OT Help with picture size please.

[Budge]

Forgive my ignorance but I am stuck with a picture size problem with old
editions of Inspector Morse videos. These have been saved as .mp4
videos and are generally 4x3 format.

Given that my screen is a wide format screen I can accept that there
will be black margins each side of the screen but the picture does not
appear to be 4x3 but closer to square and if anything appears taller in
proportion ie slightly distorted.

I have played with most of the controls I can find to no avail and seek
help getting back to basics to find out if I am doing something wrong.
Any suggestions please.

If you play them on the PC (maybe you are doing that anyway) in a
window rather than full screen do they look right?

Hi Colin,
Actually playing on HDMI2 input of TV with Vero 4K player running Rpi
type of device. Tried other devices like Firestick and using NAS device
but always comes out very similar and approx square not even 4x3.
Still trying.

Are you able to play it on a PC with something like VLC? In a non-full
screen window so it should show the aspect ratio. Also you can look
at the video properties on the PC and see the resolution details.
Unless you can do that it is difficult to know whether it is the
display setup or the file.

The display aspect ration (DAR) may be being achieved with non-square
pixels, and it may be that your player will not handle them. The
relationship between the aspect ratios is explained here.
https://en.wikipedia.org/wiki/Pixel_aspect_ratio

ffprobe -i=<filename>
or the Windows version of mediainfo can be used to show the aspect
ratios. You can use ffmpeg to change the shape of the pixels. As far
as I know it is done by modifying the container without re-encoding, so
it should be fairly fast.

This article

particularly under the heading "Playback and editing of anamorphic
video" identifies some further obstacles to getting PAR and DAR right.

One solution may be to record them again from the ITV3 repeats. There
seem to be two a day at the moment.

Hi Richard,
I have done this with a couple that crept in as signed versions. Will
do some work with mediainfo when I have time but size seems the same so
not too old. Will get back to you when I have the info and take it from
there. Many thanks.

I cannot find anything wrong but since there are only a few videos I
need correcting I have just downloaded them again. Very strange but
something beyond me to fix. Regards.

What player are you using? Try VLC
