Hi Everyone, This is my first post on Cinematography.com but here goes... I am DPing a music video where I will need to create the effect of dollying out from the inside of a doll's house in a continuous shot. The camera will start inside one of the rooms and dolly out of the window, all the way out of the house to reveal the doll's house in full, within the frame. The main catch is that the doll's house will be set on fire from the inside out, so I need a lens that can "reach" far enough inside the house and then dolly out on a slider. I was thinking of achieving this effect with the Laowa 24mm f14 probe lens as it is the only optic that I can find which will keep the slider at a fair distance from the camera and be able to fit inside the doll's house. My main concern is that I will be shooting these scenes at dusk, I am worried the lenses aperture will be too restrictive. Yet I know this lens comes with LED lights on the end, so this might help. I can shoot on either the C300 Mkii or the Canon 5D MkIV with the current options available to me. (I am aware of the crop factor on the C300 as well). Would you guys think that this lens would be the correct choice for something like this? Also, what would be your recommendation for a good motorised slider with enough length to dolly out like this? I will get the chance to test next week but wanted to ask the forum first. I was hoping that a 24mm will not need to dolly back too far to see the doll's house in full. Thanks.
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. My search for a solution to a working version of v9.0 continues!
