What is the crowd's opinion of slowmoVideo?

I am learning how to use slowmovideo it didn't work out the best but I slowed down the scene where you can see her tits to just under 15 seconds for gfycat I'll link anyway:

Without being an expert, this is what I think:

1) Sounds about right. Don't think the noise will be as much as you expect -- source: I'm used to shooting ISO 12800, 6400 and 3200 in a Canon G16 which has a sensor with 1/10 the area your sensor has -- it's ugly, but manageable.

2) I'm a bit lost here. "Ultra smooth" is usually considered for 48+ fps, if anything 24 fps would give a "less smooth" result. Why not 30 fps? If the frame is relatively still you can apply frame interpolation (with Twixtor or slowmoVideo) and push it to 48 fps without changing your plans. Under good conditions, a 2x increase in frames while keeping the same length of video gives a smooth result without making the artifacts noticeably. If you want to see what kind of artifacts these softwares create, get one of them, interpolate to 10x frames and playback at 1/10th speed -- it's similar to a morphing effects between frames.

3) No experience here, sorry.

4) Just apply batch processing after tweaking a few of the shots and applying the same settings to the following pictures. Then you go to sleep, cause it will take a loooong time. And storage. If you can affor that, I don't think RAW is overkill -- it'll give you better image quality and more control over the source material.

5) Take your time to learn the After Effects tools you'll need. It'll save you lots of time, and as you said, being another Adobe program the UI isn't that much different from Photoshop. AE has been made specifically to process video and is optimized, both in workflow and operations, to make this easier for you.

Looking forward to seeing the end result!

Hi MrSquig, linear interpolation may not work so well from 4 frames / sec to 25/30. That's why we're looking into slowmovideo which does warp based interpolation (I think).

Still, maybe that's an unfair assumption. Have you tried interpolating a few frames from the MARDI sequence?

> I forgot to mention, I also have a python script written that downloads all the MARDI frames to your computer.

That's why I wanted to create a repository, I wrote one too! No need duplicating efforts on something so trivial :)

Have you considered adding the motion blur through frame interpolation instead? http://slowmovideo.granjow.net/

The downsampling from the additional frames aren't really used and you can easily simulate that effect using sampling methods without needing additional frames in the recording itself.

The problem is there is too much motion and not enough frames (to make it smooth).

I pulled 15 frames from the episode (.6 seconds) and ran it through SlowmoVideo.

My first attempt was a ping pong of the entire 15 frames with a Bezier curve at both ends (so it would decelerate the motion).

That really smoothed it out but it still feels like too much motion. The cinemagraphs that I really like have a more subtle feel to them.

So I picked out a smaller range of motion and rendered again. The result is much more appealing I think.

I use Cinelerra mainly. Both Cinelerra and Kdenlive are videos editors. They have lots of overlap in a lot of functionality. I am trying to fully switch to Kdenlive, but it is taking time. I use blender to create 3d titles and other fun effects. I use slowmovideo for ultra slowmovideo video. The final product looks just as good as twixtor to me. However, slowmovideo does take a little more work to learn. You won't find too many tutorials out there for it.

Twixtor has always been hit or miss for me. It’s easy enough to get a good result but if you want to adjust it later it just explodes in your hands and gets wonky quick. So if it’s not working for you then try something else, like After Effects, Fusion (in DaVinci Resolve) or SlowmoVideo. I’ve actually had extraordinary good luck with the time remapping built into FCP X; it’s quite impressive.

Good luck.

OpenShot does have the ability to set the time rate of frames in a clip. The Time function in OpenShot takes into account the entire clip that is being edited, not just the portion that you want to use.  To work around this issue, you can export the part of the clip that you want the speed adjusted to a separate video file.  Create a new project and import only the clip to be adjusted.  Change the speed of that clip then export it as another video file.  Import the recently adjusted clip to your original project and add it to the timeline.

You might find it easier to use another Free and Open Source Software such as slomoVideo to slow your video by speeds not built into OpenShot.

As this is a linux sub I'll say it again, wait till october/november when SVP for linux will be out. It's supposed to have a 1 click "export" button that will do what you want. What you want is typically done in windows with avisynth, ffdshow, and tmpgenc. I would put the difficulty at intermediate to advanced. You're better off just waiting or trying the svp 4.0 beta.

You could try something like this. I would expect you'll have to reclock the video and remux the audio back in and there is a risk the audio could get out of sync. Again I put the level of difficulty at intermediate to advanced.

I used this guide: http://ryankennedy.io/running-the-deep-dream/

The zooming-in-image-series is part of that guide.

Then I used http://slowmovideo.granjow.net/download.php to make it smoother (i.e., add frames in between the real frames). That also added the glitches near the border of the images.

Ah, I'm very excited! this is the program which I was referring to. It uses motionflow technology to actually interpolate the motion frames! There's a separate program that can do it, but it's failed on both my computers. Can you get it to work? http://slowmovideo.granjow.net/faq.html
