    Can anyone tell me what happens to video content when InDesign exports to an interactive PDF? Does the video get transcoded, compressed, or resampled?

    We are having issues where the video quality degrades significantly in the PDF. The original MOV or MP4 video is clear. The video embedded within the PDF is pixellated. If we change the PDF Flash content to play in a floating window, the video looks good again.

    The video's quality should not be changing dramatically unless you are scaling the content. Be sure to place the video at 100% size. If you have scaled the video up, the quality would suffer.

    James,

    I think you may be correct. Scaling the video up or down causes it to appear pixellated.

    For a PDF that will be a full screen presentation, we can't know what the page size and therefore the video size will be for playback. We can insert the video at 100% into InDesign or into Acrobat, but it gets scaled based on zoom percentage.

    Is it possible to pass a Flash parameter to the video or video player, ie scale=noscale?

    If you change the properties of the navigation controller in the media panel, you can prevent people from viewing your video full screen. This way the video will always be played at 100%.

    James, good thought. That preference would prevent the movie from playing in full screen. It would not prevent the PDF from being displayed at full screen. Or set the video display at 100% regardless of Acrobat's zoom setting or screen resolution.

    Say our PDF size is 1024px x 768px. We insert a video at actual size, say 720 x 480, in the center of the PDF. Then I change to full screen display on my 1680 x 1050 monitor. That video will be enlarged by 136% and look very pixelated.

    If we set the video to play in a floating window, it will always display at actual size and look good. But we can't set or control the position of the video window.

    I thought the technique of passing parameters to VideoPlayer.swf had potential. https://blogs.adobe.com/pdfdevj…..yer_p.html I could not get the parameter scale=noscale to work.

    Well, there really is not much more you can do that what you already have tried. If someone zooms in, it will get pixelated. This is true of Photos and Video too.
