## 4 Comparative Results
Fast-motion segments generally exhibit lower PSNR values due to having lower redundant data in the video, which makes data-hiding more challenging. \begin{table}

In summary, across all video segments and motion types, there is a clear inverse relationship between embedding capacity (bpp) and video quality (PSNR). Lower embedding rates consistently yield higher PSNR values, underscoring the importance of optimizing the balance between the data-hiding capacity and resultant video quality. This trend holds true across various types of motion and video segments, validating the effectiveness of the proposed Octree-hiding technique. For the Documentary slow-motion segment (Table 7), a significant improvement in PSNR is noted with decreasing bpp. The PSNR reaches 46.98 dB at the lowest capacity of 17.65 bpp and \(C=0.75\). This suggests that the proposed technique is highly effective in maintaining video quality at lower embedding rates for slow-motion content due to the high redundant information data available, which can be exploited for efficient data-hiding. \begin{table}
