Best Video Formats: MP4, AVI, MOV, MKV

Picking a format is about compatibility, quality, and file size—not magic codecs alone.

Creators bounce between phones, editors, and social apps. The wrong container wastes time. Here is a practical comparison.

MP4

Best everyday choice. H.264/H.265 + AAC works almost everywhere: phones, browsers, Instagram, TikTok, YouTube.

MOV

Common from Apple devices and pro cameras. Excellent quality, but less universal on Android and some web players.

AVI

Older Windows-era container. Still appears in archives, but bulky and outdated for social uploads.

MKV

Flexible for archiving (multiple audio/subtitle tracks). Convert to MP4 before most social posts.

Recommendation

• Share & social: MP4
• Apple-heavy workflows: MOV masters → MP4 exports
• Long-term archive with tracks: MKV
• Legacy files: convert AVI → MP4

Conclusion

Default to MP4 for delivery. Keep masters in the highest practical quality, then export MP4 for distribution via Unvidio when you need a portable copy of permitted media.
