DV import and Compression

[Wolfpack]

Allo,

DV is the lowest compression for loading rushes. There is no point in deinterlacing, since the result goes to a interlaced device. There is also no size difference between hdv and dv, hdv is better compressed. I always recompress HDV footage to HD 8bit.

For the space problem, I would suggest to buy drives, 60 Gb on local drives is little for editing. Like for example, al of our editing computers have at least 250 GB and still they need extra space. (like 2.5 TB or 12 TB network drive sollutions)

Magic bullet is a compressor for HD loading carts, it is no use for you, since you're not going uncompressed editing. Use the generic DV pal firewire device.

So the sollution is:

Do a viewing, write down the timecodes of the parts you're going to use, and do a batch capturing with those timecodes. No point of capturing 3 hours of footage if you only going to use 15% of it. Also are the chances of your computer crashiong during the capturing of that amount of footage very very high. We only capture max 5 minutes a time in the batches.

See if it can help you...

Greetzzzzzzz

Hello all.
There is no point in deinterlacing, since the result goes to a interlaced device.Strong disagreement here, there is all the reason in the world to deinterlace, but that's a matter of taste.

Interlaced footage showed on an interlaced TV screen will have twice as many fps as deinterlaced (not technically, but to the eye), which unmistakably makes your work look like news- or amateur footage. (and typically, you don't want this, unless you're actually filming news footage or your sister's wedding ;) )

Deinterlacing will drop this to 30 fps (NTSC) or 25 fps (PAL), which looks more like the 24 fps of film.

Bottomline, deinterlacing is the first and most important step in going for the ever-so-discussed film look.

:)

There is no point deinterlacing the DV footage because it is PAL, and is not interlaced.

The HDV footage on the other hand should be deinterlaced as it is an interlaced format (depending on the camera). If you are doing any effect work full frames are easier to work with.

Also, if you don't deinterlace you will have a mix of interlaced and deinterlaced and that can cause an issue primarily when watching it on a progressive DVD player into an HDTV.

Especially with the amount of people watching on widescreen HD TV's. By deinterlacing, your footage will look a little better when the TV increases the size of the image to cover the whole display.

Thanks guys.

Your replies helped a lot.

The PAL standard is 720 x 625 at 25 progressive frames per second. If the footage you are working on is interlaced then it is not PAL. The footage you are working on must have been converted at some point.

What camera footage have you used? Is it the source footage or a Dub?

If the footage you are working on is interlaced then it is not PAL.

The official PAL standard might be progressive, and the actual storage might be progressive as well, but the video data itself can be just as interlaced as NTSC, and every single PAL camera on the consumer market (including HD), and most professional camcorders too, shoot and store interlaced PAL frames - and therefore, the footage needs to be deinterlaced if you want to avoid the home video look.

A trained eye can tell just by looking at the footage running on a TV screen, but if you don't believe me, grab a frame and zoom in on it. ;)

PAL stands for Phase Alternation by Line, and was adopted in 1967. It has 625 horizontal lines (576 visible lines, the rest being used for other information such as sync data and captioning) making up the vertical resolution. 50 fields are displayed and interlaced per second, making for a 25 frame per second system.

there are DV camcorders that can shoot progressive such as the panasonic DVX100... but that's not standard PAL...

I stand corrected, I was going on an assumption, and as I don't ever use PAL, I don't get the chance to see it on a TV screen.

My trained eyes have not yet had the oppurtunity.
