echo =======================================================
echo      8K VR 智能合并 (当前文件夹名 + 自动增加 _merge)

:: 3. 取名逻辑：直接获取当前文件夹的名称
for %%I in ("%cd%") do set "suggested_name=%%~nxI"

:: 4. 用户确认
echo 建议名称(当前文件夹名): [ !suggested_name! ]
set "user_input="
set /p "user_input=直接回车使用建议名，或手动输入: "
if "!user_input!"=="" (set "final_name=!suggested_name!") else (set "final_name=!user_input!")

:: --- 核心修改：统一增加 _merge 后缀 ---
set "final_name=!final_name!_merge"
:: ------------------------------------

:: 5. 路径与合并逻辑
set "current_drive=%~d0"
if /i "%current_drive%"=="D:" (
    set "output_path=!final_name!.mp4"
    set "is_nas=0"
