Video not centered and flicker between multiple videos



I am currently trying to play a playlist of videos through a vga cable. I am using an hd810. The videos appear to not be centered on the screen, with a black bar on the right of the screen and a lot of the left side of the video going off the screen. My playlist looks like this: videomode 1024x768x75p Viewmode 2 imagemode 2 video1.mpg video2.mpg video3.mpg Also, once one of the videos has finished playing, there is a very noticeable flicker before the next video plays. It does not go to black, it appears to shrink and expand the video very quickly. This could have something to do with video not being centered.

    Can you try doing this with brightauthor, if you have a pc? It's easier to set the viewmode settings for your video. You can set them to scale to fit or scale to fill. What's the actual resolution of the videos? Do you know what frame rate they are? Is the flickering you mention always present?

    I know if the frame rate and the refresh rate don't match up well, you can get flickering on the screen.

    I have now tried it with Bright Author and am still having the exact same problems. I have also tried the playlist_vga_demo. I have tried on multiple monitors of varying makes and sizes and multiple vga cables.

    My videos are 720 x 480 at 30 fps. I have also tried 1024 x 768, and 720 x 540 as well as 24 fps.

    In bright author I have tried both scale to fit and scale to fill, as well as scale to fill and crop.

    Neither of those settings you mention match well with 1024. At 1024, the refresh is 75hz coming from the brightsign. 25fps would look best. Did you re-encode these files, or take them straight off a dvd?

    Changing the frame rate to 25 did get rid of the glitch between clips.

    The image is still not centered though.

    The videos are animations made in after effects and exported out as mpeg2 files.

    In brightauthor, under zone properties, what's the setting for the viewmode. If you changed the setting under Edit, preferences, those are global settings that only apply to newly created projects. If you want to change the current project, you need to change the scaling settings under zone properties.

    Normally, if the spacing is off like that, it means the display is having a problem with the chosen resolution. Does your display have a menu where you can see what resolution it thinks it's current set to?

    Viewmode is scale to fill. This is under zone properties, not the Edit Preferences.

    No, the monitor it is currently hooked up to does not have any buttons on it.

    Just an update:

    I have continued to try different combinations of view modes and image modes and have not found any fix for the video not being centered.

    I have noticed that if I unplug the monitor after the roku has begun to play, then plug it back in, the video is centered. This is not a usable fix, but I think it might be clue as to what's going on.

    That definitely sounds like the display is having problems with the output from the brightsign. Does your display show you what resolution it think it's set to? IF so, does that match what you have set coming from the brightsign? Does the Display have dvi or hdmi input? I'm curious if you use hdmi out from the brightsign if you see the same problem.

    According to the supplier's website, the native resolution is 1024 x 768, which is the resolution coming from the brightsign.
    This is the exact model that I am using:

    No, there is no other input.
