#JPEG vs TGA
10 messages in this thread
How do JEPGs compare to TGAs when ready to drop final online, broadcast quality
frames?
I love the compression, but will the final product suffer?
Thanks.
That depends on how much compression you're using in JPEG. The default
which is technically lossless not much on an EVO. If you look close
you might see some scintalating depending on how busy your materials
are. But with blur it probably will not be noticeable. On bigger
projects with higher budgets I wouldn't risk it, but for a few flying
logos etc. its your secret. <g>
Thanks. That's what i was thinking. I've been using JPEGs for offlines on my
EVO-9650, but it's time for the PVW online and I didn't want to risk it. Too
bad, the space requirement even at JPEG (100) is refreshing!
Another EVO user, hello, hello. <g> Gus has a new driver for it, if
you're interested in the ability to do single frame insert edits on
pre-recorded animations. It should be up-loaded shortly. I know what
you mean about the JPEG. I'm sure it compares favorably with the PAR.
But I can't risk it either.
Are you interested at all in sharing tips regarding DNR status, tape type, etc.
in an effort to globally improve our results?

Certainly, DNR is useful for playback and has a feature which allows
you to see field recorded images as a still. I haven't found the best
tape but Maxell is reported to be the most drop-out free. I've had
difficulty getting it to test. David Marks is also quite
knowledgeable about EVO's and I'm sure he'd also be happy to answer
your questions. Between the two of us we should be able to cover a
good broad range of EVO related questions. On the technical
programming side Gus Grubba knows the ADI interface, so I think
you'll find you're pretty well covered. Anything you'd like to add is
also most appreciated.
>> I'm sure he'd also be happy to answer your questions.
Certainly. We use Sony tapes and they are fairly decent. I've heard the same
praise about Maxell tapes. [ Christopher, ] always use MP tapes, never ME;
stick to 30 minute tapes and avoid recording on the first few minutes of the
tape. Space your recorded segments a few minutes apart. Always rewind the
tape to the beginning before ejecting it.
David,
>> We use Sony tape …. << So do I, though I get more drop-out than I'd like.
You did that well, I wasn't sure what he was asking and you gave a good general
rundown on the important things, which I take for granted. I'd like to try to
get some of the Maxell. Maybe I'll order a case. Can't get individual tapes to
test.

You might try a video vendor here in Connecticut named HB Communications. I
imagine they would ship outside of New England. Numbers I have are
(203)234-9246, FAX (203)234-2013, (800)922-2776 (in CT), (800)243-4414 (in
N.E.)
I believe that they sell small quantities, as well as boxes, cases, crates,
truckloads, etc. <g>

I might do that, many of the local dub houses get tape from out of town. Wierd
in a city this size.
Thanks,
