Deepfake Analysis - Resolution: src 360p 7sec + dst 360p 7sec [default]

INTRODUCTION

We are going to determine the requirements of image material to create a successful deepfake. Two videos will be shown for each of these test cases. The first case shows the results of merging the faces using the standard parameters (default). In the second case, each of the parameters for merging the faces is manually tweaked until they produce the best possible results. The YouTube video Bush's Best Speech was used as the output video for all tests.

TEST CASE

The question here is how will the standard resolutions of the video affect the fake. To test the effect of the standard resolution on the deepfake, different renderings were performed with videos in 360p and 720p resolution.

OBSERVATION

First, the results from the source and output video in 360p resolution were compared with the source and output video in 720p. The newly created 360p fake was compared with the video from the case source video "500 images ⇒ output video 7 seconds (168 images)" in 720p resolution, which was covered in the recent article. Apart from the poorer quality of the new 360p video, which was basically to be expected, and the somewhat blurrier edges, it still achieved decent results. Less obvious was the somewhat darker face compared to the video in 720p resolution, although nothing about the images, except for the resolution, was modified for either fake.
