Change Resolution

Resize intelligently without losing clarity. Keep aspect ratios intact and export web‑ready videos.

How it works

Open a file, set Resolution to Preset or Custom, and choose your target size. The converter uses high‑quality scalers and preserves aspect ratio by default. For vertical outputs select 1080×1920, and enable Max compatibility to force yuv420p when broad playback support is required.

You can lock framerate to 30/60 fps independently and keep audio parameters on Original to avoid unnecessary re‑encoding.

Resolution Q&A

Should I keep the original resolution?

In most cases yes, especially when you will edit again or display on large screens. Downscale only if you need smaller files or faster delivery.

Best presets for web playback?

Use 1920×1080 (Full HD) for YouTube/Vimeo on desktop, and 1280×720 when bandwidth is limited. For vertical platforms pick 1080×1920.

Does bitrate change with resolution?

Yes. Lower resolutions require less bitrate for the same perceived quality. If you switch from 1080p to 720p, you can typically reduce bitrate by ~30–40%.

How do I avoid black bars (letterbox/pillarbox)?

Keep the original aspect ratio. If you must force a different ratio (e.g., 16:9 → 1:1), crop before scaling. Avoid stretching.

Which scaler is used?

FFmpeg’s high‑quality scalers are used under the hood (e.g., bicubic/lanczos). The app chooses safe defaults so edges stay crisp without ringing.

Upscaling 720p to 1080p — is it worth it?

Usually no: you won’t gain real detail. Upscale only if a platform requires a minimum resolution or to match an existing project timeline.

What about framerate when changing resolution?

Resolution and framerate are independent. Keep Original framerate when possible. Lock to 30 fps for general content or 60 fps for sports/gaming.

Vertical videos for TikTok/Shorts?

Choose the preset 1080×1920. If your source is horizontal, consider cropping the center instead of stretching.

Can I convert 4K to 1080p safely?

Yes. Downscaling from 4K to 1080p preserves sharpness on laptops/phones and cuts file size dramatically — ideal for distribution.

PowerPoint/old TV compatibility?

Stick to MP4 (H.264), yuv420p, and conventional resolutions (720p/1080p). Avoid odd widths like 853 px.
