    4k jerky on HD-tv

    a_stoffer@ziggo.nl

      I made a movie with a Sony FDR AX33 in 4K format. After exporting it via Adobe Elements 14 into an PAL 25 fps 1920x1080 m2t-file it plays on my Panasonic HD-tv (100Hz, PAL very good when the camera is not panning. By moving the camera trees for example are displayed very stuttering (no frames stuttering). I found out that everything worked fine when I do not use 4K, but XVACS HD insteat with 50 frames per second. Anyone any idea how get everything smoothly played witg 4K footage?

          For tv try mp4.

          4K is 25p and 25p is a difficult framerate to pan with, and like trees very detailed picture.

          Either dont pan or pan very very very slooooooooooooow.

            It's probably the export to HD that's causing the stuttering.

             

            Which Export & Share preset are you using? It may be interlaced, which would cause the stuttering. Outputting as a 1920x1080 25p video rather than a 25i or 50i may solve the stuttering issue -- though you may need to create a custom output preset to do it.

              You write that you are outputting to a .m2t file.  I've been shooting and editing 4K footage from a Pansonic for a little over a year.  I don't have PrE 14.  In PrE 13 I've had very good results with Publish&Share > Computer > AVCHD > Presets -- MP4 - H.264 1920x1080p30.  In a PAL country, p25 would probably be better.   I've also had good results using XAVC-S to output at 4K for Vimeo (which now supports 4K).
