    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

    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.

  • @GianlucaPizzaia
    @GianlucaPizzaia 2 ปีที่แล้ว +81

    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.

    • @christophott
      @christophott 2 ปีที่แล้ว +11

      ...thats not 100% true.
      the data in the EXR files is stored linear and the data on the PNG is stored witch a color profile baked in (probably sRBG).
      With the color profile baked in you lose precious data.
      I agree that in most cases you can get away with 16 bit EXR files

    • @TangerineTux
      @TangerineTux 11 หลายเดือนก่อน +1

      16-bit PNG does nothing to prevent clamping over 8-bit. It’s still stored as integers where the maximum 16-bit value, i.e. 65535, means the same thing that 255 does in a 8-bit PNG. What you can do in principle is use an encoding like PQ or HLG where that maximum value means something significantly brighter than diffuse white, but support for such PNGs is not great. It will work with either 8- or 16-bit PNG, but 8-bit is likely to exhibit banding due to the lower precision within the (identical) range.
      EXR (whether 16- or 32-bit), in contrast, stores values as floating point numbers which can trivially go above 1.0 (equivalent to PNG’s 255 or 65535).

    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 TH-cam 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.

    • @DiThi
      @DiThi 2 ปีที่แล้ว +14

      PNG (and most image formats) have a limited range, for example from 0 to 255, where the maximum is white, and there's nothing after that. EXR uses floating point, that means the number doesn't really have a maximum value. 0.0 is black, 1.0 is white, but 2.0 is even more white.
      Additionally, most formats use gamma correction (particularly the standard sRGB) to preserve darker tones (which we are much more sensitive to than lighter tones) in just 8 bits per channel, while EXR is typically stored in linear format (no gamma correction at all), because floating point has more precision on small numbers, and because each floating point number typically has at least 16 bits (usually 32).

    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.

      ​@@shamaiahellis8810 I'm not really the expert since I just started using this in less than a year. You can find a lot of posts online about this topic. I guess the main difference for me is I just set Blender to use ACES and export EXR in 32 floats without composition nodes. One promising feature of ACES is its ability to contain all the color spaces and convert to any of them to your need (If I remember it correctly). And also future-proof since it saves really a lot of data outside of ordinary color spaces. Please correct me if I was wrong on anything. Really a newbie here anyway.

    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.

      @damian_madmansnest 2 ปีที่แล้ว +1

      ACEScg is the best!
      I’d rather Blender had (an option) to use ACEScg by default without the necessity to have a separate copy of Blender with replaced colormanagement folder or starting Blender with scripts.

    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.

    • @TangerineTux
      @TangerineTux 11 หลายเดือนก่อน +1

      No, PNG does not support more than 16 bits per channel. Per the PNG specification: “Sample depths range from 1 to 16 bits.”
      It’s also integer-only, not floating point like OpenEXR, and regardless of the bit depth, the maximum integer value still represents the same thing, so increasing bit depth in PNG does nothing to extend the range of representable values, it only increases precision within that range.

    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?

      The only case I’d use PNG is if the rendered file goes directly to the internet. If you plan to do any color correction or compositing to the render, EXR is the best option because it does not burn color space into the pixels and retains all the color information.

    Using EXRs was already workflow standard by the mid 2000s for many VFX houses since it retains the exposure data which allowed for adjusting any bright whites or dark blacks. Not to mention the ability of EXRs to save out and store AoVs. Blender is almost caught up to Maya, Softimage, Max, from 2007 in that regard. I am starting to use it more now that one can adjust the 3d nav controls to be more like Maya. It took it almost 20 years but I am starting to see it used more often than usual finally. With the advent of Redshift available for Blender it really has a nice path to the production houses now.

    Great video. Just one little thing. If you do your color management in Resolve using LUTs, put the LUTs on separate Nodes like explained in the video, but if you do additional grading place those nodes BEFORE the LUTs in the node tree. LUTs should always go last in the tree, because they can potentially clip image data.
