I believe that Scratch can OUTPUT ProRES correctly. I have done it on a few jobs without issue.

I understand this only too well Mako, this was a “real” DIT who got carried away looking at all the material from all the different cameras and was momentarily distracted.

 

I won’t say who it was or upload their credits but this was a well established and experienced full on DIT.

Point of clarification,  x.264 is a version of a H.264 compliant encoder.  The encoder can be whatever someone wants to program as long as the result can be decoded by a compliant decoder.  The comparison would be the Main Concept version vs x.264 and others.  According to the Moscow tests, x.264 is better.

ProRes is of course a proprietary licensed codec.  The non Apple versions are sometimes OK but they do sometimes fail distributors QC.  So yes,  be aware you may need to create deliverables on a Mac.

Y'all take care,

Or AJA's for that matter. Generating a ProRes file with ffmpeg, then
transferring it via network to an AJA KiPro or KiproRack will result in
the file appearing in the deck's file list but not playing back.

As has been touched on, there are a few windows apps that do encode
proper prores, including Nuke.
I just went to the site and did a search on ProRes and ProRes codec, and
came up with zero results.

Which versions support exporting in proper ProRes? Any limitations?

Will it output ProRes 4444 with alpha properly?

Thanks.

I can't speak for ffmpeg specifically but there have been a few windows 'compatible' versions of ProRes sold as actual products and i can front line attest to the fact they're not the same and the encoding was not up to scratch. As has been touched on, there are a few windows apps that do encode proper prores, including Nuke.

But it is worth noting that ffmpeg is free, open-source, runs on Windows, and can encode Prores. I have used it for this purpose to encode both Prores LT and Prores 422 on Windows.

While the decoding process is correct in ffmpeg, in the encoding there are things which make up the quality (you could see that in H264 vs X264, which was constantly improved), such work on open-source ProRes ENCODER did not happen due to small target audience / interested developers. So the way
ffmpeg does encoding into prores is either a bad approach on some codecs or an average "will do the job if the scene is not extreme" .

Official and approved products have just better encoding quality due to having the secret sauce from the fruit garden :)

My guess is that Geoff has his hands full and may not be interested in mucking about with installing ffmpeg and figuring out the proper set of command-line arguments to get it to output Prores 4444 xq, and I don't know if ffmpeg fits within his workflow. But it is worth noting that ffmpeg is free, open-source, runs on Windows, and can encode Prores. I have used it for this purpose to encode both Prores LT and Prores 422 on Windows. 

According to the ticket in ffmpeg's bug tracker that was used to track the addition of Prores 4444XQ encoding to ffmpeg, the syntax for such encoding was to be:

ffmpeg.exe -i input -c:v prores_ks -pix_fmt yuv444p10le -profile:v 4444XQ output.mov

It appears that ffmpeg added support for Prores 4444XQ encoding back in late June 2017.

Hi Mark, 

I think you are looking for TrueMotion by Real D: https://www.reald.com/#/truemotion
Although I did install a trial once, I didn’t have the chance to really test it and see if it performs as well as it promises.

Hello Mark.

Real D - True Motion


The demo clip was shot on an ALEXA. The software can work directly on ARRIRAW frames.

Hi everyone,

I'm trying to track down a link to a HFR software demonstration I saw not too long ago.

They'd shot demo material (of dancers in an airplane hangar I think) on an F65 at 120fps. And their software allowed you to take the 120fps footage, and adjust the frame rate and attendant motion blur in post. So you could restore a 24fps @ 180 degree shutter look, to 120fps material, and ramp smoothly between the two.

Can anyone remember the name of that software, or point me in the direction of the tech demo for it?

What Tessive did with TimeShaper is a lot more sophisticated than anything (I believe) After Effects will do. TimeShaper uses sophisticated filter kernels, similar to those used for high quality image resizing, but applied in the dimension of time rather than space.

It’s easy in some software to cut the raw files down.

It’s not so easy with others, it’s a brute force job and with 50 folders per camera to trim and zip it’s time consuming and I need to get out on my bike after a few hours of it.

Of course I can’t trim compressed folders without going through an edit so I’m uploading the compressed files as they are.

As always there appears to be one lot of rushes missing/faulty, don’t tell me I should have had a DIT, last time this happened was the last time we had a DIT!

I’m hoping the manufacturer, who was there, has a copy. We do have 2 variations of the camera concerned just not the third so it’s not the end of the world.

 

I’ll put the raw files up first and then add pages of UHD QT next, I’m going to try not putting them on YouTube or Vimeo and host them on cmltests.net directly as h264 that I create. The full res QT files will be DNxHR 444 12 bit because I’m not going to play musical computers and transfer everything from a blazingly fast Windows machine to a sluggish Mac just to produce ProRes.

I’ll probably use Handbrake to produce the h264.
