| Syntax: |
| frameshots [options] "input file" [output folder] Put quotes around any options that may contain spaces. For instance, if your file name is My Video.avi then make sure you type:

Examples:
frameshots –ms 500 myvideo.mpeg "D:\my videos\"
This takes the video myvideo.mpeg and at every 500 milliseconds, captures a screenshot and saves the thumbnails to "D:\my videos\". |
| |
frameshots –thumbs 20 -width 250 -height 200 -trimthumb D:\vidtest\myvideo.mpeg D:\vidtest\new
This captures 20 screenshots from the movie myvideo.mpeg and saves the thumbnails to D:\vidtest\new. Thumbnails will be 250 pixels wide by 200 pixels tall. Black borders will be trimmed. |
|
|
frameshots –thumbs 10 –skipfront 500 -fileprefix vid_ -filecounter 000 -filesuffix _tn -t -filetype bmp -log logfile.txt D:\vidtest\myvideo.mpeg D:\vidtest\new
This skips the first 500 milliseconds of myvideo.mpeg, then captures 10 screenshots and saves the thumbnails to D:\vidtest\new. Output files will be named vid_myvideo001_tn.bmp vid_myvideo002_tn.bmp etc. |

Advanced Batch File Processing (using .bat files):
| This will make 5 thumbs from every avi file in the current directory: |
| FOR /F %%a IN ('dir *.avi /b') DO frameshots -thumbs 5 "%%a" |
| |
| This calls FrameShots on every avi and mpg file found: |
| FOR "delims=" /F %%a IN ('dir *.avi,*.mpg /b /s') DO frameshots "%%a" "%%~dpa" |
The option /b tells dir to output a 'bare listing' meaning only file names are displayed, no headers or sizes, etc. And the /s is optional, it searches through all subdirectories as well. "%%a" is the file name. And "%%~dpa" specifies to output each image into the same folder the video was found. |
