this will convert to an .mp4 video with 1280×720 resolution at 30 frames per second and AAC sound (file size ca. 2MB per 10 seconds)
Note : even though the frame rate and screen size are the same, the ‘Gmail’-ready file will be much smaller than the ‘iPhone’-ready file, even though (or rather ‘because’) this comes with the downside that quick-moving objects will blur in the ‘Gmail’-ready video (compared to the ‘iPhone’-ready video that hardly has any blur and is similar in size and quality to the ‘Fast 720p30’ preset in Handbrake)
I have been using Jacksta Media Recorder for a long time now, and it has always worked marvelously for me when I need to download a video. Jaksta can download nearly any online video that I can watch in Safari.
But recently, Jaksta does download the exact videos I want, but the downloads turn out to be .mp4 files that QuickTime hangs on when trying to play them…
What can I do ?
The exact reason for this is unknown, but it might have something to do with the fact that not all browsers play HTML5-videos using the same technology.
It turns out that your solution is to use the Google Chrome (or Firefox) web browser – instead of Safari – with Jaksta running in the background. That way, when you play the online video in Chrome (or Firefox), the file that Jaksta downloads will be a .mp4 video that QuickTime can play without any problems.
I have a movie-file that was shot on an iPhone in portrait-mode, but I think it will look better when viewed in landscape-mode. It’s a video of you cat playing on the carpet, shot from above, so both portrait-mode and landscape-mode are okay for viewing, but as we prefer to view video’s on out TV it would make more sense to have it in landscape-mode.
How do I do that ?
In MacOSX and OSX rotating photos was easily done in iPhoto or Photos.app, but rotating video couldn’t be done in iPhoto or Photos.app – that had to be done in video editing software like iMovie, or a dedicated video-rotation-app.
In macOS 10.15 Catalina, rotating video 90 degrees can be done extremely simple in the Finder :
open the Finder (click out of all apps until you have only the Desktop to look at)
open a New Finder Window by typing CMD and N keys on your keyboard simultaneously (or goto Finder > File > New Finder Window)
locate the video-file (if you know it’s name, typ it in the Search-bar, else browse to the file if you know where it’s located)
then click on the file name to select it
the video preview will now come up on the right side, with various info and some buttons below it
to rotate your video 90 degrees counter-clockwise, click on Rotate Left
to rotate your video 90 degrees clockwise, press the ALT key on your keybord and click on Rotate Right (in the same spot where the Rotate Left button used to be)
