Can I convert a horizontal video to vertical without cropping?

Yes. Choose the 9:16 aspect ratio (1080×1920) and select the blurred background fill. Your original wide video stays sharp and uncropped in the center, while a matching blurred copy fills the top and bottom margins, meeting vertical platform standards without cutting out subjects.

Why does converting MOV to MP4 finish so quickly?

When your MOV file already contains standard H.264 video and AAC audio, Beat2Cut performs a lossless stream copy into the MP4 container. Because pixels and audio samples are repackaged rather than decoded and recompressed, the transfer completes in seconds with zero loss of picture quality.

How does constant frame rate conversion fix audio sync drift?

Variable frame rate (VFR) footage from phones and screen recorders records fewer frames during still moments, causing desktop editing suites to lose synchronization over time. Converting to constant 30 fps or 60 fps gives every frame the same duration, ensuring picture and sound stay locked together throughout your timeline.

What are the duration and credit limits for video conversion?

Each successful conversion costs 5 credits from the 100 free credits you get every month after signing in, so about 20 conversions a month cost nothing; Pro includes them. A failed or cancelled job is never charged.

Convert video to MP4, WebM, or 9:16 vertical — Example result

Beat2Cut converts video containers, aspect ratios, and frame rates right in your browser without uploading your media. Switch between MP4, MOV, WebM, or extract the audio to WAV and M4A. Reframe landscape clips into vertical 9:16 formats for TikTok and Shorts using blurred borders. Each conversion costs 5 credits from the 100 a free account gets every month, and is covered by Pro.

When your source file already uses compatible video and audio codecs (such as H.264 video inside a QuickTime MOV container switching to MP4), the converter copies encoded media packets directly without recompression. This container remuxing process finishes in seconds, and keeps the original picture untouched. Full re-encoding only engages when you change codecs, alter aspect ratios, or convert frame rates.

Social distribution frequently demands vertical 9:16 (1080×1920) or square 1:1 (1080×1080) framing for platforms like Reels, TikTok, and Instagram. When aspect ratios differ, you can choose between three fill modes: a soft blurred background that preserves the full image without cropping people, standard black letterboxing bars, or a centred crop that fills the frame edge to edge.

Smartphones and screen recording utilities frequently output variable frame rate (VFR) media to conserve storage during static scenes. When imported into desktop editing software, VFR files cause severe audio drift and creeping sync errors. Converting your clip to a constant 30 fps or 60 fps locks frame intervals to an exact clock, curing sync drift before you begin cutting.

Processing and export rendering occur entirely inside your browser memory. For massive 4K footage on mobile devices or laptops with limited RAM, browser memory constraints may interrupt long jobs. A modern release of Chrome, Edge, Safari, or Firefox is required. Each export uses 5 credits from your 100 monthly allowance, while Pro subscribers convert without limits.

Export MP4 (H.264/AAC), MOV, WebM (VP9/Opus), or extract audio directly to M4A and WAV.
Reframe to 9:16, 16:9, 1:1, or 4:5 with blurred background fill, letterbox fit, or crop.
Changing only the container copies the stream without re-encoding; constant 30 or 60 fps fixes variable frame rate.
