Hi every one. 265/HEVC is not widely supported, we often need to convert this file type to H. Premiere has a pretty easy workflow for that. Lossy transcoding like this is never ideal, but for some types of content you can absolutely get This guide focuses on the encoder libx265 which can offer around 25–50% bitrate savings compared to H. mp4 -vf scale=1920:1080 -c:a copy output1080vid. 264 video encoded with libx264, while retaining the same visual Yes, using ffmpeg.
