How do you save computation cycles by NOT… - Apple Community
I think the effect will be negligible whilst he thinks it is large.
I could be wrong . . . what do you think?
It's certainly worrying him.

I exported a Project that was 13 minutes, 30 seconds long, as H264.
With sound the file is 1.59 GB.
Without sound the file is 1.57 GB.
Thus the audio is eating up only .02 GB, or 20.48 MB of drive space.
I remember at one time this would have been a HUGE file, 20.5 MB. The external hard drive on my Mac Plus was 20MB and considered fantastically massive. But by today's norms, it's negligible.
It stands to reason that:
a) Audio takes a minute amount of space compared to video
b) Processing video and audio takes a little more than processing just the video
In the grand scheme of things, this is really irrelevant.
Wear and tear... really?!
Without even looking at the video, a single word comes to mind.
It starts with "p" and ends with "noia".
But I will look at it, and if I find something worthy of mention, I will report back.
Luv the full stop analogy Ian. 🤣
The only time I’ve ever been concerned about audio in video is when an email MUST be used and you are looking to save every byte of info to get the email under the provider limits.

Thanks for the confirmation Luis. I was beginning to wonder whether I had missed something because when I am writing a letter I tend to omit punctuation in order to save ink. 🤭
Now thats a really good idea You should do it too when youre typing a letter on the computer Think how many function cycles you will save the system
Does exporting with Audio (when you don't need it) impact negatively on file size, export times and wear and tear on computer?
