the firewire output is still full res, so any transfers to digibeta or whatever shouldn't have suffered.

You are sure right but the"silly" cam could not record back from the MAC so the optoions left (for now) was the lo-res stuff. However, I have now "cut" the stuff directly from the cam and transfer the clips as is to teh server.

Really nice these EU tax rules that damages (cripples) many of the lower price range DV cams from re-recording the edited files? "I am the Taxman" - TAXMAN - Fab Four 1966! Yeah I know they can be hacked but I just borrow this one.

Actually saw a new Panasonic miniDV today that could re-record the files via FW for about 900 Euro. Technically tempted but again this silly stuff do not allow to input analog video so I can not transfer my Hi8 stuff via the cam to the MAC via FW. Silly BRATsBERG! EU!!

no, you misunderstood. even the low resolution clips you posted have the full quality data in the file, it just doesn't display on the computer, so when cheezy transferred you "low res clips" to digibeta he did in fact get the full resolution.

*there's nothing wrong with you clips*, so you can stop trying to solve a problem that doesn't exist. the only problem is that when you play a dv file on a computer, it displays it in lower quality for performance reasons. when you output such a file to tape, edit it, convert it to mpeg or whatever, the full quality version is used. try exporting a still from one of those low quality clips and compare it to what quicktime player displays. you should see a huge difference...

hi res dv

Well, they look much better now.
QT won't play full screen and for some reason is flashing purple again in Premiere. Using the Panasonic DV codec and exporting to avi they play full screen and look better than Hi-8.
Very nice.
More?

Not disputing your say Mattias. Just anxious how to recover the 50% size/quality drop from the original cam DV files to the files I posted but if the "testers" who downloads the files can recover it I will be very happy about that.

Just to be on the safe side I post the original 100% DV cam files as well.

The thing I discovered was:
When I edited the cam files in iMovie the file sizes dropped by 50% as did the image quality (on the MAC in QTPP).

On the other side when I converted the "raw" DVcam files to real uncompressed quicktime clips I saw something like 200% image improvement from the raw files at playback and I could dammit see the film "texture" and the grain dropped severely looking much better than when I playback the raw files on the QTPP on the MAC. I guess that the DSP in the cams does this job normally at playback?

68 mb/s proved a little tough at cam panning or moving objects but the MAC managed that quite well still. A RAID thing would done it though. 12 fps at this data rate is no problem and the image quality is stunning.

Anyway, as said I will post the raw files just to offer it all since I have no cam to record back to to double check the quality that way.

Maybe I have to stick with the "old boys team" running film through the projector only? Getting too old for this. Me wonder?

Thanks for the new clips! I will give them a "twist" tomorrow :wink:
And my colorist friend will be happy to know the clips I showed him were only half-res clips... :lol:

Err... Not exactly... Because I imported the files in Media100 at 360kb 2:1 compression (we didn't upgrade to lossless yet...) That was my only way of feeding an sdi signal to the digibeta.
But I get your point :wink: that is they were not low-res when I imported them...

Booster, the new clips are absolutely the same. The thing that actually shocks me is the way the overexposed skies react. The grain is really odd in these parts. Anyway, I always found the Canon 1014 XL quite grainy, even on K40. So these new films probably don't help much...

they can, if they have the right software. in quicktime pro, and perhaps the regular qt player: go to the menu->movie->get movie properties->video track (left drop down)->high quality (right drop down)->check the "high quality enabled" box->done. other players/codecs should have a similar setting somewhere.

converting to another format will also "bring back" the high quality, as you noticed when you converted to uncompressed, and cheezy when he converted to media 100 (sorry for assuming too much before).

Hmm.. very strange. My C1014XL-S cam produces very grain free (I would say totally grain free) takes on K40.

However, the bright skies on the negative PRO8mm films always (only partially) turned out grainy (whatever the film speed possibly except the 500) like as if the exposure was too dense for the transfer system used as matt inidcated on the grainy 500T footage shown previously.

The side by side shots on 50D and K40 is totally grain free with the K40 so I hope the WorksPrinter transfer copes with this.

The most problematic light situation with the negs were when light tended to be directed into the camera at a more or less direct angle. This always produced "anbormal" grain but I believe, less with the 500.

Anyway, you now have the highest res quality V200T clips I have available of this film stock. The only detail that are not verified is if it was exposed at 160 or 200 ASA. Normally the auto notching system sets it at 160 ASA but there are a 200 ASA setting available which I do not know if my cam has, I think it does.

If not correctly set it is set at 160 ASA which may possibly influence on the grain structure, I do not know for now.
