Recently, my laptop had some problems from its charger and had shut down suddenly couple of times when the charger was getting plugged in. The charger was replaced and the problem is no longer appearing.

I've also done a sfc check since then and there are no errors appearing.

However, my question is - will any videos converted from a software that i have on my laptop be damaged in the future after these sudden shutdowns? Do I need to re-install Win7 just because of couple of shutdowns to make sure that any video file converts (from 1 format to .mp4) won't be damaged in the way or the video converter can still do the process even if some OS files were missing or corrupt?

Or does the video converting process have nothing to do with that and the integrity of the files will remain the same?

In regards to that question, it's a possibility that corrupted system files could cause a program (including whatever you're using to encode) to fail. I'd be surprised if the only clue in such a case would be errors observed in the output files though (as opposed to error messages generated by either encoding program or Windows itself, the program not loading or stopping or something). In that case a reinstall could be necessary.

The video encoder itself likely depends on Windows system files or other components which could be affected even if the program wasn't active at the time,

Of course, there are lots of small dangers PC users encounter every day, not to mention the possibility of being swallowed by a sinkhole on the way...

The immediate danger from improper shutdowns / power losses is to system files because they're the ones most likely in use at any given moment. Files not in use shouldn't be corrupted in such a way. If you were playing back a file or in the middle of an encoding job that particular video could possibly be corrupted because it's in use.

Frequent corruption of random files sitting on the drive would more likely point to problems with the drive itself.

Thank you.

I am talking not about momentary shutdown during a video conversion (this has never happened), but for future conversions only after this has already happened.

I mean if video conversion will be corrupted just because of couple of already past shutdowns that might have corrupted the OS. Do I need to re-install the OS or video-converting will be fine?

There was no way this exact program (the video converter) got damaged out of nowhere during these shutdowns, without even being turned on, right? I mean, future video conversion won't be affected in any way by these OS shutdowns? This is my main concern.

Well, I have used the video converter and there seems to be no problems with either the program, the process or the output file.

But how do I know for sure that the converted file has 100% integrity? As long as it plays from start to finish, or in random places, it should be fine, right?

That's more or less the idea. I'm not familiar with any utility made specifically to test media files in such a manner but since the point of the file is to produce a clean video then the basic test is to play it. Sometimes a player reports errors in the file (often before it plays at all) if there's a serious problem, otherwise an otherwise good file may not snap to random times and play.

Thanks!

So I shouldn't re-install my whole OS just because of that, right? I mean, it doesn't sound going through all the hassle just because a bit of a worry and no actual reasons to think so.

Thanks and final question.

Even if the video doesn't have 100% integrity, the bits that play properly (on my phone, laptop, etc) will also play during the undamaged bits, no matter how many times I play throughout these specific parts, right?

I mean, they can't get damaged by being played hundred times?

Thank you.
