If you've ever recorded gameplay, captured your screen, or shot video on your phone and then brought it into Final Cut Pro, DaVinci Resolve, or Premiere, you may have noticed something strange — the footage stutters, the audio drifts out of sync, or the timeline just feels wrong. The culprit is almost always variable frame rate video, and it's one of the most common problems that content creators on Mac run into.
How to fix variable frame rate video on Mac
The solution is to transcode your VFR footage to CFR — constant frame rate — before bringing it into your editor. This converts the variable spacing into perfectly even frames that your editing software can handle correctly.
Using Migaki
Migaki is a native macOS app built specifically for this problem. Drop your VFR footage into the Video drop zone, click Start, and Migaki automatically detects the variable frame rate, chooses the right conversion method, adjusts the audio track to stay perfectly in sync, and verifies the output quality before you ever open it in your editor.
The key difference is what happens to the audio. Most tools either ignore the audio timing when converting VFR to CFR — causing drift — or they drop frames to compensate. Migaki calculates the exact tempo adjustment needed and applies it to the audio track so every frame and every audio sample stays locked together throughout the entire clip.
It also runs a Quality Verifier on every export that re-reads the output file so you know the conversion worked before you waste time editing footage that's still broken.
How to tell if your footage is VFR
When using Migaki, simply open your video clip in the editor and look at the video info. There it will state the FPS of your video. If it is not a standard FPS such as 24, 30, or 60, but some weird number like 28.65 ~ thats VFR.
What frame rate should I convert to?
For most content creators the right answer is 30fps for YouTube, Twitch clips, and social media. If you're working with cinematic content, 24fps is standard. If your source was captured at 60fps and you want to keep the smoothness, convert to 60fps CFR.
Migaki lets you set the target frame rate per file and automatically selects the nearest clean standard frame rate based on your source — so a 29.97fps source gets conformed to a clean 30fps without you having to think about it.
The bottom line
Variable frame rate footage is fixable. The key is transcoding to CFR before you edit, and making sure the tool you use handles audio sync correctly. Once your footage is in CFR your editor will treat it like any other clip — no stuttering, no drift, no surprises.
