Bug Report: Findings on memory overload / crash problem
Here are some of my recent findings on this common issue, which has been described by various users in this thread: https://forums.adobe.com/thread/2562174
I have recently conducted a large series of tests to try and investigate this problem. For the sake of consistency, my tests have consisted of continuous playback of a sequence until either the crash occurs or the playback is finished. Each test was conducted in a new blank project. Each sequence has consisted of only a single footage file, always 4k Mp4 files, whose only dissimilarities ought to be the variation in file size. The files which I have tested have all been used by my colleagues without issue. The sequence settings have been kept constant, again identical to the settings used by my colleagues without issue.
Firstly, I found that on my computer, the crashes usually but not always follow a common pattern:
- For every file which causes a crash, there is a given range of uninterrupted playback time before the crash occurs, so the crash will usually occur after roughly the same length of playback. This is true even if playback is started at a different point on the timeline, or if part of the footage is cut out and playback is started from the new start point. For each file, it is unusual for any crash to occur more than a minute before or after the usual crash point.
- The crash will begin with the CPU usage and the usage of the disk on which the footage is located fluctuating erratically for a few seconds. At this point, playback will freeze.
- Disk usage will suddenly spike to 90 - 100%.
- Memory usage will begin to steadily and constantly climb from a baseline of 40 - 60% to 100%. Premiere will freeze, will not recover after any length of time, and will have to be forcibly shut down. Sometimes, the system itself will have to be forcibly shut down and restarted.
Secondly, I have found that the size of the files appears to contribute to the problem: the smallest file I have tested (10GB) seems to consistently not cause crashes, while larger files (15 and 20GB) consistently cause crashes. The size of the files ought to be the only difference between the files I have tested, as the codec, aspect ratio and acquisition method for all of the files is identical.

I'm having a very similar memory issue.
If I adjust length of the audio or the video clip, memory usage will climb to 100%. If I keep changing the length, Premiere crashes.
Here is a short video of the crash.
- Test clip length: 1:25
- 4k, MP4
Minor color adjustments and Warp image stabilization.
