Hi

I'm not sure if this is the place to post this problem. I put together a very simple stop motion project inside a video. Very simply it was a pair of fins 'walking' across the deck of a boat,with the camera looking out to sea. The whole piece lasts approx. 6 seconds. I am using video package ULead8.

When I incorporated it into the finished video (about 20 minutes long) the sky looked like I had coloured it in with a yellow crayon! That is the best desciption I can give! There is no problem with the lighting on the photos themselves. I also tried to save the 6 seconds short as an AVI, which also showed the same problem although saving as a WMV is ok.

Initially I had each frame lasting 0.02 second which I then increased to 0.03 second but it made no difference.

Can anyone help? I have saved a clip of the video as a jpeg to illustrate this phenomenom, but not sure if I am able to post it in this forum

Please also confirm you have VideoStudio Version 8 (Quite old)
and not
MediaStudio Version 8.

Thank you for getting back to me. Here is the link to the still http://www.flickr.com/photos/35347592@N07/?saved=1

To confirm, yes I have VideoStudio Version 8 (very old but I am saving up for a biggie upgrade!)

That to me looks like a video card problem interpreting those particular shades fo blue.

It certainly looks weird.

Can you share with us your system specifications?

On close inspection it looks like 4 images superimposed on each other.
Bit hard to see what your source material is.
Can you explain in more detail.

Do you have a background Video and you are superimposing some stills on top, or superimposing a video on top. Please indicate which fins you are "moving".

I think what you are trying to achieve is the classic invisible man where a pair of fins mysteriously walk by themselves from point A to point B. If so and you are using still images to superimpose onto the video I would use a system like the Schindlers The Girl In The Red Coat but instead of monochrome I would be keeping the fins but deleting the remainder of the photograph using a suitable background colour that can be chroma keyed out.

Cleovo - my specifications are as follows

running XP SP3, intel core 2cpu at 2.4 GHz, 2 GB of RAM and 2 GB of virtual memory. The options for creating a Microsoft AVI file in Ulead 8 are
24 Bits, 720 x 576, 16:9, 25 fps
Lower Field First
DV Video Encoder -- type 2
PCM, 32.000 kHz, 16 Bit, Stereo.

THis is my first effort at stop motion so I am doing it very simply - the fins were each moved across the deck, no fancy superimposition techniques were used. I hasten to add here, I am primarily a videographer - this 6 second scene was part of a longer video.

Interestingly, I saved the whole piece as a WMV file and this artifact was not observed (see http://www.youtube.com/watch?v=u9VQzfs5 ... annel_page ) I also prepared the stopmotion footage in ULead 10 and saved it as an AVI file and again the artifact was not observed (I only have limited access to version 10 and cannot do the whole project in this version)

sjj1805 - there are 4 sets of fins walking. I'm not sure what you mean by source material I'm sorry.

Thankyou for your time

Thank you for the YouTube link and we can now see more clearly what you have been doing. Not quite what I thought - similar - but not exactly the same.

Clevo may have the answer - it could be your video card.
Please click here --> so that we can then view your system specifications.

This is a problem I have only seen in video games where certain shades of colour are masked or clipped (clipped as in not rendered).

The usual fix is to install latest drivers for your video card.

Hi

I have now updated my specifications - thanks for the tutorial link

Correct me if I am wrong but you have two video graphics cards?

Oh dear! Yes I do appear to have 2 video cards. It surprised me when I was collating the information requested! I don't know why there are 2 cards

Possibly you have a video card built into the motherboard and have installed a separate graphic card. To disable the built in graphic card restart your computer and watch the messages when the computer restarts - you are looking for "Press (this key) to enter setup"

You press they key indicated and this takes you to your computer BIOS
(Basic Input Output System) where you will find an option to disable "Onboard graphics"

Save the changes and restart the computer.
See if this cures your problem.

Many thanks for your advice. I have tried disabling each video card but the artifact persists. As I have managed to save the small section in ULead 10, I wonder if it is a 'bug' in ULead8 or there are different capture settings in ULead10. I have converted it to AVI file in 10 and thus will live with it - although if you have any other ideas I would be interested.

Thanks for all your help
