Question

Premiere Pro keeps crashing on export for iPhone 6S MOV files

I've never had this issue before with 4K MP4 files.

For the first time, I tried putting together a series of MOV clips recorded with my iPhone 6S. The video quality is lousy, so I thought exporting would be a breeze.

At first, the export kept freezing at 41%. So I tried copying the entire sequence and pasting it to a new timeline. When I did so, I got up to 46%, but alas, it froze again.

I tried exporting Media Encoder, but it froze even faster, like around 11%.

Finally, I tried exporting the video with zero effects on Media Encoder. It's just a series of MOV files strung together. I did this with the hope that I can add effects to it later with the resulting MP4 file. Sadly, it froze on the second pass. The clip that it froze on is just a simple MOV clip with no effects.

I have no idea why this is happening. The video is 25 minutes long. I'm starting to feel like I've exhausted all my options.

My last ditch effort will be breaking up the video into multiple parts, like exporting 5 minutes at a time, and then perhaps piecing it all together.

iPhone is a pretty popular phone, so I'm surprised Premiere Pro is crashing trying to export MOV files. But for whatever reason, this seems to be a fairly isolated problem, because I tried searching for similar problems on Google to no avail.

I'd appreciate any suggestions. Thanks.

UPDATE: I tried exporting just the first 5 minutes, and it froze at 84%. I then tried exporting the remaining video to see if the glitch was occurring in the first 5 minutes, but at about 15%, the program just closed on its own. I do not understand why this is happening. I have plenty of storage (3+ TB), BTW, so this isn't a storage issue.

    Totally... I recently built my PC for the first time, and I studied tons of videos on overclocking to make sure I did everything right. Eventually, I relied on the maker of my PC motherboard; they have a video with their tech guy walking you through each step.

    Even still, my CPU seems unstable for whatever gain it achieved. I got caught up in the overclocking culture, but ultimately, I don't consider myself a PC building hobbyist, and I don't want to be sinking so much time troubleshooting. I prefer to set it and forget it, even if it means setting the PC at stock settings.

    I suspect that my fail safe setting is set too low (line level or the voltage). The CPU is disengaging and freezing up because it thinks it's about to burn out, even when the temperatures are still well within normal limits. But I've spent way more time on this matter than I prefer, and I surrender; for me, it's not worth the trouble.

    I'd rather a video takes 10-20% longer to encode, rather than freeze up and give me fits.

    Thanks a lot again, Neil, for sharing your experience and expertise.

      I'd go with transcoding the iPhone original clips (which are H264 or HEVC) to a CODEC that's good for video editing like Apple ProRes 422 (LT) or GoPro Cineform 3.  They'll take up more drive space than their originals, but well worth the benefit you gain (higher color sampling, better peak signal noise ratio, intra-frame compression, Smart Rendering when exporting from Premiere Pro, etc.).

        Actually, I just tried highlighting all the files with "SHIFT" button in the bin, and Premiere Pro astonishingly allowed me to Modify/Interpret to 59.94. Very surprised, because PP is usually very limited with mass editing abilities. Okay, I guess I'll try this method out for now, since it appears to be the method of least resistance.

        If this manual version works, are there any drawbacks vs the Handbrake method?

        Also, if I use the Handbrake method, should I use your settings instead of the one provided by default? Thanks a lot so far!

        UPDATE: I tried mass editing with the settings you suggested, but the export still failed.

        UPDATE 2: I tried converting MOV to MP4 through Handbrake, but I can't get the videos to link up. It seems Premiere Pro is locked into the MOV codec.

        In the re-linking process, there's an option box to use or ignore the file name extension. Un-check that.

        Alright, so after a lot of trial and error, I found out the root of my problem. I tried everything. I even followed your instructions to replace all MOV to MP4 files, and still, the program froze. For whatever reason, it had to do with the overclocking on my computer. I just went into my BIOS (clicking F2 or DEL at the boot up of computer) and then I just clicked on the button to get back to "Optimized Default" settings. And now my computer is a bit slower, but after running multiple tests, it's not only having zero issues encoding the MP4 version of the project, but it's also encoding the MOV version with zero hiccups as well!

        So if anyone else is having trouble with Premiere Pro freezing up, this is something to consider! It's a lot easier to reset your settings, than jumping through hoops like I did.

        Thanks a lot for all the help, Neil!

        I think I'll try out the Handbrake method, because unless there's a way to mass edit a batch of files to "59.94," individually changing each file seems more time consuming and labor intensive.

        Should I change any settings in the Handbrake interface? 

        Unlike the example snapshot you provided above, the default setting for my Encoder Profile is set to Main, and Encoder Level is set to 4.0. Constant Quality is also set to 22.

        I like to maintain quality and avoid decompressing to an even smaller file. Ergo my settings. They should maintain file size at very close to original quality.

        At home on my phone at the moment and I can't remember, can you select multiple clips on a sequence and modify/interpret time.

        First thing is that Premiere is better with VFR (variable frame rate media) but not perfect.

        I would suggest going into the bin and selecting all the clips, Modify/Interpret and set a  frame-rate for them. The move some to a new sequence and see if that test sequence can export.

        If it does ... fine. If not ... download Handbrake, and use that app to quickly convert this media to CFR (constant frame rate) which should then work in Premiere fine.

          Thanks for answering. I'm a little confused. When I go to "Modify/Interpret Frame Rate," there's a blue check for "Use Frame Rate from File: 59.9401"

          Do you want me to uncheck it?

          The option beneath it reads "Assume this Frame Rate: 1.00 fps"

          What frame rate should I set it to?

          Also, if I use Handbrake, wouldn't I have to re-import the new files and re-edit the whole project?

          Try setting it to 59.94, dropping the "01". Which is the type of thing you get in a VFR frame rate. Or "30.04" ... numbers that don't come attached to any actual video camera.

          If you use Handbrake, and export as a batch the same names for the files, then ... no, you wouldn't have to re-edit.

          With Pr closed, change the name of the folder the originals in by some small thing, like adding a 1 before the name or something. Have the replacement folders in a sub-folder alongside the folder the originals are in.

          Then open Pr, right-click on one of those files that now should have a question mark, use the Link Media... navigate to the new folder of media, and select the first clip, then click "Locate". Then find the file in the new folder, "Ok" ... and it should replace the group.
