It would be easier if you keep it to one post on the same question.  Hopefully someone will be able to answer your question soon and if it requires a response from Stardock as to what kind of file is acceptable for a Dream you will probably need to wait until Monday for an answer.

Width should be 256, height is around 144 approx yours should be fine - it mainly is as a reult of the aspect ratio of the original video in the Dream, file size should be less than 2 Mb though.

Sometimes there are problems so I upload without the swf file then edit it later when accepted, at least in the old site you could do it that way without being sent back to moderation but with the new site I have not had to resort to that yet.

For some reason someone thinks you can create a working preview of a dream in a file size of less than 2mb. On small dreams it's possible, on a  larger dream, forget it.

While you can make a short one that does not loop, in my opinion it's a waste of time. I've seen some short preview videos lately that suck and do not show a good representation of the whole dream. Those do more harm than good and can actually cause a user to not download.

Up until the new site went live file size was never an issue, now it is. It needs to be changed back to a reasonable size limit. I would think that 25% of the dream file size wouldn't be too much to ask for, would it?

Frogboy, if you read this...what's your opinion?

 For all Carguy said; preview videos often too choppy, blurred, solarized and/or unlooped within present constraints.

iwas only able to include 30 seconds of a 4 minute dream...and i think it was 7 mb. (on the old site)

I may have done my flash wrong I dont know...but I wasnt impressed with flash at all and it leaks memory badly.(in or out of a browser)

You are right and I am sorry. I saw there was no replies and thought I had posted it in the wrong forum. I will delete the other one. Sorry for the inconvenience

Thank you to all for your input.
