Should I use CQP or CBR for OBS recording?

CQP for recording, CBR for streaming — always. CQP (constant quality) spends bits where the scene needs them, so calm menus stay small and chaotic fights stay clean. CBR wastes space on easy scenes and starves hard ones; it exists for streaming because Twitch needs a predictable pipe, not because it looks better.

What CQP value should I use in OBS?

CQP 18–20 is the sweet spot for 1080p60 gameplay: clean enough to edit and upload with files around 5–9 GB per hour. Use CQP 16 for archival footage you'll grade later, CQP 21–23 when disk space matters more than pixel perfection. Same scale as CRF — lower is better and bigger.

Which encoder should I use in OBS: NVENC, x264, or AV1?

NVIDIA owners: NVENC H.264 (or NVENC AV1 on RTX 40-series and newer for ~30% smaller files). AMD: AMF H.264. Intel Arc or recent Core: Quick Sync H.264. Apple Silicon: VideoToolbox HEVC. No discrete GPU or plenty of spare CPU: x264 on veryfast. AV1 gives the smallest files but needs modern hardware on both ends.

Why are my OBS recordings so large?

Usually CQP set too low (16 or below), recording at 4K with no downscale, or CBR at a huge bitrate. Move to CQP 20, cap output resolution to what you deliver (usually 1080p60), and expect roughly 5–9 GB per hour at 1080p60 — normal and correct for editable footage. Shrink for upload afterward, not during recording.

What are the best OBS settings for recording 1440p 60fps?

Canvas and output at 2560×1440, 60 FPS, NVENC H.264 at CQP 18–20 (or NVENC HEVC at the same CQP for ~40% smaller files). MKV with auto-remux to MP4, two AAC audio tracks at 320 kbps. Expect 12–20 GB per hour. 1440p60 also earns YouTube's higher-bitrate VP9 treatment over 1080p uploads.

Best OBS Recording Settings in 2026 (Quality Without Huge Files)

Q: Should OBS record to MKV or MP4?

MKV. If OBS crashes or power fails, the MKV up to that second is recoverable; an interrupted MP4 is corrupt and the whole recording is lost. Enable Settings → Advanced → Recording → Automatically remux to MP4 so every recording converts itself to an editable MP4 on stop — crash safety plus compatibility.

Q: Why is my OBS recording laggy or dropping frames?

If OBS reports encoder overload, the encoder — not your game — is choking: switch to a faster preset (NVENC P5→P3, x264 veryfast→superfast), cap output to 1080p60, or close GPU-heavy background apps. If the game stutters but OBS is fine, cap in-game FPS or enable Game Mode so the game stops starving the encoder. Recording overload is never a network problem — that's streaming-only.

Q: What is constant QP in OBS?

Constant QP (CQP) holds the quantization parameter steady so every frame gets the quality it needs — it is OBS's name for constant-quality rate control. x264 calls the same mode CRF and AV1 encoders call it CQ. CQP 16 means archival quality, 18–20 everyday recording, 21–23 space-saving. It is the best rate control for recording in OBS.

Q: Does OBS have a CRF setting?

Not by that name — OBS hardware encoders label constant-quality mode CQP instead of CRF, but it works the same way (lower is better and bigger). If you're following an FFmpeg/HandBrake guide that says CRF 20, set CQP 20 in OBS. The x264 encoder in OBS also uses CRF terminology in some builds.

Three settings decide 90% of your recording quality: the encoder, the rate control, and the format. Get those right and everything else is garnish. Here are copy-paste settings for 1080p60, 1440p, and 4K — plus the mistakes that ruin most recordings.

Right after recording

Your settings are dialed in. Now the files are huge.

1080p60 at CQP 18–20 is supposed to land at 5–9 GB per hour — that is correct for footage you intend to edit. The cleanup comes after: remux the whole folder to MP4, compress a copy for upload, and pull the highlight audio. Formatif Pro does that in one batch, on your machine, without uploading a 40 GB session.

Rule #1: CQP for recording, CBR for streaming

The single most common OBS mistake is recording with streamer settings. CQP (constant quality) spends bits where the scene needs them — calm inventory menus stay tiny, chaotic team fights stay clean. CBR (constant bitrate) forces the same bitrate everywhere: it wastes gigabytes on easy scenes and starves hard ones. CBR exists because Twitch needs a predictable pipe — not because it looks better. For local recordings there is no pipe, so there is no reason to use CBR.

CQP uses the same scale as CRF (see our compression guide): lower is better and bigger. CQP 18–20 at 1080p60 lands around 5–9 GB per hour — normal and correct for footage you intend to edit.

CQP, CQ, CRF, constant QP — decoding the labels

These are the same constant-quality idea under different names, which is why searching “CRF in OBS” confuses people: OBS hardware encoders label it CQP (constant QP — the quantization parameter held steady), x264 calls the same mode CRF, and AV1 encoders call it CQ. Whichever label your encoder shows, the best rate control for recording in OBS is this constant-quality mode — CQP 16 for archival (huge files, maximum latitude), CQP 18–20 for everyday recording, CQP 21–23 when disk space matters. The best rate control OBS offers for recording has never been CBR; CBR is the streaming answer to a different question.

Rule #2: use the hardware encoder you already own

GPU encoding (NVENC, AMF, Quick Sync, VideoToolbox) looks as good as CPU encoding at recording bitrates while barely touching the processor your game needs. x264 on veryfast is the fallback when the GPU is maxed or absent — never use ultrafastunless you enjoy blocky footage; it's dramatically worse per bit.

AV1 recording (NVENC AV1 on RTX 40-series and newer, AMD VCN AV1, Intel Arc) cuts file sizes ~30% at equal quality — worth it for 4K or tiny SSDs, provided whatever edits and plays the files supports AV1 (all modern editors and YouTube do; older phones and TVs may not).

Best OBS settings for recording 1440p 60fps

1440p60 is the sweet spot between sharpness and sanity: canvas and output at 2560×1440, 60 FPS, NVENC H.264 at CQP 18–20 (or NVENC HEVC at the same CQP for ~40% smaller files if your editor handles HEVC). Expect roughly 12–20 GB per hour — double 1080p60, half of 4K. Everything else on this page applies unchanged: MKV + auto-remux, two audio tracks, CQP never CBR. Only step up to full 4K recording if you crop or zoom in editing; for straight uploads, 1440p60 also earns YouTube's higher-bitrate VP9 treatment over 1080p.

Rule #3: MKV + auto-remux, and split your audio

Record MKV so a crash never eats a session, and enable Settings → Advanced → Recording → Automatically remux to MP4 so every file converts itself on stop. Full walkthrough with screenshots logic in our MKV to MP4 methods guide.

Then fix the mistake you'll regret in editing: in Settings → Output → Audio, record at least two tracks — game/desktop on track 1, microphone on track 2 — at 320 kbps AAC. One mixed track means you can never lower the game under your voiceover later. Two tracks cost almost nothing and save edits.

Don't confuse recording with streaming settings

Streaming settings (CBR 6–8 Mbps, keyframe every 2s, tuned for Twitch) exist to survive the internet. Recording settings (CQP 18–20, MKV, multi-track audio) exist to preserve quality on your disk. Running one profile for both jobs guarantees bad results at one end — keep two profiles in OBS and switch between them.

Quick fixes for the three classic failures

“Encoder overloaded” / rendering lag

The encoder is choking: drop one preset step (NVENC P7→P5, x264 medium→veryfast), cap output at 1080p60, close GPU-heavy background apps. If the game stutters but OBS is calm, the game is starving the encoder — cap in-game FPS.

Files are enormous (20 GB+ per hour)

CQP too low, 4K with no downscale, or CBR at streaming-plus bitrates. CQP 20 + 1080p60 output is the reset button. Shrink for upload afterward — never during recording.

Recording won't open / editor rejects it

MP4 corrupted by an interrupted session (switch to MKV + auto-remux), or an editor that dislikes the codec (Premiere vs MKV/AV1 quirks — remux to MP4 or transcode a mezzanine). See the MKV to MP4 guide for every fix.

After the recording stops

A recordings folder that manages itself.

Settings dialed in, clips pile up: 40 GB of MKVs, Vogons of multi-track audio, filenames like 2026-09-04_21-33-11.mkv. Formatif Pro ($8.95 one-time) turns the folder into finished files overnight — remux to MP4, compress to upload size, extract highlights' audio — offline, in batch, with per-file status instead of a 3 a.m. failed queue.

OBS recording questions, answered

Should I use CQP or CBR for recording?

CQP, always. CBR is a streaming constraint (predictable pipe for Twitch), not a quality choice. Recording has no pipe — use constant quality.

What CQP value should I use?

18–20 for 1080p60 gameplay (~5–9 GB/hr). 16 for archival, 21–23 when disk space matters. Lower = better and bigger.

Should OBS record to MKV or MP4?

MKV + auto-remux to MP4. Crash-proof recording, editable files, one checkbox. Never raw MP4.

NVENC, x264, or AV1?

NVENC H.264 by default (RTX 40+: NVENC AV1 for ~30% smaller). AMF/Quick Sync/VideoToolbox per your hardware. x264 veryfast as fallback — never ultrafast.

Why is my recording laggy?

Encoder overload: faster preset, 1080p60 cap, close GPU hogs. Game stutter with calm OBS: cap in-game FPS. Recording lag is never network.

Why are my recordings so large?

CQP too low, 4K output, or CBR overkill. Reset to CQP 20 + 1080p60, then compress for upload afterward.

What is constant QP in OBS?

OBS's name for constant-quality rate control (x264 calls it CRF, AV1 calls it CQ). 16 archival, 18–20 everyday, 21–23 space-saving.

Does OBS have a CRF setting?

Not by name — hardware encoders label it CQP, same behavior. A guide's CRF 20 equals OBS CQP 20.

Best settings for 1440p 60fps?

2560×1440, 60 FPS, NVENC H.264 CQP 18–20 (or HEVC for ~40% smaller). MKV + auto-remux, dual AAC tracks. ~12–20 GB/hr.
