So 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 format selection has been completely remade, replacing the entire settings tab. Instead, you can now pick the output container, codec, quality and color format independently, without needing to open the settings.

Image sequence output now also works with RIFE-NCNN-VS.

Some bugs with the queue have been fixed - For example, when queueing up image sequences, you are now prompted to set their frame rate the moment you add them - Not during queue processing which would make the batch processing feature pointless.

RIFE-NCNN-VS no longer shows an error if you try to interpolate inputs that have a resolution that's not divisible by 2 (can happen with GIFs or frames), instead it automatically adds padding.


Full changelog on Discord and in Flowframes.

Thanks! There is only one issue with this version: The NVENC (H.265) HEVC encoder is not working anymore on GTX1060. With version 1.39 the NVENC H.265 encoder is working without problems. I can still use H.264 encoder but I would like to use the H.265 NVENC encoder just as before. Can you please fix it? Thanks in advance!

According to the error message it's related to B-Frame support. This version (1.40) requires B-Frame support for HEVC encode, but Pascal encoder does not support it. The previous versions didn't have such requirement, they worked without B-Frame support. Your RTX 4090 has no issues because it has much better encoder with full B-Frame support in HEVC. Pascal architecture has B-Frame support only in H.264. So the problem is that somehow this latest 1.40 version made B-Frame support under HEVC mandatory. Here is the original error message: "MessageBox: VapourSynth interpolation failed with an unknown error. Check the log for details: [E] pad:default -> Stream #0:0 (hevc_nvenc) [E] [hevc_nvenc @ 00000208b2ebe640] B frames as references are not supported [E] [hevc_nvenc @ 00000208b2ebe640] No capable devices found [E] Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height [E] Conversion failed! [E] Error: fwrite() call failed when writing frame: 3, plane: 0, errno: 32 (Error)" Version 1.39 works perfectly with H.265 NVENC because in version 1.39 B-Frames under H.265 were only optional and not mandatory, but I'm just guessing.

I also encountered a similar error when attempting to interpolate frames

Adrien Oneiga

Hi! i'm happy to see this, i'm not sure why, maybe it was an older version, but i noticed every 3-4 frames the frame would be out of order

Hi! I use Flowframes for both .gif and .mp4 formats. There is a colorshift when creating a gif as I know you're aware. The solution for me was to use "-pix_fmt yuv420p -vf scale=out_color_matrix=bt709 -colorspace bt709 -color_primaries bt709 -color_trc bt709" in the additional (Output) Arguments under Developer Options. This worked great in 1.39 but in 1.40 I'm getting this error when I try to interpolate a video. "[ffmpeg] -vf/-af/-filter and -filter_complex cannot be used together for the same stream. Canceled interpolation." I have to remove the output arguments every time I switch between gif and mp4. This didn't happen in 1.39. So far I've tested it using XVFI(CUDA) with the X4K1000FPS model and RIFE(CUDA) with the 4.6 model.

When using any Vulkan RIFE model, I keep getting this weird issue. Doesn't even interpolate anything and says waiting on encoding to finish, then gives me an error. This is with 4K footage. It seems to work n do better with 1080p tho. I have not tried the CUDA RIFE model. I just wanted to try the custom FPS of Vulkan. Screenshots of error below: https://ibb.co/FmSMNj7 https://ibb.co/jMy6sJv

Because both RIFE NCNN VS and the original freezes b4 doing anything as shown in those screenshots. It either says waiting on encoding to finish then produces that error shown, or it doesn't interpolate at all n jumps straight to tryna encode the file for some reason. Matter of fact, the only RIFE that works with my 4K videos is RIFE CUDA only. Both RIFE VS n regular work fine on all videos 1080p n below. They're just clearly having trouble doing anything for my 4K videos

Thanks for the hard work! Please check my DM regarding sponsorship :)

n00mkrad

I see, I will implement some checks in the next update to disable the unsupported features on older cards

This is why I don't use RIFE NCNN or RIFE NCNN VS at all in any version u released after 1.37 (the only one that never gives me issues with my 4K videos in ALL RIFE models). Either gives different errors when starting the process, or keeps checking the hard drive for space for HOURS before doing anything or right after 20-24 hours of interpolating (version 1.37 gets my 4K videos done in less than 10). RIFE CUDA is the only model that seems to work fine in all ur versions for me personally (still gets stuck at the checking hard drive for hours part tho). Here is the program checking for hard drive space way too long again. In version 1.37, this only takes SECONDS: https://ibb.co/tDpXdTL

GamingCanBeFun (YouTuber)

Here's yet another error that's now happening. This is with RIFE NCNN VS: https://ibb.co/g4k4yGC It's either both RIFE NCNN and VS gives errors no matter what I change, checks the hard drive for hours before or after encoding (too much time wasted) or takes 20-30 hours to interpolate any 4K video over 20 min (version 1.37 only took 10 or less per video). CUDA also takes hours to check the hard drive on all versions after 1.37. I give up, I'm going back to 1.37. All I have to do is copy n paste the new models from ur new releases into 1.37 n I'm golden (most of the time). I've tried all the new versions after and 1.37 is the only one that NEVER produces ANY problems. I'm sticking with that. I'll keep downloading ur newer updates to check if the "checking hard drive for hours" message gets fixed, encoding takes less time like 1.37 (20+ hours vs 10 or less. It's no contest), and it doesn't give any errors at all with 4K/8K input. I can do 4K 240fps and 360fps with both RIFE NCNN and RIFE CUDA in 1.37 no sweat... again, ty for ur hard work. Apologies if I sound frustrated. Ur program is way better than Topaz's. With some tweaking/fixing, it'd be perfect

Frame by Frame Figures

I got the same error. I tried version 39 and the new version 40 but so far, only the free version 36 on itch.io works well for me

SooksVI

I'm getting a ProRes Encoder error using RIFE CUDA

Max

No issues here, just a strange observation: When I used RIFE CUDA 4.6 on freshly rendered frames (.png) the interpolation produced rubish. Interpolating the same input, but already transcoded to H.265 the result became almost flawless.

Cloud

Anyone else getting an error trying to export to "frames" option?

Lucian K

hey, any suggestions for removing any artifacts when interpolating transparent 2d animations (I want to turn 10 frames into 30 frames for a video game project)? I tried many, many combinations of settings

PirateDiffusion.com

Awesome man thanks for your hard work, always!

Max

Topaz Video AI could do the trick after the Frames Interpolation with Artemis Model. You could do also frame and denoise at once with that tool, but frame interpolation of Flowframes is visibly better in most cases

Andersun

Hi! The Flowframes is really super! Thank you! Nevertheless after several successful using I've got a problem: Frame extraction failed! Your input file might be incompatible! What the reason could be?

armin otto

Easy to use, works like a charm. Er, where do I send bug reports? 😁

genericmarmoset

https://github.com/n00mkrad/flowframes/issues won't do much good. he's got 95 open tickets.

Petja Linnanen

These comments should be visible before throwing a buck to a creator. I've been using the free version for quite a while so I guess it's fine but definitely feels like I got bait'n'switched.

Al Omega

I was hoping I could get help here. I've used this for a while, great program, but I had to reload it and now it won't work.

Ciels SX

only the free version 36 on itch.io works well for me too

Erick Carvalho

Oh, no... the new output quality settings. I used to pick the CQ I wanted, and that was just fine!! Please, bring CQ back!!!

qeqeqeqeqeqe

my interpolation factor wont work sadly

Joshua Holmes

Hello, is there a guide on how to use the software?

FlashTutorDE

Error when use same settings as 1.37 same video.

Rejoined as I quit due to the massively long radio silence, but I'm glad to see Flowframes getting an update, let's hope this trend continues…

RIFE 4.6 gives me a broken .mp4 file

Jake Rawls

I've used the free version for so long I thought I would finally pay the fee to show my support. Very disappointed to discover this version is broken/errors out constantly and the developer has gone radio silent. I understand you're just one person and have multiple active projects, but right now I don't see any reason to pay the patreon fee in the coming months? I'm downgrading to the free version since that never caused any issues.

Sean Bannister

For anyone struggling with bugs installing and running 1.40. I received error saying it couldn't import skvideo.io and couldn't find avcodec-60.dll and other dlls but this will probably fix other issues. When you install it will ask "Select GPU Acceleration" select "Vulkan + CUDA (NCNN, Python Frameworks)" If you select auto detect you won't get the next install screen. where it asks "Select Python Installation To Use" select "Install Embedded Python runtime with all dependencies. If you need to export to ProRes note that some of the options are just broken. I know that the following works: Mov, ProRes, 444, YUV 4:4:4 10-bit.

Ata Uslu

Finally an update. resubscribed after seeing this. hope bugs will be fixed. can you check new engines for anime.

YUG

any chance to get mac version?

Valera Zadorin

why is there no preview window ?

dharak

i have upgrade my old gtx 1030TI to rtx 4070. hope its not take like an hour to upscale fpss

Endymion74

this version fixed all the bugs i had, before it stopped without reason. do you think you'll release a new version soon ?

End User

So glad i paid to upgrade to a version that's broken.. No module error is infuriating. rife-cuda-log.txt [00000478] [10-29-2023 07:32:41]: [E] Traceback (most recent call last): [00000479] [10-29-2023 07:32:41]: [E] File "rife.py", line 4, in [00000480] [10-29-2023 07:32:41]: [E] import cv2 [00000481] [10-29-2023 07:32:41]: [E] ModuleNotFoundError: No module named 'cv2'

Still can't output image sequences with this version, fix it please!!

echy

Hello, I recently downloaded the latest version and the product listed does not work correctly, When trying to import png and export it .. the image sequence turns out destroyed or it turn out super extremely slower not true to its original video.. instead of adding frames it like just makes it slow and choppy

SooksVI

How do I get this to work with ProRes HQ 422 10bit? I get VaporSyth Interpolation failed and "rife-ncnn-vulkan.exe has stopped working".

Is there a way to limit Flowframes so it doesn't use all the CPU's at the same time so I can do other work on my computer while processing a video?

malcolm341

Also, the output file is upside down? Is there a way to not have it flip during processing?

malcolm341

Caneling my subscription, doesn't seem to be any active development or replies to simple questions in a timely fashion.

Mark Emmanuel

Where is a new version? There has been RIFE 4.14 for 6 weeks now, which apparently looks amazing for animations

EvilMadness

I'm going to cancel my membership there hasn't been anything new here with the current software in over a year. At this point the best will we get is 1.40. I may come back if this software gets updated but for now goodbye.

Woody

Hey, I can not install the program. It displays "download failed, could not establish trust relationship for the ssl/tls secure channel". Is it my fault or do you have to update your certificate?

Stefan Heller

EDIT: Thanks! It works again! Sadly I get an installation error. Is there RTX 4080 support? Otherwise it would be useless to me. Some SSL Connections failed in the final installation process. Thanks!

Stefan Heller

Me too - great tool - sadly he seams to have vanished, did you get any answers?
