DV vs HDD recorders

Dear CS'ers.

As above, I know nuts about videography, but how does DV/MiniDV compare wth HDD recorders? Seems like most pros (wedding videographers) are still using DV/MiniDV but my simple thinking is that HDD would make post-processing/editing much easier?

Cheers
 

hi dionysis, I m no expert but will try to answer u from the best of my knowledge. Anyone pls correct me if i am wrong.

yup, hdd is easy for post processing and editing.

most HDD cams compress video captured into MPEG-2 format, that is DVD type format. by using miniDV, video captured are at their truest form (highest quality). It is better to have uncompressed video so that the quality is not lost. now even High-Def footages can be captured into miniDV. you can change tapes while shooting but what if your HDD is spoilt?

miniDV takes a longer time to transfer from tape to PC. And it does take longer to burn raw footage into DVD as compared to an already compressed MPEG2 footage. miniDV takes a whole lot of space in your computer. 1hr of footage is around 13Gbs. A DVD, as we know, is only 4.7Gbs.

So it depends on what you need. Do you want to save time or quality? Do you want better control with raw footage or contented with compressed footage for easy burning to DVD?

whatever it is, dont go for DVD camcorders.
 

DV format is not raw or uncompressed. DV is a codec that compresses at 25Mbps.

HDD is fast and easy for file transfer, but editing MPEG2 files is not as smooth as editing DV.

Some HDD cams record as AVCHD, not MPEG2. This format is even worse than MPEG2 to edit. Can be done but no fun.

HDV records on miniDV tape, but using MPEG2 transport stream, not DV. Data rate is same as DV (or similar anyway) so recording time per tape is the same.

Some pros get the best of both worlds by adding an external harddisk like Firestore to a miniDV camera. You still have a tape backup of your footage, and you still have the fast file transfer times of a hard disk. And FS drives can also be used with HDV cameras (if you choose the correct model).

My own prediction is that before hard disk becomes THE standard for video cams, it will be superseded by flash memory card storage. When the price of cards becomes more affordable it should really take off as a storage medium.
 

jaegersing,

thanks for the enlightenment. Panasonic now has the HVX rite? so you think that its p2 cards is the way to go. that means the hvx is a good investment then?

Hi smartmat. At the risk of being flamed (panasonic guys can get quite passionate about their cameras :) ) I would say no. P2 cards are proprietary and very expensive and are based on PCMCIA interface which is already obsolete. I'm not sure if Panasonic are going to keep on releasing new models of camera with P2 format cards, and I would not recommend buying HVX thinking this is the way of the future. Of course the HVX is a good camera, I'm not saying anything against it, it's just that technology-wise it could easily be a dead end.

So what else is around.? Well, Sony has just brought out the EX1 with Expresscards which are the successor to PCMCIA, and they have partnered with one of the leading flash memory card product houses. So it is more likely that this type of card will take over, and drive sales to the point where they become mass market and therefore much more affordable. If (when) this happens, it will be great news for us all.

At the moment, I am using a Canon HDV cam which is quite decent, and I am prepared to wait and see what happens next before I choose another cam. I tried out the EX1 and it is very nice, but the current cost of memory cards (estimated, cos the Sony staff would not give a price) puts it off of my radar scope at the moment.
 

honestly i would just go for dv because the bigger file gives you more options to what kind of further compressing you want to make it into. I have found mpeg-2 hdd camcorders hard to edit with...
