بيع HDMI إلى محولات SDI لكاميرات DSLR التي تغير القرار أثناء التسجيل
مضى على هذا 14 سنة. قد تكون المعدات والأسعار قد تغيّرت منذ ذلك الحين.
ما توصّل إليه النقاش
- ويتيح التصميم الأسود لشركة HDMI إلى محولات SDI في ثلاثة متغيرات للمعدات: التغليف الأصلي، والرسوم الثقيلة، والرسوم الثقيلة المحتوية على بطارية متكاملة، وجميعها تقبل ما يصل إلى 31 فولت من مفاعل DC وفقا للمصنع.
- Early generation Blackmagic converters in the original casing accepted only 14 volts or less, while newer generation models with the same external appearance accept 12 to 31 volts and can be identified by a '2' at the end of the serial number.
- Blackmagic mini converters can handle resolution drops when recording from DSLR cameras, though the response time varies and some firmware versions may not handle the transition properly.
- The Blackmagic HyperDeck Shuttle recorder functions as both an HDMI to SDI converter and recording device, but does not handle HDMI resolution changes during recording and cannot be upgraded to support this feature.
- Mini SDI connectors on devices like the HyperDeck Shuttle are mechanically fragile and require careful handling to avoid damage.
- Powering HDMI to SDI converters from battery sources (P-tap) is feasible with proper voltage specifications, avoiding the need for external voltage regulation cables on newer models that accept wide voltage ranges.

- The discussion focuses on DSLR models from 2012 and earlier, with primary examples being the Canon 5D Mark II, T2i, and 60D.
- Firmware versions affect converter performance, and some versions may not handle resolution transitions properly according to user reports.
- The HyperDeck Shuttle's inability to handle resolution changes during recording was stated as a limitation that could not be upgraded.
- Information about resolution change handling in the HyperDeck Shuttle 2 model was not confirmed through direct experience in the thread.
