Technical question Video Format
« on: September 17, 2012, 03:40:00 AM »
About the Red Dragon DVD (025192273629)

According to the cover and the back cover it is fullscreen, but... I just start watching it now and it doesn't look fullscreen to me at all :shrug:

If you check the capture I did the film isn't in a square wich is the way it always is when you minimize the PowerDVD window for a FS movie but a rectangle...

When I check the PowerDVD informations for the video attributes I got this

Video Attributes:
  Video compression mode: MPEG-2
  TV system: 525/60 (NTSC)
  Aspect Ratio: 16:9
  Display Mode: Only Letterbox
  Source picture resolution: 720x480 (525/60)
  Frame Rate: 30.00
  Source picture letterboxed: Not letterboxed
  Bitrate: 4.90Mbps

So is it really a Fullscreen presentation?

Could it be non-anamorphic widescreen? And maybe PowerDVD recogiyes the black stripes and therefore removesd them for you, creating the recangle?

The video atributes look like it should be fullscreen indeed.

You're probably right. It's the first time I felt on something like this, PowerDVD convert the image as a widescreen one itself. The fact it said 16:9 in the aspect ratio kind of confused me as this is anamorphic widescreen (fullscreen would be 4:3).

The lower screenshot is misleading because the entire image has a ratio of 3:2. I guess the screenshot tool had problems with the video material.

When you properly stretch it to 16:9 and then cut off the black bars, you'll get a picture-only aspect ratio of 2.342:1 -> 2.35:1

So it would be correct to say it's a widescreen presentation and not fullscreen since the FS ratio is 1:33 :shrug:

This is actually represented in the information Jimmy posted, the "Source picture resolution: 720x480", which is same to 3:2. Could be confidence :laugh: (I mean seriously, I am not 100% myself...)

I guess in this case the full screen only refers to image ratio sent to the TV (incl the black bars), not the actual film material.
