slick Guest | @Spin, @Jodoman: This has been tried before, with somewhat disasterous consequences: http://www.advogato.org/article/101.html
Also, it’s possible to find the old version of VirtualDub that’s able to parse ASF. Unfortunately, it barfs on the files generated by the camera.

What we trying to do is actually “put new video into the camera” , not “get it from the camera”. There is no problem converting the ASFfrom the camera to another format.
These cheap little cameras put out some great video. I could watch a movie in my hans while traveling on a plane. A great A/V device for quickie presentations. I want to show my 'old fashioned parents” a few video on their TV. The lithium batteries these days lasts a very long time on the camera. Some are identical to the cell phone batteries you see.
What we need to do is get the following format, encoded exactly (at least for the AipTek Cameras).
Picture size:
- 640x480 or 320x240
Audio:
- Sample Rate = 11.025kHz
- Sample size = 4bit
- Channels = mono
Video:
- Data rate = 1172kbps
- video size = 24bit
- stream = video (Known as ISO MPEG4 v1)
— — — — — — — — — — — — — — — — — — — — — —
From what this thread has come up with, we discovered the following.
* The audio works when encoded with IMA ADPCM format. Very well infact. In most all cases.
* RealMagic MPEG4 encoder, with the AVI-to-ASF DOS converter, (and a few tricks) actually produces a working video that the camnera can play, but has poor quality picture.
* Windows Media Encoder (WME), with a custom profile matching the camera, produces a PERFECT picture. [rename the *.wmv to *.asf] But NO audio at all.
* DIVX and XVID files based on MPEG4 codec can produce an AVI file, when converted with the FourCC software, which is not rejected by the camera. HOWEVER, the camera may only play the first frame, and no audio.

Basically we have either been able to get great audio or a great picture , but not both at the same time.

Entree Rep: 0 Joined: 06 Aug 2005 Posts: 1 OFFLINE | Guys, I played around with the ffmpeg settings in 3gp converter, and got a perfect quality video, but some clicking in the audio, these are the settings i have for the ini file
[Item0]
Title=QVGA•W€‰æŽ¿15fpsƒ‚ƒmƒ‰ƒ‹

as you can see, I set the quality setting to be the same, the size to 640X480, the framerate to 30, and for the audio, i have mono, with a 44Khz sampling rate 16 bit..
but still the clicking... maybe its not so easy to convert mp3 audio to ima adpcm
ps : I d/l and installed and tried more than 10 vid programs today... and then it was there all along

Hmmm.... Did you try the other file posted earlier in this thread?
@ whoisit1998
What is this 3GP? It is all in Japanses and I have no idea what it is supposed to do. I had a 134Mb AVI file and it converted it to a 134MB AVI file.

Jodoman Guest | This whole thing would be much easier if someone could find a version of virtual dub before the year 2000 (version 1.2 or lower perhaps), where microsoft sanctions would not exist bc of a fucking legallity issue. We are so damn close.
The solutions now are to hack XVI32 to change the audio codec in a converted media file, find a multiplexing program that combines ima adpcm audio with iso mpeg 4 v1 video codec, find older versions of virtual dub, or just hack the latest version of virtual dub.
But even if we can do that, im not sure its going to improve sound quality. The sound I have gotten has always been horrible. What am I doing that you guys arent? I convert it with many programs (Sound Forge, DB Music Amp Converter, Sound Recorder) on the settings of the camera, but sound quality does not improve, even when i use different videos. What is the deal?
We are so damn close to getting this camera to become a portable video player, and it just pains me that the next step is going to take a while to solve.
(If you dont want to go to the next step, you can always transfer the audio an mp3 player and watch both separately, like ive already demonstrated earlier in the thread. It could save time for those of us who are less technical and dont like reading 40 page articles on conversion when we just wanna watch a movie)

Wannabe Rep: 0Joined: 07 Aug 2005 Posts: 30 OFFLINE | Help!!! I wish to use my camcorder like a portable movie viewer. It excepts videos using the following - ISO MPEG-4 Video V1 & IMA ADPCM. Now my problem is that I have encoded several video clips with the above codec using windows encoder and they all come out 'weird'. multicoloured blocks appear on the screen instead of images, occassionally I do get images but mostly just seemingly noise.
Anyone know how I can fix this? There is very little info on my cam on the net, there is no software available for it.
More tech specs for my cam are -
10fps 640 x 480
Can anyone help? Im all out of ideas.

Jodoman Guest | The links that spin posted are later versions of virtualdub that dont support asf. Only versions before 1.3D support it. So, naturally, i did a long search for version 1.3C, which DOES support asf. Here is the link

Spin Guest | After hacking an actual video file generated by the camera, HexEdit revealed the letters “XVID”. So now I know the camera uses Xvid.
I tried version 1.3c
and
I used “XviD MPEG-4 Codec”. Very good results!!!!
The file size is a tiny bit larger than I want, but this actually works! The picture is perfect for the most part. I guess there is a REFRESH rate adjustment in there somewhere. The video needs to catch up once in a while to remove expired pixels from previous scenes.
The audio is perfect. I extracted the audio from the video and converted it to IMA ADPCM format, wav fle, and used that as the audio source.
I creatd an AVI file with VDUB 1.3c and renamed it to ASF.
Uploaded file to camera an WOW! It worked. I can live with that, for my own personal viewing, watching movies and stuff. But still not perfected yet for using the camera plugged into a large TV (as a miniature player) for video presentations to impress people. However, with more help here we can figure this out.
No need to change the file with HexEdit or other software like 3gp. VDUB is the last step.
— — — — — — — — — — — — — — — — —
I have no knowledge of what all of the features are for XviD configuration, but I changed a few settings and noticed that the file sized changed a lot (anywhere from 1.5MB to 18MB for the exact same 10 second piece of video). I crashed VDub several times too.

Jodoman Guest | spin:
do you use an aiptek dv4500 camera? That is what i have, and i never seem to get decent audio quality, despite using different programs and content. also, where did you get the xvid codec?

| 07 Aug 2005 03:10 am |
Spin Guest | Jodoman
I have the AipTek IS-DV, but it is the same software as yours.
I got the XVID Codec (Klite mega codec pack) from...
http://home.hccnet.nl/h.edskes/mirror.htm
[Note: I tried DIVX, but it is not nearly as good as XVID]
HERE, download this and see if this (Xvid) video plays on your camera...
http://mysite.verizon.net/vze3nvj6/Blender/video_Aiptek.zip
It won’t play in Windows, unless it is renamed as AVI.

Jodoman Guest | when i rename it to asf, it gives me a file format error on my camera......so you dont use aiptek dv4500?

When you said:
“What we trying to do is actually “put new video into the camera” , not “get it from the camera”. There is no problem converting the ASFfrom the camera to another format."
Yes: I understand this. I probably didn’t make it clear that I was attempting to load the asf files from the unit into my PC, with the aim being to analyse in some way, reproduce the asf from a DVD source clip, and then playback the resulting file on the unit.
Anyway, for those that are interested, I’ve now found my CD-ROM with the Mustek creator software. It’s unbelivably slow and only seems to work about 80% of the time. I think what’s most interesting are the codecs and runtimes that get installed. Perhaps someone could reverse engineer and somehow re-use some of this to figure out exactly how it’s “meant” to be done.

You seem to be on a different page than the other posters. Feed the video files produced by YOUR camera into avicodec (http://avicodec.duby.info) and tell us what the file type (asf or avi? it’s on the “file:" line, after “type:" and fourcc (it’s on the “video:" line, after the aspect ratio (4:3 usually)) are.
>> This whole thing would be much easier if someone could find a version of virtual dub before [microsoft told avery lee to remove asf support from it].
Not so simple! The old Windows Media Tools and NetShow Tools produced asf files in the 'old codecs' (Duck TrueMotion, VDOWave, ClearVideo, Vivo H.263, MS H.263, MS MPEG-4 v1, v2, and v3) and those files CAN be read and converted (to avi) by VirtualDub 1.3c and asftools. After the “bullying incident”, Microsoft seems to have changed the structure of their asf/wmv files somewhat (with the clear intent to keep people from messing with them). Files produced with Windows Media Encoder 7 and 9 with the new codecs (Windows Media Video 7, 8, 9, Windows Media Screen 7 and 9, MS ISO MPEG-4 v1 and v1.1) usually have .wmv extension instead and can NOT be read by virtualdub 1.3c and will produce unreadable avi’s in asftools.
Some people have reported success transcoding from wmv to avi with the newer files with ffmpeg, but I’ve never tried my hand at it, so I don’t know.
To Spin (part deux)
>> My idea is, if the camera can record the ASF (in realtime infact),[...] the PC surely can do the same thing, somehow.
Your pc can do real-time recording/encoding, provided you have some recording device attached to it (a webcam for example).
For example run Windows Media Encoder. In the wizard pick “Capture Audio or Video” and just follow the steps from there. Just as a sidenote, NetShow Tools, Windows Media Tools can do the same tasks in other codecs (in wmv/asf), and VirtualDub and VidCap32 can do it in AVI.

slick Guest | Mustek software now available here:
http://www.megaupload.com/?d=43ACF8QT
It’s just a shy over 34MB.
You’ll need 7-Zip to decompress (the file was a lot smaller with 7-Zip than PKZip, and I’ve only got a slow upstream).
I’ve ripped only the required components (see readme.txt).
