Ghosted Images on DVD but nowhere else

Richard Jones wrote on 2/16/2014, 3:30 AM

I've just completed a half hour project. All was well when I played it back on the PC and external monitor from the Vegas Timeline and all was well again when I rendered it out to MPEG2/AC3 (PAL in 4:3), transferred it to DVDA and played it again from Architect's Timeline. You can therefore imagine my surprise when I burnt a DVD from DVDA and played this back through a TV only to find that, in a number of random places, an earlier event( not the same one) was to be seen showing through the current one!

It was almost as though I had superimposed the events but there was no evidence of this to be seen in either the Vegas Pro or the DVDA project. I thought is might be a faulty disc but this same problem appeared when I went back to the project in Vegas and rendered out a small region which I then took through DVDA to record to another DVD.

The effect shows whether the DVD is played back to a TV or the PC! And a later project had been transferred to a DVD following the same procedure with no problems apparent

I just can't fathom out what has happened or what needs to be done too put it right. Any ideas or suggestions will be welcomed by this frustrated old man.

This has just got weirder!

In looking at the edit list as suggested by Bob I screwed up my layout display on the PC screen and reset it through Options > Preferences > Display. As I normally have the Timeline at the top of the screen rather than at its default at the bottom, I then moved it back to its normal place.

Guess what? I played a small part from the Timeline and the ghosts no longer appeared in the Preview set at Best Full so I rendered this same small section out again and burnt this to a DVD via DVDA and still no ghosting!

Hoping that this might somehow have resolved the issue, I previewed other parts of the Timeline and found that, although ghosting still shows itself at a number of places, there are now far fewer instances of this happening.

Does this offer up any ideas/possible solutions?

Yes I have a second video track where I've placed part of the titling and done a few masked corrections for faces etc. but the track is always clear above the troubled areas.

Just make a copy of your project file with a different name for testing purposes.

Just by Copy and Rename might also shake it loose too.

complete long shot here Richard, because i have no answer to this, do you have GPU turned on? maybe disable it. I say this because its sounding like a bug situation where by just moving your screen layout is having an effect on your actual media events. And being the weak point in the system, i'm calling GPU. Apologies for the lack of hard logic here! i know.

Ooh, I'm liking that Paul!

Paul may be leading us somewhere.

I tried disabling the Plug In (Unsharp Mask) on one of the areas where ghosting still shows (see my post re 'weirdness' above) and the ghosting disappeared only to reappear when I enabled Unsharp Mask again. I tried the same event using Sharpen instead and it was still OK which seems to suggest that there might be a problem with the Unsharp FX.

The GPU Acceleration is Off in Preferences > Video.

...there might be a problem with the Unsharp FX

Do you use the latest VP12 b770 ?

I'm just starting first project with this build, and have unsharp-mask added on some HDV source..., seems fine as long as I can see in Preview-Full quality, but maybe I (or other) can try check it out later...
*My GPU acceleration setting is ON

Yes I'm using the latest up-to-date version of Pro 12 but this is SD not HD. Do check via Preview > Best > Full for this as it doesn't seem to show on lesser quality previews.

Hi Richard, just tried out on a short 1m36s AVI DV clip. It is a looping background, as I have less SD 4:3 footages right now.

Add Unsharp-Mask > Extreme preset:
No issues found on GPU ON, and no issues too when GPU is OFF, Best Full, played normally.
Also render it to MPEG2 dvd template (2 pass), so far I don't find anything weird.

Probably other can try experiment with this...

That was very kind of you Set. Just seems to show that it's either me or my system where something has gone awry (almost certainly me I should think). Thank you.

You have a lot of people more knowledgeable than me helping you already, but I had something similar happen once several years ago when a title from the first 5 seconds of a program showed up "ghosting" throughout a program when rendered. See if any of these may apply to you:

1. I had been editing in multicam mode at one point in the project. I wondered if I had opened up an additional graphics pipeline that somehow wasn't being shut off.

2. I looked in my system error logs and found several messages to the effect that my graphics card was being overtaxed and I should run fewer programs simultaneously. (Vegas was the only program I had been running.)

3. Shut my system down, unplugged the power cord for a few minutes so every component would discharge completely.

Never occurred again. Never thought about it again till I read this thread.
