Edius Suddenly Acting Bizarre -- Jerky Playback in Overlay and Audio Drift

[edver1]

Thank You all for the advice.

[edver1]

I would advice to get 2 Dell 27" 2560x1440 and they work fine at 100% scaling

End this week or next,I will receive the Dell UP2716D monitors,if the output isn't smooth enough,would the BM intensity pro 4K card a good choice ?

Video playback on in the Edius GUI is not perfect, probably due to the differences in refresh rates from a computer monitor versus video framerate (computer monitors usually start at 60Hz and go up from there. If your video framerate doesn't evenly divide into the refresh rate of the monitor, it will often look a little jerky. Additionally, computer monitors and video are often in different colour spaces/models, RGB vs. YUV, so you can't really critically evaluate video colour on a computer monitor).

If you want to critically see what your video is actually looking like, it is advisable to use a video output card or box and a video monitor, so that the frame rate and refresh rate are in sync or evenly divisible, and in the same colour space. This holds true for every NLE on the market.

That said, the BM Intensity Pro 4K is an acceptable entry level card for HDMI output connections to a video monitor or TV, but if you need a different type connection, such as SDI, or if you plan on capturing analog video with the card, you would be better off looking at one of their Decklink cards. AJA also make some nice cards, but they tend to be more expensive, and originally you could not capture with them in Edius, but this may have changed.

Recording isnt on my list,Ïll triyng to match the framerate as much as posible of the recorded files.
My plan is to set one monitor in the colour space same as the camera an the other like the screens I play them
All this as much as posible.
An Aja card is above my budget .
Thanks for the info.

the Dell Monitors are for PC graphics and not for viewing video

so connect a proper TV to a BM4k Mini Monitor card

there are also a few Grass Valley cards you may still be able to buy like:

STORM Pro with Bay

STORM 3G or STORM MOBILE

I'll say it again:

You may not be able to adjust a computer monitor to be evenly divisible by your framerate. For example, if your video is 50p, 50Hz is normally not a valid refresh, and you may not be able to pick 100Hz, 150Hz, 200Hz etc. Also as I said, computer monitors operate in RGB, while most video is in YUV. This is not something that is normally changeable on a computer monitor. Colours are often close, but not exact.

I prefer the Intensity Pro 4K as an entry level option for the analog audio output. With the mini monitor, you need to listen to the TV, take audio out of the tv to speakers, or pass the hdmi through a de-embedder or de-embedding amp before hitting the tv.

My sony video monitor is fast enough to not notice any latency relative to audio, so the BM IP4K worked ok, but on a lot of consumer tv's, the display has a more noticeable delay processing the video relative to the audio if the audio is monitored before the tv. If I was using a TV, I'd really want a de-embedding amp with some delay compensation to adjust for the tv latency, but with the monitor I have, I can just feed audio from the I/O box through a level control to a set of powered near field audio monitors.

I am not advocating one way over the other, but these are points that you need to be aware of if you are trying to set up a proper monitoring environment.

if you go from BM HDMI out to a Home Amp (such as Yamaha) and from home Amp to TV, you will have perfect audio and lip sync

set the default sound device to BM and you will also hear all PC sounds via the Home Amp

if using analog audio from BM IP4k, I would then use component out to TV to maintain lip sync, because HDMI usually has a 40ms delay

I realize TV's and monitors have a different "goal" and the basic techniques are
not the same,but with a good calibration tool you should get a decent similar picture ( not professional use of course ) or not ?

the Dell mon will run at 60 hertz and when playing Pal video which is ideal for 50 hertz, you will get jerky results and horizontal tear lines especially during camera pans

TVs in your country are 50 hertz, same as here in Australia

also, PC mon work in RGB, not ideal for video

Thanks Anton for re-enforcing my points.

As I have stated twice before and Anton has re-enforced and re-phrased again now, framerate vs. refresh rate differences will make the video motion look bad. RGB vs YUV will make video colours inaccurate.

Calibration will get colours close, but not exact and will do nothing for the framerate/refresh issue.
