HD 1280 x 720 , Skips Frames with Quicktime 7.*

Quicktime skips frames when I'm trying to play a video I created with my Digital camera.(Kodak Z1275) Its not the camera because it plays flawlessly on screen. I upload the file to the computer and Quicktime skips a few seconds throughout the entire file.When I uploaded the HD 1280 x 720 file to Youtube it plays flawlessly.
So the conclusion is its not my computer since the file plays perfect with Youtubes encoder.(I even brought the file to the store I purchased the camera from, the same problem) The Problem is with Quick time player!
Also when I select 1/2 speed playback speed in the Quick time player it is very smooth!Conclusion Player encoder does not like 1280 mode?
I have the latest version and even went to the trouble of purchasing Quick time Pro 7 (that I regret)
Any help from the apple gang?

The only conclusion is Quicktime is not able to process the larger 1280 x 720 format. Only the MAC boys can help! You have to get enough people complaining or find another player encoder that will work with the .mov file.
Kodak, the makers of the camera blame it on Quicktime's obsolete program. Not enough users to make it worth changing or maybe its in the works now.
Seems like Kodak got ahead of Quicktime's ****** player

Editing Panasonic GH1 1280 x 720 60 frame video

I got an old Macbook with previous ver of iMovie which does not support editing AVCHD. I know that iMovie 09 is able to handle AVCHD and support video from Panasonic GH1, so I am planning to a get a new mac with new OS and iMovie 09. Would anyone please share your experience in using iMovie 09 with GH1? I shot the footage in 1280 x 720 60 frames per second in AVCHD format. I understand that iMovie will convert it to Apple properitary video format for editing, my questions are:
1. is the response time acceptable? I believe it is quite hardware demanding for 720p video editing. What is the time rquired for say, a C2D iMac 2.xxGHz 4GB Ram for cutting or addition of transition effect? Do you have to wait for say 30 sec to add a 4 sec transition effect between two footages?
2. what is the output format of the edited video, can it be re-coded to AVCHD so that I may burn it on a DL DVD for paying on a PS3 or blu-ray player?

I got the camera and used in my trip to London last month. Very unlucky that there is no Apple Store where I live in HK, there is only reseller. I will try to test it with my friend new Macbook Pro 13".
If iMovie only import the video at 30 frames, it would not be a solution for GH1 users as the camera shoot at 60 frames which produce very smooth video which I watch the un-edited video on a PS3.
I was quite frustrated with the proper software for editing the AVCHD video. I thought many camera/video camera users shooting so-called hd video would face the same problem.

Quicktime movie export from Flash CS3 is skipping frame.

When I try to export Quicktime movie from Flash CS3, the
resulting mov file is skipping frames. i.e.: The movie is showing
frame number 1, 2, 3, 4, 5, 6, 7, 7, 7, 10, 11, 12, 12, 12, 15
etc...
As you can see the frame number 7 is repeated 3 times and
frame 8 and 9 are nowhere to be found.
The last configuration I used is 960x540, Sorenson video 3
medium quality, 25 fps, keyframe every 25 frames. 6400 kbits/s.
I tried various configurations,with different codecs and even
with keyframe all frames and I always get simillar problems.
Anyone have an idea what is going on, and how to fix this?
Thank you,
Olivier.

The QT exporter in Flash is honestly my least favorite
feature - not the feature itself but how it
works (or how it doesn't work in some cases). For me it is
almost unusable unless you have a very
short timeline, small stage, lower frame rate - like AS
generated effects or something - otherwise,
for true frame accuracy to video output - it is not reliable
enough and not fast enough for any real
world production environment.
So typically for me - I love SWF2Video (www.flashants.com) as
it takes any SWF and makes it into an
AVI that is frame accurate no matter what the frame rate is -
quite incredible - enough so that I
always felt it should have been bundled with Flash (as well
as Wacom tablets).
Harmony is an incredible product - as is SOLO and TBS (Toon
Boom mStudio) - each of those programs
are dedicated animation programs designed for output to video
- Flash has a lot of hats to fill and
it was never really designed for animation to video even
though many of us have found it suitable
for all intents and purposes as an animation program for full
production.
But all in all - the quicktime exporter doesn't really
deliver how we would expect it too I am sorry
to say - I only hope it works as well as it does on the Mac
(Mac users could always choose to export
to Quicktime Video but not PC users).
For now if I am exporting to video I keep it all on the
timeline or nested in Graphic symbols or use
the SWF2Video tool.
hope this helps.

Quicktime 7 plays movie but skips frames

Using Tiger and QT 7.1. The movie displays a frame then seems to jump forward. Seems to play 1 frame out of 30. These are fairly large movie files. Could Quicktime need more memory? If so I don't know how to access that.
Thanks.
Bill

I just noticed what hardware Bill Graham1 lists as his Mac--a Power Mac 7300 running Tiger. He has to be using something like XPostFacto to get it to run on this older Mac. In any case, even if this 7300 has a processor board upgrade, it's not designed to handle Quicktime 7 video at a decent speed. I'd be interested to hear Bill's experience with Quicktime 6.5.2, under OS 10.3.x on his 7300--did it play movies at a normal speed? If so, then that would confirm he's seeing the Quicktime 7 bug, which is actually real--check some of the other posts in the Quicktime section from people with G4 Macs that are more than fast enough to play movie files using Quicktime 7, but who are seeing this problem, where other people with the same Mac model aren't, which indicates it's some sort of bug. My Mac, a G4 AGP at 500 mhz, played MPEG-1 movie files just fine, under OS 10.3.x, using Quicktime 6.5.2, but when I installed OS 10.4, which requires Quicktime 7, the same movie files now play for a few seconds, then stop; if I hit the Quicktime Player window's pause button, then press it again, the video starts playing at a normal speed, but only after skipping some frames, and then plays again for only a few seconds. If I keep doing this, the whole video plays, but that's not how it's supposed to work. The same thing happens when you run Quicktime Player 6.5.2 under OS 10.4.x--you can't run the Quicktime 6.5.2 installer under OS 10.4.x, but you can run its Quicktime Player application if you copy it from a Mac that has 6.5.2 installed--but it doesn't help, indicating the problem is something in the Quicktime 7 extensions, or a problem with some OS file(s) that affect Quicktime playback, at least with MPEG-1 files--I haven't tried any MPEG-2 files.
If you play these same MPEG-1 files using VLC Media Player instead of Quicktime Player, they play with no pauses, on these same "slow" Macs. I don't think VLC relies on Quicktime software. This further implicates Quicktime 7 as the cause of the problem.

Flash to quicktime skipping frames

I'm exporting a complex flash movie to quicktime and it is skipping frames on export. The resolution is 1400 X 1020 and the frame rate is 30 fps. How can I get flash to render each frame?

oops - sorry for the double post!

Dropping Frames with Motion JPEGA Quicktime Files ...720X486

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

I'm having a problem with QuickTime in safari on the iPod touch

Whenever I try to watch a video in safari the QuickTime logo comes up and it loads but only the audio plays and the QuickTime logo just stays on screen. I've erased all history and cookies and cache and also tried powering the iPod on and off and that didn't help ether

My guess is the format of the video is not compatible with the iPod. The iPod does not have Quicktime. The 4G iPod supports these video formats:
H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

Ingested videos not playing in stereo with Quicktime or after exporting with compressor

Why does it seem like every time I try to do something just mildly complex I'm stymied by some bug or problem with the software?
Here's the deal:
0) I have footage was shot with a stereo camcorder, a JVC GR-DV3000 (circa 2003), with built-in stereo mics.
1) I ingest the footage from the Mini DV tape and save it to a camera archive using Final Cut Pro X (latest version).
2) I use Final Cut Pro to pull the events out of archive.
3) When the events are played from within Final Cut Pro X, I hear strereo and audio meters indicate the audio is in stereo (left and right channels have different volume levels).
4) When the events are played with the open source software, VLC, I hear stereo, too.
5) When I export the files for playing on an Apple device using Final Cut Pro, the audio is in stereo as you would expect.
BUT:
5) When I play the event clips with QuickTime from my hard drive after step 2 above, I get no audio from the right channel. Weird, right?
But most annoying of all:
6) When I use Compressor 4 (instead of Final Cut) to output the event clips to "SD for Apple Devices" using the default audio settings, I get no audio from the right channel, either.
7) I've got hundreds, if not thousands, of clips. I'm not about to save each clip manually with FCPX. I need to batch convert these files with Compressor.
8) I've tried various combinations of the audio import settings ("Analyze and fix audio problems," "Separate mono and group stereo audio," and "Remove silent channels." These options have not solved the issue for me. The clips still play in mono in QuickTime.
When I look at the properties of the file in QuickTime, here's what it shows:
DV/DVCPRO - NTSC, 720 x 480 (640 x 480)
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Left
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Unused
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Unused
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Unused
Why it's telling me the other 3 channels are unused, I have no idea. As I mentioned, the footage was shot in stereo and even Final Cut plays it in stereo.
Here's what VLC says about the very same file:
Stream 0:
Type: Audio
Codec:PCM S16 LE (sowt)
Channels: Mono
Sample Rate: 32000 Hz
Bits per sample: 16
Stream 1:
Type: Audio
Codec:PCM S16 LE (sowt)
Channels: 1
Sample Rate: 32000 Hz
Bitrate: 512 kb/s
Stream 2:
Type: Audio
Codec:PCM S16 LE (sowt)
Channels: 1
Sample Rate: 32000 Hz
Bitrate: 512 kb/s
Stream 3:
Type: Audio
Codec:PCM S16 LE (sowt)
Channels: 1
Sample Rate: 32000 Hz
Bitrate: 512 kb/s
Stream 4:
Type: Video
Codec: (DV Video (dvc)
Resolution: 720 x 480
Frame Rate: 29.970030
Decoded Format: Planar 4:1:1 YUV
If anyone can point in the right direction, I'd much appreciate it.

I ended up just using iMovie to capture video from the camera. The clips now play in stereo in QuickTime perfectly.
It's interesting to note that iMovie saves the clips as .dv file types, not .mov file types like FCPX does.
And it turns out the iMovie capture is *much* smoother. It actually "just works." Ingesting tapes with FCPX, I had to cross my fingers, spin on my head and pray three times to a statue of Steve Jobs before it would work (and even then it would do weird stuff).
The only downside of using iMovie is that it doesn't have the camera archive feature.
I really don't understand why, with $120 billion in the bank, Apple seems to be churning out software as an afterthought. No, software is not where they make their money, but they are ruining their reputation. Ah, well, first world problems.

IPhone movies skip frames in iPhoto

iPhone movies skip frames when imported into iPhoto

When you upgraded to Snow Leopard did you select the option to install the Quicktime 7 Player? If not the start a reinstall, select the Custom install option and install just the Quicktime 7 Player. That will let you play the movies from iPhoto (although it opens and plays outside iPhoto with Quicktime Player.

Editing 2 file types in 1 Sequence (1080i60 & 1280 x 720 Flip)

I began a Sequence that is 1440 x 1080, Upper Field, 29.97, Compressor HDV 1080i60, Audio 48 KHz, 16-bit and that is working fine. But, I then added new footage from a Flip camera (1280 x 720, Square Pixel Aspect Ratio, No field dominance, Editing Timebase 30, Compressor: H.264, and same audio settings as original sequence.) This footage plays fine in the viewer but as soon as I place it into the Timeline the audio and video are wildly out of synch. I did set my Prefs to ask when conforming, but it does not ask. I try to manually do so, and it renders, but does not seem to actually change the file format. I adjust the percentage in the Canvas (because sometimes this causes funky playback), and that seems to work once or twice, but not consistently. I tried exporting the Flip Footage with the same exact settings as the Sequence and then re-importing and it's the same problem. I tried a new sequence with the new Flip Footage and that too is inconsistent. I feel as though I have tried everything I know to do-- but can't get a handle on what exactly is wrong, nor how to fix it. Thanks in advance for any sage advice!

I got the camera and used in my trip to London last month. Very unlucky that there is no Apple Store where I live in HK, there is only reseller. I will try to test it with my friend new Macbook Pro 13".
If iMovie only import the video at 30 frames, it would not be a solution for GH1 users as the camera shoot at 60 frames which produce very smooth video which I watch the un-edited video on a PS3.

Apple TV preset : Compressing DVCPRO HD footage : Results in skipped frames

I've been super confused about the recent issue. I've got a 7 minute sequence in FCP which I'm sending to compressor. I'm compressing for my Apple TV. I use the preset, in the Apple Devices folder.
The movie compresses fine, in about 10 minutes. Final size is about 250MB, 960x540.
I have 4 spots where the movie will actually skip a frame. It's VERY detectable because these are Motion sequences with some very flowing camera movements. A skipped frame is like getting punched in the eye. This is seen on my MacPro and my Apple TV.
I have recreated this issue about 10 times, always with the same spots on the movie. I can't get rid of them. I've checked the original files, the original sequence, and there's no skipped frames. I've exported to H.264, no problem there. I've exported to iPod, and the same thing happens.
What's the commonality?... the m4v compressor.
Now, I've imported the full DVC PRO HD film, as exported from FCP, and put it in iTunes. Then I choose "convert for Apple TV." Final size is 190MB, about 60 MB smaller than the compressor version. Reason?.... Who knows what the settings are for iTunes to AppleTV?
This version plays smoothly, with no jumps or skipped frames, on my MacPro, and on my AppleTV.
What's is up? I am trying to figure out if my DVCPRO HD sequence is trying to shove too much info into an m4v sequence using the preset, and the result is that compressor just throws a frame away here and there.
This totally *****.

To be perfectly blunt, you are best off going 960x540 since you're shooting 60i.
If you were shooting a 24p format it would make sense try to 1280x720 (since all you'd have to do is resize) but since you're attempting to retime as well (and only gaining frame judder, the choppiness that you speak of) it's not worth the time and effort. Sure you can export your FCP timeline out to a reference QT movie and drop that into Compressor - creating a PhotoJPEG movie at 1280x720 and 23.98 (making sure Frame Controls are all cranked up to Better, and output set to Progressive) but it'll take forever.
As for export to TV, I personally always use QuickTime Pro's Export to MPEG-4 feature, since I can make an h.264 encoded .mp4 file that uses Multi-Pass (being careful to adjust settings to within the TV's specs). All the AppleTV presets - even in Compressor 3 - are subpar and single-pass.
Of course, if you'd rather have a .mov file, just use Compressor to do that.

Why is 960 x 720 really 1280 x 720???

Really confused at this second. I shot on the HVX200, 720P... which frame size is 960 x 720... but then why when you output or look at the actual file it states that its size is 1280 x 720?
Anyone?

If you'd read the Terms of use, you would realize this is a site for supporting/problem solving technical issues with FCP. It is not intended to offer instruction in video 101.
Lyndia.com and ken stone's site offer a number of tutorials and other support mechanisms that you may find enlightening.
Good luck.

fwiw - anamorphic originally refered to lenses that compressed the image horizontally but not vertically so that there was a non-linear relationship between the image in real life and what was recorded on film. The film had a 4:3 aspect ratio but, by using a lens that compressed the horizontal when recording and using the reciprocal lens when projecting, one could record and play back much wider aspect ratios.
What is relevant about that bit of history is that anamorphic has come to mean the recording of pixels that are wider than they are tall, with the result the 960 horizontal resolution pixels take up a 1280 space. Of course, you know video has always used a non-square pixel. In terms of Standard definition, it has been narrower than tall, eg DV SD is 720x480, which has a square pixel equivalent of 640x480 (a 4:3 ratio). Anamorphic 16:9 means the pixels are wider than tall. The specific width varies with the codec. It is a way to save bandwidth and to get more out of a limited format.

1280 x 720 | 30 fps versus 320 x 240 | 30 fps

Why does the info for some of my video say 1280 x 720 | 30 fps and others say 320 x 240 | 30 fps and they were taken with the same HD camera on the same day. Did I accidently change a setting on the camera?

Seems so.. For safety reasons, try to open them in Quicktime Player and show the Info window..
Or, you could also click it in Finder in coloumn view and the preview will tell dimensions too..

Jog Shuttle - Rewind Skips frames

I am trying to figure out how to encode in Quicktime a mpeg4 or h.264 movie with a smooth rewind (shuttle). I am coaching a sport and trying to teach with the video. After encoding, the video plays fine and actually the fast forwards goes smoothly. But the rewind skips frames . I capture from my camera in dv (avi file) with 720x480 and 29.97 f/s with about 3m bit rate. I don't care the size after I encode. When I play the avi file in QT it rewinds fine and QT goes through each frame, but when I encode to mpeg4 or h.264, the video skips on rewind. Any help would be awesome!!!

Sorry Kyn Drake, here's the def. of what a b-frame and bidirectional frame are....
Bidirectional Frames:
Using bidirectional prediction increases the compression efficiency and the quality of your video. A bidirectional frame is a frame created by the compressor and inserted between intraframes and/or interframes. The compressor analyzes the frames before and after the bidirectional frame and then creates and inserts a frame based on the average quality of both.
Has nothing to do with playing a video backwards...
B-Frames:
The advantages to using the B-Frames are to achieve higher quality of the video and the ability to have playback scalability. By default, the B-Frame setting is set to off. The options in the drop-down menu are: off, Auto, 1, and 2.

AIC 1280 X 720 to MPEG-2 Looks like crud using imovie | buy compressor?

Repost from "compressor" group.
http://discussions.apple.com/thread.jspa?threadID=2075563&tstart=0
I am a complete newbie to the video editing and compression world. Please forgive me and thank you in advance for your advice.
Here is the low down. I am using Final Cut express. I edited a 4 hours training video with screenshots and some screen capture. This is training video on how to use some technical database software so the screen captures are movies of my computer screen captured with iShowU. My FCE sequence and screen capture video was recorded using Apple Intermediate Codec 1280 x 720. When I try to use imovie to burn the footage to a DVD everything looks very grainy. It looks like crud. When I export to Quicktime in the AIC format looks great.
Since I am a newbie, I know I probably should have recorded my screen captures in another codec and not 1280 x 720. Hindsight is 20/20.
I have noticed when I export from Final Cut Express to H.264 it even starts too look grainy. I really need to actually get in on several DVDs in the MPEG-2 format.
So my questions for you is:
Do you think this is something that Compressor will handle? Can I take 1280X720 AIC and use compressor to encode to MPEG-2 and not get grainy resolution? I think compressor can crop instead of scale which I think is what iMovie is doing when it encodes from AIC to MPEG-2. I was using the iMove professional encoding and even tested it with a 30 second clip and it looks like crud. I know compressor offers more fined grained control. I think the grainy MPEG-2 results are from iMovie trying to scale from 1280x720 to 720x480. (I think)
Or should I go back and create a new sequence and re-record all my screen captures in a better resolution that is DVD/MPEG-2 compatible.
I am not sure if this is a screw up in my choice of capture resolution or if it is a limitation of imovie. I am just hesitant to drop the coin on FCP if this is not going to work. Thanks again

No, I don't think Compressor can handle it. MPEG-2 is too heavily compressed to handle compressing screen captures. It's always going to look awful. The limitation is in the DVD format and MPEG-2. Most training DVDs for software are not made using MPEG-2, but using computer formats with a runtime player for playback on a computer monitor not a TV set.
