How to rotate a video without re-encoding

Summary: A few tips on video rotation.

If your phone messes up the rotation metadata flag in a video file, download ffmpeg and run the following command:

ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate=0 output.mp4

This should fix the problem without re-encoding the video. If it does not, try setting the rotate switch to a different number, such as 90, 180, or 270. For additional information about video orientation MP4 and other video files, check the See also section.

How to fix slow startup for old Photoshop/Premiere Elements apps (on Windows)

Summary: Easy way to fix slow startup issues for older versions of Adobe products (on Windows).

If you have an older version of Adobe video and photo editing products, such as Photoshop Elements or Premiere Elements, you may be irritated with the long startup time, which could take several minutes. Apparently, the applications try to connect to a server that is no longer in service (btw, excellent job, Adobe!), so they wait... and wait... and wait... The good thing is that there seems to be an easy fix for this.

According to the answer to this post, you just need to add the following entry to your hosts file located in the %WINDIR%\System32\Drivers\Etc folder:

127.0.0.1   static.photoshop.com

This solved the problem form my Photoshop Elements 9 and Premiere Elements 13 instances running on Windows 7 (yeah, I know, need to upgrade to Windows 10, but that's a different story).

Enjoy!
