COULD video formats contain any GPS information?

[kenny1999]

when I take pictures with my iPad and transfer the pictures to my computer , it could contain GPS coordinates sometimes, which is a privacy concern. I'd like to know video formats would contain any GPS or EXIF information. Where to check?

MediaInfo

Sure, video streams&co could contain additional meta data as:
a. additional streams with coordinates could be added (like a subtitle stream)
b. some global data could be put inside tags
c. custom headers could be added
d. info could be embedded inside the video (through digital watermarking)
different container and video formats have different options for tagging and custom stream infos,...
=> you might want to read up on the container and video format you use to know more of the possibilities
(tools like MediaInfo&Co will only help in some cases, since they normally only show a few selected header infos)

It probably all depends on the programs that are used to create the streams.
Seeing that there isn't always a way to detect for example digital watermarking (in audio&video) for copy protection there are probably tons of ways to add such meta info without the users knowledge.

Take a look in the iTunes store.
I saw several programs that claimed to extract EXIF data from photos and videos.

I m using PC, not Mac

I read that the videos were from a iPad, sorry. Thought you had a Mac.
But assuming Apple users have software that might read the data, there should be a MS program that could do similar.

I don't have a Mac. I have an iPad. Can I still strip off all the EXIF-like data on videos

You're going to have to be very specific. Selur laid out the different ways the information could be contained in post#3.

So what is the actual source of your files? What kind of files are they -- codec and container?

You've mentioned you have a PC and an iPad. You're likely to have better luck finding apprpriate software for the PC than the iPad.

There is no one-size-fits-all solution. (The most reliable solution of course is to turn off the GPS tracking in whatever camera or device you're shooting with.)

If I understood all correctly, we are talking about GPS metadata of jpg and mov files which are stored in the files. An iPad uses H.264 and AAC. Does that info help to delete the gps metadata? I don't think so.
We need a software which deletes the gps info of the files.

For future files: There is an option to turn off gps metadata writing.

All the videos were taken by iPad mini 2 WiFi only version which are imported into PC running on windows 10

GPS is not stored in one big "EXIF-like" header. Instead, GPS video info is stored with each frame. This lets you identify where you were as you walk, ride, or fly around (in case of my drone). My Sony camcorders let me use some Sony software that will actually give me speed readings from video taken while driving down the road, as one example.

So, you can't just delete one little set of data at the beginning of the file. Instead, you'd have to look for software that can demux GPS data in the same way that some software can demux audio tracks. I just did a quick Google search to see if such a thing exists, but I didn't find anything.

you could try DEMUXing and reMUXing into a new video with ffmpeg and see through comparison if the GPS info is still in there. I suspect that ffmpeg will not include it, but it won't hurt to at least try it.

note, if you already know any GPS data pieces, i.e., like city or state, then you can do a binary search for such key works, ie, "NY" or "New York", etc. If you find it in video_A but not in video_B, then you have your solution.
