Video Editing Build Calculator
Score your PC for video editing: 1080p to 8K timeline playback, render time estimates and codec support for H.264, H.265 and ProRes.
What matters for video editing
Video editing is really three different jobs, and each rewards different hardware: playing back a timeline smoothly, applying effects, and exporting the finished file. A machine can be excellent at one and disappointing at another.
Storage is the most underrated component
4K footage at high bitrates needs sustained read speed, and multi-camera projects multiply that by the number of angles. Editing directly from a hard drive causes dropped frames during playback regardless of how strong the processor is. A fast NVMe scratch disk transforms the experience more than most CPU upgrades. Compare drive types with the SSD Speed Comparison.
Hardware encoders changed export times
NVENC on NVIDIA cards, and the equivalents from AMD and Intel, encode H.264 and H.265 in dedicated silicon. Exports that once took an hour on the CPU now take minutes. Quality per bit is slightly behind a slow software encode, but for delivery to YouTube or a client the difference is negligible against the time saved.
Codec matters more than resolution
H.265 and 10-bit 4:2:2 footage from mirrorless cameras is far harder to decode than the same resolution in a mezzanine codec like ProRes. If timeline playback stutters, transcoding to proxies usually fixes it more effectively than any hardware upgrade.
Memory: 32 GB is the working figure
16 GB works for 1080p. 32 GB is comfortable for 4K with a reasonable number of layers. 64 GB matters for 8K, heavy After Effects compositions and long-form multi-camera projects. Beyond that, returns fall off quickly for most editors.
VRAM for effects and grading
GPU-accelerated effects, noise reduction and colour grading all consume video memory, and DaVinci Resolve in particular is demanding. 8 GB is the practical minimum for 4K work and 12–16 GB removes most of the friction.
Frequently asked questions
Do I need a powerful GPU for video editing?
A mid-range card with a modern hardware encoder covers most editing. Where the GPU really earns its place is GPU-accelerated effects, noise reduction and colour grading - DaVinci Resolve in particular leans on it heavily.
How much RAM do I need for 4K editing?
32 GB is the comfortable working figure. 16 GB is usable but you will meet its limits with several layers or effects. 64 GB is worth it for 8K or heavy compositing.
Why does my timeline stutter on a fast PC?
Usually the codec rather than the hardware. Highly compressed camera footage such as 10-bit H.265 is expensive to decode. Generating proxies or optimised media fixes this far more reliably than upgrading components.
Is hardware encoding worse quality than software?
Marginally, at the same bitrate. For delivery to YouTube or a client the difference is invisible, and the export is many times faster. Software encoding still wins for archival masters where every bit counts.
Should media and cache be on separate drives?
Ideally yes. Keeping source footage, cache and export target on separate fast drives avoids one drive serving three demands at once, which shows up as dropped frames during playback.
