Abstract: : Video steganography is a robust method for concealing confidential information within video files, ensuring data privacy, and safeguarding against unauthorized access. This study presents a secure video steganography technique incorporating the ChaCha20 encryption algorithm to bolster data security before embedding. ChaCha20, recognized for its agility and resilience to cryptographic threats, encrypts the hidden data before it is inserted into chosen video frames using the Least Significant Bit (LSB) method. This ensures minimal misrepresentation and preserves the perceptual quality of the video while providing a strong layer of security. In this proposed system, once input files are selected, the ChaCha20 algorithm automatically generates a key file. This key file is then used to retrieve the concealed information, ensuring a smooth and secure decryption process. The concealed data is extracted and decrypted accurately at the receiver's end. Experimental results demonstrate that the proposed method achieves high noiselessness, low computational overhead, and vigorous security, making it a reliable solution for secure video-based communication
