How to import .blend file?

Hello, I edited a .mp4 file. I tried to export as a .mp4 file, but a .blend file was created.
So, I Opened the .blend file in Blender Video Editing, but there’s no tracks in the Sequence Editor.
Any suggestions please?

You need to export by using the Render button

You don’t add blend files to the sequencer

Any suggestions please?
Explain clearly what you are doing, what you want and what the problem is with clear examples

Also use the appropriate support forums for support question instead of posting in the first forum you see. Thread moved

Hello, I fixed this by recopying the original video file as a .avi file and then using the Render output options.
