Not too bad at all.

Could it be better? Yes. Would the quality be vastly improved when professionally scanned? Yes.

But the thing is - if you're satisfied with the result, then no need to spend any further $$ for something you don't really need, and the story ends here.
(I kinda understand this. Not everyone need to have all films transferred at absolute best quality in every single case.)

Hi!

The main problem is that the original film has not the best quality: no tripod, camera used in „snapshot mode“ (=unsharp scenes), not pressing the „backlight correction“ button, ignoring the camera’s over-/underexposure warnings, later shooting indoors with a single 1KW halogen light, not setting the filter key for the „Wratten 85“ correctly, …
… Hence, I don’t know whether a better transfer is worth the money. (Even though the film is of historical significance as it’s my first appearance on the big screen. )

I also slightly improved my setup in later attempts that have still been mainly a test whether I could get the same or better results with an outdated iPhone7 than with one of those Winait scanners.
I‘ll now have to check whether my new smartphone will give better results. But this will take some time due to my job and several other spare time appointments.

Good try Joerg,
As a quick test you can compare the quality of the projected image to the scanned image.
I believe your video can be sharper judging by some hairs in the top right corner that are out of focus.
You can also project directly to the iPhone keeping the original lens in the projector but would need to replace
the light with the led.
Here is an example of direct projection to the iPhone.

This webpage claims that I would also need a special lens for the projector.

Is this correct?
(At least their app would automatically mirror the image.)

No special lens is required in my opinion. It is just the way they worded the description of the product that make you think that you need a special lens but they are actually referring to their lens.

BTW - when using the iPhone for transfer, the projector and the phone have to be on a very sturdy surface. The iPhone mechanical IS has the sensor suspended on springs and they use electromagnets to move it for IS. The issues is that certain vibrations like projector vibrations cause the sensor shake that the IS can not counter for and you get a shaky video. So a soli surface is required and the phone should not be touching the projector. I developed a custom lens for iPhone X that gives around 2X optical mag but unfortunately I did not see any improvement in final resolution as compared to the direct transfer. Still working on that.
