need help converting .asf to h264 .mp4

[hydra3333]

Help I'd thought I'd re-engineer an old XP .bat file to convert a bunch of .asf files captured from various crummy old still cameras into .mp4's which will play on my WDTVlive box.

A couple of things go awry -

1. mediainfo can't seem to find/display the framerate from the .asf's so that I can specify it in subsequent commandlines

2. even if I take out any framerate specifying commandline switches, the video's framerate is a lot faster than the audio in the resulting .mp4 - the video plays fast and then stops whilst the rest of the audio keeps playing.

Here's the test .bat

@echo on
call :makeMP4 "T:\CONVERT\homepics\learningtoride.wmv"
pause
exit

:makeMP4
@ECHO ON
SET inpFile=%~1
set outfile=%~1.mp4
set tempmp2=%~1.temp.mp2
set tempmp4=%~1.temp.mp4
set tempavi=%~1.temp.avi
set audiohertz=44100
set audiobitrate=128k
set xvideobitrate=700

I'd try a single direct ffmpeg commandline to do it all-in-one but couldn't figure out how to get the same settings as in the x264 commandline.

Any suggestions, or alternative methods to achieve the same end ?

Have you tried any other batch converters? Like xmedia recode, load all asf, choose mp4 and h264 video. It should be able to keep framerate, aspect ratio, etc.

[hydra3333]

Thank, no I hasn't considered them as yet. I was looking at commandline stuff because these are scattered throughout "organised" folders on a drive, and I could script it easily. If that's the only way then I guess that's it.

Looking at xmedia recode ... can't find the English setting though. Will d/l anyway.

[hydra3333]

Well, xmedia recode seems to work ! Except it resizes the video and I can see its underlying commandline.

gui4ffmpeg doesn't seem to open .asf.
