如何在dos批处理文件中删除一系列字符以生成文件名

我制作了一个批处理文件，用于使用 ffmpeg 拖放转换视频。我使用 avisynth 脚本“avs”作为输入。生成的视频是“我的视频文件.avs.mp4” 如何使生成的视频文件名成为“我的视频文件.mp4”？这是我的批次：

@echo off
title Converting video for mobile phone... by xXx
ffmpeg.exe -y -i %1 -f mp4 -vcodec libxvid -b 150k -r 25 -maxrate 150k -bt 1k -bufsize 4M -acodec libfaac -ac 1 -ab 32 -ar 22050 -vol 20 -aspect 4:3 %1.mp4
title Finished!!! Press any key to close the window
echo.
echo.
echo.
echo "Success... press any key to close the window."
pause > nul

提前致谢！

I've made a batch file for drag and drop conversion of video using ffmpeg.
I'm using avisynth script "avs" as input.
The generated video is "my video file.avs.mp4"
How can i make the generated video filename to be "my video file.mp4" ?
here is my batch:

@echo off
title Converting video for mobile phone... by xXx
ffmpeg.exe -y -i %1 -f mp4 -vcodec libxvid -b 150k -r 25 -maxrate 150k -bt 1k -bufsize 4M -acodec libfaac -ac 1 -ab 32 -ar 22050 -vol 20 -aspect 4:3 %1.mp4
title Finished!!! Press any key to close the window
echo.
echo.
echo.
echo "Success... press any key to close the window."
pause > nul

Thanks in advance!
