Compare input and output bytes and play the whole export. Small already compressed clips can get larger; use your real file to judge savings.
Use MP4 Compressor when the source is already MP4
If the source file is already MP4 and the only job is to make it smaller, MP4 Compressor is the cleaner route.
Use Video Compressor when the source can vary
If the source might be MOV, WEBM, MKV, or another video type, Video Compressor is the broader starting point.
Compression is for size, not for format rescue
If the real problem is compatibility rather than size, a conversion route is usually the better first step.
Compression is the stronger choice when the file already plays and the only pain is weight.
The shortest decision rule
Already MP4 means MP4 Compressor. Mixed or unknown video input means Video Compressor.
