nCodify is a media encoding and utility app that I write and maintain for internal company use. I adapt and add new features when required, such as HLS stream encoding (for Apple TV and in-app video delivery), U-LAW audio (for automated phone messages) and more.
In the past, I have adapted it to achieve broadcast-compliant IMX and XDCAM encoding for advert/programme delivery, as well as ProRes encoding on Windows-based PCs when support from other encoding software was more limited.
Video Encoding
- H264 - efficient compression and choice of software or hardware encoder
- H265
- VP8/VP9 (WebM)
- Apple ProRes (up to 4:4:4 10-bit)
- Avid DNxHR (up to 4:4:4 10-bit)
- Animated GIF creation and optimisation
- Audio editing only (video passthrough)
- Muxing and demuxing of container files to edit video/audio separately
- Subtitle track muxing (up to 9 tracks per video file)
- Subtitle hard coding ('burn in') whilst encoding video
- Video frames to still images with configurable time/frame number pattern
- Simultaneous multi format encoding (H264, H265, VP9), developed specifically for embedding video on web pages
- Rotation options to correct orientation (e.g. smartphone video)
- Highly configurable encoding options, ships with multiple presets for different use cases and device targets
Video Streaming
- HLS H264 transport stream encoding, Apple TV compliant
- Automatic handling of playlist and metadata files
- Used to encode in-app tutorials for Affinity Photo for iPad and all video content for Affinity TV app on Apple TV
Image Encoding
- JPEG - Extremely efficient encoding
- JPEG Multi Resolution output - quickly generate 1x, 2x, 3x, 4x, 5x and 6x images at configurable resolutions from one input file
- PNG - efficient 8-bit dithered encoding
- PNG Multi Resolution output - as with JPEG option, quickly generate 1x, 2x, 3x, 4x, 5x and 6x PNGs.
- PNG Enhancer - designed specifically to enhance GUI screenshots for print. Enhance local contrast, tonal shift (to avoid "yellowing" during CMYK conversion), fine detail sharpening
- TIFF & TGA output
- Unprocessed RAW - used for analytical purposes. Extract greyscale RAW data before white point remapping, demosaicing, colour space conversion and tone mapping
- GIF Optimisation - further optimise animated GIFs
- EXIF data rewriting - infrared white balancing, 360 metadata injection
Filters
- Deinterlacing with several implementations - field blending (e.g. 60i > 30fps), field interpolation (e.g. 60i > 60fps), adaptive kernel, motion compensated, neural network
- Accurate colour space conversion and white point adaptation
- Debanding (Average Pixel & Gradient)
- Pre-scale blurring (for compression efficiency/reduce aliasing)
- Pre-scale sharpening
- 3D/Wavelet denoising
- Post-scale sharpening
- Deblocking and deringing for compressed source material
- DCT denoising (image encoding only)
- Flip/flop orientation
- Audio normalisation, loudness normalisation, limiter, EQ and advanced 18-band EQ
Audio Encoding
- WAV (up to 192kHz, 64-bit)
- AAC (up to 320kbps)
- FLAC
- MP3 (up to 320kbps)
- ALAC (Apple Lossless)
- U-LAW (for encoding automated phone messages). Configure extension and headerless file writing
- Dynamic normalisation (compressor + limiter) available for all audio formats
