Two clips can both be described as 1080p while having very different file sizes. Resolution does not specify all the data in a video. Neither the 1080p label nor the number of megabytes is sufficient to choose a delivery file.
Resolution is only one variable
MDN explains that codec and quality settings affect size and retained detail. Higher bitrates mean more data per unit of time, so comparisons at equal duration generally produce larger files at higher bitrates.
Check duration too. Longer clips contain more material, but duration alone cannot predict size across different encoding settings. Audio and other file data also contribute.
Compare what the recipient needs
We recommend recording these observations before choosing between copies:
| Comparison | Useful question |
|---|---|
| Duration | Are both the same section and length? |
| Image dimensions | Have you checked actual width and height? |
| Picture and sound | Is text readable and speech complete? |
| File size | Does this actual file meet the destination's requirements? |
For different content, a size difference is not evidence of a converter fault. A larger file also does not prove that source detail has improved.
Choose trimming or compression
If some material is unnecessary, use Trim video first and inspect speech at both boundaries. If the full clip is needed, try Compress video starting from the original.
FileMyLove offers light, balanced and strong levels with different quality and image-size settings. It has no custom video bitrate or target-MB field. The light level's 1080 value caps the shorter image side; it does not make every file the same size. See compression levels for readable text for the individual settings.
Check the actual result
After downloading, compare duration, size, important scenes and audio. Test playback in the recipient's application. If compression does not produce a smaller file, the site reports that outcome; no fixed reduction percentage is guaranteed.
Converting to MP4 alone is not necessarily a compression command. Mediabunny distinguishes changing the container while copying media data from re-encoding. Retain the original and choose the operation for the problem you need to solve, rather than repeatedly processing copies without checking them.
