3 Easy Ways to Convert HEVC to MP4 - HEVC Converters

Summary: Are you looking into how to convert HEVC to MP4? This guide will shed light on why it is necessary to convert HEVC and how to convert HEVC to MP4 by using some paid or free HEVC-to-MP4 converter software like HandBrake and VideoProc Converter AI.

High Efficiency Video Codec (HEVC), also referred to as H.265 and MPEG-H Part 2, has never been more popular than it is today. HEVC remains the king of high-efficiency codec, especially for using in High Dynamic Range (HDR), 10-bit and Dolby Vision content. The prosperity of this high compressed codec owns much to the support from the leading hardware, software, and digital ecosystem companies. The number of the installed base that can decode HEVC in 2020 is around 3.644 billion from estimated. This includes recent iPhone devices that can capture and receive HEVC videos, the majority of the action cameras, and drones, etc.

However, the license fee for using the HEVC codec in hardware, software, and contents are far more expensive than its older brother H.264, let alone open source ones like VP8 or VP9. Besides, the popularization of a new industry standard codec often takes years. It's still uncertain whether HEVC can be the next standardized video codec. Thus, before that, many companies still have concerns about making this high-priced investment. Browsers like Google don't natively go compatible with HEVC, most of the video editing software and media player still get some trouble to process HEVC files, such as:

• Can't view GoPro footage
• iPhone HEVC video won't play on vlc
• HEVC videos from Canon EOS R10/R7 won't play
• HEVC codec missing in Premiere Pro
• Sony TV won't play H265 HEVC videos
• HEVC is unsupported by Windows 11 and 10 out of the box
• and so on

And the easiest solution to all HEVC related errors is: Take a solid HEVC converter to change HEVC to MP4 H.264. In fact, whether you intend to convert HEVC to another more compatible format or transcode a video to HEVC for shrinking size, you'll need a capable HEVC converter.

How to Free Convert HEVC to MP4 with HandBrake

HandBrake is a free and open-source video converter program runs on Windows, Mac, and Linux. It comes with the capability to convert HEVC files to MP4, H.264, MPEG-2, MPEG-4, Thera, VP8 and VP9, and vice versa.

It is a feature-rich HEVC converter. However, the plethora of difficult jargon, out-of-date interface, and limited output container options (MKV, MP4, AVI) are just a few of the things that have led me and many other beginners to oft-favor a certain other HEVC converter. Too many redundant steps are required by Handbrake to batch convert HEVC videos, and the extremely unstable performance are also biggies.

Let's see the detailed steps to convert HEVC to MP4 for free with HandBrake!

Step 1. Launch up HandBrake on your PC or MAC. Drag the source HEVC video that you'd like to convert and drop it to this free HEVC to MP4 converter. The process is the same if you need to convert a video that comes with another format. You can also click on File and then select the original file to load it up to Handbrake.

Step 2. On the main interface, change the video container from MP4, MKV, and AVI if necessary. After that, click on "Video" to enter a new section. Unfold the drop-down box of "Video Codec", you'll be given H.264, HEVC 8-bit/10bit, MPEG, and some other codec options. Click on the target codec.

Step 3. You can leave the "Framerate" value as the default or set a specified value. Move the cursor on the quality slider left or right to decrease or increase the quality.

Step 4. HandBrake won't automatically change the audio codec to match the selected audio codec. Therefore, you sometimes need to adjust the audio codec manually to get avoid any no audio or a/v out of sync problems.

Step 5. Click on "Summary" to check the resolution, bitrate, sample rate, and other properties of your media tracks.

How to Free Convert HEVC to MP4 with FFMPEG

FFMPEG enables you to convert HEVC to MP4 H.264 and other prevalent codecs. You can also utilize it to turn H.264, VP8, or other videos to HEVC high-compressed format.

Unlike common software that comes with interface with well-designed guidance, FFmpeg offers you only a command window. This means you have to input the proper command line to apply any converting decisions. It usually takes a steep learning curve for those who don't know a command line environment to do even the most simple thing by using FFmpeg. Keep reading on the step-by-step guide on converting HEVC with FFmpeg on Windows, you'll know what I mean.

Let's see the detailed steps to convert HEVC to MP4 for free with FFmpeg!

Step 1. Go to the FFmpeg official download site. There you are given many versions correspond to Windows, Mac, and Linux respectively. After you choose which operating system you want to install in, you'll be led to the FFmpeg Builds Page which displays the version, architecture, linking, and license information of the installation package that you are going to acquire.

Step 2. Click on Download Build. In my case, I download Windows 64-bit static version.

Step 3. Once the installation package is successfully downloaded on your computer, you need to take 7zip to extract the ffpmeg.exe.

Step 4. Move over to your system directly (in most of the cases, the OS/C: folder), and create a new folder named FFmpeg.

Step 5. Paste the expanded files for the ffmpeg.exe to this newly created folder.

Step 6. Navigate to your computer, click on "System properties", select "Advanced system settings", choose "Environment Variables", and tab New. There you set the variable name as Path, and set the "Variable value" as C:\FFmpeg\bin.

Step 7. Press Windows and R button on your keyboard, and input CMD to launch up the Command Prompt window in administrator mode.

Step 8. Copy the path of the source HEVC video.

Step 9. Press the blank button on your keyboard, input cd, and then press the space button again. There you paste the copied source video path and press Enter.

Step 10. Enter ffmpeg -i test.m4v -c:v libx264 -crf 18 -c:a copy output.mp4, and then press "Enter".

test.m4v is the name of my file plus the extension. Suppose your source media is test.mkv, there you need to enter ffmpeg -i test.mkv -c:v libx264 -crf 18 -c:a copy output.mp4. Assume you need to convert H.264 to HEVC MP4, you need to input: ffmpeg –i my_movie input.mp4 -c:v libx265 -vtag hvc1 output.mp4.

The given commands are just our recommendation that can deliver high-quality output. There are also lots of other available command lines, you can come over to FFmpeg Encoding Guide to get more information.

Step 11. FFmpeg now starts to transcode and encode the source HEVC file to MP4. This process may eat up your CPU and memory storage. I just take a screen capture during the processing process, and it shows that CPU usage rage blasts up to 94.9%, and the memory usage rate rises to 54%.

HEVC to MP4 Conversion: Optional Reading

1. Is HEVC Better Than MP4 H.264/AVC

HEVC is superior to H.264 with regard to storage, bandwidth saving, and picture quality. HEVC video looks more crispy and retains more details than H.264 when the given bitrate and other properties are the same. This owned a lot to the application of the more advanced compression algorithm which is featured with coding tree unites based blocks, the optimized motion-vector prediction, 35 directional intra prediction modes, and enhanced interpolation filter, etc.

1) HEVC VS MP4 H.264: Some Key Improvements

A. Block Size

The basic building units of H.264/AVC are the macroblocks^[3], which consist of 16 × 16 samples. However, many recent studies found the larger pixel block size is much more efficient to compress high-resolution videos. The small 16x16 blocks are insufficient to capture the increased spatial correlation from 1080P and other large videos. In HEVC, a slice is subdivided into multiple CTU(coding tree units)^[4]. Depending on the complicity of the picture, these CTUs can have different size: 16 x 16, 32 x 32, 64 x 64. In this way, the efficiency and flexibility of compression can get improved.

B. lock Partitioning Structure

Unlike the macroblock of H.264, the CTUs of HEVC includes CU (Coding Unit), PU (prediction Unit), and TU (Transform Unit). The separate of these 3 units make the division of each portion better fits the texture features of motion pictures, brings up much flexibility in transformation, prediction and coding process, and is good for fulfilling the function of each unit.

C. Parallel Tool

The coding of HEVC is much more complicated than H.264. To facilitate the coding efficiency, two high-level parallelization tools^[5] are introduced to HEVC: Title and WPP (Wavefront Parallel Processing). Tiles divide a picture into several rectangle groups of coding tree blocks. Each Tile can be regarded as an LCU (Large Coding Unit) that allows being decoded separately. By using WPP, the consecutive rows of CTUs is decoded in parallel using multi threads. With the increasing demand for viewing high-resolution videos, these parallel tools allow the computer to make full use of the multi-core processors to play these contents smoothly.

D. Frame Prediction

As for Intraframe prediction, HEVC supports 33 angular modes while H.264 only allows 8 different modes. More angular prediction mode brings HEVC higher coding efficiency and is also helpful for getting a smooth sample surface. As for internal Frame prediction, HEVC provides higher compression ratio and picture quality as well as remove redundancy in a video sequence by optimizing the motion prediction.

E. SAO (Sample Adaptive Offset)

HEVC introduces SAO^[6] with the intent to reduce sample distortion, increase the compression ratio, and decrease the bitrate. This new in-loop filtering technique classifies the reconstructed samples into various categories based on BO (Band offset) and Eo (Edge offset) to get an offset for each category, and then add that offsets to each sample of each category. The adoption of SAO averagely receives 2% to 6% save in bitrate with only a 2% increase in the consumption of decode/encode resources.

2) Test Data: HEVC VS MP4 H.264

A. Save Storage Bits: HEVC > H.264

• One minute of 1080p HD, 60fps H.264 video takes up around 175MB storage space on your iPhone.
• One minute of 1080p HD, 60fps HEVC video occupies 90MB storage space on your iPhone.

B. Save Bandwidth: HEVC > H.264

• Around 32Mbps of bandwidth is required to stream 4K broadcast.
• Approximately 15Mbps of bandwidth is needed to stream the same content.

C. Popularity: H.264 > HEVC

• Despise that many people use both H.264 and HEVC, overall H.264 user is twice as that of HEVC users.
• The majority of editing software can't decode HEVC correctly.

D. Quality: HEVC > H.264

• HEVC delivers better picture quality when the given bitrate is the same with the MP4 H.264 clip.
