Many of the latest models of LCD 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 and X-Men: Days of Future Past, which will use HFR at 60fps, so why not watch all your movies at higher framerates?
A lot of people don't realise 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.
This script offers greater quality than any televisions I have seen.
Note: This can now be done in realtime using Universal Media Server!
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.
The files needed for this step are found in this zip folder (~6MB).
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.
Close MeGUI and extract the tools folder over the top of your MeGUI tools folder, which for most people will be C:\Program Files\MeGUI\tools\.
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.
Start MeGUI again. You should be left with a window that looks similar to this:
Push ctrl+r, or go to Tools -> AVS Script Creator.
Now you should see something like this:
Click the Config button next to Avisynth profile.
It should look like this:
Click the New button down the bottom and type 60FPS in the name box, so it should look like this:
Now for the script that will do the actual 60FPS conversion.
Just copy and paste the following code into the text input area.
PluginPath = "C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\"
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.
Important note #3: If you have a recent video card in your computer, you can increase the speed of the script by adding ", GPU=true" to the script.
So InterFrame(Cores=4) would turn into InterFrame(Cores=4, GPU=true)
So now your window should look similar to this (with different text):
Click the Extra Setup tab and make sure "Prefer DSS2 over DirectShowSource" is checked.
You might also want to choose your preferred resizer. For aspect-ratio changes (like from 720x576 to 720x480) a neutral filter like Spline36 will be nice. For actual resizing (like from 1920x1080 to 1280x720) a sharp filter like Spline64 will be best. I usually just leave it on Spline64.
Now it should look something like this:
Then just click the Update button then the OK button
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 to give you 3 buttons, click "DirectShowSource".
A window will pop up to show you the video, you can just close that.
Now you should see something like this:
Click the Save button. The video preview window might pop up again, you can close it again.
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 Enqueue in the Video encoding section.
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.
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!
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 PS3 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 me, you can do so here:
- How can I fix 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 Codec Pack (I use Mega) and the error should go away after you install it.
- 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.
This probably means your codecs aren't configured properly.
You can fix it by uninstalling any codecs you have, restarting your computer, installing a K-Lite Codec Pack, and restarting your computer again.

- Added a common question to the FAQ; "Prefer DSS2 over DirectShowSource" is disabled.
- Increased accuracy of the Quality script

- Added the ConvertToYV12 function, just meaning MeGUI doesn't need to keep adding it all the time
- Significantly reduced tearing in high-motion scenes using the Quality script. Here are comparisons of interpolated frames:
Comparison 1, old script, comparison 1, new script
Comparison 2, old script, comparison 2, new script
It's almost unbelievable they are the same frames, but they are.
- Speed of the Quality script has also increased
- Input uses SetMTMode 2 now instead of 1, since 1 can cause quality problems for .avi files.
- Reverted to always using 60FPS. Using divisible framerates did provide increased accuracy with technically the same level of smooth motion, but monitors and televisions can't display those exact framerates anyway which results in less visible smoothness. Thanks to Widezu for pointing this out.
- Added to the FAQ
- Minor wording changes
- Increased accuracy of both scripts by allowing for different framerates depending on the input. See here for more details.
The videos still play perfectly on 60Hz and 75Hz monitors/TVs, so don't worry about that.
