This paper presents Inter prediction Multiple Reference Frames Impact on H266-versitele video coding (VVC) encoder. Video compression plays a crucial role in storing and transmitting video content. Recent developments in video coding have led to the development of the H266-VVC encoder, which aims to achieve greater compression efficiency than its predecessors. One of the key features of the H266-VVC encoder is its inter prediction method, which uses previously encoded frames as reference frames. Multiple reference frames are used in this study to determine how they affect the performance of the H266-VVC encoder. The use of the multiple reference frames, increases compression efficiency by providing more information for inter-prediction. The encoder must compare more frames to find the best match when using multiple reference frames, so it also increases the encoding time. To achieve the best compression efficiency and encoding speed, a trade-off between reference frame number and encoding time must be taken into account when selecting the number of reference frames to use in the H266-VVC encoder.
