Fade-in / Fade-out using FFMPEG

The following examples show how you can use FFMPEG to do fade-in fade-out for audio and/or video.

ffmpeg -i input.mp4 -vf “fade=t=in:st=0:d=10,fade=t=out:st=10:d=5” -c:a copy output.mp4

The example above applies both fade-in and fade-out effects for video, but not for audio.

ffmpeg -i input.mp4 -af “afade=t=in:st=0:d=5” -c:v copy output.mp4

The example above applies fade-in effect for audio, but not for video. The parameters are pretty much self explanatory. A combination of different parameters can be used to meet your editing requirements.

Install Windows on USB Flash Drive or External Hard Drive

AOMEI Partition Assistant

You probably have heard of Windows 8 to Go, which allows you install a portable version of Windows 8 on a Microsoft certified USB flash drive. If you are addicted to the old operating system (OS) Windows 7, you may wonder is there a way to install Windows 7 on USB removable storage device?

With Windows 7 on a USB flash drive or external hard drive, you can take it with you wherever you go and run Windows7 on any PC.

Windows Setup can detect USB hard drive, but when you select the external drive as the target location to install Windows 10/8/7, you will get the error “Windows cannot be installed to this disk”. Luckily, there is a workaround for this, and it is quite simple. Even those who does not know how to install Windows from a USB drive can follow this guide to get it done. (read the whole story)

How to delete large folders super fast

The two commands that users require are Del, for deleting files, and Rmdir, for removing directories.

  • Tap on the Windows-key, type cmd.exe and select the result to load the command prompt.
  • Navigate to the folder that you want to delete (with all its files and subfolders). Use cd path, e.g. cd o:\backups\test\ to do so.
  • The command DEL /F/Q/S *.* > NUL deletes all files in that folder structure, and omits the output which improves the process further.
  • Use cd.. to navigate to the parent folder afterwards.
  • Run the command RMDIR /Q/S foldername to delete the folder and all of its subfolders.

The commands may require some explanation.

DEL /F/Q/S *.* > NUL

  • /F — forces the deletion of read-only files.
  • /Q — enables quiet mode. You are not ask if it is ok to delete files (if you don’t use this, you are asked for any file in the folder).
  • /S — runs the command on all files in any folder under the selected structure.
  • *.* — delete all files.
  • > NUL — disables console output. This improves the process further, shaving off about one quarter of the processing time off of the console command.

RMDIR /Q/S foldername

  • /Q — Quiet mode, won’t prompt for confirmation to delete folders.
  • /S — Run the operation on all folders of the selected path.
  • foldername — The absolute path or relative folder name, e.g. o:/backup/test1 or test1

Overlay Videos

You can try the following if you would like to overlay a video onto a master (background) video, without re-encoding.

ffmpeg.exe -i master_video.mp4 -vf “movie=smaller_inner_video.mp4[inner];[in][inner] overlay=70:70 [out]” completed.mp4

where 70:70 in this example are the positions that you would like the smaller video to be overlaid onto the master.
