Bitrate
Bitrate is the amount of data processed or transferred per second, expressed in bits per second (bps). In audio and video, bitrate determines quality and file size. A higher bitrate means better quality but larger files. Bitrate can be constant (CBR) or variable (VBR).
Codec
A codec (coder-decoder) is software or hardware that compresses (encodes) and decompresses (decodes) media files. Codecs make large audio and video files smaller for storage and streaming while keeping quality. Popular video codecs include H.264, H.265/HEVC, and AV1.
Cycles
Cycles is Blender’s path-tracing render engine that simulates light in a physically realistic way. It computes global illumination, realistic shadows, reflections and refractions by tracing light paths, making it well suited for high‑quality final renders and productions where physical accuracy matters. Cycles can run on CPU and GPU (CUDA, OptiX, HIP, Metal depending on platform) and supports advanced features like subsurface scattering, caustics, volumetrics and denoising, but it is generally slower than real‑time engines like Eevee. Because it integrates tightly with Blender’s material node system, Cycles is a key tool in 3D modeling and shading pipelines for photoreal output.
Eevee
Eevee is Blender’s real-time render engine designed for fast, interactive rendering of 3D scenes. Rather than path tracing, Eevee uses rasterization together with screen-space effects, shadow maps, and light probes to approximate lighting, shadows, and materials. This makes Eevee ideal for look-dev, previews, and animation iteration in 3D modeling and production, but less physically accurate than Cycles for final renders that require correct global illumination or caustics.
OBS Studio
OBS (Open Broadcaster Software) Studio is free, open-source software for video recording and livestreaming. It supports multiple sources (screen, webcam, capture cards), scenes, filters, and effects. OBS is widely used by streamers, content creators, and for professional broadcasts.
