Probably too late for you to catch this reply, but others might
verify it for future reference.
Since the video "looks vertically elongated," it sounds as if
all the data is in the frames but that the 16:9 flag was not
properly set during "format conversion."
I'm pretty sure that, when MPEG2 is in a VIDEO_TS set (DVD
files), you can use IFOEdit to simply change the 16:9 flag.
Beginner's tutorial:
http://www.dvdrdigest.com/articles/a...lag_page1.html
You should also be aware that the file can be played back on a
PC and many DVD players merely by setting the aspect options of
the player (this is the only valid use for any 16:9 display's
"stretch mode" which I've come across).
So, if you're planning to make a DVD from your MPEG(2) clips, go
ahead. If your "authoring" software does not offer you the
option to "change aspect ratio," and will NOT re-encode
regardless of your selections, then if the video is not
corrected "automatically" in the authoring process, use IFOEdit
afterward.
If there is a similar flag-setting freeware tool for MPEG(2) in
an MPG container, I've not found one in cursory searching. A
freeware hex editor, in the hands of one with knowledge of the
flag's location, would probably suffice? However, VideoReDo has
(and Womble probably has) a bit setting during output
specification, to change the aspect. Neither will re-encode for
this "fix," but at least VideoReDo will (and Womble may) quickly
rewrite the entire file. These programs are fee based, and may
be low-cost, depending upon your definition. I find VideoReDo
Plus indispensable; I've not yet needed its TVSuite version.
Regardless, there should be no need ever to re-encode for this
problem. That can only make things worse.
N.B. PGCedit is possibly another freeware candidate for
re-flagging IFO/VOB files.
