Video glitches using 'Create Disc'

I'm using the Create Disc feature to create Blue Ray 25GB, H.264, HD 1280 x 720/60p output. I've noticed that the m2ts files created during this process look great most of the time, but contain the occasional video glitch towards the top of the frame. I was able to isolate one of these glitches in the attached screen capture. I verified that the source video file did not contain the glitches, so it seems the re-encoding Powerdirector does during this process is adding the blips.

I've seen video glitching on my BluRay disks too. I've noticed this especial in stuff I've created useing the "canned" slide-show. These glitches did NOT appear when producing the same video to DVD.

My glitching was a bit different. It was more like macroblocking - horizontal lines - like a box of about about 1/3rd of the screen horizontally by (about) a tenth of the screen vertically.

I've seen that type of shift with some hardware encoders, did you by chance have it selected at the bottom of the "Burn in 2D" window? If so, you might try unselecting and see if you continue to have the issue. What is your source video resolution and bitrate?

I didn't have the hardware encoder option selected in the "Burn in 2D" window. I am using a Panasonic HC-X920 camera which is creating 1080/60p footage. After editing, I produced an H.264 file using the "AVC 1920 x 1080/60p (28 Mbps)" profile which used SVRT. I then used that edited file as the content for creating the disc.

After some additional experimentation, I believe some 'frame jumps' are being introduced during the "Produce" phase and then these 'frame jumps' are being converted to glitches during the "Create" phase. I will attempt to attached example footage of each of these phases. I'm also going to run a few tests bypassing SVRT - maybe that is causing the issues.

ngcard, how do you plan on using your finished BD, BD player and TV or computer or?

PD and BD structure not real friendly to 60p at 1920x1080. Some workarounds posted by jmone like http://forum.cyberlink.com/forum/posts/list/50/30115.page and many other posts.

If you are not up for that route I'd probably try the 1920x1080/60i, 24Mbps H.264 BD profile vs your current 1280x720/60p at only 16Mbps and then only use CPU encoding on the "Create Disc". No real need to create the intermediate edited profile with SVRT as that at times can introduce glitches too.

I searched for "Video Tearing" on the web and got lots of hits. It looks like tearing rather than a simple glitch. Some of them are related to the video card/chip.

By the way, are you seeing the tearing in the blu ray played on your computer or on a blu ray player (or both)?

How long are those video files? All we need is a couple of seconds. I have a pretty fast download speed and I gave up after about 5 minutes.

How about positng you dxdiag evaluation of your computer (part B) here:

BradG, Since you don't have the exact same issue of video tearing that the original poster is experiencing, perhaps you would get more direct help if you start your own thread. Thanks

Thanks for all the feedback. I did see the posts regarding enabling 1080/60p registry changes for creating blue ray. They seems to work well. I do understand that this format is experimental. I have a Windows media center PC connected to my TV which can play ISO files. So this is the goal I had in mind for playback. The test 1080/60p ISOs I created so far look great - except for this minor issue. I will try to post some shorter files or provide an alternate link. I will also look into the diagnostics you mentioned. PD13 | Win7x64 | 8GB RAM | Intel i7-870 | Intel 120GB SSD | WDC 320GB HD

I had glitches like this a while back. One issue was to do with the type of rendering I chose. If I used hardware acceleration it worked fine whereas rendering with just the CPU took longer (as you would expect) and it would get glitches similar to those you described.

One time I had to re-copy the original video file from my camera to my hard drive as one specific video file file had become corrupted and after rendering the picture quality was poor. Re-copying the original file over the corrupted one solved the problem.

Cheers,

Interesting. Skipping the "Produce" step and going straight to "Create Disc" does indeed provide video with no glitches. Thanks all. I think I have a workable solution. PD13 | Win7x64 | 8GB RAM | Intel i7-870 | Intel 120GB SSD | WDC 320GB HD
