Local conversion competes with other open apps for processor time during this MPG-to-MJPEG job.
High-resolution MPG footage increases conversion time and memory use.
Check picture, sound, and timing in MJPEG before removing the source.

MJPEG serves capture, inspection, and frame-based editors, whereas MPG commonly serves older Windows players and disc tools.
For MPG-to-MJPEG delivery, plan for very large output files.
After leaving MPG, the receiving app must support the streams encoded inside MJPEG, not only its extension.

MPG to MJPEG taking too long? Reduce other processor activity and leave the page open until completion.
MJPEG converted from MPG not opening? Test a compatible player and inspect the output streams.
Inspect the generated streams when an app recognizes MJPEG but refuses playback.

When does MPG to MJPEG conversion make sense?

It is useful when MPG media created for legacy playback and authoring must enter a MJPEG system designed for frame-accurate review.

Where is the MPG source processed?

The browser prepares MJPEG from MPG on this device instead of sending the source to a remote conversion server.

How can I approve MJPEG converted from MPG?

Test the MJPEG file in the receiving app and compare duration, picture, sound and timing with the MPG source.
