first of all, scratch is a good system.
And as any system, it has limits.
In performance and in its business model.
As there are some different definitions (between post-veterans/studio owners and employees and customers of the manufacturer assimilate, the company behind scratch) of 4K requirements, market outlooks and postproduction workflows, this thread should easily give orientation for customers of red what scratch, being the only system which can operate at 4K allowed by red so far,
what the scratch software exactly -can- and -cant- do.
- 4K display. Some people (i am one of them) who mastered fullfeatures @4K say that it is crucial to monitor 4K at 4K, as noise, aliasing, and grain might be invisible at 2K monitoring. The scratch system so far has no 4K display. It is possible to view 25% of the images content, pixel by pixel, on the maximum display of the system which is 2K resolution.
- 4K realtime. This is a main source of confusion. Scratch cant decode 4K redcode raw in realtime in its full quality. By switching to lower qualities decode (as raw wavelet datareduction as used by the red camera easily allows), the station can read 4K @ 2K in RT. This is a great advantage if working in 2K - but the redcode raw source footage being processed at 4K requires a minimum 1:3 overhead in time.
- 4K FX. As any nvidia graphics card basing computer today, scratch, equipped with decent graphic cards (Quadro 5600 etc) is able to process 4K media in realtime. However, this does not apply to redcode raw, as the high-quality-debayer of this format overloads such as computer.
These are the basic limitations of the so far -only- allowed 4K redcode raw system. No 4K display (in general), no 4K RT (with redcode, no problem with decoded data), no RT 4K FX (once more, available with -dpx- sequences, but not with redcode raw).
I have been pointing out that these things seem to be a restriction and limitation to users who are used to a 4K RT workflow - in many posts.
In the recent week, a employee of Assimilate has been erasing these posts - backed up by the argument, that customers might be misunderstanding these facts. Many of the posters and readers of this discussion board were anrgy about this.
Therefore, i -condensed- these topics in this thread.
Beside these technical restrictions, people have been complaining about the business model of assimilate. While i agreee that this is understandable, this is a business decision of assimilate, the 48-month old company which has only one product: Scratch. They have to protect their product, as they have no other one. And especially if they are aiming at a exit-strategy (pure speculation).
Even as i pointed out months before the red camera was released, that not having a software for the customers of RED would cause the stir we are seeing now, it is important to understand that assimilates business method right now is to give customers an -individual- pricing, and therefore listprices might be causing problems. This has to be respected, even if some people (as me) say that this business model is the -exact- opposite of what the company red brought to the markets.
Closing this post, it is important to know, that there are many 4K realtime display, FX and processing alternatives in the market - which have more firepower than scratch regarding 4K RT i/o. And also more companies having more expertise, tradition and sheer number of supported raw-workflow.
Not only from the country i am living in (Germany, that would be DVS clipster and Iridas Venue among others), but also from the UK (filmlight baselight, quantel) , japan etc.
Scratch is a good software, and we might want to add it even to our -heavy- DI gear, but it is important to discuss these limitations and the market outlook.
If this sub-forum of reduser.net will be continously censored when discussing, besides the good things scratch offers, its weaknesses, then it is time to take this discussion elsewhere - and have this subforum become a marketing device instead of a discussion forum. I hope that this thread will prove the opposite - as anything else would be the opposite of the red approach.
