Vegas compiling on a notebook computer

    I recently brought a fast i7 processor notebook computer.
    What I want to do is to edit my videos on my desktop computer that has a
    large monitor then compile the video on my notebook computer as it has a
    faster processor.

    My problem is that when loading the video files on my notebook computer
    which consists of a C drive is that if they were originally edited when
    located on a drive on the desktop computer then I need to tell Vegas where
    the new location is for the files each time I had made changes and want to
    compile the video.
    The other alternative is to put the video files on a external hard drive
    and have Vegas access the files via USB 3.0 when it compiles the video. I
    still have the problem of the external hard drive appearing as drive H on
    the desktop and appearing as drive D on the notebook computer.

    The notebook computer has a hard drive that rotates at 5400 rpm and not the
    recommended 7200 rpm, would this cause a problem when rendering a video
    using Vegas?

  2. As I understand it, notebook CPUs are about half as fast
    as desktop CPUs (with the same "names") with software that
    can use multiple CPU threads since they tend to have half
    the available processing threads (an i7 notebook has four,
    an i7 desktop has eight; both have four cores). Also, even
    with a much slower CPU in it, with a suitable "fancy"
    many-cored GPU in the video card in it, the desktop would
    render video MUCH faster than would any notebook. In Vegas,
    you can tell the software to use either the computer's
    CPU or the video card's GPU to render video....
    How about networking the computers, so your source drive
    remains the same on both computers?
    No. Since the read speed of that hard drive would be far
    faster than the render speed of the CPU, that should not
    be a problem.

    They talk of "network rendering" here. Your laptop would be
    a render server, the desktop the main editing station. I have no
    idea what the licensing is like for this (one license per machine,
    or network render machine covered by same license as editing machine ?).

    http://www.emedialive.com/Articles/ReadArticle.aspx?ArticleID=11105

    You'd need a good network connection for this, between machines.
    Not a job for a 100BT switch and 100BT on each PC. More a job
    for GbE switch and GbE networking cards. The new laptop is
    likely all ready to go for this (GbE built-in). My laptop has
    GbE. Not all my desktops do. My second best PC is only 100BT,
    and I fitted a PCI NIC card to get GbE (gigabit Ethernet,
    about 117MB/sec best case).

    On the hard drive aspect, a 5400 RPM drive, that affects the
    seek time (average impact is one half the rotational latency).
    But on sustained bandwidth, the 5400 RPM drive does pretty
    well, and can be closer than you think, to the 7200 RPM drive.

    I have nothing but 7200 RPM drives here, and the best transfer
    on the old ones might be 60MB/sec. Whereas the newest drive
    is around 135MB/sec. So the generational aspect of hard drives,
    has an effect on the sustained number.

    Have you considered plugging an external monitor into your laptop?

  5. If you assign the drive letter H: to the USB when you plug it into the
    laptop, it will always be H: when you plug it in again later (unless
    some other drives get plugged in in the interim, which could have an
    effect).

    The laptop has a HDMI connection as well as the older monitor connection so
    I can connect the laptop to my television to view a video in LCD. The
    problem with laptops is that they have limited Hard disk space (750 GB in
    my case) not like having several 2TB drives in a desktop computer so I'm
    trying to limit what I have on the hard drive. The only other way is to use
    external hard drives. I have a spare monitor but its not wide screen.
    However the laptop does offer 1080p when connected to an external monitor
    so worth worth considering later.
    The current screen is 15.3 inch which is OK when I'm close to the screen.

    Thanks Gene. That would certainly help solve the problem.
    At the moment I'm trying to learn Windows 8 as it came with the laptop. I'm
    hoping to find out how to assign letters to drives in Windows 8.

    Thanks for the info David.
    Its interesting to know about threats.
    I don't now much about networking computers but will try to learn more.
    At this stage I just want the laptop to be a work horse to take the load
    off my Desktop computer so I can use it for other tasks.

    One problem I did find when I was feeding analog video to the usb port of
    the notebook (when copying a VHS tape) is that its dropping frames. I
    suspect that I'll need to turn off The Norton's Antivirus which was
    installed when I brought the computer. Copying VHS tapes was another job I
    had for the notebook computer.

  10. Same as in Windows 7 and earlier versions.

    Things may have changed as my laptop has a Intel Core i7-4700MQ processor
    (released in April 2013)
    It has 4 cores and 8 threads.
    The clock speed is 2.4 MHz with a max turbo frequency of 3.4 MHz.

  12. Thanks for the information; I value having good
    information more than "being right"...;-)

    I am now considering using my notebook for video editing as it has a more
    powerful processor. I tried playing back a video in Vegas that was on the
    timeline and it played back smoothly in full screen in the highest quality.
    The main limit is that hard drives are smaller in capacity on laptops, mine
    is 750 Gigabytes but I could always plug in a external hard drive.

  14. It is possible to replace the internal drive in many laptops, but you
    definitely need a robust way to transfer the old system to the new
    drive.

    Having said that, I still suspect that an external drive is a better
    solution, if you don't mind having an extra box to carry (and 2.5"
    external drives are compact and lightweight).

    If you have a USB3 port on your laptop, you'll be much happier with a
    USB3 drive (or at least I am).

    Windows 8 has some useful features and one of them is a system image backup
    which is useful if replacing the hard drive of the notebook computer. It
    will create an image on an external hard drive. There is also a file
    history feature to copy all the computers files and restore them in the
    original location if needed using an external hard drive.

    External hard drives are dropping in price so it might be worth while
    buying a 1GB portable usb 3.0 external hard drive to be used for video
    editing only.

    The notebook has two USB 3.0 ports and one USB 2.0 port.
    What surprised me is that an external blu-ray drive can work on a USB 2.0
    port as I thought there would be a lot of data transferred if playing back
    a blu-ray movie.

  16. The spec for USB2 is 480 Mbits/sec (USB3 is up to 5 Gbits/sec), and
    video tends to be in the general range of 30 mbits/sec (IIRC), so that
    should be plenty.

    Having said that, I have to admit that I was also surprised when I first
    learned that USB2 is enough for Blu-ray :)

    Not trusting my memory, I Googled and found this page:
    http://en.wikipedia.org/wiki/Blu-ray_Disc

    And here's a quote from
    http://en.wikipedia.org/wiki/Blu-ray_Disc#Bit_rate
    farther down the page:

    "Bit rate
    For users recording digital television programming, the recordable
    Blu-ray Disc standard's initial data rate of 36 Mbit/s is more than
    adequate to record high-definition broadcasts from any source (IPTV,
    cable/satellite, or terrestrial). BD Video movies have a maximum data
    transfer rate of 54 Mbit/s, a maximum AV bitrate of 48 Mbit/s (for both
    audio and video data), and a maximum video bit rate of 40 Mbit/s. This
    compares to HD DVD movies, which have a maximum data transfer rate of 36
    Mbit/s, a maximum AV bitrate of 30.24 Mbit/s, and a maximum video
    bitrate of 29.4 Mbit/s."

    I was very close when I stated the Blu-ray bit rate above - only off by
    a factor of 2 :)

    Thanks Gene for the information.

    On my Sony Blu-ray player I can display the video bit rate on the screen
    while playing a video. There is a sudden increase in the video bit rate for
    fast action scenes and less for still landscape scenes.
    Some people buy an old TV series expecting it to be better on blu-ray; it
    would be if it was from a film camera recording. The only advantage of an
    old TV series on Blu-ray is that you can fit more episodes on to a single
    disc.

    I have also been fooled in downloading a YouTube video that claims to be in
    HD only to find that the source appears to have come from VHS tape so there
    is no lift in quality.

    When writing to a external blu-ray drive it might be slower than writing to
    an internal blu-ray drive.
