Using a bat file how to select file from directory for processing if it's of certain type

I'm using the command line interface version of MediaInfo to extract several parameters (to keep the code brief I only show format and duration below) from several hundred small video tutorials to process them for other uses.

I use a .bat file that gathers the parameters, pipes them to a txt file and then opens the file in Notepad:

f:\path\mediainfo.exe "--Inform=Video;%%Format%%\r\n%%Duration/String%%" "tutorial.mp4" > out.txt

sleep 1

start out.txt

As it stands now I have to cut and paste the actual video name into the batch file (file name is "tutorial.mp4" in code above) because I don't know how to programmatically get that parameter into the mediainfo command.

So, my question is, since the video files will always be either .avi or .mp4, is there a way to add some code to the bat file to look for a file in the directory the bat file is in and if it's either of those two types insert the file name into the first line as I have it now? There will only ever be one single video file in the sub directory and it will be either a .avi or a .mp4. It's remotely possible that there might be other file types in the subdirectory so for this reason I can't say "pick the ONLY file in the subdirectory and insert it into the bat file".

I'm wondering if something along this line added to the top of the file:

IF EXIST *.avi || *.mp4

But I don't know if I can use the OR command like that and I don't know how to assign the filename to a variable and how to use that variable in the mediainfo.exe line.....

for %%A in ("C:\folder\*.mp4" "C:\folder\*.avi") Do Echo %%A

To see it work listing ini files in Windows (NB interactively you use %A not %%A in batch). Paste the below.

for %A in (%windir%\*.ini) do Echo %~tA %~aA %A

See for /?.

NB this line does nothing sleep 1. Use Waitfor, timeout, or choice. See each one's help - waitfor /?, etc.
