When this route helps
Useful when an archive or legacy Windows file will not play where you need it. Keep the AVI as the source until the full MP4 has been checked.
AVI describes a container, not one codec
AVI files can contain many video and audio formats. A simple fixture may convert cleanly while an unusual codec, damaged index, variable timing, or multiple streams needs closer review.
Questions about this conversion
Will every AVI file convert the same way?
No. AVI can contain different codecs and stream layouts. Test playback, duration, audio, seeking, and important frames in the finished MP4.
Does LocalFlux upload the source file?
No. Normal supported conversion runs on your Windows PC without a file-upload step or account.
Will LocalFlux overwrite the original?
No. LocalFlux writes a new output copy and leaves the source file unchanged.
