Question

(Q3) Encode each of these videos at the following target bitrates using MPEG-2 and H264: Bitrate Input bitrate BR1 5000 - BRO BR2 4000 - BRO BR3 3000 - BRO BR4

2000 - BRO BR5 1000 - BRO BRO (Bitrate Offset) = ceil (Last 3 digit (Z#)/2) For instance, if Z123456789, BRO-ceil (789/2); if Z234564013, BRO = ceil (013/2). For each video, complete the following table with actual bitrate achieved, corresponding Y PSNR and encoding time collected from the output of the ffmpeg encoding process. Record data in one table for each of the five videos. Video Name: Sunflower BR1 BR2 BR3 BR4 BR5 Bitrate achieved (MPEG 2) PSNR (MPEG 2) Encoding Time (MPEG 2) Bitrate achieved (H264) PSNR (H264) Encoding Time (H264)
