Hi:
I'm a new user and I'm trying to clean 2.36 minutes of this YOUTube up.
https://youtu.be/6VsV-JQrGEs
All I know is that this was live from Guantanomo Bay Cuba in 1987. Filmed by the Navy Broadcasting Service. I repeat I only want to clear up 2:36 (2 minutes 36 seconds. All are dead except Carlene Carter. I'm trying to make a tribute video to the Second Generation of Carter family. Can anyone guide me? Is this doable? I've recently bought Movavi Screen Capture and Adobe Photoshop elements. Any help woould be appreciated.

That YouiTube disaster is not the video that the Navy recorded. It's a thoroughly botched job by idiots who had no idea what they were doing. I don't think it can be repaired. You can play with it if you want, but it will only look worse. Besides, that YT link isn't your copy of the bad video, it's what's left of it after YouTube techs got finished with it.

Your intentions are laudible and it's a very worthy idea, but that video is a real train wreck. You might be able to fight snippets somewhere from other videos that don't look that horrible and you could make some sort of composite memorial from smaller pieces and photos.

There are usually 10 Worst Mistakes listed when making a video from analog tape. That video shows signs of all 10 and invents about 50 more. It's mangled into pure garbage. What a shame.

Ouch.

Main issues =
- no TBC on capture
- unstable tracking
- drop-frame deinterlaced
- VCD conversion likely
- motion error either dropped frames, or sub-30fps, or both
- nth generation copy-of-copy tape source, excess luma haloing

I can do some very nominal things to fix it, but even at 4x6" Youtube window size, it's blah. Show it any larger, and it will just be singing blocks. (Even Lego men would be more discernable.)

We didn't even get to the hissy audio.

Truly, a real shame.

Attached is quickie restored version. Still not great, but nominally better.

Thank You. I'm sorry to be ignorant on this subject. Can you tell me how to put each of these videos side by side to compare your restoration...or can you direct me somewhere that will tell me. I don't want to waste your time. Thanks again.

You'd use an Avisynth script.

Here's my template:
Code:
clip1=AVISource("c:\.avi")
clip2=AVISource("c:\.avi",false).Trim(10,0)

clip1=ConvertToYUY2(clip1)
clip2=ConvertToYUY2(clip2)

# left/right 640x480 source
#StackHorizontal(clip1.crop(0, 0, -320, -0), clip2.crop(320, 0, 0, -0))

# left/right 720x480 source
#StackHorizontal(clip1.crop(0, 0, -360, 0), clip2.crop(360, 0, 0, 0))
#StackHorizontal(clip2.crop(0, 0, -360, 0), clip1.crop(360, 0, 0, 0))

# top/bottom - 640x480 and 720x480 source
#StackVertical(clip1.crop(20, 0, 0, -240), clip2.crop(14, 240, -6, 0))
#StackVertical(clip2.crop(0, 0, -20, -240), clip1.crop(6, 240, -14, 0))

# left/right 720x480 source side-by-side
StackHorizontal(clip1.crop(0, 0, 360, 0), clip2.crop(360, 0, 0, 0))
#StackHorizontal(clip2.crop(0, 0, 0, 0), clip1.crop(0, 0, 0, 0))
spline36resize(640,480) 
#spline36resize(960,360)
That does NOT work as-is. It needs editing. I use it for all kinds of before/after work. Look at that, learn what the scripting means. This is an easy one to use.

I'm not really sure why you need a before/after, unless you're trying to learn.

That was quickly done in Mercalli and Avisynth, with only minimal setting tweaks. Not paid, no time, but just to help you out, be it for using or learning.

Sad to here we lost another one. My dad is always saying that we're losing to many of the great country singers.
