Canon 5D Mark II HDMI pérdida de señal al grabar y trabajar para el monitoreo externo
Tiene 14 años. Es posible que el equipo y los precios hayan cambiado desde entonces.
Lo que encontró el hilo
- El Canon 5D Mark II cambia su salida HDMI de HD a SD cuando comienza la grabación, causando que monitores conectados y convertidores pierdan señal durante unos segundos durante la conmutación.
- El Canon 5D Mark III y Canon 7D no exhiben este comportamiento de conmutación de señales al grabar.
- Installing Magic Lantern custom firmware on the 5D Mark II allows setting the camera to always output SD, eliminating the signal dropout.
- Some Blackmagic converter models require firmware downgrade to work reliably with the 5D Mark II's HDMI output switching, while newer Blackmagic mini-converters handle the switchover better than larger models like the Hyperdeck Shuttle.
- The 5D Mark II provides composite video output through a 3.5mm mini-jack port that does not cut out during recording, offering an SD-only alternative to HDMI.
- The 5D Mark III uses a USB port for video output in SD format rather than the mini-jack used on the Mark II.
Depende de
- The signal dropout is inherent to the 5D Mark II hardware and cannot be fully eliminated without either switching cameras or using custom firmware.
- Blackmagic converter compatibility varies by model and firmware version, with some models unable to recover from the Canon's HDMI handshake behavior.
- Alternative solutions like composite output require accepting SD resolution only on external monitors.
- The exact timing and success of workarounds may depend on specific hardware combinations and firmware versions used.
