✂ Without Conversion Stream copy ▼
Cut without re-encodingAllows you to cut any video or audio file(s) by changing input and output point from the right panel. If it's a video file with a highly compressed codec (like H.264), the cut will be automatically on the nearest keyframe.
Replace audioAllows you to replace audio track(s) on a video. Drop your video first then your audio file(s) — they will be added in the same order as the list. You can switch between video and audio files to perform multiple replacements.
RewrapAllows you to change your media container. Only works if the output container supports the source codec. Very useful for changing your video timecode or mapping audio tracks differently.
ConformAllows you to change the framerate metadata. This function does NOT solve the VFR problem; you must convert your file in this case.
MergeAllows you to concatenate all the files from the list to one output. All your files need to have the same codec, resolution, framerate and audio settings.
ExtractAllows you to extract any stream from your file(s).
SubtitlingOpens the subtitling tool. This function will create an .srt file next to your input file location.
Video insertsAllows you to insert clip(s) into a video that references the same timeline — just like a digital video tape insert. This allows you to produce a video that maintains the encode of the unmodified part(s).
Example: On a 52min video you need to edit a part from 00:26:00:00 to 00:26:30:00. Add the master file and your video inserts to the file list and start the function. The algorithm will automatically insert the clips from timecodes without any compression.

⚙ Settings ▼
🖼 Image / Scale ▼
ScaleChoose a scale or write your own. The AI models use the ESRGAN algorithm, which requires extracting each image into a temporary folder. Make sure you have enough space on your hard drive; you can choose the extension for the temporary files.
  • Adapt — Adds black bars if source input is different from the selected scale.
  • Stretch — Stretches your media to the selected scale.
  • Crop — Removes excess pixels from the source according to the selected scale.
Do not upscale lower resolutionsIf the source scale is smaller than the selected output scale, it will not be scaled.
RotationRotates your file(s) with the selected angle.
MirrorFlips your files horizontally.
Force displayChanges the display aspect ratio. You can write your own value, e.g. 20:9 or 2.39
Create an image sequence from a videoOutputs each frame from your video at the selected framerate (custom value supported).
📈 Bitrates Adjustment ▼
Video bitrateSelect or write the video bitrate in kilobytes per second.

  • CQ — Constant Quality (also known as CRF)
MaximumLimits peak bitrate in complex scenes.
Audio bitrateSelect or write the audio bitrate in kilobytes per second.
File sizeChoose the desired output file size in megabytes. The encoder will attempt to reach the desired value but cannot guarantee a perfect size. The lock icon makes all files in the list share the same output file size.
2-passRun a 2-pass encoding for better quality — especially useful at low video bitrates.
Max. QualityConfigures each codec to get the maximum quality possible. For example, with H.264 the command -preset veryslow is sent. Also check 2-pass with low video bitrate encoding.
🎵 Audio Settings ▼
Mix audio filesAllows you to mixdown your audio files from the list to one output. The audio mapping is shown when the list is empty.
Separate audio tracksSplits each audio track into an independent file.
Change the sample rateAllows you to change the audio sample rate.
Convert from / toAllows you to change audio as a video framerate. The audio pitch is maintained while audio is stretched.
ConvertConverts the audio stream to the selected settings. Make sure your output container supports the selected audio codec.
Audio 1–16Handles the audio mapping — you can remove tracks or edit the audio order. Very useful with the Rewrap function to change audio mapping only without re-encoding.
OffsetControls the audio offset in images per second.
✂ Cropping / Overlay / Subtitles / Watermark ▼
CroppingAllows you to crop the image from a preset or custom values.

🎨 Colorimetry & Color Grading ▼
Gamma levelAllows you to change the gamma value from 1.8 to 2.6.
Convert levelsAllows you to convert video levels between 16–235 and 0–255 using ffmpeg's scale video filter.
Convert colorspaceAllows you to convert colorspace using ffmpeg's video filter. HDR → SDR conversion uses a LUT instead for better results and better encoding speed.
ColorspaceAdds colorspace metadata to your file(s). For output video codecs this option also sets video quantification.
Apply a LUTApplies a LUT to your video file(s) according to ffmpeg's lut3d filter. You can add or remove LUTs using the manage button.
Color gradingAllows you to color correct your file with numerous settings.
🔧 Corrections ▼
Stabilize imageAnalyzes the video then stabilizes it using the ffmpeg vidstab filter.
DeflickerAdds an overlay of the same input video delayed by 1 frame with 50% opacity. Useful for hard repetitive flickering.
Reduce bandingReduces non-smooth gradients using ffmpeg's deband filter.
Limit output to 16-235Limits the output video levels to TV levels.
DetailsAdds or removes details using ffmpeg's smartblur filter. Works great to remove aliasing artifacts.
Noise suppressionReduces video noise using ffmpeg's nlmeans filter. This filter can use GPU if you use Vulkan.
Exposure smoothingSmooths out variable luminance changes using ffmpeg's deflicker filter. Works great for timelapse uses.
🎞 Transitions ▼

Fade-out audioApplies an audio transition to the end of your file(s) with selected settings.
🎞 Image Sequence ▼
Activate the image sequenceSorts all files by number and uses them to output a video from images. This option does NOT convert the frame rate — use the Conform checkbox instead.
Frame blendingEach multiple of 'x' frames is blended between them to create smooth motion. Great for timelapse uses.
Add motion blurAdds motion blur by doubling framerate with interpolation then blending created frames to keep original framerate. Works best combined with frame blending.
🔍 Filter ▼
FilterAllows you to keep only files from the selected range. This option reads metadata with exiftool.
🧪 Advanced Features ▼
Force outputForces output video levels to full range (0–255) or video range (16–235) on metadata.
Force profileAllows you to choose encoding parameters related to the video codec. By default Shutter Encoder uses high 5.1 even when unchecked.
Force presetAllows you to choose encoding parameters related to the video codec. Max. quality checkbox uses for example veryslow preset for H.264 codec.
Force tune / quality / speedAllows you to choose encoding parameters related to the video codec.
Enable fast startMoves video header info to the beginning of the file for best streaming performance.
Set GOPAllows you to set a fixed Group Of Pictures.
Set to Open-GOPOnly check it if you're using Open-GOP videos.
Remove duplicate framesRemoves redundant frames according to ffmpeg's mpdecimate filter.
ConformFramerate conversion with several modes:
  • Reverse — Encodes the video backwards at the selected framerate. Warning: requires memory to buffer the entire clip, so trimming is suggested.
  • Speed — Encodes the video at the selected framerate speed while maintaining audio pitch. Changes original video duration.
  • Drop — Removes extra frames without changing duration. Must be a multiple of 2 for best results, e.g. 50i/s to 25i/s.
  • Blending — Blends two frames to make a new one and achieve the selected framerate. Avoids video stuttering with framerate conversions — fast to compute.
  • Interpolation — Creates new frames using ffmpeg's minterpolate filter. Best option for small framerate changes in terms of quality.
  • Ultra-slowmotion — Creates interpolated frames to the selected framerate then plays at the original framerate.
Force to progressiveForces progressive scan. Can be useful for Progressive Segmented Files videos. This option does NOT apply a deinterlace filter.
Force deinterlacingApplies a deinterlacing filter and ticks force progressive checkbox.
  • bwdif — Motion-adaptive, edge-directed deinterlacer derived from BBC research. Higher quality than yadif with better motion handling.
  • yadif — Fast, basic motion-adaptive deinterlacer. Widely supported but lower quality on complex motion.
  • estdif — Edge-slope-tracing deinterlacer. Prioritizes diagonal detail preservation over motion accuracy.
  • w3fdif — High-quality motion-compensated deinterlacer using spatial-temporal filtering. Very clean but slower.
  • detelecine — Detects and reverses telecine (e.g. 3:2 pulldown) to restore original progressive frames. Not a true deinterlacer.
  • advanced — Intel Quick Sync hardware deinterlacing with motion-adaptive and motion-compensated modes. Quality depends on GPU generation.
Force interlacingEncodes your file(s) with interlaced metadata. If your input video is 50p (or 59.94p or 60p) it creates true interleaving — odd frames via the first image, even frames via the second image — to output a real 50i (or 29.97i or 30i).
Force fields inversionAllows you to switch from BFF to TFF fields.
Enable alphaKeeps the alpha channel if available from your video input.
Preserve folder hierarchyRecreates folder hierarchy from input file to output destination.
Preserve metadataAdds all available metadata from source files to output: recording date, camera model, etc.
Preserve subtitlesKeeps input captions of your video. Make sure the output container supports it.
Generate formatSpecial formats:
  • OP-Atom — Creates media for Avid Media Composer using hexadecimal naming and bmxtranswrap tool. The destination can be directly outputed to "Avid MediaFiles/MXF/1". If a new card is detected from the files list, numbered folder will be incrementeded. When you'll open Avid Media Composer, an .mdb file should appears in each folder to drop it to your bin.
  • OP1a — Creates OP-1a format files with .mxf extension.
  • AS-10 — Creates AS-10 format files thanks to bmxtranswrap with 8 audio tracks.
  • AS-11 — Creates AS-11 format files thanks to bmxtranswrap with 8 audio tracks.
Source in OP-Atom formatKeeps only .mxf files in Shutter Encoder's list then uses an algorithm to bring together video with audio files.

📊 Status Bar & GPU ▼
🖥 GPU Decoding ▼
GPU decodingGPU decoding is not always faster than CPU! Only use the "auto" or "none" options unless you really know what you're doing.
  • Pros — When the GPU is selected, it only works on specific codecs: H.264, H.265, VP8, VP9, AV1, MPEG-1 and MPEG-2. If the input codec is different, it will not use your GPU. Less CPU consumption because of GPU processing. If you're using GPU encoding without any filters or corrections, you get a significant boost to use GPU as decoding also. You should get pretty good advantages when using GPU decoding with editing codecs like DNxHR, ProRes etc. (because GPU decode and CPU encode).
  • Cons — The CPU must always send data to the graphics processor; therefore, if you are using corrections (such color correction, denoise or whatever) the result could be slower because of CPU transfers + CPU filters.
  • Conclusion — This option has been thoroughly tested; using "auto" mode should give you the best results most of the time. If you see artifacts or black images, select the "none" option.
