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 : quickly create GIF from QuickTime or MP4 video

Question :

For my social media I regularly want to create a .gif-animation from small clip out of an .mp4-video file that I have, but I don’t have a lot of video-editing skills or specialised software.

Is there a simple way to do this ?

 

Answer :

There are lots of ways to do this. And no video-editing skills are required to do the most basic, but with some editing you can quickly get better results.

I would recommend buying the $5 GIF Brewery 3 from the Mac AppStore and doing the editing in QuickTime (or iMovie).

The recommendations for a good GIF-animation for most social media are (suggested by .gif-database GIPHY) :

  • duration of about 6 seconds (shorter is better)
  • file size close to 8MB (smaller is better)
  • video resolution of 480 pixels (or 720 pixels maximum) on the shortest side (depending on either landscape or portrait view, or square, or any custom size)
  • total number of frames of 100 maximum (less is better)

If you just want to turn part of an existing video into a GIF, do this :

  • get GIF Brewery 3 from the Mac AppStore ( the $5 price tag is worth it if you plan on doing this more frequently )
  • first, open the video source in QuickTime.app
  • then, in the top menu bar, click on “Window”
  • then, in the pulldown menu, click on “Movie Inspector”
  • then, check out the number that is at “Encoded FPS” and remember it (you need this later)
  • then close QuickTime.app
  • now, open your source video in GIF Brewery 3
  • then, in the video slider below your video, slide the green slider to match the first frame of your desired GIF
  • and slide the red slider to where you want your GIF to end
    • click on the PLAY-button (black triangle left of the video slider) to preview your GIF
    • if the preview-length is not okay, readjust the green and/or red slider to improve your clip
  • now, in the editing window, click on the Resize-button top left
  • then, in the popup window, make sure “Maintain aspect ratio” is checked
  • then, move the Scale-slider until either Width or Height is 480px (if the clip size is less than 5 seconds, you could also stop the Scale-slider at 720px)
  • now, in the editing window, click the Settings-button top right
  • then, at “Frames Per Second” set the fps to match the “Encoded FPS” of the original video
    • again, click on the PLAY-button (black triangle left of the video slider) to preview your GIF
    • if the preview-speed is too slow, adjust the Speed-slider to a higher value (anything less than 110%, even 103%, will usually do)
    • if the preview-speed is too fast, adjust the Speed-slider to a lower value (anything over 95% will usually do)
  • then, make sure there’s a checkmark at “Optimize GIF colors”
  • then, adjust the ColorCount-slider to 48
    • again, click on the PLAY-button (black triangle left of the video slider) to preview your GIF
    • if the preview looks okay, leave the ColorCount-slider at 48
    • if the preview looks too dark or otherwise odd, adjust the ColorCount-slider to a higher value like 96, 128, 216 or 256, but make sure to set it as low as possible
  • then, click the “Create”-button (at the bottom, slightly right of the middle, with a beer glass in it) to generate the GIF
  • then, click on the Save-button (bottom right)
  • in the popup window, type the name you want your GIF to have, set the location where you want it stored and click the Save-button
  • then, browse the Finder to find the GIF’s icon and ALT-click on it
  • first, select “Get Info” from the popup menu and check if the file size is 10MB or less
    • if the file size is over 10MB, go back to GIF Brewery 3, lower at least one of the values you have set there and create an extra version of your GIF that has a file size of 10MB or less
    • as mentioned before, the main values you can adjust are :
      • Length of the clip
      • Scale / Resize (might make the picture more grainy)
      • Frames Per Second / FPS (might make motions less fluent)
      • Color Count (might make the colors less vibrant)
  • then, ALT-click on the GIF’s icon again and select “Open with” from the popup menu and select your internet browser (probably Safari) to preview the animated GIF
  • If you are happy with the end result, you are ready to post the GIF on your social media
    • if not… redo your editing and try again

That’s it !

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 !

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 !

tip : easily make FREE screen recordings in MacOSX

“Screen Recording” means making a video of your screen (i.e. your MacOSX Desktop) while you are using it.

This is a way to make tutorial video’s which you can use to send or give to others, just like the ones you find on YouTube.

(…or you can use this to record online video’s that you can not download)

“Screen Recording” used to be something that would require rather expensive software, but with the introduction of QuickTime X Player in OSX 10.6 Snow Leopard, it’s a simple and completely FREE feature included in MacOSX !

Here’s how to :

– open the “QuickTime Player” application (or maybe it’s called “QuickTime X Player” in your case)

– go to “File” and select “New Screen Recording” from the pulldown menu – or use the key-combo [SHIFT]+[CMD]+[N]

– in the small (shaded) screen that appears, you will see a record-button (with a red dot) in the middle and a grey triangle button on the right

– click on the grey triangle button and you can select your audio input source (e.g. a microphone you’ll be using for your voice-over comments), output video quality and whether you want record your mouse movements and clicks in the video also

– then click on the red-dotted record-button to start recording, but when you do so you will get the option to either select a (static) part of the screen [by dragging the cursor over the area you want to select for recording] or the entire screen [by clicking anywhere on the screen]

– recording will start right away after you’ve made your choice (so do not forget to start talking if you want a voice-over)

– to stop recording, go back to the record-button (which now shows a small black square) and click it

– the recording will stop and it will take a few moments for QuickTime X Player to process it (the longer your recorded, the more time the processing will take)

– the recording will be visible in a QuickTime X Player window right away

– to Save or Share your screen recording, go “File” and choose one of the following :

option 1. “Export” (= normal Save) for saving as a QuickTime .mov-file [you can set the video quality from the “Format” pulldown menu ; either (general) Movie, 480p, 720p or iPhone/iPad/AppleTV ready

option 2. “Export to” to directly upload to a website, import into iTunes or edit in iMovie

option 3. “Share” to directly share your screen recording with your friends through eMail, iMessage (= Apple SMS), AirDrop (= Apple WiFi-filesharing), Facebook, YouTube, Vimeo or Flickr

That’s it ; this might seem rather complicated from these instructions, but it’s actually really simple once you try 😉
