iMovie Transition Glitch

iMovie “Corrupted” Frames between two video clips

iMovie is a great free movie editor for Mac. However, an annoying bug is that when two video clips are put together, there can often be “corrupted” frames, glitch, or even choppy video between the two clips.

Simple solution to iMovie Transition Glitch

There are some complicated solutions online, such as re-importing the video clips in certain formats.

However, a simple solution that I tried and tested to work in most cases is to try trimming off a few seconds from the start of the affected video clip. Or even adding a transition effect where the problem arises may work.

To explain more precisely, suppose the problem arises in between A -> B, where A and B are video clips. Then, you can try trimming off a few seconds off the start of video clip B, or adding a transition effect between A and B. (If there is already a transition from A -> B, try removing it!)

Another solution to iMovie Transition Bug

Another solution that I tried and works in some cases, is to export the movie via File -> Share in Best (ProRes) Quality, with Better Quality Compress.

Best (ProRes) Quality and Better Quality Compression may solve your iMovie glitching bugs.

Install Windows on MacBook (Fast and Easy method)

Basically, you just need to follow the instructions in the YouTube video below. It is very easy and fast. The key software is VirtualBox.

You can download the official Windows 10 ISO disc image here: https://www.microsoft.com/en-gb/software-download/windows10ISO

Note that Windows 10 (Home) is free (you don’t have to activate it) and you can use it with only very minor restrictions.

Overall, the process to install Windows 10 on a Mac (using VirtualBox) is much easier than I expected.

Total time taken: Around 30-40 minutes (possibly faster if your download speed and RAM is fast)

Total cost: $0

Total space needed: Around 10-20 GB is needed initially. VirtualBox allows “dynamically allocated disks” which are faster to create and can grow to larger sizes. For example, if you set 50GB as your disk space (but only use 10 GB) then it will only occupy 10 GB on your Mac.

How to keep Python / R Running on Mac (without screen lock or sleep)

When the Mac (or MacBook) is running for a long time, it is very liable to do one of the following things:

  • sleep
  • screen saver
  • lock screen

The problem is that your Python program or R program running in the background will most likely stop completely. Sure, it can resume when you activate the Mac again, but that is not what most people want! For one, it may impact the accurate calculation of elapsed time of your Python code.

Changing settings via System Preferences -> Energy Saver is a possible solution, but it is troublesome and problematic:

  • Have to switch it on and off again when not in use (many steps).
  • Preventing sleep may still run into screen saver, screen lock, etc.
  • Vice versa, preventing screen lock may still run into Mac sleeping, etc.

The solution is to install this free App called Amphetamine. Despite its “drug” name, it is a totally legitimate program that has high reviews everywhere. What this app does is to prevent your Mac from stopping, locking or sleeping. Hence, whatever program you are running will not halt till the program is done (or when you switch off Amphetamine).

It is a great program that does its job well! Highly recommended for anyone doing programming, video editing or downloading large files on Mac.

Python (Anaconda) does not work with MacOS Catalina!

This is just to highlight that the Anaconda Python Distribution does not work with the latest MacOS Catalina. I only realized upon trying to open Anaconda Navigator, after installing Catalina.

The only (good) solution seems to be reinstalling Anaconda.

MacOS Catalina was released on October 7, 2019, and has been causing quite a stir for Anaconda users.  Apple has decided that Anaconda’s default install location in the root folder is not allowed. It moves that folder into a folder on your desktop called “Relocated Items,” in the Security folder. If you’ve used the .pkg installer for Anaconda, this probably broke your Anaconda installation.  Many users discuss the breakage at https://github.com/ContinuumIO/anaconda-issues/issues/10998.

Night Mode for Mac

Apple has released a mode called Night Shift for iPhones and iPads. What it does is it reduces blue light from your phone in the evening/night so that one can sleep better. Blue light is known to be unnatural since throughout human history (before Edison), humans have lived in darkness at night. Fire from candles/lantern is Red light, which is considered not as bad as Blue light.

For Mac, there is no such thing as Night Shift (yet), the best alternative is f.lux. I recommend the “classic f.lux” mode over the default, as the default is too extreme (overly red).

Other than improving sleep, another factor it can help with is eye strain.
