Video Deinterlacing: Tony Hawk's Proskater 4

This video compares interlaced and deinterlaced video. When interlaced video is played on a progressive screen, such as your computer monitor, you can see horizontal combing as the image moves. If you deinterlace the video however, this combing is no longer visible and the video's full motion is revealed.

I used Tony Hawk's Proskater 4's 3 intro videos to demonstrate this. These videos are interlaced, as this game cannot run in progressive mode. In the source videos, the information of 2 frames are combined into 1 and they are played back at 30 frames per second. Deinterlacing with the method I used seperates the combined frames, doubling the frame rate to 60 frames per second. This higher frame rate is twice as fast as the original, making the video look much smoother than it did before.

Here I used VirtualDub to deinterlace. I used the Bob Doubler filter set to Adaptive ELA. I had to do quite a bit of experimenting to find the method that works best.

Although the deinterlaced video's motion is very fluid, you can't notice it because YouTube caps its videos at 30 frames per second. Here is a link to the video at the full 60 frames per second. This will play in Windows Media Player or a similar program if you have an Xvid decoder installed.

@stevoisiak Me too. Just not Pro Skater 4. I've beaten every goal in that game twice. I COULD play it again though, since I have it right behind me.
