Premiere Pro CS6 crashes when importing 4K H264 MP4 Video
Hello,
I try to edit a 4K Timelapse-Video i rendered with After Effects in Premiere Pro.
The 4K Video has H264 MP4 as codec and runs completly fine with QuickTime on the Mac.Premiere imports the video and then it crashes.
It says, that there was a Problem with Premiere and that it has to close but tries to save the project.
I already worked with the 4K file completly fine in Premiere Pro, but like the New Projects i create, the old project with the video crashes when i try to work with it, but because i want to start a New project i don’t
care about the Old One, but just for information, the old One crashes now too !Everything except this 4K-Video-thing works fine in Premiere and the other creative cloud Apps…
Does anybody have any tipps/ ideas for me or is this a known bug ?? ( i couldn’t find anything in the Web…)
Things i tried :
-Re-installing Premiere ( with deleting the presets of premiere pro)
– different sequence settings ( but i think that isn’t the Problem because i had Premiere already running with them)
– deleting all caches (Media Cache,…) of premiere
-recoding the Video with adobe Media encoder to h264 MP4
-creating New projects and importing the videoI dont know what it could be, i dont have anything in mind that i changed that could cause this…
I edit on an 2011 i5 iMac with 16 RAM and an external Hard Drive for my Media.
Sincerely

What about encoding the timelapse video to a more edit friendly codec, like ProRes or DNxHD?
h.264 is a “great” delivery codec, but awful editing codec. Granted, Premiere Pro can handle (usually) h.264 files without much problem, but it is extremely hardware intensive.

I encoded it to ProRes, but i still have the same problem…
But in After Effects i can work with it and have no problems…

Another thing to say is, that everything works fine in Premiere, that isn´t larger than 1080p, no matter which codec.
I scaled the 4k file down to 1080p and it worked fine, but i want the full resolution not the cropped one !

Right now your workflow doesn’t make sense in my mind. We’ve got a 5.5k display at work (it’s an odd shape) and for editing I’d use 1080 ProRes/DNxHD before 4k H.264. Sure the H.264 will have a bit more resolution, but it’s missing subtle colour gradients and it’s going to pop at every keyframe. Just because Premiere will take H.264 natively doesn’t mean you need to use H.264. There are several formats that are more appropriate.
Second, I suspect you have a hard on for 4k without good reason. The fact that you’re exporting 4k to H.264 tells me this. If you want to retain detail H.264 is a terrible choice. It’s an 8 bit codec, so subtle color tones get banded. The sky may be a few shades of blue instead of a smooth gradient from light blue to dark blue. The Long GOP structure might make the blue in the sky pop every second. So one frame in 30ish your timelapse will have all the detail possible, then as you scale up things will get more mushy until another keyframe, at which point it will pop with detail, then begin to smear as the image scales in further.
If your finishing resolution is 4k then preserving 4k makes sense — provided you’re using an editing codec.
If you’re finishing in HD and you’re having trouble with 4k there’s a better approach — working with HD in an editing codec.My suggestion?
How about you use AE to make the footage look the way you want. By that I mean create your timelapse, add scaling, time remaps, etc. with the high res media. Remember precomposing will probably be your friend. Precompose all of the clips, then do your scale, perspective, and time effects to the precomp. Export your precomp (at your finishing resolution, 720/1080/4k) into an editing friendly codec, then bring that into Premiere. All the scaling was completed with the high res media, so as long as you don’t scale it in Premiere you’ve retained more detail than a 4k H.264 clip would offer, and you’ve minimized complexity.
The editing codec I suggest would be DNxHD on either platform, or plain ProRes422 would be fine on a Mac, though the ProRes engine in Premiere is 32 bit.a===
If you’re adamant about bringing 4k into Premiere and you don’t want to use an editing codec, perhaps you should take advantage of the dynamic link and bring your AE project into PR? Doing this avoids the H.264 intermediate.

I normally encode my timelapses in After Effects, Then i import these timelapses into Premiere and Cut Them together.
And yes now i know that h264 is a Bad codec for my 4K Videos, but i already rendered Them in H264, next Time i will try in ProRes…
BUT !
That isn’t my Problem !
Premiere does Not accept any 4K file !
I tried different codecs like H264, ProRes and some 4K Videos from the web, everything crashed, also when importing a 4K composition from After Effects vie Dynamic link, already tried that….
This is so annoying and i dont know what to do…

Well, I did offer a couple of suggestions. Are you finishing in HD or in 4k?
• If you’re finishing in HD export an HD video (ProRes/DNxHD) out of AE. Do your animation in After Effects. Remember precomps — they’re your friend.
• If you’re finishing in 4k import your AE comp into Premiere. Again, do your animation in After Effects using precomps. -
I Finish in 4K.
And how i said
Importing 4K Videos or comps into Premiere doesn’t work, which is my Problem !
So
” If you’re finishing in 4k import your AE comp into Premiere. Again, do your animation in After Effects using precomps.”This doesn’t work !

Do you have 4k media on your timeline already?
-
No, it also happens when i start a complete New project.
-
Have you done 4k before?
Do your previous 4k projects open up?
