How to manually rebuild Media Cache Files in Premiere Pro

When you’ve been working with Premiere Pro for a while, importing large amounts of data and creating countless projects, there comes the time when you might want to clean up your Media Cache Database. It’s an exotic combination of various files that Premiere creates to make playback and scrolling during editing as fast as possible.

To access this option, head over to Preferences – Media and hit the big Clean button.

While this will clear out the number of entires in Premiere’s database, it may leave some generated files on the hard drive, or worse, it may lead to some of the temp files no longer accessible. As a result, your project appears to play back without audio or video in the timeline.

I had this recently on a larger (and important) project of mine, and I was wondering how to make Premiere rebuild those files from scratch, if they can’t be found anymore. Turns out the solution is relatively simple: with Premiere closed down, we delete ALL files in two (or three) folders, and when Premiere re-launches it will rebuild everything that’s needed for your current project.

Here’s how to do it:

  1. close Premiere
  2. head over to the Media Cache Folder (path seen in the screenshot above)
  3. delete the Media Cache folder
  4. delete the Media Cache Files folder
  5. delete the Peak Files folder (if you have one)
  6. relaunch Premiere and load your project

At this point you may have to wait a moment or two depending on the size of your project. Watch the progress bar at the bottom right as it goes through every file that needs to be regenerated (or conformed).

Thanks to Screenlight TV for explaining this in more detail.

Discovered in 2019

Where does the time go? It felt like only yesterday that I’ve started my “discoveries” category, and with it the idea that I’d like to paste useful links into a place that would make it easy for me to find them. Turns out I’ve been actioning such findings in different ways, and it also goes to show how little time I spend with important ventures like this.

So perhaps then, as another way of utilising this idea, I’ll have an annual post with important discoveries, or one whenever I feel like I’m running out of tabs in my various browsers. I might even add to this post once it’s published so I won’t clutter up my website with Discoveries alone.

How to delete multiple projects in iMovie

I edit most of my bike videos in iMovie on macOS. It’s quick and easy for what I need to do, and although it’s not a professional editing package, it’s very good for quick tasks. And it’s free if you own a Mac (or at least it once came free with it).

Over time I’ve amassed a huge library of videos that are still part of my library, and there comes a time at which even the biggest hard disk runs out of space. I already knew that I could delete a single project by selecting the project from the home page, then using the little disclosure menu on the bottom right and select Delete Project.

DAZ Studio 4.12 Beta – a Sneak Peek – 3D Shenanigans #25

On today’s stream I’ll take sneak-peek at the new features in the brand new beta version of DAZ Studio 4.12. It was released earlier this week, and it’s all about better animation tools: integrated features from GraphMate and KeyMate, and IK Chains inside a scene hierarchy.

The highlights in this version are:

  • overhaul of the regular timeline
  • integration of the KeyMate and GraphMate functionality
  • addition of IK Chain feature for regular scenes
  • Viewport Performance setting finally defaults to “best” rather than “none”

There’s a complete list of new features is here, and the full changelog can be found here.

You can download the beta from here (it installs in parallel to the release version and will not affect your current settings or library).

Patreon Supporters can get download the scene files from this stream here.

Many thanks to Mike Myers for suggesting this topic for today’s stream ☝️

Trying out Chocofur Asset Management for Blender 2.8 – 3D Shenanigans #24

In this episode I’ll try to install the Chocofur Asset Management add-on for Blender. It’s recently been updated to Blender 2.8, but right now not so easy to find on their website. Chocofur have lots of free assets to try out, perhaps we can work out how this works together.

I was unable to get this thing going during the live stream, so I’ve made another video the next day to explain how to make it work.

The podcast episode is only the second part, which contains the solution to this mind bending puzzle.

DAZ Studio 115: Parametric Light Objects in Iray

In this episode I’ll give you an introduction to the various parametric light objects we can create from the menu, how to use them and how to tweak their respective parameters as they apply to the Iray render engine.

Here’s the link about Colour Temperature I’ve mentioned: https://en.wikipedia.org/wiki/Color_temperature

Using Blender on a Laptop with a Trackpad

After futzing CentOS 7 on my old Samsung Q330 laptop, I thought it would be fun to see if the old hardware from 2010 would be capable of running Blender. After all, the team have recently added CentOS as a new pre-built package to the list of downloadable options, and for me that was the perfect opportunity to try it out.

Turns out my Q330 only runs OpenGL Version 2.1, which means it can’t run Blender 2.8+. However it’s still capable of running 2.79, and it made me smile to see it full screen.

Of course trying to move anything on the screen proved to be difficult, because I had never done that before with a standard trackpad. My Mac has one, and it behaves beautifully with gestures out of the box, but I guess Windows and Linux users don’t have that luxury, even if a trackpad is present.

How do we navigate 3D space in Blender then, if there’s no mouse nearby? Well I’ve just found out, and I’d love to share it with you. I’ve only been able to test this in Blender 2.79, but I’m assuming

Duplicating an object along a path in Blender 2.8

The other day I tried to create a simple necklace in Blender 2.8, only to find out that the way I’ve once learnt from Blender 2.79 and below using DupliFaces no longer works. This feature has been removed from Blender 2.8. Thankfully there’s an easier way to do this, using the Array and Curve Modifiers.

For this example I’ll create a circle for our path, and an object I want to duplicate on it. Perhaps a UV Sphere. Make sure to apply all transformations after any scaling operations with CTRL + A.

Editing DAZ clothing using a reference figure in ZBrush

Even though I own it, I know very little about ZBrush. It may forever remain a mystery for me – like driving a car or getting excited about Team Sports. It’s just… not for me. Be that as it may, I’ve often wondered how clothing manufacturers use a character as a reference to make or update clothing geometry in ZBrush. Perhaps a jacket that doesn’t quite fit, or some boots that need a quick adjustment.

The challenge here is that both the character and the clothing need to be imported into ZBrush, and we need to be able to adjust the clothing only, while seeing the character in the background as a reference so we can work around it.

While the art of sculpting in ZBrush entirely eludes me, I believe I have finally understood the overall workflow. Before I forget it again, I thought I’d share it with you and my future self. Let’s see how we can transfer a clothed Genesis 3 figure from DAZ Studio 4.11 into ZBrush 2019.1, make adjustments on an item, and then bring it all back with a few clicks.

Building a scene with dForce Magnets – 3D Shenanigans #23

In this live even I’ll show you how to use the dForce Magnets by Esha and Riversoft. I’ve had this question many times, perhaps my approach to using them helps to inspire you.

I’ll start with a demo of how to add magnets to an plane object and explain how this product differs from a regular rigid follow node. Then I’ll move on to building a bed scene in which I’ll drape a duvet/sheet over a sleeping character.

Enjoy!
