Keep landscape and portrait proportions
Introduction

Preview editorial example: copy and imagery will be reviewed before launch.
Understand 16:9 and 9:16 output dimensions without stretching or cropping.
Review your source
The preview supports 16:9 and 9:16. Landscape 1080p is 1920 × 1080; portrait is 1080 × 1920. Check the source aspect ratio before choosing a resolution for the intended screen.
Prepare a supported clip
The preview accepts MP4 / MOV with H.264, 8-bit SDR, and AAC or no audio. Use 16:9 or 9:16 clips up to 60 seconds, 200 MB, and 30 fps. Input edges must not exceed 1920 by 1080.
Choose an output and review the quote
After upload validation, choose 1080p or 4K larger than the source. Review the dimensions and credit quote. AI processing starts only when you confirm; uploading and previewing alone do not consume processing credits.
Compare and save the result
Once complete, switch between the original and output to review still detail and movement. Download the MP4 promptly: originals remain accessible for 24 hours and results for 7 days. This is not long-term video storage.
