Calculationconversion for 4:3 to 16:9

[jaloxaji]

Which calculationconversion should I use to convert the underneath films from 4:3 to 16:9. I have an advanced widescreen tv.

Movie 1: Avi (2 cd's)
Bitrate: 896
FPS: 23.976
Ratio 512 x 384 = 4:3 (1.33:1)[=4:3]
Sound: Dolby 5.1
Subs still have to be added


Movie 2: Mpg converted to Avi (2 cd's) with VirtualDubmod
Bitrate: 963
FPS: 25.000
Ratio: 480 x 576 (1:1.20) [=5:6]
Sound: Stereo
Subs still have to be added

(all values from GSpot)

Thx for helping me on this

Unfortunately I fail to see what this has to do with DV. Moved to "General Discussion".

I disagree!

This has anything to do with DV, because the final result has to be a dvd.

So I repeat the question:

quite franly you cant turn 4:3 into 16:9. you will either

a. have to resize which gives a real distored look, or
b. crop the image with which you lose a lot of information

the AR of the latter picture is not 5:6; you cannot calculate the AR from the resolution. judging from that resolution it was a PAL SVCD, which i think can be both (not sure though) 4:3 or 16:9. although, considering your question it is probably 4:3.

DV (or Digital Video) has nothing to do with DVD. Btw, no need to repeat your question, we can all read. Although, you should clarify them a bit:

1) I take it that you want to encode both clips to dvd (anamorphic)?

2) Is your second clip an avi or mpeg2? If it is an avi, does it play with correct aspect ratio (because 480x576 is a strange format for an avi)?

1.33:1 "fullscreen" sources gain nothing from being converted to anamorphic 16:9. Although, as stephanV says, the original DAR of the second one is unclear, as he also says, it's most likely 4:3, but I don't know from the information whether or not it's widescreen. But even if it is widescreen, it won't gain from being converted to anamorphic 16:9 either, as you can't gain resolution and detail if it's not there in the first place.

I'd suggest keeping them both at 4:3 and playing them on the widescreen TV with pillarbars (black bars on the right and left sides). Or use the zoom feature of your TV (if the second one is widescreen) to have it fill the screen. But it won't look so good, because of the original lack of resolution.

If the source is really 4:3, there's little that can be done without loosing (too) much content. If it has to be nonetheless, then a little cheating with SimpleResize's "WarpedResize" might help.

However ...

My usual Veto (http://forum.doom9.org/showthread.php?s=&postid=518035#518035).

Of course one cannot invent detail out of thin air (except for the special case of inpainting or related forms of artificial texture creation).
But I'd say it's perfectly possible to take what the source is giving, and make a better representation of what's actually there.
