Classification and counting of traffic vehicles in avi file

Hi
we are working on a project classification of vehicles and find out count in a avi file 30 sec duration using labview
the algorithm we try is back ground subtraction to dectect vehicle, count vehicles, find areas and classify
can we get a vi

This could be done using Vision Builder for Automated Inspection. If you are interested in it I would suggest looking at the product page found here. You can use this software to implement the algorithm you described in your post.

HI GalaxieMusique,
I'm french too, but I'm going to write this post in english so that everyone may understand it
I have the same problem in Mavericks, but I'd say, more important, with QuickLook.
Indeed Quicklook can't read avi movies anymore. Actually it always been the case, but with Perian we were able to fix it. The problem is that Perian is no longer available for Mac OS 10.9....
I'd assume that our only hope is Apple themselves... It would be nice from Apple to creat an add-on for quicklook to be able to preview the avi movies.
In regards with quicktime, you can download QuickTime 7 here:
http://www.01net.com/telecharger/windows/Multimedia/lecteurs_video_dvd/fiches/10 0.html
and ask all the .avi movies to be played by QuickTime 7 and not QuickTime X (included into Mac OS).
Sorry for the english, we french people can make mistakes sometimes
If anyone has a solution for QuickLook, please do not hesitate. This topic is becoming a real mess....

Differences btween QTX and QT7Pro for trim & merge of avi files

I need to do some trimming and merging of AVI files (DV format).
I have both QTX and QT7Pro installed.
What are the differences between the 2 in terms of features and quality when it comes to trimming and merging of avi files?

QuickTime X has only very basic editing features (trim) and limited export options.
QuickTime Player 7.6.3 Pro is the tool you'll want to use to "join" files and formats.

.avi files and Final Cut Pro/Express

A friend of mine, a PC users, has a Cinemate film to video converter <http://www.moviestuff.tv/c_15.html>, and has digitized some footage for me. He saved it using three different systems: Scenalyzer, Vegas and Pinnacle. Each outputs a .avi file, which he put an a portable USB drive.
The files import into Final Cut (Express), but with this 'warning':
'The following media files are not optimized for Final Cut Express HD.
It is highly recommend that you recapture the media to create new copies of the files to improve their performance for multi-stream playback.'
They seem to playback, and the images 'appear' bring and sharp, so I don't really know what the warning means.
He does have the choice, when he captures, to save the files not as .avi -- his systems default -- but as NTSC DV files.
Would that be the preferred option? Or, put another way, what would be the best format for import into Final Cut Pro or Express?
Thanks,
Hal

<<You may want to invest in a software converter (flip4mac, for example) that will ingest your avi files into FCP.>>
This may turn out to be an option, but it isn't that FCPro won't accept the avi files; it's just that it gave me this warning that I didn't understand. If, as a previous posting said, it's just telling me that this wasn't imported via Final Cut, then 'no big deal'. If it's telling me something else, that's yet to be discovered.
<<If your friend saves the files as DV NTSC, they will still give you that warning when you bring them into FCP. DV NTSC may mean DV stream, which will have to be demuxed (the audio & video are mixed together) and is not easily editable. However, QT pro can demux these files for you.>>
It'll be an interesting 'experiment', and I'll be sure and post the results.
Curiously enough, iMovie imports these same files without blinking, and seems to convert them on the fly as it were to .dv files, with no apparently loss of quality. These can then be imported into FCPro/Express.
<<About the only thing that doesn't give a warning are files captured using FCP ....>>
If that's all it's tell me, that I didn't capture these using FCP, then I guess I could say it's telling me something I already knew. <grin>
Thanks for the input.

.avi files and audio codecs with Quicktime and other software

Apple Mac OSX 10.5.8, Samsung LED TV, Video Camera saving movie files as .avi, audio codec unknown (G-Spot codec is not supported on the mac so I can’t check)
As a well retired non-computer savvy person I am very confused when it comes to talk about different video/audio codecs. I have read so many articles my head is now spinning with information I truly cannot understand.
Using the above hardware, when I play an .avi file direct from my camera onto my new TV I get a perfect picture but the TV tells me “the audio codec is not supported”.
I have tried, using Quicktime Pro and others such as AVCWare Mac Video Converter and Divx converter, to convert the .avi file with unknown audio codec to an .avi using mp3 codec. This is successful but the camera will not play the file and when downloaded onto a flash stick the TV now tells me “not supported file format”. The TV gives me a Divx registration and deactivation code but I am not sure whether this refers to the TV or the flash stick!
To keep things short, all I want to do is edit/crop .avi files from the camera, save with a readable audio codec, put the files into the TV using a burnt DVD or play direct using a flash stick. The TV supports among other video formats Avi, MKV, ASF, MP4, 3GPP and audio being mainly MP3, AC3, LPCM, ADPCM
Hope someone can help please.
Many thanks Robin Welch

Hi George,
Thank you very much for your last post. One small piece of information from you regarding frame size was the final part to my jigsaw. I recently purchased a new digital camcorder and LED TV and getting them to talk to each other has taken me since December! Having installed MediaInfo as you suggested, I found the camera saved the .avi files with AAC LC audio codec (first piece of the jigsaw). Talking to the people at DivX about the problem brought up the fact that both my TV and Sony Home Theatre should be registered to play DivX files, this I did (second piece). Having reinstalled Perian and opening my .avi files in Quicktime player I tried saving the files as DivX to several profile options including Home Theatre with max 720 pixels (last piece). At last it works fine. Thank you for your help, I am very grateful.

How do I move AVI files from iPhoto to an AVI player app?

I have transferred some files from an SD card on to my iPad. They're stored as AVI files in iPhoto but I can't get them to play. I've downloaded an app called Playable which can play AVI but don't know how to transfer the files in to the app.

Are you able to play them? If not and the fact that the Show File gets you nowhere indicates that those video files are missing from the hard drive. Download Find Any File and search for one of the avi files by full name including extension.

Avi file does not have the same resolution as image file?

I'm using LabView with an IEEE-1394 camera and I set up the camera to record at a resolution of 1280 x 960 and can snap images and save them at that resolution from Measurement and Automation Explorer, but when I record avis using LabView, they have a resolution of 720 x 480 even though the images being written to the avi are 1280 x 960. I have had this same problem trying to make new videos from the original in which I extract a part of the image and write it to a new avi file... even though the extracted image is something like 620 x 300, when I play the avi (or get avi info), it says the avi has resolution of 720 x 480. I've tried creating an IMAQ, then using the set image size sub-VI to set the image to the size I want and the image shows up with the right resolution but the resulting avi has the wrong resolution, so my sub-videos are distorted. Is there some way to set the resolution of the avi other than by writing an image of that resolution? I'm using the compression filter DV Video Encoder... would that make any difference?
Thanks!
Kelly

Hey Kelly,
As far as the different codecs that are available, it all depends on what type of filter you want to use. They vary so widely that it is hard to say that one is better than another. Also, it depends on what type of compression that you want to use will also determine which codec you will want. Some use lossy compression and some use lossless compression. With lossy, you will lose some data when it compresses, but lossless will not. Lossless on the other hand will produce large data files, as it can only compress a certain amount without losing data.
One thing that you might want to consider is using some of the Vision functions to track changes in pixel values from one image to the next. There are a lot of different processing that you can do on your images before you store them to file by using the NI Vision functions. Other than that, you might have to just play around with the different codecs to find which one will work best for you.
Let me know if you have any further questions or concerns. Thanks, and have a great day.
Regards,
DJ L.

Loading AVI file. into Elements 8

I am using Primier Elements 8 on a PC running Vista. I am trying to load and edit a 1.9 G AVI file that contains video and audio in Elements 8. When I load the file into Elements I get a video track that has the video but the audio track that does not have any audio. Any idea as to what is causing the problem and what I need to do to fix it?
Thanks

Final cut 604 won't let me import dv avi files

i just get file error, denied 0 recognized, unknown messages when
i try to bring them in.
these are straight dv avi files. qtplayer opens and plays them fine.
i tried changing permissions so everybody can access them. no luck.
the project is a dv project so there shouldn't be anything wrong
there. what have i overlooked?
i can also batch convert them using mpeg streamclip to qt dv files
and they work fine.
shouldn't avi files import into fcp without issue as long as they're
standard dv within the container?
i emailed a couple of the short ones to a friend who's on fcp 5 and
osx 10.4.11. i'm on fcp 6.0.4 and 10.5.x. he was able to load them into
fcp without issue.
thanks,
BabaG

You can use [MPEG Streamclip|http://www.squared5.com] to batch process the files.
As Jerry suggested, export them to QuickTime and choose the DV codec at 100% quality.

Problem with importing a AVI file

Hi everyone,
I did a capture to hard drive of a VHS home movie via Turtle Beach PCI card software, saving as .avi file that is roughly 2 hrs long, when I import into Premier Pro CS3, I only see the first 2 minutes. Anyone have a suggestions on what I can do to.
Thanks,
George

George,
I just finished a project, similar to yours and used the same hardware, TB PCI, and their software for the Capture. In my case, I chose AVI uncompressed and every file Imported into Premiere fine. Do you recall which CODEC you selected in the TB software. The only problem with AVI uncompressed is very, very large file sizes and I had 32 VHS tapes, some EP and some LP.
Quite a few folk on this forum have had excellent results with the Canopus products, but I already had the TB, so I did not change.
If G-Spot throws a fit, then you probably have a corrupt file. I assume that G-Spot installed OK, and the errors were with your AVI file. If not, try install again with all AV, Spyware, etc. software turned off. Try to Capture again with AVI uncompressed and see if your result is different.

QT does not open AVI file

hello,
I have installed Perian but with Mountain Lion QT does not open AVI file (no audio and no video)
do you have any suggestion?

I am using QT pre-installed in Mountain (should be X)
QT X can only play files using codecs it is programmed to expect to be used in the loaded file container/with the loaded file's stated extension. For example, QT X will not play a "muxed" MPEG-2/AC3 file with an MOV or VOB file extension but will usually play the file if the extension is changed to TS, MPG, or MPEG. On the other hand, the QT 7 Player tends to look at the internal header information and select a codec based on what the file says it needs for the actual playback. Thus, the QT 7 Player may frequently play files that the QT X Player does not play.
Besides supporting the the AVI file container, your QT system must also be configured to support the actual audio and video codecs contained in the AVI file and not have a "conflict" problem. For instance, Motion JPEG support for QT was dropped with the release of Lion. AVI files containing MJPEG video thay plays correctly under Snow Leopard will no longer play under Lion or Mountain Lion with additional support. In this case, Perian still provides such support. It also still provides support for DIVX, XVID, 3IVX, and similar third-party codecs commonly found in AVI containers. However, Perian support for such files can become conflicted if you have also installed the actual third-party codecs along with Perian and the different codecs fight over which is to be used for playback. This is why it is important to know the actual codecs used to create files using generic file containers like AVI and MOV and the codec components actually installed on your system, as well as, their potential for creating conflicts.
As to the actual playback of files, there are basically only three options (as indicated by the URL provided above:
1) You can conform the file and/or your system codec component configuration to play your files using a QT player app if possible,
2) You can use an alternative media player app the contains "native" support for the file containera and/or codecs used to create the files, or
3) You can convert the file to a compression format and file container that that is already natively supported by QT-based applications.
Since do not seem to know or are unwilling to identify the specific codecs causing a problem here, the only workflows left to you would be to try playing the file in an alternative media player which contains its own built-in codec support (e.g., VLC) or convert the files to something your current QT system configuration can handle (e.g., use a converter with built-in codec support like HandBrake).

Generate AVI files. Convert in AVI from MOV. QUICKTIME PRO??

Hi,
First of all, I'd like to ask you an apology if my problem has been solved in another post, but I couldn't find it.
I have an AVI file and I’d like to add the subs (srt file) My idea was to open the AVI file with a program, to add the file and finally to generate a new AVI file with the subs included.
I had the wrong idea that with Quicktime I could make that, but after several intentions I have realized that I haven’t the Quicktime Pro, what I have is Quicktime X and with this version is not possible to generate an AVI file the way I need.
I have read a few posts about the differences between Quicktime 7 Pro and Quicktime X, and before thinking in buy the Quicktime 7 Pro license, I want to know if it will make what I want.
I also need to convert a MOV file into an AVI file or another smaller which I could share by email. I prefer AVI format because all users (MAC & WINDOWS) can play it.
I am not sure if the Quicktime 7 Pro is the better solution for me. Maybe you know another program which I can get what I need.
Thank you in advance, best regards.

If you are also running the 3ivX codec module and the movie is a DivX AVI, then you you may need to run the file through 3ivX's DivX Doctor II. This utility updates DivX .avi videos to 3ivX QT (.mov) videos. (This assumes other files still play correctly with audio.)

"After the conversion you will be able to play the video smoothly, and the audio glitches inherent in the AVI format will be fixed" -- according to the 3ivX site.

AVI files wont encode

I'm working on a project that requires me to capture video from 3/4 inch analogue tape. Some of the project was shot on DV format and was in raw form. Here's my work flow.
I'm taking my 3/4" analogue tape and loop it through a dv deck (to make it digital) and into my apple G5 by firewire from the dv deck. I edit my piece out and and export it out as an AVI file. I adjust the AVI compression video setting to "none" and export it out to a server.
From this server our IT dept. takes it and encodes to the file type they want along with the settings for streaming. BUT some of the files they cannot encode.
It seems that the pieces that were edited from the raw DV tape were able to be encoded...and only SOME of the 3/4" pieces were able to be formated. Others give an error.
I'll post the error message here:
\videos\ProfessionalTechnicalEd\HumanSvcs\MarieR\New\Terminology
Error: 0xC00D1B83 - One or more codecs required to open this content could not be found.
C:\Program Files\Windows Media Components\Encoder>Pause
Press any key to continue . . .
Has anyone had this same issue and does anyone have a solution for getting these encoded from an AVI file.

I often need to make files in FCP that Windows Media Encoder can read for transcoding to WM#. My workflow from a dv sequence is:
1) "Export Using Quicktime Conversion"
2) Format: "AVI"
3) "Options..."
4) "Settings..."
5) Compression type: "DV/DVC PRO - NTSC"
6) Motion
a) Frames per second either 29.97 or "Best"
b) no "Key frame every" set (dv has no keyframes)
c) no "Limit data rate to" set (dv has its inherent own data rate)
7) Compressor
a) Quality "Best"
b) Scan Mode "Interlaced" (windows media encoder has its own de-interlacer)
c) Aspect Ratio "4:3" (I let windows media encoder do the aspect ratio correction depending on the final use)
This work flow just repackages the dv file in fcp into a dv encoded AVI with no re-compression.
The "uncompressed" option you describe basically gets you no advantage, its just a huge file.
There also could be problems with the audio that is causing windows media encoder to choke.
As an aside windows media encoder does its own "color correction" so you need to color correct your original fcp sequence to a full range sequence otherwise windows media encoder will make it really flat.

How to export/watch .avi files using Quicktime Pro

Hi there.
I've got Quicktime Pro and I'm trying to convert .avi files so I can play them on my iPhone. I open up the .avi file in Quicktime and then slect the Movie to iPhone option.
It will take about 20 mins or so, but when I open the file all I get is a white screen even though the timer is showing that the movie is playing.
I can't even watch .avi files using Quicktime as all I get is a black screen.
Could someone please help?
Thanks

Thanks, but unfortuntately that didnt work. MPEG Streamclip couldn't play any of the .avi files, it still came up with a white screen while playing.
I tried this with a number of .avi files but I had the same problem.

Maverick unable to play avi files

i updated my Mac Pro today to mavericks and now i can't view avi files or anything other than mp4 with quick view, using the space bar. need help

The best way to solve this problem is by downloading VLC media player. You will find problem even installing Perian or QuickTime 7 because many videos will not play in these media player. So to solve this problem download VLC from "http://www.videolan.org/vlc/download-macosx.html"
