Video extra grainy in the beginning of the clip

[snowyjump20341]

Hi!

I want to know if my Gopro hero 7 black is faulty, please do same test on your Gopro to see if its a general issue/or non-issue.

I've noticed that all video clips are more grainy the very first second of the video clip. It is more noticable in low light. 

Do the test by increasing the iso to 6400 in low light. Record and watch the clip. The first second of the clip should be more grainy then the rest of the clip.    So from 00:00:00 to 00:00:01 is grainy and from 00:00:02 - rest of the clip, less grainy. 

What I've already done:

Manual update

Reset to factory default

Hi @snowyjump20341,

I think it's normal since it's on 6400. 

The camera has small sensor and not good for low light with high ISO. 

Thanks for letting us know. 

We'll forward that to our team if it's something can be enhanced by firmware update or it' really a hardware limitation.

Hi, thank you for your reply. Please read my question again. To clarify, the issue is visible even in day light, but it is more noticable in low light. The test is to be done in high iso in order to determine the issue. It is the very first second of the clip, not the whole clip.

Yup @snowyjump20341,

I tried as well and I have the same. 

But have you tried exposing the camera to the light first before pressing the shutter button?

I really have grainy footage in 6400 but not really noticeable in good lighting environment.

Hi again, Yes I have tried that. The problem is that only the first second of the video is extra grainy. I just want to know if I have a faulty Gopro, with defected sensor or something.

Hi @snowyjump20341,

Please try to upload a sample video.

We'll check it first.

You can upload it on dropbox or any cloud storage or YouTube and share it here.

Thanks!

I don't have dropbox, cloud storage or a youtube channel. It is easy for any owner to test it. Film in high iso in lower light. The first second of the clip should be more grainy than the rest of the clip.
