You originally made it sound like the 4k file worked with your LG UHDTV. You might have to contact the distributor of Timescapes and see what they recommend. Or at least suggest they conform their files to 2160p.

The Cineform file is 4096 x 2304, but tv is 3840 x 2160.

I am using a MacBook Pro Retina Display with OS X Mavericks as my player and it is able to work at 4k @ 30 & 24 FPS with the LG.

My problem is how do I down convert 4096 x 2304 Cineform to a 3840 x 2160 format?

Thanks,

Zebity

Sorry to inform you that you bought the wrong version.

When you don't have a display or playback facility that can use the Cineform format, the Cineform version is unusable for you, unless you run it through a Transcoding process and render it to a format and a crop you can display.

The 4K UHD - H264 3840 x 2160, 25Gb file would have been the right choice for you, or maybe even the 4K UHD - Prores 3840 x 2160, 120Gb (if you can playback ProRes).

Hi Coolscan & Co,

I have done some additional research and the combination of downloaded Cineform codec for QuickTime on Mac (the NeoPlayer for Mac, downloadable from Cineform web site) and Apples Compressor utility allow transcoding of 4K formats.

I tried ProRes 422HQ (3840 x 2160) , which turned 320 gb Cineform source to 280 gb mov file.

Playing this from MacBook Pro resulted in great image quality, but Mac could not keep up throughput and dropped sound. I tried to play with both QT and VLC, but both had problems with play back.

Now in process of transcoding to ProRes 422 and H.264 4k at 3840 x 2160 to see how these go.

The transcoding takes around 12 hours on 12 core Mac Pro, so testing different codecs is a slow process.

Cheers,

Zebity.

MOV files are terribly slow and kludgey due to the Quicktime engine being only 32 bit and poorly written. There has to be a better wrapper to use. I read about complaints from video producers all the time.
