I offered my daughter a small Sanyo Xacti C6 mp4 camcorder ; and she asked me for a very simple/straightforward recompression tool both for her laptop and/or for her Meizu M6
the 'obvious' tool seems Batman ; now unfortunately as with .mov files in the past ( dunno if its fixed now) , I found that Batman has problems with .mp4 file format
the Sanyo Xacti exports as true standard proof .mp4 file format ; a very simple way to check at a glance is to see if Quicktime can play it , then you know it is standard compliant
so I wanted to recompress the video as 320*240 and either full frame rate (29,97) or possibly only 25fps , no big importance here ; so I used the Custom option in Batman and it turned that whatever the res' setting (320*240 or 640*480) the encoded res' was some weird 'almost' QCIF that is 176*128 !? (instead of 176*144)
the movie res' format is conform to the option selected in Batman ; only the encode res' is wrong here
=> this is poor quality screen video , one fast shot ; indeed a screen capture Snagit ,Camtasia, etc..would give a cleaner screen image ; but this is not the point here; it is enough quality to see what the point is
so hope it helps , since this is some bug to fix ; a minor one I would think (?)
well then all three versions I have would be corrupted...and indeed as seen from the movie files I used here the latest version
earlier versions would even have some frame rate pb ( like you enter 25 and it caps @20) ; this does not happen any more with the latest release
and yes, I have used Batman with some success before
now my question : it might be you have not tried converting true .mp4 files ( not .avi with some mpeg4 codec) did you ?
in the past ( I could try to find the thread but it has been a long time since I had a look @this forum) I had found some kinda similar problem with .mov files ; they would display upside down, etc..
this shot was made to check how a pan on grass would stress the codec ; and by the way the kind of mpeg4 used here is pretty basic , with no B frame for instance ; it is simply a fully 100% compliant .mp4 file in the end , at 3Mbits bit rate ; even ... WMP11 can play it as .mp4 , so !!
on the codec size, one can notice that the QT decoder gives marginally a better picture , with a correct gamma for instance, if one wants to compare with other mpeg4 codecs on the quality decode aspect ; small differences overall anyway ; now this is NOT the point here , the later being that the resolution you enter in Batman will only produce a correct res' window size , while the real encoded res' is faulty ; so this is the point to check ...
What i do to get mp4 and other formats to my meizu m6, i first convert these other formats to divx with the following program: Winnydows: XviD4PSP & GlassBalance: Comments
after that you get a nice divx file, wich batman will not have any trouble with!
I was able to make BatMan convert your video properly by doing the following :
- create plugins\mp4.bat with the following content :
Code:
if %~x1z==.mp4z goto anfang
if %~x1z==.MP4z goto anfang
goto ende
:anfang
echo MPEG4-Visual (.mp4) plugin started.
echo turning off frame rate conversion for ths type of file ..
set avisynth=no
set dsdecode=yes
echo.
:ende
- add call plugins\mp4.bat %CURRENTFILE% to your "plugins\do this before each file.bat"
This will turn off the framerate conversion for your mp4 files.
I would like to add that I do have h.264 (.mp4) files that convert properly without any problem. Must be something with this "mpeg-4 visual" codec your camera is using. Mpeg-4 is a standard, not an implementation.
Do not have much time to investigate further right now.

about your 176*128 problem (which is the resolution of the Meizu M3 by the way) : I don't know what exact settings you have made in Qc, but if I were you, I would use the presets Q0-Q5 and device mode "PC" if you want to convert for your PC, or "Meizu M6" if you want it to be played on your M6.
I have tested it with D=M6, Z=Wide, Q5, and the above plugin, and it is working like a charm.

1) thnx for the 'special' code that solves the pb ; hope you can add it to Batman though in the future since my daughter will surely be a bit reluctant here
2) this is 100% pure Mpeg4 in .mp4 file format ; that's why I uploaded the file to Megaupload so that you can check ; a very simple and straightforward to have some "immediate" idea if an .mp4 IS fully iso compliant is to play it with QT ; the later is some pain as it rejects any .mp4 file that is not 100% compliant but the other side of the coin is that it is useful to check fast
the C6 is almost the same as the CG65 while the later uses of H264 instead of Mpeg4 (!) , well part 2then ; and it does show with some improvement in image quality ; otherwise all these are fully hardware on a chip ala Sony etc.. so 100% ISO compliant
about your 176*128 problem (which is the resolution of the Meizu M3 by the way) : I don't know what exact settings you have made in Qc, but if I were you, I would use the presets Q0-Q5 and device mode "PC" if you want to convert for your PC, or "Meizu M6" if you want it to be played on your M6.
I have tested it with D=M6, Z=Wide, Q5, and the above plugin, and it is working like a charm.
that's why I made this (crap) fast movie; everything is on screen in real time; so nothing special here ; I even did not take full time to check the real pixel value , my guess was 'immediate at a glance' from screen !
it has no big importance here if it was not 128 but 132 , etc.., the point was it is not 240 (as entered in Batman ; such as visible on the movie when I type 320*240 ; and 640*480 in the second case)
I don't get it ...
If you don't tell me what your exact Qc settings and your selected device are, I cannot give you any support. Today I have successfully converted your video with Q5 (and the mp4.bat) : everything is safe and sound.
please watch the movie , even if it is not super quality (!)
still you can monitor in real time all I did ; and so very basically for Qc here a 320*240 size and 29.97fps ; this ends in the anormal size (176*128) you can see for yourself in the movie !
I don't even have it anymore myself , but I can upload it back to my machine with the Megaupload link ; now I am 100% sure it is what is on the movie !
in the second part , you will see I choosed to stay in the original VGA size 640*480 of the movie, thus entering 640*480 in Batman and it turned out , again, the Batman encoded movie is not 640*480 again ; for this second encode I choosed to swap to 25fps and here Batman would output at demanded 25fps frame rate (which was not the case with some earlier version where it would cap @ 20)
as for other parameters (audio) there are pretty standard
my aim is here , once again, to... help ! nothing else ; just as , in the past, when I found some issues here and there , I would report ; just too normal (imho)
so summing up !
Qc =>
1) 320*240 @29,97
2)640*480 @25
in both case the output is wrong size from this Qc setting; such as displayed in the 100% total duration movie for all these operations ; now yes you may have to look closely to the screen , sorry for that crap aspect
now if you tell me that with the source movie I uploaded , and entering the very same Qc parameters as Qc , you get a correct file, then sure there is a problem ! and we would see this , asking other forumers for instance, if ...it is the case
first of all, I still didn't understand all of what you wrote :-/
So here are some tests which I just passed (in each case I used your original SANY0098.MP4 file and the above posted mp4 plugin) :
1. D=M6, Z=Wide, Q5 : all fine. (240x320@20fps)
2. Qc with fps=25, rest Enter : all fine. (240x320@25fps)
3. Qc with fps=29.97, rest Enter : all fine. (240x320@29.97fps)
4. D=PC, Q5 : all fine (480x640@25fps).
--> everything seems to be working as planned. Whatever you are doing there, maybe it is a good idea to download the latest BatMan (2008/03/02), and clean up your /ini folder before doing any further tests. Don't forget to install FFDShow. It may work with any other DirectShow filter, but that's the only one I have testetd and officially support in BatMan.
I used this version, which is the latest available Batman version, if I am not wrong;
and this is the ini folder
>>Don't forget to install FFDShow
indeed ! the version I use (one year old) is indeed not the latest available , but so far I guess there is nothing obsolete in it as for mpeg4 ; only for H264 I will prefer some other options ; if I have time I will however recheck with the latest version available ...hum
1. D=M6, Z=Wide, Q5 : all fine. (240x320@20fps)
2. Qc with fps=25, rest Enter : all fine. (240x320@25fps)
3. Qc with fps=29.97, rest Enter : all fine. (240x320@29.97fps)
4. D=PC, Q5 : all fine (480x640@25fps).
BTW, I notice you refer here to rotated video ( 240*320 , 480*640) , could it be that non rotated option would be a clue ?
or did you mean 320*240 , 640*480 , and it was only some kinda typo here ?
yeah, a typo in case 4. With D=PC, the video was not rotated (default for PC). But I have tested rotated and unrotated with Qc, both worked fine.
And yes, March 3rd is the latest build.
- upgrade your ffdshow to the one on the BatMan homepage.
- delete everything in your ini folder
- install the mp4.bat as explained above
- try with D=PC and Q5 first (use test1 to be faster)
- BatMan does not use the registry for itself. It just modifies the registry entry that turns FFDShow's sharpening filter on and off if you have BatMan's sharpening plugin installed.
- yes, my picture is not flipped - everything is still okay.
Why don't you first try the whole thing on another PC or in a virtual machine ? I guess that will solve your problem if you follow the directions I gave you.
I was able to make BatMan convert your video properly by doing the following :
- create plugins\mp4.bat with the following content :

are you sure here you use DS ? because if I set it to 'no' and use of some intermediate file ( like you do for FLV for instance), then there is no pb ; no image flip, everything is okay ; so ?
did you ?
