I don't know if this has been observed before, but I thought I would share it with the PD8 community. I own a Samsung HMX-H105 HD camera, and for Christmas I bought my daughter and son-in-law a Sanyo Xacti VPS -HD1010. She just gave birth to our first grand child, and I took video shot from both cameras and built a project. The DVD version is fine, but the Blu Ray has a section where the screen goes black for one clip.

After a lot of experimentation, this is what I have found:

The black clip is always the first Sanyo clip after a Samsung clip. Transitions the other way work OK. The file type are H.264 MP4 for both, but the Sanyo clip properties are 59.xx fps, and the Samsung are 29.xx fps

To try and figure out what was happening, I built a simple short project and interleaved clips from each camera. The resulting Blu Ray disk played fine !!! I then realized the problem was the fade transition. It works from Sanyo clip to Samsung clip, but fails going from Samsung clip to Sanyo clip.

I am now rendering a new project where I inserted a black colorboard between the two clips with a short fade transition on either side of the color board. I will report the results tonight. mkh productions
