    March 26, 2012 at 4:44 am in reply to: Editing Monitor doubling as field monitor

    I have a pelican case that I mounted a monitor in. I drilled 4 holes through the lid and mounted a $50 used 17″ monitor using aluminum spacers. I have a flip down piece of plastic that doubles as a sun shade that protects the screen from everything else that I tend to throw into the case (batteries, chargers, LED lights etc.

    It is a little large for true run-n-gun, but if you are doing anything in studio or a true location shoot, it is absolutely fantastic. I would say that the total price was less than $200.

    Hi,

    I had this issue when shooting a commercial spot for a mattress company.
    The problem with h.264 is that the video does not contain all of the information about each frame. It basically has information about what has changed in between the full frames (I-Frames).
    When you have a sweeping pan, the hardware has problems keeping up with the changes and shows a stutter. This is why is is not the same every time you play it. It just depends when the hardware is too slow.

    If you export into an uncompressed codec such as an AVI, you will not notice the problem as much.

    Believe it or not, I tried all of the frame blending tricks too. One of the tricks is to add a very tiny amount of grain into the image. I am not sure why it works, but it seems to.

    I am using an Nvidia card with MPE enabled, have an overclocked i7 and 16gb of RAM. On a timeline with multiple layers and effects, smooth playback is not happening.
    1080P h.264 is just really not easy on the machine. When I render the timeline, my CPU monitor will show 8 cores at 80-100% and sometimes up to 16gb RAM in use. This is not the case when I am editing with something like an HDV at 1080P.

  • I have found that on occasion, for no particular reason, that one of your clips in the timeline will simply go twitchy like that. If you alt drag the same clip onto it, it will replace the clip with another version of itself and fix the problem.
    I have found that the other solution of exporting into an uncompressed file prior to transcoding works as well.

    The playback will also depend on what you are using for a codec. If you are editing something like an h.264, you may not get great playback unless it is rendered.

  • If you are using that shutterstock image, since it is black and white, all you need to do is place it on top of your other footage. Now when you first do this, you will only see the black and white image, but if you go into the opacity tab in the effects controls and change it to multiply, it will get rid of the white.

    Mpeg1 is considered to be kind of a universal playback codec. It will play on pretty much anything.

    I would like a 15mm mount video record button. That is all.

    I use a splitter coming straight out of my zoom. I monitor one of the jacks and run the other through a headphone volume control into my 5D. This has worked incredibly well for me. I turn up the volume on the zoom to full and then set the 5D input to 5 clicks above the bottom. I then adjust the volume control on the cable until my meters are good.
