YoshL's Quick "Find Your Offset" Tutorial
 

For those of you who feel like arrows are coming too soon or too late, or feel like there's some sync issues at hand.
This can be kinda seen when you're playing a file and you have an abnormal Perfect to Amazing ratio (with some random goods/other PA), where it feels abnormally high (for me, when i hit something around 1:2 perfects to amazings ratio, i feel like it's a little necessary to adjust offset).

There's a fairly easy way to fix it. Just remember that you have to have a framerate of (probably) 60 or 120 etc. or something for this to work relatively well. *(unconfirmed)

================================================

Step 1: select a part of the song that's very easy to get good accuracy well, but isn't slow. Usually this is a constant rhythm that you can tap, not single notes with large gaps in between. You don't want hard sections for this

-------------------------------------

I'm going to pick "System Doctor" as an example.
I don't want to select the intro to the song because the notes are spaced way too far apart, and thus will result in you visually watching the arrows to the receptor, rather than relying on rhythmical accuracy.
I don't want to select the ending of the song because there's nasty 32nd bursts that pretty much require mashing, or non-optimal accuracy to hit properly.
I do want to pick some of the 8th note sections that are really easy to hit with good accuracy, thus i'm going to start isolating at note 510 as my section.

================================================

Step 2: isolate said part (it's up to you how long you want to hold the section with good accuracy), and concentrate very hard on using only the audio for timing. If need be, try covering up the receptors in order to do this well.


as soon as you're done with the section, you want to quit out of it. As you can see, I still AAAed the section in question, however the accuracy seems a little bit off.

================================================

Step 3: right click the speed mod in order to get the "base offset" as I'll call it


In my case, my accuracy was -.350 ms with a variation of .452 ms in either direction. The "base offset" would be -.350 ms. You can repeat this to get a better understanding of where your hits are centered. Longer sections of file that you hit will result in (probably) a more accurate offset.

================================================

From here, you have 2 choices. Usually you would start with Choice 1, but if you find the base offset to be very similar regardless of what you set the global offset to, then probably choice 2 is the backup case.

Choice 1: modify global offset (visual positioning)
if you feel like the notes need to be shifted in respect to the music, in your options menu, go to your global offset, and set the value to the negative sign of your "base offset"


because my "base offset" was -.35, i want .35 as my global offset.

If you already are using a global offset, add the negative base offset to your current global offset.

================================================

Choice 2: modify judge offset (judgement positioning)
if you feel like the arrows are perfectly aligned with the receptors, or have been fiddling with global offset without finding any positive effects, then you'll probably have to mess with judge offset.
Simply plug the "base offset" into the judge offset box.

note: only use either choice 1 or choice 2 after a sync test. you can combine the choices, however when applying your base offset that you've found, only apply to 1. (or balance out the offsets, but this is probably not something you need to be worrying about)

and that's pretty much it. Again, i usually default to choice 1 because it just works better for me


and my accuracy skyrockets after fixing offset


please also keep in mind that you'll probably have a general "global offset" that you'll hover around, but many songs are off by like .3 in either direction, some go waaaay beyond and require a little more tuning to get. A lot of the time, the offset delta will be like .1 and fairly negligable, however to more sensitive players it may still be a problem. With FFR's limitations, the need for these offsets arise unfortunately, however this is a workaround that doesn't take too much time, and honestly is 100% worth it in the end in terms of nailing out those extra-tasty scores.

Happy arrow smashing!

then yosh follows his own guide and gets promo'd to d7. yea guys this thing is super effective.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Will test thoroughly today with progressive pics

Re: YoshL's Quick "Find Your Offset" Tutorial
 

world of dreams, iso beginning at 401, and masked accuracy worked really well for me ^^

Re: YoshL's Quick "Find Your Offset" Tutorial
 

also take note that again, sometimes if you check your accuracy after a full song play, there may be sections of the song *(usually harder sections) that you might tend to hit earlier, or later than you'd normally hit just because of the difficulty. so while the final accuracy of a full playthrough might represent the actual accuracy that you hit throughout the song, it won't properly represent your true accuracy. instead of fixing your offset here, you would need to fix your playing (i.e. figure out whether you need to envision yourself rushing forwards or lagging behind on patterns/sections)

Adding a link/reference for this thread to the ATTN: Velocity Players thread.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

This is definitely where I always had a problem. I would play something like Yoshi Cookie, and find the offset, but when I played (insert longer, harder files) I feel I would do trash, and thus think the offset I have is completely off due to way to many goods to perf/amz

Re: YoshL's Quick "Find Your Offset" Tutorial
 

unless your perf/amazing ratio is off, if you're hitting a lot of goods, then it's just you playing bad, or bad lag

Re: YoshL's Quick "Find Your Offset" Tutorial
 

A lot of the time my p/a was about 1.1 somtimes, 1.2

i'd say it's about 1.3-ish now after doing this. still get goods, but much lower, and i know thats just due to my decrease in skill and probably just my laptop

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Is there going to be a quick tutorial on how to fix lag? :)

Re: YoshL's Quick "Find Your Offset" Tutorial
 

YoshL's quick tutorial on how to fix lag

Re: YoshL's Quick "Find Your Offset" Tutorial
 

That tutorial actually helped! Wow, YoshL got mad help skills. 10/10

Re: YoshL's Quick "Find Your Offset" Tutorial
 

sonf a dink

Re: YoshL's Quick "Find Your Offset" Tutorial
 

I'm gonna use that right now yoshl, thanks

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Well this fixed my accuracy problems, now if I could ever make it stop lagging it would be usable -_- I've tried a million things and every guide I can find and nothing ever works. It's really the only reason why I still use Velocity. At least that never lags on me =/

Thanks for the guide though, made it feel a lot better. One step at a time.

EDIT: I take that back. Figured out how to fix the lag by running fullscreen, but then I get these weird looking scanline type things that make it really hard to read. Almost there...

Re: YoshL's Quick "Find Your Offset" Tutorial
 

UMMMMM...HOLY SHIT!!! O.o MASSIVE thanks YoshL, I thought it was impossible to go for accuracy on a frames based engine. Best on this is 6 Perfects?


So you know I'm not pulling your leg...fuckin' insane eh? I don't claim to be "INSANE WR!!111!" material but this just blew my mind...thanks man.


This tutorial really helped me, now if I could clarify something: is the Global Offset in ms or still in FPS? (based on 30FPS) I ask this so I know what unit = 1ms, so I can use your method, then fine tune the number given so I'm square in the middle of the Amazing window, so getting Perfects would feel like getting Goods haha.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

the global offset is definitely in frames (i think to be 100% accurate, it's frames in 30 fps)

Re: YoshL's Quick "Find Your Offset" Tutorial
 

I definitely need to give this a shot.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Great tutorial, bookmarking for future reference

Re: YoshL's Quick "Find Your Offset" Tutorial
 

so whenever I start my next session, I'm going to begin compiling a google doc of all the standard offsets I use on songs that I normally play, and I think it'd be productive if people also contributed their offsets to the sheet as well. Just as a nice community tool to use to make finding offset easier

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Funnily enough I had the same sort of idea, but I'm not sure if I have the patience to write offsets for all 1993 files in the game (well the ones I'm good enough to unlock anyway, plus some require like ultra grinding to unlock). Only caveat is that different hardware/software setups will reduce these numbers to educated guesses, but you could always take the difference between your offset on song x and their offset on song x, then apply that difference to all of the offsets from that player (same logic with this list, difference between your offsets and the list's offsets). Plus SubjectiveMania (I like mine onbeat/slightly late, some people like it soooo early I have no idea how they get a good score haha, but whatever works for them). One random tip I discovered which gave me a lil' boost in the FPS, for laptop players make sure you go to "Change advanced power settings" and check that Intel Graphics Settings/nVidia etc = Maximum Performance on plugged in/on battery.

Anyway, to chip in a few of mine (no Judge offset just the global @ 60FPS on standalone Flash Player 12, Intel graphics on a Samsung laptop). Bear in mind many are before I discovered your tutorial so I may amend these later for myself:
Dance 1
- Free Space: 1.74 (I've also done well on 2.01, undecided atm)
- Power = 1.83
- A = 2.01
- Syndrome Craze = 1.74
- Fly With Me: 0.99 (balls the syncing on this is terrible)
- Desperation Pandemic Day Mix = 3/3.21 (drifts soooo bad, can't find a good offset for it)
- Back to the Gate: 1.491 (used your tutorial to get it down to 0.005ms difference)

Dance 2
- Air: 2.82
- Vertex Beta: 2.039 (your tutorial)

Misc
- Uber Rave v2 = 3.09?

I started with the tournament files really quickly, just for nice reference. I've used "the stormy song" as a baseline for sync (since I usually drift right around 1.25 in global offset)

If you'd like to contribute, pm me an e-mail and I can give you access to your own column and stuff

as a note, most likely I'd like to add harder spectrum songs onto the list first - easier songs are much more easily timed to visual (legacy songs are almost mandatory to visually time) and doesn't lend to really fixing offset much, and doesn't really matter in the FFR scoring scheme of things

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Thanks, I'll add the easier songs later as it will give me time to sort them by group and difficulty. Can test the tournament files too but I'm terrible at spread LOL.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

just make sure to do the stormy song as a baseline that's all

Re: YoshL's Quick "Find Your Offset" Tutorial
 

I thought the logic was to find YOUR offset for general songs...

Like for example, lets say that no matter the song, you consistently hit the arrows x frames early, so you set offset to a certain amount.

I figured the offset stayed consistent between the songs lol, I always use judge offset, figured it was based on how YOU hit the notes, not the song.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

because of the way files are converted, there's a possibility of error between the actual audio and the frames in the 30 fps file, so different songs get fudged by differently, it's not constant over the whole songlist at all

judge offset is handy if you want your hitposition effectively moved up and down without the arrow to music sync changed. global offset physically shifts the chart so that arrows appear earlier/later

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Ye, I see the difference. I figured changing judge offset was a more personal thing on how you yourself hit the arrows, which is usually how I do it, and I'd use the global for music syncing.

Wouldn't ideally every song just be 0 offset and the songs corrected?

Also, I think I've seen people say they use late offsets on purpose to give them more time to hit fast things, I recall someone saying it regarding a tournament file, unsure how that'd work thought. I've also used offsets to do the tokens where you need to hit averages or whatnot.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Things that are slow enough for you to read well are easy enough to hit accurately even when they are not sync'd with the music, but fast stuff that you react to causes you to be prone to hitting it late or drifting towards later and later hits, meaning if you play those sections with the music you're much more likely to hit accurately with a late offset.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

imo if you're hitting hard sections late, then you need to learn how to hit them on time, not fudge your offset so that it's easier for you in your current speed/reading (also it's usually more of a matter of adjusting the judge offset there).

learn properly, and get better faster

Re: YoshL's Quick "Find Your Offset" Tutorial
 

I play fast jumpstreamy shit with a later offset than everything else cause I'm slow and bad at it
also helps when I start hitting late cause no stamina

Re: YoshL's Quick "Find Your Offset" Tutorial
 

I don't personally use offsets for anything or condone the use of offsets for this purpose, but that's the theory, and it holds in practice.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

so i tried using offsets for the first time since D1 after reading this thread. i proceeded to butcher my accuracy, and now idk how im gonna straighten my performance before the next round lol

Re: YoshL's Quick "Find Your Offset" Tutorial
 

go to bed and wake up and everything will be normal

Re: YoshL's Quick "Find Your Offset" Tutorial
 

oh look, that worked. sweet lol

imma keep from messing with offsets til i get eliminated from tourney.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

That's an interesting idea if you don't have time to git gud (as many people might during this OT)

But YoshL is correct, that is a fudge tactic.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

my offset keeps changing....how do i fix

Re: YoshL's Quick "Find Your Offset" Tutorial
 

when you right clicked on result it showed accurracy. it wont do that for me. im using chrome btw

Re: YoshL's Quick "Find Your Offset" Tutorial
 

What about the auto offset feature? " Auto Calibrates When Exiting A Song With Atleast 50 Notes Hit".

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Auto judge offset was created to automate the steps in this guide for you. :)

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Same. I wonder if that was part of a previous engine build.

Re: YoshL's Quick "Find Your Offset" Tutorial
 

So having auto judge offset is better then manually finding out your offset?

Re: YoshL's Quick "Find Your Offset" Tutorial
 

imagine like.. it was like.. setting your judge offset, but like the name says, auto!! woawww

Re: YoshL's Quick "Find Your Offset" Tutorial
 

Just play without sound; it's all about the arrows anyway.

Re: YoshL's Quick "Find Your Offset" Tutorial

thanks helpd alot
