Importing GPS coords from 360°.mp4 to rendered frames in 360° .png

[david.matousu]

Hello everyone, there is my problem:
I have source 360° .mp4 file (captured with Insta360 Pro, with GPS metadata), which I need to edit in After Effects - some retouching etc. and then export it as .png sequence. But after export, I lost this metadata...
Is there some possibility how to embed gps coords to the relevant .png frames?

I exported the data using exiftools

Code Select Expand

exiftool -ee -p gpx.fmt F:\source.mp4 > source.gpx

Can I write this somehow in bulk to the png frames? Or I have to do it manualy to each frame?

This is only test sequence, about 30 seconds long. But the final video will be about 1 hour long, so I would appreciate some "automatic" procedure

Thank you very much

If you could figure out how to get the correct timestamp for each of the frames, then it would simply be geotagging the images.

Hi thanks.
Do you have any idea how to do this? I've tried some things from the link you sent, but I don't understand it very much: /

Thank you,
David

Hi David,

First, set DateTimeOriginal for all the frames to be the same as the video:

exiftool -tagsfromfile VIDEO.mp4 "-datetimeoriginal<createdate" -ext jpg DIR

Then increment the times of each video based on the time separation between the frames.  See this thread.

Then do the geotagging of the jpg files from your .gpx output:

exiftool -geotag source.gpx -ext jpg DIR

Thanks, its working

I have one question: it is possible to adjust the time to less than a second? I tried something like:

Code Select Expand

"-datetimeoriginal+<0:0:0:${filesequence;$_*=1}"
or

Code Select Expand

"-datetimeoriginal+<0:0:${filesequence;$_*=0,1}"

In the gpx file is time  2021-02-12T14:21:11.7Z - can i somehow match these nanoseconds or it doesnt matter? We are going to make some sort of virtual tour from the car and we need picture every 5meters (for example)

Thanks

I have one question: it is possible to adjust the time to less than a second? I tried something like:

Part of the problem is the fact that the EXIF timestamps such as DateTimeOriginal only hold full seconds.  Subseconds are held in a different tag, SubSecTimeOriginal.  So in order to shift the time, it would have to add to the SubSecTimeOriginal and then carry over into the DateTimeOriginal.  And exiftool doesn't have that ability as far as I know.

But I think I figured out a way using the XMP timestamps.  You could try using XMP:DateTimeOriginal
"-XMP:DateTimeOriginal+<0:0:${filesequence;$_*=0.1}"
(note that you have to use a dot, not a comma to separate the decimals)

Example

Code Select Expand

C:\>exiftool -g1 -a -s -XMP:DateTimeOriginal y:\!temp\Test3.jpg  y:\!temp\Test4.jpg
======== y:/!temp/Test3.jpg
---- XMP-exif ----
DateTimeOriginal                : 2021:03:01 08:48:12.99
======== y:/!temp/Test4.jpg
---- XMP-exif ----
DateTimeOriginal                : 2021:03:01 08:48:12.99
    2 image files read

C:\>exiftool -P -overwrite_original "-xmp:DateTimeOriginal+<0:0:${filesequence;$_*=0.1}" y:\!temp\Test3.jpg  y:\!temp\Test4.jpg
    1 image files updated
    1 image files unchanged

C:\>exiftool -g1 -a -s -XMP:DateTimeOriginal y:\!temp\Test3.jpg  y:\!temp\Test4.jpg
======== y:/!temp/Test3.jpg
---- XMP-exif ----
DateTimeOriginal                : 2021:03:01 08:48:12.99
======== y:/!temp/Test4.jpg
---- XMP-exif ----
DateTimeOriginal                : 2021:03:01 08:48:13.09
    2 image files read

I think you'll need to use the GeoTime tag to make sure you use the correct timestamp, but I could be wrong
"-Geotime<XMP:DateTimeOriginal#"

Correct.

Smart.

"-Geotime<XMP:DateTimeOriginal#"

Correct.
