Till now I export my Premiere Elements 15 projects to the preset HD1080.
For most of my projects the resulting mp4 is OK but for some, when playing I through my Chromecast to TV the music track, and only the music track, faulters, seems to 'hesitate'. The videotracks are OK, including the sound going with them. When I recode using VidCoder to another mp4, everything is OK.
I tried reducing / increasing the the framerate, bitrate, comparing lenght etc... . I encountered the problem with for the moment 3 files, while
a lot of other projects rendered without a problem. Support chat told me there is a difference with the encoding of the music track, the codec in which Elements is exporting the file is not compatible with Chromecast. If so I should have problems with each of the projects.
I suspect the music track with the new feature of altering the lenght of the music being the cause of the problem, which should be an issue for Adobe.
