Awesome video!! I’m a huge EXR fan. I did not know about the EXR viewer program though, so thank you!

VFX pros tend to forget that something that's common knowledge for us may not be widely known or understood. Thanks for enlightening the community.

This was a knowledge void that somebody had to fill. Thank you for making it. I look forward to watching it thoroughly.

cool! Now is time for an AGX workflow tutorial

DWAA is the same compression that is used in JPEG. The trouble of JPEG mostly comes from the fact that each time you save it the information is lost, and if you only save the DWAA EXR once, you only lose it once, that’s why it’s not very noticeable, however… However, lossy compression ideally should be used only to backup the final version of the file at the end of the pipeline, and it’s better to use lossless for all intermediary transformations. - for images without grain: ZIP for 32-bit or PXR24 for 16-bit gives the best results - for images with grain, PIZ - for stereo images, ZIP - for solid color images, RLE (There’s an article called Understanding EXR Data Compression which contains this information)

The file size was the main thing stopping me from changing to EXR. I suppose is time for some changes in my workflow 🙃

this is pure gold. Thanks!

The information this guy is providing us through his tutorials is just a crazy amount of knowledge and really imp stuffs to learn! Also, the intro, outro, thumbnail of his every video is just so amazing, it just makes me fall in love with the tutorial! Thank you for doing all this hardwork for us! ♥️♥️

What a "nice" easter egg at 14:02 :) Thank you very much for this walkthrough. EXR is a beast!

You've literally solved all my issues with EXR, which I had to discard a while ago. Like, seriously, THANK YOU

That level of dedication (using animations for the sections of the Video) is outstanding. Keep up the great content and happy holidays :)

small jpg good for my small brain ... but maybe I will try .. great video :)

Happy to see that somebody finally explained proper Blender - EXR - Davinci workflow to the rest of the world. Great job!

OMG literally the DWAA advice flipped my world upside down. As someone for whom file sizes are a big deal, I never used EXR because of how massive they are, and what an enormous RAM hit big files take on editing software, but DWAA actually being *SMALLER* than PNG?? I never knew this!

OMG thank you, everywhere i read people talking about EXR, they just said they don't use it because of the file size. And now you just went and showed us that actually EXR can have a smaller file size than PNG. Good thing i participated in that poll ( i am one of the basic PNG user.... :D ) + how much more information EXR holds than PNG.

Yes! Thank you so much for this! The last couple of months I've dived deep into Davinci Resolve but there's almost no info on how to correctly grade CG footage if it's not through very complicated VFX comping which I do not do - this was exactly the kind of video I needed! I would love to see more of your grading workflow if you have any tips and tricks, developing different looks etc :)

I've been using Blender since high school, currently a college student and still using Blender for my Senior animation project. I never heard of OpenEXR format, always rendered in PNG or MP4 format. This is really new to me, it looks like somehow it keeps the data of the fire and not effecting the rest of the image? Never even knew this is a thing until KZfaq recommended me this video. I don't know much about video editing, just basic putting clips and sounds together, but this looks interesting. Thanks for sharing, and I'm thinking maybe I should dive into learning video editing to help improve my animation shots.

Nice video!!, but there's a bit of an oversimplification of the role bit depth and file formats play in the data that you're storing. The only reason that your PNG format was clamping and not retaining the exposure is because it was set to 8bit while your EXR was set to 32. Both of this formats can handle 16 bit (way more than enough for anything you might want to do on a render, unless you need to work with data passes), which means that you can use png instead of exr. BUT, of course, exr has advantages, like multichannels, ability to go to 32bit, compressions that are optimized for VFX softwares, created for linear workflows. For 3D renders it should be the standard, and while you can bake the luts in the exr too to make them view as the PNG, it breaks the point as EXR is intended to be used in a linear workflow so that you can use math operations that are valid with what you do. Reason why the EXR ends up looking darker. I would not suggest to use a lossy compression at 32 bit on an EXR file, if you can keep it at 16 instead, still fit all the data you need, and use RLE as a compression. 16bit is still a lot for this case, using position passes or deep passes will need 32bit to avoid "loosing numbers" in there, but for renders and most AOVs you are good with 16, which will size at half of the 32bit already. Lossy compression, you don't notice, until you do :) even more if the idea is to do color operations afterwards.

Didn’t know about djv, thanks for that one :)

DID ANYONE NOTICED?..AT 14:02 THE MOUSE CURSOR WITH SELECTED/HIGHLIGHTED REGION WAS EDITED WITH THE WORD "NICE"...😳😳🤯.THAT'S AMAZING DUDE!

This is awesome! I've always avoided EXR because of huge file sizes. Now I can have extra control over my renders for free! Downloading Davinci Resolve right now, thank you for sharing this.

I didn't know EXR existed until this tutorial and I've realized I was missing out ............thanks alot love ur tutorials very informative ❤

I love how simple you made this for people to understand! I think the second half of getting filmic in Resolve is interesting, but not really required at all, since once you're in there, you might as well use the aces workflow and built in LUTs, no real need to import third party LUTs since you'll always want to apply further grading to it anyway to help it feel more real & ideally to stand out and feel different than 'filmic'.

Everything in your VFX pipeline should be rendered in EXR. Can’t wait for you to do a tutorial on ACES color space

Really, thank you for shedding light on stuff like this. There are so many settings in Blender and tutorials I've watched that gloss over things like this and say 'Use this setting but don't worry about how/why it's used'.

hands down the best blender channel out there, and I've been saying this since I saw your stuff years ago. You keep raising the bar!

A lot of things that were missed about the advantage of EXR is that if you do lots of passes into the EXR, like Ambient Occlusion, Specularity, Diffusion, etc..., then you can readjust those particular layers in the EXR without having to fully render the whole scene again. Makes it a lot easier to work when needing to mix and match different things, like CG with live-action.

For some reason the Blender 3.3 and 3.4.1 OCIO isn't compatible with DJV on my system. This is a great help though! Thanks for doing this work and sharing with us! Such a time saver.

Shoutout to everybody who puts out Blender tutorials, but something about your format inspires me. Thank you for this one!

Usually the Tutorial videos on KZfaq are full of boring waste time stuff that we have to skip most of the timeline to get to the point. But your videos are so perfect that there are no boring parts!!

Hey Polyfjord! Love your Tutorials! Any chance you could do an in depth tutorial on merging cg elements with real live footage shot in log (like s-log or n-log) with davinci resolve?

Just FYI: For animation you can use 16-bit half float instead of 32-bit and save a lot of storage space. You get the same benefits with a negotiable loss of precision. 32 bit is really only needed for displacement maps AFAIK.

I've been looking at Davinci for a while but I was always intimidated. I followed your video and I feel like I have walked into another world! This is exactly what I was looking for and you explained it beautifully. Thank you so much!

This is like the 8th video I watch from you. Congrats, your presentation style n delivery is amazing!

Great tutorial! I'm wondering why you didn't use ACES, since Da Vinci Resolve has full support and you don't need to mess around with filmic LUTs

Very good tutorial! And just some extra note for anyone who sees this comment: combining the EXR with ACES is also a very useful workflow too. And the ACES support in Davinci Resolve really beats AE.

for a generalist blender 3d artist your content is always pure gold. Thank you so much for your work, sir!

Love how informative and still interesting your videos are. I never knew what I was missing out on by skipping over exr. Thank you-definitely going to start using them when I can!

This is great and really thorough. I struggled with getting Filmic to work properly in Resolve and Nuke for a while and eventually settled on using ACES to maintain color consistency. ACES makes it much simpler but is of course not right for every project.

Any idea how to do the same with the new blender 4.0 agx setup?

The quality of these tutorials is getting always so much better...and i like it!

I am yet again floored by the production quality.

I'll stick to my JPG to BMP to JPG to .PDF to .M4A to JPG

This file format also works with GIMP for still image editing.

Your enthusiasm for these programs and tools make me interested in getting back into 3d work again. It has been a couple for years though so I would have to learn it again but it would be so much fun.

The amount of information is just amazing! All your tutorials are epic! Thank you so much! You sir, won the Internet today.

this is gamechanging for me, thank you so much for making this! Do you have any knowledge on how exr performs in after effets?

I accidentally exported a small Blend project in exr. Ran into this video and now I am a convert. Subscribed!

One of my developments for 2022 is to learn Resolve, and I think going forward to break way from using PNG sequences entirely, is to use EXR. But would you say that I should EXR for all my renders? or is it like for particular scenes that have a lot of bright exposure like flames or bloom effects?

I love how excited you are about this. It’s contagious

Beautiful Video. I haven't watched a tutorial this long and been this engaged in a long time so props to you! I got into Blender in December and I've been trying to figure out how to get better each month and now picking up Da Vinci Resolve and seeing this workflow I'm excited for whats to come :-)

PNG can capture this (you call it "exposure") data as well, but the image format needs to support far more than just 8 bits per color channel, and 8bpc is what most tools default to if you are using PNG. Fortunately, PNG supports up to 64 bits per channel. OpenEXR only supports up to 32 bits per channel (32 is plenty, don't mistake what I'm saying). So there's freedom to use either format if color depth and dynamic range are concerns for you, you just need to make sure that your tools know what you are trying to do. OpenEXR makes that easier, because tooling often assumes that the user is a professional and wants professional color depth and so on if OpenEXR is used, and only professional-level tools support OpenEXR (more or less). So, if you use OpenEXR, you're telling the software that you're working in a certain way, and PNG assumes another way of working that isn't readily usable for HDR imagery. So, it's not so much a failure of PNG, but of the way it's normally used (web imagery). PNG supports more color depth per channel than EXR, but PNG tooling is mostly lackluster in my experience, compared to OpenEXR. So, the OpenEXR ecosystem is maturing very rapidly, and it seems to be getting tool authors to make the right choices when it comes to defaults for color depth and grading and LUTs and all of those things.

I always used EXR. I do product renders in blender, these EXR has so much information. BUT the problem I am facing everytime is when I open EXR in photoshop, the render is very high in exposure. Do I have to use an Exposure adjustment to bring it down all the time ? Render looks extremely good in viewport and composite but whenever opened in photoshop it's blown out wit exposure in all the bright places. Is there any fix for it ?

this is what i like to call "Una joyita" thanks for sharing

I'll say that some of my "down the road" projects were going to run into the problem you are detailing here, and I'm super excited to get used to this workflow early! I've used at least two of your tutorials so far, and because of it made a joke animation for a friend who I feel needed a good laugh. Keep being open with your discoveries and how many down/up sides they have. It is why I keep looking trough your stuff to get better workflows, ideas, and just learn new tricks.

hey, am I the only one getting this error message when trying to load the "OCIO" config color space file into DJV? Can anyone help me out? ERROR: Error: Loading the OCIO profile 'C:\Program Files\Blender Foundation\Blender 3.6\3.6\datafiles\colormanagement\config.ocio' failed. Unsupported transform type ! in OCIO profile.

Man!!! Thanks A LOT for all these videos you are posting here. They ARE PURE GOLD!!!

i really enjoy how enthusiastic you are about everything in this video :) and thank you for all the information! this is super helpful

I don’t know why i’m getting all this quality content for free. Man you’re a Legend!

I don't know anything about most of this, but you're still interesting enough for me to have watched half of the video before I event realized it. Great stuff, can't wait to see more

EXR is like Raw files of Photography. In photography, we have Raw files which contain all Camera sensor data without losing any data so you can edit in a software layer. Theres also Raw Videos too but that one is too expensive. EXR files looks exactly the same. I can really just render it rightaway and handle the post processing on other software instead of adjust it to the so-limited tools inside blender! Glad I found this when I'm just starting to learn rendering in blender.

Your tutorials are always useful. Learning about stuff I never knew about

Looks like I’ll be using exr from now on. That compression method is the biggest revelation in this video.

I only started using this format a few weeks ago. Cannot believe how helpful it is.

This is probably the only tutorial I've been able to fully watch! Subbed.

Amazing video! As a total beginner I'm so happy that the algorithm is recommending good habit forming tutorials 😀

I love your videos. Thank you for every single one of them. Looking forward to many more knowledge-bombs. Merry Christmas!

Love the way you say 'amazing!'

Your channel is an absolute gem.

Idk why I’m here, I don’t 3d model or edit renders… but I still am captivated and watch your videos all the way through. Bra jobbat!

Awesome video! So much knowledge in under 15 mins. Really enjoyed your presentation. The bit about DJV is huge - I'm installing it right now!

Every one of your videos is such an incredible wealth of knowledge!!! Thank you!

Never understood what is so great about EXR... now I do! Thanks for excellent explanation.

Man, you are great! I love this kind of tutorials. Tutorials which showing me something new, about questions not explaining by the others ).

I always watch your videos and think "Oh yeah. Polyfjord. That dude does great work" and then it's like "Oh holy *!*! he rendered the transitions!"

Very well explained, and I had been struggling to get filmic into Resolve. Thanks!

You filled a really important gap. Thank you so much!

I was in awe the whole video. Thank you so much for this amazing (color) info!!

I really like your videos, they are not your basic tutorials, there is a lot of advanced stuff and work progress

Thank you very much for the advice. I used to save the normal maps in EXR format (many problems in PNG), but without any compression, now using the compression you suggested I can save them in higher resolution without any noticeable loss in minimal space files.

I love your Tutorial's! You are amazing! Thanks for this!

I never knew about EXR, im blown away.

I am a big fan, you know what you are doing and you explain these stuff clearly. Thank youuuu!!!!!

I didn't know about EXR and this is amazing. Thanks for sharing knowledge.

That's excellent stuff bro, very smart man..... Thanks heaps for putting in the time to share this with us. Subscribed boom!

YES!!! IVE BEEN WAITING FOR THIS!!!! ♥♥♥♥ Thank you! 🙏

I was literally just looking this up today, you're some sort of mind reading wizard. Thank you so much for this I really appreciate it.

Great video! Every tutorial is super useful of yours.

Thanks for sharing this. I'm already an EXR adopter but knowing about this compression method is huge. Thanks.

Thanks for this! I always love knowing methods outside of what is default.

I had to search for and come back to this tutorial. Life-saver :)

thank you for all this amazing workflow. I am totally in now.

Yout knowledge and presentation is awesome. Glad to see your videos.

Oh wow, that example was amazing!

mamma mia, this is something I was pondering about last weeks explained in totally simple way

Lovely video, gonna start using EXR!

It is incredable. I so gratefule for your tutorial. I will share it everywhere.

Thank you so so soooo much for this! I struggled so hard with exr and how to compose it. You really are the GOAT!

i always do a stupid amount of post for my animations and renders. ive never heard of exr format before.. this vid completely changed my workflow and if it isnt too dramatic, my life. oh my god i love you.

Thanks a lot for this. Excellent workflow and the tutorial was structered perfectly!
