[QUOTE=jpp72;n442951]Unfortunately, this looks like an issue on your end and not a StreamFab issue. If you have replaced an libraries or python scripts, i suggest you do a full uninstall with Revo Uninstaller and reinstall cleanly.
If you don't want to buy a pro uninstaller, you can find it on pirate sites like filecr.com or appnee.com but make sure you use something like Sandboxie to run a keygen or loader in case there is a trojan in it.
No replaced libraries or scripts. To clarify - this only occurred when I tried to use settings other than the default settings. If after analysis I just hit download now, it worked fine in H264 at 1920x1080. When I tried H265, or DolbyVIsion or 4K version - that's when I got no video, just still image. AS also reporting no 4K version, only 1600x670
