setlocal enabledelayedexpansion
SET /A COUNT=1
for /r "F:\coding\Wetlands_1920x1080p\" %%v in (*.yuv) do (
       TAppEncoder.exe -c EBU.cfg -f 30 -i "%%v" -wdt 1920 -hgt 1080 -o !COUNT!.yuv >!COUNT!.txt
  SET /A COUNT+=1
)

Within a block (a parenthesised series of statements) %var% refers to the value of var when the block was parsed. To access the run-time value, you need to invoke delayedexpansion and then use !var! to retrieve the required value.

See any number of SO items on the delayedexpansion problem. (it's very common...)
