android video issue and solution 3
Tested them both, they work like charm.
I guess what's left for me to tackle next should be about: (1) Micro SD card scanning/repairing, (2) find out how to avoid corrupting your files, find out why this happen and look for quick solutions.
Out of convenience, I must also create a special "label" for this topic for quick reference.

rust remover solution 2
Continuation or update from thread:

Potassium oxalate suggested in the video: chemical store price where I live turn out very expensive (PHP1,800 for 250grams); no go for me.
I found out that the oxalic acid used in laundry to whiten white shirts produce same result. And this chemical is very cheap. It'd remove rust easily. Serve also as decent degreaser. Found out also many people in youtube are using it.
This is a 428 size 42T rear sprocket with matching chain without all those rusts any longer upon closer inspection (immersed for 2-3 hours in oxalic acid):
android video issue and solution 2
This should solve file copy issue: your large-sized files getting corrupted/damaged whenever copying them from android to Micro SD card; even, moving them "all" at once to your PC, fret free 😎
The first thing I tried was the opposite route. Installing an FTP server into my PC and then a shell or terminal for the android side. I was going to command-line my way for the files to move across the LAN. BOLD 😀

There was a small hitch because I'm not yet familiar with android pathnames. You needed this small detail since the syntax I'm sure, require this for the client to talk to the server. I'm going to explore more about this solution soon; for now, our android serve as server.

android video issue and solution
Big Mistake: NEVER "move" multimedia files from Internal Storage into External Micro SD. especially for larger filesize. Use "copy". It's safer. Multimedia: video, audio, pictures.
Selecting "all files" and then "move" them to your Micro SD, something bad's bound to happen unless there's this dude by the name of Virgil, who was sent from power divine to protect us from kind of shit that you don't want right now in your life. Meaning: we can do all-reckless stuff and yet, still get away without breaking anything, because supremest wisdom and primeval love. Say No More! 😆
By the way, the chances of the Micro SD card being problematic-defective are also there creating all the file damage. I'll research for softwares that'd detect and or fix should be this the case. Maybe you can scan/fix, just like harddisks when they had bad sector, IDK.
Nevertheless, for poor souls like me, the dude that none of us really want by the name of Murphy take the place of Virgil to summon all the clusterfuck in the world. Need to be extra careful since power divine had all hope abandon, every step of the way must be verified to make our day uneventful. If necessary, I'd painstakingly copy file-by-file avoiding long hours of trying to salvage what was already irreversibly damaged by what simple "copy" command could fix. All-those precious backup files, imagine them waving goodbye 😆
Not sure whether the newer androids or newer Micro SD cards still be having those issues provided they already operate faster clock speed, but mine def still old models so the dreadful scenario over files wind up corrupted and bad-case destroyed i.e. impossible to recover, easily became case of shit bricks and world of hurt 😅
Again: don't "move" files because you're in a hurry. Copy -take the long route- those files first to the external storage, so you still have them original files should things start going wrong.
Verify on your PC for "The entire file is filled by 00 byte!" error --using "recover_mp4" program, before deleting those originals. Usually, the tell-tale sign of corrupted video, audio, or photo files are those icons not showing the content of the file like its thumbnail preview.
Notepad can also tell you straight up -if the video files that you copied were already beyond repair. Video file will be blank in notepad. If not blank, then the procedure below will be able to help you. If blank, no ASCII or anything, move on, they are no longer with us -learn from your mistake.
Below is a good instruction video how to recover video provided it was not the 00byte case:
