playback wasn't smooth in the preview. I'm hoping the file turns out better. The encode time looks very long, like seven hours. I hope the resulting file isn't huge.

I went back and reread the thread. I don't know where I got the idea you were using Handbrake. If you're already familiar with Ripbot and have found the deinterlacing settings, then you should be good to go. Yeah, nothing like encoding high definition material to make you wish you had the fastest computer available. Good luck.

Frozen Planet was released in 1080i H.264 video. I'm too lazy to look up Nature's Most Amazing Events but it's probably the same.

Yes, the resulting file after I found the deinterlacing settings looks great.

Funny you should mention the fastest computer available. I just bought an Optiplex 7010 with the i7-3770. My present PC has a Phenom II x6 and usually does an encode between 3-4 hours depending on the particulars. When I got the Optiplex and set it up, I happened to have a BD rip on my secondary drive that I had just done on my Phenom. The Phenom did the job in about 3:25 while the i7 came in around 2:10. While that's definitely faster, I'm not sure whether it's worth spending money on. Had it been like an hour, perhaps so. I got a really good deal on the Optiplex so I ended up flipping it on eBay and putting a few bucks in my pocket.

Thanks all. I appreciate the help.
