Magix try find solution, they tested few options i send them crash report on zip file (hold ctrl+shift and "send" crash report) They answered:
"Hello, Thank you for your message. As a troubleshooting step, click Options > preferences > video tab, turn “GPU acceleration of video processing” to off, and set “dynamic RAM preview” to 0, click apply and OK. "
But it still crash (and turned off GPU is not a solution) if they help me i tell You all how to fix it.
@Excellentfilms At the moment, 'Bézier Masking' and the 'Video Stabilisation' is not using the GPU in the analysis (only the post processing in the preview and rendering). My question is what CPU do you use? The analysis is fully optimized but it needs (minimum) SSE2 and SSE3 support.
