Why Trim AV1 Files?

AV1 is the newest open-source, royalty-free video codec developed by the Alliance for Open Media (AOMedia) — backed by Google, Netflix, Amazon, Apple, and Meta. AV1 delivers 30–50% better compression than H.264 at the same quality, making it the future of web video. YouTube, Netflix, and Twitch already use AV1 for streaming.

Trimming AV1 files lets you extract clips from AV1 recordings, prepare segments for sharing on platforms that support AV1, or remove unwanted sections from screen recordings and downloads encoded in AV1.

Frequently Asked Questions

What is AV1 format?

AV1 (AOMedia Video 1) is an open-source, royalty-free video codec from the Alliance for Open Media. It offers the best compression efficiency of any widely supported codec — 30–50% smaller files than H.264 at equivalent quality.

Can I compress while trimming?

Yes. Under "File Compression," choose any method. "Constant Quality" (CRF) gives the best quality-to-size ratio for AV1. Note that AV1 encoding is slower than H.264 or H.265.

Can I also resize while trimming?

Yes. Under "Video resolution," change resolution — useful for creating 720p clips from 4K AV1 content for faster sharing.

Should I trim as AV1 or convert to MP4?

Keep AV1 for maximum compression efficiency and web use. For universal device compatibility (especially older devices), AV1 to MP4 with H.264 is safer.

What plays AV1 files?

VLC, Chrome, Firefox, Edge, and most modern Android devices. Older hardware may lack AV1 decode support — check your device's specs.
