Video Ghosting: Cause Vegas "resampling" setting

Lumix ZS3 (TZ7).
Note the unusual effects with speedy birds...a double image. If you stop frame it, you can see the wings at different positions! Will check with the Lumix DMC-ZS3 user forum at www.dpreviews.com (a great group...choose the Panasonic forum.
The cause was a setting choice (a default choice I guess and not obvious to see) set to Smart Resampling. Not so smart. Solution was to right click on each clip, then select "Disable Resampling." See similar video for result.

I am totally new to Sony Vegas Movie Studio Platinum 9. Am only at the level of bringing in clips and simple transitions, so did not try to make a real program.
I was intrigued with the abstract nature of the scene, with these fast birds, heavy shadows, the differences in exposure due to the extreme highlights of water reflection, etc. This shifing exposure was even more pronounced when I shot i the other direction, with a duck in and out of the bridge shadows, and the slight rapids giving jarring highlights.
I shot this footage with an underexposure of one notch (not the full -1)

You don't ever want any video editor (NLE) like Vegas to resample period.. unless in very certain conditions. Shut it off on all video editing. The last thing you want is the damn program to resample a video clip that has perfect capture resolution to begin with. I've used Vegas Pro for years now, and that was a horrible idea to make this setting default. Other than that. It's a solid program and thanks for the tip. :)

There's not even enough info in the tutorials or help section to let you know what it means, much less that you don't want it. I get rid of it on all clips now, and as Dave suggests above, there probably is a reason and I'll want it on some day.

GHOSTING PROBLEM SOLVED (see other similar video). Although this is probably related to an AVDHD format issue, some Vegas users suggesed to select "Disable resampling." This choice is found by Right Clicking on each clip, then choosing "Deselect Resampling." To see the difference, click on the pause button above at several locations in the video. You'll see a double image of the birds. Look at the other video, and voila...one bird only, sometimes very sharp! How about that, a solution!!

A poster on forum for panasonic cameras mentioned that AVCHD is not the best format for capturing quick moving subjects. So...I will return to the bridge and get similar footage and compare. I'm always amazed that there might be solutions to these sorts of problems...beyond the "what did you expect, it's a point and shoot camera!" Stay tuned.

I never knew about this. I'm going to sue it on my next vid

I was tearing my hair out wondering why slow motion looked so hideous and found out myself through trial and error that it is that horrible resampling which blurs my footage. It's nasty. After I figured it out I googled a bit and found you've obviously discovered the same thing. Talk about frustrating. It should be disabled by default I reckon. Finally I have a video that hasn't been tainted with resampling.

I agree, it annoys me too, StabbyMcButterPants.

That's the line between 24p and 30p.

[zesstyyy]

Exactly. Its almost like creating frames to fill in for the lost frames in a 30fps up-sample.

[zesstyyy]

Well of course it has some purposes.

Thanks for posting your example. The ghost artifacts are quite clear. I've got a new Lumix TS1 (FT1 on your side of the pond) and have some sports clips rendered using Sony AVC/AAC with the same ghosting issues. So I changed from the default "Smart Resampling" to "No Resampling" and the ghost artifacts disappeared. Not sure what I'll be doing when I try my hand at fast/slow motion - I assume there has to be some resampling to make that happen. Dave has a good theory there. Cheers!

Use a script and you can have vegas turn the smart re sample off for all the clips in one go.

My Canon HF10 footage doesn't suffer from this and that AVCHD as well.

If you look in to why Vegas does the re sampling i think it might be because the TZ7 seems to output files a 50P (twice the PAL rate). Smart resample is only supposed to do anything if the output rate is different form the original frame rate si i think it makes sence that its going form 50P to 25P.

Thats what i think anyway.

Dave.
