Hi all,
a couple of weeks ago I started programming a simple but effective way to convert movies in a batch for the Meizu M3 and M6 players. This project has meanwhile become so stable that I would like to mention it here as a general purpose video converter for avi output.
Right now it supports the following devices and specifications, but I am planning to supply other devices as well in the future (message me for specs) :
- Meizu M6 320x240 (rotated) 15-20 fps, up to 512 kbps XviD/DivX avi with mp3 CBR
- Meizu M3 176x128 (not rotated) 15-25 fps, rest as above
but these could work with most of avi-compatible players/PDAs out there already.

Oh, and of course it is free. Uses the also free MEncoder software.
Here's the link to the BatMan Project. It's only for Windows yet (and possibly Linux with WINE).

Highlights are : drag+drop, multilanguage, direct DVD/VOB/ISO ripping, repair problematic videos, sharpening/denoise/colour control, audio normalization, quality profiles, 3-pass, folder processing, custom zoom modes, custom profiles, subtitles.
Supported formats : everything that MEncoder can, and that covers 98% of all videos out there, even .flv
Oh and I might mention that it's kinda idiot-safe just drag a movie onto the icon, choose a quality profile and there you go.

Hi, there has not been any feedback on this here, but I would like to let you know that the latest version of BatMan supports any combination of resolution/fps/rotation to fit any player, making it an efficient converter for every avi-compatible player.

HI
BobbyQ
i have used Batman for my Meizu and have followed your progress on meizume.com - congrats and thanks for all your work.
for the benefit of this forum (and cos i cant remember) can Batman encode using MP2 for the audio.
i ask because Rockchip based devices can play Xvid AVI but audio has to be MP2.
cheers and thanks for all the good work

yes, that is possible by using the special command "switch" and entering "-lavcopts acodec=mp2"

Thanks BobbyQ

Fantastic Bobby !...Easy batch creation with wide parameter selection and the ability to code mp2 or mp3...This is a winner...Thanks very much...

Is there any way to increase audio volume during the encoding process with Batman?

What about cropping, sharpening, brightening,..., without having to first process with VDub?

Thanks again!

Hi jp, audio volume gets normalized automatically to 0.25 of the allowed maximum amplitude, which should make any wishes to further increase volume obsolete, but if you wish you can tweak that by using the special command "switch" and entering "-af volnorm=2:0.7" (with 1.0 it would start clipping too easily).
Cropping is done by overscanning (see help 2.3), sharpen/bright/etc are special commands and get explained in the help as well (invoke by entering "?")

BobbyQ: Thanks for your reply.

For some reason my RockChip player won't play the Batman converted files. All the parameters on the converted file are the same as those converted by AVIConverter except that the writing application with Batman is shown as MEncoder 1.0rc1-3.4.2 and the writing library as MPlayer whereas with AVIConverter the writing application is MEncoder Sherpya-MinGW-20060312 with the writing library as MPlayer. AVIConverter uses ffdshow rather than mencoder.

The file appears to begin to load but nothing plays. The screen is white with the name of the file in the center. It doesn't indicate that the file isn't supported as happens with non recognized file formats.

Any thoughts? Thanks.

Take at least 3 test videos (as different ones as possible), convert them with both programs and check them on your player to be sure it has nothing to do with the source formats.
If none of the BatMan videos play, try converting with the "repair" command. If still none of them play, it would be good to have a small sample video (upload info via PM). I don't own a rockchip player, so I can't test it myself. The "sherpya" message above is nothing of importance, that's just a different build of mencoder with some tweaks that shouldn't matter with your problem.

Thanks for sharing this BobbyQ with us all.

The Meizu community here has been growing.

If you can create one for .AMV video format too that would be great .

the biggest problem is that I don't own a player that can play amv, so I cannot test -> it would be too difficult to do it blindfold.

BobbyQ: Thanks for your suggestions. Still couldn't get it to work. Will PM you test files.

I was able to play an AVIConvert of a non-playing Batman conversion. Go figure?!

in cooperation with jp now .. we might have found a solution for rockchip players. testing and developing right now .. stay tuned
EDIT : the new beta version of BatMan now supports "rockchip-based players" and seems to work in a first test. but it's still experimental and under development.

the new beta now supports both rockchip models, the 320x240 and the 224x176 one.

BobbyQ,

Further to my response here : http://www.mympxplayer.org/viewtopic.php?p=37155#37155

If it helps, I can advise the following settings which work everytime when I use DVD2MP4 converter

For the 2" player (224x176) :

First, select 'XviD' as the Profile.

For Video Size, manually type "224x176" - on my version (4.0.83 build 0178) this size doesn't appear in the drop-down, but manually typing it as I have shown here, works.

Bit Rate - I have found that 512 works 100%.

Frame Rate - at 20FPS, the sound and video remain in sync. Higher FPS ratings result in a slightly smoother video, but the sound lags behind.

Aspect - Auto

Same Quality - False

Audio Codec - MP2 - Important Note! Although Rockchip players handle MP3 Music fantastically, the video audio must be encoded as MP2 it seems.

Bit Rate - 128 works for me everytime.

Sample Rate - 44100 - ditto!

Channels - Stereo

Disable Audio - False
For the 2.4" (also 2.8" and 3" now) Rockchip players, do exactly as above, but select a video size of "320x240"

PLEASE DON'T GET CONFUSED FOLKS - THE ABOVE ARE THE SETTINGS REQUIRED IN THE XILISOFT PRODUCT, NOT BATMAN - I HAVE POSTED THEM HERE TO HELP BOBBYQ FINE TUNE BATMAN
