Some confusion when turn from VFW to CLI encoder.
I used to use VirtualDub + VFW video codec (vp7) + ACM audio codec (ogg) to compress some video clips from MPEG1 to MPEG4 (as I remember, vp7 should be a kind of MPEG4 encoder.)
And When I found the doom9, I learned another way , CLI encoder, and it support HE-AAC audio encoding and MKV container, it feels good.
But, right after that, I lost in the name of many tools' name.
I found I need Avisynth(and, many plugins), all kinds of video/audio decoder and encoder, and MP4Box (i think it's muxer, which merge the video and audio together into a MKV or MP4 file), so I start to think about the work flow of the Movie(not only the video) encoding.
I am making a summary of my understanding, please corrct me if I am wrong.
1: It is needed to separate the video and audio track from the source, DGindex is used in this step
2: It is need to convert the video track to a format that can be accepted by the CLI-AVC(command line video encoder.) Avisynth is used in this step. In my understanding, it's un-compress the source video, which will occupy very very big size. So, it is important that Avisynth will not generate the temp file.
3: Use the CLI-AVC to encode the video track; Use the audio encoder to encode the audio track.
4: Merge the audio and video track into one container, MP4Box/MKVmerge is used in this step.
If the source is a DVD, there is another step, capture the d2v file from DVD, I don't remember the name of the tool......
But, I am still feel confuse
1: about the usage of BeSweet.exe, why we need it?
2: i didn't see the 1st step in MeGUI guide, which tool covered it?
3: What is the role of a YV12 decoder? where we need it? in the step2, de-compress the source, or in the step 3, encoding?
4: I know many dude use scripts/.bat to edcode movie, could you share some to me? I can learn it and make my own one.
