Hello Forum Users!
I hope you can help me...
I'm currently in the process of editing a large project in Premeire Pro consisting of 16 videos ranging from 8 - 12 minutes each. I'm editing on my Macbook Pro 2015 (15 inch) — 16 gb memory and Intel Iris Pro 1536 MB graphics card.
However, I've been experiencing a very annoying export issue in both Pr and AME, in which all of my exports within a specific project, are out of sync by at least 5 frames — I know this through dropping the exported video back underneath the video in my timeline, and from it being quite noticeable to me. But this isn't a gradual issue, in which the audio slowly falls out of sync over time, it's consistent throughout the videos from start to finish.
The project contains a mixture of 4K and 1080p footage all shot at 29.97 fps, but neither of the sequences contain mixed resolutions, it's either all 4K or all 1080p — I have attached screenshots of my sequence settings (4K and 1080 timelines). What I have also noticed (and I'm not sure if this makes any difference) but my "Source Audio Format" is: "96000 Hz - 24 bit - Stereo" and I'm limited to exporting a sample rate of 48,000 Hz with the codec and presets I'm using (H.264, 1080 x 1920 using both Youtube and Vimeo presets). I also believe the interviews were shot on a Sony A7S iii. In terms of effects, I have applied Lumetri grades to all of the interview footage, as well as the Cosmo effect from "Magic Bullet". I've also used the Dynamic Link feature with After Effects, to add some rather simple text and line animations which are consistent throughout the edits.
Insofar, I've tried changing my settings in AME to Mercury Playback (Software Only), which was successful in removing some really strange glitch issues in my exports. I've also got onto Adobe Support, using their live chat system, where I was recommenced to try "HANDBRAKE", again this yielded slightly better results, but this ins't an ideal fix as I have a lot of these videos to export, which range from 7 - 12 mins each and just need them to be exporting out from AME overnight!
I'm just lost to what to do, it's for a client of mine and I just feel I'm falling at the last hurdle here...
Any recommendations on a fix would be amazing! Sorry if I've missed any important information — it's my first time posting on here.
Thanks in advance!
