Spesifikasi YouTube Shorts Saat Ini (2026)

Lihat tabel spesifikasi di atas untuk persyaratan resmi YouTube Shorts. Per Agustus 2026, Shorts harus vertikal (9:16) atau persegi (1:1) dengan durasi maksimal 3 menit. Resolusi yang direkomendasikan adalah 1080x1920 (vertikal), dengan ukuran file maksimal 256 GB atau 12 jam (batas unggah umum YouTube). Format yang didukung meliputi MP4 (H.264 + AAC-LC/Opus), MOV, AVI, WebM, dan lainnya. Unggah dengan frame rate sesuai rekaman (umumnya 24 - 60 fps).

Ekspor Klip yang Cocok untuk YouTube Shorts

Atur resolusi ekspor ke 1080x1920 (9:16) untuk Shorts vertikal layar penuh.
Pastikan video di bawah 3 menit. Untuk iklan Shorts, hanya 60 detik pertama yang tampil di feed Shorts.
Gunakan format MP4 dengan video H.264 dan audio AAC untuk kompatibilitas terbaik.
Frame rate sebaiknya sesuai sumber; 24, 30, atau 60 fps adalah standar.
Gunakan bitrate sekitar 8 Mbps untuk 1080p SDR di 24 - 30 fps; hingga 12 Mbps untuk 48 - 60 fps.

Caption dan Safe Zone untuk Shorts

YouTube akan membuat caption otomatis untuk bahasa yang didukung, dan Anda juga bisa mengunggah file caption sendiri (SRT, SBV, dll). Jika menambahkan caption langsung pada video, posisikan di tengah dan jauh dari tepi — elemen UI YouTube (judul, channel, tombol aksi) bisa menutupi teks di bagian bawah atau kanan. Tidak ada panduan safe zone resmi; selalu uji tata letak sebelum publish.

Tempelkan video atau podcast, biarkan AI memilih momen terbaik, dan ekspor dengan spesifikasi yang tepat — siap diunggah. Selalu cek ulang pengaturan ekspor Anda agar sesuai sebelum publish.
