Post production and professional media
Features and trends
Modern post-production workflows need to handle two significant requirements: i) to import content coming from many sources including different file formats, codecs, and cameras; and ii) to export very high quality video formats needed by the next generation of media applications including Ultra HD (4K and 8K) resolution, High Frame Rate (HFR), high bit depth, etc.
Traditionally the final exports have been done using uncompressed formats (e.g. DPX) or lightweight compressed formats (e.g. Apple ProRes, Avid DNxHD, or GoPro CineForm). As the master file sizes generated by these formats may become too large for emerging high quality applications, advanced video compression tools in post-production workflows are needed.
The HEVC video coding standard, in particular its Fidelity Range Extensions, fulfills all the requirements for professional media with sufficient compression.
Although not as an intermediate codec for editing, HEVC is very well suited for exporting very high quality master files at moderate bit rates.
It supports features such as:
- Professional chroma formats: 4:2:2, 4:4:4, RGB
- High bit depth: 10- and 12-bit
- Intra-only compression
- Transfer function and color gamut metadata
