Convert videos to 60fps (Updated 27 Sep 2014)

Sections:

Introduction:

Many modern TVs now include an extra frames feature, usually either 120Hz or 240Hz. This just means they take the source video, which is usually between 24-30FPS, and add new, interpolated frames between the original frames that make the motion look much more smooth.

High framerate (HFR at 48fps) was used in The Hobbit and will be used in upcoming films like the Avatar sequels, so why not watch all your movies at higher framerates?

A lot of people don’t realize this, but 99% of TVs made before this feature was introduced are actually capable of displaying 50FPS and 60FPS, and of course most LCD monitors display 60FPS as well.

This tutorial will allow you to convert videos of any framerate to higher framerates; 25FPS becomes 50FPS and 24/30FPS becomes 60FPS by default, or you can specify whichever framerate you want.

This script offers greater quality than any televisions I have seen.

I’m sure many people will want to see how well this script works, so here’s a comparison:
Original File
Converted File

Note: This can now be done in realtime using Universal Media Server!

Purpose:

This post provides instructions on how to easily convert any video to 60FPS, which allows you to take advantage of this feature of modern TVs on your computer monitor or TV without actually buying anything.

Step 1:

The files needed for this step are found in this zip folder (~3MB).

Run and install the file AviSynth.exe.
It is an early version of AviSynth 2.6 that is more stable and faster for multithreading than 2.5 releases.

Download and install MeGUI, run it, let it update all the things it wants to and import all of the presets.

Optional Tip: If you want MeGUI to update to the very latest stuff (at your own risk) you can push ctrl+s, go to the Extra Configuration tab, and in the Auto Update section select “Use development update server”

Close MeGUI and extract the files in the tools folder from our zip file into your MeGUI tools folder, which for most people will be either C:\Program Files (x86)\MeGUI\tools\ or C:\Program Files\MeGUI\tools\.

Step 2:

Download and install MKVToolnix.
When that is installed, run MKVMerge (Start Menu -> All Programs -> MKVToolnix -> mkvmerge GUI).

You will also need codecs installed. If you don’t already have them I recommend K-Lite Mega Codec Pack. If you install K-Lite, make sure to select “Profile 9: Lots of Stuff” during installation.

Step 3:

Start MeGUI again. You should be left with a window that looks similar to this:

step3

Step 4:

Push ctrl+r, or go to Tools -> AVS Script Creator.
Now you should see something like this:

step4

Step 5:

Click the Config button next to Avisynth profile.
It should look like this:

Step 6:

Click the New button down the bottom and type 60FPS in the name box, so it should look like this:

Step 7:

Now for the script that will do the actual 60FPS conversion.
Just copy and paste the following code into the text input area.

Setmemorymax(512)
SetMTMode(3,4)
PluginPath = "C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\"
LoadPlugin(PluginPath+"svpflow1.dll")
LoadPlugin(PluginPath+"svpflow2.dll")
Import(PluginPath+"InterFrame2.avsi")
<input>.ConvertToYV12()
SetMTMode(2)
<deinterlace>
<crop>
<denoise>
<resize>
InterFrame(Cores=4)

Important note #1: Make sure the path on the third line is correct.
For example, if you are running 32-bit Windows, you will need to modify the path to “Program Files” instead.

Important note #2: You should change the number “4” in the script (on lines 2 and 13) to your number of CPU cores. If you don’t know how many cores your CPU has just Google your CPU and you should be able to find the specs somewhere, or 4 should be fine anyway.

Important note #3: If you have a video card, you can increase the speed and quality of the script by adding “GPU=true” to the script.
So InterFrame(Cores=4) would turn into InterFrame(Cores=4, GPU=true)

Important note #4: This script always outputs either 50FPS or 59.94FPS (60FPS) for compatibility reasons. If you want to always double the framerate instead, so that for example 23.976FPS turns into 47.952FPS (48FPS), you can use the “FrameDouble” parameter.
So InterFrame(Cores=4) would turn into InterFrame(Cores=4, FrameDouble=true)

So now your window should look similar to this (with different text):

Step 7

Step 8:

Click the Extra Setup tab and make sure “Prefer DSS2 over DirectShowSource” is checked.

Optional tip #1: You might also want to choose your preferred resizer. For aspect-ratio changes (like from 720×576 to 720×480) a neutral filter like Spline36 will be nice. For actual resizing (like from 1920×1080 to 1280×720) a sharp filter like Spline64 will be best. I usually just leave it on Spline36. Make sure to untick the checkbox on the option after you change the default resizer, otherwise it will always be used by default which is often unnecessary.

Optional tip #2: I recommend changing the “MOD value used for resizing” to mod4. This gives the best balance between compatibility (a lot of devices like PS3 don’t have good mod2 support) and aspect ratio accuracy (the higher the MOD value, the more likely the aspect ratio is to be skewed more heavily).

Now it should look something like this:

Step7rev3

Then just click the Update button then the OK button

Step 9:

Now we’re back to the AviSynth script creator window and now that we have our 60FPS AviSynth template made and selected, it’s time to choose which video we want. Just click the button next to Video Input up the top of the window and find your video, then click Open.
A window will pop up with buttons, click the option on the right, usually either “DirectShowSource” or “AviSource”.
A window will pop up to show you the video, you can just close that.
Now you should see something like this:

Step9

Step 10:

Click the Save button. The video preview window might pop up again, you can close it again.

Step 11:

Now is the time when you need to choose the quality of the video and audio.

If you don’t know what to do here, something quick and easy is to just use CRF, which means you let the codec decide on the bitrates itself. So you can click the “Config” button next to the “Encoder settings” dropdown when you have a x264 option selected, then just enter a number between 16-20 in the “Quality” input box. 16 means your video will be almost exactly the same quality as the source, while 20 will look good too while taking up less space. Personally I use 16 for everything because why not? :)

So when you have your quality, click Queue in the Video encoding section.

Step 12:

Now your video is ready for conversion.
Now just go to the Queue tab and click Start down the bottom, then wait for it to finish.

Step 13:

The final step is to add your audio and/or subtitles from the original file to the converted file. This process uses muxing, not conversion, so there is no quality loss.
For this we will use the program we installed earlier, MKVMerge.
So run that and drag the converted file into that program, then do the same with the original file. If you can’t drag them on, you can use the add button instead.
Now you have several items in the Tracks, chapters and tags section. You just need to untick the ones you don’t want. Usually you will want to leave them all selected except for the original video track, as I’ve done in the following example:

Finally, set the Output filename down the bottom of the window and click Start muxing.
When that is done, you have your final video!

Final Thoughts:

This might seem like a long process, but actually it is only long once. Since we have now made templates, the process for the videos from now on will be much faster; instead of entering the script each time, now you can just make sure your 60FPS AviSynth script is selected.

This file can now be played just like any other video. I personally watch videos on my TV which is linked up to my computer using the awesome, free program called Universal Media Server, and that handles these 60FPS videos perfectly with no configuration.

Any comments are appreciated. If you can think of an improvement to the script, or to the process, or if you just found it useful and want to say thanks, please do leave a comment. I would love to know that it’s being used.

If you want to donate to help me with server costs and time spent keeping this article updated, you can do so here with my thanks :)





FAQ:

  • How can I fix random crashing of vfw4x264.exe?
    This probably means you are encoding a file using an input mode other than DSS2, which can happen if the clip is .m2ts or .dga (blu-ray) or another uncommon format.
    You can fix it by changing the 2 in the second line of the script to either 3, 4, 5 or just removing that line (try them in that order, since the options get progressively slower)
  • The option “Prefer DSS2 over DirectShowSource” is disabled. or
    I get an error like “can’t load avss.dll”.
    This means your computer is missing Haali Media Splitter. You can download it here or as part of a K-Lite Mega Codec Pack and the error should go away after you install it. If you install K-Lite, make sure to select “Profile 9: Lots of Stuff” during installation.
  • The file stops encoding after 99%.
    This usually indicates a codec configuration issue. Try installing/reinstalling K-Lite Mega Codec Pack, and make sure to let it select its preferred defaults (not “quick upgrade”)
  • Can I customize the output framerate to make it 48FPS, 75FPS, 120FPS, or anything else?
    Yes, you can choose any framerate you want. It is best to choose a framerate that is divisible in some way with the original video, but even that is your choice. You just need to add the options “NewNum” and “NewDen”, like this:
    InterFrame(NewNum=48000,NewDen=1001)
    NewNum stands for “New Numerator” and NewDen stands for “New Denominator”. In general, with NTSC material the NewDen should be 1001 and the NewNum should be 1000x your desired framerate (so for 48FPS you want 48000 and 1001) while for PAL content you might just want something like NewNum=75,NewDen=1 to output 75FPS content.
  • The output seems choppy, can I make it smoother?
    Yes, by default we output a video that sacrifices a little smoothness in order to reduce errors, but different people’s eyes pick up on different things so it can all be a matter of taste. You can try the InterFrame “Smooth” tuning, like this:
    InterFrame(Tuning=”Smooth”)
  • Why isn’t the GPU being used much in GPU mode?
    Only some things are done with the GPU in GPU mode, it’s still mostly done by CPU but helped by GPU.
  • Why is the video still the original framerate after running it through MKVMerge?
    You probably selected the wrong tracks in MKVMerge so you’re getting the original video track instead of the new one; make sure you untick the original video stream before muxing.
  • Why does MeGUI give an error “SVSmoothFPS: unable to load library given in ‘compose’ […svpflow_gpu.dll]
    Try re-installing your video card drivers.

  1. Hey, great guide here but I was just wondering if there is any way to stop the script from automatically cropping out the black backgrounds on youtube videos? It makes it less than 1080p and that makes me sad ;c.

  2. it worked for me..i tried it with a snippet from Anchroman 2 (because my CPU is garbba

  3. it worked ..i’ve tried it with a snippet ( (because my CPU is garbage it takes at least two hours to convert the whole movie) from Anchorman 2…it looks silky smooth

  4. When i press queue on the input tab after doing all the steps it says I need audio input,output and settings configured but they are blank. I’m taking it one of the files i downloaded at the start was meant to do this for me but it isnt? What do i do now as I cant go past this step without knowing what to select for those.

  5. I don’t know how to change the lines to “Program Files” i am running a windows 32bit machine

  6. Hello i’m going to sound like a plum as everything is working ok but want to try to make the video smoother by using the InterFrame(Tuning=”Smooth”) but not sure where to put in script

    Do i just add InterFrame(Tuning=”Smooth”) at bottom of script just below InterFrame(Cores=4) or does it have to be added to the InterFrame(Cores=4) part

  7. I’m using a 144Hz monitor and i would like to at least try watching movies at 144FPS. Is there a way to use this script to convert videos to above 60FPS?

    @Kokuten I’m glad you got it fixed :)

    @Chloe that’s great :) You can use the MeGUI script creator to resize, or you can manually replace the line <resize> with something like Spline36Resize(1280,720)

    @Stephen Looks like a codec issue, you can try (re)installing K-Lite Mega

    @Anime Viewer thanks, I’ll try to make it clearer

    @TheFakeCake the script doesn’t automatically crop anything, it probably just means that the video didn’t have black bars in the first place (YouTube will add black bars to its video player just because it’s better to have a color than transparency).
    You can add black bars if you want but I don’t recommend it, and even a video that is 1920×2 is still 1080p by the way – 1080p is a movie that has either 1920px width or 1080px height, doesn’t have to be both :)

    @DJ it looks like you’re pressing “AutoEncode” instead of “Queue” :)

    @Tony I’m not sure what you mean, you just use the keyboard like normal :)

    @Eyerex like this: InterFrame(Cores=4, Tuning=”Smooth”) :)

    @Rokushino please see the fourth point in the FAQ section :)

  9. Thanks so much! I’ve been using SVP for live playback, but want to convert some of my movies to 48fps (the hobbit of course), so I can play them anywhere. Works perfectly!

  10. I am stuck on Step 10. I was wondering if you can help or if you have any idea.
    On step 10 when I click save I get this message: http://gyazo.com/2e3cc7d09954b6cb5120acdc95a59d4b

    If you know a fix for this, that will be greatly appreciated. Thank you.

  11. I have a problem. Do you knwo what can I do about this?

    Here

  12. moi j’ais un problème avec mes vidéos! je suis bloqué à l’étape 9! lorsque je clique sur une vidéo,le logiciel m’indique cela: The file DirectShowSource(“C:\Users\ANY-3D\Downloads\[ReinForce] Tokyo Ghoul – Vol.1 (BDRip 1920x1080p x264 FLAC)\Extra\PV\PV4.mkv”, audio=false, convertfps=true) cannot be opened.
    Please make sure it’s a valid AviSynth script and that AviSynth is properly installed.
    You can check the validity of your script and AviSynth installation by opening the file in your favorite media player.
    If that works, try opening the video in VirtualDub(Mod) as well. If the former works and the latter doesn’t, install a YV12 codec.
    Error message for your reference: Impossible de charger la DLL ‘AviSynthWrapper': Le module spécifié est introuvable. (Exception de HRESULT: 0x8007007E)

  13. I have a peculiar problem: my video preview is grey without giving video, and when the job is started (mux-ing is job 2 on it as well?), it produces a file of 5– kb and is grey. ‘Prefer DSS2 over DirectShowSource’ was not a clickable option, so I will try your troubleshooting guidance firstly.

  14. Hi! Thanks a bunch for this guide! I have a question though. For every single one of my videos, after I create the Avisynth script, the video comes out with flashing colors. Like it’ll be flashing from the normal color to black and white. I tried unchecking and checking the color correction box in the script but it doesn’t change anything. I was wondering if I screwed up something in the script/settings or if the videos I’m using just aren’t perfect for the program (I’m using .mkv files). Thanks again for this awesome guide!

  15. Is there a way to convert a stereoscopic video in over-under format (1920*2160) without it being squished to 1080p?

  16. SubJunk

    November 5, 2014 at 2:23 pm

    @Mithy it shouldn’t get squished in any circumstances. For OU content we just halve the video and separate interpolation on each half, we don’t change resolution at all :)

    @jejh @Arman @Luke try installing K-Lite Mega, it sounds like a codec is missing or not configured properly :)

    @Gibson what’s the problem?

    @Michael thanks for the feedback :D

  17. All that happens in Step 9 is that MeGUI refuses to open a video file, gives an error message saying that none of valid video files i’m loading are valid, then stops responding and crashes.

  18. It gets stuck right after it starts preprocessing at 0,00 % without any error message. How to fix it?

  19. @SubJunk
    Thanks for the reply! The problem was that the video was actually Half-OU set to 8:9 aspect ratio, so all I needed to do was fix the AR with mkvmerge after conversion.

  20. Hmmm I still have the same problem after reinstalling the K-Lite Mega pack. Could there be something that I have to change?

  21. hey bro, everything is just fine until i get an error message while opening the video file in Avisynth Script editor,
    it says ( Could not open the bla bla bla…., the file name, directory name, or volume label syntax is incorrect)
    how do i solve this?
    thanks BTW

  22. Question regarding script code “.ConvertToYV12()”
    Shouldn’t it be:

    ConvertToYV12()”

    And one more about SetMTMode (2). Should it really be after ConvertToYV12() or it should be right before? Because Xvid4PSP puts it before and SVP developers suggest it to put right before.
    TY!

  23. Thank a lot!!!
    Can you make a VideoTutorial of this beautiful guide?

  24. For those getting the “can’t read the video stream” error message :
    If you have added “GPU=true” in the script, remove it.

  25. SubJunk

    November 21, 2014 at 9:38 pm

    @REM1X @iwrtu @jejh you can installing a newer version of K-Lite or installing it in Safe Mode, or selecting different decoding options in the advanced K-Lite settings for the problematic filetypes.

    @Andrew it could mean there’s a special character in the filename, or just that it’s wrong

    @Ajvar I don’t think it makes a difference? I’m open to comments and improvements if it turns out there’s a better way :)

    @Jacopo I don’t have plans to do a video, you can do it if you want :)

    @MMM I’ve started a thread on the SVP forums to try to fix this issue, we aren’t sure yet what causes it but it may be recent video card drivers. The thread is here if you want to join http://www.svp-team.com/forum/viewtopic.php?id=2233
