Gợi ý
If you are not interested in technical details, a good rule of thumb for selecting output formats for your project is:
- Sử dụng định dạng OpenEXR
if you intend to do compositing or color grading on these images.
- Sử dụng định dạng PNG
if you intend on-screen output or encoding into multiple video formats.
- Sử dụng định dạng JPEG
for on-screen output where file size is a concern and quality loss is acceptable.
All these formats support compression which can be important when rendering out animations.

Mở hình ảnh
- Đường Dẫn Tương Đối
Sets the file path to be relative to the currently opened blend-file.
See Đường Dẫn Tương Đối.
- Phát Hiện Trình Tự
Automatically looks for image sequences in the selected images (based on the file name). Disable this when you do want to get single images that are part of a sequence.
- Phát Hiện các UDIM
Automatically looks for UDIM tiles in the directory of the selected image; if matches are found they are loaded into Blender as UDIMs. This works by detecting if the filename has a
.xxxx(four digit number) before the file extension.
Mở một Trình Tự hình ảnh
To load image sequence in any of the supported image file formats,
the filename of the images must contain a digit to indicate the frame order
(e.g. *-0001.jpg, *-0002.jpg, *-0003.jpg, etc, of any image format), indicating the frame.
The sequence could be opened by the selection of the images with any of the following methods by the confirmation with the Open Image button or Return.
- Phạm Vi
Navigate into the directory and LMB click and drag over a range of names to highlight multiple files. You can page down and continue Shift-LMB click-dragging to add more to the selection.
- Hàng Loạt
Shift-LMB click selected non-related stills for batch processing; each image will be one frame, in sort order, and can be a mix of file types (
jpg,png,exr, etc.).- Toàn Bộ
Press A to select/deselect all files in the directory.
Lưu các hình ảnh
- Định dạng tập tin
Choose what format to save the image as.
- Chế Độ Màu
Choose the color format to save the image (or video) to. Note that RGBA is not available for all image formats, check the list above for details.
Trắng/Đen, Đỏ, Lục, Lam, Đỏ, Lục, Lam, Alpha
- Độ Sâu của Màu
Some image file formats support a varying number of bits per pixel. This affects the color quality and file size. Commonly used depths:
- Quỹ Đạo -- Orbit
Most common for on-screen graphics and video.
- 10, 12, 16-bit
Used for some formats focusing on photography and digital films (such as DPX and JPEG 2000).
- Số Thực Dấu Phẩy Động 16-bit với Độ Chính Xác Một Nửa
Since full 32bit float is often more than enough precision, half float can save drive space while still providing a high dynamic range.
- 32-Bit Số Thực
Highest quality color depth.
Ghi chú
Internally Blender's image system supports either:
8 bits per channel (4 × 8 bits).
32 bits float per channel (4 × 32 bits) -- using 4 times as much memory.
Images higher than 8 bits per channel will be converted into a float on loading into Blender.
- Nén
Used to reduce the size of the image file. How this is done may vary depending on the file format and settings used.
- Chất Lượng
Similar to Compression but is used for JPEG based file formats. The quality is a percentage, 0% being the maximum amount of compression and 100% is no compression.
- Lưu như Bản Kết Xuất
Applies color transform to the saved image.
- Sao Chép
The Copy checkbox will define if the data-block will reference the newly created file or the reference will be unchanged, maintaining it with the original one.
Chi Tiết về Định Dạng
Cineon & DPX
Cineon is Kodak's standard for film scanning, 10 bits per channel and logarithmic. DPX has been derived from Cineon as the ANSI/SMPTE industry standard. DPX supports 16-bit colors/channels, linear as well as logarithmic. DPX is currently a widely adopted standard used in the film hardware/software industry.
DPX as well as Cineon only stores and converts the "visible" color range of values between 0.0 and 1.0 (as a result of rendering or composite).
OpenEXR
ILM's OpenEXR has become a software industry standard for HDR image files, especially because of its flexible and expandable structure.
An OpenEXR file can store multiple layers and passes. This means OpenEXR images can be loaded into a Compositor keeping render layers and passes intact.
Tùy chọn cho Đầu Ra
Available options for OpenEXR render output are:
- Độ Sâu của Màu
Half saves images in a custom 16 bits per channel floating-point format. This reduces the actual "bit depth" to 10-bit, with a 5-bit power value and 1-bit sign.
Float (Một Nửa), Float (Toàn Phần)
- Bộ Hóa Giải Mã
PXR24Lossy algorithm from Pixar, converting 32-bit floats to 24-bit floats.
ZIPStandard lossless compression using Zlib, operating on 16 scanlines at a time.
PIZLossless wavelet compression. Compresses images with grain well.
RLERun-length encoded, lossless, works well when scanlines have same values.
ZIPSStandard lossless compression using Zlib, operating on a single scanline at a time.
DWAAJPEG-like lossy algorithm from DreamWorks.
- Bộ Nhớ Đệm Z
Save the depth information. In Blender, this now is written in floats too, denoting the exact distance from the camera.
- Duyệt Thảo
On rendering animations (or single frames via command line), Blender saves the same image also as a JPEG, for quick preview or download.
HDR Bức Xạ -- Radiance HDR
Radiance is a suite of tools for lighting simulation. Since Radiance had the first (and for a long time the only) HDR image format, this format is supported by many other software packages.
Radiance .hdr files store colors still in 8 bits per component,
but with an additional (shared) 8-bit exponent value, making it 32 bits per pixel.
