For example, you can adjust the Frame Rate from 23.97 to 25/29.97/30, upscale the resolution from 720p/1080p to 2K/4K like 2560x1440, 4960x2160, 3840x2160, etc, you can add srt subtitle file, cut and trim the video, or merge video clips. If necessary, you can tune video audio parameters and make editing. Scroll down on the Output Profile window, click PC General Video under Common Video Profile and select HEVC Video (Codec: HEVC + aac), which will transcode MKV H.264 to MKV HEVC video. Step 1: Download, install and open the free MKV to HEVC video converter on your PC or Mac.Ĭlick "+Video", browse on your computer to find the source MKV (H.264) video file, and click Open to add it to the MKV to HEVC converter. At the meantime, the output file size of the HEVC video is greatly reduced at no visual quality loss. The Nvidia, Intel, and AMD GPU acceleration is supported to convert videos from MKV to HEVC at a fast speed. Part 1: How to Convert H.264/AVC MKV to HEVC/H.265 for Smaller Size & High QualityĪs MKV usually has a large file size due to the support for the extra features, multiple audio tracks, and subtitle tracks, converting MKV to HEVC is a good way to save the space.įree Video Converter, a free MKV to HEVC video converter, can convert HD/4K AVC MKV to MP4 HEVC, or change the underlying MKV codec to HEVC at the lowest possible bit rate without loss in visual quality. Part 2: When the source MKV is encoded with HEVC.Part 1: When the source MKV is encoded with H.264, VP9/8. MKV will accept almost anything you throw at it, while mp4 has a lot of restrictions on what you can put in it. What will differ however is what the container supports. That means, when HEVC (x265) is encoded in MKV and MP4 containers, at the same bitrate with the same codec, the video will be the same. tsa used by ATSC, DVB and Blu-ray disc of MPEG transport stream also can be. The file extensions of HEVC/H.265 can be. It's a video codec which is included in various video containers. HEVC (High Efficiency Video Coding) is a compression scheme or standard to improve video quality at the same bit rate or reduce the file size (about 50%) at the same level of video quality. It's able to contain video streams in different codecs, including H.265/HEVC, H.264/MPEG-4 AVC, MPEG-1, MPEG-2, MPEG-4 (A)SP, VC-1/WMV, Real Video, Theora, Microsoft MPEG4 V2, VP8, VP9, MVC. MKV (Matroska) is an open source free container format that can have Selectable subtitle/audio/video streams, Chapter entries, Full metadata (tags), Menus (like DVDs have), etc. Anyway, no matter what codec is contained in the source video file, you can free convert the MKV to HEVC fast with high quality as per the guide below. Therefore, sometimes we need to convert MKV from other video codecs like H.264 to HEVC to make the MKV video smaller while some other times we simply want to change the container from MKV (h.265) to MP4 (HEVC) to make the video more compatible for different platforms. MKV is a video container and HEVC is a video compression format. How to Free Convert MKV to HEVC Fast with High Quality
