SVPflow motion interpolation (Avisynth + Vapoursynth, Linux, Mac?)

[amayra]

can you give full list of new features ?

Picture quality is the same as with SVP ver.3.

No quality improvements? Shame

Alchemist OD (software version of their expensive hardware box) gained quality and now clearly outperforms SVP (for the cost of speed and resource requirements).

Also- is it just my imagination or SD content keeps much better quality than HD after SVP conversion (are there some internal compromises on SD+ frame sizes)?

HD content does contain more accurate data on what's actually going on, but this comes at the price of having to do many more calculations to come forward to the same results as SD.
And since pretty accurate motion estimation on SD is already pretty expensive, getting the same kind of quality in HD would be really demanding on the hardware.

For file conversions SVP speed is very good, so I'm happy with eg. 3x slower mode which will also keep relatively good quality on HD.
I'm happy to do some test- got access to K80 Tesla card

is this project is no long open source ?

What makes you think that? From the SVP website:

svpflow1

This is a motion vectors search plugin which is a refactored version of MVTools2 2.5 so this plugin is distributed under terms of the GNU GPL license.

svpflow2

A closed-source frame rendering plugin.

It has always been this way, as the documentation states, you can find the svpflow1 source code here: http://www.svp-team.com/files/gpl/svpflow1-src.zip

I am completely confused by this!
How do I use SVPflow to change fps from 60 to 50 without involving the GPU?

Thanks.

Floaty, try Interframe if having problems, is simple. Just put dll's in Plugins and also the Interframe2.avsi script, then simple as

num=30000   # EDIT: or for 50FPS num=50 den=1
den=1001
Cores=4
Interframe(NewNum=num,NewDen=den,cores=Cores)

from Interframe2 script

function InterFrame(clip Input, string "Preset", string "Tuning", int "NewNum", int "NewDen", bool "GPU", string "InputType", 
    \ int "OverrideAlgo", int "OverrideArea", int "Cores", bool "FrameDouble") {
	# Defaults
	Preset        = default(Preset      , "Medium")
	NewNum        = default(NewNum      , 0       )
	NewDen        = default(NewDen      , 0       )
	Tuning        = default(Tuning      , "Film"  )
	GPU           = default(GPU         , false   )
	InputType     = default(InputType   , "2D"    )
	OverrideAlgo  = default(OverrideAlgo, 0       )
	OverrideArea  = default(OverrideArea, 0       )
	FrameDouble   = default(FrameDouble , false   )

[Floatingshed]

Hello, thanks for the suggestion, but I seem to have an unidentifiable issue with interframe.

I encode to h264 but the encode stops at random points each time, no obvious reason (sometimes after a few frames, sometimes after several minutes or an hour). If I use motionprotectedfps I have no problems, I could use this but was looking/hoping for a more modern filter with fewer artifacts...

[StainlessS]

Just curious, does stop if rendering to lossless avi via for instance ut-vidio or magicyuv ?

[Floatingshed]

No it doesn't, in fact that is how I have been getting around it, render to lossless then run a second process to convert the lossless to h264. I am guessing that it is a memory issue but there's nothing obvious (to me anyway!)

[StainlessS]

@FloatingShed, Could this perhaps be related to you issue:- http://forum.doom9.org/showthread.php?t=173908

Perhaps get together and compare systems.

EDIT: I dont know what SVP player is.

EDIT: Full quote.

svpflow1 in svp-team in website is 4.0.0.128 and in "SVP 4\plugins" have 4.0.0.132

@chainik_svp

According to the changelog here, there's been a handful of updates to SVPflow. The first post and the the download section of the SVP wiki still list version 4.0.0.128.

SVPflow - 4.1.0.141 - 2017-04-05
= fixed high CPU load with frame interpolation off

SVPflow - 4.1.0.140 - 2017-03-03
+ rendering in 10 bit color depth (Vapoursynth only)

SVPflow - 4.0.0.137 - 2016-08-25
= fixed random crash in mpv and VLC

SVPflow - 4.0.0.136 - 2016-08-18
= fixed video corruption with smooth.cubic=0

SVPflow - 4.0.0.135 - 2016-04-30
= Win: fixed random crash in some cases

SVPflow - 4.0.0.132 - 2016-03-18
- Win: dropped legacy Avisynth 2.5 interface support
+ Win: added SVConvert function in 64-bit version

SVPflow - 4.0.0.131 - 2016-03-04

SVPflow - 4.0.0.129 - 2016-02-23
= fixed crash with SVPlight enabled

[kolak]

Looks like anything above 4.0.0.128 is not available for download.

https://www.svp-team.com/wiki/Plugins:_SVPflow

still shows 4.0.0.128 as latest version for download.

[cork_OS]

Here are svpflow libs from the latest SVP4 update: https://www.dropbox.com/s/9wjx4uq07s...pflow.zip?dl=0

[Selur]

@cork_OS: do you also have the latest libs for Vapoursynth?

No, but MysteryX have just asked Chainik to update the libs:

But I agree that it should be updated. We'll do it soon enough...
However there's nothing useful in the Avisynth part since rev.128

# adjusting frame count with Interframe/SVP

# Output
clip.set_output()

I get a 'Python exception: SVSuper: Clip must be YV12' since I wanted to stick with 4:2:2 for the output I was wondering:
What would be the most lossless way to apply Interframe/SVP and getting 4:2:2 as output?

[MysteryX]

SVP supports only YV12. If you want to use it, you need to convert to YV12 and can then convert back to YV16 if you want.

Alternatively, my implementation FrameRateConverter supports YV16 or YV24, but is much slower especially with multi-threading -- but with considerably better quality.
