rory 0 Posted February 23, 2006 So what do you think? Me, 640x480 comes out as a more normal size for playback than 720x480 which is more stetched. Rory Share this post Link to post Share on other sites
VST_Man 1 Posted February 23, 2006 BUT, I've noticed that when it is set higher I actually get more recorded/viewed pic. If you look at the sides of the pic it actually opens up a bit on the higher. I used 640x480 only becasue it is more a standard size than the higher. Share this post Link to post Share on other sites
solud 0 Posted March 17, 2006 640x480 looks better because it follows the 4:3 ratio. The presentation of the image is really the cause of the stretching, since all that would be required by the display medium would be to have it maintain the aspect ratio of 4:3 by stretching the image. 640/480 = 4/3 720/480 = 1/2 Standard television follows this format, as well as many other video signals. HDTV happens to be 16/9 (widescreen). -s- Share this post Link to post Share on other sites

The one thing I know for sure is that is is not 1/2. Welcome to the forum. Share this post Link to post Share on other sites
JMANOFNVS 0 Posted March 21, 2006 Hit the nail on the head!! Just like TV aspect Ratios. Wide screen can be 16/9, 3/1, 4/3, and many combinations depending on the different len's they used during filming/production, software used for editing, and whats gives the best end product. If the picture is distorted its because they didn't spend the extra bucks for the right equipment. Share this post Link to post Share on other sites
solud 0 Posted March 30, 2006 (edited) Good point. The 640x480 ratio is correct, but I believe the 720x480 is 16:9 and is scaled down to 4:3 at least from the prospective of a DVD. The one thing I know for sure is that is is not 1/2. Welcome to the forum. My mistake, I meant to type 1 1/2 as in 1.5. The number is the result of dividing 720 by 480 (1.5 or 3/2). 720/480 is not 16:9 (1.78~) but is rather 3/2. Edited March 30, 2006 by Guest Share this post Link to post Share on other sites
CollinR 0 Posted March 30, 2006 720x480 is anamorphic widescreen in 16:9 format. The pixel count doesn't add up because DVD players stretch it out horizontally. If you watch an anamorphic widescreen movie pixel perfect everything looks tall and skinny. The only thing I can think of is the encoder hardware (probably originally designed to capture TV) has the ability to capture it and so Geo passed it onto the application. Makes it handy to do a DVD comparison though I guess. EDIT: Reading material http://www.smr-home-theatre.org/anamorphic/Anamorphic.html Share this post Link to post Share on other sites
TopGeek 0 Posted April 2, 2006 Ratio's aside... in theory wouldn't 720x480 have "more detail" in given identical shots? 720x480 = 345600 pixels of data 640x480 = 307200 pixels of data as for how it "appears" - just used non-fixed aspect ratio and you can resize it to whatever shape tickles your fancy Share this post Link to post Share on other sites
