Those are some great ideas, Tony; I read the articles on aspect ratio (my head still hurts) but there is some hope of getting what I'm after. Jamie's suggestion to make a custom profile was great--it will take some time to test. I did make a test file at 320x240 but the output file was a .M2TS file that me FLV codec wouldn't process. I have a bit more research to do, but as you mentioned Tony, a better understanding of what I'm trying to do might make it easier to suggest a solution:
My AVCHD Sony Cam uses 720x480 format. I have used that format by first making an .AVI file then make a streaming video with my FLV converter. I set the player size to 720x480 and all is well.....except it's BIG and meant more for broadband use than DSL (my target).
(Take a look at:http://www.stonebrook-golf.com/chippingvideo.htm
I'm working on a website and I don't have the room on the page for a player that large--o I want to drop to something like 320x240 (smaller player on the page and more accessible to users. At the same time, I'd like to keep the highest resolution possible so it's not too grainy. Tall order, Huh? But that's the nutshell of what I'm trying to accomplish.
I might experiment with leaving the format alone (720x480) and just set the player code on the page to 320x240 and see what happens.
Many thanks for the suggestions to date.
