Make a mask for the planet. Remove the transparency of the planet. What's the difficulty?

The planet alpha channel is part of the clip. The planet itself is partially transparent. I've tried all the compositing modes. How do I "Remove the transparency of the planet"?

Upload the project with all the files to the file sharing site.

@Deuce Right click Properties - Alpha channel - None.

Before

After (+Bezier mask)

But if you want to only see part of the planet you'll prob have to add a curved bezier mask (Properties - Alpha channel - None.)

Or create a black & white mask, if the planet is supposed to fade away then feather the edge if not don't feather it. (Properties - Alpha channel - None.)

Of if you've got Vegas Mocha you can use that to mask.. I think anyway, I have Mocha Pro not Vegas Mocha s can't test it for you.

Issues related to the project are resolved in the project. Because it is not known what the conditions and nuances are there. We need a project. And all the materials. Otherwise, you can come up with 100,599 options.

@Deuce Right click Properties - Alpha channel - None.

Thanks Gid. That sounds like exactly what I need but when I set alpha to none I get this weird mess.

@Deuce Sorry I have no idea what that is, you need to upload screen captures of the Vegas UI, mention any effects or compositing blend modes ..

We need you to upload at least the original (transparent) planet clip you are using.

Sorry guys. I was away for a couple of days. Here's the planet PNG.

I wasn't aware that .jpg images have or have ever had an alpha channel (i.e transparency or opacity) - to do that you need a .png image with an alpha channel enabled. When you say that your targeted image is semi-transparent - yes it is but it is only semi-transparent within the composite image created by that image's artist - the .jpg image itself has no transparency.

Two possibilities:

1. Contact the image's originator and see if you can get - maybe for a fee - the planet image as a .png with alpha file; or

2. Import the .jpg image into an image editor such as PhotoShop or PaintShop Pro and use the erase tool to remove everything around the planet - which creates an alpha background - and then use something like PaintShop's Clone Brush to effectively copy/paste 'clear' nearby areas to replace the stars - and then save/export as a .png file which can then be imported into Vegas Pro where an alpha channel can be selected by R clicking the video event and going to Properties/Media.

@Dexcon The jpg picture in the OP is of the finished composited piece, the OP is asking about the overlayed planet, the only mention of jpg is by you & the OP has shared a png in the comment above yours.

@Deuce 😂 I get that, turning off the alpha, I've only just loaded it so I'll have play 🤷‍♂️😂

Opening it in GIMP is interesting, you can se the ring but in Vegas there's no ring.

There's transparency throughout the whole planet so masking wouldn't remove the stars, you need an image that isn't completely transparent that you can then add straight in or isolate, key or use a mask

... the only mention of jpg is by you & the OP has shared a png in the comment above yours.

I did see that, but even though the OP mentioned .png for that image, the only download option was .jpg. Did you get a .png download for that image?

@Deuce If you want realism then it would look something like this, although half the planet is in shadow it'd still be blocking the stars, there's no more detail of the planet on the dark side so you'd have to add that in a photo editor i think.

@Deuce You could try something like Mask Generator.

(I didn't have any other footage, so I used the default image.)

@Dexcon Hi, I didn't save it until after I wrote that comment, sorry, no if I right clicked & Save As it does say JPEG but saves as a JFIF file, I don't know what a JFIF is apart from what I've read where it does mention jpg but it has transparency, I was going to ask is this the orig file with it being shared like that on the forum?

I right clicked Copy Image

& pasted into GIMP it auto recognises & wants to export as a PNG 🤷‍♂️

& MediaInfo say this about the JFIF

Here's the planet PNG.

Er, that image is tiny - certainly much smaller than the planet shown in your first post.

But it does exhibit the properties you describe. Ok, so there are several ways of dealing with this. The one I used was

Tracks:

Track 1 Planet

Track 2 Background plate

Track 3 Solid colour plate set to a colour similar to that used in the background plate near where planet is to be seen (or, possibly better, a colour gradient based on the background colour)

Then use oval Bezier mask on Track 2 to outline the planet, and Invert the mask (i.e. we are making a hole in the background plate the exact shape and size of the full planet). Might want to add a second mask to this plate for the mountains

And that's pretty much it

This is a quick result I get with this method and using your low-res planet PNG

Yeah, that's what I figured. It's weird that Vegas doesn't show the ring.

I'll give this a try. The image I uploaded was 4k so it must have been downsized when uploaded?

>The image I uploaded was 4k

The embedded image is tiny, but links to a bigger image! But the bigger image is a jpeg (and thus no alpha). I suspect this site is reencoding it for size purposes.
