Hi Daniel

Another query

Ok so you use lots of images with no problems.
What’s the difference with your set-up?
What are you doing that I am not?

I have completed a lot of tests today and the only common thing I have found is that VS does not like images inserted as ‘Keep Aspect Ratio’

So do you have your ‘image re-sampling’ option as ‘Fit to Project Size’???????? or ‘Keep aspect Ratio’??????

When I use ‘Fit to Project Size’ I appear have no problems, so far.

I always use keep ratio, for a good reason, my pictures are scanned from 24*36 film and are thus not 4/3 originally.

Just a maybe silly suggestion; we all understand this is coming from the lines interlacing vs. MPEG encoding and the related subtle variations.
What if you ALLOWED variations (not asking quality 100% but say 80) maybe the litlle leeway will allow the encoder to get closer results on consecutive fields? What if you LOWER the bitrate to have LESS details in the output. Would the error bits be discarded?

(I remember in my VS8 time I had scrolling images problems while I always had rock-steady output before with Showbiz, to the point I was doing my travel maps in Showbiz and imported the MPG into VS8.
Come to think of it I think besides another encode, Showbiz was limited to 6000kbps.)

Another suggestion: don't forget to activate the PAL/NTSC filter. If you got 24 bit camera (or like me scanned) photos they use everything from color 0 up to 255. The encoder should get rid of the out-of-range colors, thus more processing, more approximations. Either use Photoshop to get rid of the extra colors, I never do, just activate VS' filter.

Sorry but I can just say I don't have problems and don't understand why others do. I have absolutely nothing particular and VS, DMF or WS2 all work OK. Maybe it's the player too...

Daniel, what are the pixel sizes of the images that you import to video studio?

Well the mileage vary since I crop them each more or less after scan,
but those where I keep 100% are nominally about 1800*2700 or 4.5MP.
