Flashing colours

[garybob]

I have tried this question in the Newbie forum, but as it is a conversion question here goes:

I have an avi file exported from Premiere using PICVideo. The avi is basically some high res stills with transitions in between. The avi plays fine in real player full screen without a problem.

The problem comes when I encode it to mpg format using TMPGEnc. After completion of the mpg file I play it and end with flashing colours. To try and explain, the sky is blue (Never!) but playing the mpg file results in differing shades of blue flashing on and off in blocks. The same goes for grass, again differing blocks of light and dark flashing on and off. The same is true for any area of colour.

I have tried to get the encoding done by nero at burn time, but this results in jumping of the pictures. Clouds in the sky tend to move, they jump left then right, I presume that this is something to do with the problem above.

Please someone help.

Dont really know I'm just fishing for info here?

This is a still effect but not really single stills? Many frames make up each individual "still". Framerate x display seconds should equal # of actual unique frame images. The encoder may be fooled by the fact that there is no motion (change between frames) while stills are displayed.
What is the frame size (rez) of the video images in the avi. You state hi rez!
Are they now 352x240 or 704x480. Is that a change. If you used any resizing in tmpg the least difference in the images would be accentuated during encoding.

Did you somehow change the framerate during conversion.

Is there an audio portion? Could you try to create the mpg without audio to see if its the culprit?

Thanks for the info.

The pictures are in the region of 1800x1200 from a digital camera. Using PICVideo codec from Premiere to reduce the resolution down to PAL VCD then use the PAL VCD template/wizard from TMPGEnc to get the mpg file.

I did enquire about reducing the resolution of the pictures in Photoshop but was advised against, in the newbie forum. I was advised that Premiere could do it on export.

I will try exporting to other reolutions. There is no audio.

Thanks

Further information that may help somebody.

This problem only occurs using MPEG-1. If I encode it using SVCD from TMPGEnc it plays fine. Unfortunately I can't then burn it to VCD.

Please somebody give me some clues.

Cheers,
