fixed : compress video for WhatsApp (or eMail)

Question :

I would like to send a small piece of a video I just shot at a birthday party to a group of friends on WhatsApp, but it’s too big to upload.

How can I compress it for easy viewing on Whatsapp ?

 

Answer :

If you have shot the video on your iPhone you can send it right away, and iOS will do the compression for you.

However, if you already have the video on your Mac and you want to compress it before you send it using WhatsApp Desktop (for macOS), do this :

  • make sure you trim down the length of the video to a clip that only includes the most relevant part of the video
    • you can do this in QuickTime Player (included in macOS for FREE)
  • use Smart Converter (FREE from Mac AppStore) and choose ‘for iPhone or iPod’, then click ‘Convert’ to convert
    • this will convert to an .mp4 video with 1280×720 resolution at 30 frames per second and AAC sound (file size ca. 10MB per 10 seconds)
  • use Handbrake (FREE from handbrake.fr) and choose ‘Presets’ > ‘Gmail Large 3 minutes 720p30’, then click ‘Start’ to convert
    • 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) 

That’s it !

enjoy 😉

tip : quickly cut-out part of a picture in OSX

Question :

I have a nice picture I want to use in a presentation, but I don’t want the entire picture, just part of it.

Is there an easy way to cut the desired piece out ?

…even if I don’t have Photoshop ?

Answer :

Even if you don’t have Photoshop, cutting out part of a picture for (re)use in PowerPoint, Keynote, Word, Pages, your website, LinkedIn, FaceBook, etc. is very easy on your Mac :

1- open the picture in Preview app (usually that would only require you to double-click on the picture’s icon)

2- click on the Image-button (Edit button)

3- in the Editing-toolbar that appears, click on the Image-button (Selection button)

4- now the + (Plus sign) appears, so : click on one corner of the part of the picture you want to select and drag to the opposite corner [ you can do this rather ‘roughly’ ]

5- then the selection area appears [ normally a rectangle with dots in the corners and on the middle of the side ] ; drag the dots so, that the selection area exactly fits the part of the picture that you want to take out

6- then press the ‘Copy key-combo’ (CMD + C)

7- now choose “New From Clipboard” from the “File”-menu, or press the ‘New key-combo’ (CMD + N), and you will get a new window with only your ‘cut-out part’ in it

8- if that looks as you envisioned it, choose “Save” from the “File”-menu, or press the ‘Save key-combo’ (CMD + S), and save the cut-out picture as a JPEG or PNG (or TIFF)
