cropping the sides to make fullscreen

[anime12345]

Hi I have always hated black bars on my tv taking the top and bottom space..
Now yes I have studied on the internet about aspect ratios letter boxing and how movies are filmed..

so there are two possible ways to remove it is zoom in or crop the sides... no stretchingg
Now I ill use megui to crop and re-encode.. but how much to crop the sides how to know that...

for example I crop top and bottom 138,138..how much to crop to the sides.. (MANY HD movie channels show full screen movies by adopting this method I guess)

Just because they're ignorant fools does that mean you have to be one as well?

After your cropping is done find out the remaining height. If, for example, it was originally 1080 pixels high and you cropped a total of 276 rows of pixels (138 + 138 = 276) that leaves 804. Multiply that by 1.778 to get 1429.512. Subtract that from the original 1920 width to get 490.488. You'll want to crop by at least Mod 4 (final number divisible by 4) so you want to remove a total of 492 columns of pixels from the sides.

Better would be to use the zoom. What you do on your own won't look any better and could wind up looking worse. And by doing this you lose a quarter of the picture. That's why it's a very dumb idea.

Depending on your output file type, you could use VidCoder (a gui for handbrake). When you perform cropping, you can view a sample before spending the time to make a full encode.

Having said that, I'm in the camp that you should leave it alone. I don't understand why people think seeing black bars is worse then cropping off part of the picture and not seeing everything.

Essentially I suspect it is a psychological problem thinking that since I paid for x square cm of screen it should be filled at all times and if one is old enough to remember the problem with plasma screens and burn in. Of course whenever one goes to the cinema there are black bars on just about everything you see albeit in the form of black curtains or movable screens. The actual screen could well be as large as the proscenium. A lot of unused white or silver screen tut tut.

It's a fascinating phenomena that appears to be more prevalent in North America for some reason? Used to be a bit of an issue in Oz back in plasma days but TV stations here steadfastly only showed the theatrical release as is. I suspect it was cheaper for them. A happy event actually. Probably there is a PhD to be gained in studying these folk. Maybe someone in Primate Studies could take up the challenge?

On the contrary, what I hate is when TV broadcasters decide to cripple the original work by eliminating a substancial part of the video just to meet some people's misguided preferences.

And I add IMHO so you don't flame me
