Gamma and Exporting thru Quicktime

Apparently, when you export thru Quicktime, it modifies the gamma according to the codec used. How can I have a consistent gamma when importing-exporting UNCOMPRESSED 1920-1080 @23.98 image sequences?

Hi John,
the uploading to .mac usually uses a sorenson codec in a .mov container.
That can be watched on PC just when the free Quicktime Player for Windows is installed. does your friends have done that...?
It tells them they're missing some compressor. Downloading the newest version of QT does not help either. newest version for PC or on your Mac's side?
QT7 offers now the brandnew h.264 compression codec... this isn't supported on the Windows side yet (just experimental/beta)... so using the "latest" is maybe the wrong way...
in the iM export dialog you'll find the option ".avi" (PC container + sorenson codec) try that for a mail (big files!) and your friends should see your movie...
and tell them, they shall buy a Mac, hey, c'mon!
you can offer downloads of your project on .mac, but not as convenient as the "upload to" function. ... but that is another cup of tea......

General error in FCP re: rendering and export after Quicktime 7.5.5 update

Hi
My FCP 6.0.4 rendering and export to Compressor no longer works after an update to Quicktime 7.5.5.
Rendering fails after a few seconds "General Error!" pops up. Exporting to Compressor, after setting it compressing, Compressor after a few seconds fails. (audio is processed) My current work around is exporting a sequence using Quicktime conversion (time consuming) and then opening in Compressor.
I've done the usual, deleting prefs, new sequences and projects, even saving movs in different codecs.
(been using H.264)
My sequences are all custom sizes but tests using presets also fail.
Any ideas anyone?
And I was so happy the Quicktime upgrade could play sequence movs recorded months earlier that until now I couldn't play properly due to previous Quicktime upgrades!
Apple gives with one hand and takes with the other....

Hi There,
Thanks for your reply on this.
Well basically since I'm using content already in the H.254 codec (eg: a trailer off the internet, or the downsizing of HD footage) i'm just exporting to a codec that didn't have to be rendered and gave quality results. I used motion jpeg B as an export codec because it was quick (although HD space hungry) with no drop in quality. The resulting exports could be imported into a custom sequence (720 x 405) as square pixel aspect ratio files. Overlapping the canvas with other windows (eg: viewer) meant I could play a clip (with dropped frames) but not have to render it. I selected the H.264 codec as the sequence codec because I've found other codecs introduce darkening or lightening or blurring or other undesirable artefacts when exported to Compressor. H.264 used in the sequence settings exported through Compressor would give resulting m2v's as sharp and contrast accurate as the source file.
That was until the recent 7.5.5 Quicktime update where attempts to do the same things I did before result in "General Error!" coming up after a few seconds of play or rendering.
Traditional DV codecs are "blurry" in my opinion, especially when coping with web content or conversion of HD downloads.
If you can suggest an editing codec that works best with FCP that is quick, doesn't introduce blurring or general degrading of the image I'd be happy to try it out. I typically downsize HD content from the web for DVD playback, so it's usually in a H.264 codec already. So i would need a codec for export from Quicktime that would work best with a codec in FCP. That doesn't alter picture quality when compressed to m2v in Compressor.
Thanks!

Difference between Export as Quicktime and Export as Quicktime Conversion

If the desired end result is a Quicktime file, compressed with the default h.264 "for broadband" preset, should there be any difference between:
1) exporting a sequence with "Export as Quicktime", then opening up that file in Quicktime Pro and compressing it with the preset.
or
2) exporting the sequence with "Export as Quicktime conversion" with the preset.
I had expected these to be equivalent, but I've found that method #2 gives me dramatically sharper text in titles. Can anyone explain why? I'm using FCE 4.

Well I reckon it's because you are crunching numbers twice, in #2 it's once.
Despite digital transfers being said to Lossless, I call it Lessloss.

How do I import a video in mp4 and export in QuickTime H.264?

Or is that even possible? Whenever I try I get a error "Incompatible codec..."

It's one file that was produced in a different video software that I used before purchasing Premiere Pro.
Most of it is composed of a series of stills, though there is a portion that is video (mp4 from the old software). I'm assuming I might have better luck creating a new video and exporting it in that format by importing the stills and video and working with them in Premiere Pro.

2 basic questions/ viewing clips and exporting to quicktime

I have to problems thus far. 1stly, I'd like to figure if I can utilize the playback feature for more than one clip at a time. Whenever I try to use it, it only plays one clip then stops at the end, though i'd prefer it continue on through the transition into the next clip.
2ndly, I've exported the clip into a quicktime file and uploaded it to my .mac account. People using apples can view it, but window's users cannot. NOr can they view it when I export it to a full size .mov and just email it to them. It tells them they're missing some compressor. Downloading the newest version of QT does not help either.
Any help in either or both of these matters is greatly appreciated.

Cannot load movie with subtitles and export in QuickTime 10 / Os X Lion

Since Os X Lion, when trying to load a movie (DivX) in QuickTime 10 at the same time that the related subtitles file (.srt) is in the same folder as the movie, QT 10 suggests to use QT 7. QT 10 cannot load the movie with subtitles (in Snow Leopard everything was OK). Q& 7 is useless too because it cannot export movies to another format.
Anybody has a solution for this? Thanks for your help!

I do this because Perian don't work with QT10 on Mac OS X Lion:
-Try to open .avi movie with QT 10;
-OS X ask you to open on QT 7;
-Donwload QT 7 and install it. It will be installed on "Utilities";
-Download Perian but don't install it;
-Mount Perian, and click "Show Package Contents"
-Go to "Contents"->"Resources"->"Components"->"CoreAudio" and copy to Desktop "A52Codec.zip" and unzip it;
-Go to"Contents"->"Resources"->"Components" and copy to Desktop "Perian.zip" and unzip it;
-Go to "Contents"->"Resources"->"Components"->"CoreAudio"->Quicktime" and copy to Desktop "AC3MovieImport.zip" and unzip it;
-Then copy all packages with ".component" extention to /Library/Quicktime/;
-Then you can run all movies on QT 7.
Or,
-Install MPlayerX;
Or,

Working with links and exporting to Quicktime

When i create a Quicktime and play it on a Windows PC, it gets confused with internal lnks. I build in some links that refer to another page into the Quicktime file. When i click them on a PC, they start up Explorer instead of going to that page. CAn't seem to figure it out...

Import, edit, and export QuickTime document: wise? how to maintain quality?

Can iMovie HD 6.0.3 be used to import a reasonably-high-quality QuickTime file (Apple Graphics compression), edit it, and export to Quicktime, all resulting in a QuickTime file with the same clarity as the original?
I have a quicktime file that captures a demonstration on my desktop. It was recorded with SnapZ Pro (with movie option) into this format: Apple Graphics, 889 x 500, 256, IMA 4:1, Mono, 22.050 kHz. (Note: I got 889x500 when I constrained SnapZ to a 16x9 format.)
I need to clip out sections, rerecord some of the audio, insert snippets of replacement video (re-recorded). I have Quicktime 7.1.3 Pro, but I had this idea it would be easier to do this editing with IMovie HD 6.0.3.
My problem is that everything I export has noticeably worse quality than the original source. I have tried all sorts of projects (DV, HDV, MPEG-4, ISight). I've tried exports at full quality, lower quality, various expert settings.
For example:
- Create a DV-Widescreen project.
- Import the movie. What I see on the screen is slightly smaller (in both dimensions) than the QuickTime Player shows me, and quite noticeably blurrier.
- Picking Expert export, I use Compression: Graphics, Depth: Color, Quality: Best, key frame rate 24, Dimensions 889x500, Scale: Letterbox.
- The QuickTime file displays as the right size, with a tiny black border for letterboxing, and with crummy quality (text has shadows, making it worse than just blurry.) All this despite being 30MB from a 3.2MB original.
Quite likely, I'm using the wrong tool. I don't have a camcorder - I don't even have a TV - so I don't know any of the jargon. What would be the right tool for this task? Stick to Quicktime Pro?
MacBook Mac OS X (10.4.8)

How would Final Cut Express work for editing quicktime as above?
same answer:
FCE handles dv/NTSC/PAL only ...-
for sure, you can import "any format/res" ...- with loss of quality, if import doesn't fit standards...- and: FCE is the "more mightier" tool, means, you can easiely arrange two/many videos in one picture, arrange them, position them ...-
if you want to stay with your original settings, you have to use QTpro (less convenient) or FCP (less cheap) ...

One Keynote slide + one 7.4 MB mp3 exported to QuickTime = 110.2 MB MOV ???

OK... Title says most. Combining a single Keynote slide with a 7.4 MB MP3 and exporting to QuickTime is giving me a HUGE file of 110.2 MB.
Same slide, same MP3, exported to Flash yields an 8.2 MB SWF.
What's up with that??
I just want one slide to open up in full-screen, and click to play one song with the slide... and a file small enough to email.
Any suggestions?

Ok, the magic key seems to be a Custom frame rate of 0.01. With a frame rate that low, I'm getting file sizes of just larger than the music file. Set Keyframe and Data Rate to Automatic.
The reason why this doesn't happen with Flash is because flash does things the way iPhoto does. Display one static image and leave it there until it needs to change. Keynote COULD do that with QuickTime, but it doesn't
Also, if that H.264 gamma change is causing you problems, I just found you can use PNG. Make the same change to the frame rate (you don't have to alter anything else for PNG) and you get a file just a skosh bigger, but closer to your original colors.

Footage is jumpy after exporting to Quicktime movie

I have final cut pro 7 and im working with to different type of footage. One is from my canon t2i and the other is sony 500v AVCHD. Everything was logged and transfered correctly as prores. Everything plays well in the sequence no jumping between between muiltcam shots.The problem comes into play when i right click on the sequence and export to Quicktime movie. I keep all of the default setting of the sequence it was created from. Again everything plays GREAT in the sequence, so i dont think i have any corrupt files.Its weird its like it jumps from 100% on a clip to 98% and then back again. It doesn't play this way thru the entire sequence. I have the new 27 IMac

Did you transcode to ProRes HQ?
If so, your system and or hard drive may not have enough juice to play it back in Quicktime without skipping.
ProRes LT is what your clips should be transcoded to.
If you have Unlimited RT activated for the sequence with dynamic settings, it may appear to play back correctly, but actually the quality and/or frame rate may be lowered slightly for realtime playback.

Problems Exporting to Quicktime. Would you use Profcast?

Using the new Keynote, which is promising, we recording a seminar that was 2 hours long. We wanted to distribute it via CD. We have tried to export it so many ways to Quicktime. We get the old "Your slideshow cannot be exported as a Quicktime movie. There's not enough disk space, or there was a problem with the file." Of course, disk pace is not a problem. We just found out that this is some sort of bug that the Apple community has been trying to figure out for years and has errupted again with this new Keynote version. We've tried the couple solutions posted elsewhere on the internet, and nicely summarized here: http://www.madebymark.com/madebymark/2006/04/keynote30expo.html
As with the author above, they haven't worked for us. And we don't have a stray "audio icon" that the author describes. Our Keynote presentation is very bare, with new fancy slide transitions or effects.
I'm thinking that Keynote cannot be trusted with audio presentations of over a few minutes. We recorded a nice four minute or so presentation and exported to Quicktime. It worked wonderfully. Has all the nice effects. When we tried a longer recording (10) minutes, all the sound and transitions were out of sync.
Our problem is that we record whole lecture and seminars. If Keynote has a glitch, we are then having to re-record. It's painful and expensive.
We were using Profcast, which allows us to import Keynote presentation and record the lectures. Now Profcast doesn't allow fancy transitions. It also doesn't (or did not) export to Quicktime. It exported to mp4 (I believe) which a Quicktime user could open. But the audio was perfectly timed with the slide pagination. And two other important benefits. The lecturer could easily start and stop the audio. If I'm not mistaken, that's not on option under Keynote. If you start the recording under Keynote, you're on until you finish. If you pause (I don't think there is a pause. I think you must exit) the recording, you end the recording. The final nice thing of Profcast (although I have not used it) is that you can export to GarageBand. At that point you can edit out extraneous material. I'm not sure what to do with it at that point. I don't think GarageBand allows you to export to quicktime. I think you can export to iTunes which is a type of QT. Assuming that one had to edit using GarageBand, that would require person to have iTunes to listen and watch the slide presentation, if I'm not mistaken. The other problem is that when you are using Profcast, as I remember (and I may be wrong on this), you lose all the nice transitions and effects. You still see the same slides with the same quality, but minus the effects.
ProfCast has proven a reliable workhorse, but without the effects. Quicktime is wonderful if you are not recording audio. If you are, nightmares ensue, and there seems little hope for an immediate solution.
Here are my questions. Beyond the few solutions for the Quicktime export problem, does anyone have any solutions? Any suggestions? We have a three hour presentation (it's huge) and are loathe to rerecord it.
Should we just stick with Profcast? Why or why not?
Oscar

Oscar I feel your pain !
We had similar problems from a recent seminar recording.
However I don't think it's length related. We recorded 15 presentations. 7 of which did not have slides. All those were fine with just our placeholder screen (25-ish minutes each)
Of the remaining 8 half exported finem, half crashed with the "disk full etc" error. All 8 presentations had slides imported from Powerpoint PC. Slide numbers ranged from 10 to 30. We could not determine a common denominator between the ones that crashed.
We tried removing transitions, deleting and re-inserting the original slides and a whole raft of other voodoo especially trying to hack the contents of the KN Package file in the hope of stumbling on to a fix ... to no avail.
This was a one-off live conference, no re-record possible. You don't want to hear this but we were forced to extract the audio and manually resynch All the presentations in Flash
You may have a better workflow, but you DO know you can control click the Keynote file, choose "Show Package Contents" and in there you will find all sorts of stuff including the .m4a audio file
This is a serious bug that render KN completely it's recording feature completely unusable.
But what has been most disappointing to me has been the absolute lack of any feedback from the stuff I have filed on this. Bug reports, Feature Enhancements, and the lack of comments from any of the Apple KN staff on this Apple KN board, does not speak well to the type of support for this product.
But here's the sting in the tail:
Having JUST completed the Flash workaround (at a cost of several thousand dollars in contracting) I just installed the KN 4.01 updater released today and all the files that would not export now do so just fine ! Grrrrrrrrrr.........

Export to Quicktime bug with embedded movies

Hi
I'm having an annoying problem when having Quicktime movies inserted in slides, then recording a slideshow and exporting it to Quicktime. I do the following:
1) Create a new slideshow
1) Insert movie into first slide
2) Create another slide
3) Insert copy and paste movie into this slide as well and add some animated object (i.e. a shape with a motion path)
4) Record slideshow so that the animated object appears while the movie still plays
5) Export recorded slideshow to Quicktime
*What happens when viewing the recorded slideshow:* Start of the presentation. The movie on the first slide starts playing immediately without clicking. *1st CLICK*. Second slide shows up. The movie on the second slide starts playing without clicking as well. *2nd CLICK.* The animated object is triggered, the movie and the animation play simultaneously.
*What happens when viewing the exported movie:* The exported movie seems to ignore some of the recorded settings. Slideshow starts, the movie doesn't play. *1st CLICK.* The movie starts playing (when actually it was supposed to advance from slide 1 to slide 2). *2nd CLICK.* The presentation advanced from slide 1 to slide 2.
It seems as if the export does not interpret all the settings the same way the direct presentation does, which is quite annoying as you don't get the same result in the exported movie you see on the screen.
Workaround: Go to the "QuickTime inspector" button in the inspector window, select the movie, check the option "Start movie on click". Then, go to the "Build inspector", hit the "More Options" button. The movie object now appears in the list. Select it and select "Automatically after transition" in the lower "Start build" part of the inspector. This way, the movie will start playing also in the exported movie.
Still there is another problem now.
*What happens now when viewing the exported movie with workaround:* Slideshow starts, the plays. *1st CLICK.* The presentation advanced from slide 1 to slide 2. The movie on the second slide starts playing without clicking as well! YAY! *2nd CLICK.* The animated object is triggered, the animation plays but the movie stops as soon as the animation is triggered.
So, instead of playing animation and movie simultaneously as in the normal recorded slideshow on screen, in the exported movie, the movie stops the moment the animation is triggered.
It seems as if the "Play Slideshow" and "Export to Quicktime" have different timelines, or different parameters the two modes evaluate.
This happened in iWork '08 and also happens in iWork '09. It's quite annoying. For me it's clearly a bug that should be fixed and is worth fixing. Please Apple, fix this bug.
I also noticed a tremendous amount of crashes while using the export to Quicktime function. While I was trying Keynote in iWork '09 I exported several times to Quicktime and had several crashes just by using this function.

Hi all.
I do exactly have the same problem since Keynote 4.0 and was hoping that it's solved in Keynote 5.0.
As soon as I try to export a previously recorded slideshow, (that has a quicktime-movie embeded on one slide) and one or two little textanimations on it. The embeded movie stops playing when the first animation starts in the exported quicktimemovie. When I view my recorded presentation, everything looks fine.
I do also believe, that the Quicktime-Export-Function does not work correctly because of timeline differences or so.
I would really appreciate a fix, specially becaused I upgraded in the hope that this should have been solved since around 10 months now....
Too bad.
P.S. As a workaround I am currently using also screenflow to record a recorded keynotepresentation to finally receive a movie. But that is kind of awkward too....

Can't export to quicktime v10 from FCP 5

I have recently loaded FCP 5 (Not Studio) onto a G5 iMac.
When I try and export to quicktime it only exports the first
18 seconds or so. My FCP 5 worked fine on my iMac G-4 with Quicktime 7.6 but it doesn't export on my G-5 using Quicktime 10.
It will export using quicktime conversion, but then I cannot get my chapter markers.
Any and all help appreciated.
Michael the Hunter

Thanks for the response.
On my G4 I am using 10.04.11 and it works just fine with my FCP 5. The G 5 that I am having trouble with FCP 5 is Snow Leopard. I figured that the Snow Leopard OS was probably the problem along with Quicktime 10. And you have confirmed that.
Looks like I will have to purchase a newer version of FCP for the G 5 and use my FCP 5 on my old G 4. Thank you apple.
Thanks for your input.

Should exporting to quicktime take this long??

using Handbrake, i have converted from VIDEO_TS to .mp4 encoded with H264 (at 640x476 with an avg. bitrate of 1500 k/s).
i wanted to combine two titles in the VIDEO_TS folder into one .mp4. so handbrake converted the two into .mp4 files which i then imported into iMovie on a new Mac Pro.
in iMovie i created a new project with the two files, selected both, and exported using quicktime. i exported under similar settings to the original files, resolution (640x480), same bitrate (1500 k/s), H264, etc.
the length of the exported movie is approx. 30 minutes.
2 of 8 cores are running the export. (it's still in process) but the initial estimate of time was roughly 600-700 minutes. it dropped down a little bit initially, but is certanly well over 500 minutes.
now running all 8 cores, the conversion from VIDEO_TS to .mp4 via Handbrake took about 7-8 minutes at the similar settings as indicated above.
should iMovie really take over 500 minutes? do i have a setting that is suboptimal? should iMovie be able to take advantage of more cores like Handbrake?
thanks

This does sound a bit long. (Would normally expect expect about 75 minutes on my older machine using a default preset.) On the other hand, if all you want to do is merge the two separate files together as a single file, why not use QT Pro ($30) if you already have it or MPEG Streamclip (free) to save the files in a single container and skip re-compression process altogether?

Difference between Export QT and Export Using QT Conversion?

I am exporting video from FCE4 into iDVD, and can't understand the difference between Export QuickTime Movie and Export Using QuickTime Conversion.
The first is much faster, but the video seems to suffer in quality. Am I missing something?
Thanks!

"Export Using QuickTime Conversion" gives you many more options
(and many more ways of making mistakes); and it always recompresses.
Using "Export QuickTime Movie" gives you the option to uncheck
the "Recompress" box, which should produce a better result,
if you're not changing codecs.
