History of NLE

Hey folks,
I've taken advantage of the current economic downturn/meltdown (delete where applicable) to go back to school and do some postgrad work. (Loving it, can't say I miss the world of "real" work.)
I'm interested in the history of non-linear editing in general, and wondered if any of you - especially the old-timers - can point me in the direction of some good histories, websites, books etc. (And before the elitists charge in, may I say that this is to supplement my own research, not to kick-start it.)
If anyone here has worked on early NLEs (e.g. CMX 600, EditDroid, or Harry), I'd love to get some anecdotes about your experiences. (I know Harry was a compositing system, but it did have some NLE capabilities, or so I'm told. My own experience with Quantel started with PaintBox, then Henry, so I don't know Harry personally).
Thanks in advance,
Denis

Denis - NLE is the process of separating scenes, saving them in bins, then selecting and joining them into a shot sequence, with the ability to rearrange their order ( if wanted) . . . spreading apart, adding in new shots at any point, etc. This is the film editing process and is the work flow that digital NLE has emulated. In order to be non-destructive, film editing is performed with work-print footage, an exact duplicate of the original film coded to match the original film then edited. Following the completion of the work print edit the original film is conformed to the edited work-print for final processing (IP, CRI, etc.) for printing. Further 35mm film, when necessary, is physically cut and spliced between frames without any frames lost or destruction. Also it can be optically printed to an intermediate film stock (following the work print edit) without ever being cut. It is the same work flow as digital video NLE.
Conversely, tape-to-tape editing is analog linear editing . . . one scene after another with no ability to insert shots within the edited sequence without dubbing off any already edited scenes following the insert point then bringing this back to the edit with its generational loss.
Hope that this helps.

  • Package H.264 as ISMV or ISML (via MFCreateFMPEG4MediaSink?)

    Hi all,
    I have an application that outputs content (dynamically generated with Direct3D) to mp4 via Media Foundation. This code has been working well, and now I'm looking for a way to stream that content with as little latency as possible to a Smooth Streaming publish
    point (Azure Media Services in this case). I've successfully created video-only fragmented MP4 files with MFCreateFMPEG4MediaSink and IMFSinkWriter, but I can't find a way to create f-MP4 files that are compatible with the Smooth Streaming Protocol.
    The files I can currently output have a ftyp indicating a major brand of "mp42" and compatible brands of "mp41" and "isom". For smooth streaming, this needs to be "isml" with compatible brands "piff" and
    "iso2". Also, it looks like every frame is a keyframe, whereas Azure expects key frames every 2 seconds. This may be because the encoder is generating a file where MF_MT_MPEG2_PROFILE is set to the H.264 Simple profile-- and I can't get it to produce
    anything else. I tried setting the Main profile on the media type I pass to MFCreateFMPEGMediaSink, but it doesn't seem to affect the file output:
    hr = mediaTypeOut->SetUINT32(MF_MT_MPEG2_PROFILE, eAVEncH264VProfile_Main);
    Again, setting this or any other profile doesn't seem to have any effect on the output.
    I believe the actual H.264 output is correct (and of course the fragmented mp4 video files do play back properly), but need to ensure it is packaged properly. Is there any way to do this with Media Foundation?

    Looking back over the development of and the popularity of H.264 and comparing that against the history of NLE product releases, I see that FCP is way behind the curve. Who knows why? The current version of Adobe's suite benefits from many years of FCP's history of failing to meet the needs of a certain niche of users. Perhaps the decision to put all development energy into FCPX at the expense of adding advanced codec handling functions to FCP7? It's a bummer for lots of us that FCP7 came up so short and has now been effectively killed.
    Only time will tell if people like you and me will switch to acquire functions we need now or adopt the new paradigm and see if things evolve.

  • H.264 Container / Edit

    Hi All -
    I realise this question's been asked many times before, but it appears from all my searching most of these questions were posted some time in the past - so an update may have occured to the package since then, or a new workflow invented which makes what I'm trying to do possible.
    How does one NATIVELY import and edit H.264's without needing to transcode via Compressor first?
    I have quite literally hundreds of files in HD H264 that I want to use as source, and I really don't want to have to transcode the lot of them.
    I realise FC isn't happy working natively with H264's, but since this appears to be an issue that crops up so often I was hoping somebody out there had found a workaround either via process or via a plugin.

  • How do I stop FF from restoring previous session, I've already played with all the options I can find but nothing stops it unless I delete history each time.

    Recently, FF has started opening my last tabs when I start a fresh session. I have already checked to make sure that none of the applicable settings are enabled, such as under Options->General: When FF starts "SHOW MY HOMEPAGE" is selected. But for some reason, it opens my last session. The only way I've been able to get it to stop doing this is by having it delete my browsing history after I close the session. I don't want this since I often use my history to re-find information I need for class research. I have made certain that all my settings are the same from before FF started doing this. It only started doing this after the computer was turned off for a long weekend.
    I've already searched through the Mozilla help pages and all I can find is how to restore the previous session or similar. I don't want to restore my previous session, I want it to stop restoring my previous session without having to delete my browsing history each time.

    Using the instructions here:
    http://kb.mozillazine.org/Session_Restore#Disabling_crash_recovery
    I was able to turn off that feature entirely without having to create a new profile.

  • I can't print anymore, the "help" button doesn't work, and Firefox always sets to "Never Remember History" even if I change it

    SO many issues with Firefox now! For one, it crashes quite a bit. I submit the crash report, and go from there. Keeps happening. But the main thing is this:
    I go to "Options" and under "Privacy" it has "Never remember history" - I change it to "use custom settings for history", hit "ok" and then when I go back to it, it's back on "never remember history" already. What gives?
    The issues I'm having right now is that I used to click on Print in my email (Yahoo) and pop-up blocker would stop it, but a dialog would pop up saying "try again", and I would hit that, and a separate window would open where I could print the email. Now, when I click on print, NOTHING happens. No box, no changes whatsoever. No pop-ups blocked, nothing at all. I mean, the button for "print" doesn't even react like I clicked on it. Nothing happens.
    The other issue is that when there's a text box, if I start to type my email address, it suggests my email address. It never used to do this! I don't want this, either. How can I stop the suggesting of my email address. I don't want it to remember what I typed!
    Another issue with Firefox is that when I click on the "menu" button in the top right, there's a question mark that says "open help menu" at the bottom. When I click on that, the help menu is EMPTY. I included a picture so you can see.
    I've "reloaded Firefox", as well as downloaded another copy and actually reinstalled it. All these errors keep happening. How can I get them to stop or function correctly? What's causing them to work all wonky?

    The "Use custom settings for history" selection allows to see the current history and cookie settings, but selecting this doesn't make any changes to history and cookie settings.
    Firefox shows "Use custom settings for history" as an indication that at least one of the history and cookie settings is not the default to make you aware that changes were made.
    If all History settings are default then the custom settings are hidden and you see "Firefox will: (Never) Remember History".
    "Never Remember History" means that Private Browsing is active and "Always use private browsing mode" gets a checkmark.
    You need to remove the checkmark on "Always use private browsing mode" to leave Private Browsing mode or chose the "Remember History" setting.

  • How can I make sure my history doesn't expire and that I can transfer over places.sqlite?

    There's probably alot of questions on this subject asked already but I've gone over just about all of the possibly relevant ones that've been already asked and I still can't figure out what to do. I'm trying to move my complete history from an XP Firefox profile over to a Windows 7 profile on another computer. Do I just do it by copying the places.sqlite file within that XP profile over into my USB flash drive, then replacing the places.sqlite in the Winodws 7 profile with the one from the other one? And after the file's in the right profile will I be able to just view all the sites I viewed on the old computer on the new one's history dialog box? I only am transferring my XP history to my Windows 7 because I want to look at stuff several months back and it keeps expiring on me, even to the point of getting rid of a month of history a week or so ago. This brings me to my other point, I keep up fairly well with updating both of my Firefoxes but recently (and I think this was way, way after they updated the browser so the history isn't set to expire by days anymore) the history just isn't reliable anymore. My XP will not only expire older months of history faster and faster it seems, but individual websites at the end of each month will actually disappear as I view new ones, instead of it all staying in there and just expiring each old month as a whole. Also, random sites in every month scattered all over the list of URLs will just disappear, and random sites that I've only visited in the past couple days will insert themselves randomly into much older months of history, which makes it hard to figure out the URLs I've seen, this last one seems like a common problem from what I've read, and all of these problems seem to be slowly creeping into my Windows 7 as well when they were originally on only my XP. The thing is for a very long time my Windows 7 would keep every ounce of my history that I kept on it, unless of course I went through the Clear History process myself. Now it seems to be slowly deleting it and having all the other problems that I mentioned earlier. I've got 592 GB out of 931 GB that's free space on my Windows 7 that I want to transfer my XP history into, and my Control Panel System panel says I've got 8 gbs of RAM in total. If I need to get some other information on RAM mention how to do that if you could. So in total, how can I transfer my XP history over into my Windows 7 so I can view all the sites I viewed on my XP in my Windows 7 history panel, as well as view all the old expired and/or manually deleted history on my Windows 7, without worrying about whether it will expire itself while I'm viewing it and writing down the relevant URLs that I need to know about. If I can only keep all my history through installing an add-on, a link to a relevant legal add-on that'll work well on both operating systems would be appreciated. Thanks to all here. (:

    Hello Saethwyr99,
    ''Do I just do it by copying the places.sqlite file within that XP profile over into my USB flash drive, then replacing the places.sqlite in the Winodws 7 profile with the one from the other one?''
    you are correct : [https://support.mozilla.org/en-US/kb/Recovering%20important%20data%20from%20an%20old%20profile#w_your-important-data-and-their-files Your important data and their files]
    ''Also, random sites in every month scattered all over the list of URLs will just disappear, and random sites that I've only visited in the past couple days will insert themselves randomly into much older months of history, which makes it hard to figure out the URLs I've seen, this last one seems like a common problem from what I've read, and all of these problems seem to be slowly creeping into my Windows 7 as well when they were originally on only my XP.''
    from Firefox 4 and above versions there is not a time limit for the history.
    Firefox determines automatically how many pages can be kept '''without affecting the performance.'''
    ''as well as view all the old expired and/or manually deleted history on my Windows 7''
    i think this in not possible
    ''If I can only keep all my history through installing an add-on, a link to a relevant legal add-on that'll work well on both operating systems would be appreciated.''
    check the next add-on : [https://addons.mozilla.org/en-us/firefox/addon/expire-history-by-days/ Expire history by days]
    thank you

  • How to handle BP who is both Customer and Vendor during history import?

    Hi Forum,
    This is for importing Financial transactions for Open Sales Orders, Open Sales Invoices, Open Purchase Orders and Open Purchase Invoices and also for importing history for all Closed Sales Orders, Invoices, Purchase Orders and Invoices.
    Our prospect has in their current system Business Partners who are both Customers and Suppliers (Vendors). In SAP Business ONE, BP is unique. It is recommended I believe in situation where BP is both Customer and Vendor, we need to create two BP Ids.
    Question?
    How do we import open and history of invoices in this situation where the same BP is both Customer and Vendor? Any tips would help please.
    Thank you all very much.

    Hi Syed,
    As Gordon and Rahul said, it is painful for you if you import closed transactions.
    Try to compromise your client that to use the old system for last year/old reports.
    Its always good practice to import the Opening balance and even the open documents only.
    If you have partially open items, then import the document for open quantities only.
    Let's say, if you have a sale order with an item of 100 Qty. Among that 100 qty, lets 20 qty has been already delivered then you have to create the sale order in SAP for remaining 80 qty only.
    Regards,
    Bala

  • Invoice payment history report

    I'm looking for a report that will show me the payment history (open items and cleared items) that corresponds to an invoice or a list of invoices. I have played around with a couple of standard SAP reports and I don't find them to be all that pretty or easy to use.
    Does anyone have a custom report that they've built to gather this information and would be willing to share? Or, even better yet, does anyone know of an SAP function module or report that gives this information in a reasonably nice format?
    I am looking for detailed information on each payment if possible.
    Thank you,
    Andy

    Naimesh, thank you for the quick reply. I have checked out that transaction and it is a good start for me. I'm hoping someone might have located or created a report that is more specific to this particular function that I am thinking of.
    If not, this will work well as a starting point.
    Regards,
    Andy

  • Print History Report on HP Officepro 8500A Plus

    Can I obtain a print history from the printer similiar to a fax history?

    There is not a print history capability available from the printer.  The total page count is available from a self test page.
    Depending on your operating system there may be third party applications that can track printer usage.

  • After upgrading to Firefox 11.0, clicks that link to a file do not report in the history and do not show up as visited.

    Installed Beta 12.0 to no resolution. This same issue is happening on my other computer running 11.0. Checked in MS Explorer and links work normally.
    Here's an example link:
    file:///Z:/shared_cvo_docs/cust_inventory.xlsx
    This link opens a excel spreadsheet file from my system. I have many of these types of links and I find it very helpful when I use the browser to open these as I can see which ones I've already opened. Without the links changing color, this becomes very difficult.
    Running Win 7 Ultimate
    Thanks for your help!

    My history shows local .html files displayed in the browser, but not local files handed off to an external program. Is that the pattern you see as well?
    No idea whether this was an intentional change (I don't see it on the Firefox 11 change list: [http://www.mozilla.org/en-US/firefox/11.0/releasenotes/buglist.html].)

  • How can I display ONLY bookmarks, and not History?

    I'm sorry to ask a question with probably such an obvious answer, but I have never been able to figure this out. I want to display all my bookmarks so I can do a search & find the right page. But I always get my entire list of every page I've ever visited. I don't want to delete my history, but I want to only show real bookmarked pages.
    Here's what I've been doing: I select "Show ALl Bookmarks." Then I select a folder on the left under the header "BOOKMARKS." It still shows all the pages I've visited today.
    Thanks.

    After you enter the search criteria make sure you click on Bookmark Menu in the upper left of the coverflow window.

  • IChat - Synching Chatting History from multiple devices on same account

    I currently have the iChat server up and running on a MacMini running OS X 10.6.4. I see in the iChat client on my MacBook Pro where it will load past messages when I open a chat with a buddy. I am also running a jabber client on my iPhone (IM+ is the iPhone app). What I am curious about is if there is a way to load chat history for the account, not just from the device.
    For instance, when using Skype the following will occur. I can chat on my iPhone, and then when I login to my Laptop, the history of chats sent from my iPhone will be added to the history on my Laptop. I am trying to prevent having to look back at every device I use my jabber account on to find that one IM message that has the information I need.
    Is there a way to sync the account on all clients (or at least just my MacBook Pro) so I can view chats there sent from all my devices and not just from my Laptop?

    Tim,
    I have turned on the logging feature inside of the iChat server, and I have seen all IMs being sent are saved.
    So do you think this is more of a client side problem of not being able to sync from the Message Archive on the OS X Snow Leopard 10.64 iChat server? Meaning that if the IMs are being saved, then all that really needs to be done is to create a client that will access the server log and do a compare of its local saved history with the server saved history and then takes any missing IMs and adds to its local history log?
    Am I far off base on this, or does this seem feasable?

  • Is it possible to view your current history for a single tab in safari lion

    Is it possible to view your current history for a single tab in safari lion?

    Not once the tab has been closed. If it hasn't, clicking and holding the Back button will display the titles of recently visited sites in that tab.

  • HT1632 I can view a workout on my ipod touch history, but not in itunes or on nike+ website.  I can't seem to upload this run and it's really annoying as I'm loosing about 12k of runs.  It seems to happen when I program in a custom run.  Can you help?

    Hi there,
    I have just done a custom run on my Ipod touch 2nd Gen of 12k.  When I finished the run is appearing in my run history on my iPod touch, however it is not appearing in my itunes 'Nike+' tab, or on the Nike + website.  I can't seem to get this run to sync and it is really annoying because I'll be loosing 12k.  Can anyone help or has experienced this before?  I know there are solutions to add runs to iPod nano's and older iPods using the 'Enable disk' and iPod_control function however from what I'm aware you cannot do this on an iPod touch.  Can anyone please help?
    Many thanks

    You should really read the manual.
    "How do you restore from backup? "
    Restore.  When given the choice, choose to use backup.
    "And how can I check to see if the pics and videos are on my computer somewhere first??"
    They would only be where you put them.  What program did you use to import them?  Pics/vids taken with ipod are not part of the sync process at all.  You should be importing them just as you would with any digital camera.
    If you did not import them, then they are not on your computer.
