For a bootloader, that's true. I was also using the programmer to program a blink sketch into it for testing purposes, and that did require a crystal to run after programming.
I know that's what the Adafruit link says, but the atmega328_optiboot example was wired differently and i was following that.
Chuckle. Always read the source, I say. I'm not entirely sure why the example uses the pin both as an input to start programming, then as an output to control the programmed ICs reset line. As this was just a "let's build it and see" project, I trusted that the author had a good reason for doing so and didn't dig into it.
The green LED comes on as soon as programming begins. The red LED only comes on if there's an error.
With no IC to be programmed, the green LED comes on to indicate that programming has begun, and the RED led comes on virtually simultaneously. That's what the example did and I left it as it was.
Assume the Piezo beeped ?
The piezo only beeps on successful programming.
I had higher resistor values on the LEDs but that's irrelevant. Other then the crystal and supporting caps, and a 0.1uF on Aref (all on the target), that looks like it matches what I put together.
However it seems in the video they use a DIP package as a controller. I suspect it is an Arduino preprogramed to program the controller in the ZIF socket.
Hello, which sketch I need to upload in the left side controller to work as a bootload burner?
Can I burn bootloader into these chips? Atmega8/168/328??
It would be great if you provide steps.
See also Optiloader, which turns an Arduino into such a stand-alone programmer.
(The project you linked seems to be just a custom layout of an Arduino.) A cheap Nano will do fine.
There are of course many "alternative PCB layouts" for an Arduino. Here's one that has a ZIF could be turned into a programmer relatively trivially, by putting optiloader into a chip that would go on the SMT layout and connecting a few wires...
Both Adafruit and Nick Gammon have expanded on the optiloader idea, but they both also use a standard Arduino (or mega) as the "active" compute power.
Yes but which program I should burn in the master controller to make the same?
It would be great if you would actually read the information you have been previously provided with and see that your question has already been answered.

This is what I am looking for at post#39. I know that Larry can provide proper information with details.
Thanks @LarryD Inwill try and let you know.
Great. Will try and let you know. BTW can we convert this schematic to PCB layout?
Who are we ? 
You can use one of the many PCB programs to design PCB boards.
EasyEDA, KiCAD and others.
