  1. As far as I can see from the manual (I don't have a GH5), the Tether app has the option to write to the host PC as well as the card? If mplayer can play files while they're still writing as @tupp says then it would be able to do that so wouldn't need playback within the Tether app. It depends on your file but mplayer should at least smooth out the playback even if it does take some time to buffer. Its obviously limited by the nature of it being a wifi device but I'm out of options for getting it out of the camera any other way Yes, I was playing fast and loose with terminology but WebDAV mapped as a drive if you need it. In this application with mplayer we would just access it directly by ip address
  2. Turns out he went to work for Panasonic themselves...... http://www.dvxuser.com/V6/showthread.php?243166-DVX100-modification-HD-4-4-4-information-request/page2&s=628906553bed12c28f1ced68df216f3d That makes it an even bigger conspiracy theory than the other mob buying him out
  3. It has 8 storable focus points and you can transition from any to any with 4 preset speeds. The stick can do both manual focus or can act as a transition controller between 2 stored points.
  4. They've missed a trick by not having a music streaming service for us gentlemen of a certain age and calling it Instagramophone
  5. OK, here we go ... My understanding of what the actual setup is going to be is that it is pretty much akin to a photobooth but for slo motion video. (please chime in @18hans if I'm mistaken) I'm guessing its either an art installation or something to help people with their golf swing So, the flow would be as follows : Person enters booth Person presses physical switch to instigate recording After a defined period of time recording is stopped Recorded video is automatically replayed on a screen in the booth To instigate the recording, we are going to need some way of interfacing with that physical switch and putting the camera in record whether thats via wifi or with a shutter release cable and then having a counter and then stopping the recording. Consequently we are going to need some sort of microcontroller to handle the switch, the logic and the camera control, whether thats a Pi or an Arduino or some such. That bit is the easy part. The main issue is in having a way to extract files off the camera whilst still keeping it operative. Going into playback mode over wifi by spoofing being Panasonic's app is a non-starter as it kills the HDMI output. The standard USB mode will stop the camera functionality and just use it as a very expensive SD card reader whilst the Tether app for the GH5 has a few drawbacks It lists 'some limitations' when being used for video (I have no idea what they are but that doesn't sound good It needs a 'real' computer to run it on, which may or may not present budget and/or footprint issues for the application its being used for There is no way within the Tether app to instigate the record start/stop from a physical switch complete with the timer aspect If the budget does allow for a Mac to run it on then it might well be a workable solution as whilst its not possible to create the record start/stop logic inside the Tether app it is possible to create it using something like Keyboard Maestro https://www.keyboardmaestro.com/main/ to record screen macros of the record button being pressed and trigger it from a keyboard or even over midi. Midi might well be the way to do it because there are numerous small controllers and foot switches available off the shelf that could be used to handle the input from the user of the booth. That setup would keep the camera operative whilst it is transferring files back to the Mac. I'm not familiar with mplayer scripting so @tupp can chime in here but my presumption would be that it can be scripted to play the last file in a folder which could then be triggered by a watch folder option on the incoming folder? So, if you've got the budget and the space for the computer and the midi controller then this could be all you need. However..... If you don't or would prefer a smaller and cheaper option, my £40 solution would be to put one of these Toshiba FlashAir wifi SD cards in the camera : Because the camera doesn't know or care that it has these extra capabilities, there is no interruption to the camera operations as it just thinks it is an SD card. Although it serves a similar purpose to the EyeFi cards, its actually a lot more open in terms of what you can do with it and can be used just as if it were a typical network drive. So if you simply put "http://192.168.0.1/DCIM/101_PANA/P1010790.MP4" into mplayer then it will play that file off the camera without the camera being any the wiser or stopping you doing anything. This includes recording another video on the camera at the same time as you are streaming from it by the way ! Obviously, from a programming point of view, this openness makes it easy and fast to come up with custom solutions as it can all be done with standard http commands (it stores its file list on a specific html page on the card for instance for quick retrieval). It also means that you can remotely manipulate files on there to do routine file deletions (or moving to another drive in your network if you use it in Station mode) so it can be left running unattended. It can also run LUA scripts from the card to do even more stuff like being able to ftp in and out of it. Full documentation here : https://www.flashair-developers.com/en/documents/api/ From the control of the camera point of view, if you are using a Pi, then its a small Python script with the GPIO to get the user switch, instigate the camera record out of another GPIO (hack a cheap remote shutter release), timer, stop recording, get the file list html file off the card, extract the last file name and then fire up mplayer to auto play it. This script looks like it would be easily modifiable to get something up and running fairly painlessly https://github.com/baudm/mplayer.py/wiki/Player You could also instigate the record start/stop over wifi to the camera but you would then have to use a small router for the Pi to be able to address both the camera and the FlashAir card. If you do go this route, make sure you get the W-04 version obviously as this has the fastest performance. In summary ( ) the PC/Macro/Midi/Mplayer route would be something that you can get up and running with a USB cable quicker but at quite a big cost expense and footprint wise but the FlashAir route is cheaper, smaller and a bit neater if you can invest the time in the Python/hardware side of it.
  6. It was a hardware modification that took a tap straight from the A/D The original development thread is here http://www.dvinfo.net/forum/alternative-imaging-methods/20332-4-4-4-12-bit-uncompressed-dvx100.html There is a degree of conspiracy theory about who the company sold out to and if the buying company then went about acquiring all the modded cameras that were out in the wild. The strongest theory was that it was bought by a company that was about to start developing a cinema camera and needed to acquire the tech to stand up the patent they were filling for recording video in a RAW format. The sort of company that would have re-branded it in ALL CAPITAL LETTERS and put vaguely military industrial styling on it....... Allegedly.
  7. The issue/challenge is the automation aspect though @tupp in that the files need to be accessed from the camera directly without any manual intervention (ie taking the card out to be played in an external player or even using the camera's physical controls to instigate playback). I think I have worked out a sneaky solution to this problem though........ Tune in tomorrow night for details
  8. Thats what I thought before I went hunting for the EVF/LCD switch option. Spoiler Alert :::: There isn't one so kiss goodbye to one of your function buttons
  9. OK, I'll see what I can do. I was thinking of incorporating some playback into my controller anyway so it could be useful. I don't have a GH5 to test with so can you do me a favour and subscribe to this thread, that way you'll get an alert if I add something as there may be some testing I need you to do if I come up with a solution.
  10. Yeah, I'm probably going to have do something radical and download the user guide. And actually read it. Oh the humanity !
  11. OK Leave it with me. My initial reaction is to say this is more readily doable with a Sony camera because their remote protocol is a bit more rounded (not to mentioned documented) than the Panasonic one but I'll have a look.
  12. My view as a recent reluctant joiner to the Sony party via the A6500 is that as you are going to be spending a significant amount of timing cursing it and ploughing through endless menus shouting "Where the f** are you, you little f***" to hunt down and change a setting then you might as well spring for the A6500 over the A6300 as at least you'll be getting a bit better reward for your quests
  13. I don't know how they get away with the pricing to be honest. If you look at just Premiere on it own, the payments are roughly equivalent to leasing a £600 product where at the end of the term you send it back and get a new version of it (though in this case you are also getting a new version of it throughout the term) and start the whole process again. If it was a printer or computer or some such then its not a bad arrangement (though we could seriously debate the valuation of £600 for Premiere ) but the big issue is their biggest rival sells the equivalent outright with the same upgrade process for not far off a year's lease payments. It becomes "better" value when you go for the full suite but, even then, it seems so far out of whack when you now have a compositor like Fusion being included with Resolve for a few months "lease" payments on the Adobe suite. Over 3 years, the full suite, is not far off being the cost of the outright ownership of FCPX, Resolve/Fusion, Affinity Photo (Photoshop clone) and the MacBook Pro to run it on. I understand why so many users have the suite (as its no point having a different tool than the one you prefer to use irrespective of if its cheaper) but just that for me I'd be having to pay that monthly fee through very gritted teeth With regard to location/portable editing, LumaFusion is getting even more powerful with the integration with the Gnarbox (and actually might prove the reason to buy one) and the update to export XML. With an upcoming update to do external programme monitoring (via the HDMI adapter or even Airplay) it opens up even more options for people who need to have a more comprehensive editing setup while travelling. Not only using your hotel room's TV as a (very uncalibrated) monitor but with Airplay support you should theoretically be able to use another iOs device as a second screen monitor too. Quite apart from it being probably the best video editing app for mobile usage, I actually really like LumaFusion as an editor full stop.
  14. You are certainly not doing this transition to Sony by halves are you
  15. For $10K I'd be expecting a drone to be carrying me and the camera. And some luggage.
  16. Tiny footprint though. As a fixed remote operated camera with a small Panasonic pancake on it for a second angle, I think it has some utility for $199 but yeah even at half the price they ask for it here its a no go. Even at that price though its the cheapest way to get an MFT camera with a mic input !!
  17. I don't know whether they have designed them to do this but here is how I use the mounting clamps they provide with Amaran M9s as a bridge to connect my two together. Being able to break them down into singles (two of them will just about fit in the carrying pouch for one) and then use them individually or combine them to make something bigger makes them even more useful. You could definitely extend this out to connect four if needed.
  18. He was marvellous in Phantom Of The Opera but yes his latter work has lacked that same Spark and failed to Inspire.
  19. And your postman is currently in post-production on his debut short film My daughter is on holiday in NY at the moment so I just sent her a message asking nicely if she might pop in BH and pick one up for me. Well, I thought she was. I wasn't anticipating a reply with the time difference but got one straight back telling me that she is already back and that I clearly do not follow her blog posts
  20. Why don't they offer anything remotely like that price outside of the US? There are enough people with M43 lenses kicking about that might be tempted at that price to pick one up as a B cam. It would also do the company a world of good in laying a foundation for the brand to the potential buyers of their new camera.
  21. I remember this mod from back in the day and I seem to recall they had something similar on the horizon for the HVX200 before they sold up. Something like that is waaaayyy beyond my competence level.
  22. The 120 is definitely 50mbps as and the HDMI output is max 1080p when recording 4K 4:2:2 internal as @Anaconda_ says. The HDMI port is definitely 2.0b The problem with JVC is they often seem to spread their documents about across a few different corporate branded sites/distributors so its a bit of a hunt to find them http://www33.jvckenwood.com/pdfs/B5A-1634-00.pdf http://www33.jvckenwood.com/pdfs/B5A-1634-10.pdf http://pro.jvc.com/pro/pr/2017/nab/gyls300_inferno.html
  23. I completely forgot about that lens. Exception to the rule but some exception though. In a Canon mount with an MC-11 on a full frame Sony that would give a ton of fast options in combination with the crop mode and clear image zoom. The Fotga remotes with the zoom rocker make it quite decent to be fair. My upcoming remote lets you store clear zoom positions so you can press a single key for a specific focal length change like changing a prime
  24. Its a bit of different solution but something like this might be useful. Connect it to the HDMI output of the GH5 and it will wirelessly stream h.264 1080p to connected devices such as laptops, tablets, phones etc for monitoring using an application like VLC. As VLC can also record the incoming stream to the MacBook, this will give you a playback option on the MacBook that doesn't involve swapping the SD card and as it is compressed you will not have any issues playing it back. As its compatible with anything that runs VLC it also means that instead of the MacBook you could use a large screen tablet for play takes back wirelessly straight from the camera.
