Frame size, Custom size and pixel aspect ratio in Export

Applies to 0.11Updated 6 Nov 20262 min read

Choose a frame size from Premiere’s list or type your own, set the pixel aspect ratio for anamorphic exports, and pick from the new presets.

In Export, Frame Size sets the size of the file and Pixel Aspect Ratio sets how wide its pixels show, as in Premiere Pro.

Frame Size

• Match Sequence
• Horizontal: 8K UHD (7680 × 4320, only for HEVC and ProRes), DCI 4K, 4K UHD, QHD 1440p, DCI 2K, HD 1080, HDV / HD Anamorphic (1440 × 1080), HD 720, qHD, SD Widescreen (854 × 480), NTSC DV, PAL DV, SD 4:3 and 640 × 360.
• Vertical and Square: 4K Vertical 9:16, Vertical 9:16, Vertical 720, Portrait 4:5 and Square 1:1.
• Custom…

A custom size

Choose Custom…. The list shows the size, for example Custom (1000 × 500), with blue W and H numbers under it. Drag them, or click to type. The lock between them keeps the shape when you change one. Click the lock to set them separately.

• Sizes are kept even, because encoders need it, from 16 to 8192.
• H.264 can't write a size over 4096. A warning under the size says to choose HEVC or ProRes.

Pixel Aspect Ratio

Premiere's eight: Square Pixels (1.0), D1/DV NTSC (0.9091), D1/DV NTSC Widescreen 16:9 (1.2121), D1/DV PAL (1.0940), D1/DV PAL Widescreen 16:9 (1.4587), Anamorphic 2:1 (2.0), HD Anamorphic 1080 (1.333) and DVCPRO HD (1.5).

The picture is squeezed into the frame, and the file says how wide its pixels show. Players and Premiere stretch it back. For example, HD Anamorphic 1080 writes 1440 × 1080 and shows as 1920 × 1080. This works in H.264, HEVC, every ProRes and DNxHR.

The export preview shows the picture as players will, and the Output line names both sizes, for example "1440 × 1080 (HD Anamorphic 1080 (1.333), shown as 1920 × 1080)". The preview of an 8K or other very large export is drawn smaller; the file itself is full size.

New presets

• High Quality 720p HD, High Quality 1440p 2K, High Quality DCI 4K
• YouTube 480p SD Wide, YouTube 720p HD, YouTube 1440p 2K QHD
• Vimeo 720p HD, Vimeo 2160p 4K Ultra HD
• Facebook 1080p Full HD, X (Twitter) 720p HD
• HD Anamorphic 1080 — 1440 × 1080

Save Settings as Preset… keeps a custom size and the pixel aspect too. It sits beside Import Premiere Presets… at the bottom.

ProRes and DNxHR carry the PRO badge on Creator (Pro tools and the PRO badge).
