sort videos by length, need efficiency and if possible reliability

Question

this uses mediainfo to extract video properties and then checks track lengths and sorts the video accordingly to either long or short directories.

as you can see it is very inefficient. can this be reduced to a few lines? also as a side note this track length check is not very reliable since sometimes videos have the wrong track integrated (usually subtitles), meaning the incorrect length of the additional track will determine where the video should go.

this is how mediainfo outputs data to to the vdata file. the video track duration should always be at line 7.

Answer 1

It would be possible to convert the 𝑛 h 𝑛𝑛 min 𝑛𝑛 s convention to an integer by replacing "h", "min", and "s" with their mathematical equivalents using string substitution, then using set /a to math the whole thing into seconds. Once you have that seconds integer, divide by 60 to get minutes.

Also, there's no need to dump the output of mediainfo to a text file. Just capture it with for /f.

@echo off & setlocal

set "video=%~f1"

rem // Change "args" to whatever arguments mediainfo requires.  I don't know its syntax.
for /f "tokens=2*" %%I in (
    'mediainfo args "%video%" ^| findstr /irc:"Duration.*[0-9] [hms]"'
) do if not defined duration set "duration=%%J"

set "duration=%duration: h=*3600%"
set "duration=%duration: min=*60%"
set "duration=%duration: s=%"
set /a "minutes=%duration: =+% / 60"

if %minutes% leq 25 (
    move "%video%" short\
) else (
    move "%video%" long\
)

... or similar.

There's a better tool for scraping the duration of video files, though. ffprobe (a part of the FFmpeg package) will let you get the video's global duration in seconds.microseconds with the following command:

ffprobe -v quiet -show_entries "format=duration" -of csv "filename.mkv"

Output resembles this:

format,5028.080000

As with the mediainfo example above, use a for /f loop to capture the output of ffprobe.

@echo off & setlocal

set "video=%~f1"

for /f "tokens=2 delims=,." %%I in (
    'ffprobe -v quiet -show_entries "format=duration" -of csv "%video%"`
) do set /a "minutes = %%~I / 60"

if %minutes% leq 25 (
    move "%video%" short\
) else (
    move "%video%" long\
)
