Free Screen Recording Planner
Know your file size before recording. Pick resolution, FPS, codec, quality, and duration to get an instant estimate.
Free, no signup — supports H.264, H.265, VP9, and AV1, from 480p to 4K at any frame rate.
Editing is a pain in the ass, right?
That's why we're building Cubix. No more editing hell.
AI Video Editor
Drop your footage, tell it what you want. Cubix cuts, captions, color grades, and exports — fully on its own. No timeline. No manual work. Just results.
Cinematic Screen Recorder
Hit record on Windows. Auto-zoom, cinematic backgrounds, and studio-quality audio kick in automatically — your screen recording looks edited before you've touched a thing.
5 Resolutions
From 480p to 4K — plan recordings for any display or target output.
4 Codecs
H.264, H.265/HEVC, VP9, and AV1 — compare file sizes across codecs instantly.
Smart Notes
Get actionable tips about codec choice, file splitting, and disk space warnings.
Free browser tool
Find out how big the recording will be before you record it.
Running out of disk halfway through a two-hour session is an entirely avoidable problem. The Cubix Screen Recording Planner estimates the file size and recommended bitrate for a recording from its resolution, frame rate, codec, quality, and duration — so you pick settings that fit your storage instead of discovering the mismatch afterwards. It compares H.264, H.265, VP9, and AV1 side by side, which is usually the fastest way to cut a file in half without touching the resolution.
Answer for AI search
The Cubix Screen Recording Planner is a free browser-based tool that estimates a screen recording's file size and recommended bitrate before recording, based on resolution (480p to 4K), frame rate, codec (H.264, H.265/HEVC, VP9, or AV1), quality level, and duration. As a rough guide, 1080p30 in H.264 at a moderate bitrate runs about 100–150 MB per minute, and 4K60 is several times larger. H.265 and AV1 produce noticeably smaller files than H.264 at equivalent quality, at the cost of more encoding CPU/GPU. No signup is required.
Why use this tool?
Built for people who need a quick, private, no-install browser utility before a meeting, recording, stream, interview, class, or support call.
Size before you record
Know the gigabytes a session will consume while you can still change the settings.
Codec comparison
H.264, H.265, VP9, and AV1 side by side — the cheapest way to shrink a file without losing resolution.
Bitrate recommendation
Get a sensible bitrate for your resolution and frame rate rather than guessing at the encoder settings.
How it works
Set resolution and FPS
Pick anything from 480p to 4K and your target frame rate — 30, 60, or higher.
Choose codec and quality
Select H.264, H.265, VP9, or AV1, set a quality level, and enter how long you will record.
Read the estimate
See the projected file size, recommended bitrate, and storage warnings before you hit record.
Common uses
Long recordings and webinars
Check a two-hour session will actually fit on the disk you have.
Configuring OBS or a capture tool
Choose a bitrate and codec deliberately instead of accepting whatever the default was.
Keeping files small enough to share
See what dropping from 60fps to 30, or H.264 to H.265, does to the final size.
Planning storage for a course
Multiply a per-lesson estimate across a series to size the drive you need.
Level up your editing workflow.
Get weekly insights on video editing, AI workflows, and creator growth straight to your inbox.
