W3Exchange / Converting OGG to AVI using direct stream copy -> quality loss?

bagas999 · 2008-06-20 13:08:58

Hi,
I have an OGG video that I want to edit, but unfortunately there is no OGG video editor found for Windows. So I decided to convert the video into AVI using SUPER.

I'm planning to use "direct stream copy" option for both audio and video. The question is:
If I use "direct stream copy", is there any quality loss in the result of conversion?

Thanks in advance.

OGG is a container for a wide variety of video and audio codecs, chapters, attchments etc..
"Stream Copy" may NOT work with every Codec or Container.

However, if successful, there won't be any quality loss

Thanks for the answer.

Just one more question, between two encoder: ffmpeg and MEncoder, which one produces better quality?

they both use the same libavcodec.dll library, which is the encoding/decoding engine.
their difference is not in quality, it is rather in the mode of file opening, parsing and processing.
