I use a HP Z840 with 256 GB RAM, 2 CPU E5-2687W 0 3,10 GHz, NVIDIA Quadro K5200 and PPro latest Version, Windows 10. The project is stored on a SSD with 2 GB, free space 800 MB. The render files are stored on a SSD with 4 TB, free space 3,5 TB. Now the problem, I have a 42 Minutes Timeline with UHD clips from the Sony FS7 in XAVC-I. As result I must generate the whole timeline in XAVC-I for a Sony XAVC-I Player. In the new Version it is not possible, the Media Encoder crashed in the same Timeline after 8 Minutes, or 5 minutes, or 12 minutes and so on. When I tried to decode the whole timeline, I get direct the message E/A Error, this is German, it means I/O Error. The Output in h.264 or h.265 is possible without problems.
