FS7: prores, xavx-i and photo Jpeg

I am playing with codecs, on my windows machine I can export from xavc-i to photo jpeg. These files are large, but when I encodee them to Prorers the files become even larger 500 mb vs 1,4GB that seems overkill for 20 seconds of footasge (4K).

Or isn't it?
 
It is the preferred codec for some stock agencies. I thought it would be smaller then photo Jpeg. But is isn't.
 
I upload all stock footage as ProRes and I don't worry about the file size. It is what it is. I have no doubt that ProRes is preferred over PhotoJPG by higher-end customers, and it is better to give customers what they want to buy rather than what would be easier to upload. All the major stock footage agencies accept ProRes.

The compression/quality ratios of the various intra-frame compression methods are only marginally different.

The big compression leverage comes when you allow inter-frame compression.
 
Well, get a model release next time! The key is to ask nicely and most animals will sign. Give 'em carrot.
On a different topic, I wonder if face detect AF on my Z280 would track on that face.
 
Any tip for Stock footage export for us Windows users?

That photo-jpeg workflow kinda put me off doing more stock work.
 
Photo jpeg is 8 bits. I started using Davinci and Catalyst prepare and ffmpeg for export in Prores 10 bits. Extra step. But doesn't matter the real bottleneck is the slow internet speed.
My upload speed is 30 mbps but the transfer speed never exceeds 3,5 mbps.

I use catalyst to make subclips, that doesn't work in Davinci (or I can't) Davinci cannot export subclips I found out but maybe that is a problem of the 16 beta version.

I'm not sure I understand exactly what you mean, but if you are talking about taking something like a 60 second clip and cutting it down to just the best 20 seconds, or maybe two 15 second clips, or three 20 second clips, or whatever, and exporting those out as new standalone clips (graded or ungraded) -- Resolve certainly can do that one clip at a time or in batches of hundreds of clips at time. I do it every day when I'm processing stock and/or b-roll. But maybe I don't understand what you mean by "subclips".
 
Yes cut a longer clip in smaller clips and export them. Didn't work last time I tried in Davinci 16 beta. Might be a beta problem. And Catalyst Prepare works very well too (and in Catalyst Prepare these clips are named subclips). But I'd prefer the Davinci way.

I'm not interested in running any beta software, but I can vouch for every version of Resolve from 10 to 15. I doubt that they would change anything so basic as the delivery options, so you better look again. Is there no option for "Render: Individual Clips" on the Deliver page?
 
If you use Premiere Pro CC 2019 on a windows machine- it's been able to transcode to Prores since Jan 2019- at least. As has Media Encoder.

Oh wow, i have been sick from work for a while, so only done some small edits here and there. Still on CC 18. Upgrading now!

Thats gonna be a game changer for sure, for stock. Im at 300mbits fibre so dont care about size.

Yes there is, that is the way I always export clips, but Davinci (the 16 version), does that only half, each individual clip is rendered, but when a clip is cut in two it doesn't render both halfs.
The public Davinci beta versions often work fine.

I think they added the ProRes output capabilities a little after last Thanksgiving. (It was a Holiday present from Adobe!)
First job I output to Prores from Premiere was in mid-December. Most of my clients don't request it, but it's a great feature to have available.

Sounds like you need to change the clip naming settings to add a suffix to each clip so every clip has a unique name. The problem you are having is that the first clip renders, then the second clip renders with the exact same name so the first clips is overwritten. But if you check the boxes for unique clip names then every clip will have a unique name this based on the original file name plus some extra digits at the end based on the clip's order in the timeline. No chance of overwriting each other. I'm willing to bet that is what your issue is.
