How to remove the letterboxes? (aka black bars)

[farmdve]

I am using VirtualDubMod(tried just vdub as well). I am using it in combo with avisynth. I want to resize a clip(upscale or downscale aka either) but remove the black bars(aka i think its called a letterbox).
I have tried the Crop function but its too difficult and doesnt let me use zero values(0). I tried the null transform filter in vdubmod but vdubmod and vdub dont display those black lines so i cant crop them
Can anyone help?

Thanks in advance!

[mgh]

are you seeing black bars/letterboxing in the virtualdub or virtualdubmod preview?

[farmdve]

No i dont thats the funny thing. They appear when i play the vid but on vdub(mod) they dont and i really want to remove them

[poisondeathray]

If they are not visible in vdub/vdubmod or avsp, the it's likely a 1:1 PAR video and playback issue.

How are you playing this back? (what software or device?)

What format is the video? Use mediainfo if you don't know.

There is nothing to remove. It is a 2.25 DAR, 1:1 PAR movie. The letterboxing is normal, otherwise the aspect ratio would be off. You can instruct your media player to stretch to fit, but the aspect ratio will be skewed (circles will look like ovals..etc..)

[Keiyakusha]

If red is your video, blue is your screen, then black bars are normal. All you can do is overcrop or stretch your video but this is not good idea.

If you using KMPlayer with EVR custom renderer on win7 - it adds some black bars to the video, this a bug in KMPlayer...

[farmdve]

It appears on BSPlayer,MPC-HC and maybe even VLC.

EDIT: Ok, so how do i change the aspect ratio?

[Keiyakusha]

First is your video. You can stretch (2nd) or crop (3rd) it.

Use MPC and have it stretch the video to fill the screen.

I don't really mind the black lines when watching movies and such, i just wanted when converting a movie for a phone(320x240) those black lines to not be there

[mgh]

maybe you would like to take a look at this

which might give you a compromise between bad distortion and letterboxing without sides being cropped out.

[farmdve]

@mgh i didnt understand that.

Anyway Keiyakusha explained why there are these letterboxes.. Another thing: When i use avisynth's resizer LancozResize and resize the video to 320x240 it goes from 16:9 to 4:3. How do i keep the original aspect ratio? Aka WITH the bars?

Not sure if I understand you right, but if your source video is 720x320, you should resize it to something close to 320x142. I like 320x144 because of mod16 height. If you want to have actual borders, you should add something like Addborders(0,98,0,98) after resizing.

I searched google but it didn't give any definitive answers to what mod16 is. So, what is mod16?

[MatLz]

Resolution called 'Mod16' is a resolution you can divide its height and width values by 16 and give you an entire number.
Examples: 160/16=10, 176/16=11, 320/16=20, 592/16=37.....

I still didn't get it
When you divide a resolution like that it gives a small number which can't be used on a video
I've never seen a video with 11x20 for an example

Maybe cause my bad english...:(
But maybe 99.999% of people have understood...:)

Downloads... that's a bit of an obvious rule 6 violation!

I don't think having a folder like that is a problem.
Freeware is free, no?
I have removed it from the main post so the problem(if any) should be removed

Closed for rule 6. Don't do it again or strikes will follow.
