Five DaVinci Resolve Tips to Boost Your Productivity

  1. Drag and drop folders of footage into Resolve with their folder structures intact. No more creating bins in Resolve for your various footage items. The solution is to drag and drop the folder from your operating system on the area which says “Master” which is typically on the left side of the Media pool. This will automatically preserve all your folder structures.
  2. Auto sync audio and video files. Many professional video productions will involve separate audio files from the video. Typically you have a low quality audio track embedded to the video coming from the video camera’s microphone and then you have a high quality set of audio files recorded with a boom or lavalier. When you start to edit such a setup in Resolve, one of the first steps is to sync the high quality audio with the video. To do that, simply select both the audio and the video clips (or even just the bins containing the audio and the bins containing the video) in the media pool and right click and choose “Auto Sync Audio”. From there I prefer the “Based on waveform and append tracks” because it will keep also the original audio in place for some sanity checks. It might take a while to complete and then it will give you a summary of the results. If you closed the summary, don’t worry, you can easily see which clips were synced with the audio by looking at them on the timeline. The ones that were successfully synced, will contain two audio tracks instead of just one.
  3. Use the 3D qualifier for great results when doing secondary color grading. You can find it in the qualifier tab. Then just draw a stroke over the colors you want to isolate for grading. View the matte from the magic wand looking symbol above the video monitor.

4. Temporarily disable/enable snapping mid-operation with the N-key. When you are dragging a clip on the timeline and realize that the snapping preference is not working for you, you can press N to temporarily diasable or enable snapping.

5. Automatically name your exported video using the project name. If you typically export your video files from the render queue using the name of the actual project, it may be a bit annoying to type in the File Name field, since you have already typed it once when naming the project. It would be nice if Resolve could automatically suggest the project name as the export name, but in the meanwhile you can type %Project Name in the field and then hit “Add to Render Queue” to get the same result. There are other variables you can access as well like %Timeline Name and %Render Resolution. The easiest way to access the variables in to just type a % in the field and Resolve will suggest all kinds of possible variables to you. It’s enough to just type %Proj and then hit enter in order to get the Project Name variable.

Blender keyboard shortcuts for working with nodes

Being able to work efficiently with different kinds of nodes in Blender is becoming increasingly important. These basic node related keyboard shortcuts should work in all of the Node editors in Blender including material nodes, the compositor and geometry nodes.

Add new node: shift+A

Just like you can add new objects with shift+a, the same shortcut also works for adding new nodes. If you want to immediately enter the search mode, read about the next shortcut below.

Add new node and search immediately: shift+A, then S

If you want to search for the name of the node instead of browsing through the categories, hit s immediately after hitting shift+a and it will take you to the search bar.

Disable a node: M

Sometimes you just want to see the results of a node tree without a certain node. In that case you can easily mute a node by selecting it and hitting M on your keyboard.

Delete a node: X

Just like you would expect, hitting X on the keyboard will delete the selected node(s).

Delete with reconnect: ctrl+X

If you want to delete a node in the middle of a node tree and automatically connect the node that came before the deleted node to the node where the deleted node was connected to, simply hit ctrl+X to delete the node from between.

Backdrop Zoom: V and alt+V

If you need to zoom out of the backdrop image to see it completely, just hit V on the keyboard. Zoom in by pressing alt+V.

Duplicate a node: shift+D

To make a duplicate of the selected node(s), just hit shift+D on the keyboard.

Connect a node to the viewer: ctrl+shift+leftclick

If you want to quickly connect a node’s output to the viewer node to see the result of the node, just hold down shift and control and left-click on the node you want to connect.

Cut a node connection: ctrl+rightclick-drag

If you want to cut a node connection, hold down control and the right mouse button and drag over the connection line.

Collapse node: H

Sometimes you want to collapse a node so that it takes less space. To do that, simply select the node and hit H on your keyboard and the node inputs will no longer be visible. If you want to reopen a collapsed node, simply hit H again.

Create node group: ctrl+G

Grouping nodes together allows you to simplify your node trees. By grouping several nodes together it is like combining them so that they appear to be just a single node. Simply select the nodes that you want to group together and hit ctrl+G. Note that all node types cannot be grouped together. For example you can’t put the “render layers” node in a node group.

Enter or exit node group: tab

After grouping nodes, Blender will automatically take you inside the group. To exit the node group, press tab on the keyboard. Similarly, to enter a node group, select the group and press tab.

Increment integer value in a database field using WPDB

Sometimes you need to update values incrementally in your WordPress database. You might for example have an upvote feature to which you automatically add points in an incremental fashion.

It was surprisingly hard to find examples of how to do this using Wpdb. But here’s an example of doing just that:

/* Have to use wpdb->query instead of wpdb->update because the latter assumes strings  */
  $results = $wpdb->query($wpdb->prepare("UPDATE foodsenglish SET popularity = popularity + 1 WHERE dbID = %d", $foodIdToSendThePointFor), ARRAY_A);

Blender Video Editor Tips

Blender, being the Swiss-army-knife -tool that it is, can also do video editing. Setting up a video editing layout is easier than ever with the new “Workspace” -system of Blender. Simply click on the + button at the end of the workspace tabs and choose Video Editing –> Video Editing. Here’s a picture:

When using Blender as a video editor, a couple of questions immediately come to mind:

  1. How do I perform a cut? Answer: Simply press K.
  2. How do I perform a ripple delete (an edit in which the gap of the deleted content is automatically closed)? Answer: There is no ripple edit feature at the moment, but it can still be done very quickly by hitting “Del” to delete, then “Page up” to jump the playhead to the previous cut and finally “Backspace” to “Close gap”.
  3. How can I “render the timeline” for better playback performance? Answer: The best way might be to create Proxies. In the Proxy workflow, Blender will create new, better performing versions of your video files and use them for better work speed. These are the steps you need to take to enable Proxies in Blender Video Editor:

First find the Proxy Panel. It lives usually on the right side of the Sequencer (timeline looking panel). Select the clips you want to create a proxy for in the sequence. Click on “Set selected strip proxies” to set these clips up for proxy creation. It will ask for a desired proxy resolution. Then click “Rebuild Proxy and Timecode Indices”. Blender should now start creating the proxy files, next to your original files (although this location can be changed in the settings). It might take a while, but after it’s done, your playback should be much better.
