Hello, I'm relatively new to DV and recently installed version 9 after coming from 8.2. I've looked around on the net for problems regarding this issue and have basically hit a wall - the problems that most people have had were with the same anomaly I've been trying to deal with. Problems: Finalized file has a bar at the top of the video that flickers on and off. The entire frame will do this as well randomly throughout a clip. Along with the above, say I apply a LUT and grade it, then render. In the final file the video flickers back and forth between the graded footage and the stock footage. -- I haven't had any noise issues or anything of that sort, just random flickers -- Possible Solutions I've found and (or) attempted: Upgrade to the latest Cuda Drivers - 5.0.35 Disable SLI (tried rendering with 1 GPU and still had problem) Check frame rate to make sure the master matches the file Tried rendering as multiple filetypes Disable all audio * there might be some others but they don't come to mind right away, what I did find is that a lot of the macos users that had similar problems needed an OS update. ------------------------------------- The footage was shot on a 60D, 1080p @ 24fps as a .mov The media rendered, was rendered to a .mov along with a .#res file as well. I've included my project settings below - feel free to point out anything that seem obviously out of place ^_^ Along with that, here is a clip of the actual problem. NOTE: The flickering at the end of the video is not the candle. You can also observe the bar at the top of the frame that spans horizontally while flickering. http://lanelehman.com/V1-0001_MVI_9526.mp4 System Information: Operating System: Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120503-2030) Processor: Intel® Core i7-3930K CPU @ 3.20GHz (12 CPUs), ~4.2GHz Memory: 16384MB RAM DirectX Version: DirectX 11 Display Devices: Card name: NVIDIA GeForce GTX 560 Manufacturer: NVIDIA Chip type: GeForce GTX 560 Display Memory: 4050 MB Dedicated Memory: 978 MB Shared Memory: 3072 MB Current Mode: 1920 x 1080 (32 bit) (59Hz) Driver File Version: 9.18.0013.0694 (English) Driver Version: 22.214.171.1244 Card name: NVIDIA GeForce GTX 560 Manufacturer: NVIDIA Chip type: GeForce GTX 560 Display Memory: 4050 MB Dedicated Memory: 978 MB Shared Memory: 3072 MB Current Mode: 1920 x 1080 (32 bit) (59Hz) Driver File Version: 9.18.0013.0694 (English) Driver Version: 126.96.36.1994 Thanks for any replies I get here, I really appreciate the time taken to read all of this.
