How to Convert HEVC/H.265 to H.264 with Lossless Quality

H.265 codec, also referred to as High-Efficiency Video Coding (HEVC), is video compression standard that was designed for the newest generation of high-resolution video. Compared to H.264, this newer standard offers from 25% to 50% better data compression at the same level of video quality. Additionally, H.265/HEVC supports resolutions up to 8192×4320, which includes 8K UHD as well. Despite of this, H.265 is still less common than its predecessor (H.264) in the industry. That's why many people are looking for ways to convert H.265 to H.264 from time to time. In this article, we will share with you the top two H.265 to H.264 transcoders and illustrate how to change HEVC to H.264 without quality loss. Also we'd like to share you with the pros and cons of H.265 compared with H.264.

Best HEVC/H.265 to H.264 Converters

Part 1. H.265 vs. H.264: Which One Is Better? Why We Need to Convert HEVC to H.264?

When you examine the technology behind these two codecs, you can easily conclude which one wins in our article on H.264 vs. H.265. You’ve guessed it — it's HEVC!

H.265 is more advanced than H.264 because of various reasons. The biggest difference here is that H.265/HEVC allows for further reduced file size of your live video streams. This significantly lowers the required bandwidth.

Then, another perk of H.265 is the fact that it processes data in coding tree units. Although macroblocks can go anywhere from 4×4 to 16×16 block sizes, CTUs are able to process up to 64×64 blocks. This enables H.265 to compress information more efficiently.

Additionally, H.265 also has an improved motion compensation and spatial prediction than H.264 does. This is quite helpful for your viewers in that their devices will require less bandwidth and processing power to decompress all information and watch a stream.

However, bear in mind that H.265 is still less common than its predecessor (H.264) in the industry. Below are two disadvantages of H.265 compared with H.264:

1. H.265 is not that compatible as H.264. For instance, GoPro 4K HEVC videos are not friendly to many editor apps. Namely, H.265/HEVC is not widely applied in many product fields so far, except a few devices and media players like iPhone 6/later, Windows 10, VLC, etc.

2. H.265 may be superior to H.264 in the next 5 or 10 years along with the popular application and streaming of 4K UHD resolution, but right now if your gadget's resolution is up to 720p/1080p, H.264 is more suitable.

In conclusion, if you want to deliver the best quality video in the smallest possible format, then you should go with H.265/HEVC. However, HEVC is highly acclaimed esp. in the era of 4K 8K Ultra HD while H.264 still dominates now, which makes H.265 to H.264 conversion sensible.
