Not the bullet. Sorry.
When the gun fires, first you get ignition followed by the bullet leaving the barrel very quickly. That is then followed by the muzzle flash. With muzzle flash is when the shooter really is impacted as the action starts to cycle and the recoil/muzzle rise occurs.
Muzzle flash, recoil, and the cycled slide have all been mentioned. Something is terribly wrong if the bullet has only traveled that far by the time the muzzle flash has completely gone away, the gun is in mid cycle, and well into recoil. Where is the spent case? It may be out of the frame, but you get the idea.
Why is the supposed bullet so bright when the flash seems to have trouble reaching down range?
If that is an object from the gun, then likely it is something like a glowing powder fleck. Note that there is a second small but illuminated object that is directly down range from the muzzle in the current position. Is that another bullet? Nope. It is just more crap in the air, ejecta from the cartridge, most likely.
You can catch projectiles in the air, but it would not be likely to do so in low light using a puny flash, and to get a perfectly still-looking frozen projectile shot like that.
Indoor shooting environments are full of airborne particulates, ejecta from the discharged rounds. Thing may drift in and out of camera/flash range without you ever being aware of it.
