Q: Does FCP X Support output larger than 4K ?

Does FCP X Support output larger than 4K ?

 

If not, is it likely to soon ?

 

That is all ...

    Thanks for the info David ... Apple are indeed dragging their feet.

     

    Safari doesn't support 360 video yet - Fierfox doe and so doe Chrome (best browser if you ask me).

     

    Will give Handbrake a try and hope Apple FCPX hurry up with their support.

    I believe there is some misinformation here.

     

    H264 - the CODEC - does NOT support 8K.

    Maybe you meant H265?

     

    The videos you posted are awesome, but they are NOT in 8K on youtube. They were RECORDED in 8K.

    The largest option for viewing them in youtube is 720p.

    There is a link that offers to sell a full 8K version, but virtually nobody has an 8K tv to watch it in full glory.

    Downconvert to 4K, well, that may make sense. I can readily accept as very plausible your argument about an 8K dowconverted to 4K looking better than one shot in 4K.

     

     

    Apple does not make video cameras, or tvs. You CAN edit 8K projects in FCP X.

    Is Apple "dragging its feet" just because it does not support H265? (insert perhaps 'yet' in the phrase)

    It doesn't... that's why when you pick h.264 in Compressor it says, 'UP TO 4096x2304.' Compressor doesn't even support 5k h.264 encoding.

    As 720p playback of the 8k video on YouTube...? Don't know why you don't get 8k...

    I get this in Safari...

    So I use Chrome to playback the 8k videos. The problem might be the PPAPI plug-in for Safari/Flash.

    Ok... I finally found a solution for encoding video up to 8k for the web. As I mention before Handbrake will encode 8k videos to MP4. I encoded an 8k video using Handbrake... not a good solution because you can't get the encoding bit rate high enough and you get artifacts in the video from the low bit rate. I don't know why Handbrake is able to encode 8k videos. H.264 can only encode videos up to 4k... so, Handbrake isn't an option.

     

    I did mention that Adobe Media can encode h.264 8k video. I was wrong... even tho you set it up for 8k encoding using h.264 the output is 4k.

     

    Upon feather web searching I discovered that the WebM PV8/9 codec can encode 8k videos for the web. PV8 is their h.264 encoder equivalent as VP9 is to h.265. This encoder is made by Google which owns YouTube. Both PV8 and 9 will play on the Mac using Safari. VLC will also play this codec. I also discovered that Adobe Premiere Pro and their Media Encoder has this codec, I have both.

     

    I put together some 8k+ images form my Sony A7rii camera into a video track and used the WebM PV9 codec for the final encoding. Here is the result on YouTube... https://youtu.be/KtVOPcNBhWI

    Unfortunately Safari doesn't support 8k video playback... you need to use the Chrome browser for playback. This short video is around 96 MB (very small for an 1:30 8k video).

     

    I decided to see about 4k VP9 encoding and wanted to encode to an over all bit rate of 20 Mbps which would be an average bit rate encoding for a 1080p h.264 video. Here is the result... https://youtu.be/0YsCyS4xrBc Overall bit rate: 21.3 Mbps... File Size: 150MB... an h.264 file size for this video is 682 MB.

     

    WebM PV9 is more efficient than h.264 encoding. Not only that you get the h.265 encoding capabilities right now using another codec, WebM PV9. From my understanding YouTube doesn't re-encoded WebM 8/9 encodings!!! What you send is what they use. YouTube also buffer WebM PV9 better for playback compared to h.264 encodings.

     

    For a stand-a-lone encoder there are a few online for the Mac. Make sure it encodes to VP9 and not to just VP8.
