In terms of gif "quality" - do you mean resolution or something else? Disabling the post processing

In terms of gif "quality" - do you mean resolution or something else? Disabling the post processing was mentioned before. That appears to have been accidentally reenabled and would hit gif quality quite badly in some cases

Zandy•11/7/21, 1:44 PM

Will definitely give it a try @andybak !

andybakOP•11/7/21, 1:48 PM

@AncientWorlds I wish we could pin down exactly when gif quality degraded. Was it bad in the first Open Brush release? Is it bad in Multibrush? I can't see what would have changed

andybakOP•11/7/21, 1:49 PM

You said it was fine when you compared with the last Tilt Brush release. I wonder if it was already broken in the initial open source version

mikesky•11/7/21, 2:08 PM

The gif stuff wasn’t in the initial open sourcing, we had a PR put in for it using another open source library

mikesky•11/7/21, 2:08 PM

So it may not be the original library used in tilt brush

andybakOP•11/7/21, 2:16 PM

ah! that's helpful

andybakOP•11/7/21, 2:22 PM

So - I want to know if it is related to post processing or not. @AncientWorlds - are you pretty certain that Tilt Brush gifs had no bloom etc?

andybakOP•11/7/21, 2:28 PM

Can you try one other thing for me? In Scripts/Gif Creation/GifEncodeTask.cs line 166 - change:

and see if it makes a difference to the gif quality?

andybakOP•11/7/21, 2:29 PM

Seems like every frame is being forced to use the color palette of the first frame and in some cases this might be unsuitable. Might not be the biggest factor though. Depends how typical the first frame is

andybakOP•11/7/21, 2:35 PM

There's also a quality setting that ranges between 1 and 30. It defaults to 10. If you add the line:

ge.quality = 30;

it should change that. I'm not entirely sure if lower=better but try 1 and 30 and it should be fairly obvious

NLR•11/7/21, 6:35 PM

Gifs are pretty laggy, the motion is not smooth (especially for the 5 seconds gif).

punktvr•11/7/21, 6:46 PM

Hello wonderful Icosa people. I remember seeing talks about taking out the lens blur from video recordings a long time ago- could someone direct me on where i can find more info about that?

Aandybak Sorry - I don't have my headset with me at the moment and I want to check before...

Karmen Olmo•11/7/21, 9:22 PM

First thanks for your support and sorry i see it late. Yes i want to maje a movie navigating the piece. To place some music over. Like you said fly over the work. On mac only gif and picture. Nothing else. Like when use Oculus alone.

AncientWorlds•11/8/21, 8:31 AM

Really good info, will take a look at the tools and changes.
How should I have post processing set in the openbrush.cfg file, for this purpose?
As to when it began, probably when the gif file change was made initially.
The newer version does seem to introduce artifacts fairly often, and I'd definitely prefer overall quality improvements.
I considered resizing the video recorder tool window (the square frame is easier to navigate for some shots), but that isn't really the desired outcome.
Anyhow, appreciate the info.
Curious what the other two modes do

andybakOP•11/8/21, 9:49 AM

Trying to understand what "laggy" means. Low frame rate?

andybakOP•11/8/21, 9:52 AM

The "frameDelay" setting for each preset in my earlier screengrabs seems to control frame rate. It's set to 0.05 which 20fps. I do wonder though if gifs are really the right format if you want higher quality. Why not video? Gifs are essentially just a weird historical relic and should probably have been put out to pasture 20 years ago

AncientWorlds•11/8/21, 9:54 AM

two reasons gifs are nice: Easy to post to social media. Square camera format is easy to walthrough navigate scenes with

andybakOP•11/8/21, 9:55 AM

You can have square video too.

andybakOP•11/8/21, 9:55 AM

What social media accepts gif but not video? (Twitter's horrible video compression aside)

andybakOP•11/8/21, 9:55 AM

Or is it about gifs being accepted in comments where videos are only in main posts? I don't do a ton of social media so I'm probably missing some subtlety here.

Aandybak Trying to understand what "laggy" means. Low frame rate?

NLR•11/8/21, 10:09 AM

Not sure if the lag is due to frame rate or the capture itself

NLR•11/8/21, 10:10 AM

Yeah I need GIFs cause I sell NFTs

NLR•11/8/21, 10:10 AM

But I agree GIF sucks ^^

AncientWorlds•11/8/21, 10:11 AM

Gifs autoplay on some of them, video has to be activated. Generally easier to use.
Now facebook changed their display format so the ones from open brush are actually huge (about the same size as the videos)
Haven't tried making a square video yet, and not sure how the reformat algos would handle it.
Generally gifs fit better in feeds. What is most usable depends on the social media account.
I got some tips on disabling audio in video, but it's still more work to produce and review them

NNLR Yeah I need GIFs cause I sell NFTs

andybakOP•11/8/21, 10:14 AM

NFTs can't be mp4 video? I thought they were basically just a url.

NLR•11/8/21, 10:15 AM

The problem is that video do not autoplay on opensea:
https://opensea.io/collection/metaverse--wearables

BTW get yourself some openbrush-made NFT goodness ^^

andybakOP•11/8/21, 10:16 AM

video do not autoplay

They should fix that. Autoplay should be off by default if there's audio (or at least muted) but on by default in most other cases. I've actually got a Firefox plugin that turns off autoplay for everything but then I'm weird.

NLR•11/8/21, 10:17 AM

I agree

andybakOP•11/8/21, 10:17 AM

"Let's use a crappy 30 year old format because there's this one website that won't change 1 line of code"

AncientWorlds•11/8/21, 10:18 AM

Gifs are built for sharing, memes are at least half the internet now

andybakOP•11/8/21, 10:18 AM

(and I checked - animation was added to the gif in the 1989 standard. So happy 30 year anniversary animated gifs!)

andybakOP•11/8/21, 10:19 AM

Gifs are built for sharing,

no. gifs are used for sharing because of a cluster of poor usability decisions by browser vendors and web developers.

mikesky•11/8/21, 10:20 AM

Video has come a long way since the social media age, and is miles more efficient and better looking than you could hope to achieve with gifs. It's a shame it's treated like a secondary format by the platforms still

mikesky•11/8/21, 10:21 AM

AncientWorlds•11/8/21, 10:23 AM

Ya, it is. I assume it's entirely a bandwidth decision. Also the last rugged remnants of traditionalism
Anyhow, they tend to fit box-like column formats well.
Inside open brush they are currently easier to use, in general, even if not quite as sharp.
No reprocessing, can quickly open a bunch in browser tabs, easier to frame shots

Aandybak heh. anyone remember the gif patent boycott?

andybakOP•11/8/21, 10:24 AM

gifs are bigger than the equivalent video file unless you're doing something very weird with your compression settings (or doing pixel art)

AncientWorlds•11/8/21, 10:24 AM

Also, can add them in the background without much overhead, which is something I've been thinking about a lot, though haven't used much
transparency would open up some interesting options

AncientWorlds•11/8/21, 10:25 AM

I've got a project planned which will probably use a lot of them, just haven't got to it

AncientWorlds•11/8/21, 10:26 AM

filming video on video didn't work well, iirc. also the gifs fit into box frames better

andybakOP•11/8/21, 10:27 AM

In terms of concrete feature changes from this - can i summarise?

Someone will hopefully play with the gif presets inside Unity and suggest some new presets
If I get feedback about the quality setting, then I will tweak that
Still need to pin down whether quality issues is related to post-processing or not.
I'm considering adding user presets to the config file so allow people to define their own gif presets.

andybakOP•11/8/21, 10:28 AM

That "box" thing again. Is it not possible to make square videos?

andybakOP•11/8/21, 10:29 AM

I'd really appreciate improvements to the docs around video, gif and image export. I don't use it enough. You lot use it all the time - you can do a much better job of documenting it than I could.

andybakOP•11/8/21, 10:30 AM

Current user submissions to the docs is hovering around 0

AncientWorlds•11/8/21, 10:32 AM

@andybak
Presumably, but then I have to step out, change the files.
Also also not sure about recording recordings, my computer didn't do well the one time I tried, but may have been updating, not sure.
As far as documenting, don't really have anything to add to what's in the original tilt brush documentation
I usually just hit the camera button and push record, haven't experimented a lot with it. Haven't done paths for a while.
As far as export, just goes in the documents/open brush/snapshots folder (or video) and grab it from there
If there was a square panel preset for video I'd probably use it.
Presumably most people don't shut off animations in their browser, and if it's an extra click you'll lose half your audience if its in a place like twitter

Mmikesky webm and webp are :chefkiss:

NLR•11/8/21, 10:32 AM

oh yeah webm might have autoplay let me check

andybakOP•11/8/21, 10:35 AM

I know some sites were autoconverting gifs to autoplay webm to cut their bandwidth bills.

andybakOP•11/8/21, 10:36 AM

https://developer.chrome.com/blog/autoplay/

andybakOP•11/8/21, 10:36 AM

Chrome's autoplay policies are simple:

Muted autoplay is always allowed.
Autoplay with sound is allowed if:
The user has interacted with the domain (click, tap, etc.).
On desktop, the user's Media Engagement Index threshold has been crossed, meaning the user has previously played video with sound.
The user has added the site to their home screen on mobile or installed the PWA on desktop.
