While the Encord platform is able to handle large volumes of data, we strongly recommend working within the following limits to ensure smooth operations and limit loading times.
Please see our Supported data page for detailed information for all supported data and file types, as well as addressing any data related issues such as long buffering times
The limits outlined below apply whether you're using the SDK, or the web-app.
|Maximum number of data units||5,000||2,500||1000|
|Maximum image/video/DICOM file size||1 GB||1 GB||500 MB|
|Maximum JSON file size||100 MB||100 MB||10 MB|
|Label row / Annotation task limit||50 MB||50 MB||10 MB|
|Model predictions import limit||50 MB||50 MB||10 MB|
|Maximum resolution||4K (3840 x 2160 px)||4K (3840 x 2160 px)||4K (3840 x 2160 px)|
|Number of frames per video||200,000 (2hrs at 30fps)||200,000 (2hrs at 30fps)||200,000 (2hrs at 30fps)|
When a project is too large, the files in the attached dataset(s) need to be resized, as shown below.
Learn how to resize your videos here.
|Maximum number of projects||Unlimited||Unlimited||10|
|Maximum dataset size per project||100 GB||100 GB||100 GB|
|Maximum number of labels per project||1,000,000||1,000,000||1,000,000|
|Maximum number of instances per project||10,000||5,000||5,000|
|Maximum number of tasks per project||5,000||2,500||1,000|
|Maximum number of images||500,000||50,000||50,000|
|Maximum number of users||Unlimited||Unlimited||1|
Even if you stay within these limits, we recommend to create a new project every 6 months and archive the existing project
Encord isn't supported on small screens such as tablets. The minimum application window resolution needs to be 800x600px.
We strongly encourage the use of Chromium-based browsers (e.g. Google Chrome, Brave, Edge) when using Encord. Our team conducts all development & testing using Google Chrome.
This is primarily due to optimizing performance & ensuring data integrity. Modern browsers give no control over deterministically rendering media files (e.g., displaying frames and rendering videos). Further, we also recommend turning off hardware acceleration in Chrome.
Hardware acceleration adds another layer of uncertainty to video rendering in the browser. To eliminate unexpected behavior, we strongly recommend disabling hardware acceleration.
If you have any questions on the above or are experiencing performance issues please contact us at [email protected]
We support a range of formats and codecs. For optimized performance we recommend using the following video formats:
- .mp4 file with h.264
- .mp4 with vp9
Please ensure that videos have a constant frame rate and no audio tracks. The label editor will inform you when we detect audio present in the video files. You can remove audio tracks in videos already in the Encord platform by using the media re-encoding feature in our platform, detailed here.
The platform supports a range of image formats. For most cases we recommend to use:
For more information please see the relevant section in our documentation.
The resolution of any videos and images should be limited to 4k pixels (3840 x 2160 px) to avoid issues. If you have other requirements, please contact us first and we will help evaluate suitability for specific use-cases.
Be sure to check out all the keyboard shortcuts available when using the label editor, to help speed up your annotations!
