My approach

4K, when it actually
makes a difference

Broadcast-grade quality serving your image, not for technical folklore.

Native 4K cameras

Canon CR-N500 PTZ, 1/2.5" UHD 60fps sensors. True native broadcast images, no upscaling from Full HD.

4K ATEM switcher

ATEM 1 M/E Constellation 4K for real-time switching. Broadcast-grade switcher used in television.

Encoding and storage

H.265/HEVC encoding for distribution, ProRes or DNxHR for archiving. High-speed SSD drives to handle 4K bitrates.

When 4K is worth it

Corporate films with high stakes, durable archiving, post-production reframing, XL or IMAX screen projection. Not essential for an internal webinar.

Paris, France, Europe

4K filming available on all my services. No hardware surcharge, ~20% additional cost for storage and workflow.

No. Full HD 1080p is the standard used by all TV channels and platforms. For most corporate events, 1080p delivers a perfectly professional result. 4K mainly adds real value for post-production and large projections.
Technically yes, YouTube supports 4K live. But it requires 25-40 Mbps stable upload and offers little practical value: most viewers watch in 1080p or below. Nomacast can record in 4K while broadcasting in 1080p for the best of both worlds.
For an 8-hour day in professional 4K: 400 to 600 GB depending on compression. Nomacast has the necessary storage on site, and the final video file is delivered via secure download link the same evening.
Yes. The Canon CR-N500 cameras are reference units in corporate production, used by TV channels and professional studios. Their 4K/60fps sensor, autofocus and colorimetry produce an image indistinguishable from a professional shoulder camera.
4K filming requires extra storage and may need a more powerful video gallery depending on the configuration. In most cases, 4K is available without significant extra cost. To be detailed in the quote.

Going further

An HD video doesn't tell you
who actually watched it.

4K and multi-camera production ensure visual quality. But without an analytics layer, you don't know who watched, for how long, or what questions they asked. Nomacast's interactive tools add that dimension.
