For example, zoom out by 1 time at 1 second and zoom in by 2 times at 5 seconds; then the time points of 1 second and 5 seconds are called 2 key frames.

SDK independence1. The API and the interface code provided by our upper layer are completely independent, and various interfaces can be customized and can be changed in a wide range;
2. You can even develop an interface that meets your actual needs independently without our interface;
3. Various API interface specifications, 90% of APIs are written with get/set specifications.
Frequently Asked Questions
  1. What is the difference between Standard Edition and Ultimate Edition?
      Ultimate version support: Picture-in-picture/key frame/MG transition/special effects
  2. Does the SDK collect user information?
      Our SDK does not access the network, and will not execute function-independent code. You will execute it if you call it, and it will not execute if you do not call it.
  3. How much freedom is there, can I customize the interface?
      The SDK and the interface are completely independent. The interface source code will be made public. You can add your code to our interface code. You can also develop your own flexibly without our interface
      SDK is provided in the form of a module, (android is an independent module, ios is an independent framework)
      The upgrade can directly overwrite the previous folder. It has no effect on other codes.
  4. How scalable is the SDK?
      All the materials are externally input in the form of paths, and each additional layer is a layer of pictures, and various independent operations can be flexibly performed on each layer.
      Various materials can be laid out up and down, left and right, front and rear masks, and even you can make various configuration files to configure the materials with one click.
      At the same time, various callbacks are exported, so that you can export various parameters during processing for further processing.
      The SDK is provided in the form of classes, which can inherit our classes for further algorithm extensions, such as filter algorithms, etc.;
      The architecture version also leads to layers and sublayers and drawing classes, allowing you to freely draw some algorithm effects;
  5. Can we make various materials ourselves?
      Yes. What we provide is video synthesis technology, all the materials can be made by yourself. We provide production documents and demonstration videos detailing how to make the materials.
      Materials include stickers, gif, animation, json animation, transition animation, special effect animation, etc.;
  6. Do you have a server, do you put the produced materials on your server?
      We don't have a server, you need to manage all kinds of materials yourself. SDK does not care about the source of the materials, just set the material path.
  7. What is the form of technical support?
      We provide QQ, WeChat, DingTalk, phone, Skype, WhatsApp, email instant messaging tools for docking, and direct communication if there is a problem.
  8. What do you provide for the architecture version of the SDK, and what functions can it do?
      The architecture version of the SDK is to bring out our internal layer architecture API, mainly sublayer classes, background execution classes, and drawing classes.
      For example, Android leads to the Canvas layer, then after you get the Canvas layer, you can draw various specific functions at will. Lead opengles objects to draw various gl textures.
      The background container is open, and you can synthesize materials freely to achieve your specific functions.
      The architecture version of the SDK is suitable for applications with video as the core, and customers who have their own ideas and constantly launch new features. Or customers in specific video editing occasions.
  9. Can I only use the functions in your demo app?
      No. The functions in the demo app are just commonly used function demonstrations. From a technical point of view, every time you add a material, an LSOLayer object will be returned.
      All materials are LSOLayer objects. What are the functions of LSOLayer objects, video support, pictures/motion pictures/transparency animation, and the same support.
      We just put some functions on the video, and some functions on the picture; but in fact, they are the same, and most of the functions in the LSOLayer object can be used.
      After you understand this, you can freely combine different materials.
