"Reference window", on premiere, don't play video well when ganged to "program window"

Hi!

I started a multicam project, on Premiere Pro CC 2020.

Everything is fine, no problem playing all cams, one output (with a blackmagic) and premiere generating muticam view with program. Every video generated rolls just fine without any problem.

To the director see the multicam cams in a better way, I moved the "program window" to a second monitor with multicam mode and put the "reference window", on top of timeline (on main monitor), ganged to program. When I did this, the playout of all signals start well but in a few seconds the video on "reference window" goes to delay (not sync) and dont appear a smooth/fine image ("dragged video").

I tryied to reduce the quality of playback and same thing.

The performace of the PC is soberb and no problem playing out all the cams and outputs without the "reference window".

My question is if someone experienced this situation and how to solve this problem.

I dont know if, may be, this is a bug, or I´m doing something wrong.

Thank you

but it works for me using proxies. granted I can't do a camera switch while playing. but playback is fine. If you need to use this setup, might be worth a shot to generate proxies. I am working on a 2009 macpro with a usb3 card to connect to a media drive. That's an old machine and can't imagine it compares to what your machine can do.

I will try proxie mode to see if that solve the problem with the configuration I mencioned.

Until then, I disabled the reference monitor and I´m editing in "normal mode" with the "program window".

Thank You.

Hi again!

I try to make some proxys from my original footage but no success with MP4.

My original footage (Mov files with MPeg 4:2:2 from Tricaster 8000) seems to be not a suitable codec to premiere.

Always get error saying something like the proxy has always something different from original. I tryid same number of audio channels (mono/stereo) as no success.

I remember something i did before with Mpeg 4:2:2 clips (mpeg native - newtek) recorded with tricaster, that always have to convert to another codec because premiere took to much time to synchronize in play/pause action. I worked always with SD clips converted to MXF IMX50 PAL (mpeg codec) and multicam was just fine.

In this project I'm working with HD clips and remeber to convert to MXF HD 4:2:2 and associate them to the originals like a proxy. By this way everything is fine, even with reference monitor ganged to program. All sync and well! Once again there are some codecs that premiere dont like so much and MXF is a good one.

Thanks for all your replies.

yes, it plays fine, but when I click on a different camera in the program monitor the edit happens in the timeline but is not reflected in the reference monitor. If I go back and play that section, the correct edit appears in the reference monitor.

In my case I dont need to switch cameras on the fly because have a reference clip.

Just doing playout with that configuration a few seconds ago, withou any action or edit point, "reference monitor window" goes "choppy" with some "light strob" and sync (audio/video) is lost.

I also tryied various timeline settings with different codecs and video previews.

Dont understand why it happens...

Also tryied with smaller project and same happens.

I did a test and put the system generating 10 signals in multicam (9 cams and a final PGM) with program (on premiere "program window") and 2 final outputs with blackmagic (1 CRT for reference and 1 LCD) and everything runs perfect.

So, the computer shows 13 different videos and GPU is only 60% and memory 50% usage with CPU 16 cores with low utilization.

So this PC have a soberb performance and already proove that, so I think there is some problem with this "reference monitor windows".

CPU: Intel I9 9900K (16 cores)

RAM: 64 GB

GPU: NVIDIA RTX 2880Ti 11GB

5 SSD (high performance)

1 HDD (High performance)

Once again, thank you for replying my posts.

sorry, I meant the wrench on the bottom right of the program monitor...

when you playout timeline I supposed that that you see all cameras rolling and "reference window" rolling too with final program. So do the playout in timeline Iand confirm everything is fine on "reference window".

so if I drag the program monitor to the second window, click on the settings wrench at the bottom left of the program monitor and switch to multicamera so I just see the 3 camera views, open the reference monitor and gang to program monitor, if I play the program monitor and click on one of the cameras, the reference monitor does not reflect the switch but it is recorded in the timeline. Is there a setting I'm missing?

Take a look at this photo. Is that what you're trying to do? cause it works fine on my system working with proxies. I'm pretty sure the source material was h264 (shot on canon cameras) 1080 24p. And the proxies were with the same pixel dimensions prores proxy.

Using your picture as reference, in right monitor I have "program window" as you, but without program video, only multicam. In the left monitor I have "reference window" with option "gang to program" to follow multicam playout (and other windows like timeline and project).

In my case, "reference window" is a "final program video" to maintain cameras alone in just one monitor.

Try to select the "gang to program" on "reference monitor" using that configuration an let me know if you see something anormal in "reference windows" during continuos playout.

I guess I don't understand why you're working this way. What are you seeing that you wouldn't be seeing in the way I described that you say works fine...? (man that's a confusing sentence, hopefully you can figure it out).

you might find using a proxy workflow more dependable particularly with a multicamera timeline. You don't tell us what format your source video is (codec, frame rate, pixel dimensions). I'm not sure exactly how you are setting up your workspace. I have a blackmagic intensity pro card in my mac pro and I have that feeding my program to a second monitor. the main monitor I have a workspace set up for multicamera work with the program monitor which includes the multicamera view (if that's the right term) expanded to the left as far as it will go since I don't really need the source monitor while doing my "switch." I have a different workspace I can quickly switch to if I need to edit from other sources or adjust effects.

If I do like you describe I have no problems, everything plays well and sync.

My problem is using "reference windows" ganged to program.

I'm using QuickTime HD clips 1080i PAL (recorded on Tricaster 8000 from Newtek) with SSD and no problem at all playing videos, multicam, program or outputs.

The problem is when activate "reference window".

When activated premiere dont work well and I dont know why...
