Operating systems : Windows, Linux

Split video file by ffmpeg:

There are two ways how to split video files by ffmpeg. The first one is good in itself, more than that - it is faster, but sometimes creates output files with certain flaws. So for those cases there is the second way of splitting video files: it is considerably slower, the output files are bigger, but it seems they are always of the same quality level as input files used.

Way : 1

ffmpeg -ss <start> -t <duration> -i in1.avi -vcodec copy -acodec copy out1.avi

Way : 2

ffmpeg -ss <start> -t <duration> -i in1.avi -sameq out1.avi

- <start> - the beginning of the part of a video ffmpeg is to cut out. Format: 00:00:00 - hours:minutes:seconds - hh:mm:ss

- <duration> - the duration of the part of a video ffmpeg is to cut out. Format: 00:00:00 - hours:minutes:seconds - hh:mm:ss

Examples

ffmpeg -ss 01:19:00 -t 00:05:00 -i in1.avi -vcodec copy -acodec copy out1.avi

ffmpeg -ss 01:19:00 -t 00:05:00 -i in1.avi -sameq out1.avi

- ffmpeg cuts out a part of the video file starting from 1 hour 19 minutes 0 seconds. The duration of the video sequence cut out is 5 minutes 0 seconds.

CSS for a range of elements

 

Styling a range of elements. Here from the 1st to the 3rd one - changing background color. Example:         HTML / XHTML. Code: <div>&nbsp;</div> <div>&nbsp;</div> <div>&nbsp;</div> <div>&nbsp;</div> CSS. Code: div:nth-of-type(-n+3) {background: #f66;} /* Extra CSS, just styling the look: */ div {width: 100%; margin-top: 5px; background: #066;} Note: nth-child may also be used instead.

Renaming files in DOS

 

Renaming files in DOS by REN command REN FILE1.TXT FILE2.TXT - Renames FILE1.TXT into FILE2.TXT REN FILE1.TXT FILE2.HTM - Renames FILE1.TXT into FILE2.HTM REN *.TXT *.HTM - Renames all files with .txt extension into files with .htm extension. Only extensions are changed, the file names proper are left as they were. Since REN is the shorter form of RENAME command, RENAME may be used instead - as more self-explaining may be. Renaming files in DOS by MOVE command MOVE FILE1.TXT FILE2.TXT - Renames FILE1.TXT into FILE2.TXT MOVE FILE1.TXT FILE2.HTM - Renames FILE1.TXT into FILE2.HTM Both methods of file renaming work in Windows command prompt as well. But there is a certain distinction: MS-DOS, other typical / older DOS'es, command prompt of Windows prior to Windows 95 and Windows NT 3.51 use a short filename / 8.3 filename convention. So, for example, REN FILE1.HTM FILE1.HTML is not going to work, there will be "Duplicate file name or file name not found" message. And that is not the case with newer DOS'es or command prompt of newer Windows. It can be not the case in older DOS'es also - if relevant drivers are installed. [ 1 ] MS-DOS 6.0+ tested - but it also may happen to work well under other versions of MS-DOS or other DOS'es.
