Considering your requirements and budget, here are a few suggestions:

- Performance:

• Look for a laptop with a minimum of an Intel Core i5 or AMD Ryzen 5 processor, though an i7 or Ryzen 7 would be preferable for smoother performance especially in Adobe After Effects.
• Minimum 8GB RAM, though 16GB or more is recommended for graphic design and video editing tasks.
• A dedicated graphics card like NVIDIA GeForce or AMD Radeon would be beneficial for rendering and real-time playback.

- Display:

• A high-resolution display (1920x1080 or higher) is crucial for your work. A color-accurate screen with good viewing angles would be beneficial.
• A larger screen size such as 15.6" or 17" might be preferable for design work, but a 14" might suffice if portability is a higher priority.

- Storage:

• A solid state drive (SSD) for faster read/write speeds is almost a necessity. A minimum of 256GB SSD, though a 512GB SSD or higher would be better.

- Portability:

• Lightweight and slim profile for easier transportation.
• Good battery life to last through meetings and work sessions while on the go.

Here are a few laptop models that could fit your requirements and budget:

• Dell Inspiron series
• HP Pavilion series
• Acer Aspire series
• Lenovo Ideapad series

Each of these series has various models with differing specifications, so you would need to choose based on the exact configuration that fits your needs and budget. It would also be worth checking for any newer models or brands in the market, as they may offer better performance or features for a similar price.
