Default quality is 75, and here's notes from the manual:
The -quality switch lets you trade off compressed file size against
quality of the reconstructed image: the higher the quality setting, the
larger the JPEG file, and the closer the output image will be to the
original input. Normally you want to use the lowest quality setting
(smallest file) that decompresses into something visually indistin-
guishable from the original image. For this purpose the quality set-
ting should be between 50 and 95; the default of 75 is often about
right. If you see defects at -quality 75, then go up 5 or 10 counts at
a time until you are happy with the output image. (The optimal setting
will vary from one image to another.)
-quality 100 will generate a quantization table of all 1’s, minimizing
loss in the quantization step (but there is still information loss in
subsampling, as well as roundoff error). This setting is mainly of
interest for experimental purposes. Quality values above about 95 are
not recommended for normal use; the compressed file size goes up dra-
matically for hardly any gain in output image quality.

Looking good I can't tell the difference.
We may even be able to take the number lower.

I've noticed that we haven't been doing much to compress our JPEGs.
Therefore I created a new application, Crushed JPEG, which can convert various images to Crushed JPEGs.
Usage is: crushedjpeg input.image output.jpg
Or
Usage is: crushedjpeg input.image output.jpg 85
The last parameter here is quality to preserve (0 - 100).
On default settings, I cut several of our JPEGs in half, and didn't notice any significant quality loss.
Please play with this and post comments.
Edit: While this can compress from JPEG, it's always best to compress directly from a lossless source (yes, from PNGs is supported).
Edit 2: I'm not compatible with 3D, so I don't understand what I'm looking at, so I'm not the best judge on quality here, but with default settings:
2443M.jpeg.jpg: 43827
2443M.jpeg2.jpg: 9816
Difference: -34011
I can't tell the difference, and that's a huge size savings. (Which would work better if done from a lossless original source)
(If you can tell the difference, you're free to tweak the quality setting.)
Edit 3:
Another test with lossy source using default settings (would be nice if someone can test with lossless source).

TASVideos and TASing will be demonstrated this year at AGDQ 2015.
Offering prizes will increase viewership of the TASVideos block, and serve to further promote TASing as well as raise money for charity. dwangoAC is coordinating the effort and representing TASVideos at AGDQ 2015, and needs your help putting together these raffle prizes. Video game and/or TASing related donations and ideas are welcome.

Okay, now should I restore the other 2 runs' branches? And should the current UMK3's branch be glitchfest instead of playaround (to highlight the content and be true to the submitted branch)?
Those two other runs are for the identical game, which has the same characters and mechanics.
I haven't watched them in a while, but IIRC, the longer of them copied nearly all the antics of the shorter, but did much much more. Which if my memory is accurate, it is correct that longer obsoleted the shorter.
I don't really understand what the difference between Glitchfest or Playaround is, but Glitchfest is accurate to what the runs does, so I have nothing against it.

Nach: there actually exist playarounds of this game already.
It's not the same game.
However, if there already exists a run which is very similar, then this run should be rejected or obsolete another.
IMO, since this run has a character in it which isn't in the others, and the others have characters in it not in this one, and the mechanics are a bit different, and even though many of the moves are similar, this one has a style and glitches that are unique onto itself, it has claimed a right to exist along side the other ones.
In short, I find the game differences and the run themselves differentiated enough that they can exist alongside each other.

You're welcome Dark Noob.
Good quality and differentiation from the runs for other games, and the audience feedback to back it up is all you need.

I must admit that if you are being sarcastic, you are confusing me about the fact.
I will assume you didn't say that seriously.
I'm not sure why it's not obvious. Let me help you out:

I don't see how anyone can seriously consider that* a beautiful lady thread, nor consider its contents as being hijacked from the supposed us.
Aqfaq is doing an admirable job acting as the battered woman, but with remarks like this, its sarcastic facade should be apparent.

Yes, I'd agree with that understanding of it. However the statement itself taken out of context can be construed in other ways, which I think is why some people find it racist.

You are seriously equating "there are no women on the internet" with racist jokes?
From his point of view (and probably others I imagine), they find that to be a racist joke, as they feel it carries some kind of connotation that "women don't know how to use the internet" or "women are better suited to stay in the kitchen than go to the internet", or something along those lines.
However, I like you see it more as a joke regarding the internet itself, and its anonymity and ability to utterly misrepresent oneself during communication, than anything related to women in particular.

You do realize that there's some really nasty harassment that happens in person to women when they're noticed on sight, right? I doubt it's any worse on the Internet than in person, except that some people think that if they harass someone on the Internet there won't be any retribution, so they can be a lot more bold and do things they wouldn't do in person.

For example, the mods could have instituted a zero-tolerance policy and said, "At the first instance of sexual or other harassment, we're doing away with the gender option."
How about on first instance of harassment based on gender, we're terminating the offending user in question?

For those of you familiar with the Effective C++ series, the latest addition, Effective Modern C++ is now available, and also for one more day only, you can get $10 off (code BOOKDEAL25).
If you're unfamiliar with the series, or want to know more about the various books and a quick review on this one, here you go.

All the more reason why someone should TAS the arcade or other equivalent platform.

Every game comes out of the factory with a clean SRAM (either wiped to 00/FF or with some specific values the game expects). You have to start with that. (You may start with arbitrary values if you can provide a TAS that creates these values.)
Anything else is like hacking the game or using cheat codes.
Assuming it has SRAM. I've also seen Electronic Arts Games come out of the box with SRAM initialized to 0xEA, which I doubt the game is necessarily expecting.
But everything else you said is absolutely correct.

Just out of curiosity, has this been proven for the default state of the accepted emulators?
I can't speak for every emulator. I do know some emulator authors have ensured their emulators start from a valid clean slate.
For the few emulators that this hasn't been done, the least I can say is that everyone has the same starting point, and it's not a free for all with no care given at all, and the starting state selected by the emulator isn't one specifically designed to influence particular games in particular ways.

Take apart the hardware and examine it.
So a validity proof requires achieving that state on hardware? That seems rather strict.
Since the vast majority of states are invalid, and we've selected a fair identical starting point for TASs, if you decide to tweak things in your favor, then it is upon you to also prove such starting point is valid. TASing is supposed to be about what is possible with the game and its system given the perfect player, not about what you can do if you modified the beginning to an impossible state given the circuitry in question.
Derakon wrote:
What if you're reasonably confident that a state is possible, but it has low odds (like 1 in 10,000)? Do you have to keep power-cycling the console until you manage to get the state you want?
Odds aren't relavent. If it's possible, then it's possible.
The way RAM works, there is a pattern to initialization, some bits will always mirror or oppose the same other bits at each initialization time. You don't need to prove the state in question happened in one in a million power ups, you need to show the lines in the RAM is connected in such a way that the state you've chosen doesn't violate any of the relationships that require mirror and opposition between all the bits in the state.
Edit:
Alternatively, you can show that the game in question after decompiling it (or similar) only happens to look at the bits in question that you're setting, so we can ignore researching the others bits. Then you simply need to prove the validity of the state of the bits you're setting in their relationships to each other and their ability to be 0 or 1 randomly.

Don't be sure of anything, thanks to bit propagation there are more invalid states than there are valid ones (mathematical proof and elaboration). People seem to be utterly clueless on this point.
