If you were thinking that HD Movies on the Xbox is impossible - you thought wrong. I made this post to make the advantage over DVD clear for interested people.
Here is a comparison of a few frames from I Robot encode I did.
- Top image is the NTSC DVD at 720x480, resized to 1920x816.
- Middle image is TS 1920x1080p NTSC reencoded as XviD at 1280x544 and resized to 1920x816.
- Bottom image is the TS used for 4XBMC* encode (middle image) at original size.
(Another comparison could be made at DVD resized to 1280x816 and compare to unaltered image from 4XBMC* XviD)
Faces, fire and water are usually complex to encode.
Original size (3.7 mb): I.Robot.png
Look at the detail here. The DVD is very blurred but the 4XBMC encode shows great detail.
Original size (5.4 mb): I.Robot2.png
As you can see the level of detail is much higher in the 4XBMC* XviD encode than the DVD - much closer to the original. This is very much visible running XBMC at 720p!
DVD Specs:
4.37 gb
720x480
AC3 5.1
MPEG2
4XBMC Specs:
4 gb (less than fatx limit!)
1280x720(544)
AC3 5.1
XviD
TS Specs:
13.7 gb
1920x1080
AC3 5.1
MPEG2
So if anyone is interrested I was thinking about doing a basic guide on how to do these 4XBMC XviD encodes from your recorded/downloaded Transport Streams.
* 4XBMC XviD is basicly some changes done to the XviD encode to allow HD content to be played back on the Xbox with no frame drops and stunning image quality. The changes to XviD codec was done by plugh, so credit where due!
