Sometimes this old archival material will produce flicker. If you work in news or a documentary environment there are always going to be times when you have to incorporate old file footage into your story. It sounds a bit like a parlour trick, but it’s more of a clever algorithm than magic.
#Problem with flicker premiere software
Flicker Free uses some clever software to smooth out the fluctuations to make the brightness consistent throughout the clip. The higher the frame rate you are shooting at, the more apparent it becomes. This flicker occurs because the AC can fluctuate in brightness as the electricity fluctuates (the ‘alternating’ in AC). A lot of these lights cause flicker when shooting slow-motion footage at 120fps or higher. These include certain fluorescent lights inside buildings, sporting venue, and even street lights. There are plenty of lights these days that are flicker free, but there are still a lot of situations where you will be shooting under lights that aren’t. When played back this exposure change shows up as a kind of flicker in your final result. The biggest problem with doing this is that the exposure tends to change between frames. 1min etc) and combining them to make a video. Time Lapse FootageĪ time-lapse video requires taking a photo or a video frame at set intervals (eg. Flicker Free can get rid of this very easily. Flicker is sometimes very obvious and easy to see, but if you happen to be shooting in say 25p 1/50th shutter in a country that is 60Hz, you can get flicker in your images that is not evident on your monitor or viewfinder at the time of shooting. Different types of flickerĪs I mentioned earlier, flicker can occur from a wide array of shooting scenarios. In my opinion, it doesn’t make any sense to apply it to your whole clip and then render it out only to find that the result wasn’t what you were after. If I was happy with the result I would then just apply the same effect to the rest of the clip. I found the best way to use it was to just apply it to a few seconds of a clip and then render it so I could see the results. Flicker Free doesn’t require any ‘pre-analysis’ to work. I use Flicker Free in FCP X and it’s just a simple case of dragging the effect onto a clip. So if adjusting the Time Radius and Type doesn’t solve your issues, try turning this off. However, with some footage, it can cause problems. Set between 5 and 20 for best results.įlicker Free will analyze the footage and try to account for fast moving elements in the scene. Only the Slow/Regular Motion – Alternate algorithm uses this parameter. However, it can result in more artefacts. This can produce much better de-flickering as each channel is processed independently. The Slow/Regular Motion algorithms are more appropriate for high frame rate video and footage shot at the normal 24/30 fps. Time Lapse is appropriate for footage shot over long intervals. The three different algorithms available in Flicker Free. The higher the value, the better it’ll remove flicker, but the longer the render times. For smaller areas, set to a low value.ĭetermines the number of frames over time that Flicker Free is looking at. If the flicker is affecting the whole frame, higher values are required. This affects how much of the image Flicker Free is looking at. If they don’t there are a number of parameters you can change to fine tune what the plug-in is doing.
#Problem with flicker premiere manual
And if you are like me, you only want to consult the manual if you have to (stupid, I know!) Digital Anarchy has made Flicker Free really easy to use and they provide a bunch of presets that a lot of times solve the problem straight away. Sometimes plug-ins can be complicated to understand and use. Flicker Free from Digital Anarchy was originally designed for de-flickering time-lapse shots, but the company actually found it worked really well for getting rid of flicker that occurs in many other forms. There is nothing worse than having nasty flicker on your images, and I think a lot of people are unaware that there are ways of reducing it, or in a lot of cases getting rid of it entirely. Now, this isn’t a new product, it’s actually been out for four years, but with more and more cameras now capable of shooting in high frame rates and capturing in-camera time-lapses, I thought it was a good time to look at it in more detail. It works in most video editing applications, such as Adobe After Effects, Premiere Pro, FCP X, Avid, Resolve and Vegas. Digital Anarchy’s Flicker Free is a plug-in that fixes flicker problems that occur from shooting time-lapse, slow-motion video, drone footage, or under certain LED or fluorescent lights.
