MPG vs MP4: Qual é a diferença e você deve converter?
You've got some .MPG files and you're wondering whether to convert them to .MP4 — or what the difference even is. They're both 'MPEG' video, but they come from different generations of the standard, and that gap shows up in file size, quality efficiency, and how well they play today.
The core difference
MPG (also .MPEG) usually contains MPEG-1 or MPEG-2 video — older standards from the VideoCD and DVD era. MP4 typically contains H.264 (or newer) video, a far more efficient modern codec. That means MP4 delivers similar or better visual quality at a fraction of the file size, and it plays on modern devices that increasingly stumble on older MPG files.
MPG vs MP4
MPG — older, less efficient
MPEG-1/2 video from DVDs and early camcorders. Larger files, patchy support on modern phones and apps.
MP4 — modern standard
H.264 video in a universal container. Smaller files, plays and edits everywhere.
Should you convert MPG to MP4?
If your MPG files play fine and you don't need to share or edit them, there's no urgency. But convert to MP4 if any of these apply: the files won't play on your phone or a modern app, you want to upload them somewhere, you're importing them into a current video editor, or you want to reclaim storage space — re-encoding MPEG-2 to H.264 often shrinks files significantly.
Will converting reduce quality?
Any re-encoding involves a small quality change, but MPG is already limited by an older codec, so a good MP4 conversion looks essentially the same while producing a smaller, far more compatible file. For most home videos and old clips, the trade is well worth it.
O resultado final
MPG is older MPEG video; MP4 is the modern, efficient standard. If your MPG files still play and you're not sharing or editing them, you can leave them alone — but convert to MP4 to modernise old footage, save space, and make it play and edit anywhere.
