DV output doesn't seem quite right.

Hi,
I don't know why or what I am doing wrong but it seems that when I view my file that was rendered in CS4 (basic DV file 720x480 29.97) and reimport the clip into my editing program (Grass Valley Edius), the footage does not seem to be as pristine as the original DV footage. There is a "film like" look to the frame rate and there also appears to be a cut in overall resolution. I have all output settings to "best" and I tried playing with field, upper and lower, but no combination seems quite right. I know this program can handle a wide variety of formats so I can't believe that simple DV should be a challenge.  As an FYI, to eliminate all variables, I didnt apply any effects to the footage, just inserted a clip into the composition, and rendered it out.
Any ideas how I can get my DV footage to look exactly like the original?

As a follow up to my prior post, I did find a way in Canopus to convert the original DV file to an uncompressed RGB. I took the uncompressed file into AE, and then output as PNG sequence. Still, the results are not as good as the original DV footage. Incredibly disappointing. I am surprised that you don't hear more people complaining about this since I am sure DV is still widely used.
I think you have a fundamental misunderstanding of DV as a compressed format - it can never look as good as the original. DV uses a very agressive compression that reduces color information and produces a lot of very visible artifacts. Whenever you compress it again, you apply another level of degeneration on top of the existing one. You can't have both - either you don't modify the source footage and allow the programs to work in bypass, re-using the original stream data or you modify the image content, based on the decompressed and reconstructed info, but in turn enforcing a completely new compression pass.

  • ALIAS email account doesn't work quite right

    Is there anyway to make this iPhone email app work just like it does on the computer with the Alaises?
    I set up my Alias email name as a separate account within the Email settings, so that if I am on the road, I could still make it work like I do with my regular Mail account on the computer or webmail at .Mac -
    but it doesn't work.
    If click on the Alias account as it shows, it ends up sending the email from my main account name and does not distinguish it like it does on my computer.
    This is a problem for me, as I use 4 aliases, just to differentiate my work focuses. The Mail app in the iPhone should do exactly what the computer does, but it sends everything out as my real account name.
    Any fixes???
    Thank you!

    I have three separate email accounts set up on my phone. They are all three POP3 accounts. My main account, my work account, and my student account. My work and student account outgoing servers do not allow for relaying, so I have to use something else to send them from. I use my main ISP outgoing server for that because it has authentication. In the setup for my work and student accounts on the phone, the information entered has my work email address on the one, and my student address on the other. When I send mail from either of those accounts, it shows as being from those accounts. Even replies to mail I receive there shows as being from those accounts. I can't speak about IMAP accounts, not the .Mac. I did set the accounts up directly on the phone, not by syncing them from my computer.
    Hope this information is of some help for you.

    Quite right, but as the OP does not have component or composite connections not important.
    To the OP, this does work, but is not the cheapest, and as it appears that Apple no longer sell an SVideo adaptor cable 3rd party it will have to be.

  • X-Fi DD-DTS doesn't seem to work right playing DVD Movies with VLC Player or anything els

    I have an X-Fi Platinum with the bay and When I try to Play a DVD with VLC Player And choose a/52 over s/pdif it sounds HORRID skipping and pausing and not functioning at all.. I must choose 5. channel to have Listenable Audio. The Same goes for AC3 Encoded Files If I chose A/52 over S/PDIF in VLC player it sounds like **bleep** and doesn't seem to decode it right. I must chose stereo 2 channel to listen to AC3 encoded video's.. NOTE The dolby Digital symbol DOES appear when i chose A/52 over S/PDIF so it does know it's a digital signal.. And I have the software set to USE hardware decoder and S/PDIF in Decode selected. NOW Here's something that REALLY makes me wonder wtf is wrong, I can connect my Home DVD Player or Cable Box over the Optical?in OR the S/PDIF in and the SOB works Fine, The Dolby Digital symbol comes up and everything sounds great! I get Dolby Digital surround no problem..Why in the heck does it not want to play DVD's using the A/52 over S/PDIF or any AC3 Encoded Files?What's the deal?And I am using windows XP Pro SP2 yadda yadda yadda?Message Edited by mbrown0420 on 07-25-20070:58 PM

  • Back from service, case doesn't seem right

    I just got my macbook pro back from service, maybe a week or two ago. Since its been back I've noticed the case really doesn't seem like its fitting together right. I've got gaps between various pieces of the case and have parts that don't really fit flush anymore. It wasn't like this when I sent it out
    If I call apple do you think they'll fix it? They could easily just ignore it and blame it on me, but it definitely wasn't like this when I sent it off, and the more I look at it the more it really seems put together wrong.

    I'm guessing that there is a gap on the front of the machine where the bottom case fits with the top case (the part with the keyboard & trackpad).
    Once the unit is popped open, it doesn't close quite like it did when it was first assembled. That's because there are 4 clips that are on the front inside lip that get slightly worn when the machine is popped open. I'm also guessing that there is a glue of somesort that is run lightly around the seams to ensure flush enclosure.
    There are stories that even without servicing that these gaps form after time.
    If you go and demand that apple fix it, they will. They will have to replace the top and bottom case. This fix could take quite a bit longer as it would need to be sent out to the depot. All of the innerds need to come out to replace the bottom case. But...they'll do it if you demand it.

  • Something doesn't seem right with start-up

    Maybe I'm going mad but something doesn't seem right. When I start-up I get the usual chime, the power light comes on, I hear the drive whir a bit, the fans have a quick blow and the I get a black screen for about 30 seconds. After this the light goes out & the screen turns grey, then I get the grey sceen + apple and the 'wheel thing' followed by the blue screen and normal start-up. Perhaps this is normal, but I'm sure I never used to get the 30 second delay with the black screen and I used to go straight to grey if you see what I mean. Am I going mad or is the delay unusual??
    Neil

    I know it's bad form to reply to your own post but thought someone might be interested to hear how I've sorted this one out. Thought I'd try starting up in safe mode and running FSCK, but having never done this before wasn't quite sure what to expect! When it started up I just got page after page of 'techno-jargon' which didn't look good - especially when every line seem to have the word error in it - can't remember exactly what it said but each line had something with USB along with numbers and letters and an error message (yes - I know this isn't very clear but the memory's beginning to fail). Anyway because this wasn't looking too good I decided to reboot and unplug everything from my USB ports (including a 7 port USB 2 hub) and restart. Lo and behold problem sorted. Then plugged it back in again and tried again - back to original problem. However noticed that the LED on my graphics tablet wasn't lighting up so unplugged that from the hub, reinstalled the drivers and tried again. Now everything seems to be back to normal. The black screen on start-up lasts just a couple of seconds and we're back to the normal start-up time. Weird, but at least I can now sleep easy!

    Hi I'm running Addressbook and cannot clear previous entry easily when searching my data base of around 5,000 contacts. 
    I prefer to view in All contacts on a double page spread with details on the right page.  Searching doesn't seem to work correctly in this view.
    It's always the second search that is problematic.
    I've tried typing over and all it seems to do is confine the search to the the entries that have come up for the previous search.
    I've tried to use the x to clear the previous entry and then type the next search, same problem.  The only way seems to be to move from "All Contacts" to "Groups".  Then the searched name appears and I can return to All Contacts to see full details.
    Surely three key press' are not the way it's supposed to work?

  • SSD Cache in HP ENVY Phoenix 800-445qe doesn't seem to be installed right

    I have a newly purchased HP ENVY Phoenix 800-445qe which includes what's supposed to be a 16gb ssd cache.  Running WIndows 7 Pro 64.  
    The ssd drive was factory installed so it shows in Windows as with the name DATADRIVE1 (doesn't sound like it was intended as a cache, does it?) and it shows as drive E:. My understanding is that if it were really installed as a cache, it wouldn't be showing as a drive in Windows Explorer.
    The HDD was set as ACHI in BIOS, not RAID.  The Intel RST screen in firmware (accessable through Ctrl-I) shows both drives as non-RAID Disks.  The HP support assistant shows the Intel RST x 64 driver v 13.2.0.1016 installed. 
    Elsewhere on the HP site is a support article with the title: A Seondary 16 GB Drive Shows up in Windows 8 File Explorer, which is the problem I'm having except, I have Win 7, not 8; it says to download a softpaq with release notes that say it only applies to HP ENVY HP-8 systems and requires Win 8; it's fix is to install Condusiv ExpressCache, which I'm under the impression is an alternative to Intel's RST, not something that works with it.  So that doesn't seem to be the fix I'm looking for.  HP Tech Support's helpful suggestion was to find a local computer dealer an pay them to fix it. (Yeah, right.)
    Does anybody here know how to get this thing working?

    There ain't no such thing in the Control Panel.  *sigh*  
    Let me jump off in a very different direction, because as this point I've probably wasted more time on this than the cache can ever save me over the life of the system....
    I have a 128GB SSD on order that I was going to install as my data drive, and then keep it backed up on a partition on the HDD.  That's almost twice as large as my OS+Programs partition on my current XP machine.  I'm thinking maybe I should bail on the whole cache thing, install the 128GB drive as my OS+Programs drive, and set up the 16 GBs as a data drive (since it seems to be set up that way already anyway.  That's a little small, but I can make it work if I move older data files to the HDD as a kind of near line storage.
    Unless you know of a reason I can't do that--like the mSATA SSD won't work as a drive--the question then becomes, how do I set up the 128GB SSD as the OS drive?  I see two possibilities:
    The first would be to use the HP restore image function to initialize the SSD, so it has the EFI partition with the Boot information, and then use Norton Ghost to restore the Ghost image I've created from my now customized Drive C (removing bloatware etc) to the new SSD.  
    The second--which could be a lot easier-- would be to make a ghost image of the entire drive of the current HDD and then use Ghost to restore the image to the 128GB SSD. 
    Do you know if either or both of these approaches will work?

  • Email Security Plug-in - Doesn't seem to work with right click or save and send

    I've searched the knowledge base but have not located the answer yet.
    We have the Encrypt Message plug-in installed to flag the email [SEND SECURE].  This works very well when in Outlook.  It does not seem to work when right clicking a file to send outside of Outlook or performing Save and Send from within Microsoft Office.  The add-in still shows and users are clicking it and the Send button but the emails are not going securely.  We are on Microsoft2010 on mostly XP machines.
    How can I get Encrypt Message to work in all instances?
    Thank you.

  • Safari on my iPhone 6 running 8.02 doesn't seem to work right. Some Java scripts don't show correctly and they do on other browsers I have downloaded. I tried almost everything and nothing seems to work to fix it. Please help.

    Some websites like the one of my college uses JavaScripts and they seem to load correctly to a certain point but then not really. For example in one it would say select an option from the left menu. And I do it hut nothing happens. But when I go to the same website in another browser on my phone. The JavaScript works completely and allows me to see whatever I was clickig on that menu. I have seen that there are other websites being affected too. I tried clearing my cookies and data. even restarted my phone. And doesn't seem to work. I don't know how change the configuration any more to make it work like normal. At first I thought it was my school's website but it never got fixed. And now I realized is my safari browser! I wanna keep using it since I am really familiar with It. If someone knows how to fix this please let me know!
