On Snow Leopard (10.6), the screen recorder on QuickTime Player worked just fine. However, since I have upgraded to Mountain Lion (10.8) QuickTime screen recorder has been making my 2010 MacBook Air extremely slow/laggy while recording the screen but once I stop recording my computer is no longer slow/laggy.

I happened upon a tutorial that showed someone using VLC to screen capture on a Mac and decided to give it a try. It turns out that functionality was removed from VLC on Lion and Mountain Lion and the reason was provided in this this thread: Mac OS Lion, VLC screen capture does not work:

Apple completely removed the API to capture the screen and replaced it with something totally different. Until anyone steps up and implements the new one, this feature is not available to Lion users. It remains accessible to Snow Leopard and Leopard users of course.

Available on the App store for $10 and records w/o performance issues. I was skeptical at first, so I downloaded its trial, and was extremely happy with the performance. $10 is definitely more than free, but depending on how often you need to record your screen, this is well worth the money in my opinion.

It supports both JPEG and H.264 encoding, but only records up to 25fps. For audio, it allows you to select which input and even allows you to use the computer audio (something QuickTime didn't allow and you had to use a separate utility like Soundflower).

I believe that Apple has upgraded Quicktime's API's for high definition beyond 1080p etc. There is nothing wrong with quicktime per se. It's just laggy with older macs. Maybe faster SSD, more Ram might help?

A common issue I've seen here. When exporting a sequence from premiere the color shifts dramatically in the majority of playback programs. Quicktime, Vimeo, Youtube etc. VLC works fine but not everybody is using VLC. Makes for lots of wasted time on color grades.

A feature for handling this issue - adjustable Viewer Gamma - has been added to Premiere Pro v24 and is explained in this documentation: -pro-ideas/quicktime-gamma-shift-prevent-color-shift-on-expor....

Been dealing with this for years. Best I've figured out is to make sure directors and clients use VLC to do their official reviews (esp if reviewing color). Not ideal, but I've got nothing better! arkalmed is on to the real fix there, just need to make engineers aware of it.

That Vimeo from Baselight is one look at the issue. It's not necessarily accepted as an accurate view, though, by many of the other folks out there in color management. One significant misreading is typically cited. Whether by Steve Shaw at LightIllusions or others.

That video assumes that the original Rec.709 standard from many years ago is still the entire standard. But it hasn't been for years! Not since flat-panel digital monitors replaced CRT monitors. The digital monitors had a very different image from the 'native' digital signal. They therefore required either the additional spec of a display gamma or a change to the camera transform process.

This workflow was the accepted manner of working with NCLC tags of 1-1-1, and the monitors were carefully calibrated and profiled to the above display specs. It's what both Resolve in "auto" mode and Premiere Pro applied to Rec.709 files.

Apple chose to return to the original Rec.709 spec and ignore the Bt.1886 appended specification. Think of this as "the real Rec.709," ... but Apple changed that years ago. And applied throughout professional workflows.

I know quite a few want to be able to easily mod the files to get around the Mac display issue. And well, if someone wants to, and understands the other problems that choice may cause, it's their file. I'd always go for more user options. (No matter how wise they may be at times in certain uses.)

Any updates on this? Ive been having this problem for about a year or two now. Happens whether I export from Premiere or After Effects. Exported footage looks totally fine in VLC but totally washed out in Quciktime on my Mac Mini. Then sent it to my Macbook Pro and its the same thing. I even tried viewing it on my iphone and it was washed out there as well. So the only time it looks okay is in VLC or if I bring the footage back into Premiere or After Effects. So essentially nowhere that someone is going to view the video when I send it to them. This is so infuriating. And I see so many solutions that are just adding new LUTS to correct this gamma change (or whatever it is) but if or when this issue is ever fixed, then that footage with the lut is going to look too contrasty. So do we just make 2 separate exports of all our videos now? One how it was originally graded (but will be washed out in Quicktime and all devices but look correct in VLC). And the other one with the corrected edits/lut (will look correct everywhere except VLC and if you drag back into Premiere/AE). I don't understand how I've never run into this issue with 10-15 years of editing/coloring experience, or has it really just flown under my radar?

I work for/with/teach pro colorists. So I've been through HOURS of presentations and discussions on this, in person and over zoom/whatever with high-end colorists. And with the people that make the calibration software used by the colorists.

And as Fergus and other staffers will point out, Adobe has given you some good new options in 24.x. But before you choose, you need to know what happens depending on your choice. As in ... you get to pick your poison.

Adobe can't "solve" this, though they've given you choices now. BlackMagic can't solve this, they give you similar result choices. No colorist can solve this. Only Apple could 'solve' this for all users across platforms.

Thank you for explaining. I'll have to update my system so I can run Premiere 24 because those changes really sound worth it. I started viewing random video files on my mac and comparing them in Quicktime and VLC to see if theres any difference or if its just videos I've exported from Adobe software. To my surpirse its every single video, totally raw videos that were never imported or exported to Adobe. Every single video I watch has a different gamma in Quicktime vs VLC. So is that just because of Mac's Color Utlity controlling Quicktime? Its just crazy to me that the same file will never look the same between those two programs.

QuickTime player never ceases to catch your eyes by causing endless troubles. The most common problems include QuickTime won't open on Mac, quicktime can't open MOV, MP4 files, quicktime not screen recording on Mac, quicktime quit unexpectedly, etc. Confronted with those troubles, go to Apple support for official solutions. Yet, apple community doesn't cover everything you need. Instead, the solutions that have been tested first hand by a wide number of users are more reliable and comprehensive.

Here this post gathers all the effective solutions findable right now on varied types of forums, answer websites and communities, aiming to help you out of the off-putting QuickTime not working on MacBook, iMac troubles. Check the specific solutions if you don't wanna waste time hunting high and low in umpteen websites.

When the QuickTime Player quit unexpectedly error pops up, tap Reopen to close this dialog. If nothing positive happens, check the storage space on your Mac laptop. The shortage of free storage space will render QuickTime Player quit unexpectedly error on Mac.

The File Isn't Compatible with QuickTime Player? Why does QuickTime player not open my files on Mac? This kind of problem has been mentioned on the various forums and answer websites at highest frequency concerning QuickTime not working on Mac errors. The major cause lies in that mp4/mov codecs are not supported by quicktime.

As is known to all, MP4 is a container format, which can consist of varied types of video audio streams, subtitle tracks, metadata, etc. Once one of those codecs is incompatible with QuickTime codec ecosystem, video won't open in QuickTime media player on Mac.

To fix QuickTime not opening MOV MP4 files issue, you can download quicktime video codec pack as a workaround. Of course, be aware of the potential adware & malware hidden in the video codec package.

Or resort to a better yet more safe way - convert MOV/MP4 to QuickTime supported video codec/format. The professional video converter from the leading company Digiarty Winxvideo AI works like a charm in this part.

Step 2: Choose Mac video format. Pop up the Output Profile window by clicking on the Target Format option at the bottom, andd select MOV H264 as output format. You can also select converting MP4 video to Apple ProRes codec, iMovie video format (MPEG-4 or H264), Final Cut Pro format, as well as iPhone iPad Apple TV formats under Apple Device subcategory.

Note: tap the setting icon on the main interface and then you're allowed to adjust MOV MP4 video resolution, frame rate, bit rate, video profile, aspect ratio, etc. to make video playable in QuickTime without asking too much on computer hardware configurations.

Step 3: Convert video to QuickTime video codec/format now. Hit RUN button and the conversion engine will go into action. The whole procedure will run at GPU hardware accelerated speed, 5X faster than those without GPU acceleration tech.

Greeted by the error message "The QuickTime Cannot Record, try recording again" when recording Mac screen video with external audio? To fix this QuickTime not working on Mac error, resort to a new external microphone. Or switch to the internal audio to have a check.

If this still doesn't work, check your QuickTime player if its version is too old or outdated. Consider upgrading QuickTime player to the latest version to improve its compatibility with your macOS operating system. Then, check your audio driver version and see if it needs a upgrade, as well.

Solution 2. Go back to check if the playing video you're screen recording allows you to free capture. For some videos protected by DRM encrypted protection, it only allows you to capture the very beginning and then causes varied types of errors, recorder freezing error included, as well. If so, give up recording the content protected screen video. Instead, legally screen capture the content that is DRM-free.
