In Topic: Underwater Camera Advice

30 January 2016 - 01:53 AM

Hi all,

I have been looking to put a camera on my boat so that I can see into the water on one off the lakes I go on as I would like to see the bottom at about 6ft deep, could anyone advise on a camera that would be able to see into the water in the day or night.

The camera will be fitted to the side on the boat and be powered by two 6v battery so powering it is not a problem.

I will be using a wireless transmitter and reciever back to a video screen to view it all.

Would appreciate any help you could give me.

Are you looking for something like this?

ffmpeg -y -i "input.mp4" -c:v libvpx-vp9 -pass 1 -crf 25 -b:v 0 -threads 4 -tile-columns 0 -frame-parallel 0 -auto-alt-ref 1 -lag-in-frames 25 -an -f webm /null

ffmpeg -i "input.mp4" -c:v libvpx-vp9 -pass 2 -crf 25 -b:v 0 -threads 4 -auto-alt-ref 1 -lag-in-frames 25 -c:a opus -b:a 64k -f webm "output.webm"

 

I tried the above codes successfully, but the output is just a bit smaller than the input H.264 4K file.
