There may be an easier way to do this, but one quick method would be to duplicate the track, then use track motion on the bottom track to stretch the edges of the image out a bit. Also, if Vegas Pro doesn't have a repeat edge pixels option, Vegas Effects might, as it is more akin to After Effects, which this tutorial is for.

That seems to keep it from looking white, though the transparency of the edges makes it still stand out.
I'm guessing VE can be used as a plugin in VP? If that's the case, then that might be the best option for me if there aren't any other ways around it in VP. Though I'd obviously like to exhaust my options before buying.
Is there any way to buy it without getting Post?

No, Post is the only way to get it. VE is a stand alone app, much like AE is vs. Premiere, but you can send a video file directly into VE from VP17 without rendering, add effects to it, then send it right back into Vegas, again without rendering anything, to be finally rendered from Vegas Pro.

There is a demo available, so be sure to check that out.

I'd wait for a few other users to chime in, I'm sure for this particular effect there is something that can be done strictly within Vegas itself, but Effects is a very powerful program that I would recommend having anyway.

You can post images to this forum. Use the upload button.

What I can see looks like oversharpening with blown edges. There are techniques that will avoid destructive high-pass sharpening.

I didn't see your images at first... after looking at this, I agree with Musicvid. Try to fine tune that sharpening effect.

I'm not quite sure I follow. The blur is there by default. I only sharpened the image so I could point it out.

Then post your original image, using the upload button, please.

That is not an original image, it is a screen shot.

I'm editing a video, not an image.

Then post a snapshot of your original image with the capture button at the right of the toolbar.

Use the interactive tutorials for beginning instruction in using the features of your new program.

It's not really that visible, but I'd still like to remove the fade on the sides. The reason I posted here was because I could not find any results when I tried to google solutions. I found this video (below) showing how to fix the problem in Premier, but no google result I could find would show how to do the same in Vegas
(2:52)

Oh, it's analog game footage. Sharpening will make it worse. I suggest Neat Video, a paid plugin.

You try blur of another? Sapphire Blur produce no fade. paid but another free?

I'll look into that at some point. Though, that's not what I was talking about. I wasn't sharpening it to fix the problem, I was doing it so the white fade I was talking about on the left and right edges of the screen were more apparent so you could see what I was talking about. Look at the video that I linked to at the timestamp next to it. The man in the video mentions "repeating edge pixels' while using Adobe. I have done several google searches trying to find out how to do what he did in his video because I don't want the columns on the sides of my video. I have not found anything remotely close to an answer. They aren't a big deal, but I would still like for that specific problem to be fully resolved.

I've read about the darkening on edges while applying gaussian blur and repeating edge pixels.

However, I still do not understand what are you trying to do.

Do you have footage that already has the darkness on edges and trying to remove it in VP?

OR

Are you trying to add blur somehow in VP (as external blurred part on your game screenshot or external blurred part while editing vertical video) and trying to avoid the edge darkness?

If the last one, I think external plugin should do the trick.

@Seraph1998 In the FX Chain, try to move Sharpen FX before the pan/crop root.

Sharpen after:

Sharpen before:

The effect change slightly (adjust it) but the unwanted edges are fixed.

Or apply it to the Media FX instead of the Video Event FX (same result about edges fix but almost the same result about pixel sharpening, choose what you prefer).

@Sylk The columns still show up even when moving the sharpen fx around and applying to media instead of event.

The problem has something to do with the alpha channel, so sharpening won't fully remove it. Also, any amount of sharpening just kinda kills the already poor video quality.

@fifonik Basically I'm trying to remove the transparency blur on the video's edges, like how the article you linked to shows. The problem is that the transparency is in the video and shows up even if I crop the video and have no effects applied.
I'm trying to figure out if VP has an equivalent to the repeat edge pixels in AE.

@Seraph1998

Keep project proportions to source proportions and render with same size.

Or stretch source width to frame width: no proportionnal will stretch video / proportionnal will crop top/bottom.
