Hi

This may be a really easy thing to do, however I've no idea how to do it

I have some videos which are in a 544x576 I think.

So this provides a tv picture which is full heigh but square so not using the whole horizontal space on the tv.

Is there a way I can upscale the video size ? Without loosing the quality. t present I run the video (a touch of frost) from a nas.
 
The only way to fill the screen is to either stretch it so everything in the picture will become fat, or zoom in, which will mean you have to chop off the top and bottom.

I'm guessing you're playing it straight on a TV, there should be a button which switches the picture mode between 4:3, 16:9, Zoom, Stretch, etc...
 
This maybe an anamporphic recording with non-square pixels - this gives some info on the strategy.
(eg. dvd's were 720x576, which is 4:3 but typically stretched to 16:9 screen)
when you look at the 544x576 with black bars at sides if objects./people seem compressed horizontally (eg a circle is a vertical ellipse) then it is anamorphic and it is correct/legtimate to expand it horizontally to 4:3 or 16:9,
maybe ffmpeg could re-code it at 1024x576 (16:9) for playing software that was unable to do it, on the fly, itself (I am pretty sure mpc-hc can)
 
If it's look evenly square (which 544x576 does) then it's probably displaying it 1:1 as the aspect ratio data is missing or can't be read. Something like Touch of Frost will probably be 4:3 so just set it to that with whatever device your using. The quality of the video will be dependent on anti-aliasing used.
 
Hi yea it's displayed correctly for the format it was filmed in. I just wanted to
See if I could upscale its resolution to make use of the size of my tv. But I can live with the black bars just curious really
