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

Pat- coming out of a smoke, I'm imagining they're pretty high rez files... upon what sort of drives are they resident? (Amazing the contortions one goes through to avoid the dangling participle!)

FCP UB iMAC Dropping Frames, playing stops!

It's fine (new here with this program so be easy on me) also a recent swither, after beta testing Vista, I said, that's it. Even though I have thousands invested in software for PC...
Anyway, FCP 5.1
If I use the arrow tool, and move across timeline, the part plays fine with effects.
If I hit space bar I get error, it stops.
Media on second FW drive.
Not sure how to turn off/down compression?
RT set at unlimited, otherwise I wont see the effects.
What is wrong?
Thanks!

Render files are never seen or accessed by the user.
If you want to convert a bit of media, cut it into
your timeline, render it, export it using Export QuickTime Movie...
(keeping it on Current Settings...), import the clip
you created and use that for your source. No more
need to render.
make sense?
Patrick
Ok, I tried this, check it out...exported a 3 second clip, imported back in, no problem, played great!
Added one (as in "1") zoom effect and got a dropped frame rate warning, now, sure, I could turn it off, but surely there must be a way to see this FX in the chain to see how it works or not without an error (2 GB DDR2).
I noticed you can double click the FX than use the time line to see it, but it's a far cry from realtime speed.
Surely there is hope for me yet!
Thanks again

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!

MBPro C2D 2.33GHz/3GB RAM drops frames playing H.264@1920x1080

I've been trying to watch with a MBPro C2D 2.33GHz/3GB RAM a movie (in .mkv container) coded in H.264@1920x1080 (a blueray rip actually), but both Quicktime (I have Perian installed) and VLC would drop frames time to time.
Processor never goes over 100-120%.
Do I have bad codecs installed? Some ideas? I thought my mac would do the job...

H.264 is a complex video CODEC, and there can be many factors in the implementation process which would effect what you're seeing here. It would be nice to see some H.264 analysis tools in order to give us more information about the video stream-- I plan on embarking on some live H.264 video projects for doing live educational video delivery, and access to such tools would be a real plus.
It seems as if the costs in H.264 hardware encoders are dropping rapidly now, with a standalone hardware device (e.g. from Mango in Israel) which does encode/decode audio and video over ethernet coming in at about 5-600 USD. There are even standalone set-top box style decoders for under 200 coming out of China now.

Apple TV 3 video stutter/dropped frames playing on buffer

I'm having an issue with three different AppleTV 3 devices not being able to play back videos via Homesharing on iTunes without dropping frames every few seconds. This is happening with a full (or mostly full) buffer. This has nothing to do with "true-motion" or high-scan-rate TV settings, as I hate those and disable them immediately on every TV I purchase.
I have tried recompressing the videos at considerably lower bitrates, and this does not solve the problem. File sizes are approximately 4GB/hour, and it happens with both 720p and 1080p content. Files are all .m4v, from various content sources. I may be wrong, but it seems that this problem has gotten worse lately, possibly with updates to the devices, but I can't prove that. I know that I was able to watch videos before with no issues, and now just about everything I throw at it will stutter. It also seems as though the dropped frames get worse, the longer I let the video play.
I can't imagine this a network issue, as it happens when the buffer bar is showing plenty of content. I'm using wired gigabit ethernet, but I have also confirmed that it will do the exact same thing if I am using wifi. I have not noticed this to be an issue while watching streamed content, like HBOGo, or Netflix.
I know this seems to be a common issue with these devices, having looked elsewhere on these forums. I'm hoping that Apple will fix the issue, or at least tell us what we can do to mitigate it.

This is a known issue I'm afraid. See the following thread for more info:-

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....

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?

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.

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.

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.

Problem getting HD video to play properly on standard DVD - dropping frames

Maybe someone can tell me the proper workflow I should be using here, but for the life of me can not get my beautiful HD video to play properly on standard DVD's. Footage looks choppy, ie dropping frames.
1.) I've tried editing in iMovie 08', exporting to a 720P Quicktime file (original is 1080p), then loading into iDVD as well as Toast 8. Both play in my standard DVD player like crap (almost like a strobe light is being applied).
2.) I have also loaded the source footage into Toast 8 directly and it also looks choppy.
My source are .mov files loaded from my Panasonic HDC-SD5 into iMovie 08 for editing.
If anyone can tell me what kind of a workflow I need to do in order to get my video onto a standard dvd and play properly, I'd love to hear it.
Thanks
Paul

Hello ipaw,
I think the problem here is a format mixup (I'm no codec pro though)
+1.) I've tried editing in iMovie 08', exporting to a 720P Quicktime file (original is 1080p), then loading into iDVD as well as Toast 8. Both play in my standard DVD player like crap (almost like a strobe light is being applied).+
From what I know AVCHD (the recording format of the HDC-SD5) can be either 1080i or 720p, so my guess is that you shot and edited in 1080i then exported to 720p. The p stands for progressive and, IMHO, that is where the strobe effect comes from.
To go from an interlaced format to progressive (p) you'll need to de-interlace, and that needs some smart software (and skill to find the right settings). On top of that, your source is a highly compressed flavor of MPEG-4, which you're converting to progressive HD.
Why not edit in AVCHD and send the project directly to iDVD?
hope this helps

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!

"Dropped Frames on Playback" - when playing back FCP's Bars+tone

We've been having a problems with one of our edit suites dropping frames when playing back to tape (Edit to tape).
In checking it out, I created a new project and added DCP's PAL Bars and tone to the default sequence. FCP is stopping playback with the "Dropped Frames on Playback" error after 13"-15". I've tried all the usual stuff - trashing FCP prefs, zapping PRAM, repairing preferences etc.
Has anyone any further suggestions??
RT is set to Safe, with dynamic frame rate and video quality.
The Mac is a Dual 2.66GHz Dual Core Xeon, 4Gb RAM, with an AJA kona lhe card, connected to an XServe Raid via fibre. The tape deck is a DigiBeta M2000.
I've read all the posts I could find, and checked Shane's stock answer #12.
Cheers
Steve

Try creating a new user, log into that and test FCP.
In my case, a new user worked, for awhile.
Through a lot of trial and error and a reinstallation that was ineffectual - properly surmised by a very learned friend of mine, Mr. Sheffield - I found a project to be corrupt. So thoroughly corrupt that it would corrupt FCP and any projects opened downstream which is why my new user worked for awhile. Took me some time to figure out the proper order to open things after a system restart. Looks like I'll be doing a rebuild of the project through xml which shouldn't take to long.
In your case, if a new user doesn't help and you go the reinstallation route, uninstall FC Studio with this jewel of a utility. Many thanks to Jon for writing and distributing. http://www.digitalrebellion.com/blog/posts/fcsremover_1.0.6released.html
