How to Convert MKVs to Lossless Editable Videos
I’ve come across many forums and comments asking “Is there a way to edit MKV videos to <insert video editing program that’s NOT windows movie maker>?” Let’s face it. Most of us including myself don’t want to rip DVDs or Blurays because it’s a lot more work to deal with. And to be honest, raw DVD footage isn’t that great because they’re interlaced in weird ways that sometimes are a bit difficult to restore progressive footage and almost always require cleanup using various filters from avisynth. Everyone would rather use downloaded footage however, due its file container and compressed codec, professional editing programs like Premiere and Vegas won’t accept them. This is where I come in. Here, I present you a conversion guide that will make things a bit easier. If you’re an AMV editor like me or whatever, I hope you’ll find this guide useful. This is how I do it.
Lagarith (in case UTvideo doesn’t work)
Make sure you install the latest version of these programs! DOWNLOAD
After you install all that junk, open up AvsPmod.
Next up, drag the mkv video file of your choice to AvsPmod. On a special note, the codec that commonly works is H264.
Once you drag the file, it should show up as something like this.
Now scrub the video a bit that’s on the bottom there. Depending on the video length, it may take a moment to show up the image. The first few scrubs may be blocky but that’s okay, it happens. Keep scrubbing at random parts until you see a clear image.
Now go to File > either “Save script” or “Save script as…” Both will choose to save in the same location where the video is located by default. This creates an avisynth file in the directory.
Now, we open up Virtual Dub. Drag the avisynth file to Vdub.
My Vdub is setup with two screens so it may look different for everyone else. After dragging the file to the program, scrub the indicator on the bottom to see the visuals. Again, pixelation and blocky scenes will appear so scrub to a clear image.
Next, go up to Audio > select “No audio”. Unless you plan to use the source’s audio, then leave it alone.
And here’s the most important part. Go up to Video > select “Fast Recompress”, then select Compression > select on “Ut Video Codec YUV420” > click Configure > check on “Same as # of logical processors” and select on “Optimize for compression ratio”. Click OK.
Finally, go up to File > “Save as AVI”, save it to where ever you like. Once that rendering window pops up, put the processing priority to Idle.
After it finishes encoding, the little window will disappear.
At last, you can finally edit the footage in Vegas or Premiere.
