Eliminating an artifact in 2 frames?

Vegas pro V13... I have a video at 59.94 fps. There are a few places in the video where a vertical black line artifact appears in two frames. I would like to remove these lines. I have attempted two methods, neither works.

1. I created a mask around the black line and used a blur. This would work well enough except that there is already a mask needed in those frames. I can't find a way to only apply the blur to a single mask.

2. I took a screen shot of the bad frame and used the clone tool in Photoshop to remove the line. I figured that if I pasted the improved frames above the damaged frames the line would be gone. This has proved only partially successful. The result is most curious. First I reduced the size of the photoshop fixed frame as it automatically is stretched out to 5 sec. I reduced it to cover the 2 bad frames. When the cursor is at the beginning of the first bad frame the line is gone. When the cursor is between the two bad frames the line is visible, and when the cursor is at the end of the second bad frame the line is gone. This seems quite weird to me because I thought that whatever was on top would be shown. How is the bad frame getting through? I also tried extending the good frame to cover more frames but the result is exactly the same.

3. Is there a better way (tool?) to edit single frames? Something like a clone tool in photoshop?

Thanks for any help or suggestions!

Is it in a position that you can duplicate the previous frame and trailing frame, or does that cause a jump?

Thanks DMT3....unfortunately not.

Could you upload a screenshot of the timeliine with the problem visible?

@prejto Hi, can you share a screen shot of the problem frames, full screen but the timeline extended showing the two frames, or maybe even share the file on Google Drive or another sharing site,

I've got a couple of tools/plugins that can repair those frames but they work in a similar way to what you've been doing by replacing the damaged info from previous frames, & the plugins are quite expensive,

When you import and adjust your stills, make sure Quantize to Frames is turned on.

This will not work retroactively. To fix it after the fact, you must zoom in to frame level and drag the edges of the unquantized frames by hand.

That should fix it.

Musicvid, thanks! That fixed the problem. I also found that if I split the jpeg rather than drag it to size that also worked.

Gid, thanks for the post. Would you please share a link to the plugins that you mention? I'm quite curious about them even if they are expensive. Thanks

@prejto Hi, this is Mocha Pro, it's got lots of features, this is the Remove option, this is like you were doing with a clean plate image added on top of your track, this is a very lazy Remove i threw together for you, you've got to imagine the man is the black line or mark on your frames,

The red car that comes in at the end can be tracked & masked so it doesn't get removed, the remove uses trailing & preceding frames to fill in the gap created be the removal of the man, the frames that it uses to fill in the gap can be chosen ie. frames 30-85 .. or in your case it would just be the frame before or after, providing they were good frames

Gid, thanks a lot for taking the time to make up that video! That is most impressive software for sure. In comparison, my problem is quite simple. Just some static random appearing lines in pairs of frames. Anyway, the issue is sorted now. Thanks again!!
