Will Quick Time Player 7 work under El Capitan?

Yes, it does.

The replies are not entirely true. Although the player "works" it lost some functionality. You no longer can play a movie saved with an adjusted brightness in QT 7. The movie opens in a blank black screen. Only when you adjust the brightness back to 0 it will be playable. The movie will still play in QT X, but saved brightness settings will not be in affect. This is a huge minus considering that QT X STILL doesn't have any A/V adjustments functionality of QT 7.

Partially true. I had no trouble adjusting the brightness or any other slider in QT 7 and playing it back. All adjustments played all the way through. QT X does indeed ignore all such settings.

Doesn't work for me. If I adjust brightness on the clip even just a little bit and then try to play it then the clip becomes totally black if I make it darker, or white if I make it brighter. I reinstalled QT 7 but it didn't help. I'm opening videos shot on various iPhones.

Since the adjustments QT 7 makes are only attributes (not physically rendered to the video), any app that plays it back much be able to recognize those non destructive adjustments and apply them on the fly. Sounds like devices such as an iPhone or iPad don't as they likely use the same basic QuickTime engine as QT X. Only QT 7 will play it back properly.

I just now did the same test in Yosemite. It's exactly the same. QT 7 will play back the video with the attributes. QuickTime Player in the Applications folder will not.

Perhaps you didn't understand me. I don't open those videos on an iPhone. Videos were shot on various iPhones but I'm trying to play them in QT 7 on my MBP. QT 7 worked fine in 10.10. It doesn't function properly in 10.11.

Yes, sorry, misread that part.

Regardless, something isn't working correctly on your Mac. I'm having no trouble with it here, so El Capitan itself is not the problem. At least not with a .mov file I have saved from another source that I used for testing.

I'll try shooting some simple video test with my iPad and see if it has the same issue under El Capitan as you do with video shot on your iPhone.

Edit: Okay, same result. Using a quick little video I just shot on my iPad 3 under iOS 9.0.2, any changes made with QT 7 display and play back fine under El Capitan. The QuickTime Player ignores the attributes.

I have another problem also, in el Capitan, Qt7 struggling the timeline doesn't show the progress in the player, just if I use the scroll from trackpad or mouse, but not "moving the dark grey minitriangle" from the timeline..

😠

Edit: Quicktime X it's a joke, so much power sleeping inside, why the h**l don't they merged them? quicktime X and a real Quicktime X Pro with the timeline OUTSIDE the player please... the Mac is not Youtube, we are not here just to watch cats.

I have also found that with El Capitan Panoramic mode no longer works either. Whereas before Qt7 stretched only the sides of the screen (leaving the centre area unstretched and in proportion) it now simply stretches the whole movie to fill the screen, regardless of its dimensions. I've found this really annoying.

Under El Capitan it seems like QuickTime 7 can no longer "Preserve aspect ratio by 'crop'" Has anyone else noticed that this doesn't work anymore?

It's working perfectly fine for me. Not meaning to be insulting, but you do have to select the Video Track, first. Sample shown next is a test video before applying any changes.

Note that Preserve Aspect Ratio is on. If I enter any value into either the height or width, the video scales proportionately:

If I turn the check box off, the expected result happens. It scales in one direction only:

Kurt, I agree Quicktime 7 seems to work on El Capitan but have you noticed the "Content Guide" is not drawn correctly?

Yes, I turned mine off. 😎

That I don't even know how to test for. 🙂

I purchased a key for QT 7 Pro a long time ago for something I needed to edit. Sometime after that, I was using Final Cut Studio, which automatically activates the Pro functions even if you don't have a key. Sometime again after that, I dumped FCS, went with the Adobe Premiere Pro suite and have never looked back.

That is, I do all video editing in Premiere Pro. I can't recall the last time I used QT7 to edit anything. Well, except for the video I happened to use for this example. It was much longer than I needed, so I trimmed it down to just the part that applied to my printer.

Just open the preferences, enable "Show Content Guide Automatically" then restart QuickTime 7.
