![]() For instance, if your frame rate is 1/25 (PAL) and your shutter speed is 1/20. No, except possibly by using a manual frame rate and shutter speed settings that are materially slower than the 50hz flicker. You then use only the audio of one track and mute the other. If not, you can apply the layering approach, which means putting the same clips on a second track, with one or two frames of difference in the timing, and then set the transparency of each track at 50%. As stated, some editing tools have a de-flicker tool or plug-in. If video you shot has flicker, then post-production removal is the only option. So this requires some post-production work? Some editing packages have a de-flicker plug in, but one can do it manually too. If you search "video light flicker," you will find links to pages or videos that offer advice, which may or may not work. If electric current is 50hz in Sweden, then the LED lights may pulsate slightly at a rate that approximates the 25fps or 50fps speed of the camera. I guess this is an issue camera manufacturers will have to solve, since all light sources will be LED within a few years. How do I, or the camera, control exposure when I am using manual shutter speed?ĭoes anyone have any other idea how to eliminate LED flickering? What is a "normal" shutter speed for video? How do I know what shutter speed is used when recording video in auto setting? I tried the same with my other camera (the FZ1000) but there the flickering was a lot worse, regardless of framerate and shutter speed! Interesting. I guess this is because the shutter speed was matching the frame rate? At 1/60 it was still noticable, but I think OK for "normal shooting", now I was shooting directly at the light source. At really high speeds, the flickering was awful! Then it got better and better, and reached the least amount of flickering when set to 1/60. I have never shot with manual shutter before. Going to manual mode and choosing shutter speed was interesting. Clip was recorded with my Canon G7X with 1920x1080 at 60 fps, auto mode.Ĭhanging between PAL and NTSC did not have any effect. Little did I know this would ruin my home videos took a short clip the other day and the flickering was absolutely terrible. ![]() Glitch in the PLC firmware? Our logic is robust, but the process does latch on with the presence of 3 inputs until the process completes.Recently installed LED lights at home. Ground fault, possibly the potential of the PLC and all inputs could go low enough to cause a false positive on all inputs simultaneously, just a brief flicker of ~1ms ![]() Noise on the input wires, possibly the wire itself (1-10 feet stranded) acting as an antenna How likely is it for the PLC to see a false positive on the inputs? I can think of a few possibilities, but maybe some of you with more experience than myself could give me an idea how plausible? Or other possible causes? The process that's initiates will latch on until it's complete, so it's possible that a momentary flicker on these inputs would initiate the machine. The only way in the PLC program for that to happen is if the PLC is seeing two pushbutton inputs, and a prox input. We have a machine that has initiated movement inexplicably, without operator input.
