Again Playout Images to TVS

Hi there,

from my Macbook i want to playout Images live to TVS (not as Media). I experimented some ways but i did not get good results. The images i played out to TVS are very chrispy in the live output of TVS.

My current setup:

• For playing out to TVS i currently use UltraStudio Monitor (set it to 1080i 50)
• For playing out Images i use "OnTheAir Video Express" (set to 1080i 50) which works fine with the UltraStudio Monitor
• The TVS is set to 1080i 50
• For capturing from the TVS i set the TVS capture settings to "Standard Progessive" and 100% for quality

The Images i playout to TVS are 1920px * 1080px. The output is very chrispy and it seems there is no way to get better results. Is there something wrong with my images? Do i have to be aware of something when i create the images in Photoshop? Or is there anything other causing these bad qualitiy output of stills?

I have attached the Image and the ourput MP4 Stream, so please have a look?

Thank you very much for any help!!
