Premiere pro flicker removal

The big problem that comes with flickering is while shooting you won't find any flicker but right after shooting while reviewing the shots (Post productions), you will discover unwanted strobing effects in your shot videos.

In this article, we are going to learn various ways and solutions to handle flickering in your videos.

How to remove that nasty high shutter speed/ high frame rate artefact in your NLE. From Philip Bloom Reviews & Tutorials PRO. Featuring clips from 'The Man. This was done with Premiere CC but there is no reason why it shouldn't work in other NLEs. In your Premiere Pro Timeline, select the clip you want to move to After Effects. Right-click the clip and Replace with After Effects Composition. After Effects will open, giving you the option to save the new Project. Save the After Effects Project alongside the Premiere Pro one, so you can keep them together. Step 2: Add the Remove Grain Effect. Flicker can be removed in most cases by simply applying GBDeflicker's optimized default settings to your composition User-friendly interface makes navigation and processing simple for amateurs. Weird green flicker in Premiere? When I was editing this video in Premiere (Pro CC 2014), I noticed that some random flickers appeared - some of them green, some black, some white. This was only after I.

Part 1. What Does Video Flickering Mean?

In general, the brightness of every screen keeps changing continuously. Flickering happens when the change in the brightness of the video or screen is long enough to be noticed by the viewers.

Removal

What happens is that when you take one image from your camera the fluorescent light is at that time and while another time it is off. This phenomenon keeps going on when you shoot the video which gives you uneven or different lighting results even though your camera settings remain the same or identical.

Understanding the concept of lights

To understand the flickering concept deeply let's dive deep into its concept of lights. It is because flickering is all an issue of lack of light information (photons) captured/recorded by the camera. Unlike natural sunlight, which is constant, electronic lights that work on AC can cause flickering.

The power fluctuation is fast enough to not be noticed by human eyes. Hence, human eyes observe flickers. Moreover, Light flicker depends on the source of light, it is all about the light itself and the amps going into it.

Reasons for Video Flickering

Video flickering can be caused while recording in the following situations or conditions:

  • Due to Fluorescent Bulbs and Neon Lights

If you've ever filmed fluorescent bulbs or neon (artificial lights) lights then for sure you've noticed the most frustrating aspect of these lights to produce unwanted flicker in the footage. It usually happens due to your camera having different shutter frequency than the light source, or from the nature of the emitted light.

  • Due to Corrupted Video Source

Sometimes, even after shooting and reviewing the perfect shot/video can get flickers in it. Because your data source which is browsed by your device to execute or run your video files gets corrupted due to some anonymous reasons.

Now there is not always a single reason for it. It may be caused by various reasons such as storage media crash, sudden power-loss, partial download, virus attack on your storage media, header corruption, and due to any malicious software in your device.

  • While shooting slow-motion video or time lapse

If you're into the time-lapse videography or stop animation profession then most probably you've run into the common issue of inconsistent lighting or luminance. No matter if you're not changing the lens and camera setting but the flicker will persist which is actually due to less availability of light.

Moreover, while shooting slow motions there is always a need for more light with a special low-light camera having more FPS (Frame Per Second) facility in it. If you're not having these options then you may generate flickers while shooting.

  • Frame per second and Shutter Speed

When it comes to video, the frame rate and shutter speed go hand in hand, this is called the 180-degree shutter rule. This rule calls for doubling your frame rate for your shutter speed. For example: if your frame rate is set at 24 fps you should set your shutter at double speed to match 1/50. Now, technically it should be 1/48, but most of the cameras do not have this.

  • Due to Motion Blur

Motion blur is something that is not easy to capture. If you are shooting for motion blur and you're having a camera that can shoot at 6 fps or more, and with it, you need a faster shutter speed to take the perfect shot with motion blur. If not, then your video can produce an unwanted flicker.

Moreover, it also depends upon your artistic choice on how much motion blur you need in your footage. However, most of the movies use a standard motion blur rule with a 180-degree shutter rule, which says that your shutter speed should be double than frame rate to avoid flicker or disruption.

Part 2. How to Remove Video Flicker on Computer or Camera?

As discussed above, video flickering is one of the most annoying issues. It makes your videos look extremely unprofessional. It can be caused due to poor lighting setup, fluorescent lights, or LED panels. It can also be caused due to the source of the light and how many amps are going into the bulb.

In this section, we shall learn how to remove flicker from your videos on a computer or camera.

Solution 1. Camera settings that you should keep in mind.

Your camera setting mostly depends on the region you are in. In Europe, the recommended frame rate is 50 fps while in North America the standard frame rate is 60 fps. You should set up your shutter speed concerning the frame rate. The faster you go with the shutter speed, the more flickering you are going to get. For example - If you have set your shutter speed at 1/200 or above you are most likely to encounter flickering, it can be less or more depending on how much you increase or decrease the speed.

Solution 2. Use plugins in your video editing software

Plugins are quite easy to use and you can follow up the instructions provided with them to eliminate the flickering issue from your videos. They are available in paid as well as free versions. They are mostly compatible with your video editings software like Premiere Pro, Final Cut Pro, Avid, Resolve, and Vegas.

Solution 3. Buy a video repairing tool from a reliable source.

As mentioned above, it is most likely that the problem is because of the source of the video. Very often than not your original clip is intact but the problem is with your video data source, if that is the case then you should consider using repair tools. There are several video repairs tools available in the market that will resolve your issue of flickering.

Part 3. How to Fix Video Flickering on Phone?

With new and better phones being introduced in the market, people are using them instead of buying expensive cameras. Of course, phones are not high-quality video cameras, but they still provide very high-quality videos. Let us take a look at the steps by which you can eliminate flickering from your iPhone.

Solution 1: Turn off the portrait mode

iPhones are very well known for their cameras. Nowadays, they are generally coming with dual cameras. One is a wide-angle lens and the other one is a telephoto lens. Whereas wide-angle lenses offer generous aperture, telephoto lenses do not perform well in the dark.

It is advisable to turn off the portrait mode because this mode requires both the lenses to work simultaneously. Turning it off will reduce the flicker sensor factor when focusing on your subject.

Solution 2: Replace your LED lights

Lights are the main reasons for your videos to flicker, it does not matter whether you play them on the phone or your PC. Try changing your lighting and replace those low-quality LED lights from your set up. The camera captures the rapid changes in the brightness which we cannot see from our normal vision. That is why you should keep your lighting in check.

Solution 3: Hard reboot your iPhone

Try restarting your phone or force restarting your phone, if you will. This is not guaranteed, but this might fix your flickering issue. To force restart your phone, press and hold the sleep and home button and wait until the Apple logo appears on the screen.

Solution 4: Disable 60 FPS video recording on the iPhone

By default, iPhones are set to record videos at 30 FPS, but the newer generations offer a smoother recording of 60 FPS with 1080p resolution. High frame rate videos may give you some smooth videos but they will not be flicker-free. Disable the 60FPS video recording to get flicker-free videos.

Part 3. How to Avoid Video Flicker When Recording Videos?

Flickering is a common problem that is caused by certain frame rates and shutter speed combinations in artificial lighting. Avoiding flicker while shooting is much better than repairing your videos later. There are a few ways in which you can stop the flicker from happening.

  • Prefer Shooting in Natural lighting

Lights are the most crucial element when it comes to shooting a video. To avoid flickering in your videos, prefer shooting in natural lighting. This is the ultimate solution to all of your flickering issues.

  • Camera settings

While lights may solve most of your issues but you still need to keep your camera's setting in check, especially your frame rate and shutter speed. The value of these two elements should be as close as possible.

For example - If your shutter speed is set at 125 and the frame rate is nowhere near that value, you are very likely to discover flicker in your videos. Try keeping both values as close as possible but not the same. You can try setting the 120 fps frame rate and shutter speed to 125.

  • Flicker-Free tool

Technology has always saved us from many complicated technical things. You can use the Flicker-free tool calculator app just before starting the shoot which will make you find flicker-free shutter speed and frame rate combination when you're shooting under artificial lights.

  • Do you have a CMOS sensor on your camera?

The camera's having advanced CMOS sensors are now known to avoid flickering effects produced due to fluorescent LED lights, traffic signals, and other artificial lights. Sony has come up with a series of such cameras to avoid the effect of Video flickering while recording the footage. So, you can go for it, if you are always into more Cinematic and live recording fields to avoid frustrating flickers.

  • NTSC OR PIL

While shooting anything you should know that lighting frequency matters a lot as discussed above. If you're shooting in the America region then choose the NTSC settings in your camera and if you're doing the same in the Europe or Asia region then change it to PIL. This will help your recording device understand the region and its lighting intensity to capture the image accordingly.

Conclusion

So, these were the problems, symptoms, and solutions to flickering. We have tried to put our best in this article so that you can extract the most out of it.

We hope that our piece has helped you fully to understand the flickering concept and how to solve it.

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. It works in most video editing applications, such as Adobe After Effects, Premiere Pro, FCP X, Avid, Resolve and Vegas.

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.

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. 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.

Sometimes plug-ins can be complicated to understand and use. 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. If they don’t there are a number of parameters you can change to fine tune what the plug-in is doing.

Flicker Free Basic Parameter Overview

Sensitivity
This affects how much of the image Flicker Free is looking at. Usually set this between 10 and 30. If the flicker is affecting the whole frame, higher values are required. For smaller areas, set to a low value.

Time Radius
Determines the number of frames over time that Flicker Free is looking at. The higher the value, the better it’ll remove flicker, but the longer the render times.

Type
The three different algorithms available in Flicker Free. Time Lapse is appropriate for footage shot over long intervals. The Slow/Regular Motion algorithms are more appropriate for high frame rate video and footage shot at the normal 24/30 fps.

All Channels
This can produce much better de-flickering as each channel is processed independently. However, it can result in more artefacts.

Threshold
Only the Slow/Regular Motion – Alternate algorithm uses this parameter. Set between 5 and 20 for best results.

Detect Motion
Flicker Free will analyze the footage and try to account for fast moving elements in the scene. This usually will reduce any artefacts. However, with some footage, it can cause problems. So if adjusting the Time Radius and Type doesn’t solve your issues, try turning this off. Usually, it should be left on.

If you do need help, Digital Anarchy has a ton of tutorial videos on their site that guides you through each step on how to use Flicker Free.

I use Flicker Free in FCP X and it’s just a simple case of dragging the effect onto a clip. Flicker Free doesn’t require any ‘pre-analysis’ to work. 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. If I was happy with the result I would then just apply the same effect to the rest of the clip. 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.

Different types of flicker

As I mentioned earlier, flicker can occur from a wide array of shooting scenarios. 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. Flicker Free can get rid of this very easily.

Time Lapse Footage

Premiere Pro Flicker Removal Device

A time-lapse video requires taking a photo or a video frame at set intervals (eg. 1 sec., 10sec. 1min etc) and combining them to make a video. The biggest problem with doing this is that the exposure tends to change between frames. When played back this exposure change shows up as a kind of flicker in your final result.

Slow Motion Footage

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. These include certain fluorescent lights inside buildings, sporting venue, and even street lights. A lot of these lights cause flicker when shooting slow-motion footage at 120fps or higher. This flicker occurs because the AC can fluctuate in brightness as the electricity fluctuates (the ‘alternating’ in AC). The higher the frame rate you are shooting at, the more apparent it becomes. Flicker Free uses some clever software to smooth out the fluctuations to make the brightness consistent throughout the clip. It sounds a bit like a parlour trick, but it’s more of a clever algorithm than magic.

Archival Footage

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. Sometimes this old archival material will produce flicker. This can be because the film has degraded over time, it was shot under an old light that used to flicker, or the camera’s exposure was changing due to the fact it was being hand cranked.

Aerial Drone Flicker

This is probably something you have seen before if you have ever used a drone or watched drone footage. Drone flicker can be caused by a couple of things. The first is from the sun coming through moving propellors which ends up casting a shadow on the lens that results in flickering bands. The second is flickering caused by GOP compression artefacts. GOP stands for ‘Group of Pictures’ and is a common compression method. It groups multiple frames together to help get better compression rates. Typically this is 7 or 15 frames. In the case of the DJI Phantom drone, it uses a 7 frame GOP. This causes a shift in pixels every 8 frames. In some video footage, this is very noticeable as it’s rhythmic pattern and creates a shimmering type of effect. This is very noticeable in most of the DJI drones, especially those using low bitrate codecs.

Flicker Free can be used to lessen or eliminate prop flicker or the GOP compression problems. It uses a two-pass method to try and eliminate this flicker. From my experience, it doesn’t always work, but I have saved quite a lot of drone shots by using Flicker Free.

Processor hungry

The only caveat when using Flicker Free is that it requires a lot of processing power, although it doesn’t use the GPU on your video card. In FCP X it can take quite a long time to render the effect out. Digital Anarchy recommends that Background Rendering and Timeline Scrubbing are turned OFF.

I’ll give you an example as to why it is slow. If for example, you have Time Radius set to 10, Flicker Free is asking the host app to render 21 frames at once (the current frame, 10 before, 10 after) when processing a single frame. It then has to analyze all the colour information in those frames.

With 4K or larger resolution material, it can take a minute or two to render a single frame. If background rendering is on or scrubbing is active, FCPX will start trying to request all those frames for multiple frames at once. This can bring FCP X to a crawl or even crash it. Digital Anarchy recommends that you move to a point on the timeline, let it render, then make adjustments. Clicking around on the timeline without letting the current frame render will just slow things down even more.

Dropping the 4K sequence into a 1080p timeline doesn’t make a difference in render speed. It still has to access the 4K source file. However, rendering a 4K file out to a 1080p file and then re-importing it will make a difference. Now FCP X will just be dealing with HD frames and it makes a huge difference. If your final delivery is to 1080p or 720p, consider rendering out an intermediary file at that resolution. It’ll work much faster.

At the end of the day, it gets the job done, but if you are using an older computer or one that isn’t particularly powerful be prepared to go and make yourself a coffee because you will be waiting around, particularly if you are using Flicker Free on a long clip. For example, a 30 sec clip in a 1080p project should take about 4-6 minutes to render, but this will depend on the speed of the computer, how many cores you have/are using, the host application, and the settings within Flicker Free. If you have a 4K clip then it’s going to take a lot longer.

Where in the chain should you place Flicker Free

If you have other filters applied to your clip, it’s best to apply Flicker Free as the first effect in the effect chain. Often, the render can be dramatically increased when video effects are applied to a clip before Flicker Free does its flicker correction. The host app and type of filter will change the degree to which the render time will be increased. You can avoid this altogether by making sure Flicker Free is applied in your effect chain before any other filters that might change the way your footage appears.

Potential problems

Flicker Free isn’t going to work perfectly on every single occasion. It’s not a miracle worker and sometimes there will be cases where it’s not going to help you out. Occasionally you may see what appears to be shading on your footage after you apply Flicker Free. This is because Flicker Free is trying to blend multiple frames. This can be evident when there are high contrast areas and the camera is moving quickly. This may result in a phenomenon where the lighter areas are being affected by the darker areas. This causes something that looks like a shadow or shading. To try and fix this you can reduce the time radius, and/or try adjusting the threshold to a lower value.

Ghosting can also happen (although it is rare) when you apply the plug-in to fast moving objects. Again, it’s more of an issue with high contrast areas of the scene (e.g. a bright objects moving across a dark background). That object can appear in a frame with a type of ghosting effect of itself. Again, reducing the time radius and/or adjusting the threshold to a lower value can help.

Conclusion

As I mentioned in the article, Flicker Free isn’t a miracle worker and it can’t solve every problem you may encounter, but it does effectively and easily remove flicker in most scenarios. Being able to correct and save footage that suffers from flickering can be a lifesaver. Flicker Free is one of those plug-in-ins that once you start using it, you wonder how you ever lived without it.

Flicker Free retails for $149 USD, but you can download a free trial to see how well it works without needing to purchase.
