70mai pro plus dashcam gps,speed extraction, logo removal

[tankhiwale]

Hi,

I am trying to extract gps and speed information captured with 70mai pro plus dashcam(sample linked below). however unable to do so with-

exiftool -ee -G3 <FILE>

~> exiftool -ver
12.15


Video from dashcam is here - https://drive.google.com/drive/folders/10ESU6ca_C_N0DBbvo6OjFlrLsULqYOgE?usp=sharing

ffprobe also does not reveal any suggested gps metadata embeded in the video. However the video when played shows the information. Apologies if I am missing something, begineer here.

Additional stuff I am trying is to remove the 70mai logo embedded in the video.

It'll be up to Phil to determine if there's any gps data embedded in the file, but presence of the gps locations on the video does not mean that the data will be embedded in the file.  What you see on the video is burned-in the video.  It's not like subtitles which you can turn on and off.  The same goes for the logo, it's permanently part of the video.  It's not metadata that can be edited to remove it.

I have other 70mai samples that do contain timed GPS metadata, but this one does not.  The GPS in the video is part of the video image, not metadata.

Many thanks for your responses .!  I'll now try OCR to extract that information and probably crop the video.
