I am new to video editing, & either can't save the output file, or other applications can't read it correctly.
I have a number of video clips taken with a Canon A510 camera on its side.  Windows Media Player plays them on their side.
I want to rotate the video clip, save the rotated version & burn it on a disk & send it to someone who will probably play it on a DVD/CD player, possibly on a reasonably old laptop running WIN 2000.
I have downloaded Super from your site, opened Super & put a copy of one of these avi files in the box at the bottom.  I then open the analysis box & it shows -

I select output container avi, output video codec M-JPEG, output audio codec ADPCM microsoft, video scale (& aspect) no change, frame/sec 15, & it does not offer a bit rate of 2684 so I choose 2688, audio sampling Freq 11025, 1 channel which only allows a bitrate of 6 kbps whereas the original has a rate of 88 kbps.
In player options I choose full screen, aspect 4:3, turn right.  I right click & in Output File Saving Management I choose a folder & replace spaces with underscores, & save changes.  I then choose encode, & I notice the output file is slightly smaller than the input.  When I play last rendered file Super plays it with the revised orientation.  The input file was Test MFW.AVI, the output is Test_MFW.AVI.AVI.  If in Windows Explorer I double click this Windoews Media Player tells me "A codec is required to play this file. To determine if this codec is available to download from the Web, click Web Help."  I chose the default MEncoder option for this test.
