Analyzing UFO videos through interpolated closeups

This document can help you analyze UFO videos through the following process:

1. Find a UFO video that is useful for analysis. 
2. Identify interesting UFO behaviors and make screenshots of selected frames.
3. Extract interpolated UFO closeups (enlargements) from selected frames. 
4. Create a slideshow of sequential UFO closeups.

Note: This document includes specific procedures for analyzing YouTube UFO videos. For analyzing Facebook videos, you need slightly-different procedures. For more information, please see my document, How to analyze UFO videos.

Finding a UFO video useful for analysis

A UFO video can be useful for analysis if it meets the following requirements:

• Published by a website not listed in the UFO Theater, which blacklists sites that promote phony UFO videos. 
• Not an obvious hoax. Note: Always be careful, you can find video hoaxes on any UFO website.
• Exhibits an authentic unknown object that is probably neither a natural phenomena nor a human aircraft.
• Includes images that might be large enough. After you zoom a video frame, and crop its UFO image, you should see some its basic features. For example, a bright light can never exhibit features regardless how much you magnify it.

Identifying interesting UFO behaviors

After you find a useful UFO video, you can identify portions of that video in which the object is performing interesting behaviors, such as making changes to its:

• Direction 
• Speed 
• Brightness 
• Color 
• Size 
• Shape

To identify interesting UFO behaviors, do the following:

1. Start playing a YouTube UFO video, pause it, and then copy its URL. Note: Play the video directly from the YouTube website. If you have accessed the video through a third-party website, click on the YouTube icon (tooltip: Watch on www.youtube.com) to watch the video directly through YouTube.
2. Open a new browser tab, and do either of the following:
• Go to RowVid, paste the URL into the ENTER VIDEO URL OR ID field, and click WATCH VIDEO.
• Go to Anilyzer, paste the URL in the ENTER VIDEO URL field, select YouTube, and then click WATCH VIDEO.
3. Click Settings (the gear icon), click Quality, and then select the highest possible quality; preferably 1080p.
4. Watch the entire video, writing down times at which the most-interesting UFO behaviors occur. You can restart the video as often as necessary. 
5. Within the video portion that contains each interesting action, do the following: 
1. Click 0.25 for the slowest video speed. 
2. Click either the forward or back arrow button to stop the video at a specific frame, and then continue clicking these buttons until you find a frame you wish to save as screenshot. 
3. Click the icon at the lower right corner of YouTube, select Full screen, press Print Screen to display a Save Screenshot dialog, and then click Save to copy the screenshot of the frame to a working folder. Note: To keep track of your UFO screenshots, you should associate each filename with its video time. For example, I made a screenshot of a frame that had been recorded at 58.06 seconds, and then stored it as filename 5806.png in my working folder (You cannot use a decimal point in any number within a filename.)

Extracting interpolated UFO closeups
After you identify interesting portions of a UFO video, you can extract interpolated closeups of the unknown object performing an interesting action. To extract an interpolated UFO closeup, do the following:

1. Create a screenshot of an interesting UFO action according to the above procedure for Identifying interesting UFO actions.
2. Use image-editing software, such as GIMP, to zoom into the screenshot as closely as possible, typically 800%.
3. Crop the UFO screenshot to approximately 50 by 50 pixels.

   

   Figure 1 - UFO screenshot cropped to 50 by 50 pixels.
   This is a closeup that has not yet been interpolated.

4. Scale the image; resize it to 400 by 400 pixels, and use the best possible interpolation, such as Sinc (Lanczos3). This exhibits only the center portion of the image.
5. To see the entire image, zoom out to 100%.

6. Save (export) the interpolated UFO closeup into a separate working folder. Note: For each each interpolated closeup, you can use a filename associated with its screenshot and video time. For example, I stored the interpolated UFO closeup in Figure 2 as filename 5806.jpg in a working folder.

As shown Figure 1, an uninterpolated UFO closeup has relatively few pixels, typically 2500 (50 X 50). Therefore, you cannot see details as clearly as you might prefer because each pixel appears as a relatively-large square. However, when you use graphics software, such as GIMP, to scale (resize) the closeup to a larger size, that software also uses interpolation to calculate many new pixels that smooth out the differences among the original pixels. As shown in Figure 2, an interpolated UFO closeup has many more pixels, typically 160,000 (400 X 400). Interpolation enhances the closeup and helps us see general shapes and features. While not perfect, an interpolated closeup shows more than it did prior to interpolation.

Creating a slideshow of interpolated UFO closeups

Creating a slideshow of sequential, integrated closeups can help you analyze UFO actions over time. You can use any slideshow or presentation software. For example, by uploading sequential interpolated closeups to Google Slides, I've created all my UFO-analysis slideshows associated with this blog.
