Reduce interlace flickers on your TOD videos from JVC camcorders!

Home video shooting is more and more popular these days. It seems that everybody can keep your wonderful memories in a video. But it still needs some skills to make good videos and keep nice quality. This article is to tell you the way to play your videos from JVC camcorder and share with others with the best quality. You can convert the JVC video to other formats and if you are using JVC GZ-HD7, JVC GZ-HD3, JVC GZ-HD5, JVC GZ-HD6, JVC GZ-HD30, or JVC GZ-HD40, you will get videos with .tod extension, and you will find this article especially for you. TOD video is high definition video which is stored in MPEG-2 transport stream container files with TOD extension. In most other systems these files have M2T extension. TOD format is comparable with AVCHD, but cannot be directly played on consumer video equipment. And besides, you will get some interlace flickers while playing on your computer. This article is to tell you the way to reduce these interlace flickers on your TOD videos from JVC camcorders, and play them on your Mac OS.


What is interlace flicker?



Interlace flicker is the narrow lines you see while there is a fast movement or panning on the video from your JVC camcorders playing on your computer. The reason why you get this is because the camcorder is using interlaced scanning to record and your computer is using progressive way to play it. The following is the detailed description of interlace scanning and deinterlacing from avchduser.


“A television set creates image on the screen line by line. In traditional television all lines on the screen are not drawn or scanned in sequence from top to bottom, instead every other line is scanned. This method of display is called interlacing. With interlacing, an entire single image called frame is shown in two interlaced scans, each scan constitute a video field. Compared to non-interlaced or progressive television, interlacing allows using higher scanning rate within a given bandwidth. Higher scanning rate reduces flickering and allows to portray motion more naturally.
Interlaced scanning produces a visual defect called combing when objects in the image move around. With a traditional CRT-based television combing is not noticeable because fields are shown as series of fast flashes, caused by moving electronic beam, and also because scanning lines overlap a bit.

Modern LCD and plasma displays work differently than CRT displays and cannot display interlaced video natively. To avoid combing, interlaced video must be converted to progressive before it is presented to a viewer. The process of converting interlaced video into progressive is called deinterlacing.”

How to reduce the interlace flickers?

In order to reduce the unwanted narrow lines on the video, you must deinterlace the video. There are several ways to deinterlace.

  • You can use a video card with built-in deinterlacing;
  • Use a video driver or codec that is capable of deinterlacing;
  • Use a video player that has built-in deinterlacing engine;
  • Convert interlaced video to progressive. This will allow you watching video on any computer with any hardware and uploading to different online sites. This is the easiest and most useful way which I’d like to recommend here.
