Valid custom aspect ratios?

Hello,

I'm trying to "squeeze" a video down to a custom size, so that I can project it onto a white screen that is in front of a window. I've been playing around with the aspect ratios in VLC player, but I cannot seem to get the "perfect" size I want. I need something that's pretty narrow, between 2:2 and 2:3, but I don't know how to create that. My problem is that 2:2 is too narrow, and 2:3 is too wide. I've tried adding a custom list, which looked like this:

Code: Select all

2:2.1,2:2.2,2:2.3
but that didn't change anything. I assume those aspect ratio's are not valid. Is there a way to accomplish this?

Thanks,

-Sean

An aspect ratio is always expressed as a fraction (of two integers).

OK, so does this mean there is nothing in between 2:2 and 2:3?

No? Middle school maths?

I understand the math, what I don't understand is if there is a way to achieve what I'm trying to do. I also don't undstand why some folks feel the need to be rude in a support forum.

I'm not familiar with VLC, and thought I'd ask a question. I guess it was a stupid question. I only hope you don't treat any paying customers like this.

Thanks for the help.

I was not rude and there never were paying customers.

Of course there are fractions between 2/3 and 2/2. Infinitely many even.

You didn't even provide an answer to my question. All you did was explain what an aspect ratio was. Then you made some comment about middle school math. If you don't have time to provide helpful answers, then perhaps you should just stick to developing and leave the technical support to others. As for paying customers, I see you have a donation button... which I would have actually used, had I received actual help.

Hey thanks. Again, what does this explain to your average "Joe" who's new to VLC player? This leaves me with more questions then I had started off with. If there are more fractions that VLC is capable of understanding, how come my example didn't work? This is where a person familiar with sharing information would insert a working example.

Thanks again,

He says you should use only integer numbers in the list of custom aspect ratios, though there are real numbers used in the predefined list of aspect ratios: 2.21:1, 2.35:1 and 2.39:1.

Code: Select all

20:21,20:22,20:23
2:2=2/2=1
2:3=2/3=0.66
So you would like to have some ratio between 1 and 0.66
You can work with bigger integers. Video resolution is probably the most comprehensible way. For example:
640x480 => 640:480=4:3=1.33

That is why I have suggested a "free aspect ratio" feature - 2 hotkeys to make video wider/narrower on-the-fly, without necessity of user's knowledge and manual input of any numbers. Just to watch how a video is changing its proportions while pressing those hotkeys.

THANK YOU!

That is the explanation I needed.
