QuickTime Version 7.0.3 dropping frames

Hello there,
A search in the forums yielded a few posts describing my problem but I was unable to find a solution to solve it.
I am playing HD Movies Trailers from Apple's page:
http://www.apple.com/trailers/
When playing the trailer QuickTime drops frames and sometimes the sound and the image pause for a second and "jump" forward at the same time.
I tend to play the medium size trailers from the HD section.
I still have the same problem even if the trailer is only playing back after it was fully loaded in cache memory.
Any ideas guys?

To play the medium size HD trailers (720p) you need at least a 1.8 G5.

Export Quicktime = stalling / frame rate / dropped frames

Firstly this issue isn't news. It appears it has existed since 2002 at least on these forums and Apple has done nothing.
Exporting to Quicktime:
1) Keynote makes up what seem to be consistent random frame rates on export
- Codec doesn't matter. Photo JPG, Intermediate, 8bit 422, H264
- You can set the frame rate in export / custom / settings it doesn't matter
- Having no video on a slide or having video on a slide doesn't change the problem...
- The last two items do have more information to complete their story
- If you do have a video on slide at say 25fps and export (at same rate) the random will stabilise
but it will stabilise to something bizarre, such as 23.69.
- So Keynote can wreck your frame rate it will drop frames, or even add frames while dropping
others. It is deeply sophisticated in how it destroys stuff on export.
Result
- is a stuttering output if embed video on a slide with a wrecked frame rate
- and a random frame rate if you don't have a video embed
2) The video stalls between slides
- Keynote seems to play a trick by making a single frame span multiple frames
- At the start of the first slide this seems to vary. The first frame can be between 7 and 33
frames depending on some strange internal logic only known to Keynote
- Between slides it will hold the last frame of the exiting slide usually for 7 frames and hold
the first frame of the entering slide for usually the same amount.
- No amount of change to settings such as transition delay, adding a transition, self play etc
will effect this stalling from what I can tell.
- You can analyse the reality of the issue by dropping the resulting file into Quicktime 7 and
changing the video window "time code" display to frames by clicking on it and single framing
through the video. I have Quicktime Pro for the record.
Notes:
- I have every update installed and am running 10.6.2
- I have tried it on two machines, one a clean build, server or client
- Playing the presentation direct in Keynote does not present any of the noted issues
- I have spent the better part of two weeks on the issue trying all sorts of combinations
- Video of different frames rates, sizes, codecs. All useless, don't bother.
Outcome:
- Keynote is completely useless unless you just want to play a presentation in it
- Dropped frames, stuttering video, stalling, mangled frame rates, fake frames
Solutions that aren't:
- One suggestion for video embeds is to enter a strange custom frame rate. For example a
24fps original turns into a 23.69 export, if you up the frame rate to 24.3 the resulting export
is 24fps.
This is a truly hit and miss affair and will require a lot of testing to nail it. Unfortunately I
tested the resulting video frame count in Quicktime against the original video and...
The amount of frames is not the same. Part of my assumption is that the stalled pad frames
are being considered by Keynote and it drops some frames to fake the same length, that at
least -seems- to be part of the result, but it doesn't account for all the lost frames.
- I have also tried just having one slide and exporting that. The same things happen regardless
How Al Gore managed to make "inconvenient truth" using Keynote is a complete mystery. Maybe on Tiger with some old version it used to work, yet from the forums it would appear it has never worked. This piece of software is a clear case of "it just doesn't work"
I hope you find this and stop hurting yourself trying to make this. I might hurt on a bit longer yet.

I can't answer in detail (I started with version 6, which I haven't used in years, so don't know what v5 did) but... a general comment
Software that old is very likely going to struggle trying to edit a VOB/MPG file copies from a DVD
If you are digitizing by playing the DVD through a conversion device you should end up with DV AVI which should edit well
Just what kind of files are you trying to edit?

Dropping Frames/ Uninstall Quicktime?

OK, I'm having the dropping frames problem when trying to capture. I turned off the "abort capture" box and got it to capture, but now the clips won't play correctly. I'm running FCP HD on 10.4.9 with QT 7.1.5. Is quicktime likely the problem? If so, how do I downgrade? I can't find an earlier version for download that says it's for 10.4.9. Help!

Can Quicktime on a Macbook Pro play DVCpro HD without dropping frames?

I know this is a cardinal forum sin, but I think I posted this in the wrong place to start.
Hey All,
I'm trying to output a 40min DVC Pro Hd 60, 1280x720 video to a projector for a large group. I'm using Quicktime 7.2 at full screen playing back on the second "monitor", but it seems like the video is dropping frames. The playback is stuttering and kind of strobing. This is a new 2.4ghz Macbook Pro with 2gb of Ram. The video is DVC Pro Hd from start to finish.
Is this to much to ask from a Macbook Pro? Is there another codec with comparable quality that doesn't take overly long to encode that I could use?
Any suggestions would be appreciated,
Steve

Hi
You absolutely can ... as long as you have the DVC Pro HD codecs installed. I have used a lowly G4 Power Book with 2 GIG on many occasions to playback full screen 720p 24/30 fps from a FW400 drive. (60fps and 1080p might be too much..)
I just project the desktop through a projector and it looks awesome. It's the fewest compression cycles you can get assuming you shot in DVCPro HD.
However I too am experiencing choppy playback from QT 7.2 on MacPro's. In fact playback of any format is choppy under QT7.2!
My MacBook Pro however is fine with the same software...
Something bad is going on with QT....

4K quicktime Movie dropped frames

I hope somebody can help i have a 32gb Ram Mac Pro Mid 2010 with NVida 32gb Video 1066 mhz. Blackmagic Decklink Studio 4K Card and connected to San storage via fibre channel.
I have a 4k quicktime movie file.
Every time i run in Premiere Pro CC, I keep getting dropped frames tried the blackmagic express software and frames did not drop
I have put the footage on SSD drive into the machine but still drops frames

Use recompress frames option when exporting. That'll do the trick!

Quicktime dropping frames in OS 10.5 Leopard?

I'm creating uncompressed .avi movies in Matlab and opening them in Quicktime Pro. Under 10.4 this worked well, and I was able to export high quality movies into .mov format. Now, under 10.5, when I look at the .avi file in Quicktime, it has missing frames and duplicate frames. The exported .mov file has the same problems.
I am using default settings in Quicktime.
Anyone else noticed this?
Cheers
Rich

Similarly...
I get jerky quicktime playback of H.264 640x480 x30fps files which were OK in Tiger. Looks like either repeated frames or dropped frames, which happen randomly.
Also, importing files to FCXpressHD3.5 I get very visually distorted playback (like rising ripple bars on vision) These are also present when vision is rendered and played back from the timeline.
I suspect a quickime / Leopard bug is responsible so will see what happens after 10.5.1.

I have a Macbook Air (july 2012) with OS X 10.8.3 installed. I have dvds with .vob files and have Quicktime Version 10.2 (603.12). I can't play the DVDs. Thereare some features of QT that I like, e.g. precise frame selection and save as .png file-help

I have a Macbook Air (july 2012) with OS X 10.8.3 installed. I have dvds with .vob files and have Quicktime Version 10.2 (603.12). I can't play the DVDs. There are some features of QT that I like, e.g. precise frame selection and save as .png file-help. Am I missing some Apple software? I thought QT for Mountain Lion could convert the .vob files - is there some setting that I have missed?
Any suggestions that preserves a simple workflow much appreciated.

What am I doing wrong? Dropped frames on a 1.4MB Quicktime file?

I am new to all this and get more confused by the day.
So, it looks like HD express runs and is supported on Macbook, so, why is just importing a 1.4MB quicktime file plays fine in preview, but drops frames in canvas? Having used PC programs I am not used to these kinds of problems and wonder if I have something set up wrong!
I have external HD and 2 GB DDR.
The demo flash preview on the website makes it look like you can do all sort of things!
I also set up the system correct, at least I think I did! *User Settings, Program Settings, etc.
PS the file is 18 seconds long...
Thanks!

The standard QT file from the net? What's that? Every file on the net seems different. Sorenson, Flash Video, H.264. What does item properties say the clip is exactly? Most of these compressed formats don't play back in vieo editing applications properly. They're delivery formats not intended for production. FCE is DV and HDV only video editing application. Those are the formats it works with.

Dropped Frames/Quicktime Import

I keep getting dropped frame messages during playback of quicktime footage I imported and am re-cutting. Why?

+Is there a way to transfer the files from the MBP to my MacPro without doing another camera to computer baby sitting job? Maybe via iDisk?+
Yes, this is quite easy, but don't do it via iDisk.
Option 1 - copy the clip files from the MBP to one of your firewire drives. Then move the firewire drive to your MacPro and copy the clips to your Capture Scratch folder.
Option 2 - Shut down your MacPro and then start it up in *target disk mode* (hold down the "T" key while it starts up - eventually you will get a FireWire icon on the MacPro's screen - that tells you it's in target disk mode).
Then Connect your MBP to your MacPro via a firewire cable. Copy the clips directly to the Capture Scratch folder on your MacPro. When you're done copying, on your MBP unmount the drive icon that represents your MacPro. Shut down both machines. Disconnect the firewire cable between them.
Here's an article on Ken Stone's website that also describes the process.
Copy speed via FW400 is about 1GB per minute; via FW800 is about 2GB per minute. There is no compression involved - you are merely copying the files from one location to another.
One more thing - after you copy the clips to your MacPro, shut down your MacPro and restart it. Then open one of the clip files in QuickTime (on your MacPro). If you get an error message that says you are not allowed to open the clip because you don't have adequate privileges, you will need to change the ownership of the clips (since you captured them on another Mac under a different username, that user 'owns' the files). If that happens, and you need help with it, let us know, we can tell you how to change the ownership.

Dropping Frames playing Quicktimes

Hi All,
Some help if anyone knows. Heres my setup, Desktop G5 Dual 2.3 with 1 gig of Ram. I'm working with Quicktime media: Motion JPEGA Quicktime generated out of a Discreet Smoke NLE System. Whats happening is I'll start to play a relatively short clip, 30 seconds, and it will give me the dropped frame
warning.
First thing, is 1 GIG of Ram sufficient for these files? Or is this some kind
of preference setting? I did notice that the QT files had audio at 32 Bit
where the sequence settings only allow you to go to 16.
Any responses appreciated
thanks

Non Drop frame capture causing out of sync clip?

Hi, All,
I've been having trouble with sync issues on an hour long tape capture.
The material was captured from a Canon consumer DV cam (z80) using firewire into my powerbook g4. (The material on the dv tape was originally recorded in Video 8mm and transfered to the Canon via firewire from a modern Sony Digital 8 camera.)
The sync on the DV tape looks fine when I play it back through the Canon camera. So I'm guessing that I might be losing sync because the camera is dropping frames that don't want to be dropped. I tried to change the video capture settings to non drop frame (in the device control tab of FCP5's audio video settings preference window,) but as soon as I start the capture from the canon, the settings on my log capture window automatically revert back to drop frame. (I don't know this for a fact, but I do notice that the ":" in the timecode box turns back to ";" every time I start the capture.
Does this sound like it is, in fact, a drop frame problem? And if so, is there any hope of getting a canon consumer camcorder to capture at non drop frame rates?

Well, after trying most of the suggestions here, I did find a reasonably hassle free workaround to capturing the hour and fifteen minute footage of 8 bit 32 kHz video to FCP with minimal sync slippage over the length of the footage.
I finally gave up on capturing the material in FCP and instead hooked the canon z80 up to an old version of Toast Platinum 6 I had on my computer. Toast creates a raw quicktime movie file with the extension .dv. Toast then allows you to edit that quicktime file, add chapters, button pictures, etc. thereby making a new file to replace the raw QT it first created. After some experimentation, I discovered that the original raw QT file Toast creates can simply be dragged intact to the FCP browser window, where it becomes a clip with minimal sync problems. I would caution against trying to use the second improved QT file that Toast creates after you've edited your file, as this second QT movie seems less stable than the raw one it first creates.
A final caveat for Toast users. Make sure you set the preferences so that they don't DELETE the original file it creates. There are settings that will tell Toast to do just that either After a Day, After a Week, When You Close the Program or Never. I'd set that to Never, since it can be highly unpleasant to discover that your program has deleted the very file you were planning to work with.
Hope this is of some help.
Thanks to all who pitched in and offered suggestions. Your help has been invaluable!
I now mark this issue Solved. Or at least as Solved as I plan to get it!

Dropping frames in QT export from CS3

I just got CS3 for my PC and I was all excited about the new
feature that lets you export dynamic/actionscripted/MovieClip
content. I do animation targetted at TV, so everything needs to be
rendered to AVI or Quicktime, so I figured that this new feature
would let me use a dynamic camera symbol as I've always wanted to.
I've run into a problem, though: the export process seems to
drop frames! As far as I can tell, Flash is rendering and recording
the frames of the animation in real time (or perhaps just close to
real time). If the computer has any hiccups because of another
process demanding some processor time then the resulting quicktime
will have frozen bits where the renderer couldn't keep up.
You can see what I'm talking about by looking at the
quicktime and an AVI of the same scene here:
http://www.pinkandaint.com/flasherror/bad.mov
http://www.pinkandaint.com/flasherror/good.avi
To test this theory, I tried witching applications a bunch
during a render. Sure enough, there were long sections in the
resulting quicktime where the renderer missed frames. The quicktime
is the right length and number of frames -- it just repeated the
same frame over and over where it couldn't keep up.
That's not the only problem, though. When I look at the
exported quicktime file in either Quicktime Player or Premiere pro
(version 1.5) it reports a framerate significantly lower than in
the original FLA. In the file I'm looking at right now, the FLA's
framerate is listed as 29.97 but the MOV file reports a rate of
19.29 (which is, incidentally, different than the framerate I got
any other time I exported the same scene). In premiere, when I tell
it to interpret the footage as having 29.97 fps the clip gets
significantly shorter than it should be -- in this case 161 frames
rather than the 208 frames that it is in the FLA.
I'm pretty sure this is the same way that the various
SWF-to-video programs do things. I thought it was an interesting
kludge to use those external programs but I was sure Adobe would be
able to do something more elegant and sure-footed with this new
export feature. Couldn't they have somehow guaranteed that each
frame would get captured? It seems like they could have just
modified the Flash player to play with artificial time, where the
time to render each frame was always reported as 1/framerate.
Oh, and there's one more problem. The Quicktime renderer
seems to do something different about the order of execution of
actionscript or something. In the rendered quicktime movie the
first frame displays my camera symbol even though I explicitly made
it invisible with actionscript on the first frame of its timeline.
When displaying in the Flash player the first frame does _not_
display the camera symbol....
Has anyone else encountered these problems? If so, have you
figured out a workaround? I tried setting the framerate really low
(I was at 29.97, so I set it down to 10) but it still seemed to
miss frames.
-David

I can understand your frustration with this feature as it
tries to capture in real time what's being
compiled in the player - but your last line is a bit unfair:
"...it
> exemplifies the Flash team's disregard for animators in
favor of web developers."
Copy Motion and Copy Motion as AS3 are useful new additions
for animators. I will add however that I
myself have a list of animation oriented features I would
love to see added in flash but for now
have you checked out www.flashants.com and their SWF2Video
tool? It exports an SWF to AVI with
flawless results. Worth looking into if you have the need to
output any kind of flash content to video.

Capturing non-drop-frame as drop-frame??

I have to capture a bunch of amateur tapes shot with various cameras. Ultimate destination is NTSC DV. I have a sense that if I capture the non-drop-frame in a standard NTSC DV setup that I might have some buggy problems. Or at least the batch capture is telling me so.
I've never come across this problem before. What should I do? I'm just trying to build a movie database for a CEO using all the stuff he's collected from various sources - wanting all the captured material to be easily editable in FCP.
Any help would be most appreciated,
Ben

Well, after trying most of the suggestions here, I did find a reasonably hassle free workaround to capturing the hour and fifteen minute footage of 8 bit 32 kHz video to FCP with minimal sync slippage over the length of the footage.

Dropped frames on Xserve RAID upgraded w/750GB drives.

I'm capturing in 10-bit uncompressed standard definition 720x480. I just upgraded one side of my Apple XRAID, (connected directly via fibre channel) with seven, 750GB hard drives from Apple, drives designed for the XRAID, (came with there own sleds.)
Current Xserve RAID firmware version is at version 1.5.1/1.51c
Before the upgraded drives, no issues with dropped frames, (drives 1-7) the other side of the same RAID has no problems, (currently running 250GB drives, drives 8-14.) All sleds are populated with drives of the same capacity, (respective to each side.)
The drives were formated using the Xserve RAID Admin software and mounted using Apples Disk Utilities, Journaling turned off. The final formated capacity of the RAID on drives 1-7 is 4.1TB.
When I capture to the drives on the upgrade side, I get dropped frames. When capturing to the other side, no issues, works great. I checked the settings for performance and they are the same for both sides, as follows:
Use Controller Write Cashe - ON
Allow Host Cashe Flushing - OFF
Use Drive Write Cashe - ON
Use Steady Streaming Mode - OFF
Read Prefetch: 128 stripes (8 MB/disk)
My capture box is an AJA I/o and has never given me dropped frames till now, but only on the side of the RAID that has the new 750GB drives. I also have another RAID that uses 500GB drives on both sides and it work just fine as well, (no dropped frames) using the same performance settings in XRAID utilities.
Any suggestion on why these new Apple drives modules are dropping frame would be very much appreciate. Again 7 new 750GB drives from Apple w/sleds having dropped frame issues.

I'm capturing in 10-bit to avoid loss of quality from analog sources like BetaCam SP as well as line 21 must be part of the captured file, because it contains line 21 for captioning. Eight bit has a banding issue that I can't have in the final product and 10-bit doesn't have this issue.
Source quality is maintained completely when working in 10-bit uncompressed, as well as the captioning data that I need, which is stripped out of the captured video latter. Captioning software can read line 21 of the raster area, of the captured file.
Source video is from BetaCam SP, DVC Pro and DVCam.
The RAID is an Apple Xserve RAID, connected via Fibre channel directly, (no xsan.)
I also create high quality QuickTime Streaming files from these source files, the higher the quality of the source video the the better the streaming files look when created.
I have never had any problem capturing till I installed these new drives from Apple.
The RAID is as stated above, is an Apple Xserve RAID, connect via a fibre channel card in a Mac Pro 3.0GHz tower, (no xsan is used, due to connecting directly to the XRAID.)
