TOPIC: Mac ProRes 422 to Windows Lightworks?

Re: Mac ProRes 422 to Windows Lightworks? 1 year, 10 months ago #26517

Hi Jeff DePonte,

Yes it was an excellent choice. There are probably faster graphics cards but it is great to edit full Hd 1920x1080 projects. I also network a 2nd Alienware Laptop (Model )M14X which also runs LW. It has an onboard Intel Graphics HD4000 and an NVidia 555m. I also have Edius running on it to take advantage of Quicksync and the Sandy Bridge Processor. Makes rendering H264 for Blue Ray so quick.

Both of these laptops are very well suited to video editing. I would say they are not the cheapest though

Hi Cookiecutter,

As soon as I can I will re send you another example file. Maybe only 30 seconds this time.

Cheers

Ronnie

Although LW11 Pro works very well now with ProRes, faster handling of this codec is keenly awaited. (I find DNxHD is much easier to work with - less processor intensive)

PS: I'm currently testing a beta version of HDCinematics' new AVCHD transcoder which incorporates timecode into the proxy and HQ ProRes transcodes. We hope to offer this 'one stop shop' Lightworks solution very soon to the growing number of producers shooting AVCHD on DSLRs and pro-sumer cameras which do not record native timecode.

Oz,

What do you mean by "faster handling of this codec?" Is there something significantly "slow" about using ProRes files?

And, for the record, the reason that I require the ability is that I have many, many hours of footage in this format, both for completed projects and projects awaiting post production. I do NOT want to have to reprocess the camera originals!

Thanks for your reply, I am very much interested in hear more from you.

Jeff

No, you should not need to re-process your files. I've spent the last couple of months streamling an efficient workflow path for AVCHD 'prosumer' cameras and DSLRs for 'professional' use in LW. Although LW on a high spec PC will handle native AVCHD, that recording system is not really designed as an editing format so transcoding to a codec that is editor friendly (such as ProRes) is more efficient. (so long as you have the disk space)

According to comments from the Moderator on this thread, LW developers: "...have also made some improvements to ProRes file handling. These improvements will be available in a new build shortly."

My tests on relatively low spec hardware suggest that if I compare identical Mbit rate transcodes from AVCHD to Avid's DNxHD vs Apple's ProRes, the former is a lot easier to work with ie: uses less processor power = faster, easier editing. I am reliably informed that ProRes requires substantially more processor power to work with than DNxHD for the same Mbit rate. However,(correct me if I'm wrong) ProRes will support frame rates of 50P whereas DNxHD only supports 50i so as I shoot 50P, any future 'improvements to ProRes file handling" are eagerly awaited by this writer!

As I gave up shooting interlaced video a long time ago, getting DNxHD to support progressive frames is critical! With all due respect to the good folks at LW, how did all of the films that they tout as having been edited on their system get edited on their system?

Also, since I have at least a couple of folks watching this space, a question: are there any computer sellers that know how to successfully build LW-capable systems? I am interested in a tower of some sort. I discovered a seller in the US called Puget Systems. They have a box called Serenity that should do the trick:

Puget Systems Serenity

...for around $2400.

Does this make sense?

DNxHD does and has always supported progressive video. 50p is not a broadcast standard.
