Choppy video after exporting.

A lot has to do with the fat that H.264/5 is great for shooting compressed video but absolutely sucks for editing. A new codec is needed or something and no mixed timelines do not work with DJI footage unless 3./60 sort of thing and Proxies no better regardless of what youtube screamers say.Maybe AI can figure something out and I dont have to be an alchemist. AND NO FULLY DECKED OUT M4 MAC MINI CANNOT HANDLE UNCOMPRESSED DJI 4K FOOTAGE ONCE YOU PUT ANYTHING ON IT LIKE A COLOR EFFECT OR MOTION EFFECT,.

Exporting h265 (HEVC) through media encoder fixed the frozen render issue for me (which was happening for drone clips and also any 120 fps clips)

Instead of clicking export on the bottom right, click Send to Media Encoder.  Then on the media encoder click the green arrow.

I tried everything and honestly... it was just the default Media Player in windows for me that played it choppy. I ended up "opening with" and selected "Movies and TV" and all the renders that played choppy played completely fine.

I have alomst certainly found the issue. I just went through this today for a few hrs. I also read this thread 3 times.. lol here it is..

I was working on an already exported video adding some blur to an area for a client. The video was choppy, and struggled to play in premier. It also wouldnt play back smooth in quick time. After some digging I realized the dimensions were too high. I had exported the video at H.264 8064x4536. The M1 Max Mac Studio im on just doesnt want that kind of resolution. All other videos and raw files I checked are in 4k H.264 3840x2160, and play smooth. I figured it was a computer issue when I uploaded the larger dimension video to Youtube, and it played fine. So yeah, Check your export settings. Even if you are in H.264, Adobe will push the dimensions if you dont force it to export in a 4k aspect ratio. You just have to unceck a box in the export window under "video" "basic video settings" and "frame size" Make sure it is UHD 3840x2160. otherwise it will be choppy unless you have an 8k monitor, and a beastly beast of a comp. Hope this helps you, and others. I almost lost my mind finding this solution.. Cheers, 

Hi Don't waste your time with any of the solutions you read to this problem on any of the message boards including this one. I get all the choppy playback upon export of my DJI Air 2S footage from Premiere Pro as described here and elsewhere and I have super fast SSD drives and no frame mismatches. I draged the footage on the sequence and let PP set it up. I supect it has to do with H.264 and H.265 being crappy codecs more "sumer" than'pro". When I export my 4K  same as source or any other codec of my DJI Air 2S footage it plays like crap on my brand new Mac Studio however when I bring the sequence back into Premiere Pro it plays beautifully. Maybe Quicktime player needs and over haul. When I take that same sequence exported with the Vimeo 4K quicktime preset into Vimeo it plays it more or less  OK. Here's a fun fact. If import the same sequence that played choppily in Quicktime on my desktop back into PP it plays fine. If I had to guess it is an H.264 problem and I am not going to waste my time with alchemy trying to get out a decent looking video. DJI, Adobe and Apple get together and fix this so as not to drive your customers crazy. Much love to all.  This isnot your fault your tech overlords need to fix this. Maybe immediately transcode your video to pro res for editing who knows just please fix it. Who knows I am tired of trying to fix this.

Is the timeline video 8 bit and the render video 10 bit? 

Hi Elle,

Try exporting a HD version and see if you have the same trouble.

Thanks,
