Using crop effect - exported video still has black bars

[bonaca285094967g2p]

Trying to remove tiny black bars from left and right using crop effect

As you can see - crop rectangle is adjusted properly

But exported video still have that black bars

What is wrong, pls ?

[Richard M Knight]

Effectively your 'canvas' remains the same size, you are just making the video smaller, There are several thinks you could do, use the scale function in the fixed effects to zoom in to lose the black bars. You could also adjust the sequence width  using the sequence settings or uou could lokk at these options on the export page.

Thanks a lot, I will try.

Could you explain please that logic:

Crop tool should crop and not resize a video, isn't it ?

[Suraj5EBF]

Hi, In Effect Control click on the "Zoom" checkbox under the Crop effect, which resizes your footage to frame size in the Program monitor automatically.Then you can avoid the black bar at the edges.

thanks,

I don't want to ZOOM - I want to CROP - i.e. cut black bars

For example - starting dimensions are 640 x 352

If black bars are 10px each - exported video should be 620 x 352

That's what I want

[Richard M Knight]

You need to change the sequence size in the sequence settings.

[bonaca285094967g2p]

Change the sequence size - on what dimensions? 

I dont' know in advance what is the width of black bars.

10px is just an example.

And I'm expecting to get such an info for example by dragging handles on crop rectangle, but there is now such an info.

Or use AME

I dont' know in advance what is the width of black bars.

10px is just an example.

[Ann Bens]

Look at the top of the bar: 10 pixels.

[bonaca285094967g2p]

How did you get this info and this entire window ?

What is AME - a plugin or what ?

[Ann Bens]

You know the dimensions of your sequence, you know the dimensions of your clip > that will give you the amount of pixels for the black bars.

Post screenshot properties clip.

[bonaca285094967g2p]

Here are clip properties

Sequence properties is also 640 x 352

How to know black bars size ?

[Ann Bens]

If your sequence settings matches your clip there will be no black bars.

Check your scaling as Uniform scaling is uncheck and it should not.

Post screenshot entire Effect controls.

If you have no idea what AME is might want to hit the LEARN button.

Premiere has a very steep learning curve.

[bonaca285094967g2p]

Yes - sequence settings matches clip settings

And black bars are inside the clip, as a part of clip,

And I need to cut that part of video - and get smaller video width

Once again - black bars are part of video and I need to cut them.

Why it is so hard to imagine ?

[Ann Bens]

Black bars are inside the clip.............Right, that is information you left out. There are more than one kind of black bars.

You need to scale the footage to get rid of the black bars.

Or change the sequence settings to match the footage without the black bars. (eyeballing).

But then you will get an odd file on export.

In this scenario, crop does not come into the picture.

[bonaca285094967g2p]

how to know - on what size - I need to change sequence settings ?

that must be original size - minus - black bars size

how to know - what is black bars size ?

[Ann Bens]

Use the guides in pixels to measure or just eyebal (trial and error).

[Richard M Knight]

You also have to remember that most video export formats expect an even number of pixels, some may want to be multiples of four.

[Amber22508002sxz5]

This is the correct answer. If 'Zoom' is checked in Effect Controls, the black bars will automatically disappear and the clip will appear as desired. 

Think of it as 'zooming in' to your desired crop while obviously maintaining the same aspect ratio 

[Ann Bens]

Crop means cutting of the edges and not resizing.

If your footage is UDH in a UDH frame you should not see black bars opposite to 4K footage.

Your screenshot shows Uniform Scale unchecked!!

Cropping in Premiere Pro is different from cropping in Photoshop.

In Photoshop, cropping removes the rest of the canvas, like cutting a photo with scissors.

In Premiere Pro, cropping is like covering the unwanted portions with transparency.  The absence of video (transparency) is seen as black. In order to remove the black area, you need to "change the canvas size" which is equivalent to changing the sequence size.

[bonaca285094967g2p]

Very fine explanation

But - if I need to "change the canvas size" I firstly need to know the size of uncovered (black) area, isn't it ?

Or - even better - the size of covered area

And that seems impossible

[307_4601]

So outrageous ah, I just learned to use this software, this function I think should be quite practical, but in the software can not find, is to give a box to let me choose the size of the video?

[R Neil Haugen]

You control the framesize in the Sequence controls menu. Framesize is a critical part of any sequences.

Framesize, framerate, and color space. Plus audio channels. All in the Sequence menu.
