H.265/HEVC is a great successor to H.264/MPEG-4 AVC. Many guys have access and apply this codec for better video quality and smaller size. However, many users just realized that they can't play HEVC videos on Mac via Photos, VLC, and QuickTime. For example, Handbrake encoded HEVC MP4 videos can't be played on macOS High Sierra or later in QuickTime, HEVC is choppy or plays sound but not picture, VLC freezes when playing HEVC files or pops up a "No suitable decoder module" error, or they simply get an error message "Photos cannot play this video because it uses an unsupported format" etc.

Why HEVC video won't play on MacBook Pro/Air, iMac etc? The fundamental reason comes that HEVC is not supported widely. The fact is that HEVC/H.265 file is absolutely not supported on Photos app and QuickTime Player, and you cannot play 4K H.265 on VLC without an installation of x265 codec. From an operating system perspective, HEVC codec is only compatible on macOS Higher Sierra or later. And old hardware can also result in HEVC video playback failure with lags and stuttering, as well as getting Mac computer overheated with exhausted CPU usage.
Upgrading macOS and enhacing the hardware only ensure that your Mac computer owns the ability to play HEVC video. As to whether it can be played successfully or not, it relies on the HEVC player to the end. But unfortunately, QuickTime and Photos don't support the HEVC codec natively, and VLC can only access codec in "hvc1" instead of "hev1" after x265 codec installed. Thus, rather than spending a lot of money and time on upgrading computer software and hardware for HEVC playback, why not use a HEVC/H.265 converter to make HEVC video compatible with your current Mac? MacX Video Converter Pro is the best option!
Step 3. If you don't want to change the HEVC codec of 4K UHD video, you can choose MP4 Video (HEVC) as an output and click on the gear-shaped Settings button to adjust the video parameters. For example, lower the bitrate by 20%-50%, maintain the frame rate for great fluency, and lower 4K resolution to 19201080 or retain the original if your MBP is available for 4K UHD playback.
After installing HEVC codec on your Mac, you can play HEVC files on Mac. DivX is a great choice which supports HEVC up to 4K. It is compatible with both Windows and Mac. It has a free version and a pro version. Both versions can play HEVC up to 4K, but only the pro edition is designed with HEVC 10-bit playback ability.
This weekend I experimented a little with re-encoding videoas H.265/HEVC, now that the codec has good support on bothhardware and in Mac OS/iOS. The FFmpeg wikiestimates that you should be able to produce video files ofsimilar video quality as H.264 that are about half thesize. That sort of space saving should be interesting toeverybody, but especially for those who carry videos aroundon laptops, which still tend to come with SSDs of modestsize even in the advanced year of 2019.
Spec: You SHOULD use video formats in which the parameter sets are stored in the sample descriptions, rather than the samples. (i.e., Use 'avc1', 'hvc1', or 'dvh1' rather than 'avc3', 'hev1', or 'dvhe'.)
Although computers, mobile phones, tablets, etc. have made it simple to watch movies and music videos, they have limitations on the support of video codecs. Many devices can't recognize HEVC-encoded footage. Thus, there is often the need to be involved in converting HEVC files for compatibility. In this article, we're going to introduce how to convert HEVC to MP4 with HEVC converters.
For an experienced user, you can fine-tune the output parameters through "Advanced Settings". Just click the gearwheel button next to the output profile format to open the window. Then, customize video resolution, bitrate, frame rate, as well as audio codec, channel, sample rate, etc. to further optimize conversions.
Choose the output directory and click the button on the lower right side of the interface to let the HEVC codec to MP4 conversion begins. Once done, click the button to locate your converted MP4 files.
In addition, it provides totally 15 output formats or containers by default, such as VP80 + Vorbis (Webm), H.264 + MP3 (TS), WMV + WMA (ASF), CD, and more. To choose other formats, you have to manually select the combination of audio and video codecs.
This guide introduces the video codecs you're most likely to encounter or consider using on the web, summaries of their capabilities and any compatibility and utility concerns, and advice to help you choose the right codec for your project's video.
Most video codecs are lossy, in that the decoded video does not precisely match the source. Some details may be lost; the amount of loss depends on the codec and how it's configured, but as a general rule, the more compression you achieve, the more loss of detail and fidelity will occur. Some lossless codecs do exist, but they are typically used for archival and storage for local playback rather than for use on a network.
The following video codecs are those which are most commonly used on the web. For each codec, the containers (file types) that can support them are also listed. Each codec provides a link to a section below which offers additional details about the codec, including specific capabilities and compatibility issues you may need to be aware of.
As is the case with any encoder, there are two basic groups of factors affecting the size and quality of the encoded video: specifics about the source video's format and contents, and the characteristics and configuration of the codec used while encoding the video.
The simplest guideline is this: anything that makes the encoded video look more like the original, uncompressed, video will generally make the resulting data larger as well. Thus, it's always a tradeoff of size versus quality. In some situations, a greater sacrifice of quality in order to bring down the data size is worth that lost quality; other times, the loss of quality is unacceptable and it's necessary to accept a codec configuration that results in a correspondingly larger file.
The degree to which the format of the source video will affect the output varies depending on the codec and how it works. If the codec converts the media into an internal pixel format, or otherwise represents the image using a means other than simple pixels, the format of the original image doesn't make any difference. However, things such as frame rate and, obviously, resolution will always have an impact on the output size of the media.
Additionally, all codecs have their strengths and weaknesses. Some have trouble with specific kinds of shapes and patterns, or aren't good at replicating sharp edges, or tend to lose detail in dark areas, or any number of possibilities. It all depends on the underlying algorithms and mathematics.
The degree to which these affect the resulting encoded video will vary depending on the precise details of the situation, including which encoder you use and how it's configured. In addition to general codec options, the encoder could be configured to reduce the frame rate, to clean up noise, and/or to reduce the overall resolution of the video during encoding.
The options available when encoding video, and the values to be assigned to those options, will vary not only from one codec to another but depending on the encoding software you use. The documentation included with your encoding software will help you to understand the specific impact of these options on the encoded video.
The AOMedia Video 1 (AV1) codec is an open format designed by the Alliance for Open Media specifically for internet video. It achieves higher data compression rates than VP9 and H.265/HEVC, and as much as 50% higher rates than AVC. AV1 is fully royalty-free and is designed for use by both the element and by WebRTC.
The MPEG-4 specification suite's Advanced Video Coding (AVC) standard is specified by the identical ITU H.264 specification and the MPEG-4 Part 10 specification. It's a motion compensation based codec that is widely used today for all sorts of media, including broadcast television, RTP videoconferencing, and as the video codec for Blu-Ray discs.
Non-web browser implementations of WebRTC (any implementation which doesn't include the JavaScript APIs) are required to support AVC as a codec in WebRTC calls. While web browsers are not required to do so, some do.
ITU's H.263 codec was designed primarily for use in low-bandwidth situations. In particular, its focus is for video conferencing on PSTN (Public Switched Telephone Networks), RTSP, and SIP (IP-based videoconferencing) systems. Despite being optimized for low-bandwidth networks, it is fairly CPU intensive and may not perform adequately on lower-end computers. The data format is similar to that of MPEG-4 Part 2.
H.263 has never been widely used on the web. Variations on H.263 have been used as the basis for other proprietary formats, such as Flash video or the Sorenson codec. However, no major browser has ever included H.263 support by default. Certain media plugins have enabled support for H.263 media.
Unlike most codecs, H.263 defines fundamentals of an encoded video in terms of the maximum bit rate per frame (picture), or BPPmaxKb. During encoding, a value is selected for BPPmaxKb, and then the video cannot exceed this value for each frame. The final bit rate will depend on this, the frame rate, the compression, and the chosen resolution and block format.
The High Efficiency Video Coding (HEVC) codec is defined by ITU's H.265 as well as by MPEG-H Part 2 (the still in-development follow-up to MPEG-4). HEVC was designed to support efficient encoding and decoding of video in sizes including very high resolutions (including 8K video), with a structure specifically designed to let software take advantage of modern processors. Theoretically, HEVC can achieve compressed file sizes half that of AVC but with comparable image quality. 2ff7e9595c
