Encoding presets in HandBrake

Posted on by

Back in the early days of online video, it was (for me) a three-step process. Shoot the video; edit the video; encode the video for uploading to (eventually) YouTube, Vimeo, Facebook, etc. And for a long time, encoding was a Dark Art. Lots and lots of hidden settings that — if properly optimized — resulted in a file that didn’t take 8 hours to upload and still look pretty good when streamed. I think most of that voodoo now happens behind the scenes and we mortals don’t have to think about it.

My net connection is via DSL and while it’s okay (8mbs) coming down, it’s damned slow going up, so even a short video can take a while to upload. To address the problem, I run my videos through a program called HandBrake. HandBrake is a tool for converting video from nearly any format to a selection of modern, widely supported codecs. It converts videos from nearly any format; it’s free and Open Source; and it’s Multi-Platform (Windows, Mac and Linux). And it’s free.

The program has been around for 13 years and I first used it to rip songs from CDs. Don’t have much call for that anymore but along the way I discovered it was really good at encoding video for streaming online. I won’t get into features here except to say the latest version has a bunch of handy presets. Experts can tweak and optimize to their heart’s desire.

I know, I know… this is getting long. I’ll hurry.

Yesterday I recorded a bit of a song I’m trying to learn and wanted to see what kind of video I could get recording directly to my iPhone using the built-in mic. Not all that great. And it was too big to email to my buddy Professor Peter, so I started playing with some of the new encoding presets in HandBrake. They had a few that appeared to be optimized for Gmail.

The original .mov file was about 224MB. The HB preset I usually use took that down to 69MB (1080p30). And the Gmail preset down to 15MB (720p30). I’m thinking, “That’s gonna look and sound like shit.” But when I compared the three, not to bad. Try to ignore the ‘vintage’ filter I mistakenly used (iMovie on my phone). Each of the samples is only 30 seconds.

Google PhotoScan

When Peter Smith suggested this app I said “thanks” but was thinking, ‘Not gonna come close to the image I get with my flatbed scanner.’ But I gave it a try and… pretty damned close. Rather amazing. I’ll probably keep using my scanner for some of the really old stuff because I can control the resolution and use Pixelmator to ‘repair’ the image as needed. But most folks won’t fuck with all of that. With this app you could breeze through a shoebox full of old photos in no time. One final thought: this video is very well done.

Timeline 3D

“Make timeline charts of world history, family trees, fictional stories or business deadlines.” I’m a sucker for timelines and I purchased this Mac app a few years ago to create a timeline for the company I worked for. Don’t think I ever got around to that but started playing with it recently. 5 minutes.

Deepgram finds speech with A.I.

“Searching through recordings is really difficult. In terms of workflow, usually the raw audio is transcribed into text, which is then fed into a search tool. If you transcribe using human transcription, it’s too time consuming and expensive. If you try to do it with automatic speech-to-text then search accuracy is the problem. […] Deepgram is an artificial intelligence tool that makes searching for keywords in speeches, private conversations and phone calls faster, cheaper and easier than the old way of doing things. Deepgram indexes audio files in more than half the time of a human transcriber, and costs only 75¢ per hour of audio.”

Amazing. Try it for yourself and see if it doesn’t blow your panties off.

AirPods

I spent some money on headphones back in the 70s. When I started at KBOA in ’72 all they had were these WWII-era Bakelite hockey pucks with a piece of vibrating tin inside.

When I saw my first pair of Sennheiser open-air headphones (in a magazine) I ordered a pair and paid for them myself. And, yes, I took them into the studio for my shift and took them with me when done. They were pretty expensive (for the time) and a bit fragile. But I sounded soooo good in those headphones. More accurately, I could hear what I really sounded like and that was important.

Fast forward several light years to the first iPods and the famous white earbuds that all serious music buffs hated. I loved them. They sounded fine to me and they fit my ears just fine. I’ve been using them ever since, pretty much every day.

In a few weeks Apple will start selling AirPods ($150) and I’ll buy a pair on Day One. And I might not be the only one. From Business Insider:

12% of U.S. consumers surveyed by Bank of America Merrill Lynch say they intend to purchase AirPods, apparently on the strength of Apple’s marketing, given that few people have actually seen and tried them out. This is a very bullish sign for Apple, says BAML. “12% of the US installed base could lead to up to an incremental $3bn in revenue,” writes the analysts.

“Apple’s marketing” is one explanation. Another might be that people like me have been using Apple earbuds for fifteen years and like them.

You are where your attention is

Excerpts from an article in New York Magazine by Andrew Sullivan:

“Then the apps descended, like the rain, to inundate what was left of our free time. It was ubiquitous now, this virtual living, this never-stopping, this always-updating. […] The engagement never ends. Not long ago, surfing the web, however addictive, was a stationary activity. At your desk at work, or at home on your laptop, you disappeared down a rabbit hole of links and resurfaced minutes (or hours) later to reencounter the world. But the smartphone then went and made the rabbit hole portable, inviting us to get lost in it anywhere, at any time, whatever else we might be doing. Information soon penetrated every waking moment of our lives.”

“A small but detailed 2015 study of young adults found that participants were using their phones five hours a day, at 85 separate times.”

“You are where your attention is. If you’re watching a football game with your son while also texting a friend, you’re not fully with your child — and he knows it. Truly being with another person means being experientially with them, picking up countless tiny signals from the eyes and voice and body language and context, and reacting, often unconsciously, to every nuance. These are our deepest social skills, which have been honed through the aeons. They are what make us distinctively human.”

Nest Cam Outdoor

My first impressions of this camera are very positive. Very easy to install and set up. Plug it in, connect to your wifi network and you’re done. The camera mount is magnetic so you can swivel the cylindrical camera to change the viewing angle. Good image, day and night and camera has a mic and speaker so we can communicate with any visitors.

There’s a Nest Aware option ($10/mo) that captures and stores video but that’s not something we need. But nice to have if we lived in a neighborhood with high crime or nosy neighbors. The camera is motion sensitive and can alert you when you have a visitor. I’m still getting familiar with the software but can monitor with iPhone app or from a browser on my laptop.

For you glass-half-empty types: Yes, a bad guy could rip this off the wall or cut the power cord or spray-paint the lens or just go in the back door. But for $200, this is a simple, effective security camera.
