'Wartermark Check' Function

Answered

Hello~ I am Seung-cheol Song, a salesperson of Daekyo CNS, an OEM reseller in Korea.

We are doing business in Korea under the name of VIVEex.

While I was checking the function of VIVEex, I was curious about the watermark check function.

I understand that when the recorded video is exported, it is a function to check whether the video has been forged or falsified.

I know there are three consequences when I execute this function.

‘Watermark Matched’, ‘Invalid watermark’, ‘Watermark not found’

I checked ‘Matched’ and ‘Not Found’.

But, ‘Invalid watermark’ could not be confirmed because the symptoms could not be reproduced.

To check this, I edited and checked the exported video in various ways by using video editing S/W(Animotica).

I tried to insert a part of other video, add specific effects to the video, add text boxes, and so on.

If I check the watermark of these edited videos, I'll get the results of all ‘Not found’

I want to see ‘Invalid wartermark’.

How can I see it?

Let me know how to do.

I am trying to acquire GS certification in Korea now.

GS certification is short for Good Software, which guarantees quality.

I have to show and explain the watermark function directly to the person in charge of the certification test, but I can't show and explain it.

Please tell me more about it.

  Hi @...,

  Did you reindex the archive before checking the watermark? 
  If no watermark is found, the metadata is lost and it can't be displayed and show 'Not found'. |
  If metadata is present, but the videodata is modified, the Watermark will show the 'Invalid Watermark.

  Hi, Norman Graafsma. 

  I didn't reindex the archive before checking the watermark.

  I exported a portion of the recording, and I checked the watermark with the video.

  Then, The result "the watermark matched" came out.

  After editing the exported video with a video editing program, I checked the watermark. 

  Then the result "Watermark not found" came out.

  If the exported video is edited, will the metadata be lost?

  So how can I modify videodata without losing metadata?

  Tell me how.

  Hi @...,

  I only can make assumptions, so I assume the video editing program remove the metadata which is happening with nearly all editing applications and uses its own and in that way Watermark not found is expected.
