Using PD16 to try and sort a problem out for a friend who has videoed himself playing the keyboard

As you can see the one image shows the original video set up - equipment restrictions stopped him changing from this

The second image shows the rotated version.

He wants the square on view of the keyboard but without losing anyh of the keys in the image - is there anyway of losing the black bars showing at the side of the view

Or is there another solution to this

thanks
Andrew

Quote ... the square on view of the keyboard but without losing anyh of the keys in the image...

NO.
science executive officer from the Star Trek would say 'it's illogical'

you can test it yourself. take a landscape picture and portrait picture. combine them. you'll see that only middle square overlaps. so wanting '...without losing anyh of the keys in the image' is IMPOSSIBLE.

next time take both ways.

Here's visual proof of what PepsiMan is saying:

You have to choose between having no black edges or no missing keys. Personally, I'd leave the video exactly as shot since that's going to be the most useful for the viewers.

If your friend wants to improve this for the next video, have him set up another phone or camera directly above the keyboard looking straight down. That way he can have a picture-in-picture view of whichever camera is most relevent - him demonstrating/talking/playing or the view of only his hands and fingers on the keys.

Yes there is. PD16 has some unique tools to fix this. See the screenshots of the PiP Designer and the Preview screen. You can fit that Parallelogram into a Rectangular screen with all keys shown.The Blue nodes at the corner allow freehand distortion to fix it All keys are shown and no black bars are seen.

At first I agree with the PepsiMan's science officer and then with Optodata’s screenshot and still do, but I remember answering a similar post a few months ago and gave the solution.

You can't fit a square peg into a retangular hole unless you distort it!!

Wow, I wholeheartedly agree! I've used the key frames to square up overhead video, but I wouldn't have guessed that you'd be able to stretch out this example so beautifully. Great job!
