Any flash video I play in fullscreen in ML is choppy and unwatchable. This was not the case in Lion. And yes, I know I shouldn't be using Adobe Flash, but some sites demand it. Anyone else experiencing this, even better, a fix?

Nope, no issues here; perhaps you should reinstall flash?

Thanks for the tip, but no luck. I've noticed that if I change my monitors rez to 720p from 1080, the playback is alot smoother. Anyone got any suggestions?

EDIT:

I fixed it. Right clicked on a choppy flash video to see the 'Flash Player settings' menu. I clicked on the 'Enable Hardware Acceleration' toggle, and everything back to normal. :)

Glad to hear that. Was it unchecked by default?

This has been a problem for me too. Originally on Lion the solution was to disable hardware acceleration. I tried the same approach on ML, but it no longer works for me, even on latest version of flash and clean ML install.

Regular video e.g. non fullscreen works fine, no lag at all. Anyone else come up with a solution?

I've been enabling it in Mountain Lion instead of disabling it, try that perhaps?

Maybe a software conflict have you installed perian?

No plugins installed. Clean install aside from Flash. Enabling or disabling hardware acceleration does not solve the problem.

I may try disabling safari extensions. Presently I only run 1password and adblock, so I would've thought it was unlikely, but I will check it.

That said, any other ideas?

Note that you should restart Safari (I presume) or your browser of choice, after changing the 'Enabling Hardware Acceleration' setting, for the change to take effect.

Oh, I was unaware it required a browser restart. Will try, but I think the problem persisted when I tried that.

My results are spotty. Sometimes fullscreen is fine with hardware acceleration enabled, but come out of it and go back in and it lags. :(

I've only been using OS X for about a year now, and only for the last 3 months or so exclusively at the house, but I'm curious about this comment. Why shouldn't the OP be using flash? Is it because of the whole malware thing a month or so back?

Thanks,

Jerry

Flash shouldn't be used because:

1. The most frequent causes of crashes on Macs.
2. The most likely cause of a security exploit.
3. Incredibly poor performance and memory usage (99% CPU at times).

Steve Jobs was absolutely right. Flash is an abomination, certainly on the Mac. The sooner streaming sites replace it with native HTML5 video, the better.

Thanks for the information. What is the best alternative then when a site tells me Flash is required?

Thanks,

In Safari you can install an extension called 'ClickToFlash' which automatically stops all flash from loading (until you click on it), but it also comes with a built in HTML5 player that will enable wherever possible. You can get it by clicking the Safari menu, and then the 'Safari Extensions' option.

Sadly there's no direct alternative. YouTube has really helped push HTML5, but virtually all other streaming services are predominately flash related e.g. PutLocker, and I also think paid streaming services too.

The problem, or rather it isn't a problem, but the content producers say it is, is that HTML5 video is completely open. There's no way of securing content. Flash gives you that as does Silverlight, but as you might expect, they both suck.

Fix!

I've been banging my head against the wall for 24 hours now and this works for me.

I have an old MacBook Pro, 10.6.8, newest version of Chrome, Safari and Firefox, and a new Focusrite USB audio interface (Scarlett 2i2).

Installed the newest Flash player (11 something) and the Focusrite yesterday and everything went bad. Choppy fullscreen video, no audio in Chrome etc etc. So anyway, now it's all fine:

MAC/FLASH: Choppy video, no audio FIX.

1. UNINSTALL FLASH PLAYER. It sucks.

2. Bin the whole Macromedia folder from ~/Library/Preferences.

3. USE CHROME FOR FLASH SITES (has built in flash player - close Chrome when not in use to shut its flash player, to save CPU power).

4. ALSO: Have a USB audio interface? AUDIO MIDI SETUP: 44.1kHz OUTPUT.


That's it. Everything is now smooth in fullscreen in Chrome, and great audio through the Focusrite box.
*fingers crossed*

I've got one of the newest macbooks running 10.8 and seemingly out of nowhere, I'm encountering the exact problems detailed here. In any full screen flash video, the video suddenly becomes very laggy and choppy.

I'm running up-to-date Chrome and Flash, and I've also tried the "Enable Hardware Acceleration" fix (which was already checked) but to no avail. Does anyone else have any ideas?

So I decided to not be a leech and share my fix (signed up here just to post this answer)...

Not sure if this is still happening to anyone and maybe my problem was isolated but I fixed the issue on my machine and thought I'd share...

I was having MAJOR lag issues with streaming video online on my machine. To the point that the videos were unwatchable because of the jittery, choppiness, and generally overall poor performance.

After troubleshooting for an hour I found that MY problem was stemming from a google chrome issue. I am all fixed now and here is where I found the solution.

https://productforums.google.com/for...me/zRDBYF_yLdE

Make sure you restart Chrome once you've followed the instructions for the fix to take affect.

Although I know some people have way larger issues then just a crummy flash setting on Chrome but I hope this helps someone...

See my reply above... so frustrating but this will fix your problem!
