To encode faster in TMPGEnc Video Mastering Works, you must optimize your hardware acceleration settings, select the correct speed presets, and bypass unnecessary video filters. Adjusting these core options can increase your rendering performance by up to ten times without causing noticeable loss in quality.
Follow this organized guide to maximize your encoding speeds: 1. Enable Hardware Acceleration (The Biggest Speed Booster)
By default, the software may rely entirely on your CPU. Switching decoding and encoding processes to your graphics card or processor’s built-in media engine will drastically shorten render times.
NVIDIA NVENC / CUDA: Go to Preferences > CPU/GPU. Check NVIDIA CUDA or NVENC and click enable. This allows your GeForce graphics card to handle heavy codecs like H.264, H.265 (HEVC), and AV1.
Intel Quick Sync / oneVPL: If you use an Intel processor, ensure Intel HD Graphics or oneVPL drivers are active. This offloads processing onto the CPU’s integrated media engine. 2. Lower the Encoder Speed Preset
Every codec template contains a speed-versus-compression scale. The slowest options work much harder to analyze video redundancies to save minor bits of data.
Select Fast or UltraFast: In the Output Settings, change the performance preset to Fast, Very Fast, or UltraFast (depending on whether you are using x264 or x265).
The Trade-Off: “UltraFast” or “Super Fast” options render up to 10x faster and take a massive load off your CPU. The file size will be slightly larger, but the visual difference is often completely unnoticeable. 3. Switch to Single-Pass (CRF / CQ) Mode
Multi-pass encoding forces the program to scan through your entire video file twice before it even starts writing the final data, effectively doubling your wait time.
Use Constant Quality (CQ) / Constant Rate Factor (CRF): In your rate control settings, switch from 2-Pass VBR to Constant Quality (CQ) or CRF.
Why it works: It achieves the exact target quality you specify in a single pass, making it significantly faster while adapting bitrates efficiently across complex scenes. 4. Minimize Visual Filters
Every active filter forces the software to recalculate pixels on every single frame before compressing the clip.
Avoid Complex Denoising: The Video Noise Reduction filter is exceptionally taxing. Avoid it unless your source footage is severely degraded.
Turn off unused effects: Ensure that unneeded color corrections, sharpness adjustments, or blur masks are toggled off in your clip editing panel. 5. Adjust Environmental & System Priorities
You can tell your Windows operating system to give TMPGEnc absolute dominance over your system’s resources.
Raise Task Priority: Navigate to Options > Environmental Settings > CPU. Locate the priority sliders and change them to High. This forces your CPU and RAM to prioritize the rendering pipeline above background Windows tasks.
To tailor this process for you, what version of the software are you running, and what video format (e.g., MP4, MKV) are you converting? TMPGEnc Mastering Works – Very Slow vs Very Fast
