    Syncing Audio und Video via Metadata TC in Premiere Pro (Tentacle)

    There's a tutorial for auto confirming audio with timecode in Premiere Pro at the Ambient University website: http://ambient.de/en/university/
  2. In New Zealand, the copyright "Commissioning Rule" gives copyright to the individual or company that commissions the work. If the production company has an obligation to pay you for recording the project, then they own the copyright from the outset.

    MKH50, Sennheiser vs Rycote mount?

    Back in the late 1980's / early 1990's when the MKH50 first came out, a similar suspension to the current suspension was supplied. It had the same pastic components as the current design but the rods were about twice the current length which resulted in less floppiness. It was a great mount. I did succesfully modify a new suspension with rod from a hobby shop.
  4. I now have an X3. I do check Metacorder still works from time to time with my Metric Halo 2882, particualrly after an OSX update, as it's always a potential backup recorder.
  5. Moved on from Metacorder after 11 years of use in mid 2016. Yes, blantant self promotion about software that hasn't had any serious upgrades in 10 years. Despite the fastest metadata entry available even in 2017 and a slick one button false start routine, the absence of any development has resulted in Metacorder slipping well behind the hardware competition.

    Tablet running Wireless Designer

    I power my tablet from a 12 volt to USB power adapter which has 4 outputs for charging other stuff as well. However, this all has to be powered via a DC-DC converter to run it off my cart power to prevent computer garbage noise from getting into the audio system.

    Tablet running Wireless Designer

    I have been running a low cost Windows 10 tablet (Linx 1010B 10.1 inch - Intel Atom Z3735F Quad Core) for about a year for use with Wireless Designer and a Wideband Venue along with running Ambient’s ACN network. I purchased the Linx 1010 as it has 2 standard USB ports plus a micro USB port for charging. I use one USB port for connection to the Venue and the other for other uses such as a SD card reader or connecting to my Cantar X3 via a network adapter. Wireless Designer works fine for me but it’s more a remote viewer rather than a control for the Venue. The lowish resolution screen and the vague touch screen response doesn’t really translate into an elegant and versatile computing experience. Perhaps a Microsoft tablet would be preferable and I’d consider that as an option if the Linx tablet died.

    studio fans...

    A 24" is the quietest Mole as it can operate at a lower speed compared to smaller size fans for the same airflow. The problem that I experience with Mole fans isn't the noise they make when gently blowing an actors hair, it's the additional background fans deemed necessary to move background leaves on trees, curtains, etc. The artful wafting of a cutter does not appear to be in anyones job description these days.

    So who showed what at NAB

    Dante Broadway 8x8 & 16x16 chips. These chips bridge the gap between the current 4x4 and 32x32 Dante chips and better suit location audio equipment channel counts. https://www.audinate.com/products/manufacturer-products/dante-broadway?link=h-car

    Your first sound setup or kit ever

    First kit purchased in 1985: Nagra 4.2, Sennheiser 416 in a Rycote basket, Beyer DT48. First kit operated - 1977, ABC Brisbane, Australia: Nagra 4.2, Sennheiser 815 & 2 x 415, Rycote baskets, EV 667, a couple of really big Sennheiser lavaliers and DT48's
  11. I stand corrected regarding the roller shutter on the Arri's, but I'm told it's damn near a global shutter.
  12. Genlocking via timecode is Arri's recommended practice. It's noted in the current Alexa Mini and Amira manuals and firmware notes. TImecode works in this instance because the camera has a global shutter and the TC is triggering a single full sensor read of each frame rather than a traditional and more complex TV scanning sequence. The Alexa and a Mini with the genlock via BNC mod can use black burst or Tr-level sync as an alternative. The only caveat with using TC as genlock is that a stable, high quality generator must be used.

    Aaton XTR sync start/stop

    Aaton Code is on the edge of the film outside the scanned picture area. There is no way to use this timecode without the Aaton Code hardware reader on the telecine machine. If the telecine has the reader then as Bash notes above, you can have that timecode burnt into the vision. Without the Aaton code reader on the telecine, the only practical way to sync the film with audio is with a slate, either plain clapsticks or a timecode slate.

    Aaton XTR sync start/stop

    The "Aaton code" is the same SMPTE/EBU timecode format that is used in audio files of the currently available professional audio recorders. If you have the technology to read the Aaton code from the film - a telecine with the Aaton timecode Keylink hardware reader and the Keylink / Indaw software, you can sync audio with matching timecode to the film. Alternatively, you could output the video though the Keylink hardware reader and software and then sync the audio in and Avid, FCP or Resolve.

    Oscar Technical Award BS.

    Lectrosonics Digital Hybrid does not transmit analogue audio! The scheme uses FM modulation to transmit a digital signal. Note that it is a digital signal, not a complete stream of compressed or uncompressed digital audio. From Lectrosonics White Paper on the subject: "The audio entering the transmitter is first sampled at 88.2 kHz and converted to a 24-bit digital audio stream. The digital audio is analyzed by a DSP-based algorithm that attempts to predict the next audio frames on a continuing basis. The prediction is then compared to the actual audio stream that follows and a difference (error) signal is generated. The error signal is delivered to the output of the transmitter and transmitted with a wide deviation FM modulation. A compandor is applied to the error signal to improve the signal to noise ratio of the radio link, but no compandor is applied directly to the audio. Inside the receiver the same predictive algorithm is operating. The error signal is received and then applied to the predicted audio stream to restore the original digital audio stream. The 24-bit digital audio is then converted back into an analog audio output" It is an innovative transmission scheme in it’s own right and thus patended (applied for in 2002).
