Lagging Video Output

Hello world! It's my first post here. I've encountered a problem. When I export a video, the exported video files are always lagging. It won't play smoothly. I don't know why. I've tried to play around with the frame rate with no avail. What's the cause? Please help! Many thanks!

Chris,
The biggest problem is that the behavior that you describe, or similar, could have many causes. That's what Harm is trying to narrow down. With playback issues, it could be:
1.) System, especially the I/O sub-system, i.e. HDD's, and how they are allocated.
2.) Assets - what you're using as source footage
3.) Project - what Presets you are working with, and also the settings for Export
Without the answers to those questions, no one has anything to go on, and all we can do is say, "it's your system," or "it's your Assets," or "it's your Project Presets." That will not help you. With details, someone will see the possible problems, and be able to give you tips on how to eliminate the problem, or narrow down the possilbe causes.
Good luck,
Hunt

[SOLVED] Faulty video output with mpv/mplayer, vaapi

Hi,
I have a HD6870 with the proprietary catalyst drivers installed, and the packages needed to enable vaapi. The problem I have is that every video application like mpv, mplayer or whatever refuses to give me correct video output with vaapi. mpv for example gives me these errors, depending on filetype:

mpv doesn't crash, it just falls back to software decoding and gives me a grey screen when it's not fullscreen, and when it's fullscreen it tears a lot and flashes random grey stripes everywhere - sound still works fine. Any ideas on what can be at fault here? The only video output that gives me an OK image without tearing or anything else is x11, but it's really slow.

Now try vainfo again. Instead of "Splitted-Desktop Systems XvBA backend for VA-API - 0.8.0" it should say "AMD MMD 1.0" or something like that.
Thanks, now VA-API at least gives me an output - but the video just flashes in fullscreen. I think another thing to notice here is that the video only plays correctly (gives me an output), if I play it on monitor 1 (I use three monitors) - but I can't get rid of the screen flashing.
EDIT: Fullscreen only flashes when I use mpv, with smplayer (+mpv) it works ok - but it lags from time to time. mplayer-vaapi won't give me a smooth playback either with -vo and -va as vaapi, and the screen also flashes when I'm using it.
Any idea on what's wrong? Is it my use of three monitors? This is really, really annoying.

How connect a 27 cinema display to HP Pavilion with VGA video output

how connect a 27 cinema display to HP Pavilion with VGA video output

If it is a thunderbolt version of the apple 27" display, you don't. The TB displays can only work with a TB source.
I also think you are out of luck with the mini-displayport versions of the apple 27" as well. This would imply converting an analog VGA output to a digital input of the 27". I suspect that there is not enough data supplied by VGA for that to work and I do not believe any adapters exist for this.

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
Thanx

I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...
thanx

Vga or dvi to video output to NTSC TV viewing

GEAR: I have a G4 dual 1.25 (silver double doors) with an ADC and DVI output in the back.
OBJECTIVE: I need to go from that to an NTSC TV so I can see what my edits look like.
NOT SURE: I have seen the Apple adapter (http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/7200505/wo/0K4TK pkMz7f922WszZYxFQMUy31/1.0.19.1.0.8.25.7.11.2.3) but it says it is for the MAC mini and the G5 only... does that mean it won't work for me?
OPTION B: Is getting a video card with an RCA or S-video output a better idea? If so which one? I am using both the ADC and DVI ports for two monitors, but would nuke one if necessary because I have to get this TV viewing capability up and running.
OPTION C for CANOPUS: I have also thought about the Canopus ADVC 100 or 300 so I can capture video from sources other than my DV Sony DSR-30. Right now, I have to record everything (everything that isn't DV) to DV on the DSR-30 before turning around to send it via firewire for capturing in FCP. Would the Caopus ADVC 100 or 300 also solve the TV viewing problem as well?
THANKS: in advance

Firewire to a DV/analog converter to your NTSC monitor. The only way for DV.
the DV/Analog converter can be either a dedicated converter (eg Canopus), a DV VTR deck (eg Sony DSR-11) or a camcorder.
the other options are not what you need.

TV (video) output from new nano looks very good!

Just a comment for those who may be wondering how the video quality on the new iPod nano looks when output to a TV. I have one of the old iPod AV docks with the s-video port and the new nano seems to work fine with that combination (using a standard s-video cable between the dock and the TV). Thus far I'm really impressed with the video quality, I can't see a single problem, the color is good, the quality and sharpness is as good as I've seen from any iTunes Store content, and as far as I can tell the frame rate is fine (no stuttering, skipped frames, or problems with audio sync). I'm amazed that such high quality video can come from such a small device. If it continues to look this good (after viewing more content and after more testing) then I think Apple may have "hit one out of the park." This thing could turn out to be the most popular iPod yet (if you have any interested in video and still want a small device).

I just found out that the video out (TV) on the new nano supports video playlists so you can create playlists for back-to-back display on the TV. Not even the AppleTV will do that (even though the latter has been a highly requested feature for the AppleTV since day one). In fact, if you can do without the on-TV menus you may find that the nano is a better video output device than is the AppleTV (that is, the menus system on the nano doesn't appear on the TV output).
Also, I just competed a few hours of video playback to my big-screen TV from the nano and I'm still impressed. No video problems at all, looks very good considering the quality limitation from the content that is currently on the iTunes Store (limited to standard definition, no HD movies, HD TV, or HD music videos as yet).

Video output failure

I have a 2008 black MacBook, a Mini-DVI-to-VGA adapter and a Mini-DVI-to-"Video" adapter (AKA a Mini-DVI-to-RCA-and-S-Video adapter). The -to-VGA adapter /was/ working fine.
After I got the -to-video adapter I was having some problems making it work. A few places said I had to set it to 50Hz (which makes no sense as NTSC is 60Hz, but anyway), but that option wasn't available to me. I poked around, and apparently made the video out go completely insane. Now, when I plug in either adapter (regardless of whether anything is plugged in to them), the screen goes blue for a moment as if it's detecting a new display, but then it just goes back to normal with no new display detected. Running "detect displays" manually makes no difference, and neither does having something plugged in on the other end or not.
At this point, I can't use video output for any purpose, which is sort of annoying ...

My new (2 weeks old) Macbook Pro, wont send video output signal to beamer... What can I do? I have the adapter to vga but it does not work...

Hi, I have a new MacBook Pro and I dont get video output to a beamer although I have the regular
Mini DisplayPort to VGA Adapter and it works fine with my older MacBook...
Thanks a lot for your tips...

That should work. When you first hook it up it will probably have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In SystemPreferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.
If you also want audio you'll need audio cables to the TV using a 3.5mm stereo headphone jack to RCA sound plugs. You attach it from the headphone jack of your MacBook to the appropriate input plugs on your TV http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=min i-dvi&x=9&y=13#/ref=nb_sb_ss_i_2_19?url=search-alias%3Daps&field-keywords=macboo k+audio+cable&sprefix=macbook+audio+cable&rh=i%3Aaps%2Ck%3Amacbook+audio+cable

MacBook Pro to TV, Video Output Too Dark

Hi,
I have an 2010 model 15" MacBook Pro i5.
I got this video converter for Christmas:
http://www.amazon.com/VideoSecu-VGA2TV-Computer-Presentation-Converter/dp/B000X3 FAJU/ref=sr14?ie=UTF8&qid=1295210644&sr=8-4
Using this in conjunction with an Apple Mini DisplayPort-to-VGA adapter and a standard RCA video cable, I am able to connect my MacBook to my TV so I can stream video from sites like Hulu.
My TV is a Sanyo flat screen CRT that's, probably, 6-7 years old (exact model probably isn't important).
I have no issues with the quality of the video output I'm getting (i.e. resolution, color). The issue I'm having is that the video is too dark. The video looks great on my MacBook screen, but the TV display is too dark. I have tried playing with the settings on the TV and on the converter (through which I can adjust brightness, contrast, saturation, hue, and sharpness) and I can't, for the life of me, get the output to my TV brightened up to an acceptable level.
I have tried to use the display calibration tool in the Mac's display preferences and that didn't seem to help (I'll admit that I don't think I'm doing it correctly).
Can anyone suggest some steps that I might try in order to improve my video output?
Thanks.

S-video output B&W

Hi,
From time to time I like to connect my PowerBook to TV thorugh S-video (using adapter S-Video to scart) to watch movies with friends etc.
Though, it has been some time (over half a yar) when I last watched a movie on TV that way. Since I know for sure that I have been able to connect my pb to tv via s-video with no problems I can't understand whats wrong now.
Here's the thing. When I connected my PB to a TV now, it shows the picture in black&white on the TV. Anyone know how to get back the colour image? I have the same cable set that I used before to connect to tv (latter is the same one also) without any problems - full colour. So, I think the problem is software-related (maybe os x update).
Can anyone recommend what to do to get the colour back?
cheers,
r. pello
P.S. PB's lcd screen works fine. So, problem only with s-video output colour.
PowerBook G4 (1.67 GHz, 15") Mac OS X (10.4.9) iMac (Summer 2000, 120GB HDD)

Have you checked the resolution/TV type in the Displays preference pane once the TV is connected? If your PB is detecting your TV as PAL rather than NTSC (or vice versa), that could certainly cause a loss of colour like you describe.

IMac g5, no video output

I just replaced the logic board and power supply on my G5 imac, both of which were bad. Now, when I power on, all three LEDs on the logic board come on, t there's no video output. The video had been working fine before the logic board and power supply failed.
THe tech note says to try resetting the PRAM. We have a wireless (usb) keyboard, and holding down option-apple-p-r doesn't seem to do anything. Is there another way to reset the pram?
Any other suggestions would be welcomed. Replacing

THanks Moke.
OK, I bought a wired keyboard and tried to reset the pram. I think it worked -- it rebooted the computer and the chime came on again. But there's still no video output. Not sure if that means I should replace the screen or the video inverter or both or if it could be something else altogether.
Any ideas?

IMac G5 iSight - Resolution problems when using s-video output.

Good afternoon all.
I have an iMac G5 and the only video output it has is a mini VGA socket. I have used this with a mini VGA to S-Video converter cable from Apple and am getting some odd results.
The Mac is running Leopard 1.5.7 and I'm outputting to a fairly old Panasonic CRT TV.
The problem I find is that when I plug in my mini VGA adaptor to the Mac it reduces the resolution on the Mac screen down to 1024x768 (stretched). The TV outputted TV image looks great, but I can't seem to keep my native resolution of 1440x900 on the Mac display.
If I do go and change the resolution in "displays" in the sys' prefs' then it just seems to keep the 1024x768 resolution on the Mac but this time without stretching it.
Does anyone know how I can keep my Mac at its native resolution of 1440x900 while still outputting to s-video to the TV?
Any and all help will be greatly appreciated.
Thank you again in advance.
Stuart

Hi
I have the same config as you: I have been using it for years to view on my tv dvds or videos from the web.
To my knowledge there is no way to acheive what you wish: when you plug the adaptor in the mac adjust to your output source and its main display (the g5 display) will reflect that with the result that it becomes very difficult to use.
Maybe there is a way to try changing the resolution in a middlle"configuration" which would give an acceptable viewing on the tv as well as on the g5.
Personally I keep plugging and unplugging the adaptor as needed.

Lost S-Video Output

I have been using a G4 Powerbook 17-inch, 1.33 Ghz connected to an NEC VT470 LCD Projector through the S-Video output (Mirroring). It had been working just fine until recently - the s-video output stopped working. The odd part of this is that if I connect through composite video and the s-video to composite adaptor,It works. I have confirmed that the s-video input of the projector works, and i've tried the same thing on a 52" DLP rear-projection TV with the same results - composite video through the composite adaptor but no s-video straight through the s-video output. This makes me wonder if there's just a setting that's been changed or turned off. Another note: the Powerbook will not "detect" the projector when connected through s-video, but it does when using composite through the adaptor. Any ideas?

That does sound like a faulty video card - I just read another post regarding faulty video card - in that case replaced under warraty by Apple.

T61p S-Video Output?

Hi,
I know the T61p doesn't have an S-Video output, but can a VGA to S-Video adapter be used with this laptop? Such as what is shown here: http://www.amazon.com/NEW-CONVERTER-S-VIDEO-CABLE-ADAPTER/dp/B000S675JU
DaHunter

From amazon reviews:
"The other reviewers did not read the first sentence in the description. Your computer MUST have TV-Out capability for this cable to work, which is rare. You cannot simply connect this cable between your computer and TV and expect to get a signal. It's unfortunate that this product got so many 1-stars due to customers not doing their homework.
This cable works great if your computer has the TV-Out capability but if it does not, then you must purchase a VGA to S-video converter in the $30-60 range"
Imho you'd better off with something like this:

Have you tried holding the Windows key and tapping the P key?
As there is no support for Windows 7 for your laptop by HP at this writing, this may indeed be difficult.
Have you checked in Device manager to see if any drivers have a yellow exclamation mark next to them?
