Ffmpeg Convert To Hevc

Currently I have demuxed a test episode to UHD hevc layer, primary surround soundtrack layer and PGS stream 0 layer. I am running the following ffmpeg command (grabbed from a forum online) to convert the UHD HEVC layer to 1080p(rec709).

Speed. With ffmpeg and a decent GPU (like a Quadro P4000) the h265 HEVC encoder finaly gets a good speedboost with up to 90fps when encoding HD movies with the below parameter values and 200fps when using the GPU accelerated h264 encoder.. This speed is achieved with a Quadro P4000 from NVidia when encoding 1920#215;1080 movies with -preset slow.The GTX 780 ...

This guide focuses on the encoder libx265 which can offer around 25–50% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. These gains will be most pronounced at resolutions of 1080p and higher. See HWAccelIntro for information on supported hardware H.265 HEVC encoders.

The -i parameter specifies the input video file, in this case “video.mp4”. ffmpeg can decode a whole variety of video formats including .avi, .mp4 and .mov.. The -c:a copy parameter tells ffmpeg to copy the audio stream from the original file directly into the output file. While -c:v libx265 tells ffmpeg to encode the new video file in H.265 format.

Answer (1 of 7): The only way to do the conversion without losing quality is to compress to lossless mode H.265. Uncompressing then recompressing with lossy DCT-based codecs always causes additional loss. Every H.265 codec I’ve tested on major platforms has supported lossless mode H.265, so you’
