Batch Many Video Sizes

[lostfishbait]

File_0.avi - 720x400 - 30fps
File_1.avi - 720x480 - 25fps
File_2.avi - 640x480 - 15fps
File_3.avi - 320x240 - 10fps
File_4.avi - 160x120 - 5fps
---Many more files-----------

I am using x264.exe to encode these files to h264. These video files contain a unknown codec (my best guess), so I have to use --demuxer raw to convert the video file, and when using --demuxer raw you have to tell the video size. This works good if have 3 or 4 video files.

How do I do this for 1000 video files which are all different video sizes?

I want to try using

FOR %%a in ("*.avi") do "x264.exe" -i "%%a" -parameters -o "%%~na.mp4"

but how????

Any suggestions????


Thanks.

Can't you use use ffmpeg to convert? No need to demux then
