You get an A+ for supplying the video but an F for not supplying the model year and engine type/size. Can't say much without them. Was any maintenance done just prior to the starting problems?

Its a 1995 Toyota Camry 1mz-fe.
The problem just started randomly. Also it still has the original Denso starter. I removed the starter and took it to autozone to get tested. It passed. I'm thinking about just replacing the starter since idk what else it could be. But idk if my problem looks like it's caused by a starter going bad. I am seriously stumpted right now.

Am I missing something? It appears the car is starting a little hard but, it is starting, meaning I can hear the starter rotating the engine, I can hear the engine start (barely) and I can see the rpms increase and stabilize at around 800 rpm. Your starter is fine. Leave it alone.
If it seems like it starts harder the longer it sits, I would suspect you may have a fuel leak, bad pressure regulator or weak fuel pump. Connect a fuel pressure gauge and check pressure when running and at intervals after shutdown. No gauge? Find the fuel test port on the fuel rail and press the inner plunger. Fuel should squirt out under pressure and not just dribble out. Do this on a cold engine before the first start of the day.
If you have a distributor you can check the timing setting using a timing light. The timing belt may have slipped throwing the timing out to lunch. Hard starting and lack of power are signs of a slipped belt.
You say you checked the spark plugs. Did you check the gap setting? They tend to open up with wear. Might be best to just change the plugs and plug wires if they've been in there more than 50K miles. Make sure the distributor cap (if equipped) and rotor contacts are clean.

Your video is a great idea. I wish more would follow your lead.

Your absolutly right about the car starting hard the longer it sits. If i turn the car on, then turn it off. It will start no problem.
Also the car is distributor-less. It has no spark plug wires, just 6 ignition coils. And i did check coils resistance and the voltage to each coil. Also the spark plugs were changed less then a wire ago and they r oem denso plugs. So no need to gap them.

Translated - you changed the spark plugs a week ago and didn't check the electrode gap because they were new OEM Denso plugs. Do I have that correct?
Enlighten me. Why don't you need to check the electrode gap on new Denso spark plugs before installing them? Did this problem crop up right after the plugs were changed or did you change them because of the hard starting?
Forgot to mention a primary culprit for no residual fuel pressure at start up is a leaking fuel injector. Were any of them wet when you checked them? Do you smell raw fuel when near the engine?
Some auto parts stores such as Autozone will lend equipment. Give them a call and ask if they have a fuel pressure gauge they can lend you.

Sorry typo, the spark plugs were changed less then a year ago. I also didnt change them, the previous owner took the car to a shop and they changed them. I removed the front 3 spark plugs and they looked okay to me. The reason I didnt bother checking the gap is because I know when i replaced my spark plugs on my 98 with oem denso spark plugs, they told me i didnt need to gap the plugs since they were already the right gap. I'm assuming this car's plugs are the same since both use original toyota denso plugs.
Also I dont think any of my fuel injectors are leaking. I made sure to change the o-rings.
