Strange white line artifacts appearing in encoded videos

Hi, I'm new to this forum and have come here hoping to get some help with a very persistent issue I've been having in PowerDirector.

I keep getting these little white lines appearing in random areas of my videos. They look very similar to closed captioning lines. This problem happens during the encoding process, so they are being added by PowerDirector and are not in my source videos. What's strange is that every time I re-encode a video, they appear in either the same areas, or in other new areas, they are very random.

My source videos are almost always Xvid AVI videos that I then edit in PowerDirector, and output the videos to an MPEG 2 video using custom settings.

I'm attaching several screen caps of the videos & I have circled the white line artifacts where they appear. As well as a snapshot of the output settings I use to encode the videos to. I'm also including a Dxdiag report.

Thanks in advance for any help anybody might be able to provide. If there is anything else you would need from me to help identify this problem, just let me know.

Cory

Here is the Dxdiag report as well as a new snapshot of another example of the white line issue appearing in an interlaced video.

Those white dashes in your videos remind me of the noise generated on my analog svhs recordings years ago on a jvc which was never fixed despite head replacement among 6 trips to an authorized factory repair shop. I also remember those white or black dashes on analog recordings from an analog satelite receiver when the tuning is slightly off on a weak signal.

Since you said that they are not in your source video, I hope a senior contributor here might be able to offer a solution. Have you tried encoding without hardware acceleration yet.

His case reminded me what happened to me recently, that video was copied from VHS tape for table recorder.

In PD12 on the issue see the preview I cut all the mistakes I see, shows perfect after rendering showed many mistakes that I have not seen.

My thought that the Player can improve and reduce small errors in rendering PD12 not corrected.

In my case I made new edition of the video rendered in PD10.

It was a specific case VHS tape was very bad.

If this is your case, you should consider that your error is so small that it will be difficult to correct view, especially in the small preview window. AMD-FX 8350 / 8GB DDR3

... and with the computer you have - old dual core, Vista SP2, G33 chipset (latest drivers 2009). .

Tomasc & PlaySound, thank you for the useful replies :

No, I don't have hardware acceleration on during the encoding process. These artifacts appear to be getting worse and more frequent. I've done everything I could think of to fix this with no apparent solution. I should mention that both PowerDirector 11 & 12 are giving me the same issue. Additionally, I'm suddenly unable to output anything in MPEG 4 or Matroska. I'm stuck with only MPEG 2 (with white lines) or AVI.

I've recently began encoding my videos as AVI, and so far the white lines aren't present from what I could tell. So I'm convinced the problem is MPEG video related. Perhaps it's a codec problem? A missing/corrupt codec? Or some other setting related to MPEG that is causing PowerDirector to do this. I have the latest K-Lite codec pack installed & according to the Codec Tweak Tool, the Directshow filter "MPEG splitter (Elecard)" is broken/not correctly installed. I wasn't even aware I had this filter on my computer. Any thoughts?

Thanks again!

Playsound - The reason you didn't see all the problems when you try to edit out those white dashes in your video is because PD and all video editing software displays a field and not a frame for interlaced video on the timeline. I found that if only one vcr head is dirty, then it is possible to have all those white dashes on the odd or even field only. That makes it impossible to fix the video. It would always show on a crt tv.

cory - I don't use xvid, but vlc, if auto deinterlace is set to off, or set to display a frame, rather than a field then you may see those white dashes in the original interlaced video.

Let us know if this helps.
