Play back is jumpy and lags, help

I have a total of about 4 hours of video I'll be making, and on my timeline I've nearly hit an hour. I lowered by playback settings to Standard that way is reduced the picture and played smoother. It made it work for a bit longer rather than lagging immediately.
The problem is the video, the video lags while playing and then eventually freezes on a frame but the audio continues. This obviously is annoying, but also making is difficult to edit. Are there setting somewhere I can lower the performance that will assist here? If I'm lagging at an hour its going to be impossible at 4 hours.
If I exported to quicktime and imported it again, would it lower the quality? I'm willing to work around it...maybe exporting a half hour at a time. Any idea? I lost all my data once and I don't want to "test" anything for fear of losing it all.
Thanks

Too many audio clips, or overlapping audio clips, can cause the stuttering problem. Varies from computer to computer and project to project. I know of no lower quality resolution settings other than the Standard that you are using. You can toggle between small screen view and full screen view, and that sometimes can shake it loose temporarily. Also, unchecking the preference to center the playhead on playback can sometimes help. Make sure that your boot drive has at least 20GB of free space. If you can remove some of the overlaps while editing, and then put them back later, that might help. Or don't add all of your audio until you have finished editing the video.
Exporting to Full Quality Quicktime and importing again will not cause any loss of quality (at least that I can see). But it will limit editing if you do that with the whole movie. With longer movies I handle that by editing separate segments in separate iMovie projects, and then bring the segments back in to your control project as Full Quality Quicktime Movies. That limits the number of audio tracks and eliminates overlapping.
You also can export all or portions of your audio track as an .aiff file, using the Expert Settings. That will merge the clips thus limiting the number of audio clips and overlaps.
One other point: You will not be able to fit a four hour project onto a standard 2 hour DVD. You will need to use a dual layer disk or split your movie between two disks. Check your hardware profile to verify that your burner can burn dual layer disks.
Perhaps others will have additional suggestions.

Sony XAVC files from F55 no longer play back at all and cause glitches since update today - 13th Dec

Hi,
Since updating Premiere today any Sony XAVC files I have in my projects no longer play back and cause fairly big glitches. All was completely fine yesterday before I updated. Does anyone have any info on this? Hoping for a fairly quick patch as it's rendered a time sensitive project I'm on unworkable.
Thanks

Thanks Jim, trying this now and hopefully it'll work

CS3: Exported .mov file plays back very slowly and choppy

I'm exporting a 1020x574 stage to Quicktime, H.264 High
quality, no sound. The resulting video, no matter what size I make
it, always plays choppy at parts. It plays fine in Flash and as a
.swf, but the .mov lags badly.
Any ideas what's going on?

Yes, that's the exact same problem I'm having. And I see the
same thing, where areas with more objects tweening and effects and
such have the lag. The thing is, when I play the .swf in the Flash
Player it runs without *any* lag, so it doesn't make sense to me
why lag is picked up when it records it for QT.
I have noticed that if I shrink my entire stage and export at
a smaller size, it runs without lag. That is not an option,
however, I need the larger size.
Well, that's disappointing. Next step is to try and find a
good screen video recorder and manually record the playback.

HT201177 I am trying to create home movies and each time there is no sound when I play back the disc. The sound is there when I play back in imovie and also after I've shared with idvd and played back. Not sure what else to do???

I am trying to create home movies, and do not have sound on the final disc. The sound is there in imovie and after sharing to idvd. This has only happened a couple of times before and I have made a lot of movies. I have just gone through about 8 discs, all with no audio when I play them!!!

You need to ask for support in the iMovie forum.

Recording and Playing back Streaming Audio and Video

Hi Folks...
I posted this in another forum too. I have this sample code from the e-book: "Learning Flash Media Server 3". The purpose of the code is to create a FLV. The code is not running as it should. When I click on the 'record' button, the label is to change to 'recording', that dosen't seem to happen and also when I click on the 'Stop Record' button, I get the following error:
"TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MinRecord/stopRecord()"
I have my suspicion on a certain section of the code as the possible culprit, but I am not sure how to rectify it, I will post the entire code here so you guys can have a look.

             if (ns)
                   recordBtn.label="Recording";

                   ns.attachCamera (cam);
                   ns.publish (textInput.text,"record");
       private function stopRecord (e:Event):void
             recordBtn.label="Record";
             ns.close ();
My deduction is that the 'if' statement in the 'startRecord' function is not resolving to 'true' and hence the label is not changing to 'Recording'. Also I feel that the assingment to the variable 'ns' of type NetStream is not being done and hence in the function 'stopRecord' I get the above mentioned error message when I click on the stop button. How do I rectify these problems?

Hi Amit,
Thanks for the message, I had acutually realised late last evening that changing this:
rtmpNow="rtmp://192.168.0.11/vid2/recordings"
to this:
rtmpNow="rtmp:/vid2"
which is what you have also recomended solves one of the problems which is that of the startRecord function, as my server is running on my own local machine. However when I click on stop record, I am getting the following error:
"Error #2044: Unhandled NetStatusEvent:. level=error, code=NetStream.Publish.BadName
at MinRecord/checkConnect()"
I am trying to figure this one out...if you have any clues, let me know. Thanks.

I keep getting an error 2048 everytime I try to play back my Maya file that I saved as a qt movie. I just recently updated qt and this is when the errors would pop up. Before the update I had no problems. How can I fix this?

I updated quicktime a few days ago and now I keep getting error 2048 whenever i try to play back my Maya file after saving it as a qt movie. I had no issues with this before I did the update, after the update I keep getting the error 2048 message. QT will play my earlier Maya movies and other video, it just won't play back my latest work. Help me please, I need this for school.

The 2048 error message usually suggests the files use MPEG-2 format which is not supported natively on Windows via QuickTime without the additional MPEG-2 Playback Component ($20 from Apple).

Playback on TV is only is only black and white, any idea what setting is causing this. It is played back via a Denon asd-11r.

I have hooked my nano up to a Denon ASD-11R to play back thru my home system. Audio is GREAT, video is only playing back in Black and White. Anyone have ideas what setting is wrong fro video playback?

RAW capture includes color information. The b/w is just a camera setting like white balance that does not change the actual capture of "RAW" image data (which is why we can easily change exposure, WB etc. during post processing edits of RAW captures).
Your solution is to shoot RAW + JPEG capture. The JPEGs will have the camera mods like b/w; or the RAWs can be converted to b/w using Aperture or an image editor like GIMP or Pixelmator.
In the past if pix remained b/w upon import it was because you were seeing the camera JPEGs, not RAW.

Exported movie plays back fast

Hi all, new poster on the apple discusions forum but wondered if anybody out there could help me.
I created my first movie from iMovie last night, the footage is HD from A Sanyo Xacti 1000 camera (had problems getting the footage in the night before but thanks to these boards found a solution)
Anyway cut a quick movie exported to AppleTV, created my m4v file, played back on ATV and the video footage appears to be running fast, almost like it's dropping frames but smooth. Audio was fine too... Anyone got any bright ideas?
Thanks tim

Hi.
Best thing to do is to set Imovie'08's movie format to NTSC, even though the TV standard in the UK is PAL.
But since you work ith non intelaced footaged, this will just change the frame rate iMovie works with to 30fps (29.97 exactly) instead of 25.
Since all Xactis shoot at 29.97 or 59.94, this setting is much better for them.
And it totally eliminated any choppiness effect for me.
Beware though: changing the PAL/NTSC setting of iMovie from PAL to NTSC made very strange results in edited movies (offset edits) when iMovie came out. I do not know if this has been corrected in the latest 7.1.1 version.
But you can always go back to your previous PAL setting and this eliminates all side effects, so there is no real downside trying.
I also have an HD1000 now and have had no problem with 60fps footage- and I now know how to output from iMovie at 60fps
Not sure if this has to do with it, but I do not use iMovie's import feature:
I create a folder for the new event in the ~/Movies/iMovie Events/, copy the .mp4s from the HD1000 to it, and then launch iMovie. IMovie then creates thumbnails and everything.
Hope this helps.
I miss the good old times of miniDV, when everything just worked!

HD play back returns dropped frames on a 10 second playback w/transition

when playing back a clip in the timeline and I have a transition I get a pop up about dropped frames. I am playing back in HD and I have striped my drives for speed, but still the same thing. I have searched the logs and find no matches. I hope you can view the screen capture. I do know that HD plays a factor but tried the options, any ideas

The original footage is 1080i, cannon xh a1, but having it down convert to 720p-60. The 300x2 raid is 500+ free space, I just started the video.
After sleeping on it, I had a thought, I have a BlackMagic intensity pro capture card. I have it playing back on a 27" screen to see the true quality of HD, Its nice, so I thought that maybe on play back its outputting to the canvas and to through the BM card to the TV. I turned off the the video playback in the video properties and I am now able to play a sequence of clips with transitions without any problem.
Thanks for your response, it helped make me think, now off to tackle the BM card

Audition 1.5 has problem playing back MT session if I have a ton of stretched clips

I might be doing something AA is not designed to do, I don't know. Perhaps (I wish) there are a lot easier ways of doing this, but I have a band that recorded, with a song that has 8 vocal tracks, singing as a group. However, they don't all start every word/phrase exactly at the same time, but should - therefore I use the clip stretching abilities in MT to cut the track up each place it's off and stretch it to fit. Normally I don't need to stretch it much at all, but after that tedious job is done the overall project sounds a lot better.
However, now I have this session that has maybe 150 stretched clips (pretty crazy, huh?) and it takes about 30 minutes or more to open. Problem is, now it won't play back decently for some reason; certain tracks sound like a bunch of garble and warble - nothing that can be made out. I do not know if all the stretched clips have anything to do with it. The wave files appear the same as before - example, you can see where a louder portion of audio is but it is nothing synced with what I hear on the speakers.
I should also mention that I had an under-rated computer run AA one time and the same thing happened there so I thought it just got tired and so I restarted AA and it worked fine after that. Here I also restarted AA but the problem is not better - worse if anything.
Some tracks play fine, others don't. Another thing of interest is that I have only stretched the vocal tracks; by far the worse garble is on the instrument tracks; they even play back as quirks and garble in Edit View if I go there.
Anyone have any solution why this happens? Am I over doing AA in some way?
Also, is there a more automated way of matching and syncing vocals? I'm talking about them being .1 - .01 seconds off the beat; is there some way AA will automatically stretch clips to match beats with - say - the beat markers?

I am not surprised at all by your reply!
I would do that, soon as I'm done with stretching/timing adjustment; thing was I was still 10 seconds from the end when it started acting up. But Just as a safe precaution in case it would do something like that I had already backed up a couple of times so thankfully I don't need to do it all over again!
So, you don't think that "set beat markers" (or something like that) can be locked to beats in MT? For example if I run the "Find and Mark" beats in EV and then use those beats to snap to the closest beat in MT, stretching the file as need be in order to get it there.. ? Maybe I'm dreaming out of this world.. Next time I'll have to force my clients to sing until they sing it dead on right!
Thanks for your response!

Mp4 files are playing back green

All of the mp4 files on my computer are suddenly playing back mostly green and pink video. I can hear the audio but the thumbnail and the video are green. If I hover over the thumbnail and press play they begin to play fine. I can then press the space bar while the thumbnail is playing and the file will open up and play normally using quick view. I am running 10.9.5 and also have the most rent version of VLC installed.

>I reset the TV but even it didn't work. It still didn't play the mp4 files
Did you do this correctly?
I mean you have to rest to default settings. In such case every option which has been changed, would be set to the default.
To do that you have to go to:
System Setup -> Reset TV
When the set powers back on, the Quick Setup screen will appear. Press OK to advance the setup and perform an auto tune.
Furthermore the user manual provides a list of Media Player Supported formats (page 93)
There is a list of supported formats for movie files and music:
_Music_ mp4 files are supported.
The files extension should be .m4a
The audio codec should be MPEG-2/4 LC-AAC
The max number of files in the folder: 1000
The _movie_ mp4 files:
The supported file extension: .mp4 or .m4v
The supported video codec: H.264 (MPEG-4 AVC), MPEG-4 part12,14
Supported audio codec: MPEG-1/2 Layer3, MPEG-2/4 LC-AAC and MPEG-4 HE-AAC

Distorted play back sound

Hi and all the best to u all.I have just recorded some live vocal on garageband and went to play it back.It is playing back all distorted and sounds as if its slow any ideas.I am using the 002 Digidesign rack.
Th
Joe

so are you recording first in GB and exporting to ProTools, or are you just using the 002 as an input device for GB? The reason I'm asking is that GB by default records at 44.1K and protools has options of 44, 48, and I believe 96K, and if you recorded in GB at 44.1K, exported it and tried to use that in a 48K protools project it would indeed sound quite distorted and slow...

Inputs won't playthrough while playing back

Recently I had to trash my prefs for Logic Pro 9 which worked perfectly. I could play along with a track and had no issues. After the trashing of the prefs I can no longer hear what I'm playing while I play down the timeline (A/D is a Mackie Onyx 820i). If I record I can hear it play back while I playing, but if I just play back the timeline and play along I can't hear the, in this case electric guitar. I rechecked my Mackie settings and they haven't changed and I reset the prefs in logic:
I have tried it with 'Independant Monitoring Level' both checked and unchecked which made no difference. I know it's probably something I didn't check but for the life of me I can't remember what it was.
Thanks!

Figured it out. Thanks anyway.

I play Farmville on Facebook and since changing to Firefox the "lag" time is unbelievably LONG...and I lose things in the process...tempted to go back to IE. Please help!

I play Farmville on Facebook and on Zynga.com and since changing from IE to Firefox it has SLOWED the process of time between "clicks" so dramatically that my gaming has been affected to the point that I am considering going back to IE...I don't want to do this but cannot understand why I am having this problem with a product that says it is so much better than IE??
== This happened ==
Every time Firefox opened
== When I changed from IE to Firefox

Hello Dara.
You may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
