Ichat Frame Rate issues, low FPS

Hi,
My Father has a G5 1.8 iMac (20") w/ iSight and Tiger, connected to the internet via a cable modem. His upload and download speed are great. When he connects to me in iChat (or anyone else) he initially hooks up at about 15 fps+, but within 5-7 sec, drops to 1 fps, and stays there. He has been unable to get greater than 1 fps sending his video, which results in quite choppy video for anyone on the receiving end.
Any ideas on how he can get his frame rate to increase? I've run out of ideas.
Thanks,
Tyler

Hi Tyler
What apps are running in the background, eg:Virex for one can take the frame rate down and is not compatible with 10.4 so uninstall it.
Also some widget's can cause frame rate loss so turn them all off to check.

Video frame rate issues

When I watch flash videos (mostly in hd and from youtube or gametrailers) in full screen, the frame rate becomes noticably slower. I have tried the 10.1 beta3 and this fixes the frame rate issue, but several times per video the image garbles. Everything runs fine outside of fullscreen. Otherwise I'm using Vista/Win7 64 bit with a 2.6 ghz Core 2 Duo, a radeon 4850 (latest drivers), and 2+ gigs of free memory. When running 10.1 without hardware acceleration or earlier versions with default settings my cpu usage never goes above 20% on each core. Does anyone know how to fix the image garblng or low framerates while in full screen?
Thank you in advance!

This is the tearing that I get with acceleration enabled

Frame rate issues when displaying video on 50" Plasma

I've been using my Mac Mini (Late 2009) as a media centre since I bought it in Dec 2009. Until recently it's been great working with everything I throw at it.
Over the last two weeks though I've noticed issues with lower frame rates and jerky video performance. When I try to watch a film full-screen on my 50" tv I get a much reduced frame rate to the point that I'm using it less and less as a media centre. When I run them windowed the frame rate issue is still present but less apparent than when I run it full screen.
During full-screen playback my processors are at 85%-90% capacity.
System:
Mac Mini 2009
2.53 Mhz

I've been trying it with the digital version of Tron Legacy (m4v format, 1.84GB, 854 x 480) and more simple .avi files ripped from my dvd collection and get the same result.
Action Taken
I've reinstalled the 10.6.7 combo
Run ONYX to update to preferences etc
Ran TechTools to check any memory issues
Looking for any tips as this is really confusing me. My next step is to wipe the entire system and start again but I only did this a couple of months ago so I'm not keen to try again.

yeah I'm kinda limited, working with video for the web and I'm making revisions as to what has been already posted. The H264s are the originals per say as we are using a screen capturing program to obtain the video, I could re export the originals at a truer format, but with the resources I'm given, its not truly the option I can afford to take. I've found a workaround through using imovie of all things, but I rather be in FCP. I've done some editing with h264s before and this is the first time I've seen this happen, it kind of reminds me of when I had an editor a few years back digitize video that was drop frame as non-drop.

Frame Rate Issue Exporting .mp4 using h.264 compression

I really like the h.264 codec, but I have to use Quicktime Conversion, instead of QT Movie, when I export. I get a 'Codec Error' when I try to export as a QT Movie. That is the first problem, but I work around it.
The frame rate issue comes up when I try to export at larger screen sizes like 640x480. I have no problems at 320x240, but when I move up to the larger screen sizes the resultant QT mp4 plays back at 1/2 the specified frame rate, no matter what frame rate I try. It is really bizarre.
I tried lowering the key frame number to reduce the processor load on playback, but this had no effect. This was a tip I picked up here.
I tried lowering the bit rate, too. The only thing that 'fixes' it is to go back to the lower screen size.
The problem is reproducible when the file is played on other (faster) computers.
Any ideas?
thx

Mike,
Try posting this in the Quicktime forum. Pehaps those smart folks can shed some light on your issue.
Good luck.

Want frame rate of 30 fps

I create animations at 30 fps. When I put them in FCE HD the last frame is left out or black. I need to set the frame rate to 30 fps instead of the default 29.97 or maybe use non-drop fame setting. I am not sure which will work. How do I reset the frame rate to 30 or non-drop? Using Tiger on a G5.

Gary,
Drop or non-drop frame affects timecode only not the actual framerate or number of frames.
I've had a quick play at this and can't re-create the problem. I've tried with a 30fps interlaced and a 30fps progressive clip.
What are you dong with your animations after working in FCE? If you are outputting to video or DVD you are going to need to work with PAL or NTSC framerates anyway.
If you are just using FCE to edit your animations and then saving to Quicktime, etc perhaps you could try the 720p30 HDV setting. Although I don't know if the 30 really means 30fps or whether it's the same deal as NTSC (i.e. 29.97)
Or prep your material for FCE. Use Quicktime Pro to output your animations to 29.97fps. If they are progressive maybe making them interlaced might help.
Since you can't do a lot to the set-ups in FCE you're best altering your animations to suit.

Premiere Pro CS6 for Broadcast ProRes HQ Frame rate issues

I switched from Avid to work on a quick project with DSLR footage shot on the 5D Mark III at 29.97 psf which is not to be confused with 29.97i, a standard frame rate necessary for broadcast. So the commercial spot was cut together, I punched in the proper settings (the very same settings that work with Avid 6.0+ and Final Cut Pro 7), and hit export. When exporting either a Quicktime Animation or Pro Res file from Premiere Pro CS6, premiere creates a file with a faulty framerate, it comes out as 28.4 instead of 29.97. I thought I was going crazy, but no, there are tons of documented experiences with 23.94 being 20-something, and on an on. It seems as if Adobe did not do a good enough job with integrating the Pro Res codec into their software. The only way I could get around it was to export to something else (Blu-ray H.264 at 29.97), and then re-encode that file to Pro Res HQ with either compressor or adobe media encoder. The problem lies in exporting progressive footage as interlaced, it just completely screws up the frame rate. The worst bit is that, I need Pro Res HQ for the distribution house for the commercial spots, they require the ProRes HQ MOV at 29.97i and if anything is off, I get charged for it.
Does anyone else have problems with Adobe Premiere lacking on the professional end? Or similar experience with this problem?
Just do a search for pro res frame rate issue premiere and you will see a lot of other users with the same issue.
Thanks,

Final Cut Pro dropped frame rate issue

Hi there, i currently shot a short film on the canon 5d mark II 30fps and i am trying to edit it in final cut studio 2. I have recently bought the new macbook pro 15inch 2gb module.
Now the canon footage is h.264 but when importing the clips into final cut pro 6 there is a lot of dropped frame rate issues but I thought this machine could handle HD footage?
Can someone more advanced than myself recommend what i am doing wrong or a work flow that i can work with to stop dropped frame rates and render times.
Last piece of information, the project will be entered in film festivals in the spring its only a 3 minute short and i have 5 folders of footage under 4gb each which was taken from the camera
Thanks for your help.
Michael

You are missing a huge conceptual point. If the file can not spool off of the hard drive fast enough, you get dropped frames. It isn't a processor or ram issue right now, it is a hard drive speed issue. Your system drive is overtaxed trying to run OSX, applications AND spool video. It just can't keep up. Changing the graphic card isn't going to help (and how do you change the card in a laptop?)
Get an external esata drive - with the new MacBookPro you'll need an esata Expresscard34 adapter for the computer to connect the drive. Firewire is not an option with that machine and USB2 will not cut it with high data rate formats like ProRes.
When you drop in the ProRes clip to the timeline and it tells you there is a mismatch, this means your preset for the timeline is something other than your clip. You WANT ProRes and you need the sequence to match your clip - tell the program to CHANGE the sequence to match the clip.
Video is not easy and it isn't inexpensive. Time to open up those manuals and your wallet!
Good luck,

DVCPro HD frame rate issues

I'm sure that this question has been asked before, but I performed a couple searches and couldn't find a thread to perfectly answer it.
I have a tape that was shot (with the Pansasonic HDX900, shot to tape and not P2) at two formats, 720/24P and 720/60P. Most of the tape was shot at 24P, but the cameraman shot a few minutes shot at 60P to create slow motion. Both 24P and 60P are on the same tape. I am capturing directly from the camera, not from a deck. I have a couple issues:
1.) My device control through FCP does not seem to be working, so I can only capture with "capture now." My device control setting seems to be right (DVCPro Firewire), and I've tried to restarting FCP and the camera. It doesn't seem like this is a trash-the-prefs issue, so does anyone have any thoughts? I have driven the camera's deck through FCP before.
2.) What is the best way to work with the different frame rates? Right now it captures at 60P no matter which capture setting I have it set at (when shot at 24P it duplicates frames to make it 60P). Is this a result of mixing formats on the same tape?
I'm a little lost, thanks.
Stef

It doesn't have that function and after consulting the manual (again) I am beginning to believe that playback control is only possible internally to the camera, rather than externally from another device. It doesn't explicitly state this, but the manual DOES specifically mention the record start/stop functions but has no mention of playback start and stop.
That said, the larger issue at the moment and for the future is the frame rate issue.

How can I change to a higher frame rate than 12 FPS?

Just got a good deal on a 15 in MACBOOK Pro running Yosemite with the latest Quicktime and iMovie. Is the best frame rate I can get out of this HD camera 12fps? I can't find anywhere to change it in QT or in IMovie.

So you seem to correctly understand the information in the linked Use More Light! article.
studiojl wrote:... I don't like that at all...
Your emotion is irrelevant. It simply works the way Apple software is written. Perhaps some other computer system works different from Mac OS X and Apple camera apps?
If you intend to keep using Mac, you can take manual control of some camera parameters by using a third party add-on app such as iGlasses, Webcam Settings, or Sight Control.
studiojl wrote: ... what frame rate does it pick if I import one 30 FPS clip and one 60 FPS clip?
Whatever frame rate is set by the program of the software application you are using to record those clips.
You can determine that frame rate by making short test videos and watching it in QT Player.
The QT "Inspector" window will show you the frame rate for the clip.

Speedgrade frame rate issue when loading reels. EDL from Premiere CS6

We have a short film, cut in Premiere (time base in sequence is set to 23.976 and display format is set at 24fps) I imported the EDL into Speedgrade for coloring. My Speedgrade edit settings have a base frame rate of 24fps and the option "both edits have current base frame rate as set above or within the EDL itself" is selected. However when I go to load reels from desktop I am getting an error that says "some of the reels do not match your current frame rate." In turn this is causing our exported Quicktime (TIFF uncompressed at 24fps) to not sync up with our audio back in premiere. It looks as if we are missing frames.
Is this an EDL issue with Premiere? Or is it a Speedgrade frame rate settings issue? Any feedback is greatly appreciated!
Some details on the project:
Shot at 4K on Red Scarlet, at 24fps. Edited in Premiere CS6.
Premiere Settings:
Editing Mode: Custom
Timebase: 23.976 frames/second
Display Format: 24fps Timecode
Speedgrade Settings:
Timeline FPS: 24fps

I don't have had problems if the frame ratio is the same in all process, and in this case it isn't. If the Scarlet footage is to 24 fps, why to use 23.976 in Premiere?

Frame rate issue

Has anybody else had problems getting after effects to interpolate the frame rate acurately on import of a 24p file? I have exported a quicktime and dv24 avi out of premiere in 23.987fps and when I import into After Effects it assumes it is 29.977fps. I have imported the file back into Premiere to double check that the files are 23.987 and it is. Is this a bug?

It's not really a bug, but more like an omission.
AE uses a text fille with information on how to interpret different footage types. The problem is that SD 23.976 progressive files are truly recorded as 29.97 with no real way to tell them apart except for a flag added by the editing application used to capture the content (assuming it's tape-based). AE can't see this flag automatically at this time for this kind of footage items.
So, if you have (say) 30 such footage files in your project, this would be a fast workaround:
1. Select any of the 23.976 fps files, right click and go to Interpret Footage > Main (or press the new Interpret footage button in CS4, at the lower left corner of the project panel).
2. In the remove pulldown menu, choose one of the 24P/24PA options (24P or 24PA depend on the camera and/or recording mode set in the camera).
3. Still with the clip selected, right click and go to Interpret Footage > Remember Interpretation.
4. Select all other 23.976 fps clips, right click and go to Interpret Footage > Apply interpretation.
This way, you could correct the intrepretation for dozens of items in 30 seconds. It's still a workaround, of course.

FCE4 and frame rate issues

Hi All,
I'm totally new to FCE and video editing in general, and have dived in with two feet. I'm trying to edit some screencasts I have produced. My main aim is to cut out dead sections of the screencast and add a voiceover to them. I tried various screencast-specific bits of software, but they didn't seem to allow much in terms of editing, and one (Camtasia Mac) decided to eat a day's worth of work by corrupting the saved file.
So, I thought I'd grab a copy of FCE and give that a try. I've bought Tom Wolsky's FCE4 Editing Workshop Book (whose name lead me to this forum). I was also quite interested in the voiceover feature that FCE has, as that should come in useful as that is the main reason I'm editing these screencasts in the first place.
The main issue's I've been having is that FCE is intended for DV editing, and I'm trying to edit a screencast, so I'm going slightly against the flow here. e.g. my screencast was captured using QT X at 1024x768. Which FCE can't deal with (I only found out after buying FCE... I head FCP can deal with non-DV standard frame sizes, but it beyond my budget). So I've been using MPEG streamclip pretty successfully to convert the H.264 source into Apple Intermediate scaled down and padded to 1280x720. I can then export from FCE back into Apple Intermediate and into MPEG Streamclip to crop off the pillarboxes and save to the final output format.
I've come to the conclusion that as long as I can get my source material into what FCE expects from a DV cam then it seems to handle it OK.
Some of the test clips I imported into FCE seemed to work fine, but then the longer full length source (about an hour) had trouble. The speed had gone all funny. I looks like the screencast source is at around 4.6fps and FCE decided that it should really be 46fps! One of the test clips appeared to be 5fps, and FCE seemed to be OK with that and kept it at 5fps.
I'm currently re-converting the source with MPEG Streamclip to 29.97fps and hopefully that will import OK (even though it is taking ages to convert and I'm writing this sitting here patiently!).
So was wondering if anyone know what the deal is with frame rates in FCE. Why does it sometimes seem happy with my low 5fps rate, and sometimes it decides it should be 10x faster. And does anyone else have any further comments or suggestions/tips about using FCE for editing screencasts?
Thanks,
Matt

Tom, thanks for the help. I'm currently running it through Streamclip now as I type. Hopefully that should sort it. I guess screen capture software use a lower frame rate as they don't need to have a high frame rate usually for the stuff they are doing.
-Matt
PS. btw... great book! Certainly helped me get orientation around FCE. Definately needed as I had no experience of video editing and the workflows and terminology is all foreign!

Frame Rate Issue on ATV3

I've had my ATV3 for about 8 months now. I use it very often to stream HD content from my computer. I do this over iTunes via Home Sharing. It was working great, but recently I've noticed it's suffering from jerky frame rates. It's not constant, but when there's lots of movement on screen, the screen stutters occasionally. This problem does not occur on netflix or for lower quality content over homesharing. It's a recent problem insofar as the same videos would play fine for the 7ish months of usage.
It's not a buffering problem either. The movie has loaded, the screen just stutters in sections of videos with lots of movement. Anyone have any ideas on what the problem might be? Is my ATV3 wearing out from only 7 months of (extensive) use? Perhaps it's related to some updates? Afaik the issue did seem to coincide somewhat with installing some updates, although I cannot say for sure. Thoughts? Potential solutions?

Found this, applied it - and it works.

Re: ATV3 framedrops after 6.1 update
Mar 23, 2014 5:53 PM (in response to YannieNL)
If you have one of the original Apple TV 3rd generations you can downgrade to a firmware released in June. Apple released a small revision in 2013 that they didn't announce. You can't even tell by looking at the ATV.
http://www.idownloadblog.com/2013/01...minor-upgrade/
If you have the 3,1 version Apple is still signing an older version software released in June. Google "Apple TV Firmware Links" and it'll be something with "xxx.icj.me/xxx/xxxx" for an address. You can get the older version from there. It's the one with a green check mark (6.1.4 is what it's listed as) I'm not going to link the site because I don't think Apple allows that on their own forums. Just downgraded my ATV and it's working like before now. You'll need a microusb and the power cord.
1. Open iTunes
2. Connect ATV via MicroUSB
3. Connect Power Cord
4. When ATV shows in iTunes hold 'Option' and click restore then point it to the old FW you downloaded.
Worked for me. Hope it works for some other people."
Not the most elegant solution but a solution none the less.

GE60 20C frame rate issue

I bought a GE60 2OC recently and i have been having a very low frame rate while gaming.
Whenever i play for example black ops 2 i get around 20 frames while on low settings.
i have installed the drivers included with the product but i was wondering if there are any additional drivers i should install from the msi website.

the problem im having is a bit different and im an amateur at this and not capable of understanding all of it.Because i only have been using it for about 3 days I was considering returning it seeing as it had this issue from day one,i think that it might have been faulty from the beginning.
on a other note does anyone know where the product serial number is located on this product because i don't seem to be able to find it anywhere on the notebooks surface.

Problems editing ProRes 422 in FCPX– ? Frame rate issue?

I cannot edit video I import into FCPX except by using the Proxy media option in preferences.
I'm recording video from my HCX920 camcorder to Apple ProRes 422 format with Wirecast as the recording app during simultaneous live broadcasting.
The Wirecast encoding settings are set at: ProRes 422; 1920x1080; 29.97 fps for video and the audio is encoded as 24-bit integer; 48kHZ; 16-bit sample rate.
The video feed from the camera is 1080i at 59.94 fps.
The raw video file is identified as "Apple ProRes 422, Linear PCM" in Get Info. In QT 7 the FPS is listed as "29.81" Playing fps with the movie playing ranges from 28-30fps.
After I've imported the video to FCPX the "Project Properties" shows the video to be "1920x1080 | 59.94p". It seems that FCPX is importing the video recorded at 29.97 as if it were recorded at 59.97fps. Is FCPX transcoding my video to a higher frame rate?
I am unable to play the movie once it is placed into the timeline. It immediately stutters and shows the dropped frame warning. I am running FCPX on a Quad-Core Mac Pro with 20GB of RAM. The only way I can play the clip is by creating proxy media and choosing this in preferences.
What am I doing wrong? Any help will be greatly appreciated.
John

Kevin,
No, I was never able to get this problem worked out. It caused me to pull my hair out. When I compared the video quality of the ProRes output from Wirecast with the video recorded in AVHCD format on my camera's SDHC card the difference was dramatic. So I've stopped simultaneous ProRes recording in Wirecast and I now import the AVHCD material into FCPX from my camcorder's card.
I do, however, record the audio from my Wirecast broadcast and synch it with the video from the camera. The audio captured by the camera's built in mechanism is abysmally poor. This causes me more work but the final output is far superior to what I was getting from my Wirecast recordings regardless of format.
I wish I could help or offer more encouragement.
John
