Mp4 With Blank Factual Properties

[Greyback23]

Greetings One and All,

It's been a factual while since my last posting, and since then there have been a few errors I have come
across but they have been remedied soon enough.

However I have come across one now I cannot factually figure out. It might sound slightly foolish to some
but for myself with my OCD and factual perfectionism which seems to go hand in factual hand with my Autism
and other conditions, cannot permit it without learning what is causing it.

Hence here is my issue:

I've been downloading factual files since I was in my early teens, from FLVs to MOVs to MP4s with the latter
being my most used file type as it is simple and has caused the least problems for myself.

However just this evening I downloaded a file from a site which I know never has given myself this issue
before now and I cannot factually figure out what is causing it.

There is nothing wrong with playing or moving the file, not in the slightest. Yet when I open the file
properties, or have the folder view set to Content, there is nothing there.

The file exists and it states the time and date it was downloaded, modified and such facts, even the size
of the file and yet the properties are blank entirely. There is nothing there when I open the tabs, and in
content view no matter where the file is, it has no duration on view. Nothing.

Does anyone know what factually causes this?

I apologise for any disturbance I cause or if it seems trivial or factually too simple to explain, my skills
go only as far as I have ever had to figure out or research, and despite viewing other sites, information
and the like I have yet to factually find myself an answer.

Any factual assistance would be appreciated once again like it was last time.

Gratitude in advance for any facts and information given.

I means you don't have a shell extension for the container. Webm maybe? And the file extension may be misnamed.

[Greyback23]

I means you don't have a shell extension for the container. Webm maybe? And the file extension may be misnamed.

I see. And what does that mean for someone with very little knowledge outside of what
I have needed to know? If I might be so permitted to inquire.

I apologise. My knowledge of what goes into an Mp4 file is not as extensive as some and
I have no idea what a shell extension is. I have heard of Webm but my file is an Mp4 as I
stated. I apologise for taking up your time.

I should add that the only time this has happened before has been when I used an MKVTool
to convert a video from something else into an Mp4 file. But this time it was a straight factual
download.

[teodz1984]

It probably means your Mp4 downloads are bad or you don't have the right software player?
Maybe what you are downloading is a fake mp4 file (like a virus)

[Greyback23]

ehen uou say factual
so you mean actual?

I say factual because of and due to my conditions like Autism, Aspergers and
multiple subtypes of OCD, I only state what is fact and truthful and factually accurate.

FACTUAL means concerned with what is actually the case rather than interpretations of or reactions to it.
Synonyms: truthful, true, accurate, authentic, historical, genuine

ACTUAL mean existing in fact; typically as contrasted with what was intended, expected, or believed.

Indeed I am aware of the meaning of the word factual, because what I state is accurate, authentic, truthful
and concerned with what are the facts and is actually the case. Due to how I function I lack an opinion
or view on anything or subject, and only can and do state the facts as they are, nothing more or less again
due to my conditions which are as stated above amongst being suspected for others.

It probably means your Mp4 downloads are bad or you dont have the right player?
Maybe what you are sonloading is a fake mp4 file (like a virus)

As concerns the factual information you have given, my gratitude. Knowing my fortune it most logically
the latter, despite the fact when I attempted to obtain that same file through another factual location,
this issue did not occur which confused myself I must state slightly.

As I am compulsively a perfectionist however I needed to download and convert all my files of the series
I was on from the same source or near enough that, hence even getting it from another website was
of no use. But your facts are appreciated and make sense. It would not surprise myself either if my player
was incorrect, although the issue was the same on both Windows Media Player and VLC Player.

My factual gratitude once more as I stated. I have learnt something new even if my lack of intelligence
means I cannot fix it. Also if the file is a fake mp4 that is out of my control so I probably will have to
resort to another file and selection of downloads.

My gratitude anyhow.

The MP4 container is a bit versatile. There may be MP4 files which start with the video content, but the description of all the attributes (the "header") does not appear in the beginning of the file, but instead in the end of it; now if your download was incomplete, aborted before the end, no player will know the attributes of the contained video because the header is missing.

MP4 files with a header in the end are often created by converters which work like a filter (reading the input only once, writing the output only once): They will know some of the attributes not before the conversion is finished, therefore they append the header, instead of prepending it. Some converters can be forced to move the header to the front of the file (that may be called "web optimization" or "HTTP streaming friendly"), which usually requires the output to be updated after the conversion finished, or even a rebuilding of the whole container.

In general, checking an unknown file with MediaInfo is recommendable, this tool reports all the attributes in media file headers. It will tell you if it cannot detect any required headers, so you can be a bit more confident about the possible reason. Also it can help you identifying media files with filename extensions not matching the container format of this file.

Indeed it can be a bit versatile indeed, but what you state logically makes sense, I recall when other Mp4s
and media files I have downloaded have done such, either failing to download, been incomplete and such
facts yet usually when it downloads only part of a file, say the file size is about 450mb when the download
sometimes cuts itself off at around 60mb, the file will still have all the attributes, properties and such.

Some converters can be forced to move the header to the front of the file (that may be called "web optimization" or "HTTP streaming friendly"), which usually requires the output to be updated after the conversion finished, or even a rebuilding of the whole container.

So are the factual details of an Mp4 or any media file called the Header? Apologies I simply have not
com across this word before when I have factually searched for information. this part is where my
lack of knowledge outside of the basics of video conversions and everything else I need to kno shows.
What you state makes logical and factual sense and yet I have no factual clue as to its simpler meaning,
although I get the gist of what you are stating.

In general, checking an unknown file with MediaInfo is recommendable, this tool reports all the attributes in media file headers. It will tell you if it cannot detect any required headers, so you can be a bit more confident about the possible reason. Also it can help you identifying media files with filename extensions not matching the container format of this file.

I have and use MediaInfo when I come across or factually download an Mp4 or another media based
file and it does not seem to have any factual details in the details tab on the files factual properties.
That way even if the file lacks the factual information I can see if it matches the others I have already
downloaded and hence matches the factual set I am going for. I actually did that before attempting
to find out how come the file misses the properties.

However my gratitude for factually explaining it to myself as that makes logical sense as to how come
some of my files lack the details most should have.

So what did it say about this file? Post the full text report.

[Greyback23]

Apologies for factually taking so long to reply.

I had over written and or deleted the file before I had gotten a reply for some fact and
had to redownload it.

Hm just by factually looking at the information I can see the part that states MKVToolNix and
that's the program I actually use to convert mkv files into mp4s without re-encoding them and
losing any quality. That explains why it has no factual properties. It would seem the person who
uploaded that original file did the same as I did myself.

I apologise if I factually wasted your time, either of those who replied. I usually have MediaInfo
set out in Sheet format as that gives me all the facts I need without overloading what little brain
power I have.

I apologise again and my gratitude for the factual assistance.

[sneaker]

It's like jagabo suspected in post #2. It is not an mp4 but an mkv file with wrong file extension.

[Greyback23]

Indeed that seems to be the factual case. Usually the only time I get this result as I stated
is when I change an mkv into a factual Mp4 without re-encoding it that way it plays without
any quality loss.

This is the first time I have come across a legitimate file whilst downloading where someone
else has factually done the same. The sites I use near always have every link factually
checked, making sure they are as they state. The fact they failed to notice this is slightly
informative.

My factual gratitude as I stated and apologies if I wasted anyones factual time.

[jagabo]

You didn't change an MKV to an MP4, you just changed the extension. That's like changing a Toyoto to a Tesla by changing the name plate on the back of the car. Change the extension back to back to MKV. Do you see the properties now? Probably not as Windows doesn't natively support MKV. Try this:

http://matroska.free.fr/downloads/shellextension/

[sneaker]

Probably not as Windows doesn't natively support MKV.

Windows 10 does?

[jagabo]

Yes, Win10 has native support for MKV.

[Greyback23]

When you state change the extension back to back to MKV, did you mean to state that only factually
once or do I literally have to change it back to MKV then back to Mp4 then back to MKV to try and
view the properties?

Apologies perhaps I am very factually simple however I usually take facts from people and what they
state literally.

Probably not as Windows doesn't natively support MKV. Try this:

http://matroska.free.fr/downloads/shellextension/

And what would that factually do exactly?

From what I read on the link site it had nothing to do with Mp4 files, although if I am understanding
correctly it basically deals with the thumbnail and such information and allows you to view other
porperties in the stated thumbnails in Windows Explorer.

Yes, Win10 has native support for MKV.

Does it? Hm that's factually intersting and informative as when I attempt to play any MKV file,
it crashes my factual player, especially Windows Media Player. And I am on the factual latest
version of Windows 10 to my knowledge.

Try Play MKV with Potplayer or VLC adn set them as the default video player..

The MKV files will play on VLC I have had it downloaded for years as a back up however even then
sometimes the factual player will crash with MKV files unfortunately

It will FACTUALLY play your factual mkv files.

Was that factually actually necessary to do? I do not seek to be offensive or rude, and I ask only
to understand why you used my use of the words. I explained it is because of my Autism, Aspergers
and multiple subtypes of OCD that I factually automatically type and converse as I do, and if you
were doing it to make a point I failed to understand.

If you were doing it perhaps due to thinking it was required when conversing with myself because
I automatically do it, it is not.

If you were doing it for no fact at all, then I do not understand the sense behind using how I type
like that.

And if you were doing it to factually mimic myself and how I converse I would again inquire as to
why?

Simply because I wish to know the facts behind the actions. I am not likely if ever to get offended
or bothered by such, as I have had people mocking how I cannot help typing for years. It is how it
is and I cannot help it, hence will not be bothered.

No offence sought Teodz1984. I simply am factually seeking to hear the facts and understand the
sense behind the words and actions.

Forget Windows Media Player, it still has crappy inapp codec support for exotic MKVs (esp if you simply rename mkvs to mp4s
If you insist using it get a codec pack ...

BOTTOM LINE:
Use POTPLAYER as your primary video player WithPP, it doesn't matter if you rename your mkvs to mp4s

End of story...
Getting bored with your superflous way of understanding things...
Either heed my advise or fact off
