How to Spot Deepfake Videos: Step-by-Step Guide

This updated guide explains how to Spot Deepfake Videos through clear steps, practical examples, and important checks that help prevent common errors.

Method 1 of 3:

Examining the Image

Look for blurring on the person's face that's not in the rest of the video. When someone's face is superimposed over someone else's, their face rarely fits perfectly. That means the video's creator will need to blur certain areas to hide the fact that the video is fake. Look closely at the person's face to see if you notice any blurring. Then, compare the face to the person's body, the background, and objects in the video to see if the face appears blurry in comparison.^{[1]XResearch source}
- Their skin tone may also look different at the edges of their face.
Check for double edges around the eyes, mouth, and face. Look at the eyes, eyebrows, lips, and face outline to see if you can see 2 edges. This happens when a person's face is superimposed over a face that has a noticeably different face shape. When you see these irregularities, it's likely you're looking at a deepfake.^{[2]XResearch source}
- For instance, you might notice a weird outline around the person's eyes or mouth. Similarly, you might notice that their eyebrows are 2 different colors.
Tip: You may also notice that hair and teeth are missing. When they smile, check to see if the teeth look real or not.^{[3]XResearch source}
Consider if the person in the video rarely blinks. People typically blink every 2-10 seconds, and each blink takes 1/10 to 4/10 of a second. However, deepfake programs aren't able to accurately depict blinking, so you'll notice less blinking. Watch the person's eyes to see if they blink normally.^{[4]XResearch source}
- Count between blinks to help you determine if it's normal.
Notice if the person's eyes look weird when they blink or close. Deepfake programs use existing photos of a person to create a simulation of them. However, most people aren't photographed with their eyes closed, so it's hard for the program to simulate closed eyes. Pay careful attention to the person's eyes to see if they look odd while they're closed.^{[5]XResearch source}
- The eyes may look blurry, discolored, or computerized if the video is a deepfake.
Look for shadows and reflections that don't match up. Some deepfake videos are made by combining 2 videos. Fortunately, you may be able to spot these fakes by checking the placement of shadows and reflections. Typically, every shadow should go in the same direction, including shadows from people, buildings, and large items. Similarly, reflective surfaces like mirrors, Windows, and water surfaces will show consistent reflections.^{[6]XResearch source}
- This works great for videos that don't focus on a speaker's face. For instance, if you're looking at a crowd on the street, check to see that the shadows from the buildings and members of the crowd go in the same direction.
- Similarly, let's say you're looking at a video of a protest that allegedly got out of control. If you noticed that the storefront Windows in the video showed the reflections of just 2 people while the video had a crowd of people, it may be a deepfake.
Make sure everything in the video looks like it's to scale. Since these videos are altered, the people, objects, and background may not match up. Look for inconsistencies, like buildings that are too big, body parts that look misshapen, and objects that look larger than usual. These can be a sign the video is a fake.^{[7]XResearch source}
- As an example, you might notice that the people in a protest seem really tall compared to the buildings around them.
- Similarly, you may notice that a person's head looks way too big for their body.

Method 2 of 3:

Checking the Audio

Read the person's lips to see if it matches the audio. Focus on the person's lips as they speak and watch to see if their lips are forming the words they're saying. Additionally, notice if the lips appear to simply move up and down without actually forming words. This might be a sign that the video is a fake.^{[8]XResearch source}
- For example, say the Word 'oh' and notice how your lips make an 'o' shape. Then, say the Word 'hi' and notice that your mouth opens more and doesn't make an 'o.' The person who's speaking in the video should be making the same shapes with their mouth.
Notice if the person's reactions don't match up with what they're saying. Typically, when a person speaks, their facial expression, tone, and gestures all match up with what they're saying. Since deepfakes aren't real, the person's reactions and expressions may not match up with what they're saying. Pay careful attention to how they seem to feel about what they're saying to see how it compares to what's being said.^{[9]XResearch source}
- Let's say you're watching a video of a presidential candidate who's saying that they hate their country. If you notice that the person seems to be shaking hands and laughing as they talk, you might suspect that it's a fake video.
- Similarly, let's say that the person in the video is a politician who's declaring that they aren't going to do their job anymore and instead they're just going to throw pies at congress. If their tone and facial expressions appear very serious, it's likely the video is a fake.
Listen for sound issues, like volume issues, voice changes, or glitches. Pay attention to the audio so you'll notice if some words and phrases are louder than others or if the voice seems dubbed. Additionally, consider if the speech sounds robotic or like the syllables were forced together. These might be signs of a fake video.^{[10]XResearch source}
- For instance, you might notice that the speech sounds autotuned and mechanical.
Notice if the person's voice doesn't sound right. A lip synced deepfake video takes an existing video and adds different audio. If the new speech is very similar to the old speech, it might be hard to spot visual differences. However, consider if the person's voice sounds different than usual. This can be a sign of a fake.^{[11]XResearch source}
- For example, let's say you're watching a video of an actor admitting to assaulting someone. If their voice sounds different, it could be a fake.
Consider if the speaker is using a monotone voice. When the speaker's voice can't be accurately duplicated, it's common for a video's creator to add a monotone voice instead. Notice if the speech seems to lack all emotion and inflection. If it does, you may be watching a fake.^{[12]XResearch source}
- For example, let's say you're watching a video of a politician calling for war. If the person seems disinterested and their tone of voice is flat, it's likely the video is a deepfake.

Method 3 of 3:

Evaluating the Credibility

Trace the video back to its source. Look to see if a credible website or account is sharing the video. Similarly, check the URL of the video to see if it's from a legitimate website. If it's not, then the video is likely a fake.^{[13]XResearch source}
- For example, let's say the video originated from a page called 'Bob Hates Politics.' This may make you question it's legitimacy.
- However, if the Washington Post shared the video, it might be real.
Search the contents of the video to look for corroborating sources. Open your favorite Internet browser and type in the topics you see brought up in the video. Then, go through your results to look for credible sources that back up or discredit the contents of the video. Read the articles you find to figure out if the video may be a fake.^{[14]XResearch source}
- For example, let's say you see a video of a senator saying she needs to ban all religions. You could type 'senator needs to ban all religions' into your search bar. Then, read what comes up, but also check the credibility of your sources.
Consider where the video is being shared. Most deepfakes are shared directly to social media, like Facebook and Twitter. From there, it's common for them to go viral. When you see these videos, look at the original profile that shared it. Additionally, check if you can find it being shared on other sites.^{[15]XResearch source}
- For example, let's say you're on Facebook and you see a video of a politician you hate saying something really stupid. Before you assume it's real, check several credible news sites to see if they're sharing the video, too. If it's real, chances are every news outlet is going to be sharing it.
Question videos that seem too crazy to be true. Deepfake videos usually include inflammatory, embarrassing, or satirical material. That means they'll likely trigger a strong reaction in you. When you see material that seems particularly upsetting or over-the-top, consider that it might not be true. Then, do your own research to find out if you can believe what you saw in the video.^{[16]XResearch source}
- It's especially hard to do this if you see something that confirms someone you dislike is a terrible person. However, it's important that you verify what you're seeing before you believe it.
- Try not to share videos that you aren't sure are real because it spreads false information.
