It depends what you are starting with . But in general you do not want the sar to match the dar . eg. For 1280x720, the DAR is 16:9, but the SAR is usually 1:1 (square pixel)
If the input is not square pixel, but is supposed to be, you can set the sar to 1:1 by using -vf setsar=sar=1/1
If it's something else you need to provide more info on the input
i am trying to get an image that literally is a raster image . it is literally 1280 x 720 with no stretched pixels. so where the images . so where the original image was 720 x 720 i want to render out the image as a bitmap to 1280 x 720 so that all the pixels are square. is thta possable? can ffmpeg do something like this.

If that 720x720 was not a typo , you would add 280 pixel borders to the left and right , assuming you want it centered

once again thanks
