fixed : convert video for WhatsApp

Question :

I have a short video file (a movie clip) that I want to share with my friends on WhatsApp. When I drag&drop it into the WhatsApp.app in macOS, the file appears to start uploading… but when done, there is no preview shown and no Play-button, just a file icon… as if it were an unknown or incompatible type of file…

What can I do to fix this ?

Answer :

Before uploading your video file to WhatsApp, you must make sure your video file meets WhatsApp’s file requirements :

  • video format preferably MP4 in H.264 or MPEG-4 codec ( MKV, AVI or 3GP will also do )
  • audio format preferably AAC ( or AC3 codec )
  • file size smaller than about 16MB ( in reality even 18MB might be okay )
    • usually, this means your movie clip will be about 90 seconds, but by tweaking the display size and the frame rate ( fps ) you can even squeeze 3 minutes or more into about 16MB

Do this to check your video’s specifications :

  • right-click ( CTRL-click ) on the movie clip’s icon
  • select “Get Info” from the popup-menu
  • in the window that opens, check these :
    • the file name either has the “.mov” or “.mp4” file extension
    • at “Size:” less that 18MB should be listed
    • at “Codecs:” either “H.264” or “H.264, AAC” is listed

If these are all okay, you should be able to just drag&drop the movie clip into the macOS WhatsApp.app.

If not, you will have to convert the movie clip. To do this conversion, do this :

  • first, download the FREE OmniConverter.app ( by 7littlemen ) from the Mac AppStore :
  • then, open the OmniConverter.app and click on “Convert Video” from the list on the left
  • then, drag&drop your movie clip file onto the OmniConverter window
  • now, at the right of the arrow (in the middle), check if “MP4” is listed and the file size is less than 18MB
    • if you do not see “MP4” listed at the right of the middle arrow, click the Format-button
      • in the window that opens, select the “Device”-tab
      • then, select “iPhone” from the list on the left
      • then, select the “iPhone HD” option
      • now, click the Confirm-button
    • if you see a file size larger than 18MB listed at the right of the middle arrow, click the Edit-button
      • in the window that opens, at “Video”>”Encoder:” select “H.264”
      • and at “Audio”>”Encoder:” select “AAC”
      • leave the rest as is and click the Confirm-button
  • back in the Convert Video window, click on the Start-button ( circled arrow icon, at the right )
  • now, wait for the conversion to complete
    • if the file size already was less than 18MB, you’re usually okay and you will not need to do extra compression
    • if the file size was over 18MB, do this :
      • open the OmniConverter.app and click on “Compress Video” from the list on the left
      • drag&drop the .mp4-video you’ve just converted onto the OmniConverter window
      • check if the file size listed at the right of the arrow (in the middle) is less than 16MB
        • if so, click the Start-button on the right
        • if not, click the Edit-button (below the arrow)
        • in the window that opens, set the “Quality:”-slider in-between “Mid” and “High”, set “Resolution:” to “720P” and set “Frame Rate:” to “24 FPS”
        • if at “Size:” it now says anything less than 16MB, click the Confirm-button
        • if at “Size:” it says anything over 30MB, set “Resolution:” to “480P”
        • if at “Size:” it says anything between 20MB and 30MB, set the “Quality:”-slider to “Mid”
        • now, if at “Size:” it still says anything over 18MB, start tweaking the available settings until at “Size:” it says about 15MB ( see how much the file size decreases when you tweak each setting to find the optimal combination of settings )
        • when done, click the Confirm-button
      • now, in the “Compress Video” window, click the Start-button
      • …and wait for the compression to finish

After the file conversion, drag&drop the converted movie clip into the WhatsApp.app to share it with your friends…

That’s it !

fixed : convert old .flv movie files to .mp4 for free

Question :

I’ve found this old Flash videos (in .flv format) on an old hard disk and I want to play them on my Mac / iPhone, but QuickTime gives a “The document could not be opened”-error, stating “The file isn’t compatible with QuickTime Player.”

Is there a simple way to convert them to a video file format that QuickTime can handle (preferably .mp4) ?

Answer :

Yes, there is : the FREE Smart Converter app can do this for you very easily. Just do this :

  • open the SmartConverter.app
  • when the Smart Converter window opens, drag&drop the .flv-video file that you want to convert onto it
  • then, click the Mac-button (in-between the QuickTime and iPad buttons)
  • then, click the blue Convert-button (bottom right) and wait for the conversion to finish
  • then, after noticing that the blue Convert-button has changed into a blue ShowFile-button, click on it
  • in the Finder-window that opens, click on the converted video file (that now has an .mp4 file extension) and it will open in the QuickTime Player app

That’s it !

fixed : quickly rotate a movie file in macOS 10.15 Catalina

Question :

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 ?

 

Answer :

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)
  • then wait for the processing to end…

…and you’re done 😉

That’s it – enjoy !
