Image *shaking* with CCE 2.62

p4t0z3u · 17th August 2003, 11:42

Hi everyone.

Here is a problem i've read on this forum before starting encoding with CCE but now, for my first encoding, the problem comes :]

Here's what happens. After an encoding (interlaced source encoded with CCE 2.62 4 passes VBR), the movie is like *shaking* in the static parts of scenes.
This is not the interlaced lines that i see (because CCE deinterlaced it very well).

Did you happen to have the same problem ?
The source is Interlaced PAL 720*576 VBR MPEG2 from my *Spirited away* DVD.
Thanks for the answers.

I think you're going to need to be a lot more descriptive of your problem before anyone can help. Shaking can mean about 50 different things.

You say it shakes in static parts of the scene. Do you mean sections of the video when there is little motion (still scenes, where the whole screen is like a stationary picture), are do you mean background (or foreground) areas where the is no motion in an otherwise active scene (no motion on the left 3rd of the screen, for example)? Or do you mean flat areas with little color variation?

By shaking, do you mean the whole picture is jumping up and down or side to side, or do you mean something more subtle? Is it jumping a lot (an inch), or just a little (one scan line)? Are the objects in the video jumping around, or just the colors (macroblock crawl)? Are they jumping in any kind of pattern (back and forth many times a second), or are they jumping randomly?

And probably the most important question: are you seeing the jumping on your PC screen, or are you only seeing it on your TV?

You are completely true Kedirekin. I wanted to cut a sample, but had to leave.

Here is a 10 second sample where you see and obvious example.

Thanks for helping me.

I do not have any jumping when playing the file with Power DVD.

I don't see any shaking in WnDVD either. But as the video is interlaced, you might want to read up on the CCE "upper field first" issue in the CCE FAQ, Q10.

does your decoder do any quantizer based post-processing? if so, then varying quantizers from b frames and such will cause stronger processing on lower quantizer frames... this "asymmetry" in the deblocking tends to cause shakes on my system. not sure about your video - i'm unable to download from here (my bastard ISP cuts my bandwidth after i reach a limit every month. i'm browsing with a cab;e modem at 28.8kbps grrr)

I had the same problem, before you delete your movie, install the newest WinDVD, or pop it in your DVD player...

peace
