- Utilizes low-complexity, high-speed intra-frame encoding exclusively, avoiding pixel-domain prediction[1]
- Capable of real-time encode and decode operations at resolutions up to 8K.
- Engineered as an intermediate codec tailored for video editing rather than for distribution purposes.[2]
- Optimized to leverage parallel processing on multi-core CPUs and GPUs.
- Supports advanced chroma subsampling formats including 4:2:2 and 4:4:4.
- Compatible with bit depths from 10 up to 16 bits.
Adoption
- Incorporated in Android 16
- Supported by FFmpeg
- Embedded in Samsung Galaxy flagship models beginning with the Galaxy S26 series.
- Utilized by leading video editing software platformsTemplate:Fix/category[clarification needed] as an intermediate codec solution.
Technical specifications
APV treats every frame as an independent still image, much like Motion JPEG and Apple ProRes. This contrasts with distribution-focused codecs such as H.265 and AV1, enabling faster encoding and decoding speeds—particularly on multi-core processors where frames can be handled concurrently—albeit with a trade-off in compression efficiency.
Frames are segmented into macroblocks, each encoded separately with individual bitstream offsets. While this method decreases compression efficiency, it facilitates parallel encoding and decoding within a single frame, enhancing performance on multi-core CPUs.
Within each macroblock, further division into 8x8 blocks occurs. These blocks undergo encoding through DCT followed by entropy coding, paralleling techniques used in Motion JPEG and Apple ProRes.
Intra prediction is confined to operate solely inside each macroblock to enable parallel processing across macroblocks. Notably, unlike typical video codecs, intra prediction targets DC coefficients rather than pixel data, which lowers processing demands.
To minimize artifacts along DC block borders, APV applies a deblocking filter.
According to Samsung, APV delivers approximately a 20% enhancement in compression efficiency at equivalent visual quality compared to an unspecified professional video codec implementation. Furthermore, Samsung asserts that APV provides superior quality encoding relative to the I-frame-only mode of H.265 on smartphones, where the complexity of H.265 restricts achieving high bitrates. This improvement in quality is accompanied by a substantially larger file size.[2]
