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.

Repair Macbook Audio Hardware Issue (Solved!)

Recently, I experienced a rather strange problem with my 5 year old Macbook Air: The audio stopped working completely. Even plugging a headphone into the earphone jack produced no sound. Going to the Sound Preferences produced the classic error of: No output devices found.

Upon googling online, I tried most, if not all, of the recommended fixes:

  • Reset NVRAM
  • Reset SMC
  • Update to latest iOS
  • Create a testing account on safe mode
  • Restarting the computer
  • Apple Hardware Test (Produced an error code of VFF001: There may be an issue with the audio hardware)
  • Plugging in and out of the earphone jack multiple times
  • Cleaning the earphone jack by blowing air/ vacuuming dirt
  • Calling the Apple Support hotline

None of the above helped, unfortunately. Hence, my situation was in the most serious category of Audio problems for MacBook. Online sources highly suspected that it was a hardware issue (and hence required a expensive repair).

First, I stumbled upon Solution 1:

Solution 1 to Macbook “No Output Device Found” Audio Problem

The first solution is to use a USB to Audio adapter such that you can direct the audio through your USB port to your earphones. It worked very well in my case. There should be many brands such as Sabrent (listed below), or Flujo, etc.

For speakers, a similar solution is USB speakers, such as the one below.

Solution 2 to Macbook “No Sound” Problem

Afterwards, I encountered a miraculous Solution 2 to my Macbook Air audio problem. I booked a “Genius Bar” appointment at the official Apple Store. The support staff entered a mode called “Triage Mode” — which apparently only Apple staff can enter. She performed a diagnostic test that indicated that everything was working correctly. Upon shutting down and restarting, I heard the characteristic chime of Apple start up sound, something which I have not heard in weeks.

Thereafter, the audio problem miraculously solved itself, the “Internal Speakers” showed up once again as one of the output devices! The staff herself was surprised. This is quite miraculous as every source I read indicated that it was a hardware problem that could only be resolved by replacing the “logic board” or some other hardware component of the MacBook.

MacBook Air for Math Students

Tired of “blue screens of death” that are so common in Windows? Don’t want to wait 10 minutes for Windows to “start up”? Switch to Mac OS!

My old computer (ASUS) has lasted me 5 years, but has recently gotten to the point that it slows down to a crawl. Booting up Windows takes up to 15 minutes, and “blue screens of death” occurs extremely frequently. It hasn’t spoiled completely yet, I still use it for printing documents.

I have since switched to MacBook Air, and so far it has been a great experience.

Tips for Math Students using MacBook Air / Pro

For Math students, some apps that you may want to install are MacTeX. It is the LaTeX Mac version. The initial download is over 2 GB, so it might take a while. I downloaded the installer from the main website, it took around one hour.

Another app is Google Chrome, which works very well on Mac. WordPress.com runs better on Chrome, for instance the LaTeX expressions are rendered better on the Chrome browser versus the Safari browser.

MacBook Air is one of the lightest notebooks around. The downside is that it does not have a few features, for example Ethernet Adapter and Optical Drive. Not to worry, one can purchase add-ons to remedy the problem. (Listed below)

MacBook takes some time to get used to, hence it is good to play around with it to discover the hidden shortcuts. For instance, Copy on Mac is command-C instead of control-C.
