Hi there,


I am totally new to this topic and I might seem a bit silly, if so please be patient smile.gif


My gf bought me a Panasonic HC-V100 camcorder few days ago and I am quite happy with that all in all.
So far I have found only one "issue", which is when I play the videos back on my macbook pro / xbmc with LG LCD 3d tv ( PAL devices ).

Problem is that when I watch my videos I see a lot of horizontal lines which I think it is caused by interlacing. I documented myself a bit and found that this is quite normal ( source http://en.wikipedia.org/wiki/Interlacing#Problems_caused_by_interlacing , and this is what 's happening to me http://en.wikipedia.org/wiki/File:Interlaced_video_frame_%28car_wheel%29.jpg )

Althought it seems a normal behaviour, it does make the viewing experience a bit crappy to be honest.

I noticed that playing these videos directly fom the camcorder and using the tv as output I cannot see this problem, and this is thanks to the camcorder itself I guess.


Is there an option in software/something to do so that once you have your video ready on the sd card you can start watching without the need of doing some work on it ?

What do you guys deal with this ? Any suggestion ?




Thanks in advance

You did not say what software you are using as a "media player". Google for "Mac Media Player. One that comes up frequently is VLC. http://download.cnet.com/VLC-Media-Player/3000-2139_4-10210434.html. There are others.

The root of the problem is that your camcorder uses AVCHD formats that were developed and owned by Sony and Panasonic. Although becoming more universal, it seems Apple has been a little slow to fully wrap their arms around AVCHD with a full hug!

You need a computer video player that can correctly deinterlace interlaced video. On Windows I used to use CoreAVC driver, manually switching between deinterlacing modes (see here: http://www.avchduser.com/articles/watching_interlaced_video.jsp) Presently I use Splash, it is fast and it deinterlaces rather well.

I'm with Ungermann. Splash is a very nice video player if you are using Windows. They are working on a version for Mac OS.

You may say "a little slow", but it is 7 years already. I guess, Apple would rather prefer people shooting quarter-HD called iFrame. If you factor in the frame rate, which is only half of normal 60 Hz image rate, then you get one/eighth of HD. This is the format created for iMovie and AFAIK, can be edit natively by it. At least iFrame uses progressive scanning. The V100 can shoot in this format if anyone cares.

Hi guys,

thanks for the info!
I use vlc yes, sorry I didn't mention. I found that by pressing d on vlc you can change the interlace method, this way it works. As well as in xbmc there is an option to deinterlace automatically.


Thanks
