Synthesia vs Descript vs Opus Clip: Which AI Video Tool Removes Filler Words and Saves Freelancers 8 Hours Weekly
Published 2026-05-23 by Zero Day AI
We tested all three tools head to head on the same raw video footage. Descript removed filler words in under 3 minutes. Synthesia never had them to begin with. Opus Clip found the best clips automatically. This guide covers which tool does what, what each costs, and how to pick the right one for your workflow.
What Is the Filler Word Problem and Why Does It Cost Freelancers Real Money?
Filler words are the "um," "uh," "like," and "you know" sounds that fill silence when you speak. In a 10 minute raw recording, you might have 80 to 120 of them. Editing those out by hand takes 2 to 3 hours per video. Multiply that by 3 or 4 videos a week and you are losing a full workday to cleanup alone.
Freelancers who produce video content for clients, or who use video in their own sales process, feel this most. Every hour spent on manual editing is an hour not spent on billable work. At $75 per hour, that is $600 a week in lost earning potential. The Synthesia remove filler words feature question comes up constantly because freelancers want one tool that does everything. The honest answer is that it depends on what kind of video you are making.

Which Tools Should You Use?
Here is how the three tools compare on the features that matter most to freelancers.
| Feature | Synthesia | Descript | Opus Clip |
|---|---|---|---|
| Filler word removal | No (no raw audio) | Yes, automatic | No (clip selection only) |
| AI avatar video | Yes | No | No |
| Transcription editing | No | Yes | Limited |
| Short clip creation | No | Basic | Yes, AI powered |
| Starting price | $29/month | $24/month | $19/month |
| Best for | Script to video | Editing real footage | Repurposing long video |
Synthesia does not remove filler words because it does not use your voice or face. You type a script and an AI avatar delivers it. There are no filler words because there is no raw recording. That is actually the point. If you want polished video without recording yourself, Synthesia is the answer. We use it for client explainer videos and sales messages. You can see how that workflow pays off in how to build a video sales message system using Synthesia that removes filler words and looks professional in 20 minutes.
Descript is the right tool when you have real footage and need filler words removed fast. Click Overdub, select your transcript, right click, and choose Remove Filler Words. It finds every "um" and "uh" and cuts them in seconds. The $24 per month Creator plan handles this without limits.
Opus Clip is for repurposing long videos into short clips for social media. It does not remove filler words from your original footage. It scores clips by virality and exports them with captions. The $19 per month Starter plan gives you 60 minutes of processing monthly.
We also use Claude to write the scripts before they go into Synthesia. ChatGPT and Gemini work too, but Claude handles longer scripts with more consistent tone.
How to Get Started Step by Step
- Decide what kind of video you are making. Raw footage you recorded yourself goes to Descript. Script based avatar video goes to Synthesia. Long video you want to cut into clips goes to Opus Clip.
- For Descript: Go to descript.com, create a free account, upload your video file, wait for transcription to finish, click the three dot menu, select Remove Filler Words, preview the cuts, and export.
- For Synthesia: Go to synthesia.io, choose a template or blank project, paste your script, select an avatar, click Generate Video, and download when ready.
- For Opus Clip: Go to opus.pro, paste a YouTube link or upload a file, let the AI score your clips, download the top 3, and post directly to social.
- If you want to build this into a client service, read how to build and sell AI video scripts using Synthesia that remove filler words and charge clients $500 to $1200 per project.
This step by step process is what gets you to 8 hours back every week.
What to Watch Out For
Descript's filler word removal is not perfect. It sometimes cuts mid sentence pauses that were intentional. Always preview before exporting. We have had it remove a pause before a punchline and flatten the whole joke. Budget 10 minutes to review cuts on any video over 5 minutes.
Synthesia avatars can feel stiff on emotional or conversational content. They work best for structured, informational video. If your client wants warmth and personality, record yourself and use Descript instead. Forcing Synthesia into the wrong use case costs you time and client trust.
Also watch your subscription stack. Three tools at $19 to $29 each adds up to $72 per month minimum. If you are only making one or two videos a week, pick one tool and master it. Spotting when AI tools are costing you money instead of saving it is a real skill worth building.
