Questions on MPEGPlayer and JPEG Viewers

Ok, I am currently using Prism Video Converter for this; that's why I asked.

Since WinFF can convert more types of videos than Prism, how do I configure WinFF to create 1:1 video files? I do not need 4:3 videos...

I am also aiming for the highest video and audio quality possible...

Will this parameter be alright?

--- Code: ----ac 2 -acodec libmp3lame -ab 320 -ar 44100 -vcodec mpeg2video -s 128x128 -b 800kb -strict -1 -r 30
--- End code ---

4:3 or 16:9 are the aspect ratios of your videos.

4:3 is the old style non-widescreen TV aspect ratio, 16:9 is widescreen.  If you really selected 1:1 then the video that came out would be completely square.

Select the aspect ratio of the input video you are trying to convert.  If you change an existing video from either 4:3 or 16:9 to 1:1 it will be all squashed in one direction/stretched in the other and look really weird, unless you set up the conversion to chop off the axis that is 'too long', in which case you will miss loads of the video.

Ok, this is something for me to consider. But how about videos that are neither 4:3 or 16:9? How can I find out the aspect ratio for each of my videos?

I am setting my WinFF via this parameter:
-ac 2 -acodec libmp3lame -ab 320 -ar 44100 -vcodec mpeg2video -s 128x128 -b 800kb -strict -1 -r 30
Is this good in terms of preserving the quality of the videos?

Is it also possible to create a playlist of videos for MPEGPLayer to work with?

I am also facing problems using the JPEG viewer. What should I do to ensure that my pictures can be viewed via RockBox?

You should keep the current aspect ratio.  Most video players should tell you the aspect ratio somewhere like properties.

This depends on what you call good quality.  Try them out and see - then you can tweak them.

No, not at the moment.

Make sure they are a)  jpegs (obviously) and b) not progressive jpegs.

darkarn:
1, 2. Ok sure. So far, whatever I am doing do not seem to be affecting the videos' quality.

3. Ah shucks.... But what if I made a Winamp .m3u8 video playlist? *Goes to test it*

4. I can comply with (a) easily... But how about (b)? How do I convert progressive scans to non-progressive scans?
