Aiarty Video Enhancer 3.8 for macOS

Frame interpolation for slow motion

Most Mac editors already have a quick way to throw a clip into a timeline and slow it down. What they don’t always have is a clean way to generate the missing frames without making the motion look choppy. That’s where Aiarty steps in with frame interpolation that creates AI-generated intermediate frames—smooth 8X and 16X slow motion, the kind you can actually use.

You bring the footage in, let it analyze the motion, and it builds the in-between frames. The result isn’t just a slowed-down clip; it’s a new sequence that holds up when you drop it back into your editor. It feels like a utility that sits between your raw footage and your timeline, doing one specific job well without asking you to rethink your whole workflow.

Snags people trip over and how to fix them

Every app has a few spots where the wheels squeak. Aiarty's no different. The first one I hear about is the Gatekeeper hurdle on install day. You mount the disk image, drag the app into Applications, and macOS throws up a warning that won't let you open it. The fix is straightforward—open Terminal, type the command the readme gives you, press Enter, and the gate swings open. On Intel Macs, you may also need Rosetta 2 sitting quietly in the background, and sometimes a VPN gets in the way if the app phones home during that first launch.

Another snag is export size. People upscale a thirty-second clip to 4K, turn on frame interpolation, and wonder why the output file lands like a brick. The reality is that AI-generated frames and high-bitrate upscales simply produce large files. If you're tight on disk space, start with a short test clip before committing to a long render. The 512 GB requirement in the specs isn't decoration—this app chews through temporary cache while it works.

Audio denoise occasionally catches people off guard too. It removes background noise well, but if the original track is very thin to begin with, the cleaned result can sound a little hollow. Running the module more than once on the same file doesn't help. One pass at the default settings is usually the sweet spot.

Process audio without touching the video

A few things in Aiarty sit just below the surface and make everyday use smoother once you spot them. The audio denoise module works independently, so you can feed it a video file and only process the sound without touching the picture. That saves time when someone sends you a clip where the video is fine but the room tone is a mess.

The frame interpolation tool remembers your last-used slow-motion factor between sessions. If you're working through a batch of clips that all need the same 8X treatment, you set it once and keep moving. On Intel machines with a dedicated GPU, the CUDA memory optimizations that landed in version 3.8 mean the app now holds larger frame caches without stumbling—less fan noise, fewer pauses mid-export.

MKV support also opened a door that wasn't there before. If your source files come from screen recordings or certain camera rips that use Matroska containers, you no longer need to remux them in a separate tool first. Drag the MKV straight in and let the enhancer get to work.

Resume interrupted upscales

The update that brought Aiarty to 3.8 wasn't flashy, but it tackled a couple of real-world headaches. The biggest one was resumable exports. Before this, if a long upscale job got interrupted—power flicker, cat on the keyboard, whatever—you started over from zero. Now the app picks up where it left off. That matters when you're processing a twenty-minute restoration and the render window says forty minutes remaining.

MKV support arrived in the same update, which removed a small but persistent friction for editors who deal with footage that doesn't come wrapped in MP4 or MOV. Combined with the CUDA memory work on Intel Macs, the app feels less like it's walking a tightrope on older hardware. The render pipeline doesn't get bogged down as easily when you stack denoising, upscaling, and interpolation into one pass.

These changes don't rewrite what the app does. They just make the doing less fragile. That's the kind of update I appreciate—the one that quietly removes reasons you used to swear at your screen.

Bottom line: it’s a pre-editor step for people who want slow motion that doesn’t look like a stutter.

Version 3.8 adds a few practical improvements. You can now pause and resume exports, work with MKV files directly, and the app uses CUDA memory more efficiently on supported hardware.
