The case of the lost pixels

[pdunn]

VS8 supplies AVI's for titles etc. I want to use one called 'the-end01.avi' which is like grains of sand falling to form the words 'the end'.

If I run this as a clip, it works fine, if I run it as a project, it loses some pixels - black squares appear and disappear. These are always in exacly the same places. It occurs in a test project, with no other video.

I thought it might just be that the s/w was taking short cuts to run in real time, but the task manager shows the CPU is never spending mroe than 25% on this task.

I tried rendering it, and the dropped pixels also appear in the mpg file.

Any suggestions ?

Could anyone replicate this problem, or is it my machine ?

Thanks,

Hi Peter

I cannot seem to find 'the-end01.avi' within VS 8 or anywhere on my pc.

Did you download the file as an extra from ulead, or is it supplied with the normal software.

If you can direct me to the location on my drive I will be happy to help.

Hi Trevor,

it's on the content CD of version 8, in video/3D video/The end-01.avi

Thanks,

Peter

I just replicated what you are seeing, as you said you only see it on the rendered video but i just ran the.avi through and they are on there but they are not able to be seen at full speed have a look at these frame numbers in the .avi version

frame 0:00:08 4 squares
frame 0:01:08 1 squares
frame 0:01:24 2 squares
frame 0:02:12 1 squares

Hmm - thanks. That's given me an idea for an overlay to get round it.

Hi Peter

Ok I have found the file, didn’t think of looking in the 3D video section.

I played the video using Power Dvd, Real Player, Windows Media Player and Quick time but could not see the ‘black squares’ you describe.

What I did see was an annoying pulsation of pixels within the text.
There were about 6 in all throughout the video.

When trying to play the clip in Video Studio the pulsation was still apparent.

Reducing the ‘Playback Speed’ to about 36% extended the duration to 8 seconds.
I preferred the slower approach.

I tried to render to Dvd Mpeg 2, I was not impressed with the results.

All the Best

Trevor,

yes, artifacts become apparent on rendering (but also when the AVI file is played in 'Project'mode.) You seem to be getting a variant on the problem - R U using VS9 ?

I think I can get round it with overlays though.

Hi Peter

I used VS 8 and 9 with the same results.
