I have just started 'trying' to use DR this weekend just gone but not having much luck!, I have been using Nivida's ShadowPlay to capture game footage and then trying to use DR to edit this footage. The first file i tried to edit (which was approx 19GB large and mp4 format) i kept getting a 'Media Offline' message for the clip when i tried to add it to the timeline to edit, in fact when i tried to play the clip the preview window kept flipping between the 'media offline' icon and also a black display with green artifacts on it....
I have researched this error and a lot of people have suggested turning auto saving off (mine isn't on to start with) and also deleting the render cache, which i have tried with no luck!!
The 2nd file i have tried to edit was again an mp4 file and this time approx 12GB large, when i added this file to the timeline to edit, it would start to show preview screenshots along the timeline but then they would just turn to solid black, if i played the clip i could hear the audio but there was no video.
Any ideas what the issues could be here?
