If it were me I would put them back in the incubator and just watch them.especially if you don't have a time line and just see what happens . But still check on the pictures you can compare to get and idea what day you are in incubation.
Just go to incubating and hatching. I think if you look to the top left and see the box with three lines hit it and you should see forum's click on that and you should find it there
The 'turning black' that you're asking about, do you mean the shells on the outside? I just re-read everything after your last picture and now think that's what's got you concerned? Sorry I didn't realise that before.
It's hard for me to see much movement on your video if I'm honest, but I think if you can see it moving and the veins are good that is hopeful!
What is your humidity at?
Maybe @WVduckchick could help, or @KikisGirls, she has some experience with balut eggs
Hey thank you for responding yes the darkness on the outside of the shell has me a little concerned the one that actually is moving seems to be moving a little bit more today but yeah the discoloration of the shell has me worried the humidity level currently is at 50 but it keep going up and down I bought incubator from Amazon for about $80
