laser to mp4 file problem

[xenon1]

My problem is a strange one
using a laser disc that norml 4:3 format but the movie is in Letterbox ratio
now using a usb graber with Magix the picture and sound come on the screen and look normal the setup shows 720*480 29.9 sound ( also tried 640+480 )
but when the file is played back its way way streached width like a 16*9

power director finds the device and shows all is correct but no picture or sound
i sent them this but so far no joy

regards to all

You have to specify the Display Aspect Ratio (DAR) to 4:3.
If your videofile is x264 encoded, you can change this DAR setting without reencoding with MKVToolnix or clever FFmpeg-GUI or other programs.

mkv tools show the ratio greyed out ?

got it working but the converstion is the same after selecting 4*3
attached is a photo of the grab notice the length of the horses
the file shows 720*480 being 4:3
but some how the graber progrem sees the wide screen part of the frame and cant formt the correct ratio

Ok using 720*576 give the correct aspect ratio or close but the sound is 25 and this has to be 29.9
i hope that can shed a light on this one

according to this - https://www.magix.info/us/forum/can-t-capture-vhs-to-4-3--1221061/
720x576 is not strictly 4:3 - it is 5:4 AR

[xenon1]

that would do if the saound was good but its not
ok if magix is not workimng then why cany i get power director to even show the picture

[xenon1]

i fould a way to clean up the picture but its 3 process , now if only i can get a correct size to start with
any other program that will work and get me in mp4

I think the video must be cropped before encoding.
Cut a litte piece (30secs) of your video and post it here. So we can analyze it and give your the right settings.
You can cut it with g.e. Avidemux

croping the video wont help the over stretch

post a short clip from your original capture

720x576 at 25 fps is the international standard for capturing analog PAL video, for both 4:3 and 16:9 sources. It's also used on PAL DVD and SD Blu-ray. It just needs to be flagged and played properly.
