    Distortion of graphics files on broadcast

    Hello, we are recording 9-minute programmes, for a client, which are then broadcast on a satellite channel. Part of the content is full-screen graphics with details of holidays on offer. The graphics are created by the client, using Adobe Premier, and include some quite detailed/feint fonts and opaque text.

    The original file, played back from through our Tricaster 410, has minimal loss of definition on some of the smaller, feint fonts.

    But when broadcast the graphics become distorted to an unacceptable level.

    It's my guess that the graphics are simply too small for the TV screens,on which it is being received, to render them without distortion.

    What is the solution? My best bet is to suggest to the client that he uses much simpler and well-defined fonts in his graphics.

    Has anyone else experienced this, and what was the outcome?

    Thanks

    Is the broadcast at the same resolution you are using in the TriCaster? If not, make sure the produced graphics and TriCaster session all match.

    The compression of the broadcast might be where the text is falling apart. If that is the case, then going with a larger/simpler font would hopefully help.

    Thanks Kane, the broadcast is handled by a third party. I will seek to check that they are using the same resolution. We are recording with the settings: PAL, 1080i. The graphics being played into the recording are a mixture of .jpg and .png files. The file sizes average 1200kb for the .jpg files and 70kb for the .png files. In all cases, I believe they have been created in Adobe Illustrator.
