Frequently Asked Questions
Will resizing reduce my video quality?
Resizing requires re-encoding, but we use high-quality H.264 settings (CRF 23) to minimize any quality loss. The result looks excellent on all platforms.
What social media presets are available?
We offer presets for TikTok/Reels/Shorts (1080x1920), Instagram Feed (1080x1080), Twitter (1280x720), and YouTube (1920x1080).
What happens if my video doesn't match the target aspect ratio?
By default, we maintain the aspect ratio and add padding (black or white bars). You can also choose to stretch the video to fill the exact dimensions.
