I recently bought a ninja to use with nikon d800 ...hdmi output (uncompressed output 1080p ) to ninja, saving as pro res or avid codec... ( my choice for me is avid for pc )...
That gives me a 10 bit 422 space instead of the 420 8 bit space, and also the bitrate is higher on the ninja recording ( mov with avid codec out of ninja SSD ).
the advantages are : 10 bit space with high bitrate capture and any color correction and effects etc done in editing will be in the space for " editing" rather than a file used for delivery ( viewing ).
Also, I dont get the stress on the cpu etc. that the h264 puts on the computer.
there is no advantage to editing the original stuff in this case..in fact is the opposite...
It is similar to using log c from a card on the alexa or using 2 HD SDI bnc outputs to get the 444 to a recorder outside the camera... know what I mean ??
There is no question that Prores gives you a better file to edit and grade with if you have that choice at acquisition. But, if you already have H.264s as your source files, there aren't any good reasons to transcode to edit in Premiere. (unless you have under-specd hardware)
You won't gain back any color space or remove compression artifacts by moving H.264s to ProRes, you will just lose time and HDD space. I too used to edit in FCP and had to transcode, and the ability to bypass that step is one big reason I came over to Premiere. Version 5.5 on the Mac didn't give me good playback results, but CS6 and beyond have played the H.264s just as smoothly as ProRes. It is more CPU intensive, so having a decent machine is necessary.
If you find that you are getting realy choppy playback, you can try to drop the playback resolution (although with H.264s that sometimes can't help) and if you are still getting trouble, then I would do the transcodes.
So, in summary, you don't lose anything by editing in H.264 and you gain time and HD space.
There is no question that Prores gives you a better file to edit and grade with if you have that choice at acquisition
thats the trade off... the compression and space on HD or cards etc... and the actual 'space' you work with in editor,.. and how the final product you deliver comes out after adding effects and cc etc...
So its " time " ( transcode to editing format vs delivery h264 ) , plus your own edit and cc , and the final product quality... IMO just because " it works " ( you can edit h264 native ) does NOT mean you get the best out of your workflow...
to each his own, but at least you should know 'why' you make the decisions you MAKE.
if your final product is web delivery of pretty simple source material ... go for it... its all a matter of balance, quality and space and whatever...good luck !
Cool, I understand. We delivery stickly for the web and normally don't go crazy with color correction.
You guy mention that Prores has better color space and is better for adding effects etc. But the footage is compression in camera to h264, so I wouldn't be able to regain any of that through converting to Prores..correct? That wouldn't make sense, you can't really upres footage that way..
I havent done a side by side 'test' but with the ninja off the nikon my first impression has been that the quality of the video is BETTER than from the card ( avid 422 instead of h264 off card ). Its probably due to the bit rate ... to me it looks nicer...but its not EARTH SHATTERING... like its just subtle..if that makes any sense...??
I dont know if you'd see the same thing in a transcode, cause the ninja actually captures at a faster rate off the hdmi.. its not just a transcode...
good luck !
Aside from saving HDD space and time encoding, are there any other technical diffirences?
"Inside Premiere Pro, the images will stay exactly as they were recorded in-camera for cuts-only edits. If there’s no color work going on, the 4:2:0 values remain untouched. If I need to do some color grading, Premiere Pro will, on-the-fly, upsample the footage to 4:4:4, and it does this very well, and in a lot of cases, in real-time.
Going to a 4:4:4 intermediate codec does have some benefits – in the transcode process, upsampling every frame to 4:4:4 means that your CPU doesn’t have as much work to do, and may give you better performance on older systems, but there’s a huge time penalty in transcoding. And, it doesn’t get you any “better color” than going native. Whether you upsample prior to editing or do it on-the-fly in Premiere Pro, the color info was already lost in the camera.
In fact, I could argue that Premiere Pro is the better solution for certain types of editing because we leave the color samples alone when possible. If the edit is re-encoded to a 4:2:0 format, [such as DVD, Blu-ray or Broadcast] Premiere Pro can use the original color samples and pass those along to the encoder in certain circumstances. Upsampling and downsampling can cause errors, since the encoder can’t tell the difference between the original color samples and the rebuilt, averaged ones."
I just want to chime in after spending all my sunday deciding whether to transcode to prores or not with the new Premiere CC on a documentary I just shot.
Decision...I'm transcoding to Prores 422HQ.
Scrubbing and moving around in the timeline made things so much nicer. My CPU bars went full throttle with H.264 footage. With Prores it was like silk moving through clips, CPU bars had no effect. Also slightly faster rendering.
I'm about to spend a month cutting this Doc and 12 webisodes. Harddrives are cheap, I will transcode overnight. I based my decision on ease of use for THE LONG TERM.
If I shot an event during the day and needed a cut by nightfall I would not transcode.
Hope this helps:)
