Converting a Mp4 back into a Wmv

[gundamdbz69]

Long Story short

I had just recently finished a project a while ago. but I had accidently deleted the finished WMV file shortly after converting it into a MP4 with PSP video 9.

Is there any way to convert the MP4 into a WMV? or at least and AVI or MOV???

same process as outlined in this thread
The easiest way is to just turn it into a .avi

use a lossless codec if you need to edit it
choose something else if you just need to distribute it (though chances are that your quality will suffer a lot with the re-encoding)

???

how does modifing a mkv help convert a mp4????

[Kariudo]

write an avisynth script to load the .mp4
load into vdub
save as .avi
???
profit

The point of that thread was making the MKV files usable by opening them with AviSynth. Similarly, just swap out 'MKV' in those examples with 'MP4'. The way both are handled is the same. Open the MP4 with AviSynth using FFVideoSource, use VirtualDub to output to a lossless AVI file, and then give that to your WMV encoder.

As for doing WMV encoding right, the options are pretty much limited to just Microsoft products (unless ffmpeg has magically gained VC-1 encoding capability):
Windows Movie Maker (free)
Windows Media Encoder (just the encoder itself, free)
Expression Encoder (the newest addition, but the downside is that you have to buy it; there is a free trial, though)
