AI video editing software falls into three groups, and the choice gets a lot easier once you know which group you belong in. Classic editors with AI features, meaning DaVinci Resolve, Adobe Premiere Pro and Kdenlive, still have you doing the editing; the AI handles side jobs like transcription, captions and reframing. Reel machines like OpusClip and Submagic turn one long video into short clips with animated captions all by themselves, but they barely let you intervene in the cut. In between sit CapCut as a timeline editor with AI buttons and Descript as an editor where you cut the text instead of the audio track. "Free" does not mean the same thing everywhere. Permanently free with no monthly allowance are the open source route, Kdenlive with a locally installed speech model, and the free edition of DaVinci Resolve, which ships without the AI equipment: Blackmagic keeps the AI Neural Engine, auto subtitles and text-based editing included, in the Studio version for a one-off 295 dollars, 305 euros on the German site. CapCut, Descript and OpusClip have permanent free tiers limited by a monthly allowance, a watermark or locked features, and Submagic offers a trial. German gets transcribed everywhere, but it is not served equally well everywhere, Descript for instance removes filler words only in English transcripts according to its own documentation. And none of these programs saves you from having to operate it. All prices in this article: as of September 2026.
I no longer edit my own videos. In my business, editing runs through an AI employee who operates ffmpeg and a locally running Whisper model, and all I do at the end is check the result. I still went through the common programs for this article, because the "with what" question almost always comes before the "who" question. Everything I write about AI at work is collected on the AI page; how I decide what gets handed off at all is in Which Tasks You Can Hand Off to AI.
The six criteria that actually decide it
Tool lists online mostly compare feature lists. That helps little, because every feature list is long. These six questions decide it in practice:
- What does the AI actually take over? For some programs, "AI-powered" means producing a transcript. For others it means independently cutting ten clips out of 40 minutes of raw footage. That difference is measured in hours.
- How well does German work? Nearly all of them transcribe German. The features built on top of that, removing filler words, trimming pauses, finding chapters, are sometimes limited to English.
- Captions: generating, styling, correcting. Every automatic caption tool mishears, especially technical terms and proper names. What matters is how fast you can find and fix the errors.
- Export. Resolution, frame rate, watermark and aspect ratio. In the free tiers this is where the real restriction sits.
- Price and billing model. One-off purchase, monthly subscription, minute allowance or credit system. With a lot of footage, a credit system can end up costing more than a subscription with a fixed number of hours.
- Where the limit is. Every one of these tools has one, and it is rarely on the landing page.
Prices and platforms at a glance
Two things stand out immediately. First: native Linux programs appear twice on this list, DaVinci Resolve and Kdenlive. The browser services OpusClip and Submagic run independently of the operating system, but they process your footage on their servers. If you want to edit on Linux and stay local, that decision is already made for you. Second: the only one-off purchase on this list is DaVinci Resolve Studio. Everything else is a subscription where after three years you have paid more than the Studio licence costs.
What the AI takes over, where German works, where it stops
Where the marketing promises more than the tool delivers
Three points show up on closer inspection, and all three concern exactly the things the tools advertise with.
Descript and filler words. Filler word removal is the most cited reason to use Descript, and it is good. But the documentation explicitly names a set of tools that only work with English transcripts, filler word detection among them. German gets transcribed, English gets cleaned up. If you edit German-language video, you are buying part of a feature set you will never use. On top of that, Descript supports one language per file; mixed-language recordings are not provided for.
DaVinci Resolve and the word "free". Resolve is rightly considered the best free video editor around. Its AI equipment is just not part of that. The vendor's own comparison table lists Voice Isolation, audio transcription, text-based editing, auto subtitles, Magic Mask, Smart Reframe and Super Scale all in the Studio column. If you search for "free AI video editing" and land on Resolve, you get a very good editor, but not the features you were searching for.
The reel machines and video length. Submagic's entry tier caps video length at two minutes, the middle tier at five. That is meant for reels and adequate for them, but it is no use for a webinar or an interview. OpusClip, in turn, needs a long video as input; assembling a reel out of three separate clips is not what the tool is built for. Both vendors also place their free-tier restrictions at the most visible spot possible: OpusClip puts a watermark on the animated captions in the free plan. How the automators hold up on captions alone against editors and local models is in the comparison of subtitle tools for reels.
A fourth point concerns none of the tools individually and all of the browser services on this list: your raw footage gets uploaded. If it contains clients, staff or conversations, that is a decision you should make deliberately. How I handle it is in AI and Privacy: What the AI Gets to See.
Which tool fits which case
- Beginner, phone, quick reels: CapCut. Free version, auto captions included, available on phone and desktop. Watch which templates are marked Pro, otherwise the watermark ends up in your finished export.
- Lots of talking, little picture, podcasts or interviews: Descript, but only with the limitation above in mind. Cutting in the transcript is a different working mode, and for talking-head video it is faster than any timeline.
- One long video, many short ones out of it: OpusClip or Submagic. In this group the AI really makes the cut rather than just assisting.
- Professional, predictable, no subscription: DaVinci Resolve Studio. One payment of 295 dollars, runs on Windows, macOS and Linux, and the AI features come with it.
- You are in the Adobe subscription anyway: Premiere Pro. Speech to Text and text-based editing are included, German is covered through a language pack you install.
- Open source, Linux, everything local: Kdenlive with Whisper. No subscription, no upload, but setup work instead. It is the only fully free open source route in this selection; DaVinci Resolve and Premiere Pro also run on your own machine, while your footage gets uploaded with the browser services OpusClip and Submagic.
Operating a tool or filling a role
All seven programs have one thing in common: they wait for someone to open them. That is the point at which a software comparison stops answering the actual question. If you want to edit three videos a week, your bottleneck is not the program. Your bottleneck is that someone has to review the raw footage, find the pauses, correct the captions, check the format and say at the end: done.
That is why I did not add another piece of software here, I filled a role. Eddi is my AI employee for video editing. He gets raw footage and a script and delivers a finished video: pauses out, captions on, overlays placed, 9:16 format. He does not work in an editing suite, he works on the command line with ffmpeg, a locally running Whisper model for transcription and Remotion for programmed transitions and overlays. And he has a fixed checking routine that did not come out of a manual but out of a complaint from me: after every encode a black frame check, after every cut a comparison of two transcripts.
The difference to everything in the tables above is not the technology. Some of the tools are literally the same. The difference is that the job has an address. A tool has to be operated every single time; a role receives an assignment. How such a role comes about is described in Hiring an AI Employee: The Process, and if you want to see what it is good for first, there are cases in AI Agents: 10 Real-World Examples.
Frequently asked questions
Which video editing software is best for beginners?
CapCut, if you need something finished fast: free version, auto captions included, available on phone and desktop. If you want to learn for the long run and have the time, take DaVinci Resolve in its free edition; the order in which to learn video editing has its own post. That one is free and usable indefinitely, but the AI features such as auto subtitles are missing there.
Is AI video editing really free?
Partly. CapCut, OpusClip and Descript have permanent free tiers that reset every month, but with limits: Descript caps at 60 minutes of media per month and exports in 720p with a watermark, OpusClip puts a watermark on the animated captions, and with CapCut the premium templates, effects, fonts and music are reserved for Pro. Submagic only offers a trial. Permanently and unrestrictedly free is only the open source route, Kdenlive with a locally installed speech recognition model.
Which video editing software runs on Linux?
DaVinci Resolve and Kdenlive. CapCut, Descript and Adobe Premiere Pro do not run on Linux. OpusClip and Submagic run in the browser and are therefore independent of the operating system, though the processing happens on the vendor's servers rather than your machine.
Do the AI features work in German?
Transcription does, in every tool in this comparison. With the features built on top of it you have to look closely: Descript explicitly names filler word detection, transcript import and the glossary as English-only. Premiere Pro needs a language pack installed for German. And automatically generated captions mishear technical terms and proper names in every language, so you have to proofread them.
CapCut or DaVinci Resolve, which is better?
They are different tools. CapCut is fast, runs on your phone and brings auto captions for free; in return you stay inside template thinking and pay $19.99 a month if you want the Pro content. DaVinci Resolve is a full editing suite with a one-off purchase for the Studio version, costs more time to learn, and also runs on Linux.
Will an AI do the whole edit for me?
In this comparison, only in one case: when you have a long video and want short clips out of it. That is what OpusClip and Submagic are built for, and there the AI really does make the cut. In every other case the AI supplies groundwork, transcript, captions, framing, and you make the editing decisions. Whether your case needs an editor at all or a video generator is the better starting point is the question before that.
Where to go from here
Take a video you were going to edit anyway and run it through exactly two of the tools above, one from the timeline group and one from the automation group. After two runs you will know more about your own working mode than after ten comparison tables. If what comes out of it is that your problem is not the program but the repetition, then the next step is a role rather than a subscription: My AI Workforce: Fourteen Employees, One Boss shows how it is divided up at my place. The ready-made templates for it are in my community.
