Issues using HEVC (H.265) videos embedded in FM 6 shows

I am struggling since trying to embed HEVC (H.265) videos in FM 6, the colors are displayed correctly in edit mode, but starting the presentation the colors become desaturated (i.e fade out). Videos done in AVC (H.264) mode are still working fine. Any similar experiences in our community and/or idea for the reason?

I’ve got the same problem with new videos in FotoMagico 6.4. After rendering the slide show the colors are also pale. Do you have a solution now?
My newer videos are in HEVC and the colors are pale. In Quicktime and VLC the colors are correct shown.

Hi Heartlakequeen, been with Peter from Boinx in touch but we`ve still got no solution for this issue. Workaround at the moment on my side, is to avoid using HEVC but instead gone back to H.264
