Smart Aspect Normalization

Cloud-Powered FFmpeg Concatenation Engine

Combining media files with mismatched frame rates, aspect ratios, or audio sampling rates usually causes playback stutter or crashes simple video editors. AllMediaSave solves this with conditional FFmpeg normalization.

Our service probes the primary video track to establish target dimensions (such as 1080x1920 portrait or 1920x1080 landscape). It scales and pads subsequent clips with letterboxing to prevent stretching, harmonizes audio to 44.1kHz stereo, and concatenates all segments into a single, seamless MP4 or MP3 file.

Frequently Asked Questions

Clear answers to common questions about downloads, formats, and privacy.

How many files can I merge at once?

You can combine between 2 and 6 tracks per merge job.

What happens if I combine a 9:16 vertical video with a 16:9 horizontal video?

Our FFmpeg engine takes the aspect ratio of the first video and applies smart letterbox padding to the second video, ensuring neither is stretched or distorted.

Is there a file upload size limit?

We support uploads up to 500 MB total per merge job.
