Part 1. Why Convert HEVC/x265/H.265 to MP4?
Part 1. Why Convert HEVC/x265/H.265 to MP4?
HEVC (x265, H.265, MPEG-H Part 2) is the most popular successor to the widely used AVC (H.264 or MPEG-4 Part 10). HEVC is able to maintain the same video quality at half the bitrate as AVC MP4. Therefore, it's widely used in ultra HD video compressions up to 8K UHD. You may get videos labeled with H.265, HEVC, and x265(x265 is an open-source HEVC encoder designed to encode videos into H.265/HEVC).
While HEVC files are twice compressed as MP4 videos, H.265 is far less compatible than AVC. Many popular devices still don't support the HEVC codec yet or have trouble handling HEVC videos. For example, Adobe Premiere Pro won't import HEVC from iPhone properly and Microsoft doesn't provide support for HEVC codec. HEVC also requires significant computational resources, making it hard to open HEVC videos on older devices. So it is necessary to convert HEVC/x265 to MP4.

Both software and hardware encoders are available, such as x264, x265, and hardware encoders (AMD VCE, Intel QSV, NVIDIA NVENC). Therefore, users can convert a HEVC/H.265 video to MP4 H.264 at different speeds and with different file sizes.
It's packed with basic and advanced features to let users convert videos to almost all presets for all types of platforms, crop, add filters (deinterlace, denoise, sharpen, etc.), customize encoding quality and speed, and do more. The most common handbrake complaint is the sacrifice in user-friendliness, which makes it hard to get started for beginners.
How to Convert HEVC/x265 Videos to MP4 with HandBrake?
Step 1: Download, install, and open Handbrake HEVC to MP4 transcoder. Then click File or Folder to import the source H.265 MKV file.
Step 2: Under Presets, open the dropdown menu > choose a profile. Handbrake will select Generally Fast 1080p30 by default. If the source HEVC is in 4K or higher resolutions, you can go to Web or Devices to convert the 4K HEVC/X265 video in MP4 at 4K. Then under the Summary tab, choose the "MP4" container at the output setting area.

Step 3: Under the Video tab, you can further customize the conversion. First, select an encoder for MP4. You can convert HEVC to MP4 in H.264, H.265, and MPEG4. The VCE and NVENC hardware encoders are faster than the x265/x264 software encoder. However, the VCE and NVENC hardware encoders only support 1-pass mode. AMD VCE, Intel QSV, and Nvidia NVENC are good choices on less powerful computers when dealing with HEVC/H.265 encoding and decoding.

Step 4: Click the "Browse" button to select a destination folder to save the transcoded MP4 file. Press the "Start Encode" icon to begin the H.265/HEVC to MP4 (H.264) transcoding process.

Warm Prompt: Someone is searching for an HEVC video converter for mobiles to decode and re-encode x265 to MP4 H.264 on Android or iDevices. Forget this. If your tablet or phone is too old for decoding and playing back x265 HEVC footage, it will perform even worse in decoding and re-encoding x265 files. Your energy and time will be badly saved only when you conduct x265 to MP4 conversion tasks on a more powerful PC using a GPU hardware accelerated HEVC video converter!
Part 3. FAQs
1. Is HEVC MP4 or MP4?
HEVC aka. H.265 is a video codec to encode and decode digital video. While MP4 is a video container format most commonly used to store video and audio data, codecs, and other metadata. HEVC can be encoded in MP4 container format as well as other container formats. In addition to HEVC, MP4 can also be packaged with MPEG4, H.264, MPEG2, etc. By saying converting HEVC to MP4, we usually refer to change the container format encoded in HEVC to MP4, or re-encode MP4 HEVC to MP4 encoded in other video codecs.
2. How can I convert HEVC to MP4 on Windows?
There are many Windows comaptible HEVC to MP4 converters that can make this job done, like WinX Video Converter, HandBrake, CloudConvert, VLC and more. Take WinX Video Converter as an example:
- Free download WinX Video Converter on your Windows PC.
- Drag and drop to import your source MKV video into the program.
- Choose MP4 Video (h264+aac) as the output format.
- Tap the RUN button to start converting HEVC to MP4 immediately.
3. How do I open HEVC videos for free?
HEVC codec in Microsoft store is charged. Thus, installing HEVC codec on your Windows PC is not the good choice for opening videos for free. Never mind. You can turn on third-party media players like 5KPlayer and VLC. The former has no need to install extra HEVC codec packs, and the later allows to install HEVC codec without a fee.
