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:-

How to tell if video is drop frame or non-drop frame in Encore? Need info to use correct SCC file.

Hi,
Thanks in advance. I am using Encore DVD 2.0 to add closed captions to video. I have both a drop frame SCC file and a non-drop frame SCC file. How can I tell which one to use? Can I tell from the way the timecode looks on the timeline? Do I look at the timeline timecode or the source timecode? For example, in a random area of video the timeline says 00;02;50;24 while the source says 00:02:50:20.
Thanks.

Thanks jbowden and Jim for your help. Although I'm still not real clear how Encore notes DF vs NDF (more on that below), I got my problem solved.
Regarding DF vs NDF in Encore DVD...There doesn't seem to be a real consistent method of identifying which is which. For example, Jim suggested that I look in the Project panel for the colons vs semicolons. There, the video file timecode was shown as xx;xx;xx;xx with semicolons, apparently suggesting that it is DF. However, the timeline and audio file listed in the project panel also showed semicolons in the timecode. Then, down on the timeline, the timeline was shown as xx;xx;xx;xx while right next to that it said "Source xx:xx:xx:xx" with colons! So, if I go by the project panel, the video is DF. If I go by what it says down in the timeline, the video is NDF. As it turns out, subtitles and CC only match up if I use the NDF versions of them, not with the DF versions, which indicates that my file was NDF. So, in the end, I'd say that the way the timecode is represented in the project panel didn't mean anything, at least not in this case.

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

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.

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

Apple TV: Movie Lag, Stutter, Misses Frames

I have been backing up some of my home movies that are on dvd so that I can sync them with my new Apple TV using handbrake. I have tried alot of the different settings (apple tv preset, default, etc) but every movie that I watch plays for a bit then either stutters, misses a frame or 6 or moves slowly through a frame sequence. I do not know what to do. Has anyone else had this problem? If so how did you fix it. I read that the apple tv only supports 24fps and that is what I have tried encoding at and no luck. I have tried these same movies on a friends apple tv without a problem. I have tried harddrive syc and wireless play with the same results.

I was assuming it was NTSC rate which is 29.97 fps or thereabouts, but if changed to 29fps might definitely look odd.
The more I think about it, if the videos look great on a friend's AppleTV and presumably different TV, then presumably either the OP's AppleTV is struggling due to an impending hardware fault or perhaps less efficient hard drive, or the friend's TV has fantastic video processing circuitry rendering far smoother frame to frame transitions. The same hardware device will not necessarily produce the same video playback experience on different TV's some having vastly superior processing circuitry.
In fact the OP should consider if he has any playback enhancement features switched on on his TV as such features can occasionally give more problems when siwtched on than without them. I was reading the tech details of newest Panasonic plasmas, and one of the frame intrepolation methods seemed bizarre to say the least in that it almost never reproduced the original frames, giving interpolated versions of the majority.

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....

FCP crashes when capturing uncompressed video/drops frames on playback

I have just started using FCP 6 but had similar problems with 5. FCP seems to work fine with lower data rate captures and playback like DV25. When I try to capture uncompressed 8 or 10 bit SD or HD it will capture for a while then eventually crash. Shorter captures of 20 or so minutes will work ok but then the video will drop frames and stall on playback. It will suggest lowering real time audio tracks, changing the RT settings etc., but it is only a 2 audio track capture with video and RT is already set to dynamic. I have successfully done this before so I know the hardware is capable, I have captured and played back 1.5 hours of continuous 10 bit uncompressed SD without incident. The system hasn't had a lot of other stuff installed on it. It seems like there must be some sort of software conflict.

I am capturing to a Ciprico dual channel U320 array attached to a ATTO UL4D SCSI controller. I don't use the system for these data intensive captures all that often and sometimes I have no problem at all and other times I do. I noticed that the raw movies would play in the quicktime player ok without stalling or dropping frames so the issue seems to be with final cut. The last time I had this problem was with playing back 720p DVCProHD files and it would only play for a few minutes and then give a error message about dropping frames and suggesting lowering the number of audio tracks and changing the RT settings. I am thinking there must be a software conflict. We just installed FCP 6 and this was the first capture I did with it and had the same old problem right off the bat.

Apple TV regularly seems to skip frames

My apple Tv seems to regularly drop frames - the regular frames rate seems to halve when watching content such as tv shows, movies and trailers all downloaded through iTunes - anyone else seeing this?

Cheesenightmare wrote:
Thanks for that reply. I suspect its compression related too, but seeing as the issue doesn't appear on other devices playing the same videos iI am figuring it must be DEcompression related, ie at the Apple TV end.
The problem I mentioned is decompression related specifically on AppleTV.
Most computers these days will be far more powerful than AppleTV so should have no issues decompressing - the issue however was not present on AppleTv until a recent update from what I read.
I must say that even to my overly picky eyes I was very impressed with the HD content I havebought from iTunes so far. I was bracing for far worse (Its no Blu Ray of course, but still better than I was hoping for).
Good to hear.
Even some SD content is extremely well encoded, other stuff is poor - I think the issue is largely one of the SD stuff in the main being targetted to iPod/iPhone use so AppleTV TV SD suffers as the files must be playable by the lowest powered devices.
I wonder if the Apple TV has a sort of "dynamic playback' thing it does, where it drops back to half frame rate if for some reason the processor is not cutting it...or busy doing something else like syncing content.
It may do, but in reality it shouldn't need to.
If it has to do things like this the design is flawed as it should be powerful/stable enough to decode within spec video, especially that from iTunes Store.
A media player device if nothing else has to playback smoothly provided other factors like network issues aren't tripping it up.

Drop Frame being read as Non-Drop Frame

Hey,
I'm working in FCP HD 5.1.4 and our guys are shooting audio at drop frame, and video at drop frame, and yet when we import the media into FCP, the Video is in Drop frame, but the audio appears to be Non-drop so we're getting BAD sync (some clips 30 seconds, others up to a min.). We're using TOD T/C and it's really important that we convert it cuz we'll shoot 8 hr days, and the first few clips arn't that bad but after so many hours, the sync gets worse and worse.
We're using XDCAM Sony PDW-1500 deck for the video transfer and the audio is BWFs from an external Audio receiver, then it's backed up on lacie drives (prob using compressor) then we're syncing in FCP.
Any thoughts?
Fraser

FraserPost, according to Apple in the Late-breaking FCP news PDF on pg.4, Broadcast Wave Audio Files imported will always be interpreted with non-drop frame TC.
Highlight the clip in the bin, choose Modify Menu option and choose Timecode. You can then change it to drop frame in the options panel.
Then your material should synch up.
For future reference but still notable, if you import an aiff, mp3 or another type of audio file without TC, the file will create TC dictated by the Sequence preset setting. This I found out the hard way. One has to shut down FCP and start it up again for the change to take effect on material imported.

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

720P 30 H.264 videos stutter when played back on Windows

720P 30 H.264 videos stutter when played back on Windows
I have an interesting problem that I am hoping someone can help me with.
I have several short videos (2-4 minutes) in 1080i HDV that I have edited in FCP. When output to 720P 30 H.264 in Compressor at either 10 or 6 MB they look just drop dead gorgeous when played back on either of my dual processor Macs.
However when played back on a Windows machine with QuickTime 7, they stutter to the point that playback locks up. This happens on 1.5 GHz to 3.2 GHz P4 class machines with 512 MB to 1 GB of RAM and 64 to 128 MB video cards. On the 3.2 GHz P4, the processor utilization peaks at 100%. The interesting thing is that all of these same Windows machines have no problem playing back 720p 24 trailers at 6 MB.
Thanks all.

First a correction. I am using the latest version of FCP – 5.
Regarding the encoding, I have tried going from native HDV MPEG-2 to H.264 at 720P from 10 to 4 MB at 24, 30 and 29.97. The Mac seems to play everything back very well, but most PCs (the latest IBM T 40 – 43 series laptops) a couple of Dell desk tops (2.6 GHZ with 64 and 128 MB graphic cards) and a 3.2 GHz Shuttle PC with a 128 MB graphic card (that we routinely use to decode four MPEG-4, 4CIF images simultaneously and display on a 42” ED Plasma) choke/stutter to varying degrees with processor utilization hitting 100%.
So, the real issue here is what is the difference between a 720p trailer that I can download from Apple and what I can output using Compressor 2 at a similar data rate – other than the frame rate?
And why does the Compressor output stutter on most PCs?

Drop frame video to non-drop frame clip warning (again)

So my most recent search of why this warning comes up reveals no good answers (unless someone can point me to a thread I overlooked...cuz I can't narrow it down without getting threads about folks who have gotten dropped frames during capture, which isn't the same situation)...
I shoot on an XL2 (drop frame) and capture with a DSR-11. Once in a while I will finish going through log and capture (in the log and capture window), setting ins, outs, etc. but I go to batch capture and it gives me the warning. All my ins/outs have semi-colons, I haven't changed the setting on my camera since I started using it more than 18 months ago, and it doesn't happen all the time. I do have the "abort capture on dropped frames" box unchecked as well (if that matters).
99.99% of the time, I've captured and there's no problems with syncing or anything. Thoughts?
Thanks,
Jonathan

If I recall right someone suggest to have your tape playing while opening Log and Capture, but I might recall wrong
I already have the "Abort on dropped frames" and "report dropped frames" unchecked.
Don't be mistaken: Dropped frames are a totally different issue from non-drop and drop frame timecode.
Drop frame timecode drops (or better: skips) timcodenumbers while counting the videoframes. That is a system to compensate for the 29,97 frames per second in order to calculate the correct length of a clip.
Dropped frames (as in "Abort on dropped frames" and "report dropped frames") is an error. Due to some reason the hardware isn't capable to record/digitize every single videoframe to your harddisk. e.g. Your captured file will have 2000 frames, while your footage on tape had 2003. Three frames were dropped then during capture. And your video will noticeble stutter at these points.
So I'd strongly recommend to do check the "Abort on dropped frames" and "report dropped frames"-options. You don't want stuttering video do you. So if your hardware couldn't handle the videofeed somehow, it would resp. abort capture or warn you that it happened.

7.0.1 "Upgrade" = Dropped Frames. Where is the Apple commercial guy now?

I've wasted 3 hours of my morning trying to correct this issue so far, so any help is appreciated. I "upgraded" to FCS 7.0.1. Now, I can't play more than 5 seconds of video without getting the dropped frames error pop-up. I've tried re-rendering, etc. but to no avail. I have G-speed drives, 2.8 MHz quad-core, and AJA Kona 3 (driver 7.1) card, and it worked fine with the older FCS software. The problem only started after the "upgrade".
I have a problem with Apple working on so many fringe FCS features when they don't have the core functionality under control. Seems a bit idiotic to me as a medical doctor (kind of like trimming a patient's fingernails instead of working on their cardiac arrest). Even the search window isn't showing correctly in this forum (look in upper right corner) on Safari. Amazing...

Went through the entire process with AJA Kona 3 tech support (great people who actually know their product line). It is definitely a problem with the FCP 7.0 software. Apple has a great idea = sell you buggy software and then charge you money to talk to them about it! Fantastic!
When I re-render a segment, it will play without dropped frames the first 2 or 3 times, but then reverts to giving a dropped frame error.
Again, would be great to see Apple fix the core functionality of FCS (like not losing track of a music clip, or making sure the motion tab window refreshes properly when grabbing/moving an opacity edit point) instead of the silly fringe functions.
I'll try the fresh install and then re-render all my high-def work. Always great to lose 2 days (will take at least that long to re-render) after paying $299 for an "upgrade" from Apple. Unhappy New Year.
