To import Samsung NX1 H.265 footage into After Effects CC flawlessly, an ultimate solution we found would be to convert H.265 to MPEG-2 for After Effects CC.
I got some H.265 videos from my Samsung NX1. Have shot some great moments with your Samsung NX1 camera and it is a pity to just throw them on the web for sharing. Why not beatify and polish the video by adding some special effects, finesse, a soundtrack or a tittle. All those work can be done perfectly with After Effects CC. As some guys suggest, to edit Samsung NX1 H.265 in After Effects CC, we need transcode H.265 to MPEG-2 for AE first.
