Question

Premiere 4K Proxy to HD Monitor via Intensity Pro

I've already posted this to the Blackmagic Post Production forum, but thought I'd try here as well.

I'm working with RED 4K footage. I have imported it and would like to create HD proxies that will play on my HD monitor via my Intensity Pro 4K. this seems like it should be simple, but so far, I can successfully make proxies that play on my computer monitors, but not on the one linked via Intensity. I do not have trouble playing other media on my Intensity monitor.

Here's what I've done:

1. Imported the 4K .R3D clips into Premiere. These appear fine, but are too much for my system to play back happily.

2. Created proxies. I chose from the pulldown menu, "1280x720 Apple ProRes 422 Proxy." This created Attached proxies that play back fine on my computer monitors. But they do not appear on my Intensity connected monitor.

3. I also tried creating proxies using 1280x720 GoPro Cineform. Also, no luck.

I am betting this is a fairly simple issue, but I'm having no luck so far. Anyone have any pointers for me?

    I may have an answer for you  (I have a pre 4k Intensity card).

    Intensity pro 4k can feed the below signals to your tv.

    SD Video Standards

    525i59.94 NTSC, 625i50 PAL

    HD Video Standards

    720p50, 720p59.94, 720p60 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94, 1080p60 1080i50, 1080i59.94, 1080i60

    Ultra HD Video Standards

    2160p23.98, 2160p24, 2160p25, 2160p29.97, 2160p30

    If you are using an BM Ultra HD Video project (a 4k project/sequence) and sending that signal out through a BM card to a HD 1080p only tv, you won't see anything.

    Try

    HD Video Standards

    720p50, 720p59.94, 720p60 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94, 1080p60 1080i50, 1080i59.94, 1080i60

    Which HD standard will depend on FPS of your 4k material.

    See if any of these work.  You may have to scale your 4k material to fit the frame size your tv is capable of viewing.

    I had a tv/monitor once that would not play 1080p23.98 signal (eventually I got rid of it).  It would play 1080i59.94 or 720p23.98.  Your tv may have the same issue with a 4k BM sequence. If that is what you are using.

    I had project with red r3d 4k content and I needed 1080p23.98 output.  My work around till I got a new monitor was to edit in a BM 720p (720p23.98) sequence.  This allowed me to view the material through the BM card to my monitor. When I was done I copied and pasted to a 1080p23.98 sequence. Scaled footage as needed (not viewing through the BM card). Then off to adobe media encoder.

    Worked like a charm for me. Though, I'm not doing broadcast/feature work. 

    Of course if you are doing broadcast/feature work, get a better monitor.

    ;-)

    Good luck!

    Thanks all for these helpful suggestions. I have been away from my computer all day and will try these ideas tomorrow.

    First, a Correction: I mistakenly reported the size of my source footage at the beginning of this thread. I am working with RED 5K footage, not 4K.

    I've been off this project for a while, but I now have a mostly successful workflow and feel I should share in case someone else—or I, after I've forgotten—needs the answer to this very specific issue. I also feel I owe a follow-up to everyone that generously contributed suggestions that got me there — most of your replies deserve at least a partial "Correct Answer."

    Despite, the original subject line, this really became an issue for me of how to get the image to my outboard TV and just how to get fluid playback on any of my monitors, given my under-powered gear. Here's what's working. I'll be as concise as I can manage (which is rarely all that). I'll skip how to do some of the basic tasks like importing and creating proxies. And, again, my source material is RED 5K and my system specs can be found after my signature below.

    1. I imported my clips.
    2. I created proxies. I chose 1280 x 720 Apple ProRes 422 from the pulldown menu.
    3. I created a sequence setting that works in my system: 1920 x 1080p, 23.976 fps and everything else default. Here's a frame grab:
    4. I went to Preferences/Playback/Video Device/Black Magic Playback Setup. I made sure Intensity Pro 4K was chosen as Device and, because my proxies are 1280 x 720 and I'm working with a 1920 x 1080 sequence, under For output of unsupported frame sizes, I chose Scale up.
    5. ​Making sure the ​Toggle Proxies ​buttonis on, I start cutting.
    6. Because the source footage is larger than the sequence settings everything is extremely cropped. To fix this, I choose Scale to Frame Size. I would typically prefer Set to Frame Size for its flexibility, but, for some reason, for fluid playback, I have to render before playing back with Set and Scale plays fine without rendering.

    And that gives me a more or less usable workflow. I still don't get a fluid playback on the Source side regardless of whether the Toggle Proxies button is on and Source also doesn't play on my outboard TV. But, geez, what do I want, eggs in my beer?

    Of course, I now don't have an exportable 5K sequence. I addressed this in another thread, but a here's a quick executive summary of what I've worked out for that:

    1. Upon picture lock, I copied the contents of my sequence.
    2. Created a new sequence with settings that match my full rez footage:
    3. …and pasted my picture lock into it. I think this is now a perfectly suitable 5K sequence ready for export.

    I appreciate that no one may make it through this late, wordy and extremely system-specific response, but should that happen and you find flaws in my process or conclusions (especially in regard to my export expectations), I would be thrilled to hear back.

    Thank you all for your help and your patience.

    good going... you made nice headway as shown in your screenshots.

    I don't know why my google search showed your card as limited to 1080p, but I guess it didn't see the 4k iteration.

    Anyway, so far so good.. now maybe some minor settings will get you exactly squared away !

    one of the first things you will notice is that your Blackmagic card is limited to full HD... since you are now trying to use 4k, that is a bit out of range for the Blackmagic card to handle.... so that's one thing...

    ???? might have a bearing on this case ??

    If you transcode the 4k to full HD BEFORE importing to PPro, you may be able to avoid a lot of uncertainty regarding 'proxies' and proxy settings and what the PPro program is trying to ACCESS for playback etc..

    lots of variables and crazy stuff !

    But the proxies depict 1280x720 so that's well within HD range (and, though it's not relevant here, I've got the Blackmagic Intensity Pro 4K, so it should be able to handle 4K — my TV, however is only HD).

    Then I would need to come up with a workflow that would allow me to link to the 4K files at the end of the edit. With proxies that's relatively easy, but I would think it would be much harder, if not entirely manual, if I transcoded first.

    This will take a while for you to explore all available options to get around the problem.. and it will get complicated. Sorry.

    I have also been through the same stuff over the years, and it took me ( cause I'm an idiot ) a really long time to finally get it right for my own editing computer ( nicknamed THE PIG in honor of the Empress of Blanding's Castle … a prize winning pig ).

    You have a TV hooked up.. not a computer monitor or a video monitor.

    However, there may be a way to somehow work through that to get the signal there.  It won't be color correct or nothing, but should be somewhere around rec 709 or sRGB or something similar... maybe with adjustments you can match it to your primary monitor color and move along with some semblance of comfort that what you 'see' is what you get when you export.

    This would probably entail some complicated stuff...

    hehe, sorry , but that's life.

    Unfortunately, the situation is not as simple as it should be. Just to get things moving along... I'll ask some simple questions though....

    what is the monitor you are using from your HDMI output of intensity pro card.. which I assume you plugged into some pci e x 8 version 3 slot ??

    need to know if it's just another monitor or a VIDEO monitor...

    after that... when you installed the black magic software and drivers ( the latest ones instead of the little thing that came with card ) .. did you use 'blackmagic' settings when you started new project ???   There would be a bunch of Blackmagic OPTIONS to create a new project ... when you start a new project …

    Hmm, more difficult to answer. I've— Wait! That helped. But I'll back up.

    I've had this card for nearly three years. I've updated the driver periodically; currently I'm running 10.11.4. Typically, I haven't needed to play with settings when I start a new project. But, that question made a lot of sense so (and I'm going to put a lot of detail in here so someone else with the same problem or—as it has happened before—I after I've forgotten the answer, can work their way through) I went to Premiere/Preferences/Playback, confirmed that Blackmagic playback was checked under Video Device and clicked on Setup.

    And, lo and behold, under For output of unsupported frame sizes, I had No Output selected. Switching it to Scale up (since my proxies, at 1280x720 are smaller than my TV's native 1920x1080) put the image on my TV.

    So far, so good. But, having resolved that first issue, I am still having related troubles. These should possibly be part a new thread, but, since I have your attention, I'll see how far your good nature goes.

    Playback is still extremely stilted. Though my Mac is very old, I typically can play full HD without trouble even on long, complex edits. Not so with these proxies. And when I tried rendering the sequence (which, so far, is a single clip), it became extremely blurred on both my TV monitor and my computer monitors. I've attached rendered and unrendered, but oddly, when I used Premiere's Export Frame to create the rendered image, it wasn't blurry at all. The image I am providing is a frame grab instead.

    Any more clues Rodney or anyone else?
