What's the original resolution?

[tebasuna51]

Maybe because your source is already 1904, use MediaInfo to know your source (in logs there are the MediaInfo data, post full log)

- Is your source anamorphic? If not don't use 'Clever (TM) anamorphic encoding'.

- Are you encoding to XviD or h264? If you are encoding to h264 select 'Encode non-mod16' in 'Clever (TM)...'

- If you use 'Clever (TM)...' with h264 video use Crop but not Resize.

[hello_hello]

As well as what tebasuna51 said (probably no point using anamorphic encoding if the source isn't anamorphic) click the config button next to the Avisynth profile dropdown box and check to see if "upsizing" is enabled. For reason's I'll never understand it's disabled by default.
As the resizing when using anamorphic encoding attempts to keep the width/height ratio as close to the same proportions as the source as possible (you can't freely resize them both with anamorphic encoding) and you're cropping and forcing mod16, that might be effectively forcing a width reduction to 1904 if the "upsizing" option is disabled, which it is by default for reasons I'll never understand. :)

It's very strict and when "upsizing" is disabled. I'm pretty sure MeGUI will always resize "down" to the next mod (ie mod16) rather than resize up, even if it's only by a few pixels (1080 - 138 - 138 = 804). Of course if "upsizing" is disabled, which for some reason it is by default, and your source is actually 1904, you'll have to enable it before you can set the width to 1920.

I wouldn't bother with anything higher the mod4 for x264 encoding. Even mod2 is probably fine 99.99999% of the time. I've never had issues playing mod2 video with a hardware player, although I usually stick to mod4 just to be paranoid.

... and check to see if "upsizing" is enabled. For reason's I'll never understand it's disabled by default.

For me "upsize" must be disabled by default.
Of course the user are free to enable.

If source is 1920x1080 and after the crop(0,138,0,-138) -> 1920x804

What is the problem to encode this resolution with x264?

We don't need anamorphic encode, mod16 or resize at all.

this is complete info

PS - guys i m new to this technical language,can u pls simply tell me settings in simple english :)

[Groucho2004]

I understand that you just want to crop so uncheck the "resize" and "clever..." boxes.

I need anamorphic so I check "clever"

Also see my description and let me know how to figure if source is anamorphic or not,so that will help me

[sneaker_ger]

DVDs are always anamorphic. Blu-Rays only if they are 1440x1080, 720x576 or 720x480.

[hello_hello]

For me "upsize" must be disabled by default.
Of course the user are free to enable.

If source is 1920x1080 and after the crop(0,138,0,-138) -> 1920x804

What is the problem to encode this resolution with x264?

We don't need anamorphic encode, mod16 or resize at all.

I agree. I was just pointing out that it's probably the combination of anamorphic encoding being enabled and "upsizing" being disabled that's causing MeGUI to reduce the width, and probably also because the mod is set to 16.

The main issue I have with upsizing being disabled by default is the setting is buried in the Avisynth profile setup (new users often don't look there) rather than in general options, and it's not "anamorphic smart", so resizing a PAL DVD to 1024x576 (for example) is considered "upsizing" and therefore MeGUI won't do it by default. It's also very strict. Before MeGUI had an upsizing option (when it wouldn't upscale) it'll still upsize a little. You could crop a couple of pixels from a 1920 width and resize back up to 1920. You can't do that anymore. You have to resize down to the next mod, unless upsizing is enabled because you know where to find the setting to enable it or that it even exists.

An anamorphic source (in this context) is any source with "non-square" pixels such as a DVD. That means the resolution and display aspect ratio are different. An NTSC DVD is anamorphic because the resolution is 720x480 but it can display as either 4:3 or 16:9 and 720x480 is neither of those aspect ratios. 720/480=1.5

When the resolution is non-anamorphic the resolution and display aspect ratios are the same. ie 1280/720 = 1.77777 = 16:9

[Sharc]

I need anamorphic ...

Why? Your BD source is square pixels.

....let me know how to figure if source is anamorphic or not, so that will help me
- Open the file in MP-HC
- Right click into the picture => Video Frame => Aspect Ratio => Assume square pixels
- When the picture looks squeezed (egg heads) it is anamorphic.

[hello_hello]

An easier way with MPC-HC is to use the File/Properties menu. If only a resolution is displayed, the video is not anamorphic. If a resolution and aspect ratio are displayed, it is anamorphic.

An anamorphic example:

Not anamorphic:

https://s24.postimg.org/j7qt23g3p/anamorphic_not.gif

[Sharc]

An easier way with MPC-HC is to use the File/Properties menu....
Doesn't work when the Aspect Ratio is set to "Default (DAR)" in MPC-HC. In that case even an anamorphic video is shown as a resolution only, like 1024x576 for a PAL DVD for example.

[hello_hello]

But I have it set to "Default (DAR)". Honestly.....

https://s11.postimg.org/pudafa63n/mpchc.gif

[Sharc]

Strange ....
Did you try with an anamorphic 16:9 PAL DVD?
I am getting 1024x576 only, without any additional (DAR) indication.

[hello_hello]

Which splitter/decoder are you using? It's probably the splitter's job to pass that information on. I'm using the internal LAV splitter and decoder.

It was a bit schizophrenic regarding the aspect ratio. Probably because the monumentally annoying DVD menu was 4:3 while the movie was 16:9.

https://s16.postimg.org/pqo6020n9/mpchc.gif

Edit: That's odd. I just noticed it's showing the video steam as 720x480. Maybe the DVD menu is NTSC?

[Sharc]

I am using the internal LAV splitter and decoder as well.
Anyway, that's why I prefer to always view the picture at PAR 1:1 (as stored) rather than solely relying on numbers which are reported by tools - not knowing what's going on under the hood ;)

[hello_hello]

I'd be keen to know why MPC-HC reports aspect ratios differently for you though. It's always worked the same way for me, as has MPC-BE. There must be a reason.

A couple of years ago I discovered under certain circumstances MPC-HC was getting the math slightly wrong (https://forum.doom9.org/showthread.php?p=1698507#post1698507), but that was fixed and it's always worked the same way for me since.

[Sharc]

I notice that the difference is only how it is presented, see example for anamorphic:
http://www.mediafire.com/view/48lc2440a3z4fos/pic1.JPG

[hello_hello]

I've never ever seen it like that. Could it be a renderer thing? Or maybe video card drivers? Or Windows? I'm still using XP.

Sometimes the "video size" aspect ratio, and the aspect ratio listed in the video stream are slightly different, I believe due to the AR in the video stream not always resulting in whole pixel dimensions, so the AR displayed as "video size" is rounded to whole pixels, but I've never seen it display as anything other than 720x576 (AR 16:9) etc. Never as it's displaying for you. Maybe it's my PC that's odd...... but either way I'm curious as to why it's different.

[hello_hello]

So it turns out, if I switch to MadVR as the renderer.......


MadVR vs VMR9.
