Stutter and frame drops during streaming?

After selling my 1st gen for the new Apple TV- I finally got around to streaming a movie from my itunes library. Several times I lost connection. The screen went black for a second than clicked back on. I also experienced poor playdown of the file. It was clearly dropping frames. I am streaming from a 7200 internal disk off a Macpro.
My speed is:
download - 51.28Mb/s
Upload - 5.11Mb/s
I am paying for turbo boost road runner service- so I assume this fast enough.
I used to synced +movies to watch+ to my 1st gen's hard drive and off course they played fine.
I was afraid this streaming nonsense would be an issue- but gave trust to Apple and assumed they had it nailed.
I haven't tried netflix streaming yet- but It has NEVER hiccuped on my PS3- so I'm curious (and scared) to try it on Atv.
Anyone figure out how to improve the performance?

There's a whole thread on the stuttering / dropped frames issue, although I can't comment on whether this is the exact issue you're experiencing. There's lots of info but currently no fix:

Help! Frames Dropped During Live Capture

I am trying to switch over to Adobe Premiere from Final Cut Pro, but am having a serious problem with frames being dropped during capture. When I do have frames dropped, it doesn't even save the video that it was capturing. All that I get is a corrupt file that won't open.
I'm using a Mac Pro with 3.0Ghz Dual Core Xeon Processor, 9GB 667MHz RAM, and a BlackMagic Decklink SDI card, and am trying to capture 720p 59.94fps video over SDI. I am capturing to an interal 1TB 7200RPM dedicated scratch disk that is not used for ANTYHING but live capture. The OS is 10.6.8.
I only have 3 capture options in Premiere using the Blackmagic card: 8-bit, 10-bit or DVCHDPRO. I want to use 8-bit, because DVCHDPRO is 960x720 instead of 1280x720. But, I have tried DVCHDPRO and it did not work either. I can successfully capture video for 5-10 minutes, but then I always get the Warning that frames were dropped and Premiere fails to save the video properly so that it can be opened.
I have used BlackMagic's speed test app and determined that my internal hard drive's data rate is plenty sufficient for both 8-bit and DVCHDPRO.
Final Cut Pro 6 has always captured perfectly fine using this exact setup. It even gives me a lot more capture options for the BlackMagic card - I'm not sure why I'm limited to only those 3 capture settings in Premiere.
I would really appreciate some help to point me in the right direction to get this resolve. Thanks!

Randal,
It might be a bit tough on a fast computer, especially if the BIOS are not set to show POST at boot-up, a common setting nowadays. As Steve says, the exact key will differ by your BIOS brand.
You may not actually see the particular logo screen, that Steve is talking about. I'd do a cold-boot and immediately tap the ESC key. If this does not get you into your BIOS Setup, then repeat, but tap the F1 key. When I say "immediately," I mean immediately upon hitting the Power On button.
With older computers, you had about 5 sec. to get into Setup, but not anymore. On my laptop, I still have trouble hitting the F8 key fast enough to boot Windows into Safe Mode. I miss it, more than I get it. Could also be that I've been away from gaming for too many decades, and my gunfighter reflexes ain't what they used to be, but I'll just blame it on faster computers. I have the same problem with trying to flush my Preferences in Adobe programs, gotta' hit the Shift-Ctrl-Alt key at precisely the right time. [Exact key combo does differ with some Adobe programs]
Also, if you can give us the name of your BIOS, say "Award," we might be able to give the exact key to hit for Setup. If you have the MoBo manual, it will be in there, plus the correct key. You still have to be quick, however.
Good luck,
Hunt

Frames Dropping when Editing back to tape

I just updated my Final Cut Studio to 5.1.4. I am running this program on 2.0 GHz G5 Power Mac. I have fibre from the G5 to the server. I am trying to Edit to tape and this edit stop because it had dropped one or more frames. I am at OS 10.4.9
The error message:
Aborted ETT/PTV – Dropped Frames
Because one or more frames dropped during Edit To Tape or Print To Video, this operation was aborted.
If this occurs frequently, try
- Turning off Unlimited RT
- Lowering your compression data rate.
- Closing open sequences.
- Lowering the preferences for real-time audio tracks.
- Increasing the speed of your system and/or disk drives and/or network connection.
RT Extreme has determined these dropped frames were caused by slow disk. Please try:
- Increasing to speed of your disks
- Decreasing the number of RT lies.
- Limiting your RT bandwidth in User Preferences.
I tried all the fixes stated above and the problem is not fixed.
Please Help
Thanks

Check the settings playback settings in the Timeline window to make sure they are all set to be high quality... sounds like the playback/render quality doesn't match the recording quality so when you ask to edit to tape, it is attempting a total re render.

Rotation lag/frame drop in built-in apps

rotation in the default apps is HORRIBLE. Laggy and frame drops were the norm. Especially the App Store, where the animation took over half a sec to start and very jittery during the animation. third party apps seems fine for some reason. Anyone else experiencing the same problem?

Hi DX
My modem is not rebooting by itself. Are you downloading a lot putting the modem in heavy use? If so that might be the reason why it is rebooting as the cable modem telstra provides have a small NAT table, which causes the modem to reboot when the table is filled up in heavy use.
I think my problem lies either on the copper wire itself or the modem. It has been raining in Melbourne these few days so I have a strong feeling the rain damamged the copper wire

One or more frames were dropped during playback???

I have finally complete my movie.... now when I play it back there are two clips which produce this error message:
"One or more frames were dropped during playback"
It tells me I can:
"Turn off unlimited RT" (which is off)
"lower compression data rate" (no idea what that is)
"Close open sequences" (but Im working with the only one open)
"lowering preference for real-time audio tracks" (??)
"increase speed of system..."
Any suggestions on an easy fix? The clips worked before... I think it was when I added a transition that they stopped working. I took out the transition but nothing changed. I even tried to delete the clips and recreate them from the original source saved on my comp. Thanks in advance!

Sounds like your drive is fast enough? Are you playing back rendered material or unrendered? Are you using Unlimited RT or Safe RT?

Drop Frame and Non Drop Frame

Does QuickTime Pro 7 allow you to select between drop frame and non-drop frame?

I don't understand your question.
QuickTime Player will automatically reduce the implied frame rate to maintain the file playing. You can observe this by viewing any HD movie trailer on a non supported OS.
Frame rate drops so much that the file is nearly not viewable yet the audio portion continues to play back without issue.
The QuickTime author can't set these parameters and QuickTime Pro users can override the issue by selecting to "Play All Frames". This can quickly bring playback to its knees on older systems but it will not drop any frame during playback. It may take two days to view each frame of a 1080 HD movie trailer on a G3 but you should see each one.

"Dropped Frames Detected During Last Capture attempt."

After capturing from DV tape to FCE I get this message;
"Dropped Frames Detected During Last Capture attempt."
What is causing this, and is there anything I can do to fix it?

It is an old DV tape and recorder that I am backing up to the hard drive, and the only other fire wire device is the external drive that I use for a scratch disc. I am using a pass thru fire wire port on the external drive. I successfully ingested 14 other older DV tapes without this message, so it could be a bad tape.
I did sample the video in different areas and it appears OK so far.

Edit to tape confusing drop frame and non drop frame

This is a re-creation of a dead thread I found from June 6, 2006. This is the exact problem this other user was having.
OS 10.4.7
FCP 5.0.4
Dual G5 2.5
4.5 GB RAM
KONALH
Trying to edit to a Sony DVW-A500 (Digibeta) in Drop Frame mode.
Read Below for deets.
Problem: When working with a drop-frame sequence, and editing to tape, the program is edited to the tape with an offset of 3 seconds and 18 frames at the end of one hour.
Reproducible: Yes.
Steps to Reproduce:
1. Create a drop-frame sequence.
2. Edit the sequence in step 1.
3. Perform an edit to tape with the sequence edited in step 2.
What should happen: The sequence should be edited to tape at the time it occurs in the timeline.
What does happen: The sequence is edited to the tape 3 seconds and 18 frames after it should be!
Other observations: 3 seconds and 18 frames is exactly how much time is not in an hour of drop-frame time when compared to non-drop frame time. If you drop two (2) frames in every minute that does not end in zero, the math works out to 2*54=108 dropped frames in an hour. For the sake of simple mathematics, lets say there are 30 frames in a second. So 108/30= 3 with a remainder of 18, or 3 seconds and 18 frames.
It's as if FCP is getting confused about drop and non-drop timecode when the sequence is drop-frame. If anyone can offer any insights, confirmation, or resolutions for what I am seeing, it would be appreciated.
Thanks for reading!

So is the timeline a drop frame timeline, starting at 1:00:00:00?
And then is the DBeta tape prestriped (at least enough to do an assemble edit) to start the program at 01:00:00:00?
In other words, is the FCP timeline timecode matching the Dbeta tape timecode in a 1:1 relationship before you attempt to Edit to Tape?
Thinking further: FCP can't really confuse the two timecodes, it's dependent on the operator to tell it what to do. When it outputs it's not outputing timecode or looking even really looking for timecode. It's looking for your IN point in the Edit to Tape tool.

Linux: flash 10.2 and crystalhd dropping frames @1080p

I'm testing through the adobe stage demo video page the performance of the new plugin using a CrystalHD minipci-e card under linux.
It works somewhat ok @ 720p, as I can see 25fps in the video info window and no dropped frames. CPU usage is 20% in a SL9400 with a 4500MHD.
The problem is that in 1080p I get 4 video fps and lots of dropped frames. Shouldn't this be faster?
On the other hand... why the stage fps stay at 10fps?

Hi, if you have the 10.2 beta, you may want to look at this forum as they have info on Linux.

Exporting different FPS of one clip FCP and compressor dropping frames HELP

Hi all I'm posting this because I have no Idea what I'm doing wrong I'm trying to export my HD file from FCP as a quicktime H264 in 30fps and 24p of the same file. My client needs it in quicktime format but when I export in both FCP using quicktime conversion and compressor the fps playback is 12fps...8fps?. I've exported before not as quicktime with no problem. NTSC 29.97 version and PAL 25p of the same file in quicktime exported with no problem but the HD 1080 at 30fps and 24p wont work. Any advise or suggestions would be great....

Oh sorry, I've digitized my file from HD mini DV cam with FCP. I captured as HDV 30fps from the camera to FCP. I had no problems exporting with Apple HDV codec into different size and frame rates but trying to do the quicktime H264 at 30fps and 24p 1920x1080 is not working frames are dropping I do the same settings in compressor and still doesn't work.

4209 Frames Dropped - 2 minutes of preview

I'm pretty sure I didn't used to have this problem, just playing back video in the program window, but now suddenly, it seems PP6 can't playback HD video in the program window / preview. Don't even bother trying to scrub through the video, that's a disaster.
So, to comply with the guidelines, here is everything I know about the situation. I'm even happy to post the raw footage if you think it would help.
What version of Premiere Pro? 6.02
Have you installed the recent updates? Yes, the updater indicates no updates available
What operating system? Mac OSX v10.8.3
What type of computer? Macbook Pro Retina, 2.6GHz Intel Core i7, 16GB 1600MHz DDR3 Ram
What type of video card? NVIDIA GeForce GT 650M 1024 MB
Hard drive? Solid State Drive
What kind(s) of source footage?
File Path: <SNIP>/AVCHD/BDMV/STREAM/00043.MTS
Type: MPEG Movie
File Size: 1.3 GB
Image Size: 1920 x 1080
Frame Rate: 29.97
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00:08:03:00
Pixel Aspect Ratio: 1.0
Project / Sequence type: I made the sequence by taking the footage and dragging it to new sequence, so the sequence would be the exact type of the source footage. The footage is of panning horizontally of a lake with mountains in the background. It has audio, but I don't play it back.
If you are getting error message(s), what is the full text of the error message(s)? Of the 8 minutes of source video, I took a 2 minute 20 second cut. Put it into the sequence by itself, no effects, no zooming, NO alterations of any kind. Put the marker at the beginning and let it play in the program window at full resolution. I got 4209 frames dropped in those 2.5 minutes
What were you doing when the problem occurred? Nothing else was running, it was after a fresh reboot, only started PP6. Just playing back the video at regular speed with no alterations.
Has this ever worked before? I've edited HD video before, about 3 months ago, I didn't seem to recall this issue.
What other software are you running? Little snitch network monitor, and a CPU monitor
Do you have any third-party effects or codecs installed? No
Tell us about your computer hardware. Be especially certain to tell us about third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU). See above, it's a MacBook Pro, so I can't really add anything to it.
Are you using Mercury Playback Engine GPU Acceleration? Yes. I have turned off the "enable graphics switching" in the power section. I have tried all 3, software, CUDA and OpenCL, usually leaving it on CUDA.
CUDA Drivers? CUDA Driver Version: 5.0.59, no newer update is available
GPU Driver Version? 8.10.44 304.10.65f03
Does the problem only happen with your final output, with previews, or both? Previews, I haven't bothered to try to render it out. I'm still trying to edit the project together.
What else?
Sometimes I get an all RED screen in place of the footage in the program view
I notice that one core is indicated to go FULL red / usage just before and during frame drops, the other 7 cores are green / unused
This happens the most with resolution set to FULL, but also occurs in 1/2 and 1/4 resolution.
Scrubbing through the video is useless
The audio (when I do have it enabled) never drops

Warning:
To those of you who have been struggling with the AVHCD bug and waiting for months to a year to use Adobe Premiere to its full potential... If you don't already know...
Adobe CC introduced another major bug!
I have been following threads about the AVHCD bug for months so I felt an obligation to inform the community members I have suffered alongside.
I am also trying to inform you because Adobe won't. Yet again, they are disastrously failing to inform customers of avoidable problems.
If you upgraded to Premiere CC to fix the AVHCD problem, you could be out of the frying pan and into the fire like I was.
The new bug is described in this thread. http://forums.adobe.com/message/5490602#5490602
Bug Overview:
After saving multicam edits, and reopening a project, multicam edits may loose their link to the location in a clip. The result is that every angle switch restarts at the beginning of a clip. Many of us have lost hours of work like this. The problem may ocurr at any point and ruin work performed prior upon saving and re-opening.
There is a work around described on the thread above to prevent the problem from occurring, but once it does, a project is lost and can only revert to a backup.
I hope this spares some of you the trouble and loss of being struck by the second bug in a row like I was.
I also hope to enlist the help of some of you who would like to join me in demanding that Adobe communicate more openly with their customers.
Again, many people have also been hurt by Adobe's failure to inform customers of a huge problem that they knew about prior to the release of Premiere CC.
Like the AVHCD bug, so many of us could have been spared weeks to months of lost wages and clients if Adobe simply informed Premiere users that there were some issues with the update. As people could have stayed with CS5 for a while to avoid the AVHCD bug, users on this thread could have stayed with CS6 for a while until the Multicam bug was fixed, if they needed that feature.
On that thread, I posted the request I quoted below. Please join us in demanding greater responsibility for communication from Adobe.
please join me in making a feature request:
That Adobe add notifications about important software issues, updates and work-arounds...
to the start pages of applications
and to the Application manager (so that users may make informed decisions about weather or not an update may introduce issues into their workflows prior to installing.)
If they can use those platforms to provide tips and adds, they should also be effective for informing their customers.
Feature requests can be entered at the link below and are prioritized by the number of requests for a certain feature.

Video stutter and artifacting -TM700k video imported using rewrap2m2v

Guys,
I imported a video shot in TM700 to my iMac late 2006 model running snow leopard, using the Automator tool of Alan Somersault -rewrap. While playing the resultant movie .m4v file I am getting a lot of video stutter and artifacting and the movie also quit couple of times while playing.
Any suggestions on resolving this?
Thanks

The movist application actually drops frames during playback to avoid the stutter you've described.
This of course is good for preview. The only other way (within consumer segment) is to get a computer which support hardware accelerated playback, i.e. a later Mac models. However, as hardware acceleration is early, stutter still occurs for some applications but that will improve over time.
If you want to go the free route, use Rewrap2M4V to rewrap the video files to a more friendly format and then use MPEG Streamclip to actually convert the video to a less compressed format.
If you want an "all-in-one" solution, try VoltaicHD for ClipWrap.

Transitions double 1st frame/drop last frame: a solution

I have found that Transitions in iMovie 5 are problematic. The first frame in a Transition doubles and the last frame drops out. This is not noticeable in a slideshow but can be very noticeable in an exported video.
Transitions cannot be edited frame by frame unless one exports video out to a camera and then imports it back into iMovie. The original clips and transitions are now seamless clips. One can delete extra frames and then find and import the missing frames from original sources. HOWEVER, this process is incredibly frustrating and time consuming.
THIS IS WHERE THINGS GET INTERESTING.
To avoid the above, I thought I would add textless Titles over a few key clips and transitions where the glitching is most obvious. I had noticed that Titles longer than the clip they were inserted into, merge together the clip with its transition and following clip.
i.e.,
1. DEselect 'Over black' in the titles window.
2. Select a title format and then a length longer than the 'glitched' transition.
3. Split the clip so that the Title can be inserted.
4. Insert a TEXTLESS Title that spands the clip, transition and into the next clip.
5. Then edit out duplicate frames and insert missing frames from the the now 'single' clip.
STILL just a piecemeal. STILL labour intensive.
THIS IS WHERE IT GETS MORE INTERESTING.
I tested this on a couple of clips and, LO AND BEHOLD, 'Title-merging' a clip with its transition and following clip results in the duplicated first frame of the transition DISAPPEARING and the previously dropped frame of the transition, REAPPEARING. A fix.
One could blanket a video with long textless Titles (i.e., 45 seconds at a time with Rolling Credits) to fix the transition glitches.
I know that this is not a great solution, but it does allow me to export video with the quality I need.
Is there a better solution? (I find it ironic that years later, iMovie 2.1.2 is still, for me, the most successful of all the iMovie applications.)

the duplicated and dropped frames move to the beginning and end of the added short (4 seconds, for example) texless title. Using a longer title (10 seconds, for example) fixed also this.
if I understand your original reply correctly, it is important that the blanket transition ends in the middle of a clip and not a transition.
In my tests I used a blanket title (did you invent this descriptive word?!) that spans some of the previous clip (I split it 1-2 seconds before the transition so I could add the blanket title), the transition and some (1-2 seconds) of the next clip.
If it ends in a transition, the transition plays and then the ORIGINAL clip plays, duplicating the first part of the clip.
I didn't quite follow. I just tried this with a 30 frame transition. Then I added a 1:15 blanket title 1:00 before the transition (so the blanket title ended in the middle of the transition). Result: The first frame of the blanket titles was duplicated and the last frame of the blanket title was dropped. Otherwise it played as expected.
shift select the clips to establish a total length of the video clips and them add a title that ends just inside the last clip.
Yes, I did just that to measure how long a title was needed. In my tests it seemed that it was important that the blanket title wasn't very short (<4 seconds) because then the problem frames were just moved to affect the title. Using a longer blanket title (10 seconds) seemed to fix the problem for both the transition AND the blanket title.
<div class="jive-quote">With a textless title blanketing an entire video, my COMPRESSION TIME to Quicktime is incredibly shortened (1/3 to 1/2 the time).
That's interesting. I've noticed that simple projects (i.e. not much cuts) export faster than real time to Full Quality .dv. But complex projects take MUCH longer to export as .dv. AFAIR this didn't matter in iMovie 1-4. Maybe the blanket title simplifies the relevant parts of the project?
[sigh] I wish we didn't need to be aware of the plethora of obscure gotchas and workarounds like this. I don't expect there to be an iMovie HD 5 update anymore. I guess some bugs will be fixed and some brand new bugs will be introduced in v6.
The same thing happened with iMovie 4 bugs. ...So this time I thought to quickly gather AND report all iMovie 5 bugs to Apple so they could quickly fix them during the first months. ...but it seems that the iLife team just isn't granted enough resources to fix them. Many known old bugs are again just described in the knowledgebase articles.

Lose Network even during streaming!

OK, so I have 2 brand new ATVs (Canadian version if that matters). Linksys WRT160N router. Not only do I have to reset my wireless every morning on the ATV- but during streaming from my Mac's iTunes (which I turned off all power saving except for the screen)- it will still loose connection- and go back to the main screen. This is frustrating as my Wii nor my Samsung BluRay ever do this over wifi. It has to be something ATV related unless someone else has an idea.
Another odd thing- one ATV will see around 10 wireless routers in my neightbourhood and the other will only see mine- they are about 100 feet apart on the same floor. I even did a reset and it didn't solve anything.
I think the ATV needs a fix to keep a persistant connection and also not freak out if it does get a minor disconnect (which is annoying as it will just jump back to the main menu).
***** having a 1.0 device sometimes.
Still love the bugger though- what an awesome device when it is running (minus some obvious updates that will be needed like saving favorites in the various modules)

Same problem, keeps losing connection when in home sharing playing music and reverts to main menu so to get your music back you have to go back through the menu to start music up again.
Yet when not home sharing I can stream music from my iTunes library by selecting Appletv under speakers and it never loses the connection.
So there must be a problem with home sharing that causes the signal to drop out randomly.

Frame-Dropping Issue.

Hello, this is my first post, and I have a Frame-Dropping issue.
I am making a video on FCP and during playback, when I reach the end of the video (there is still audio in the background), it says there are some dropped frames. I tried switching from Safe RT to Unlimited RT and back again... many times. But when I start the playback from a second or two from the end of the video, it works fine. Can someone help me?
Many thanks in advance.

#12 Dropped frames on capture/playback
Shane's Stock Answer #12: Dropped frames on capture/playback
http://docs.info.apple.com/article.html?artnum=58640
1) Do not capture to your main system drive. Since it is busy reading the operating system and application files, it will intermittently drop frames during capture. Capture to a separate internal drive, or external hard drive (firewire and eSATA for example).
2) Deactivate any anti-virus/filesaver software, including Norton and Virex. For some reason these programs think that the large files created when you capture media are in fact caused by some sort of virus, and they try to prevent this.
3) Check the format of the drive you are capturing to. It should be Mac OS Extended, journaling off. If it isn't, copy your files from it and re-initialize it. If it is any other format, you will encounter problems. If not at first, then eventually.
4) Trash the FCP preference files. Use FCP Rescue available here:
http://www.fcprescue.com
5) Make sure that the hard drives you are capturing to are fast enough to handle the footage being captured to it. A regular firewire 400 drive cannot capture uncompressed HD, or even uncompressed standard definition. A RAID array of drives might be in order for these formats.
