Re: 60Mbp/s vs. 100Mbps - Supprising Video Samples
Yeah, I know - VLC plays them back just fine, but one wants to edit, right?
Heck - Catalyst Browse plays them full speed! |
Re: 60Mbp/s vs. 100Mbps - Supprising Video Samples
Since they did not include the card structure, just the files, FCPX would not import these, but EditReady easily converted them to ProRes. Threw one into a 1080p timeline - played back easily even before rendering was finished. The ProRes plays back and edits beautifully, however I do have a 6TB Thunderbolt raid 0 on my 27" iMac.

Re: 60Mbp/s vs. 100Mbps - Supprising Video Samples
Hi guys,
Maybe Piotr will need a faster cpu for this camera format? I was considering this camera, so tried the first clip here. (thanks Zenes). I use Edius and my old i7-920 machine played the clip without stutters or frame drops but scrubbing was not smooth. This tells me what I already knew, that my old machine is out of it's depth with 4K. I had the same problem with 4K mov files from my GH4 so it's par for the course and I now have an i7-5960X machine. With the new computer I found that in a 4K project Edius 7 can plays 3 streams of the MXF file consistently, without frame drops, scrubbing is smooth and precise. While playing, Win 7 task manager reports 16 logical cores at 45 - 95%. Since I deliver 4K as HD I put the same clip four times into a 25p HD project, where for some odd reason Edius handled it even better! 4 streams, 16 logical cores at 91 - 98%. Not tried adding filters yet but so far the camera format seems very editable, certainly no need to transcode, just need some power and a willing NLE... so just asking myself do I want the camera... |

Re: 60Mbp/s vs. 100Mbps - Supprising Video Samples
Zenes,
I tested your clips again on my friends super-fast computer and a 50" plasma HDTV (not UHD) and I must say something is terribly wrong with the quality - as if the clips were interlaced or something; there is a lot of jerkiness in panning and jagged lines. If that is the final quality of the troublesome X70 4k XAVC-L codec - the camera is seriously flawed... PS. I can see the same artefacts in VLC, so it's not Vegas fault this time. |

Re: 60Mbp/s vs. 100Mbps - Supprising Video Samples
Oh, and one more thing:
When comparing all these new 4k cameras using Vegas or other NLE, we must remember that not all of them (or their codex) have been made equal - and when something doesn't work (or works worse than the rest of the bunch), it's not always Vegas Pro's fault. As I have stated, 4k from the AX1/AX100 cameras plays back stunningly, with this "out-of-the-window" wow look. But I forgot about one more camera that also plays absolutely wonderful in Vegas: the JVC GY-HM200. Even though the native samples I have are in the dreaded MOV wrapper, they play full speed at Best/Full and the picture is amazing. Oh, and the 4k codec is 8 bit 420, but not overly compressed at 150 Mbps (the fps is 30p). Those clips play Best/Full even on my lousy laptop! If only the sensor was a tad bigger and better in low light... Piotr |
Re: 60Mbp/s vs. 100Mbps - Supprising Video Samples
Thanks for providing the clips so I can test if my computer can handle them before getting into 4k.
I have been able to download the 3 mxf clips, import them into Premiere Pro CC and put them together on a 1080p and 3840p timelines. I've zoomed and split and sometimes the playback is a bit jerky, but that is because I am running out of RAM. I tried a 3 clip multicam 4k sequence, but CPU bounced around 100% and RAM maxed out. I don't know how I would go at 50p. More RAM is next on the shopping list. My computer is a DELL Vostro 470 i7-3770 3.4GHz 8GB RAM NVIDIA GTX-660 1920 x 1080 monitor Windows 7 Pro 64 bit |

In fact, 1080/25p material from EX1 or FS100 looks better than the 4k in the clips you provided - I hope Sony will issue yet another X70 firmware iteration soon to take care of these XAVC-L motion artefacts in 4k... |
