Keep 16/9 cropping ratio

Hi Handbreak community!

Most TV display are now 16/9, could we force the 16/9 ratio for Width and Height (Picture Settings Size tab)?.
:idea: While cropping a video, in the same way as the existing "Keep Aspect Ratio", just add a "16/9" check-box. :idea:
The math are straightforward :wink:

Please support and comment this feature, and contribute!

I'm unclear if you want the video distorted or some kind of bootleg pan&scan?

For 4:3 sources do you want the top and bottom chopped off, or the picture stretched to fill the width?

Similarly for 2.4:1 sources do you want the sides chopped off, or the picture stretched to fill the height?

I guess he wants the "optimal" way -> no stretching, simply cutting the width or height, depending on what is too big to achieve 16:9 ratio

Yes Djfe, that's exactly what I mean. To keep the best of the video to fill in the screen.
Would it be possible?

I guess what mduell wanted to say is: there are several ways and there is no real "default" way and some people might expect different results

though I think the "optimal" way described above is probably the most common case

A cropping option that keeps the 1920/1080 pixels ratio at the better width or height of the picture.
Exemple:
- video 800x600 is cropped at 800x450
- video 1280x600 is cropped at 1066x600

Meh. This would be convenient, but not advisable; better left to manual intervention IMO.

May be better anyway to let your teevee do the cropping if you want full screen display.

That's the problem with cropping 4:3 or 21:9 material to fill a 16:9 screen; the "best" of the video will change repeatedly due to the framing for each scene/shot chosen by the cinematographer and director. The "pan" in "pan&scan" refers to manually reframing each shot during the conversion.

@TedJ, you are right for TV pros that prepares videos movies for TV broadcast... and they are not using Handbreak to pan&scan. :roll:

On the other hand, I am a simple video user of Handbreak. And with my experience, I never get annoyed by a movie I cropped using Handbreak.
This 16/9 cropping feature will help people like me, to easilly compress videos for TV watching, without doing the 16/9 math each time. :)

Problem is, cropping is a destructive feature, and such things are unpopular among software users and developers. Your teevee has all the options it needs to fill the screen.

First you can save space by cropping during encode
Second even in VLC it's not easy to tell him to crop to 16:9 so that you get full width not only in full screen mode but also in windowed mode

Press "c" until you get 16:9??

well, that will probably work, haven't looked into it much
I don't need this feature in particular anyway, since I use autocrop in Handbrake (so that the player can decide how to show it)

I just wanted to say that it might make sense for some people, but in the end it's up to the devs
