Joining WMV files using AviSynth

[Ramir Gonzales]

Hi,

I've been reading the AviSynth site and wikipage, but didn't find a straight answer.

Is it easy to join 3 WMV files together into 1 big WMV file ?

I've only found info about joining AVI files, but the method to do that doesn't work for WMV files.

Also, is it possible to join everything automatically or do I have to process Video and Audio seperately ? :helpful:

Also, doesn't AviSynth only output to, say, some player ? I would like it to output to disk, so I have the combined file on disk.


Just to add, I tried out Boilsoft AVI/WMV Joiner, but the resulting output had some "jerks" when play was passing over the combined sections. I tried adding 3 15min parts, and around 15min and 30min in the output it started jerking and the last part was completely scrambled. :(

I also tried Windows Movie Maker, but the combined file was way larger than the 3 seperate parts' sizes summed up.

Please, anyone know about a working method ? Thanks a bunch !

First up i probably need to explain what AviSynth is, AviSynth at its simplest level is a frame server it uses scripts to tell it what to do, AviSynth can't actually output any files, it's job is to serve the frames of 1 or more video clips to a program that can output files, so no AviSynth can't output to disc.

The reason your combined files were larger than the 3 individuals is because the bitrate was most likely higher during encoding, thus you will end up with a larger filesize.

If you want a easy solution get MKVToolNix and use MKVmerge to join the 3 WMV's to 1 MKV file, then you can try recompressing with Windows Movie Maker or leave it as a MKV.

Or

You could use AviSynth to join the clips using the same methods described in the wiki for AVI then VirtualDub with This (http://home.comcast.net/~fcchandler/index.html) plugin to open and stream copy a WMV in VirtualDub. Problem here is that VirtualDub will output to a AVI container, you would then need to remux to a WMV/ASF container, try Solveig ASF Multiplexer (http://www.solveigmm.com/?Downloads)

Why do they have to be WMV? Can they be another format?

Thanks a lot !:)
