Hello,

I have one question for HD7 users, anybody noticed original recorded file in HD7 mean .tod files actually are progressive scan instead of interlaced? If we play original .tod files in Window Media 11 than they are so smooth and very much clear, and if play same converted files supplied CyberLink's PowerDirector software than they looks interlaced! Clearly we can see horizontal lines!

I do not understand if CCDs are progressive then why JVC converted them into interlaced as final MPEG2 output?

This is a function of the conversion method. Steve would know exactly how to handle this but from what I saw there is no need for conversion as such. The software generates a .mpg all on its own which you can import into almost anything.

Yes, but did you notice? .tod files looks very smooth in WMP 11 but converted .mpg files shows horizontal lines (interlaced). So question is why .mpg output shows visible horizontal lines! Is original .tod files are actually progressive? So it is better to use original .tod files?

And because of this I always make .tod files after editing, I am assuming all guys who owns HD7 knows that we can make .tod files (GZ HD series). Supplied PowerDirector can make original .tod files.

WMP is the problem. Look at viewing the files with other codecs and other players. Then again I dont know your setup.

Did you buy Steve's book ?

I do not think WMP has problem, since it is playing absolutely fine HD7's original .tod files! So my question is that why converted files shows horizontal lines (Interlaced)?

And originally, my question was that if HD7 captures videos in progressive mode than why JVC converted them into interlaced?

Haven't worked on a Windows machine for years, but is it possible that WMP is de-interlacing the files while playing?

Exactly my thought.

Exactly my thought.

I am afraid but I have installed PowerDVD Ultra, VLC player in my Laptop, both shows horizontal lines! Do I need some software to be installed?

And I am repeating again & again my main question is why original files works smoothly in WMP and doesn’t show interlaced lines? So it means .tod files actually are progressive? Since HD7 has three progressive CCDs! It record in progressive, and convert them into interlaced, but why? If it is true then why JVC converted them in interlaced?

I guess the idea behind WMP's de-interlacing is that many users would b*tch at Microsoft about lines in their files.
As far as I understand is that the HD7's output IS interlaced.

Normally, your editing software should provide you with de-interlacing during rendering if your footage is aimed to be watched on a computer screen.

Except for Avid Media Composer all NLE show only 1 field of video on your computer screen.

Interesting ... how is de-interlacing working then? I always thought it combined the two fields.
Or did I get something completely wrong? ... It is a long time ago since I read the last book about video.

I still have not received any answer to my question! Huh!

I have the feeling that only JVC would be able to answer that question.

There are a dozen ways to deinterlace so a proper answer would be a very long one.

In an NLE where a "monitor" is about a quarter the size of the screen, dropping one field makes the most sense. Players, like VLC and the QT Player, give you a choice. VLC gives you many choices. However, none of the choices are documented so good luck. :)

Bottom-line, you should never see interlace on ANY display or on ANY TV. The exception is FLASH in your browser which seems to have no settings. Other players should allow you to find a setting that looks good.

I still remember last year when this camera was introduced, one early user of HD7 has proved that HD7 is actually prograssive recorder! I will try to find out that post and will post here.

But anybody noticed same what I ? Means original .tod files are so smooth whereas converted MPEG files shows interlaced lines!

Kaushik

I think it's the Widows Media Player that is making them 'look' de interlaced.

If I play original .TOD files in Quicktime on a Mac, they are interlaced, I see the jaggy lines they are not smooth.

Whatever but .tod files are superb in WMP.

The CCDs on the GZ-HD7 are progressive scan CCDs, but the for some reason they decided that when capturing, the internals in the camera would convert the progressive into interlaced. WMP 11 is automatically set to "de-interlace" videos, even DVDs. Its great because I view older DVDs that are interlaced and when WMP 11 de-interlaces them, they look smooooth. Check your settings, you will see that de-interlaced is checked or set somewhere (I cant remember where or how, Im a Mac user). What I do with my files is edit in FCE 3.5, export as a Quicktime Movie, then using an Encoder/Transcoder software I export it to de-interlaced, 1920x1080 HD and it looks pristine!! But yea, remember, WMP 11 de-interlaces videos.

I am afraid but what are .tod files? Progressive or Interlaced? If they are progressive than how WMP 11 is dealing with it? And if .tod is interlaced than why they are not showing horizontal lines while playing in WMP11?

And converted .mpeg files are showing horizontal lines in WMP 11, why? If WMP is actually set de-interlace the videos than why showing horizontal lines?

I am not getting proper answer!

The previous post gives you the answer.

There's no reason for recording P because the camera records 60I. There's not a lot of love for 1080p25 and 1080p30 by the Japanese companies since it is a fringe part of the market. The next step is 1080p50 and 1080p60 but that requires parts past the CCD that can run with 2X more information. Maybe 2009.

Ok, but my question was different, I would appreciate if you can read it and reply!

I told you above. The CCDs are progressive, but the camera internals changed the image to interlaced. You can de-interlace the video once you have them downloaded to your computer. I take my .tod files (which are interlaced) and then de-interlace them and they are the exact same size, resolution and format (FHD, CBR, SP>whichever I record in) but now non-interlaced. You can set your WMP to NOT de-interlace your video and you will noticed the lines. Im using a Mac and I can de-interlace DVDs using the DVD Player in my Mac and the pictures no longer look interlaced. Try it out, you can see it WELL with Titles. Watch a movie and when titles are changing/flipping/flying stop it...you'll notice the interlacing. Uncheck interlacing and go back...it will be smooth.

If you want an answer to your question, no we have not noticed that because the .tod files are NOT actually progressive, they are interlaced.

Because they felt like it maybe(seriously)? When this camera first came out, there werent too many progressive HD cams (consumer at least) out there and it also seems like its not until recently that your average consumer is NOW understand 1080i vs 1080p. In electronic stores like Circuit City and Best Buy, I had not seen a progressive movie on a 1080p screen until AFTER the Blue-Ray & HD-DVD war was over

Gary's correct --d has given you the same answer I did. There are NO 1080p60 cameras. The parts between the CCDs and the encoder only handle 1920x540 images. They would need to be 2X more powerful to handle 1920x1080 at 60fps.

Today, only 720p60 and 1080p30 are available.

Well...there are no consumer 1080p60 cameras. If only the Red One camera cost $1499, like the GZ-HD7 was, wow! Soon enough there will be consumer cameras like that shoot 1080p60, but by that time, everything will probably be like the Red One which is 4k and soon next year 5k resolution. Cameras like the Red One are suppose to be SEMI-Pro, though I would called them Pro period. The Red One package is a total of about $25 grand, which is great for amateur film making.
