    Artifacts around text when viewing a Jpeg image on a HDTV?

    iRuss Community Member

      I'm new to this kind of advertising media. So bare with me. I'm creating these 1920 x 1080 @ 96dpi Photoshop images that has black text on white background that are viewed on a LCD HDTV. The images are saved out as Jpegs at the highest quality setting. When I view the image on the HDTV, I see all kinds of artifacts around text. (See attached image sample that I shot with a digital camera of the HDTV screen.) Let me add that I do not see any of the artifacts around the text  when I view the Jpeg image on my computer's monitor.

       

      So is this something inherit to this kind of media? Or I'm I missing a setting somewhere? It would be nice if I could diminish the artifacts to a lesser amount at least.

       

      Thanks,

          That's the nature of JPEG compression, even at the highest quality level.

           

          The HD TV obviously magnifies the artifacts.

           

          I know nothing about TV or video, I just avoid the JPEG format at all costs myself, unless someone or something absolutely demands a JPEG from me, in which case I only generate the abomination as the final output file.  Try working with PNG files instead—if your intended application permits it.

            PNG won't work. Jpeg image is want they want and the only format that will work. They run 15 advertising images off a thumb drive. They run a slide show on the HDTV. The images stay up for 15 seconds at a time. Probably not enough time for people in a waiting room to notice the artifacts. Thanks,

              I agree, and it's why I do not use JPEG, unless the client's needs absolutely dictate it.

               

              I do a lot of Image work (tons of Titles) in PS, that goes to both DVD-Video and BD (Blu-ray Disc), and never, never introduce JPEG into the workflow. Everything that I output is PSD (or maybe a very few PNG's).

               

              However, from the last response from iRuss, PSD will not be an option either.

               

              As a bit of an after thought, perhaps iRuss could produce a Premiere Pro (or Elements) AV file for the SlideShow and Titles, and put an H.264 in an MP4 "wrapper" file on the thumbdrive? Then, a PSD could be used effectively in the video.

               

              Just thinking here,
