any thoughts on DNxHD vs ProRes?

Hi all,

 

as I just got an Atomos Shogun flame, I was wondering if some of you have already tested and compared both codecs?

Not necessarily only in relation to how they behave inV14, but also quality wise.

For now, I think I'd rather go with DNxHD 175 to work with in Vegas. Is anyone here workig with it in V13/14 on a regular basis?

Thanks!

I've used both extensively from my Shogun. I can't tell a darned difference in quality between the two. I think once I accidentally selected ProRes, rolled with it, and enjoyed the very same editing and grading experience as I do with DNxHD.

They were tested and are very close. DNXHD seems to have fewer handoff issues between Window and Mac, because Avid made sure the levels stay consistent.

They are both high quality, visually loss less, intra-frame codecs. ProRes is Apple's and DNxHD is AVID's. I do not see any significant difference between them. If you are PC-based, then DNxHD is the way to go. For instance, Da Vinci Resolve on a PC doesn't even give you the option to render out in Pro Res, even though that might be what you shot in.

i've been using xavc-i recently - seems as good as dnxhd - reasons being it 'seems' smoother on the tl, and faster to transcode footage to?

i stand to be corrected if anyone has done tests that prove different....

DNxHD is decoded as 8bits by Vegas, ProRes as 10bits in V14.

xavc-i is also available in 10bit too....

With my Shogun and the GH4 I record in 10bit 422 ProRes always. With Vegas 13 I had to encode that with TEMPGenc to Cineform since that is decoded as 10bit in Vegas (32bit floating point setting).

With Vegas Pro 14 I use ProRes again, since that is now decoded as 10bit in Vegas.

With my FS7 i shoot to XAVC I - decoded in Vegas as 10bit too.

The use of a Shogun with Vegas and DNxDR makes no sense for me - since DNxHR is decoded as 8bit only in Vegas. And the use of a Shogun makes sense only if one records 10bit.

Same as Wolfgang here - but I do see a difference between my Shogun Inferno's DNxHR and my FS7's internal XAVC-I, with the former being obviously better especially in 4K@25p (less so in 4K@50p, but also slightly better). Like most of you, don't find much difference between DNxHR and Prores (the latter perhaps a little bit more noisy) - so I use DNxHR exclusively, even though Resolve would let me grade Prores as well (under Windows). Sorry to say I'm not using Vegas at all :( Just chimed in as I really love this forum, plus I'm looking for some info about positive changes in Vegas - none so far, I'm afraid :(

Wolfgang, it sure makes sense to me, as I'm using it with my A7S 1 to record in 4k as well as slomos in 120fps in full HD. ( and also as an extremely useful monitor, as the small screens are as good as useless ) I also feel that strangely enough, the A7S' XAVC-S isn't all that well digested by Vegas, it feels heavy on the timeline. I know the A7S won't output 10 bit , but for most projects that is of no big concern to me right now.
