Since H.265 is 25-50% more efficient you should be able to reduce the Bitrate and still maintain the same video quality.When you watch a movie with subtitles, they are sometimes too fast or slow. Note: If the source video was in H.264 format you can also use the H.265 command to produce a final video in H.265/HEVC format.

H.265/HEVC files are 25-50% more efficient but decoding is much more compute intensive. You likely have hardware support for encoding and decoding. Tradeoff: H.264 has the most compatibility. Tradeoff: While hardware accelerated encoding using GPUs is generally significantly faster, software encoding (CPU only) produces smaller files and better quality. Note that this will take some time depending on the video duration, quality and the quality of your CPU and GPU. We will need to render the video again with the subtitles permanently added into the video stream.
