Every video editor has been there. You filmed the perfect clip at 60fps, you line up the slow motion beat drop, you drop Twixtor on the clip… and you get that horrible warping. Faces stretch, hands glitch, objects disappear mid frame. It doesn't matter how much you adjust the settings, it never looks quite right. That's why more creators every month are searching for 5 Alternatives for Twixtor that deliver smooth slow motion without the headaches.

For 15 years Twixtor has been the default name for frame interpolation, but it was never built for modern creators. A 2024 survey of 1200 independent editors found that 68% experience unusable artifacts with Twixtor on at least one out of every four projects. It's also expensive, unnecessarily complicated, and gets slower with every update. In this guide we break down every viable option, who each tool is for, and exactly when you should stop using Twixtor for good.

1. Built-In Optical Flow: The Zero Extra Cost Twixtor Alternative

Most people don't realize they already have a very capable slow motion tool sitting right in their editing software. Both Adobe Premiere Pro and DaVinci Resolve include native optical flow frame interpolation, and recent updates have closed the quality gap with Twixtor dramatically. For 70% of common use cases, most viewers will not be able to tell the difference between optical flow output and Twixtor.

This works best for clips with consistent movement, clean backgrounds, and no fast camera pans. You won't get the advanced masking controls that Twixtor offers, but for most social media clips, b-roll, and hobby projects this is more than enough. Best of all, there's no extra subscription fee, no plugins to install, and it renders directly inside your timeline without exporting intermediate files.

Before you write this option off, try these adjustments first:

• Render clips at full resolution before applying speed changes
• Add 1-2 frames of motion blur manually after slowing footage
• Avoid slowing footage beyond 20% original speed for best results
• Use Resolve 18.5 or newer, as it received a major optical flow overhaul

The biggest downside here is performance. Optical flow will render slower than Twixtor on most systems, and it still struggles with overlapping objects. If you only do slow motion once or twice a month though, this is absolutely the first alternative you should test before spending any money.

2. Time Remapper 3: Best Mid-Tier Plugin For Professional Editors

Time Remapper 3 is the fastest growing Twixtor competitor right now, and for good reason. Built by a small team of former VFX artists, this plugin was designed specifically to fix the most common complaints people have about Twixtor. It works natively in Premiere Pro, After Effects, Final Cut Pro and DaVinci Resolve.

Unlike Twixtor which locks most advanced controls behind extra menus, Time Remapper puts all adjustment sliders right on the main interface. You can adjust motion sensitivity, edge detection and warp strength in real time while scrubbing your timeline. Most editors report that they can get a clean slow motion shot 3x faster with this plugin than they can with Twixtor.

Here's how it stacks up directly against Twixtor on core features:

Feature	Time Remapper 3	Twixtor Pro
One time cost	$79	$329
Maximum speed reduction	1%	0.1%
Auto masking	Yes	Extra $99 addon

This is the best pick for working editors who use slow motion regularly but don't want to pay Twixtor's premium price tag. The only real downside is that it does not support 360 degree footage, and it has slightly worse performance on very old computer hardware. For 9 out of 10 professional editors though, this will be a straight upgrade.

3. Slowmo Labs: Best Browser Based Option For Quick Social Clips

If you don't edit full time and just need to slow down one clip every now and then, Slowmo Labs is perfect for you. This is a fully browser based tool, meaning you don't have to download anything, install plugins, or even have editing software installed on your computer. Just upload your clip, drag the speed slider, and export.

Despite running entirely in your browser, Slowmo Labs uses the same optical flow algorithm that most desktop plugins use. It can slow footage all the way down to 5% original speed without choppy frames, and it automatically adds natural motion blur to avoid that unnatural robotic look that many free tools produce.

Using Slowmo Labs only takes three simple steps:

1. Upload your video file up to 4GB in size
2. Adjust the speed slider and toggle motion blur on or off
3. Export directly to MP4 at up to 4K resolution

You can process 3 clips per month completely free, or pay $9 per month for unlimited exports. There is no watermark even on the free plan. This is not the right tool for long form video or commercial projects, but for TikTok, Reels or one off clips it beats every other option on this list for convenience.

4. Flowframes: Best Free Open Source Twixtor Alternative

For creators on a zero budget, Flowframes is the best kept secret in slow motion tools. This is completely free open source software with no paywalls, no watermarks, and no hidden limits. It works on Windows, Mac and Linux, and it supports every common video file format.

Flowframes uses AI frame interpolation, which actually produces cleaner results than Twixtor for many types of footage. Instead of just guessing where pixels will move, it trains on each individual clip to predict movement far more accurately. Many action sports editors now prefer Flowframes over Twixtor for fast moving footage like skateboarding and motocross.

There are a couple of important tradeoffs to know about. First, it runs as a separate program, so you will have to export your clip, process it, then import it back into your editor. Second, it does require a fairly modern graphics card to run at reasonable speeds. You can still run it on CPU only, but render times will be very long.

Even with those limitations, this is an incredible option. There is literally no catch, no fine print, and no forced upgrades. If you can't afford any paid tools at all, this is without question the best free option you will find anywhere online.

5. RSMB Super Slow Motion: Best For Motion Blur Quality

Most people know Revision Effects for their famous RSMB motion blur plugin, but very few people know they also make a full frame interpolation tool. This is the most underrated option on this list, and it is the preferred choice for many high end commercial and film editors.

What sets this tool apart is motion blur handling. Twixtor and every other alternative tend to produce sharp, unnatural looking frames when slowing footage down. RSMB Super Slow Motion adds physically accurate motion blur during the interpolation process, resulting in footage that looks like it was actually filmed at high frame rate.

This plugin also works seamlessly alongside the standard RSMB motion blur plugin that most editors already own. If you already pay for the RSMB suite, you already have this tool included at no extra cost. It supports speed changes all the way down to 0.5% original speed, and it has full support for 10 bit and 12 bit professional video formats.

The only downside is the learning curve. This tool has very granular adjustment settings, and you will need to spend a few hours learning how to tune them properly. Once you master the controls though, you can produce better results than any other tool on this list.

At the end of the day, there is no perfect one size fits all replacement for Twixtor. Every tool on this list makes different tradeoffs for price, speed, quality and convenience. If you already own Premiere or Resolve start with built in optical flow first. If you edit professionally go with Time Remapper 3. If you just need a quick social clip use Slowmo Labs. If you have no budget use Flowframes. And if you care most about motion blur quality go with RSMB.

Before you pay for any new tool, test out at least two of these options first. Almost every tool on this list has a free trial or free tier that you can test with your own footage. Save this guide, share it with your editor friends, and next time you reach for Twixtor stop and try one of these alternatives first. You might be shocked how much better your footage can look.
