Video distortion/corruption

[W&B]

Testing 7062 full disc compression to BD25 1080P and I'm noticing some corruption in the video stream, it happens several times during playback on my PS3 but only for a split second.
The title's I'm testing is "Invictus" and "All About Steve" (I don't think it's related to any certain title). My graphics card is a NVidia GTS 250 with the latest driver 197.45...Win7 64x with a dual core 3.16ghz processor and 8 gb of ram.
My process is always ripping the BD to my HDD first and then using that as the source for compression...testing the original rip before compression is flawless.
I'm going to do another title but will disable the Cuda encoder and just let the software do all the work.

Please check both decoder and encoder, my guess is decoder's problem, please try software/DXVA/CUDA decoder to see the result.

Please note: "Invictus" video is VC1, and "All About Steve" video is AVC/MPEG-4.

compression errors

I also noticed a few corruptions (in other words: compression errors) in some movies. One is very popular. It appears in "Avatar" between 4:20 minutes and 4:30 minutes, when the spaceship lands on Pandora. The dust cloud (or hot air) under the spaceship gets torn up and pixelated, no matter which method you use. Software/DXVA/CUDA - no matter what, always pixel errors. Imho this effect is related to the very high bitstream speed - especially in this scene (up to 38 mbit/sec) which no "downsizer software" is able to handle. This error is reproducable, just compress the first 5% of Avatar and see for yourself.

Other movie, where errors occured:

"In the electric mist" - three errors, not reproduceable (compressing to DVD9-1080)

Compression problem... distorsion!

I, I have a little problem with a little BD disk movie like : It's complicated and The Final destination. I have made successfully : Avatar and spider-Man 3 ; i proceead like this : full 50gb on hard drive, after on the hard drive to another hard drive, compress full 50gb to 25gb! Everything fine!!!! Now with the other two (It's Complicated, The Final Destination) i proceed exactly like the other 2 but when it's time to compress, when i listen to the .m2ts file i see i little flick(image jump for half a second!) in the image every 5 or 6 seconds for all the movie!!! I can't change the video encoder! I Have try to remake spider-m an 3 to see if it's a configuration that i have changed... but everything ok!!!

Specs : dvdfab 7058, windows 7 ultimate 64 bit, ATI x1550 512mb (DDR 2 i think), asus p5q, intel core 2 duo e7400 2.8ghzx2, 4 gig ram 800mhz.

Help me please!!!

I made a BD-9/1080 of It's Complicated with no problems. Did you let DVDFab finish the scanning process before you clicked Start?

Thanks for that Fengtao, my card only supports Cuda for the decoder with VC1 so I just set it for software and left the encoder for software and Cuda...it turned out great. Thanks for the great proggy, keep up the good work Team Fab!!

Am having this problem also with The Hurt Locker. 4 distortions in 40 minutes. A couple of distortions looked to pixelate into another scene for 1 sec then pixelate back. Have this on DXVA and CUDA copies. Am in the process of trying a software only compress but it's twice as long so I will report back when it's done. Same pixelation/distortion is Precious also. Otherwise it looks fantastic.

[DharmaBummed69]

So far I can't get a successful copy with the software only of The Hurt Locker. At about 9 hours in it starts to have a I/O read error and won't go any further. Ignoring the error only causes another error message after it's dismissed. I was able to make a CoreAVC copy and compared it to the CUDA and DXVA copies. DXVA took the longest at 9h53m. Next was CUDA at 9h45m and fastest was CoreAVC at 8h53m. CUDA had the worst distortion with 3/4 to full sceen distorting for about a second per incident. DXVA only had bottom half of screen distort per incident and CorveAVC with the least distortion on the bottom 1/4 of screen for less than a second per incident. Most incidents seem to be fast moving pan shots but not always. Still noticabe on CoreAVC but far less than on the CUDA and DXVA copies. I'll try software only again but after 2 fails 9 hours in my heart isn't as much into it as before. Also all copies were made on Windows XP Pro 32-bit SP 3 but played on Vista Home Premium 32-bit SP2 as in XP all ISOs copies caused both PowerDVD 8 & 9 to crash. 9 would load the disc but crashed as it started to play the disc. 8 crashed as soon as the disc was detected. ISO's were mounted with DVDFAb VD and Daemon Tools with same results. ISO's play fine in PowerDVD 10 on Vista

So I tried throwing my HD 5770 into my XP rig. Can use DXVA to decode H.264 and VC-1. Used DXVA to decode and software to encode. Distortions still there. Would put it between DXVA version and the CoreAVC version although those both used CUDa and software to encode and this version was just software to encode. I haven't tried the new beta so I will try that tonight.

After trying 4 different methods of copying The Hurt Locker and watching the first 2 episodes on Weeds S3 D1 that I just finished compressing to BD 25 I have found that the distortions/corruption occurs around every 5 minutes but not every time. Weeds Episode 1 had distortion at 4m 57s then at 9m 55s. No distortion I could see around the 15m area then distortions at the 20m 3s and 24m 40s marks. Distortions are not exactly timed some occur in the 60 seconds before or after 5 minutes increment. Only exception has been Akira with a distortion at the 13m38s mark. Confirmed in all the BD50 to BD25 I've made. In copies made in Vista and XP. Started compressing about V7.0.5.8 I think.

Are you streaming these? if so, hit the select button while playing the files on the PS3 and then watch the bitrate as the distortion occurs. Let us know what you find.

[DharmaBummed69]

These are Full Disc BD50 to BD25. Creating a ISO to hard drive. Mounted and played on DVDFab VD and Daemon Tools with same results. Won't be burning until I recieve the BD-RE's I ordered. Will keep ISO's until I can burn them on physical media and verify stream corruption after burning. Have verified it on the 6 or 7 movies I've compressed to BD25 using 7.0.5.8(I think) to 7.0.6.2 Like I said it doesn't happen every 5 minutes but corruprions are generally around 5 min increments. Checking out the new version now. About an hour from a retry of Weeds S3 D1 on my XP computer being finished. Will post back after I review it if the distortion is still happening. Watching PowerDVD the bitrate for most of these movies fluxuates between the 8.0Mbps and 15.0 Mbps. Looks real good except for the corruptions every 5 minutes. By far better quality than the compressed HD signal I get on most channels now on DISH. After comparing I'm almost positive broadcasters are using similar compression rates as the BD50 to BD5 or BD 9. I can also see the difference on the USB hard drive I store shows on with DISH. When I moved the Real Time with Bill Mahers I had saved from when I first got this over 2 years ago, the files were 5-7GB apeice as the months rolled by the size of the files got smaller until now where the same 1 hour show takes up about 1.7GB

The OP clearly states that he is playing it on the PS3. If you are not then get your own thread.

Testing 7062 full disc compression to BD25 1080P and I'm noticing some corruption in the video stream, it happens several times during playback on my PS3 but only for a split second.

Really? I see testing 7062 full disc compression to BD25 1080p in the first sentence. Which is why I responded in this post. What are you seeing?
Because it doesn't seem to be the same as what I'm seeing. Either that or we are interpreting what he wrote differently than each other. I took it to mean that he was seeing corruption in the stream on Full Disc to BD25 copy he as playing in the PS3 Blu-Ray player. I could be wrong. I think I'm not as the only differnce is he's playing a burned disc and I'm using an ISO with DVDFab VD. So what? I have to waste a disc and play it on my PS3 for my input regarding this issue to valid? I'll do so but only if you agree to buy me a new BD-R after I waste it and it does the same thing on my PS3. If you are interested I monitor the bitrate during playback in PowerDVD 10 and I see not noticable difference in the bitrate. Of course it jumps quite a bit between 8.0Mbps and 15.0Mpbs so It's hard to tell if a change in bit rate is related to the corruption or just normal to the re-encoded bitrate.

WB you haven't chimed in since your initail post. Do you only see the corruption on your PS3 or does it happen on other blu-ray plaers also?

He may have had the same problem as you or he may not. You are still hijacking his thread which is frowned upon here. I didn't notice until later that you where not the OP.

Thanks for that Fengtao, my card only supports Cuda for the decoder with VC1 so I just set it for software and left the encoder for software and Cuda...it turned out great. Thanks for the great proggy, keep up the good work Team Fab!!

Looks like the problem was solved.
