Video converting fury (general and C905) |

I have come to a point where I really need to get the facts straight about video containers and codecs. I really really liked M3 for converting movies to watch on my K800 (yes, I can enjoy a feature film on its bright, sharp 2" screen). Importing these movies to my C905 though, I can't get them to play. Instead I have taken to using Super, producing mp4:s with video mpeg4 and audio AAC. The outcome I find inferior to that of M3. Low light scenes are plagued with bad smearing and compression effects.
My first questions deal with containers and codecs. I understand mp4 being one 'container', 3gp another. Is mp4 always superior to 3gp? And what about video codecs? Xvid/Divx are codecs, right? What's the difference? Will SE feature phones play anything encoded with some of these? Or is mpeg4 my best choice here?
My second question is: why will my K800 play files my C905 won't? Using M3, I have always chosen "video codec XviD MPEG4 simple". Meaning what? Is the codec XviD or mpeg4? The audio codec is LC-AAC. The difference from just AAC? Which setting is it the C905 does not like? I use a bitrate of 336 kbps and a framerate of 25 fps.
Well...sigh.

Really? Will it crop 16:9 to 4:3 if desired? |

Will I need to purchase or is the free version enough for converting movies? List of features states free version is limited to 30 secs of "video encoding". |

Simply put, XviD is just the open source variant of DivX (its not a coincidence DivX spelled backwards become XviD). Both are just names of codecs, not names of video formats. The name of the video format both uses is MPEG-4. To some extent, both codecs are exchangable with each other i.e. most videos encoded with XviD can be played in a DivX player and vice versa (compatibility issues may arise if "special" codec settings have been used to encode a video).
Video formats are usually not restricted to any particular container/file format. Container/file formats are on the other hand usually restricted to what video and audio formats they can carry. In generl, it's the video format and not the file/container format that decides the quality level. 3GP is just a simplified version of MP4 and can carry less video and audio formats.
That's all info I could gather on the internet for you. Hope it resolves some of your questions.

With Super, I use mp4, xvid codec, 336Kbps, 25 fps, 320x240, 11:9, high quality.
aac audio.
I seem to get acceptable results. Don't use the "Sony Ericsson 3gp" option if you are - 3gp is a low quality version of MP4 for mobile devices (old mobile devices - before they got powerful)
