About this calculator
Video render time depends on duration, frame rate, complexity (effects, color grading, compositing), and machine speed. Rule of thumb: standard 1080p H.264 export on a modern laptop runs ~1× duration. CGI-heavy or 4K output: 5-10× duration. Render farms or GPU acceleration cuts time dramatically. ProRes RAW: faster (less encoding); H.265: slower (more efficient compression).
Frequently asked
GPU vs. CPU render?+
GPU encoders (NVENC, QuickSync) are 5-10× faster than CPU at slightly lower quality. Most editors prefer GPU for drafts, CPU for final.
Why 4K so much slower?+
4K = 4× pixels of 1080p. Render time scales roughly linearly with resolution.
Codec impact?+
H.264: fast, ubiquitous. H.265 (HEVC): 2-3× slower, ~50% smaller files. ProRes: very fast, huge files.
Cloud render farms?+
AWS Render, Pixar Renderman + AWS, Render Network. $0.05-1/core-hour. Worth it for CGI / VFX.
Live streaming render?+
Real-time only (1× speed). NVENC + low-bitrate. Quality lower than offline render.
