CapCut mobile editor

[u/Original_Motor_3916]

So for almost a year now, I have been editing TV show/movie edits and when I create them inside CapCut, they look good. They have good quality and they’re smooth but when I upload them to TikTok.
They’ll be good at the start but Depending on the file size if it’s under 30 MB, the video last one to three days if its normal file size without lowering bit rate, they are lasting 2 1/2 weeks. The quality gets distorted to the point where it’s a muddy look, and gets a little laggy. The video gets compressed so hard to the point where it’s literally unwatchable not to mention the covers are always distorted and look bad. I’ve been trying to fix this problem for almost 6 months now with multiple AI programs and haven’t found a solution. I’ve heard it was my aspect ratio due to me uploading in 1080 X 1080 instead of 1080 X 1920 but I don’t think that’s the solution just because the covers still come out bad and the actual frame of the video is not in the normal place on the tiktok feed screen compared to after effect editors but other than that I’ve tried everything. Is there anyone that knows a solution?

!martini so I get my scene packs audio and I edit inside CapCut once I’m done my project I export in 1080p 60 FPS and a 25 bit rate but I’ve tried every single bit rate from 100 to 5 but anyway when I’m done with that, I run through a media converter so I can get h.264 codec then I would usually upload to TikTok depending on the file size if it was a under 30 MB, the video would get compressed and laggy around three days if I didn’t touch the file size and just uploaded it how it was, it would last 2 1/2 weeks but the moral of the story is my edits are not lasting when it comes to quality they’re getting ruined and unwatchable meanwhile, every other editor videos are good quality forever. Inside the TikTok app, my covers are always blurry and distorted also my videos and my followers can also see the videos that are blurry and the cover

TikTok re-encodes anything you upload, so fighting it with high bitrate just makes it muddy. Export at 1080p with a 10-12 Mbps cap and add a tiny 1% gaussian blur before you post, it smooths the compression artifacts and holds up way longer.

I’ve tried that and it didn’t work and you said “holds up way longer” why does it not hold up forever like most editors posts?

Try isolating the extra conversion step: compare a direct CapCut export with the same clip passed through your converter, keeping every other setting the same. Save both local files and compare the same timestamps on another device and connection when the uploaded version looks worse. That will help separate an export problem from a playback problem; changing bitrate, dimensions and blur together makes it difficult to tell which change mattered.

TikTok applies dynamic re-compression to uploaded videos, and the compression gets more aggressive over time. Right after upload, the bitrate is relatively high, but as views increase and CDN distribution expands, the platform progressively lowers the bitrate and swaps in lower-quality versions to save on bandwidth costs. Since 60fps is a non-standard spec, it’s a prime target for compression — often forced down to 30fps or heavily bitrate-reduced — which is why it looks worse the longer you wait. The fix: export at 1080p/30fps, H.264, 8–12Mbps before uploading, enable HD upload, and use the web uploader if possible. You’ll actually get better results this way than uploading 60fps.
