i just had contact with support regarding super slow rendering times – they referred me here.
i convert an h264 to a cropped png sequence, no effects applied (except the cropping).
if i do this in premiere or ae, it takes at least 2 hours and only utilises a fraction of my cpu. if i do the very same operation via ffmpeg (cli), it's done in less then 7 minutes. attached you'll find screenshots of the two procedures, note the render times (as said, same task, same machine, same result).

is this expected behaviour (because cc simply does not work on more then one core/thread) or a bug (and something can be done about it)?

system: macbook pro 15" mid 2014, macos 10.14.6, geforce gt 750m 2 gb, 16 gb ram, adobe cc 2020.

I'm honestly still surprised that even the latest versions of Premiere Pro CC still doesn't have this feature, Premiere Pro CC really at some point needs to add a Fullscreen Button both in your Computer's Drop Down File Menu and in the Program Monitor so you can actually playback all of your assembled video and audio clips in Fullscreen mode, and then obviously press "Esc" to exit out of Fullscreen mode.

I'm aware that you can use the ~ (Tilda) Key to closely zoom in and maximize the length of each window in each tab which I have used, but I want to be able to do a close analysis of assembled video by watching a Fullscreen video preview to do so.

I honestly thought the Premiere Pro Development Team would of added Fullscreen mode in future versions of Premiere Pro years ago, but now it's 2020 and Final Cut Pro 7, 10 and tons of video editing software have had Fullscreen mode for years, so I still don't understand why the team still never thought of adding a Fullscreen button if it was just an oversight by them.

To me this seems like a no-brainer. I hope that fullscreen mode gets added soon at some point in an update because this is such a basic feature that really should of been added years ago because it'll be very helpful to closely analyze a preview of your assembled footage before you export it.

Hey there, I've been plagued with endless slow load times, miserably slow saves (taking up to 15 minutes just to save a project), and memory spikes using this software. That I pay for. I'm working on a TV show and don't have the time or patience to deal with Adobe's lack of effort here. There are updates to this software that come up more than once a month sometimes and yet severe bugs and serious media management issues are yet unresolved. 50% of the time I have a second, tiny project open and want to close it, keeping my second project open, it crashes. Or locks up for minutes at a time, sometimes over an hour. Just to close a project! Not to mention, when I quit Premiere it just lingers for an absurd amount of time. I always force quit at this point because I can't wait around while a lazily built software tries to close down. What is happening here? Why aren't these issues resolved? Can I get a few more months free for the hours of time you wasted?

Big issue: Clip markers make project files huge. This is true from 2019 - 2020, and maybe before that. If your project file is huge, try removing all clip markers, particularly from wav and mp4 files, and watch your project file go from 50MB to 1.3MB. This causes Premiere to run slow, save slow, and open slow. I can't even permenantly get rid of the clip markers! I keep removing them, saving, exporting a sequence as a project, but they come back! FIX THE CLIP MARKER ISSUE!!!!

Big issue 2: Sharing sequences and bins. Good lord. Something Avid has down, but you guys can't seem to figure out. I have thousands of project files at this point that I can't even keep in one Project because to gets too big and won't work. Not an issue on Avid MC. Something like sharing a bin or sequence should be instantaneous, not require dynamic linking to another project and painstakingly importing a sequence from it which always takes way too long even if the file is small. How is using thousands of project files efficient? Obviously you guys thought this through that editors and other users would be working with others and sharing work back and forth, right? I see you have shared projects now. Gee, thanks. It's a separate subscription. Why is it not included in CC? Don't you owe us a shared option after dragging us through all this media management nonsense? Why would anyone pay for something that other editing softwares do by default? We're not even getting our money's worth with Premiere Pro as it is. No one seems to give a darn about it.

Your support team via chat is laughable. I've had to solve 100% of my issues on my own. They don't know the software and don't edit. Just routine cleanup procedures. I had a support agent suggest I had too many sequences in my project. Well, you can't have too many sequences in Media Composer. Why is it a problem here? Too many sequences?!? It's a TV show! TV shows movies etc require a lot of media and sequences to stay organized and complete a product. I can't be keeping track of 100 ****** project files when everything I need should be in one place. They also said a 100MB project file isn't big. I'm sorry....what?! That makes it clear these aren't active users, so what help is support if they don't understand at the edit level? A huge 100MB project will take an eternity to load and save. Again, this stems mainly from Clip Markers. Fix it. Please.

And, a support agent told me that the latest version of Premiere 2020, I forget which version exaclty, was not working properly and would be fixed in the next update (May). Why, oh why, was a new version released without testing every single aspect of the software. Why would you release that? Is it becuase of the subscription stranglehold you have on us, as long as we pay month to month you don't care? There are plenty of sorftwares that function properly out there. Please remind my why Premiere was my favorite. In a lot of ways it is. But these constant crippling issues make it difficult to stay on board.

FIX THE CLIP MARKERS ISSUE!

I find it really hard to still work on your software lately. I have a feeling that you don't test your updates before release. Mark my words, if you won't work on your stability, you will lose a lot of clients, especially now, during the pandemic, where people really work mostly at edits. I'm strongly considering going back to AVID right now.

In early 2020 you released some updates, that seriously broke my workflow. Especially with playback, that started laggin', and crushing, and doing really crazy stuff. It was somehow still possible to work, so I just tolerated it for a month, waiting for new fixes.

3 days ago, you released another update, that crashed my project down completely. Media pendente is the only thing I can see. I can't even import my sequences to 13.1.5 because it's too old. Im fuc***d.

I'm really sorry to say, but your software is amateur stuff and won't ever be considered pro, if you won't work on stability. You must test updates BEFORE, not AFTER. We update our soft, because we are full of hope, that it will repair some issues we were having, and instead of that, it gets worse, and worse, every time. Personally, I'm sick of this.

I've got pretty strong mac, not its fault. I edited far more heavier projects on it, than now. It's 100% your fault, and we expect some fixes, right now. If there wont be any, we just leave you and your playground alone. There ARE better software choices on the market right now.

Still believin' in you, but not for long.
