Notes:
Average is from Oct 23, 2010.
I don't Roux so forgive me for any errors.
Many M / M' / M2 moves are performed as r'R / rR' / R'rM' combinations.
I am not 100% on some of the sequences, especially those crazy fast cows.
This was hard! I demand better camera angles and lighting! =)

Brest, if you have free time, can you try to reconstruct this?

If you can't, don't worry.

Thanks!

PS: You're doing an awesome job with all of these reconstructions :D
Thanks for the appreciation!

So I'm just starting out with reconstruction, anyone got some easy solves out there that I could try?
You could go to the video subforum and choose a solve from there. Or search on YouTube for a solve that you like. To start with, I'd recommend one with a good camera angle and good lighting.

So what's your process for doing this, Brest? What tools (if any) do you use?

If you're feeling masochistic, you can always reconstruct the solves from 1982, only 22.95 has been done so far. We can get you a higher quality video if you're up for that.

Tools
alg.garron to keep track of the solution. This is an amazing resource.
Cube Explorer can be necessary to find the scramble.
Media Player Classic has frame by frame to step through a solve. This is very useful for poor quality videos; like bad lighting, graining/distorting, or those filmed from a distance. Recommended by qqwref.

Process
After choosing a video, the 1st step is to get the scramble. Sometimes it will be listed in the video description, a forum post, or the delegate may have the files. If the scramble cannot be sourced then Cube Explorer is used to generate one.

Finding the scramble
"Empty" the cube and, during inspection, fill in the scramble. Often the whole scramble can be seen during inspection. If the lighting is bad some colours can be hard to distinguish, so only fill in a sticker when certain. Sometimes the video won't show a few stickers, a whole face, or more. When this happens use logic to fill in the blanks.
If this is not possible, then begin reconstruction in Cube Explorer on the partially scrambled cube until the blanks come into sight. Be sure to keep track of the moves made so they can be undone, and as a backup take a screen shot of the partial scramble in CE before applying any moves.
When the video shows the scramble being performed it is possible to just reconstruct those moves. If it is a computer generated scramble, this method could be easy as there should be less finger tricks and very few rotations.

Reconstructing
The solve itself can be relatively easy. Apply each sequence of moves in alg.garron and compare the result with the video to be sure they are correct. A physical cube can also help.
Having knowledge of the method being used is very helpful. Knowing the goal of each step can make it easier to work out what is being performed.
If a sequence of moves is ambiguous, go forward until there is a clear image, then figure out how the cuber got to that state. Knowing more than one way to do each step is helpful here. As an example: in CFOP there are many ways to pair and insert each F2L case, so compare the video to each one until a match is found. Sometimes it may not be possible to provide an accurate reconstruction.

Cube rotations are sometimes hard to interpret. What the video shows may not be what the cuber was thinking/performing. It might be best to use rotations that work for the solution rather than try to interpret what was actually performed.

Video quality & camera angle
If the frame rate is poor the moves can be a blurr.
Bad lighting can make colours look similar.
Camera bob without a tripod is not ideal.
If the angle is bad the cube can go off screen or be obscured by the cuber.
Some angles only show one face during solving which provides less information.
Many videos are filmed so the angle is opposite to the cubers' view.

It can be frustrating, so be patient. If it is not enjoyable stop, have a rest and come back to it.

If you're feeling masochistic, you can always reconstruct the solves from 1982, only 22.95 has been done so far. We can get you a higher quality video if you're up for that.
Sure, I'll give it a go. Videos?

Thanks for the write up! Interesting read.

I'll PM you the link to the high quality video - it's not meant to be public. The lower quality one can be found on youtube.

Good stuff, Brest. If you reconstruct world records, please add a link on [wiki]List of World Records[/wiki]. I also linked from [wiki]BigGreen[/wiki] and [wiki]Roux Method[/wiki].

Hey Brest, I told you I had doubts about reconstructions, but after all, you may be right (nice work by the way).

I had problems to recognize:
U' M U' M U' M' U M'
M' U2 M' U2' M U2 M2 U2 M U'
because it's really hard to analyze... 27 HTM moves in 2.5 seconds! (too fast!)
and because I could not find any excuse for such a bad solution (too fast?)
=> U' M U' M U' M' U' M' U2 M2 U'

BigGreen is wickedly fast, especially during LSE, where his tps bursts are hard to follow.

One of the lessons I have learnt from the time I recently spent doing reconstructions is to disregard the way I would solve it and instead try to analyze what was actually performed. It is very helpful to know what the goal of each step of the solution is; however it is important to be unbiased when transcribing the sequences. Simple mistakes, like (U U U2 U') or (y' U2 y2), are important to include in the solve, as are sequences that are not ideal solutions.

The solution you have suggested is certainly more efficient; however I am unable to match it to the video.

After this sequence:
(M') U' M U' M U' M' U' M'
U2 M2 U'
the U face looks like this:
[cube]size=100&view=plan&case=U2M2Uz'[/cube]

Compared to this sequence:
(M') U' M U' M U' M' U M'
M' U2 M' U2' M U2 M2 U2 M U'
where the U face looks like this:
[cube]size=100&view=plan&case=M'U2M'U2'MU2M2U2MU'z'[/cube]

From the video at this stage of the solve there is this image:
As you can tell, I spent a lot of time with this video while reconstructing. I am not saying they are 100% correct, but I believe they are very close.

Again, thank you for your comments, it is not often I get to 'chat' with the inventor of a method! :tu

Yes, sure! That's what's matters in your work: Analysis of real solves.
I was just saying that he is too fast on the video for me to understand what he does, and when I try my own solutions, they do not match. There's a possibility he was too fast to see some obvious options, and that's where your work is interesting. If you reconstruct a series of 100 solves from him, maybe we could show BigGreen how he could be faster. ;-)

Really? There seems to be dozens of method inventors on this forum!

Notes:
I have tried to interpret how the M/M'/M2 moves are performed.
Also included is the sequence without this interpretation.
M2 as (r2R2') is closer to (rLl'R') - probably for comfort.
M2 as (R'M'r) is sweet!

Yes, sure! That's what's matters in your work: Analysis of real solves.
I was just saying that he is too fast on the video for me to understand what he does, and when I try my own solutions, they do not match. There's a possibility he was too fast to see some obvious options, and that's where your work is interesting.
"Slow down & look ahead" Vs "High tps Go!Go!Go!". It would be nice if there was a way to find the perfect balance between the two. I can only guess that with such fast turning it is common to miss an optimal solution; however there must be solves where it is not missed.
With this example, it would be interesting to know which would have been faster: the solution Big Green used, or your solution plus the pause to see it. In this case there is a large deviation: 7stm / 10sqtm / 11htm / 14qtm

If you reconstruct a series of 100 solves from him, maybe we could show BigGreen how he could be faster. ;-)
*Challenge Excepted* Wait 100 solves?!? Maybe not! =)
I am definitely open to reconstructing more solves from Big Green, but he has only uploaded a 6.64 single recently and I had trouble seeing the cube through his hand! I may try an earlier one, but a current video would be better.

I looked on YouTube for some of your solves and the only ones I found did not show inspection, so it would be hard to find the scrambles. If you are interested in some of your solves being reconstructed I am willing to try.

Really? There seems to be dozens of method inventors on this forum!
That is true, and I meant no disrespect to the many cubing masters on this forum, but you invented Roux! You *are* Roux! ;-)
