To save video clip(avi,mpeg, etc), do I need to buy something?

Hi.
I think I missed some information.
I have to save image file,also, I have to record video file as avi or mpeg. Then, I think I need something. Becasue I tried to save avi files with vi example(read and write avi). But it didn't work and it said that needs IMAQ WINDRAW.VI. So I posted this to here. I got that IMAQ WINDRAW.VI. is offered by IMAQ VISION software. So my question is should I buy this software or any software? I know image file saving is possible without IMAQ VISION.But, to record or save video clip, I'm not sure I should buy or not. Let me know this. For your references,My system is consist of IMAQ PCI-1407 and Pulnix camera,IMAQ 2.1, Labview 5.1 and NT as operating system.
Thank you

Let's look at the bigger picture. Why do you want to save video as an AVI or MPEG video? Are you going to do any analysis of the video in LabVIEW? Are you going to be loading the video and replaying it in LabVIEW? What is the goal for creating the video?
If all you are doing is recording video, I wouldn't necessarily use LabVIEW to do it. There are a number of packages that come with firewire boards or other hardware that can record video to these formats quite easily.
If you plan on analyzing the video, you will need the Vision toolkit to do this analysis (or a similar toolkit). I would not use these formats for storing video that will be analyzed, though, because the loss of information due to compression is significant.
The main reason I can see
for using this format is if you are recording video and synchronizing it with other data. I have done a couple of projects like this, but I used the Vision toolkit because I needed some other features it provides.
Without understanding your entire application, I can't provide much more advice.

HT2729 What video formats (avi, MPEG, MOV, etc.) are "playable" on MacBook without adding some kind of converter? Any? how?

What video formats (avi, mpeg, mov, etc.) are "playable" on MacBook without any video converter? Are there any? How come quick time wont let me play a MPEG? When you google this question, al the answers make me download some converter (VLC, etc.)

What video formats (avi, mpeg, mov, etc.) are "playable" on MacBook without any video converter? Are there any?
Depends on what compressed data is in the AVI, MPEG, or MOV file container. E.g., assuming you are using the QT X v10.2 player listed in your hardware profile, a "muxed" MPEG-2/AC3 MPEG file will probably play correctly but an MPEG-2/MP2 or MPEG-2/PCM MPEG file may be problematic. In a similar manner, a Motion-JPEG/WAV AVI file probably won't play the video but play the audio while a DV audio/video AVI file will probably still play correctly.
How come quick time wont let me play a MPEG?
Agian, it depends on what you mean by an MPEG file here. A "muxed" MPEG-2/AC3 file in an MPEG, MPG, TS, or MOV file container should play correctly while the same data in a VOB file container will neither load nor play. Further, this file is not only playback compatible with the QT X v10.2 player but is now conversion compatible to H.264/AAC MOV files on my system which was a surprise to me. On the other hand, if the MPEG file contains MPEG-2 video muxed with MP2 audio (a common PC compression combination), the file will likely have audio/video sync problems and/or freeze up entirely. However, this latter file plays back correctly and without problem in QT 7 with the Apple QT MPEG-2 playback component installed. (For the moment I assume the new support capabilities, as well as, the latest audio problems here may be associated with the system audio upgrades begun in Lion and completed in Moutain Lion.)
When you google this question, al the answers make me download some converter (VLC, etc.)
QT is in the process of being totally re-written. Unfortunately, the addition of new capabilities comes at the expense of making the "new" QT structure less and less compatible with legacy compression formats and file containers and likely signals the eventual end of QT 7 and its "Pro" capabilities in favor of higher definition, more efficient compression technologies.

How do I move my downloaded video clips (from youtube etc) into my photo album so I can see them in the aurasma app?

I want to use videos downloaded from youtube in the AR app Aurasma, but, I don't know how to move the video clips into my photo album to do this.

1 - select the photo(s) in iPhoto and export (file menu ==> export) to a desktop folder - mount the USB drive and drag that folder to it. I usually use the export custom size option to limit teh photo to the maximum pixel dimension of the photo frame letting me have more photos on the USB drive
2 - to restore the iPhoto icon in the dock launch iPhoto from the Applications folder and right click on the icon in the Dock sleecting keep in Dock

Need a camera that saves video clips in a format the iPhone will read

I have a Samsung digital camera and it takes great photos and video clips. The problem is, they don't sync on my iPhone because they must use a different format than .MOV
It's a big enough issue that I would consider buying a new camera. Can anyone recommend a good camera that, once the videos are imported in iPhoto, will then play nice with the iPhone?
Thanks!

Hey OT,
Both the iPhone Quicktime Movie files produced with the File > Export for Web using Quicktime 7 Pro (.m4v and .3gp) play fine on iPhone 4 for me.
Don't have any earlier iPhones handy to test with atm.
That said, the official tech specs do not list that specific file extension as being one iPhone reads: http://support.apple.com/kb/SP587
The .3gp file produced by Quicktime 7 Pro is using the H.264 codec which is supported by iPhone which might be why it still works.
Hope that information is of some use to you

Hello to Kappy, I'm glad I saw your answer. I've been going crazy trying to get some *wmv files to my iPod Touch. Had even purchased 4Media Converter. It said it converted all 3, but only one actually played on my iPod. I downloaded the HandBrake program and got all 3 of my *wmv files converted and onto my iPod Touch in no time flat. And they all played. Thank you, thank you, thank you! Diane

Pages won't let me print, save or export documents and tells me I need to buy I-Work

I purchased Pages and it won't let me print, save or export documents. It keeps telling me I have to buy I-Work because my free trial is over.

You have to delete the iWork trial first. Then install iWork or Pages again.
You cannot completely delete iWork by moving the iWork '09 folder to the Trash. Instead, use Yvan Koenig's script:
          •          Go to http://www.box.com/s/00qnssoyeq2xvc22ra4k
          •          Choose public_YK > for_iWork'09 > other_iWork'09 items
          •          Click on uninstall iWork '09.zip, decompress it, open it in AppleScript Editor and click the Run button

How to Cut, Label, Save sports clips (40Hours, 500GB, 1080p AVCHD Source) for creating season highlight video in Premiere Elements 13?

Thanks in advance for any suggestions you can provide to help me.
I have filmed all of my son's basketball games this season and we are heading into the playoffs soon. I would like to find an efficient way to cut, label, and save video clips to create a highlight movie for the team banquet.
All video is AVCHD and saved on hard drive. A few games were recorded with a Sony camcorder 1920x1980i30(*.mt2s), the rest with my Canon DSLR1920x1080p30(*.mov). I will have about 35 or 40 hours of video by the end of the season. Probably around half a terabyte.
I own licenses to the following video editors.
Sony Vegas Movie Studio HD Platinum 11.
Adobe Premiere Elements 13 that I just purchased bundled with Photoshop Elements 13.
I struggled with burning AVCHD disks with the Sony software, so did the Adobe trial and everything worked great so I bought it.
I went through one game and clipped the highlights, but can't figure out how to label them, or export them as individual highlight files. I guess I would be OK doing this all in a single project if I knew that it would work, and if I could find a way to label the clips so that I can arrange them without having to preview the clip every time.
I am open to using other tools if they don't cost too much, free would be awesome since I don't do this professionally.
Thanks!

GreatFun,
Yes, while I couldn't spend much time today at work reviewing the link ATR provided, at a high level I like ATR's approach as well, and it definitely is advantageous for that use case and rendering only the final product. My use case is a bit different. My son's high school webcasts each match which I then pull off their Youtube channel (with their permission, of course) and use their camera angles and their play-by-play guys commentary (again, with permission) to augment my video (which are closer to the action and much better quality than theirs, I must say). The kids get a kick out of hearing the play-by-play guy yell their name when the score or make a great play. So that is why I produce my clips separately. To me it is cleaner and I can store them for later use outside PE or any other project.
Anyway, regarding the actual shooting of the video. I've been doing this for awhile and there are two elements that are a must for any soccer shoot: a good solid tripod with fluid panning ability, and height. Getting above the action (like atop bleachers), for the most part, is an advantage most of the time. That is why professional sports are shot from above. While I do like to take a few minutes of every game to get on the sidelines and film at field level (this adds a bit of variety to the finished product, and you can't beat the ambient sounds you get when the players grunt and groan), you just can't capture the flow of the game from that angle.
The purpose of your video will dictate your composition. Are you trying to always focus on one player (one particular forward, back, midfielder or keeper) and get their every move (for the purpose of say, college recruitment purposes), regardless of where the ball or action is? If so, you'll want to stay tight on them, but not too tight - know where the action is and use the rule of thirds here with your subject player always in the left or right most third. Let the action, in this case, the ball, enter from the opposite third your player is in to allow the viewer to see a glimpse of what led up to your subject being engaged with the action. If your subject is a keeper, that is the easiest position to focus on of all. When filming just a keeper, I like to set my tripod up along the touch line about 30 yards from the goal line (again, elevated if possible), compose the shot using thirds again so as to let the viewer see the passing action as the goal is attacked. Its great to get a clip of the keeper making a save, but it can be much more impressive and entertaining to a viewer to see how it all unfolds and the choices the goalie has to make to be in the right position to make the save.
If your intent is to film the action where the ball is, regardless of the player or team that has the ball (like most professional sports coverage), it is much better to cast a wide composition. As you mention, it is difficult to find that sweet spot between being too far out and missing the intimacy, or being too close in and simply giving the viewer a headache as the shots zip around as you try and follow the ball. I've found the sweet spot for me is to shoot always keeping a quarter of the pitch in view. This allows for tight enough composition to keep the viewer engaged with the action, without having to jerk the shot around so much as to make them throw up. Soccer is quite fast paced at the high school level and there is quite a bit of "switching the field", where a wing will lob the ball completely across the width of the field to the opposite wing. If you are in too tight, you'll have to pan very quickly to the receiving side, and if done a lot, will not make for very entertaining viewing. There are other examples of why you shouldn't be too tight, but you get the idea.
I've probably written too long a post as it is for this forum, but I hope I've given you some things to consider on your next shoot.
Good health to you!

Cant find conversion program for my windows video clips.

Hi
I recently purchased an Intel iMac as my main desktop PC. I have a little cheap mini DV camcorder which i occasionally filmed my dog on agility course etc. It seems to save the files with a .ASF extension.
The windows media player (on previous desktop win XP home edition) had no problems viewing these and I was able to put clips together to make a mini movie which it was saved with .MSWMM extension.
I have looked through free downloads like perian etc on this site but cant find a mention of .asf or .mswmm extensions that would allow me to view and edit these in iMovie.
I looked at 'MPEG streamclip' which i liked as it allows you to save 'youtube' clips, but that doesnt mention .asf or .mswmm either and i cant find an email address to contact anyone about that on the site i saw it on.
Can anyone tell me what i need to be able to play my existing video clips on my iMac?
Also is there a camcorder out that does automatically saves video clips in a mac compatible format to save me having to convert everything all the time in future?
Thanks
Kati

I've had pretty good luck with Flip4Mac. Here's a blurb about what it will translate (thru Quicktime):
Advanced Systems Format (ASF), Advanced Stream Redirector (ASX) and Audio Video Interleaved (AVI). The plug-in can also handle Windows Media Video (WMV) containers, which have the same roots as ASF. The Microsoft's audio container, Windows Media Audio (WMA) is also supported by this plug-in.
One quick question....you downloaded it, but did you install it? Sorry if that's a dumb question for you, but, for some, it's a reasonable concern.
All that being said, if you're asf isn't playing, possibly it doesn't conform to a standard compatible with F4M. Occasionally I will run across a file that says it's a wmv, but hiding underneath is an unsupported codec, which renders it unplayable on a Mac with F4M, or anything else.
Sometimes VLC will play content that nothing else will.

Looking for Help on How To Save Video as Divx File

Can someone help? I have iMoive 4.0.1 and I need to save video clips as a Divx file. I go to the "share" button and try to compress the clip for Quicktime and choose expert settings. This gives me a list of options including Divx AVI. When I choose this option, the file is turned into an .avi file not a .divx file. ANd there is no other Divx choice available. I have talked to another iMovie user (v4.0.1., too) and--the odd thing--on his option list he has Divx (not Divx AVI). So I need assistance in either finding another way to do this with my existing 4.0.1. or finding a plug-in that will allow me to save as a Divx file. Or--if no one can tell me how to do this--let me ask if anyone out there knows whether iMovie HD 5.0 or iMovie 6.0 would allow me to do what I need to do. Thanks.
PowerBook G4 Mac OS X (10.3.9)

Divx isn't a standard option, so you have downloaded some third party support for Divx. Try the latest version.

Showing Photos While Video Clips Continue to Play

I am trying to fade in photos while a video clip and its sound continue playing. (Although the video clip continues to play, it's obscured by the photo.)
Currently when I place a photo into the storyboard the video clips stop playing, the photo shows, and then the video starts again.
Does anyone know how photos can appear in my movie without interrupting the playing of the video and its audio?
Thanks!

Hi bcas and welcome!
You want to superimpose a still photo on a moving video? No problem!
But you need to buy Quicktime Pro. Here is how to do it (don't worry about the references to video within video, it works the same for stills - you will soon get the hang of it!
Organise the video clips and/or stills that you want to superimpose on to your main video clip, by having these in separate, individual iMovie projects (no matter how small). It helps if these are in the exact length/time you want later.
Now start with the clip in your iMovie project on to which you want to superimpose one of more smaller video clips or stills. Lets call it Main Clip. Export this (share) to Quicktime Pro in DV (full quality). make sure it has the same aspect as before (Quicktime tends to default to 4:3. If you want 16:9, read on).
In Quicktime, with this project open, select File ~ Open File. Select the iMovie file (in your movies folder) of the first clip/still you want superimposed. This will open in its own QT window. Select Edit ~ copy. If it is a movie clip then select all ~ copy (or you will only get one frame!). Switch back to the Main Clip window, and click in the scroll bar where you want the extra clip/still to appear. Choose Edit ~ Add to Movie.
You can repeat this as many times as you like, if you want to build a 'Video Wall', i.e. have several superimposed clips/stills on the same Main Clip.
Do not worry that the new clip overlaps or covers up the Main Clip, at this stage.
Choose Window ~ Show Movie Properties. The Properties Dialogue appears.
You will see a list of video (and audio) tracks. Track one will be the Main Clip, track 2 your new added (superimposed) clip. Click track 2, then click visual settings. From the Scaled Size pop-op menu, choose percent. Then type 50 into the first box. If Preserve Aspect Ratio is turned on you won't need to type 50 into the second box. You have made the pasted footage appear at one quarter its original size. The inset is now hugging the top-left corner of the Main Clip. If you want, you can type numbers into the Offset Boxes to shove it away from that corner (there are 72 pixels to the inch).
If your original Main Clip was required in 16:9, unclick (de-select) Preserve Aspect Ratio, and type in 1920 in the first box, and 1080 in the second, in Video Track 1. This will not affect video track 2, but if that is also wanred in 16:9 repeat for that track.
You can superimpose, 3, 4, or more such 'overlaps' on the same clip, and spend a happy afternoon tapping away for each track in the Offset Boxes until you have got them all in the right place! You can even overlap them, if you can remember (or note down - hire a secretary to take notes) which track you want on top etc.
Save the completed QT file. Import the completed file into a new iMovie project. Import this into the original iMovie project, substituting the old clip you copied to QT as Main Clip for the new fancy clip you have made.
Have fun!

Video clips and animated content works on AC ?

Hi
I have to show a PPT presentation which includes an AVI video clip, but it does not work > black area instead of the video
Another problem when I try to share an application with animated contents (Stellarium, a program that shows stars and constellations on a virtual sky) : it's laggy and dirty on the screen (see the pictures)

My question: is the animated content (video clips, 3D animations etc...) working with Adobe Connect ?
Thanks a lot !

I have the same question regarding the animated content and Adobe Connect.

Whats the best way to import video clips from FCP into a personal template

Hey all, I'm doing some tests. I see some color shifting going on when I export out of FCP using QT conversion (same settings as sequence), Importing into Motion, then adding lower third graphics, then exporting out of Motion .... and finally back to FCP. I put the new graphic added layer on top and have the original on bottom. I toggle the monitor on both layers and see a slight saturation drop on the graphic layer. Has anyone noticed that ?
The reason Im doing this is because lets say I have lower thirds that I want to place throughout a hour show. I want to set-up a basic lower third template and just plug in the video clips for the areas that I need those graphics. It would be way to difficult to export out of the timeline in FCP
and rebuild those lower thirds everytime in Motion. Does anyone know of a better way or does everyone have to export out to the desktop and then into Motion every time they want to use a Motion template.
Thanks to any replies.

Try roundtripping from FCP to Motion and back using Send to Motion. In FCP, Control Click your clip>Send To>Motion Project. The clip will open in Motion with the proper project properties. Make your edits there, press Save, and then render back in FCP. No exporting necessary, although you might see a gamma shift. Much easier.
To do this with an existing Motion template, I'd try copying and pasting in that template's contents once you've sent to Motion from FCP.

To save video clip(avi,mpeg, etc), do I need to buy something?
