Adding a watermark means reencoding. Reencoding means quality loss (although maybe not much). The only way to get what you want (short of making a huge lossless file) would be to add this watermark as a subtitle.
I don't add watermarks, I remove them. Defacing videos with watermarks and logos is a stupid idea.
You need to hire someone that will wrote such software for you - you can modify encoded data of video not video (data can be modified in spatial and time domain) usually this is how real watermarking/fingerprinting works.
If you must put a logo on your video and you are familiar with Avisynth, it allows multiple logos at different times and overlapping or not.
Script setup matching the above:
v1 = Directshowsource("C:\Users\Bud\Desktop\aCommercial HDCNVRTED.flv").ConvertToRGB32.Lanczosresize(854, 480) img1 = ImageSource("C:\Users\Bud\Desktop\TransparentBG.png", pixel_type="RGB32", fps=23.976, end=100).converttoRGB32.LanczosResize(100,70) clip1 = v1.trim(0, -10) ++ v1.trim(10, -90).Overlay(img1, 356, 48,Opacity=1.0, img1.ShowAlpha()) \ ++ v1.trim(100, 0) return clip1
The above image has a transparent background and the script has all necessary items to allow this.
