Tutorial to rotate an entire cellphone video 90 degrees in Shotcut freeware

[Arlen Holder]

I snapped a video today which was rotated, where I needed to flip it.
o Looking it up, there were _many_ ways, one of which is shown below.

If you know of a better, easier, more effective rotate, let us know.

How to rotate an entire cellphone video 90 degrees in Shotcut freeware
1. Download & install Shotcut freeware from <http://shotcut.org/download/>
2. Make a copy of a small smartphone test video, e.g., "test1.mp4".
(My test video was about 60 seconds at about 60MB, aka 60,000KB.)
3. Start Shotcut (mine was version 20.07.11) and open the test video:
File > Open File > test1.mp4
4. Make sure "View > Filters" is set & click the "Filters" tab.
5. In the Filters tab, click the "+" icon (aka "Add a filter").
6. Select "Rotate and Scale" & set the "Rotation" field to "90.0 deg".
7. Click the "Export" tab and then the "Export File" tab.
8. Choose a new name, e.g., "test2.mp4" & press the "Save" button.
9. At the top right, a "Jobs" window will show the 0-to-100% progress.
10. Voila! When the job is 100% finished, you have a newly rotated video.

As always, please improve so that all benefit from every action you take.

I simply use 'ffmpeg' - one simple command line. And it's multithreaded
so maxes out all foyr cores on my desktop.

Handbrake (freeware too: Linux, Mac OS, and that crap from WA state),
does it with a simple drop list to select rotation (90° .. 270° in 90°
increments) under "Filters". Also multithreaded. Also has a plethora
of other options (ie: can select ffmpeg to do the huffing and puffing
(not the default)), CLI version too...

the easiest method is to rotate it directly in the video player. no
intermediate conversion needed.

Ah, yes, FFMEPG!
o <https://ffmpeg.org/download.html>
o <https://sourceforge.net/projects/ffmpeg/>

Thanks for that suggestion to use FFMPEG freeware, which also came up on
the Android newsgroups when discussing how to run the conversion on the
smartphone:
o *Android ad free gsf free freeware to rotate a cellphone video by 90 degrees*
<https://groups.google.com/forum/#!topic/comp.mobile.android/ef_YFoctoLA>

Given the US & European patents finally expired, FFMPEG should be
packagable in other apps nowadays, without us having to download it
separately, e.g., for Audacity <https://audacityguide.com/ffmpeg-audacity>.

Looking up the FFMPEG command to rotate 90 degrees, I find it here:
o *How To Rotate Videos Using FFMpeg From Commandline*
<https://ostechnix.com/how-to-rotate-videos-using-ffmpeg-from-commandline/>
o $ ffmpeg -i input.mp4 -vf "transpose=clock" output.mp4
Or...
o $ ffmpeg -i input.mp4 -vf "transpose=1" output.mp4
Where...
o 0 - Rotate by 90 degrees counter-clockwise and flip vertically
o 1 - Rotate by 90 degrees clockwise.
o 2 - Rotate by 90 degrees counter-clockwise.
o 3 - Rotate by 90 degrees clockwise and flip vertically.

Where flipping vertically & horizontally is also scripted:
o *Rotate/flip video with ffmpeg*
<https://duxyng.wordpress.com/2013/04/07/rotateflip-video-with-ffmpeg/>
For example... To Flip video vertically:
o ffmpeg -i INPUT -vf vflip -c:a copy OUTPUT

To Flip video horizontally:
o ffmpeg -i INPUT -vf hflip -c:a copy OUTPUT

To Rotate 90 degrees clockwise:
o ffmpeg -i INPUT -vf transpose=1 -c:a copy OUTPUT

To Rotate 90 degrees counterclockwise:
o ffmpeg -i INPUT -vf transpose=2 -c:a copy OUTPUT

Where there's a snippet of FFMPEG batch commands here:
<https://gist.github.com/cmlewis/f950d876171a11703f89>
o ffmpeg_rotate_90_or_180_degrees.bat
rem For the transpose parameter you can pass:
rem
rem 0 = 90CounterCLockwise and Vertical Flip (default)
rem 1 = 90Clockwise
rem 2 = 90CounterClockwise
rem 3 = 90Clockwise and Vertical Flip
rem
rem To rotate 180 degrees, instead use "transpose=2,transpose=2"
rem
rem Using -codec:a copy will simply copy the audio instead of reencoding
rem
ffmpeg -i in.mp4 -vf "transpose=1" -codec:a copy out.mp4

Ah, Handbrake!
<https://i.postimg.cc/BnmGGmg8/handbrake.jpg>

I had forgotten about C:\software\editor\convert\handbrake, which I used to
use often, which replaced Super when Super went over to the dark side:
<https://handbrake.fr/downloads.php>
<https://github.com/HandBrake>
<https://sourceforge.net/projects/handbrake.mirror/>

While I keep editors and codecs in separate directories...
<https://i.postimg.cc/Wz0vLjWj/editors.jpg>

In my "conversion" directory, are the following from long ago:
o C:\software\editor\convert\avidemux
o C:\software\editor\convert\avisynth
o C:\software\editor\convert\handbrake
o C:\software\editor\convert\oxelon
o C:\software\editor\convert\super
o C:\software\editor\convert\totallyfreeconverter
o C:\software\editor\convert\virtualdub

Note that VLC, FFMPEG, and other "players" & "components" are in a
different locale...e.g., C:\software\editor\codec\...
o C:\software\editor\codec\avicodec
o C:\software\editor\codec\codecinstaller
o C:\software\editor\codec\cole2k
o C:\software\editor\codec\gspot
o C:\software\editor\codec\klite
o C:\software\editor\codec\mediainfo
o C:\software\editor\codec\screencapturecodec
o C:\software\editor\codec\videoinspector

And in C:\software\editor\vid\... as shown in the screenshot above:
o C:\software\editor\vid\adobe_premiere
o C:\software\editor\vid\avisynth
o C:\software\editor\vid\kdenlive
o C:\software\editor\vid\mpc_be
o C:\software\editor\vid\mpc_with_klite
o C:\software\editor\vid\mpc_without_klite
o C:\software\editor\vid\shotcut
o C:\software\editor\vid\videopad
o C:\software\editor\vid\vlc

Thanks for the suggestion of Handbrake, which is not only cross platform,
but which also has a "simpler" method, I'm sure, for 90-degree video
rotation.

Additionally, if a video player does not have a particular desired
feature,
an Avisynth script can do near any video preprocessing,
limited only by CPU ( and eventually GPU ) performance.

While rotating it every time anyone views it will work,
each person has to figure out how to do that on each
platform that is viewing the video.

That's not efficient, IMHO, overall.

Thanks for the suggestion of Avisynth, which I have, but I haven't used it

My log files contain this snippet, which includes avisynth:

o ShotCut freeware pretty much handles everything fantastically

no they don't.

clicking a rotate button is a *lot* easier to figure out and far more
efficient than obtaining a separate app and generating a converted file
every time.

Hi nospam,

I agree that clicking on a rotate button is the easiest, but the
recipient's video player has to have that rotate button, where we have no
idea what video player the recipient will be using (or even what platform
they're on).

Nonetheless, I do agree with you that rotating it in the app, if the app
has that feature, is certainly about as easy as we could hope for.

But I prefer to rotate it so that nobody else has to.

BTW, I realized, only belatedly, there's a problem with my shotcut tutorial
that nobody noticed yet, which is that the resolution, by default, is such
that the resulting rotated video is sometimes "chopped" at the edges.

That's because (apparently) of how Shotcut sets the default resolution
based on the first frame, where some people literally load a JPEG of the
desired resolution as the first frame of the video timeline in Shotcut, but
that's getting more complicated, so I'm going to further explore the
Handbrake, FFMPEG and Avisynth suggestions, all of which I have on my
system, since the goal is the simplest 90-degree rotation on Windows.

Hi nospam,

As always, you fail to comprehend detail that most adults cognate.

For you and for me, it's the easiest.
o But for a little old lady or a ten year old girl, it may not be.

Why is that so hard for you to comprehend?

I was agreeing with you that, if you're technical, like we are, then we
know to use the best players (e.g., VLC or MPC_BE) but a _lot_ of people
use the default players (e.g., Windows Media Player) which may or may not
have the rotate feature.

Rotating it once, and then not worrying about it, is a general purpose
solution that works all the time.

Anyway, I prefer to work on the solutions so let's leave it at that unless
you can find a better solution that works for everyone than Handbrake,
FFMPEG, or Avisynth.

In my browser, maybe only Flash Player videos, I simply right-click on
the video and select "Rotate", to instantly rotate the video 90°.
Clicking "Rotate" multiple times continues rotating in the same
direction.

I guess that's Flash Player only and excludes HTML 5. Too bad. That's
the video format I am actively viewing now, works great. I will check
the CPU usage.

Avisynth is especially efficient for rotating vids and has plenty of
rotation types.

LoadPlugin("c:\Program Files (x86)\AviSynth
2.5\plugins\rotate132\Rotate.dll")
myVidpath = ...

DirectShowSource(myVidpath, audio=true).TurnRight()
or
DirectShowSource(myVidpath, audio=true).Rotate(angle=90.0)
