Bets video performance and quality.
Diamond users! Frst I wanted to make a long research thread about the possibilities of video conversion and optimals formats. Instead I'm just gonna tell you which programs work and which video formats are best for my diamond 2 (freshly flashed!)
Use FormatFactory for conversion (google it, it's free!)
You can convert any filefrom any place (iso's and DVD's included) to any other format and setting you want. Good thing is that it's very user friendly and easy to use, and you can insert your own options. Convert any videofile by selecting it, use the options to set it's framarate, screensize and codec, and convert it.
Use Coreplayer 1.2.5 build 4506 (it's the only one that works on my diamond 2, and it's not free)
Or WMPlayer (comes with the phone, but less options and compatibility with file formats)
Here's some pointers on conversion settings without much quality loss.
-In FormatFactory use the "convert to mp4" option. Select any file you want (also from dvd, which gives you some neat options like inserting subtitles and choosing audio language). I've tested mp4 divx and mp4 xvid codecs, as well as AVI and WMV. The last two are bigger in size, and the AVI files run veeeery slow on your phone in coreplayer. WMPlayer doesn't support AVI. I haven't tried MPG conversion, because it is usualy larger in filesize, and the MP4 encoding worked a charm for me, good quality, 18 to 21 frames (human eye can see 21 tops) and small filesize.
-Under settings, you can do whatever you want, just be sure to change the screen size (you can type your desired size) to 800x480, which is widescreen for diamond 2 (largest)
Choose the Xvid Encoder (Divx lags more and is a bit larger. tested on 20 meg DVD rip files, divx came out 13,5 megs in size while Xvid came out 11,2 megs. for any type and size of video the difference in size after conversion is up to 20%!) The H.264 encoder sucks, because coreplayer won't be able to play it smoothly (almost not at all!).
-You can choose to alter the bitrate settings for either video or audio, but I suggest you shrink em down, since my tests resulted in no recognizable loss of quality for extremely different settings. I had a hi-res file with 1600 bitrate and 24 frames p/s, and a lo-res file running only 786 bitrate and 20 frames p/s. No noticeable difference for me, and the size and running of the file was way better than the higher one. My optimal settings thus are:
-20 (frames per second)
For audio I didn't change anything, since it is already set quite low, except for the bitrate, which you could preferably set to 22050 if you want to save a small amount of megs on your storage for a full movie. but 44100 and 48000 are fine too, doesn't differ much in quality audio anyway.
Now all you have to to is press okay in the options screen, and "start" on the mainscreen where the videofile has now appeared, ready to be converted. you might wanna set an output directory for your videofile, but that speaks for itself....
Tell me what you think of the settings and program, and tell me if you found any other (better) settings for running video on diamond 2.
