00:20 Slow motion video, how chain can jump from chainring

I hope this video can solve problem, if bike chain skipping

If you replace the chain, and the chain still skipping, jump until you lose pedal power
Please check the chainrings will most likely need to be replaced.

After 2 months, until found this problem. And the bike 11 years old.
Replace with a new chain, the chain bike is often jumping and going worse.

Wrong analize
In normal pedal, chain look good. But day by day, start going worse. Chain often skipping and more skipping
Replace a new chain, still problem and going worse. Bike Chain always jump, even medium pedal pressure will jumping / skipping
Check Jockey, not solve problem.
Check Rear Delarielleur, everything is good. Test shifting, moving gear without problems
Recheck tighten sprocket not solve the problem
Check and replace cable shifters. Problem still there
Clean shifter gear, give lubrication. Shifter more good lighter. But the problem is still there

Until we check the tooth chain ring, and source the hard sound from there.
That is the problem.
Replace the chain ring, problem solve ?

If any tooth of chainring is sharp, like a triangle pattern.
May be a problem from there.

What you must to do ! ! !
If you are never replace the bike chain, more than 5 years, and you are using your bike everyday.
Replace all new part, (1) sprocket, (2) chainring and (3) chain together.
Chain skipping like the tip of the iceberg, problem not from chain ring.
All part will effect if you already get chain ring wear.
Replace a new chain will not solve the problem.
The Chain will damage more shortly or distressed
Sprocket is a second part damage, before reach the chain ring.
If chain ring damage, sprocket definitely too.
You can check how to measurement chain, and when you must replace before get punk
