What is the best software to split and join avi files without losing quality (lossless) in Windows?
Without a doubt, VirtualDub is the way to go.
- Open the first AVi in VirtualDub
- Select "Direct Stream Copy" for both video and audio
- In the file menu, choose Append AVI Segment (or similarly named)
- File -> Save As and give your avi a new name
Bingo! I have done this many times. The only gotcha is to be aware that the dimensions, codecs, bitrates, etc. all need to be the same or your new video file will behave, lets say, strangely. Or not at all.
On linux, you can use mencoder:
mencoder -oac copy -ovc copy -o output.avi input1.avi input2.avi
For Windows: Virtualdub. No contest.
Can do lossless splitting and joining to, which is very fast, by doing no re-enconding (but it can then only split on key-frames, obviously, and both parts joined must use the same encoding).
Quality after split is problem, because you must reencoded new file. But it depends on what coded used in AVI file.
- windows only
Avidemux is a very powerful and handy video editing software. It supports all common file types locally. Is's most powerful ability is cutting/joining videos without re-encoding.
