Confirmation "Are you sure?" should result in either instant-post, and save to app library on-device, or save the current video projects as DRAFT to app library on-device

Here's how the confirmation feature and on-device library functionality can be implemented:

Updated Workflow Design

Confirmation Dialog

When the user clicks "POST", display the following options:

  • Instant Post & Save to Library: Posts the video to the selected platforms and saves it locally to the app library.
  • Save as Draft: Saves the video as a draft without posting.

Workflow Steps

  1. Step 1: Create/Record Video

    • The app captures the video using the device's camera.
    • User can preview the video.

  2. Step 2: Configure Post

    • Input post title.
    • Select target platforms (e.g., YouTube, LinkedIn).

  3. Step 3: Confirmation Prompt

    • Show the message:

      "Are you sure?"
      Choose an option:

      • Post Now & Save
      • Save as Draft
      • Cancel

  4. Step 4A: Post Now & Save

    • Upload the video to the selected platforms via APIs.
    • Save the video file and metadata (title, platforms posted, date) to the on-device library.

  5. Step 4B: Save as Draft

    • Save the video and metadata as a draft to the on-device library for editing or posting later.

  6. Step 4C: Cancel

    • Return to the previous screen for further editing.

App Library Features

Library View

  • Drafts Tab:
    • List of videos saved as drafts.
    • Options: Edit, Post Now, or Delete.
  • Posted Tab:
    • List of videos already posted.
    • Shows metadata (title, date, platforms posted).

Functionality:

  1. Edit Draft:

    • Allows users to re-open, rename, or change platform selections for drafts.
    • Post later via the same confirmation workflow.

  2. Re-Post from Library:

    • Users can select previously posted videos to re-share on other platforms.

  3. Local Storage:

    • Videos are stored on-device in a dedicated app directory.
    • Metadata stored in a lightweight database (e.g., SQLite) or as JSON files.

Technical Considerations

Instant Post & Save

  • After a successful upload:
    • Store the video file and its metadata locally.
    • Use unique identifiers to track the post across platforms.

Draft Saving

  • Save the following as a draft:
    • Video file (compressed if needed).
    • Title.
    • Selected platforms.
    • Timestamp.

On-Device Library

  • Create a directory structure:
    /AppLibrary/
      /Drafts/
    - draft1.mp4
    - draft_metadata.json
  /Posted/
    - post1.mp4
    - post_metadata.json

Error Handling

  • Post Failures: If the API upload fails, allow users to retry or save as draft automatically.

Data Security

  • Store files and metadata securely using encryption.
  • Avoid sensitive information like API tokens in metadata.

Next Steps

  1. Update Wireframes:
    • Add the "Library" section to the app’s UI.
    • Design the confirmation prompt with multiple options.
  2. Implement Library Module:
    • Develop file management for drafts and posted videos.
  3. Integrate APIs:
    • Ensure smooth transitions between saving drafts and instant posting.
  4. Test User Flows:
    • Validate the confirmation flow and library functionality.

Need a background remover and replacer so that videos can be created from any location

To include a background remover and replacer for videos in your app, here's how you can approach it:

Core Features

  1. Background Removal:

    • Use AI-based background segmentation to remove the original background of a video.
    • Ensure real-time processing or batch processing for pre-recorded videos.

  2. Background Replacement:

    • Allow users to choose:
      • A solid color (e.g., green screen, black, white).
      • An image (from gallery or app-provided templates).
      • A video (e.g., looping background or dynamic scenery).

  3. Integration with Video Creation Workflow:

    • Integrate seamlessly into the video creation process:
      1. Record or upload video.
      2. Choose to remove and replace the background.
      3. Proceed with posting or saving as draft.

Implementation Options

1. Using Existing Libraries and APIs

  • OpenCV (with Python or Java):

    • Use OpenCV with deep learning models (e.g., U-Net) for segmentation.
    • Strengths: Open-source, highly customizable.
    • Challenges: Requires optimization for mobile devices.

  • TensorFlow Lite / ONNX Models:

    • Pre-trained models for background segmentation.
    • Fast and optimized for mobile.
    • Example: Google's Mediapipe.

  • Commercial SDKs (Plug-and-Play):

    • Remove.bg API (for videos): High-quality background removal for videos.
    • Banuba SDK: Offers AR effects, background replacement, and video editing tools.

2. Native Mobile Frameworks

  • For iOS:
    • Use Apple's Vision framework or ARKit for real-time background segmentation.
  • For Android:
    • Use ML Kit’s segmentation models for background removal.

3. Cloud-Based Processing

  • Offload processing to the cloud for complex videos or to save device resources.
  • Services like AWS Rekognition, Google Cloud Vision API, or custom TensorFlow models on a cloud server can handle this.

Workflow Integration

  1. Background Removal Workflow:

    • Add an option in the video editor to "Remove Background."
    • Process video frames for segmentation (real-time or batch).
    • Display the output with transparent or replaced background.

  2. Replacement Options:

    • Provide a gallery of replacement backgrounds (e.g., office, park, studio).
    • Allow users to upload custom images or videos as backgrounds.

  3. Preview and Post:

    • Show a real-time preview of the video with the replaced background.
    • Allow users to refine or accept before posting.

Technical Considerations

  1. Performance:
    • Optimize models for real-time use.
    • Provide a "lite" mode for lower-end devices.
  2. Video Quality:
    • Avoid artifacts around edges (hair, moving objects).
    • Allow manual adjustments (e.g., blur or soften edges).
  3. Storage & Processing:
    • Use device storage for drafts but offer cloud processing for longer videos.

Next Steps

  1. Choose a Background Removal Tool:
    • Decide between open-source, custom models, or a commercial SDK.
  2. Prototype the Feature:
    • Build a small prototype focusing on real-time segmentation and replacement.
  3. Test and Optimize:
    • Test on different devices for speed and accuracy.
  4. Integrate with the App:
    • Add this feature to the existing workflow, including save and post options.
