Theeere it is.
This one got way bigger than planned but I'm finally done with 1.42 (I think lol).
Here's an overview of the biggest features, fixes and changes.
New: Support for HDR video interpolation (bt.2020)
New: Support for Al...
2026-01-29 21:59:58 +0000 UTC View PostYeah, I said it'd be ready "in a few days" which was almost a month ago.
Buuut, I did actually make some notable progress in that time (also christmas was a thing).
Here's some important things that I noticed just when I was about to wrap things up, with most of them actually resulting i...
2026-01-12 19:28:50 +0000 UTC View PostSo... it's been a while, again, and I'm sorry for that - lots of IRL things happening, plus my ADHD makes it very tempting to work new projects all the time, but I'm doing my best not to abandon major ones like Flowframes.
I've gained a lot of programming experience, both from my office job...
2025-12-11 23:24:21 +0000 UTC View PostUpdate: Release Candidate 4 is now the final release (Flowframes 1.41).
I noticed that I made some changes to RIFE NCNN VS in my development environment without copying the changes back to the repository, which caused the script to break in many scenarios.
I...
2025-08-22 15:59:54 +0000 UTC View PostThird time's the charm...
With a bit of luck, the final release candidate.
I'm really sorry that I kept you waiting for so long, I got distracted by a lot of stuff going on IRL and neglected this project for a few weeks.
That said, I hope I'm back on track now, and here's th...
2025-07-20 17:17:26 +0000 UTC View PostFixed:
- Custom output folder option was ignored
- Legacy deduplication dropdown was shown when deduplication is set to Disabled
Improved:
- Resolution modulo is now determined via pixel color format instead of encoder. This means that H264 or ProRes are no longer forced to a reso...
Since RC1 did have some rather critical bugs/oversights, here's the next release candidate for 1.41.0.
Changes since RC1:
- Fixed batch processing queue not working properly
- It is no longer possible to add invalid (e.g. no path) GUI tasks to the queue
- Fixed mu...
Sooo, I'll make this quick since I promised myself to release something before the year is over and I have less than 40 minutes left for that in my time zone.
First of all, sorry for the insane delay and the radio silence.
A lot has changed in my personal life, which made things more ...
2024-12-31 22:40:17 +0000 UTC View PostSo once again, sorry for the massive delay as I was distracted by Stable Diffusion and other stuff.
Anyway - Here's, finally, a new Flowframes version.
It adds the latest RIFE 4.6 model to all implementations (NCNN/VS/CUDA), fixes some important bugs and UX issues.
The output fo...
2023-02-23 11:11:57 +0000 UTC View PostHey everyone,
first of all, I'm sorry for the radio silence and the lack of Flowframes support in the recent months.
I started working on my Stable Diffusion GUI in September and ever since it kept me super busy, causing me to neglet my other projects.
I can ensure you that in t...
2022-12-24 15:36:49 +0000 UTC View PostThis update adds real-time interpolation (currently without audio though), you can select it as an Output Mode.
Also, RIFE 4.4 and 4.3 have been added to both RIFE NCNN and RIFE CUDA.
Full changelog on Discord 2022-09-14 08:24:49 +0000 UTC View Post
Even more fixes, and some additions.
Slowmo feature now works with RIFE-NCNN-VS, using image sequences as input now works again (and has a nicer workflow where you're prompted to enter a frame rate to use), RIFE 2.3 has been added to the RIFE-NCNN-VS models (only supports 2x though) for tho...
2022-08-04 20:40:58 +0000 UTC View PostMore fixes and improvements regarding RIFE-NCNN-VS.
FPS limiting now works (just like regular RIFE-NCNN), and users who previously got the error "gpu_thread must be between 1 and x" should no longer have any issues.
Full changelog on 2022-07-25 09:18:44 +0000 UTC View Post
This update primarily focuses on some things that were broken with the new VapourSynth implementation of RIFE (RIFE-NCNN-VS).
It now respects the GPU ID set in the settings (NCNN). However it currently can't do multi-GPU, so if you specified multiple IDs, it will only use the first one.
... 2022-07-21 08:42:17 +0000 UTC View PostSo here it is, the first Flowframes version with VapourSynth-based RIFE, eliminating the need to store all the frames on disk.
Do keep in mind that some things don't work with the new implementation yet, like FPS limiting/downsampling.
Full changelog on Discord and in Flowframes.
2022-07-05 22:37:21 +0000 UTC View PostFlowframes 1.38 is coming soon, and there will be a game-changing new addition: VapourSynth-RIFE-ncnn-Vulkan has been integrated (called RIFE-NCNN-VS in Flowframes). This means you c...
2022-07-04 09:07:39 +0000 UTC View Post
Fractional interpolation now works fine with RIFE-NCNN, both scene detection and deduplication have been fixed.
Also, the RIFE 4.1 model has been added to RIFE CUDA and NCNN however the NCNN version seems to be broken and causes flickering. Stick to 4.0 for now.
Full changelog on Disc...
2022-06-01 17:14:29 +0000 UTC View Post
So initially I wanted to fix deduplication and scene detection for fractional factors but it took a bit longer than expected, but that's not a big deal because I managed to add a bunch of other useful stuff in the meantime.
Custom interpolation are now enabled by default (instead of being a...
2022-05-04 15:16:56 +0000 UTC View PostSorry for the long wait - I've been rather busy with Nmkoder and some IRL stuff.
Anyway, here it is - Flowframes 1.37, now with RIFE 4.0 on NCNN (for AMD/Intel GPUs).
Not only has it been added to NCNN, but it's also a lot faster, making RIFE-NCNN roughly as fast as the CUDA version.<...
2022-04-17 18:23:20 +0000 UTC View Post
This update comes with the RIFE 4.0 model which improves quality over 3.9 while also being faster.
In addition, some bugs have been fixed.
Full changelog on Discord and in Flowframes.
2022-01-02 15:26:59 +0000 UTC View Post
RIFE has finally gotten another big update: It can now interpolate with any factor. It still has to be an integer (whole number) but apart from that you can now chose anything - 3x interpolation, 5x, 10x, whatever. It seems to get unstable at more than 16x but I don't think you'll need that anywa...
2021-12-01 19:34:23 +0000 UTC View Post
This update improves the slow-motion feature by changing the audio tempo to match the video speed. It also fixes some bugs and improves encoding efficiency for certain codecs.
Full changelog on Discord and in Flowframes.
2021-10-27 12:18:03 +0000 UTC View Post
This update adds something I actually wanted to add much earlier: Resuming unfinished encodes.
For now it requires auto-encode to be enabled. When an encode fails (or you manually cancel it) you can later drop the temp folder into Flowframes and it will resume, skipping the existing encoded...
2021-10-01 10:32:11 +0000 UTC View PostAnother update that was planned as a minor update but ended up getting slightly bigger.
This update adds quality/compression options for image sequence exports (and fixes WEBP using the lowest quality by default).
There is now a server selection in the settings (Auto/EU/US), previousl...
2021-09-13 16:08:25 +0000 UTC View Post
I originally planned to release a smaller 1.31.2 update, but I kinda kept adding new stuff and now it's easily big enough to be called 1.32.
This update adds a slow-motion option so you can easily make slowmo interpolations without having to adjust framerates or needing extra tools.
I...

This update fixes XVFI not working with embedded python runtime, and adds the missing checkbox to download XVFI in the models downloader.
2021-08-24 23:07:24 +0000 UTC View PostI ran into some unexpected problems with XVFI in combination with the embedded runtime. If you have the know-how you can use it with your own Python installation, otherwise wait a few days for my fix.
2021-08-24 19:30:26 +0000 UTC View PostSorry, I messed something up and the code for XVFI wasn't included in Flowframes 1.31.0.
If you need XVFI, please re-install 1.31.0, it should work now.
2021-08-24 17:58:26 +0000 UTC View Post
This update adds a new interpolation AI called XVFI - Read more about it here. It's sadly not faster than RIFE, but it allows for more interpolation factors like 3x or 5x.
But apart from this new AI, RIFE-CUDA and DAI...
2021-08-24 14:27:32 +0000 UTC View PostThis update adds some neat features - Most importantly, you can now set an action that will run after interpolation has finished. For example, closing the app or putting your PC to sleep.
