  1. I just realized that ffplay (the ffmpeg player) will show histograms, video waveforms and vectorscopes.  Ffplay has to be one of the smaller applications that provides such capability.

     

    These commands worked on my Linux terminal.  Not sure if the syntax changes slightly for the Windows command line.  Note that the word "video" in the commands should be replaced with the name of your video file (for example, my_video.mp4).

     

    I saw both simpler and more complex versions of these commands when I did a web search.  If you try ffplay and have problems, please post your commands, and I will see if I can help.

  2. Shotcut is open source, and is fairly lightweight and has histogram and waveform (apparently, no RGB parade and no vectorscope).

     

    Kdenlive is also open source, and seems to offer all the important scopes.  It is probably lightweight, but not as much as Shotcut.

     

    Both of these NLEs have Windows versions.

     

    There are other open source NLEs and post production applications, but I am not sure what scopes are offered nor if there are Windows versions.

    Which RAW codecs did these use?

    The F900 was used to shoot a Star Wars movie in 1999.  It shot 422 HD, uncompressed (I think that the bit depth was 10).  It's successor the "f950", shot 444 uncompressed and was released in 2003-2004.

     

    The original Varicam was released in 2001, and it could shoot 720p HD, with a variable frame rate from 4fps-60fps.  I don't recall, but I think it shot uncompressed 10-bit 422.

     

    The Dalsa Origin shot 4k raw in 2003-- I don't think that there were raw "codecs" back then.

     

    By the way, the Thompson viper shot 10-bit log, 444, uncompressed in 2002-2003.

     

    The 4k raw Dalsa Origin existed years before the original Red prototype saw first light.  In addition, quite a few blockbuster features and high-end commercials were shot with f900s, f950s, Varicams and Vipers long before Red appeared.

     

    So, the claim that "the digital [film] takeover started with Red" is a bit dubious.

    The worst part about Adobe is that they are leaps and bounds ahead of all of their competitors.

    Disagree.

     

    I have seen several new, heavily promoted features in Photoshop declared as breakthroughs that actually appeared years before in GIMP and other open source imaging software.

     

    I also don't see much difference between Lightroom and Darktable (and Raw Therapee).  If Lightroom has an advantage, please let me know.

     

    In regards to NLEs, I don't usually use a lot of fancy plugins, but there are certain features that I find in open source NLEs that I can't find in Premiere or other proprietary software (and I would avoid using proprietary software, regardless).

     

  6. I've always admired the Norms Travel Dolly, because it can be "underslung."  You just need to get sections of 1 1/4" tube/pipe for tracks.

     

    So, with the two stands, you can adjust the dolly height from the floor and up, with no need for camera risers to do so.

     

    Norms offers a less expensive starter kit, without the special stands and special under-slung arms (you can just use two standard C-stands with grip arms for under-slinging).

    What does him being Mexican have anything to do with it?

    It is the nationality of the physicist who found the solution to a long standing optical problem.

    maybe tupp is from mexico and is proud that it is a mexican that solves this.

    I'm not from Mexico, but no doubt some Mexicans are proud of this significant accomplishment.

    I am going to buy a video editing software, and I am choosing between Openshot and Filmora. Any thoughts or experiences with those two? Pros and cons?

    Hmmm.  Openshot is open source, so you don't purchase it.  Don't know anything about Filmora, but it sounds like someone might be attempting to promote it.

    Wonder if there can be in future a Tough E mount style solution where the Nikon Z mount screws off and gets put in the bin along with those expensive Nikon F1.8 lenses and a Techart Sony E mount screws on in place of it ;)

    It's physically possible.  It probably wouldn't be a good idea to discard the Z-mount contacts, if one has a notion to eventually use Z-mount lenses/adapters .

     

    For those unfamiliar, there are TOUGH E-mounts sold by Photodiox in brass and "silver."

    I just pulled the trigger for this camera. However, the firmware version is 1.6 something and canon's site is only offering 2.3. Where can i download a credible 2.2 version? I understand the 2.3 on ML will brick the camera.

    There is/was an ML version for EOSM firmware 2.0.3.  ML developer Daniel Fort has a 2.0.3 ML version from January 2017 on his bitbucket download page (scroll down to "magiclantern-Nightly.2017Jan13.EOSM203.zip"),

     

     

    Always make sure that your camera battery is fully charged before you attempt to install Magic Lantern.

     

     

    If you would like to downgrade your EOSM firmware to 2.0.2, and then install the latest builds for 2.0.2, here is Daniel Fort's tutorial on how to downgrade Canon firmware.  It is fairly easy, once you have the firmware (.fir) file -- just reflash the firmware the same way you would flash ML (except the SD card should not have the "boot flag" enabled).

     

     

    Always make sure that your camera battery is fully charged before you attempt a firmware update.

     


    Canon doesn't seem to have the EOSM 2.0.2 firmware posted for download, but here is the link that Daniel Fort gives for most Canon firmware (scroll to the bottom of this page to find the firmware links).

     

     

    The EOSM 2.0.2 firmware can also be found on this non-Canon page.  Scroll down to the firmware download link for "eosm-v202-win.zip" near the bottom of the page (it's not the "ksd291a_installer.zip" download link near the top of the page).  Windows (nor any other particular OS) is not required, once you have extracted the firmware from the zip file.

     

     

    In Fort's firmware downgrade tutorial, he seems to suggest that it is very unlikely that someone would/could tamper with compressed Canon firmware files (.fir)

     @tupp was right about gases and stuff, which is a really huge deal if you're trying to run a generator down there,

    I actually wasn't referring to running a genny inside a cave (which would be an obvious hazard).

     

    Natural noxious gases can collect in caves and mine shafts, hence, the use of canaries in underground mines.  Also, having a decent sized crew and cast in a small closed space can deplete the oxygen.

     

    If you are in a cave with a cast and crew and if you are not close enough to the entrance to feel a breeze from the outside, then you probably need to run an active ventilation hose/duct from the outside to the set (in other words, you need to pump fresh air into the shooting area of the cave).

  12. Don't know much about permits (and I haven't looked at your links), except that if the location/cave is in a park, you will probably need a permit from the parks department that has jurisdiction (municipal, county, state or federal).

     

    Also, there are significant safety concerns with caves (and mine shafts).  Here are some safety guidelines.  A lack of oxygen or noxious gases can kill you -- that is a hazard that you cannot see.

     

    If you will be crawling through tight passages, you will be glad if you are wearing a hard-hat, knee pads and elbow pads.

     

    Be careful!

    Ready to load ML on it. But It has firmware 2.0.3 on it and every build I see seems to need Firmware 2.0.2 to use it. Do I have to roll it back
