What factors affect the speed of encoding the most?

Hi all

I'm actually very happy with the speed of encoding to DVD formats. I was under the impression that he was 'real-time' coding. Encoding 1 hour long PAL 48 kHz capture VHS to DVD only took about 30 m.

I opened the Task Manager and noticed that the two hearts of my Athlon X 2 5400 running hard during this process. So I guess that coding can use multiple cores.

My questions are:

  1. If I'm on a Quad core CPU what performance increase what I see with the above example encoding? 15 m?
  2. What influence hyperthreading there - if any?
  3. Do you expect that PE8 will support nVidia CUDA at some point? I noticed that the latest version of Roxio software don't.
  4. Will be slow encoding drops considerably when I started working with HD content?
  5. A Matrox hardware encoder work with PE8? They seem to only support Premiere CS4

I have SATA - II RAID 0, 2 GB of RAM, AMD Athlon X 2 5400 + and XP SP3

Justin.

The two factors that most affect your rendering, as well as your speed of encoding are:

(1) the power of your processor. So, Yes, in fact the upgrade to a quad core processor would make a significant difference in your performance. Your graphics card and RAM have no real effect on your rendering speed.

(2) the format and resolution of your video.

The resolution, for obvious reasons. It takes more time to display the 1.5 million pixels (hi-def) it does 345 000 pixels (standard definition video).

But the format can also make a difference. If you use the video from a non-standard source, such as a camera or a camera Flip, the program has to decode the video and more re-making.

And video AVCHD, because it is so highly compressed, takes the longest first to make.

In other words, the video from miniDV camcorder should make pretty quickly after you add an effect - that video from a camcorder AVCHD will take much more time.

  • What element is the limiting factor?

    Greetings.  A previous employee in my company had set up a a universal station machine Instron who communicated with Labview via GPIB to test.  This station has served us for the last 6 years, but now we need to upgrade and I do not know what component to upgrade.  Sorry that my first experience with labview (other than by using the front of the GUI).  In the last days, I read the manual of Labview and it seems fairly intuitive.

    Pretty much all I want to do is read my load and position several times per second.  In reading the other posts and the manual, I was able to move the instrument I/O Assistant in a flat sequence structure and surround by two millisecond timers.  He confirmed that the I/O intrument Wizard is the limiting factor in the block diagram.  Currently, we receive readings on each ms 160-220 (it is surprisingly incompatible).  It is the same value I get timers.  I wish that the time between the readings more as 20ms or even 2 ms.

    Speed your Instron GPIB just tells you that it would be able to send data fast enough. I do not know this instrument, but I would like to dig into the manual to see if it is possible together in a way he could make use of this speed. Perhaps by internal scripts, triggered material acquisition, low resolution... ask 1000 values once instead of a 1000 times.

  • Should we leave how much free space on the C drive before affecting the performance and speed?

    Hello!

    Hard drive of my new PC (C) is 1 TB (processor Samsung 7i, Windows 8.1). It doesn't have any other disk/partition. How this space is safe to use to store large files (videos, esp., stored in the native video library file) without harming the performance and speed?

    And if I create another partition (D) and just use it for storage, it will make much difference compared to the above?

    Thank you!

    Planning your Partitions

    The Question

    Partitions, how much should I have on my hard drive, what do I use
    each of them for, and what size should each one be?

    It s a common question, but unfortunately this doesn t have a
    only simple, just answer to all the world. A lot of people will respond with
    the way they do, but their response isn't necessarily best for the
    person seeking (in many cases it isn't right even for the person)
    response).

    Terminology

    First, let's rethinking the terminology. Some people ask "should I".
    partition my drive? That s the wrong question, because the
    the terminology is a little strange. Some people think that the word
    "partition" means divide the drive into two or more partitions.
    That s not correct: to partition a drive is to create one or several
    partitions on it. You must have at least one partition to use
    He who think they have an unpartitioned disk actually
    have a player with only one partition on it and it s normally
    Called C:. The choice you have is to have more than one
    partition, not that it's the partition at all.

    A bit of history

    Back before Windows 95 OEM Service Release 2 (also known as Windows
    95 (b) was published in 1996, all MS-DOS and Windows hard drives have been set
    using the file system FAT16 (except for very tiny to aid
    FAT12). That 16-bit only because were used for addressing, FAT16 has a
    maximum 2 GB partition size.

    More than 2 GB of hard disks were rare at the time, but if you had
    one, you must have multiple partitions to use all the available
    space. But even if your drive was not larger than 2GB, FAT16 created
    Another serious problem for many people - the size of the cluster has been
    more great if you had a larger partition. Cluster sizes increased from 512
    bytes for a partition to no greater than32Mb all the way up to 32 KB for a
    partition of 1 GB or more.

    More the cluster size, the space more is wasted on a hard drive.
    That s as space for all the files is allocated in whole clusters
    only. If you have 32 KB clusters, a 1 byte file takes 32 KB, a file, a
    greater than 32 k byte takes 64 k and so on. On average, each file
    about half of his last group waste.

    If large partitions create a lot of waste (called "soft"). With a 2 GB
    FAT16 drive in a single cluster, if you have 10,000 files, each
    lose half a cluster of 32 KB, you lose about 160 MB for relationships. This s
    back in an important part of a player that probably cost more than $400
    1996 - around $ 32.

    So what did the people? They divided their 2 GB drive in two,
    three or more logical drives. Each of these logical drives has been
    smaller the real physical disk, had smaller clusters, and
    so less waste. If, for example, she was able to keep all the partitions
    less than 512 MB, cluster size was only 8 KB, and the loss was reduced to a
    a quarter of what it would be otherwise.

    People partitioned for other reasons also, but back in the days of
    FAT16, it was the main reason to do so.

    The present

    Three things have changed radically since 1996:

    1. the FAT32 and NTFS file systems came along, allowing a larger
    partitions with smaller clusters and so much less waste. In
    with NTFS, cluster sizes are 4 K, regardless of the size of the partition.

    2 hard drives have become much larger, often more than 1 TB (1000 GB) in
    size.

    3 hard drives have become much cheaper. For example, a 500 GB drive
    can be bought today for about $50. That s 250 times the size of this
    Player 2Gb typical 1996, about one-eighth of the price.

    What these things mean together which is the reason to be old to have
    multiple partitions to avoid the considerable wastage of disk space left.
    The amount of waste is much less than it used to be and the cost of
    that waste is much less. For all practical purposes, almost nobody does
    should no longer be concerned about slack, and it should no longer be
    has examined when planning your partition structure.

    What Partitions are used for today

    There are a variety of different ways people put in place several
    scores of these days. Some of these uses are reasonable, some are
    debatable, some are downright bad. I'll discuss a number of Commons
    partition types in the following:

    1. a partition for Windows only

    Most of the people who create such a partition are because they believe
    If they never have to reinstall Windows properly, at least they
    He won t lose their data and he won t have to reinstall their applications.
    because both are safe on other partitions.

    The first of these thoughts is a false comfort and the second
    is downright bad. See the analysis of the types of partition 2 and 4
    below to find out why.

    Also note that over the years, a lot of people who find their windows
    partition that has begun to be the right size proves to be too
    small. For example, if you have such a partition for Windows and later
    upgrade to a newer version of Windows, you may find that your Windows
    partition is too small.

    2. a partition for installed programs

    This normally goes hand in hand with the partition type 1, a partition for
    just Windows. The thought that if you reinstall Windows, your
    installed application programs are safe if they are in another
    partitions is simply not true. That s because all programs installed
    (with the exception of an occasional trivial) have pointers to the inside
    Windows, in the registry and elsewhere, as well as associated files
    buried in the Windows folder. So if Windows, pointers and
    the files go with it. Given that the programs need to be reinstalled if Windows
    the fact, this reasoning to a separate partition for programs not
    work. In fact, there is almost never a good reason to separate
    Windows of the software application into separate partitions.

    3. a partition for the pagefile.

    Some people think mistakenly that the pagefile on another
    score will improve performance. It is also false; It doesn t
    help and often I hurt, performance, because it increases the movement of the head
    to get back to the page to another file frequently used
    data on the disk. For best performance, the paging file should normally
    be on the most widely used score of less used physical player. For
    almost everyone with a single physical disk than the same drive s
    Windows is on C:.

    4. a partition for backup for other partitions.

    Some people make a separate partition to store backups of their other
    or partitions. People who rely on a "backup" are a joke
    themselves. It is only very slightly better than no backup at all.
    because it leaves you likely to be simultaneously the original losses
    and backup for many of the most common dangers: the head crashes and other
    types of drive, serious glitches to power failure, near lightning
    strikes, virus attack, even stolen computer.  In my opinion,.
    secure backup must be on a media removable and not stored in the
    computer.

    5. a partition for data files

    Above, when I discussed separate Windows on a clean partition,
    I pointed out that separate data from Windows is a false comfort if
    He of done with the idea that data will be safe if Windows ever
    must be reinstalled. I call it a false comfort that's because
    I'm afraid many people will rely on this separation, think that their
    data are safe there and so do not take measures to
    Back it up. In truth the data is not safe there. Having to reinstall
    Windows is just one of the dangers to someone a s hard disk and not
    probably even one. This kind of "backup" falls into the same
    category, as a backup to other partitions partition; It lets you
    sensitive to the simultaneous loss of the original and the backup on many of
    the most common dangers that affect the entire physical disk, not
    just the particular partition. Security comes from a solid backup
    diet, not how partition you.

    However, for some people, it may be a good idea to separate Windows and
    programs on the one hand of the data on the other, putting each of the
    two types into separate partitions. I think that most people
    partitioning scheme must be based on their backup system and backup
    plans are generally of two types: whole hard disk imaging
    or data only backup. If you back up data, backup is
    usually facilitated by the presence of a separate with data only partition;
    to save just the score easily, without having to
    collect pieces from here and elsewhere. However, for
    those who backup by creating an image of the entire disk, there is
    usually little, if any, benefit the separation of data in a partition of
    its own.

    Furthermore, in all honesty, I must point out that there are many
    very respected people who recommend a separate partition for Windows,
    Whatever your backup plan.  Their arguments haven t convinced
    me, but there are clearly two views different here.

    6. a partition to image files

    Some people like to deal with the images and videos as something separate
    other data files and create a separate partition for them. To my
    the spirit, an image is simply another type of data and there is no
    the advantage in doing so.

    7. a partition for music files.

    The comments above related to the image files also apply to music
    files. They are just another type of data and must be dealt with the
    just like the other data.

    8. a partition for a second operating system to dual-boot to.

    For those who manage several operating systems (Windows Vista, Windows
    XP, Windows 98, Linux, etc.), a separate partition for each operating
    system is essential. The problems here are beyond the scope of this
    discussion, but simply to note that I have no objection to s
    all these partitions

    Performance

    Some people have several partitions because they believe that it
    somehow improves performance. That s not correct. The effect is
    probably low on modern computers with modern hard disks, but if
    whatever it is, the opposite is true: more music mean poorer
    performance. That's because normally no partition is full and it
    so are gaps between them. It takes time for the drive s
    read/write heads to cross these gaps. Close all files
    are, faster access to them will be.

    Organization

    I think a lot of people overpartition because they use scores as a
    organizational structure. They have a keen sense of order and you want to
    to separate the apples from the oranges on their readers.

    Yes, separating the different types of files on partitions is a
    technical organization, but then is to separate different types of
    files in folders. The difference is that the walls are static and
    fixed in size, while the files are dynamic, changing size automatically
    as needed to meet your changing needs. This usually done records
    a much better way to organize, in my opinion.

    Certainly, partitions can be resized when necessary, but except with the latter
    versions of Windows, which requires a third-party software (the and the
    possibility to do so in Windows is primitive compared to the third-party
    solutions). These third party software normally costs money and not
    any point and how stable it is, affects the entire disk.
    with the risk of losing everything. Plan your partitions in
    first place and repartitioning, none will be necessary.  The need
    to repartition usually occurs as a result of overpartitioning in
    the first place.

    What often happens when people organize with partitions instead
    records are that they make a miscalculation of how much room they need on each
    This partition, and then when they run out of space on the partition
    When a file is logically, while having plenty of space
    on the other hand, they simply saving the file in the score of "poor".
    Paradoxically, therefore, results in this kind of score structure
    less organization rather than more.

    So how should I partition my drive

    If you read what came before, my findings will not come as a
    surprise:

    1. If your backup set is the image of the entire disk, have just one
    single (usually c partition :));

    2. If you backups just data, have two partitions one for Windows and
    application programs installed (usually c :)), the other for data
    (normally D :).)

    With the exception of multiple operating systems, it is rarely
    any advantage to have more than two partitions.

    Hello

    The term of lightning speed differs from ISP to ISP. There is no certain download or upload speed which is called lightning speed. It's the same that to get good bandwidth to get higher download and the upload speed.

    Even the cable Internet high speed can be addressed as lightning speed. WI FI connection speeds are to your LAN (Local Area Network). A WI - FI router is unable to go beyond the speed provided by your ISP.

    I would like to be able to reproduce (essentially) the function of this feature of Audacity:

    Change of speed - Wiki of Audacity

    In Audacity, when I use the "change of speed", it changes the record in a way to play a tape slower or faster than normal speed (where pitch moves parallel to the speed). Hearing seems to have some tools that modify the two pitch and time both - the closer, I found to what I want to accomplish is the tool of 'Stretch and Pitch', with the stretch and Pitch Shift locked - but the end result is much worse (or at least significantly different) than what I get from Audacity.

    The goal with this must be able to set up a lesson on the interaction between frequency, height and time, and the problem I have is that it doesn't seem to be a solution in one simple step, in hearing to change an audio clip in the most basic ways. I'm afraid that I'm just missing where this feature can be, because it seems disconcerting that this operation is not really there. Any help is appreciated - thanks!

    That would be the obvious effect to use. How are you trying to change the pitch and speed?

    There is another method you can try to use the sampling frequency interpret in the Edit menu. Put in a sampling rate double that of the rate of your original file, will read at double speed and half the sampling rate will be read half speed etc. If you want to save the result in a new file, you will need to convert rates new sample to the original sampling to help convert the Type of sample.

  • Cold fingers should not affect the sensitivity of the trackpad to a remote AppleTV2?

    I experienced problems with the trackpad on the AppleTv2 remote while VoiceOver is enabled. (It works perfectly when Voiceover is turned off). We discussed it in the store today, but the guy was rerouted...

    In-store, it has worked for everyone except my mother cold fingers (which really needs, the voice off option as it is registered blind)-should affect the trackpad temperature or is she just unable to live in modern society?

    (Only Apple TV 4 has a trackpad, so I guess that's what you meant).

    Touch sensitivity depends on many factors, but the temperature and, above all, of sweating the difference.

    ATV4 settings for control of Siri is adjustable at what speed he reacts to movement of touchpad. Updated the speed slower can be useful.

    Also note that other remotes can be programmed to control ATV and there are many accessibility options that can make it easier for your mother to use.

  • 10 updates Windows Power affecting the Wifi adapter?

    Until this weekend, I was able to close the lid of my HP Pavilion and use an external monitor with wifi full power. However, after a series of updates from Windows last week, when I close the lid now: first wifi loses connectivity for 20 or 30 seconds, and then he picks up the connection, but speeds are greatly reduced and in some cases, connection with websites expires as evil to load pages.  Control speeds with cover facing upward and the lid down is day and night.

    I turned the power settings for the adapter on and out, tried to uninstall then reinstall the adapter, roll back the driver, by changing power options in Windows 10 but nothing seems to make a difference.  Its almost as if the updates included a substitution which affects the adapter wireless to save energy.

    What is the exact problem. You can try to delete the temporary files, run chkdisk and defragment your hard drive.

    Many factors are involved in the system of part of speed... We can demand to know what is the spec of your computer like what is the speed, ram and hard drive.

    Remove temporary files-> click on my computer-> right click on the local disk C :-> properties-> disk cleanup-> it will search and you view the task, you can continue by clicking ok.

    You can run disk defrag by clicking on the tools-> and select Defragment now.

  • the most important factor SSD Benchmark for 4 k images

    UserBenchmark: Samsung 850 Pro 256 GB vs SanDisk Extreme 240 GB

    Thanks for help

    Most of any generation current SSD will make hot quick reads. The most important factor for the use of Adobe Premiere Pro is the write speed of large file uncompressed.

    Some excellent records for Adobe to include:

    -Crucial M500, M550 (great for the price and have good performance write)

    -Samsung 830, 840 Pro, Pro 850 (stay away from 840 non pro and EVO as they are weak for large uncompressed file entries)

    -Intel 730 (were very $$$ when introduced, but prices are way less now and they are very good readers)

    You did not mention what type of files of 4 k, and it makes a huge difference. Highly compressed formats tax readers as much (GoPro, Sony AX100, GH4, etc) so that any 4 k uncompressed, Red 4 k and a greater willingness, etc. to be pushing a little more MB/s.

    I don't know there are others, but these models seem to be the most popular among users of the hardware forum.
