FFmpeg messes up image overlay's width after adding it to a video
I'm using the following command to overlay a given image onto a video:
ffmpeg -y
-i "Input.mp4"
-loop 1 -t 17 -i "overlay.png"
-filter_complex
"[1:v]fade=in:st=3:d=1:alpha=1,
fade=out:st=10:d=1:alpha=1
[ovr1];
[0][ovr1] overlay=(W-w)/2:H-h-10"
-codec:a copy
"Output.mp4"
The command works but it results in an overlay with a width different than the input overlay.png, it has the same height, though.
Here's overlay.png:
And here's how it appears in the video after FFmpeg overlaying:
overlay.png size is 274x79, but in the video it becomes about 324x79.
I've checked this question (ffmpeg overlay size) which suggest the use of scale, I changed the command to the following:
ffmpeg -y
-i "Input.mp4"
-loop 1 -t 17 -i "overlay.png"
-filter_complex
"[1:v]scale=274:79
fade=in:st=3:d=1:alpha=1,
fade=out:st=10:d=1:alpha=1
[ovr1];
[0][ovr1] overlay=(W-w)/2:H-h-10"
-codec:a copy
"Output.mp4"
But the results are still the same (bigger width), and I was able to confirm that scale does indeed work by editing it to scale=400:400 to check its effect.
What caused this and how can I keep the original size of overlay.png after overlaying it onto the video?
Edit:
ffmpeg -i Input.mp4 shows the following:

Your video is 720x480 but with a 16:9 display ratio, basically a widescreen SD NTSC video.
You'll need to make it a square pixel video before overlaying the image, using the scale and setsar filter.
So,
ffmpeg -y
-i "Input.mp4"
-loop 1 -t 17 -i "overlay.png"
-filter_complex
"[0:v]scale=2*trunc(iw*sar/2):ih,setsar=1[0v];
[1:v]fade=in:st=3:d=1:alpha=1,
fade=out:st=10:d=1:alpha=1[ovr1];
[0v][ovr1] overlay=(W-w)/2:H-h-10"
-codec:a copy
"Output.mp4"
