Hi Mylenium. Here is system info asked:
-- Ae CS6 11.0.4.2
-- Windows 8.1 Intel i7 3630 2,4GHz 16Gb NVidia GTX 675MX 4Gb CUDA driver 6.5
-- Render settings: Best settings (default), H.264 (MP4) level 5,1 encoding VBR 1 pass, target and maximum bitrate = 6, everything is default (that is, RGB millions of colors premultiplied (matted)), audio output default (that is, 48000KHz, stereo, AAC hight quality bitrate 128
-- PNGs were obtained with Windows snipping tool (screen shots) - which never caused any trouble before.
-- The MP4 movie background was obtained with Camtasia - which never caused any trouble before.
Is there a hint of what can be causing that error and stopping the renderization? Thanks.
