Aspect Ratio
The proportional relationship between a video's width and height, such as 16:9 (widescreen) or 9:16 (vertical).
Aspect ratio is the proportional relationship between a video's width and height. It determines the shape of the video frame and significantly impacts how content is consumed across different platforms and devices. Common aspect ratios include: 16:9 (standard widescreen — YouTube, websites), 9:16 (vertical — TikTok, Instagram Stories, Reels), 1:1 (square — Instagram feed, LinkedIn), and 4:3 (traditional TV format, rarely used today).
For testimonial videos, aspect ratio choice depends on the primary distribution channel. Website embeds and YouTube favor 16:9 widescreen. Social media repurposing requires 9:16 vertical or 1:1 square. The most versatile approach is to record in 16:9 (the default for most cameras) and crop or reframe for other platforms in post-production.
Aspect ratio has a meaningful impact on how testimonials feel to viewers. Widescreen (16:9) feels professional and cinematic. Vertical (9:16) feels personal and mobile-native — it fills the entire phone screen, creating an immersive experience. Square (1:1) is a compromise that works adequately everywhere but optimally nowhere.
Modern testimonial platforms increasingly support multiple aspect ratios — recording in one format and automatically generating crops for other platforms. When repurposing testimonials across channels, pay attention to framing. A talking head video framed for 16:9 with the speaker centered will crop well to 9:16, but a speaker positioned off-center may be partially cut off. Guide customers to center themselves in the frame for maximum repurposing flexibility.
Frequently Asked Questions
What aspect ratio should I use for testimonial videos?
Record in 16:9 widescreen — it's the standard for websites and YouTube. If you plan to repurpose on social media, record wide enough to crop to 9:16 vertical later, or ask customers to center themselves in the frame. Many testimonial platforms now automatically generate multiple aspect ratio versions from a single recording.
Can I convert a 16:9 testimonial to vertical 9:16?
Yes, through cropping — but you'll lose the left and right sides of the frame. This works well for centered talking head videos but can cut off important visual elements on the sides. Some editing tools offer 'auto-reframe' features that use AI to track the speaker's face and keep them centered in the vertical crop.
