Working on a 2 min project and after rendering (in either Magix or Sony AVC) I am seeing a random rendered stuttering of some parts of the project and then phantom glitches of video out of time within the rendered clip (kind of like a 1 sec insert of a clip in another part of the project randomly inserted in other parts of the final rendered video). Stuttering is not a factor of the playback device, something is going wrong in the render. Smart resample is turned off and I've tried GPU render both on and off. Files are being decoded with compoundplug.dll
Video is a mix of DJI drone 4K (Inspire 1 X5 and Mavic Pro), Canon DSLR (5DMkiii), and OSMO X3 footage. Source and render is 1080P 29.97fps.
Am running Win 10 64Bit ver 1709 build 16299.192, an Intel i5-6600K 3.50GHz CPU, 32GB RAM, and an AMD Radeon R9 200 series graphics card (software ver 17.7). OS is on a SSD, render and files are on a separate HHD.
