Does encoding from a Quicktime movie reduce PC compatibility?

I'm wondering if encoding from a Quicktime file as opposed to
say, a WMV file, reduces compatibility of the final Flash Video
product with PC's? Does the PC need anything special to view a
Flash movie embeded with a video originally compressed with a
Quicktime codec or once it goes through the Flash Media Encoder is
the original form the video was in irrelevant?
Thanks.

nope, it doesn't matter from which source you encoded your
flv file (at least not for the end user) as soon as the flv has
been encoded everyone with a flash player can watch the video.
Keep in mind that if you targeting a flash player lower then
7 you need to use the sorenson codec, otherwise go for VP6 and you
are good to go
btw, the source can be whatever you want, but keep in mind
that it's not a good practice re-compressing videos

Can I capture a still image from a quicktime movie?

Can I capture a still image from a quicktime movie?

Yes. But how you do it depends on your version of quicktime.
If you have the pro version, you can easily use the "Export" option to output the video as a series of images.
For the basic version of quicktime, or if you want to quickly take make a still image of a single frame, you could just use the "Grab" application in OSX to take a screen shot.

Is it possible to extract a full VR panorama image from a QuickTime movie?

I have created several panoramas - usually 180 to 230 degrees each - and saved them in QuickTime mov format. Is it possible to export/extract the full image from the .mov as a JPG, or TIF(F)using QuickTime Pro or some other program? The QuickTime Viewer does not show the entire image in one shot. As with all virtual reality, the viewer can pan around - up, down, left, right - the image. I want the entire image exported as one piece.
Thanks in advance for your kind assistance.
Rick

I don't know if that software exists. I do know that QuickTime can only export the "frame" currently in the Player window.
Best method to de-construct a QuickTime VR file is with the software that created it.

How does one resize a quicktime movie -

I am trying to resize a Quicktime movie - from 720 pixels wide to 500 pixels wide - height does not matter. This on for a PC - I know how to do it on a Mac. Thanks

To change the dimensions would require the Pro upgrade. Use the Movie properties window to make the change in the width and check the box to maintain aspect ratio.

"Include" options when doing an export to QuickTime Movie in FCE 4?

I've been doing a ton of testing on using keyframe motion with stills (http://discussions.apple.com/thread.jspa?threadID=1646571&tstart=0) so I'm not sure if I've made up what I think happened, or if it's a different option that I'm not seeing.
When I added some text to one of my tests, I did an File > Export > QuickTime Movie. Then under the Save As... dialog box, the Include menu had a whole bunch of options that I had never seen before, with the first few of them starting with the "#" sign, if I'm not mistaken.
Normally I only see "Audio and Video", "Audio Only" and "Video Only". Did I dream this scenario where I thought I saw a whole long list of things in there that, if I remember right, some of them appeared to be like font names? Maybe it was a different app. Like I said, I've been doing a ton of testing. Reason I ask is because whatever it was, in whatever app it was, that was the only test where I was able to produce an output file that does what I want.
Thanks.

don't need this one answered.

Capturing Still Frames from a QuickTime Movie

1. Can I capture still frames from a QT Movie file using QuickTime 7?
2. If not can I do it with QuickTime Pro?
Windows XP

QuickTime Pro can "Export" a still frame to various image formats.
Just position the playhead on the frame you wish to export. Use the right-left arrow keys to "step" through frames.
You can get a larger sized export by enlarging the Player window.

Audio and Video option missing from Export Quicktime Movie Include

Today as I was exporting a clip, I noticed that the Audio and Video option was missing from the Include drop down. I only have the options of Left, Center, Right.
I highlight the sequence, control E (or File>Export>Quicktime Movie) and the Save window comes up. The Settings drop down is the same, the Markers: drop down is the same, but the Include: has the options of Left, Center and Right. I thought the Video and Audio dropdowns were always there. I hate to admit it, but I have not paid attention to them in a while. Getting old I guess.

Thanks, forgot about that.
For what ever reason it started working correctly a couple of hours later, after I started an SD project. The video came out fine
I had been trying out a couple new applications, so maybe one was causing it. I will see if it happens in the future.

Why does a 1.5Gb QuickTime movie file take up 5.8Gb in iDVD?!

I've just converted an old VHS tape to DVD and then used Wondershare DVD Ripper to convert this to a QuickTime movie file (*.mov). This resulting QT file is 1.5Gig in size. When I then add this movie into iDVD, it immediately takes up over 5Gig of project space and thus is too big for a normal 4.7Gig DVD. How can this be? The movie fit on a 4.7Gig DVD to begin with with some room to spare to why does it see so much expansion within iDVD?

CDM -- The Quicktime .mov format is a so-called container format -- and what's inside can be compressed or saved in different ways. So you could have a highly compressed Quicktime file that doesn't take up too much disc space. But, if you want that file on a DVD video disc (that plays on a regular DVD player), it must be in a format and structure that is standardized. MPEG-2 is the DVD standard format, and so it is entirely possible that your highly compressed video won't fit on a standard DVD video disc (in mpeg-2 format).
To bypass the resulting uncertainty with varying compression algorithms, Apple prefers to focus on the duration of videos, They use three methods in iDVD for compressing video into the mpeg-2 standard -- one method for video less than 60 minutes in length (Best Performance) and another for video under 120 minutes (Best Quality); the third method (Pro) takes longer, and tries to optimize the result for video of any length (but still under 120 minutes).
I'd suggest focusing on your video duration. Also, you are likely to obtain better video quality if you minimize the changes to video format -- VHS to DVD is both a conversion of analog to digital as well as a compression to mpeg-2 format. It sounds like you're then converting that into a Quicktime compressed format (mpg4?), and then iDVD is compressing it back into mpeg-2 for the final DVD. If you're editing the video, then you're typically stuck with all those conversions, but there are alteratives if you're not happy with the results (eg, MPEG Streamclip to cut up your DVD footage and Roxio Toast to copy those mpeg-2 files back to a playable DVD).

Does converting from dvd to mpeg4 reduce file size?

Ive searched over and over and cant find the answer to this.
I ripped the DVD Bruce Almighty onto my computer using DVD decrypter. I then converted it using Videora Ipod converter. The ripped file was something like 6.5 gigs. The converted file is only 660MBs. Is this normal ?
Also I have seen it happen opposite, where I downloaded a clip of a diamond store robbery and it started as a 9,791KB Windows Media Audio/Video file and after i converted it, it became a 40,990KB Mpeg-4 Movie file.
Any help or explanation is greatly apreciated
Oh and I watched bruce almight and it worked great, im definately not complaining that it took up less space, just curious of why and if the videora default settings are possibly converting to a smaller bit rate or something that is going to reduce quality when watching on ipod or itunes.

yes thats compleatly normal. You're looking at 3 differant video formats that all compress differantly and efficiantly. The ipod uses Mpeg4 and h.264 which is a more efficiant version of mpeg4. What you have to rememver is when converting from other formats, the video becomes that new format and losses its old compression bit rate (how much data is prossesed per second) and format and gets a new bit rate and new format. Like when I edit video, its done in a format called DV on which 10 minutes of video takes 2 gigs. But the finished product becomes a dvd whichi can fit 1 hour of comparable video in the same space. Let me explain more.
Mpeg2 is the video format of dvds. Mpeg2 is a pretty effiant codec but requires a pretty high but rate to be acceptable. Mpeg4 can do with less data and achieve around the same quality. Also you have to remember that vidora is resizing the video to a lower resolution making the video even smaller.
As for a video getting bigger, thats normal as well. As I said is that the new file will achieve a new bit rate. Mpeg or wmv may need to be reencoded at a higher mpeg 4 bit rate to keep around the same quality of the original video. If you encoded the video at the same bit rate as the old video, youll loose alot of quaity form being double compressed.
All this is hard to explain if you know nothing about video formats and how convertion works. Hope some of this makes sence

Audio missing from imported QuickTime Movie

I imported a mpeg off my cybershot. the audio is loud and clear in iPhoto and again when clicking to play the same file in QuickTime. I was trying to create a smaller file to email and post on the web - imported it to iMovie (iWeb suggests "use iMovie's QT web export settings to reduce file size"). But after importing file, there is no audio. Apple "Help Topics" suggest checking to see if the movie is MPEG Muxed 1 or 2. It in fact is, but there is no further suggestion on how to overcome this problem of no audio in iMovie/QT.
Please help! Thanks!

Hello-
I am trying to download the MPEG Streamclip because I am having the same exact issue as the above poster but when I try to open the download it says that Safari can't open because there is no available application. I'm sure that this is basic but I can't figure it out. Can you please walk me through how to complete this process and convert the files??
Thank you.

Interpreting Video meta data from the Quicktime movie

What is the best encoder for a quicktime movie into iDVD...?

i seem to be having some issues with picture quality once the DVD is actually made... i do have my preferences set at professional quality, but i think my problem may be with the original source file... what's the best format for that...? H264...? mpeg4...? pro res...?
thanks

Since you are just researching, I am going to make this as short and sweet as possible.
The 27 inch screen IMac is your only option. You need to have one with the fastest i7 CPU, fastest Graphics processor. Order one with the base 8 GBs of RAM and add additonal RAM through cheaper third party Mac RAM suppliers.
My preference is for the standard ATA 7200 rpm drives as the Fusion-type drives are not proven technology, yet.
If you want a really fast iMac and can afford it, consider an internal or external solid state drive (SSD) as these drives ard very,very fast.
For external drives fast drives are ones that use USB 3, Thunderbolt and/or FireWire 800 connections.
Stay away from external USB 2.0 external hard drives. They aren't fast enough.
You need an adapter adapter for your mini DV camera.
You are going to need some make of separate high speed audio interface box for instruments and vocals.
Look at interface boxes from M-Audio.
And you'll need to budget for a third party, good quality, high speed external FireWire 400/800 CD/DVD optical drive.
Plus, very seriously consider the purchase of extended 3-year AppleCare Warranty plan.
Something will go wrong with an iMac between 1-5 years.
Three years of warranty protection offers free repairs and replacement of you have hardware failures.
Good Hunting!

Color Shift from Quicktime Movie

Ok, Here is my problem. When I do a copy and paste into director from a Quicktime movie for the first and last frame of my movie the is a noticible color shift when the movie starts to play on my command and when the movie transitions from the last frame of the QT to the still i have placed at the end of the movie.
Any ideas?

My director skills are fairly basic. Any chance you can direct me to an online tutorial that would walk me through this process?
Open your Director file. Locate a QuickTime member in your cast library. Open the Property Inspector and navigate it to the QuickTime tab where you should uncheck DTS. Drag this member onto the stage to create a sprite in channel 1 in an otherwise empty section of your score. Open your Message Window and execute the following lines of code, one at a time, by pressing the RETURN key at the end of each line:
sprite(1).movieTime = 0
updateStage
new(#bitmap).image = (the stage).image.duplicate.crop(sprite(1).rect)
sprite(1).movieTime = sprite(1).member.duration
updateStage
new(#bitmap).image = (the stage).image.duplicate.crop(sprite(1).rect)

Converting from QuickTime movie to AVI

I see a lot of questions about converting from .avi to Quicktime but how do I accomplish a conversion from a Quicktime .mov format to an .avi format?
The reason I ask is because I emailed someone a QuickTime movie and he could not view it and asked for me to send an .avi. I 'think' he's on a PC. Any suggestions? Thanks.

You can use this freeware to make the conversion:
Mpeg StreamClip
or you can buy the QT Pro license and use it. With Pro you open the mov file and use Export in the file menu to make the conversion. More details on using Pro are in the QT 7 guide available here:

How to export still frame from Quicktime movie?

Hello folks
I often need to use a still frame from a quicktime movie as an image file to work with in PhotoShop for windows.
If I export a frame via the export command and choose "Movie to picture" I end up with a .pct file, that Photoshop will not open.
I can open the .pct file with the Quicktime PictureViewer and then export it from that app as i.e. a JPEG-file, but I would like to avoid that extra step and just export a usable file straight from QT.
Anybody know how that can be done?
Best regards
Kris

Same problem here - no matter whether I choose Photo - JPEG or PNG format as the "compressor", QT 7 Pro wants to save with a .pct extension, and changing it to .jpg or .png extension fails to open.
The two workarounds I've found are:
1. Save it in Photo - JPEG or PNG format with a .pct extension, open with Photoshop CS4 or below, save to desired format.
One may be able to accomplish the same using Preview instead of Photoshop, but on my Snow Leopard machine I get the error "The PICT file format is not supported in 64-bit mode. Try selecting "Open in 32 Bit Mode" in the Finder's info window for Preview." and I don't feel like bothering to do this.
2. Use Grab to take a screenshot, copy into Preview, crop as necessary and save to desired format.
Which is easier depends on whether you feel like having to do precision cropping or not. Totally agree with above commenters - whither PICT, Apple?
