How to convert MPG to MP4
Choose your recording
Open a .mpg or .mpeg video directly. Uppercase file extensions work too.
Choose a resolution
Start with Original for a standard-definition recording. The video is re-encoded as H.264 even at its original size.
Download the MP4
Select Convert, then play the result to check the picture and sound. Download it before closing this tab.
Which file should I use to convert MPG to MP4?
Choose the recording that plays on its own
Select a .mpg or .mpeg video from your device. A shortcut, a disc menu or an editing project can open a recording in another application without containing the footage itself. Open the video directly in a media player and seek near its end. If the music or narration is audible only inside the editing project, export a video that includes that mix before you convert the MPG to MP4.
Distinguish the original capture from a viewing copy
When two files have the same opening frame, compare their durations first. A shortened export can look identical in the thumbnail but leave out part of the recording. Next check the frame dimensions and look at a fine detail such as a date stamp. If you have both the capture and a smaller copy, start with the capture. Enlarging a small copy cannot recover lettering that has already become unreadable.
What to do if the MPG preview stays black
A blank preview can mean that the browser cannot play the original MPEG video. Try the same file in a local player. If it plays there, you can still try converting the MPG to MP4 and check the exported picture in this tab. If both players stop at the same point, compare the file size and duration with another copy of the source before changing the output resolution.
Which resolution should I use when converting MPG to MP4?
Keep the detail in a tape or TV recording
For a 720 × 576 capture, Original retains all 576 lines. That matters for small details such as dates in the corner of home videos or names in TV credits.
Make a smaller viewing copy
Choosing 480p for a 576-line source reduces its height by 96 lines. Try this for a phone copy, then check any on-screen text at the size you expect to watch it.
Keeping a widescreen MPG in proportion
A 720 × 576 recording can display as 4:3 or 16:9. The frames show both shapes at the same height. Our MPEG-2 sample used 16:9, and its MP4 kept that shape with Original selected.
What happens to the picture and sound during conversion?
Frame dimensions and display shape
A player uses the recording’s display information to decide how wide the image should look. The width and height listed in the file properties alone may not tell you whether an older TV capture should fill a widescreen display. When you convert MPG to MP4, compare the same frame in both files with stretching and zoom switched off. Black bars that are already part of the picture will remain in the copy.
Horizontal lines around moving objects
Pause on a moving hand or the edge of a moving vehicle. If its outline breaks into alternating horizontal lines while a stationary object stays sharp, the source may be interlaced. Look at the same frame in the MPG. This page lets you set the frame height but has no control for field order or deinterlacing. For a progressive export, handle the fields in an editor before making the MP4.
Keeping the download within a size limit
A height such as 480p describes the picture, not the number of bytes in the download. File size depends on the running time and the combined data rate of the video and audio. One minute at a total of 2 megabits per second is about 15 MB before container overhead. After converting the MPG to MP4, check the size of the saved file against the actual limit. Use the compressor if you need a particular size.
How to check the converted MP4
Check the picture shape
Play the same scene in the original and the MP4. A clock face or a wheel viewed straight on makes stretching easy to spot. Set the player to the video’s own aspect ratio before comparing.
Check the sound at both ends
Find a visible cue such as a clap or a speaker’s lips near the start, then repeat near the end. If the sound drifts, check those same moments in the MPG to see where the offset begins.
MPG conversion questions
Can I convert MPG to MP4 if the recording won’t preview?
Yes, if the conversion engine can read the recording. Our MPEG-2 sample above would not preview in Chromium, but its exported MP4 played with both picture and sound.
Why is the MP4 larger than the MPG?
Frame size and file size measure different things. Our two-second sample went from 530 KB to 910 KB at the same resolution. If you need to meet an upload limit, use the video compressor after conversion.
Will the MP4 include my soundtrack?
Readable audio in the selected recording is converted to AAC. If the music plays only inside your editing project, export the video with that soundtrack first.
Why do moving edges show horizontal lines?
Old TV and tape captures can contain interlaced video. Changing the resolution keeps this combing. For a progressive copy, deinterlace the original in an editor before converting.
Can I convert a recording from a link?
Choose the URL option and paste a direct HTTPS link to the media file. If the link opens a watch page or the host blocks the import, download the recording and choose it from your device.
