[Update: RC4 is now the final release.] Here's to Flowframes 1.41.0 [RC4].
Added 2025-08-22 15:59:54 +0000 UTCUpdate: 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 now fixed this, and also updated certain plugins and libaries. The implementation should now no longer error. If it still does, tell me and DM me log files.
I replaced the cloud install files, which means you can also use an older 1.41.0 installer to install this update in case you still have one.

Installer fails to download files from both servers, not a good start

2026-01-28 18:37:47 +0000 UTCThere is no GPU selection option for interpolation AI. It only uses Vulkan-based backends (RIFE NCNN/VS, RIFE NCNN, DAIN NCNN). GPU acceleration is automatic via Vulkan

2026-01-28 04:36:50 +0000 UTCSo i used to be able to do custom frame rate conversions on 1.40.0 but now it no longer works, i got the latest 1.41 and it still wont let me. Just trying to convert 24fps to 30fps. Under output FPS i used to select the 2x and just type in something like 1.249 and it worked great but now it forces me into 2x at minimum, what changed? Help!

2025-12-03 16:12:47 +0000 UTCEverytime I try installing I get an error saying "Something went wrong" Before that happened I was seeing (Download failed: The underlying connection was closed: could not establish trust relationship for the SLL/TLS)

2025-12-01 22:57:52 +0000 UTCPreviously, with version 1.40, I could interpolate 4K videos with my RTX 4070 with 12 GB of memory, but now it's impossible. I get the following error: Vulkan ran out of memory! [E] vkAllocateMemory failed -2 Try a lower resolution (Settings / Max Video Size). :(

2025-11-30 12:01:41 +0000 UTCAlso why does version 1.40 have so many more models selectable. 1.41.0 [RC4] only have 3 models in the pull down menu.

2025-11-16 08:20:25 +0000 UTCNCNN has more features and should run fast enough

2025-11-09 14:09:12 +0000 UTCthanks to nvidia we got a new card with cuda without the tools to use it it is pain. most software has problems with it i hope it get fixed.

2025-11-08 15:09:57 +0000 UTCWhy is CUDA support removed? GPU usage is only 8% on my RTX 5090

2025-11-05 17:36:49 +0000 UTCHi, should I enable frame de-duplication mode when I use the experimental 1x frame interpolation mode introduced in 1.41.0 RC2? EDIT: Hmm, seems like the application will simply export the original file when disabled the frame de-duplication mode. However, I am getting audio stream faster than video stream weirdness (almost 0.5 seconds). FlowFrame decided to drop 30% of the video frames tho, I wonder if this is an coincidence

2025-10-22 20:40:42 +0000 UTCNo CUDA models?! I tried 1.40.0 but the CUDA models don't work they just get stuck!

2025-10-03 22:16:54 +0000 UTChello, thanks for the work ! I tested it today, and noticed while using the using the batch mode, I see that reordering jobs does not work : it does not start by the #1 .
Fredo
2025-09-29 20:06:42 +0000 UTCThank you for your perseverance and for all the time and headaches you endured. This program is still my go to for anything I want to interpolate. Topaz and winx be damned.

2025-09-18 02:16:47 +0000 UTCDoes this version support the use of tensor cores on nvidia cards? I don't see the option to enable it if so

2025-09-09 09:16:54 +0000 UTCdoes 4.26 do better than all the other models?

2025-08-23 04:37:57 +0000 UTCawww, that's what happens when you're a one man show. no one to look over your shoulder and say waitaminnit! :( good catch! :)

2025-08-23 01:23:45 +0000 UTCThis version has fixed the problems I have been having with every previous 1.41.0 RC!! Thanks for the update!

2025-08-22 17:53:55 +0000 UTCAhh that does explain the multiple irratic errors and crashes that kept happening. Thanks for the update, Ill test it tomorrow :)
