Please help me convert .lxf files to a more mainstream, less restrictive & more usable format.

I have access to over a 100 commercial grade programs which are about 5 gigs apeice which makes it challenging to post one online as an example or for help purposes.

My need is to make them broadcastable on cable tv. FFMPEG is reported to be a viable option, however I have no knowledge of command lines, ability to create scripts or programming skills. It would be greatly appreciated and very meaningful personally to achieve this goal.

Accordingly, please, is there anyone who would be willing to mentor me and guide me along the path to success?

Desirable mainstream formats for output would include MPEG, MPEG-2 and MP4.

Please volunteer to assist and help me see this through.

Thanks in advance.
