Otherwise, and for other users who might be interested. Try using Avidemux editor, just as a way out.

This example using a Windows 10 VM  https://youtu.be/kMCvcFKnrtY  duration 7 minutes.
Edit: Not going to redo the video but playing around with the latest version 2.8 and it is frame accurate. No need to use key-frames. set the first frame (A) and the last (B) Save Image Selection...

Okay, I'm replying to not leave you guys in the dark.

So I managed to achieve the effect I wanted in Vegas Pro (with some online help) and it took like 3 minutes to set it up.

Here's a 20 second almost out of context clip of that effect which is pretty random since this is somewhere in the middle of my final video which isn't finished yet: https://www.youtube.com/watch?v=1ciK2wd4mFg as you can see the crab is both in the transition in & out. Nothing too fancy but I personally like it when other video editors put tiny details like that in their videos.

Good news is that the 1920x1080 expanded crab image was useful as otherwise during the transition the crab looked quite square. As well as recoloring it white. I can't remember if it was one of you gents who also did that for me.

Also... where did all my buttons go? I used to have more options in that menu before I updated my Gimp two days ago...

The longest wait that I ever had was 6 hours to render an 4 hour looped version of a song because YouTube in the year 2022 still can not afford to give mobile users the ability to loop music videos. This one makes me proper mad. This is from the category of: people in the future will have flying cars! Probably 2035 still no loop function for mobile users on YouTube...

Judging by the fact that you gents are also experienced in video making, I'm guessing that there must be some other help forum that's based around one or another video editing program that I'm not aware of? I have this bad habit of just throwing out the same question in 3-5 different forums and seeing which one will answer first. xD

Also excuse me for 'littering' this forum with my random nonsense post. You can expect me in a year or half a year popping up one random day with an another totally bizarre question.
