HEVC is the next generation compression standard that offers a number of enhancements over H.264. HEVC compression is 50% more efficient than H.264, which translates into maintaining the same video quality at half the bitrate or double the video quality at the same bitrate. Furthermore, H.265 (HEVC) does even better than H.264, supporting video resolution up to 8K 4320p (H264 up to 2160p). What's better, H.265 will save much bandwidth when compressing and streaming 4K/8K videos online. However, HEVC is still not widely supported as H.264. Therefore, sometimes we need to convert H.265 to H.264 for smooth playback, editing or other purpose.

There are many HEVC to H264 converters in the market. Here we single out the best 3 transcoders (free and online included) and illustrate how to transcode GoPro/YouTube/Apple H.265/HEVC video to H.264 without losing any quality.

It is not recommended to use free online video converters to decode H.265/HEVC to H.264 MP4. Most online video converters only support small video files conversion, e.g, lower than 100MB. Besides, The online conversion speed is always like snail speed and the process is not stable, together with poor output video quality and sometimes malware/virus saved along to computer.

Certain Circumstances and Why You Should Convert H.265 to H.264

The reason varies. Sometimes, your device's screen does not support 4K resolution, your hardware configurations fail to support the high-demanding HEVC decoding, the player won't play HEVC videos with 60fps, high bit rates, 4K and higher resolutions, or HEVC is not widely welcomed by most of your devices. Taking compatibility into account, H.265 is far less compatible than H.264 and MP4. For instance, GoPro 4K HEVC videos are not friendly to many editor apps, Adobe Premiere Pro won't import iPhone taken HEVC properly.

Despite H.265 doubled the encoding efficiency, H.264 wins back by its wide compatibility and gains 83% adoptions according to Bitmovin video codec survey in 2021. Here comes many circumstances under which we need H.264 AVC rather than H.265 HEVC codec.

1. Can't play H.265 videos on old devices.

H.265 was standardized in 2013 and the stable version of its encoder x.265 was released in 2016. Before that, TVs, smartphones, and computers were shipped without HEVC support. Aged devices cannot HEVC videos, so you have to transcode them to H.264 which came into being 10 years earlier than HEVC.

2. Can't upload H.265 videos to popular platforms.

Still, many social media platforms do not support videos encoded with H.265. Some of them stop you from uploading H.265 files, and some take it upon themselves to transcode H.264 to H.265 with visible quality loss. If you ever run into the trouble with apps below, convert H.265 to H.264 by yourself in advance.

3. HEVC codec is unfriendly to video editing.

Editing videos in HEVC codec would drive many users crazy with severe lagging or crashing, esp. when rendering the timeline in real time and exporting. That's because HEVC was not born for post editing. It needs 10x computing power than its predecessor H.264/AVC. To solve HEVC codec issues in DaVinci Resolve, Premiere Pro and other video editing software, transcode HEVC to ProRes (for original image quality) or H.264 (for smooth performance).

4. HEVC codec is missing in some players or OS.

Though the media player or the operating system you are using is up to date, there are chances the HEVC codec is missing. For example, HEVC is not natively supported by Windows 11 and Windows 10. Typically, you'll be asked to install an HEVC codec either paid or free. If you don't want to put your PC at risk by installing a code pack, converting it to H.264/AVC is necessary.

Conclusions:

HEVC is highly acclaimed esp. in the era of 4K 8K Ultra HD while H.264 still dominates now, which makes sense to convert H.265 to H.264. Online video converters may be an option, but not the best one owing to the strict size limit (<20MB), instability, poor output quality, and even malware/adware. Thus you need a solid clean and easy-to-use HEVC converter, EaseFab Video Converter will your best pick.
