Shotcut's own documentation describes the Default export preset two different ways. The Shotcut User Guide, whose cover is dated June 2026, says the built-in default values create a "high quality" H.264 MP4. The FAQ, answering which preset to use, labels the same preset "moderate quality H.264". Both pages sit on shotcut.org, and neither one attaches a CRF value or a bitrate to that description.
So if you arrived looking for a number, here is the honest answer up front: the official pages describe Default in words, not figures. Below is exactly what each page says, plus the one release note that lets you place Default relative to another stock preset.
The two descriptions, at a glance
| Question | What the official pages say |
|---|---|
| How does the User Guide describe it? | The default values create "a high quality H.264 MP4 file at a reasonable size and speed" |
| How does the FAQ describe it? | "Default (moderate quality H.264)" |
| Do you have to pick a preset at all? | No. The guide says "It is not necessary to choose a preset!" |
| How do you get back to it? | "Clicking Reset or the preset named Default restores the panel to its default values." |
| Is Default the top quality setting? | A release note for 25.01.25 says H.264 High Profile defaults to a higher quality than "YouTube or the defaults" |
| What CRF or bitrate does it use? | Not given on either page — check the official documentation |
What the User Guide says
The relevant passage is a note in the Export Basics section, and it is worth reading in full because it covers more than the quality wording:
"NOTE: It is not necessary to choose a preset! Shotcut comes with default values that creates a high quality H.264 MP4 file at a reasonable size and speed that automatically adapts to the resolution, frame rate, and visual complexity of your project. Clicking Reset or the preset named Default restores the panel to its default values."
Three things in that sentence do real work. First, the defaults are described as adaptive — the guide ties them to your project's resolution, frame rate and visual complexity rather than to one fixed setting. Second, "high quality" is paired with "a reasonable size and speed" in the same breath, so the guide is describing a balance. Third, Reset and the Default preset are the same destination, which is useful if you have been clicking through presets and want a clean slate.
What the FAQ says
The FAQ entry is structured as a list of use cases. It opens by refusing to name a single winner:
"It all depends; that is why there are so many of them! But here are some suggestions:"
Two of its lines matter here. For a video-sharing site, it points elsewhere:
"Upload to a video-sharing web site: H.264 High Profile or YouTube"
And Default appears only in the self-hosting line, with the parenthetical that started this whole question:
"Put onto my own web site: WebM and/or Default (moderate quality H.264)"
That is the same preset the User Guide calls high quality, described in the FAQ as moderate. Neither page walks the other back, and neither supplies a figure you could use to reconcile them.
The one release note that ranks Default
Shotcut's release notes give a single relative data point. For Release 25.01.25:
"Export preset H.264 High Profile now defaults to a higher quality 65% than YouTube or the defaults."
Read it carefully. It tells you that, as of that release, H.264 High Profile's quality percentage sits above the defaults — which is consistent with the FAQ steering uploads toward H.264 High Profile rather than Default. It does not tell you what percentage the defaults use. That number is simply not on the pages, and anyone quoting you a CRF equivalent for Shotcut's quality slider is not quoting Shotcut.
What to do when the difference matters
For most projects, the practical move is the one the FAQ already spells out: if the file is going to a video-sharing site, use H.264 High Profile or the YouTube preset rather than Default. If you are hosting it yourself, the FAQ puts Default and WebM in that slot.
Where people get into trouble is the next step — opening Advanced to hand-tune what Default was doing for them. The guide is unusually blunt about that:
"Click Advanced to show many more controls and options. However, by clicking Advanced you should understand that Shotcut expects you to be advanced and know what you are doing. There are simply too many combinations of settings and options that Shotcut's advanced export mode lets you create invalid combinations and does not protect you from yourself."
There is also a detail in the guide's section on creating your own presets that reframes the whole question. Describing what you are editing when you save one, it says: "The preset is really a list of thing to change from the defaults." In other words, every stock preset is defined against the same default values the Default entry restores — which is why the wording used for those defaults matters more than it looks. If you do build one, the guide notes presets live as files in the presets > encode folder inside the app data directory, that you can share them, and that "You must restart Shotcut after manually adding preset files in order for Shotcut to see them."
If your goal is simply a smaller file that still looks right, you do not have to re-export from the editor at all. You can take the file Shotcut already produced and re-encode just that:
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
This runs in your browser tab — the video is read from disk, re-encoded locally and handed back, so nothing is uploaded. It is the quickest way to compare a Default export against a smaller version without rendering your whole timeline twice. If you want the reasoning behind the knobs, the video compressor page walks through them, and all Clapr tools covers the rest.
Gotchas that outlive the preset you pick
A preset is not a guarantee. The User Guide lists what presets are not: "Project templates Guaranteed-safe configurations Automatically compatible with all codecs or hardware encoders". It adds, for the example configurations it publishes: "Using presets assumes you understand the implications of the selected settings."
The hardware encoder checkbox can override the preset's codec. In the guide's words: "Presets may include hardware encoders. However, the Use hardware encoder checkbox will still affect which codec is used unless you choose a hardware codec that Shotcut does not manage, for example ProRes." So a Default export with that box ticked is not the same encode as a Default export without it.
A bigger file from the hardware encoder is expected, not a fault. The guide's own nuance box reads: "Hardware encoding is usually less compression-efficient, not lower quality." It also notes the visual difference is often small or invisible, with the difference showing up in bitrate efficiency.
Processing Mode sits underneath all of this. Release 25.12.30 added Settings > Processing Mode, and the note says plainly: "This affects both preview and export."
FAQ
Is Shotcut's Default export preset high quality or moderate quality? Both words come from Shotcut. The June 2026 User Guide says the default values create "a high quality H.264 MP4 file at a reasonable size and speed"; the FAQ lists the same preset as "Default (moderate quality H.264)". The official pages do not reconcile the two, and neither gives a figure.
What CRF or bitrate does the Default preset use? Neither the User Guide passage nor the FAQ entry states one. Third-party conversions between Shotcut's quality percentage and CRF are not from Shotcut — check the official documentation before relying on any number.
Which preset should I use for YouTube? The FAQ answers this directly: "Upload to a video-sharing web site: H.264 High Profile or YouTube". Default appears in the self-hosting line instead.
Do I need to choose a preset before exporting? No. The User Guide says "It is not necessary to choose a preset!" and describes the built-in defaults as adapting to your project's resolution, frame rate and visual complexity. Clicking Reset, or the preset named Default, restores those values.
My Default export came out larger than I expected — did I do something wrong? Check whether the hardware encoder is on. Shotcut's guide says hardware encoding is "usually less compression-efficient, not lower quality", so a larger file at the same quality target is documented behaviour rather than a fault.
