Edit .arf recording

I did a .arf recording using WebEx Recorder. I would like to remove the first minute of the recording.

Tried doing it using WebEx Recorder but it turns out that it only edits .wrf files.

Then I found this link which pointed to an Article, which unfortunately is a broken link.

https://communities.cisco.com/message/82281

Can someone please help me with this. If I need some converters to convert it to another format would appreciate if you could point me to some free software which could do that.

The size of the .arf file is around 50MB and it is a 12 minute recording.

Thank You

Do you have access to the Webex converter? If so, convert it to MP4, then use the open source ffmpeg to demux the audio stream. The resulting audio stream can be edited with another open source package (Audacity).

Thank you for your response.

I have converted the .arf file to .mp4. The resultant mp4 has both audio and video.

I had a look at ffmeg, it seems to have the ability to convert files to another format (for instance to .avi). How can I use this capability to cut some part of the mp4 video?

You should be able to convert a .arf to Windows Media Video format using WebEx Recorder.

Windows Media Video format can be easily converted to .mp4 or edited directly using Microsoft Movie Maker.

I can convert arf to wmv but the audio is always out of sync and video resolution degrades. I'm betting Cisco can fix it but doesn't so people are forced to use WebEx.

Any ideas to convert arf to wmv without lowering quality?
