User: how many water should a man drink of 80kgs
Assistant: The amount of water a person should drink can vary based on several factors, including activity level, climate, and overall health. However, a common guideline is to drink about 30 to 35 milliliters of water per kilogram of body weight.

For a man weighing 80 kg, this would be:

- **30 mL/kg**: 80 kg × 30 mL = 2400 mL (or 2.4 liters)
- **35 mL/kg**: 80 kg × 35 mL = 2800 mL (or 2.8 liters)

So, a general recommendation would be to drink between 2.4 to 2.8 liters of water per day. It's also important to listen to your body and adjust your intake based on thirst, activity level, and environmental conditions.

User: how is it called the view where is only one video on the screen on davinci resolve, so that i can set a keyboard shortcut to it? 
Assistant: In DaVinci Resolve, the view where only one video is displayed on the screen is typically referred to as the **"Single Viewer"** mode. This mode allows you to focus on one clip at a time, which can be particularly useful for detailed editing or color grading.

To set a keyboard shortcut for toggling the Single Viewer mode, you can follow these steps:

1. **Open DaVinci Resolve**.
2. **Go to the "Keyboard Customization"**:
   - Click on "DaVinci Resolve" in the top menu.
   - Select "Keyboard Customization" from the dropdown menu.

3. **Search for "Single Viewer"**:
   - In the Keyboard Customization window, use the search bar to look for "Single Viewer."
   - You should find an option related to toggling the Single Viewer mode.

4. **Assign a Shortcut**:
   - Click on the action for Single Viewer.
   - Press the keys you want to assign as a shortcut.
   - Make sure the keys you choose are not already in use for another function (if they are, you may need to reassign or remove the existing shortcut).

5. **Save Your Changes**: Once you've set your desired shortcut, make sure to save your changes before closing the Keyboard Customization window.

Now you should be able to toggle the Single Viewer mode using your new keyboard shortcut!
User: how to do object removal davinci resolve
Assistant: Object removal in DaVinci Resolve can be accomplished using the **Fusion** page or the **Color** page, depending on the complexity of the object you want to remove. Here’s a basic guide on how to perform object removal using both methods:

### Method 1: Using the Color Page (for simple removals)

1. **Import Your Clip**: Open DaVinci Resolve and import the clip from which you want to remove an object.

2. **Go to the Color Page**: Click on the "Color" tab at the bottom of the interface.

3. **Add a Node**: Right-click in the node area and select "Add Node" > "Add Serial" to create a new node.

4. **Use the Window Tool**:
   - Select the new node.
   - Click on the "Window" tool (the icon that looks like a circle or square).
   - Choose a shape (like a circle or polygon) to create a mask around the object you want to remove.

5. **Track the Object**:
   - With the mask selected, click on the "Tracker" panel (the icon that looks like a crosshair).
   - Track the object throughout the clip to ensure the mask follows it.

6. **Use the Clone Tool**:
   - In the same node, select the "Clone" tool (the icon that looks like a stamp).
   - Use the clone brush to paint over the object you want to remove. You can adjust the source point to clone from a nearby area.

7. **Refine the Edges**: Adjust the mask and feathering to blend the cloned area with the surrounding footage.

8. **Render Your Clip**: Once you’re satisfied with the removal, go to the "Deliver" page to render your edited clip.

### Method 2: Using the Fusion Page (for more complex removals)

1. **Import Your Clip**: Open DaVinci Resolve and import the clip.

2. **Go to the Fusion Page**: Select the clip in the timeline, then click on the "Fusion" tab at the bottom.

3. **Add a Background Node**: In the Fusion workspace, you will see a MediaIn node. You can add a Background node if needed.

4. **Use the Paint Tool**:
   - Add a "Paint" node by right-clicking in the node area and selecting "Add Tool" > "Paint."
   - Connect the Paint node to the MediaOut node.

5. **Select the Clone Tool**: In the Paint node, select the "Clone" tool from the toolbar.

6. **Clone Over the Object**:
   - Set a source point by holding down the `Option` key (Mac) or `Alt` key (Windows) and clicking on the area you want to clone from.
   - Paint over the object you want to remove.

7. **Animate the Clone (if necessary)**: If the object moves, you may need to animate the clone source point or use keyframes to adjust the cloning as the object moves.

8. **Render Your Clip**: Once you’re satisfied with the removal, go to the "Deliver" page to render your edited clip.

### Tips:
- **Use High-Quality Footage**: The better the quality of your footage, the easier it will be to remove objects seamlessly.
- **Practice**: Object removal can be tricky, especially with moving objects. It may take some practice to get it right.
- **Use Reference Frames**: If the background is complex, consider using reference frames to help with cloning.

By following these methods, you should be able to effectively remove unwanted objects from your footage in DaVinci Resolve.
User: how to add levels effect davinci resolve
Assistant: In DaVinci Resolve, the **Levels** effect is typically used to adjust the brightness and contrast of your footage. You can achieve this using the **Color** page or by applying the **Levels** effect in the **Effects Library**. Here’s how to do it using both methods:

6. **Render Your Clip**: Once you’re satisfied with the adjustments, go to the "Deliver" page to render your edited clip.

### Method 2: Using the Effects Library

2. **Go to the Edit Page**: Click on the "Edit" tab at the bottom of the interface.

3. **Open the Effects Library**: If the Effects Library is not visible, click on "Effects Library" in the upper left corner.

By following these methods, you should be able to effectively add and adjust the Levels effect in DaVinci Resolve.
