Making brightness/contrast of one frame same as anotherr

[Mephesto]

What are some good tools to even out the brightness/contrast/histogram of two videos, because I'm obviously doing it wrong.

maybe colourlike ?

or if you wanted to do it manually with scopes, levels, curves etc..?

Wow I didn't even have the balls to ask specifically for something like this because I didn't think there was such a tool.

I did on the other hand ask for such a technique for auto-adjusting one audio file's EQ to match another to fix dull recordings and it turned out there was.

Thank you, PDR.

HQ, LQ after colorlike():

So Jagabo thanks to your Frame matching script a few weeks ago I was able to match the LQ frames of this obscure video I got a decade ago to the HQ. Despite the old MPG fps being 24, the actual fps is only 8 (I estimated 10).

You saw what garbage the LQ vid was but it was kind of nice back in the dialup days to have a 5 minute video only 4500KB.
With x264 using the exact same bitrate (I actually got it with exactly crf18, lmao) and using purely SSIM for comparison, x264 has 7.5x the efficiency on this 160x120 clip. It looks really good too but flaws are visible once you have the original to compare.

I have no idea what crappy MPEG1 encoder/settings the LQ vid actually used because I used TMPGEnc with the best settings and got WAY higher quality. Comparing again to x264, this time it got 2.65x better efficiency than MPEG-1. But I'll assume no such high quality MPEG-1 encoder existed back in 1999 and nobody used the slowest settings.
