The H.265 codec is a video compression standard designed to reduce the amount of data needed to transmit or store digital video. H.265 is also known as HEVC, or High Efficiency Video Coding. In other words, the HEVC codec and H.265 refer to the same compression standard.
Like earlier codecs, H.265 removes redundant visual information rather than sending every part of every frame in full. It uses more advanced compression methods than H.264, allowing video to be represented more efficiently while maintaining useful image quality.
Where H.265 Gains Compression Efficiency
H.265 can analyze larger and more flexible areas of an image than H.264 and uses improved methods for predicting similarities within and between frames. This allows the encoder to describe many scenes with fewer bits.
The practical result is that H.265 can generally deliver a similar visual quality at a lower bitrate than H.264. That can reduce the bandwidth needed to transmit video and the storage required to record it. The benefit becomes especially relevant as resolution, frame rate, or the number of video streams increases.
Greater compression efficiency comes with a tradeoff: H.265 typically requires more processing power to encode and decode. System designers need to consider both communications efficiency and available processing resources.
H.265 vs. H.264
The H.265 vs H.264 comparison is primarily a trade-off among compression efficiency, processing requirements, and compatibility. H.265 can reduce bitrate for a specific level of image quality, which can be useful over constrained communications links or when a few high-resolution feeds must be carried at once.
H.264 remains widely supported and generally places a lighter processing load on the system. It may be preferred when compatibility with existing cameras, decoders, recorders, or displays is a priority.
A video platform that supports both codecs gives integrators more flexibility. The codec can be selected according to the resolution, available bandwidth, latency requirements, processing capacity, storage needs, and receiving equipment for a particular application.
Where Maris-Tech Uses H.265
Maris-Tech supports H.265 across video-processing platforms for defense, surveillance, drones, vehicles, and intelligence-gathering applications. Depending on the product, H.265 can be used to encode camera inputs, decode incoming streams, record video, or transmit compressed feeds over IP networks and communications links.
Efficient compression is particularly useful where high-quality video has to travel over a bandwidth-limited link. It can also help when a compact platform is handling several video streams or higher-resolution imagery, and the available network capacity must be used carefully.
H.265 is one part of the larger video encoding and decoding process. The codec determines how video is compressed and reconstructed, while the complete video chain also includes capture, processing, transmission, decoding, and display. For a deeper look at the standard’s bandwidth and defense applications, see Maris-Tech’s HEVC Video Compression glossary page.

Frequently Asked Questions
What is the H.265 codec?
H.265 is a video compression standard that reduces the amount of data required to transmit or store video. It was developed after H.264 and provides greater compression efficiency.
Is H.265 the same as HEVC?
Yes. H.265 and HEVC, or High Efficiency Video Coding, are two names for the same video compression standard.
How does H.265 compare to H.264?
H.265 generally achieves comparable visual quality at a lower bitrate, while H.264 typically requires less processing and offers very broad compatibility with existing video equipment.
