Hi,
Mechanical trim (by hitting 1 frame or 10 frames increments) lag have been much improved for some time now, it still lags a bit compare to software only but that’s the case with any IO, even mojo DX and nitris DX. Same goes with the performance in color correction mode. Those were the two main issues, now we’re just left with the 3 I mentioned: 1 frame jump ahead, reverse playback and mouse shuttle. If Avid and BMD get their act together and solve those we will have a solid IO solution line at affordable price…

That’s where I’m getting at. Since Avid and BMD are partnering on this can we expect improvements on all BMD hardware line? I have access to ultrastudio and deckling cards but since desktop video 10.5 that brings support to the DNXIO is useless with MC coupled with other BMD boxes I just can’t figure it out on my end, that’s why I’m asking for feedback.

Having frame accurate and reliable playback should not be too much to ask for an editor. Ultimately editing is about hitting the right frame to make a cut! I set all my outpoints dynamicly and got used to correct the one frame jump ahead manually when I’m on BMD hardware but the reverse playback stuttering is distracting and makes me miss my intended trim points to often.. Mouse shuttle is a huge time saver when listening to interviews and is basically unusable on BMD boxes, that all makes for an unpleasant experience at best and needs to be addressed… I can’t imagine Avid having their official IO exhibiting such behavior when its strength has always been no dropped frames and smooth playback with perfect audio sync, as long as you transcode of course.

Hi,
I’m also curious about the playback performance of the DNXIO, hardware playback acceleration as with the Nitris DX would be great if implemented one day thru software update but first things first… Do we a least get better playback than with other Blacmagic boxes! Each setup with Media composer 8.x and a Blackmagic box attached that I’ve worked on had the exact same annoying playback issues or limitations.

-When stopping playback in source/record mode or during a dynamic trim, there’s a one frame jump ahead that occurs. Playback stops accurately and a fraction of a second later jumps one frame ahead.

-When engaging reverse playback (J) in any mode the first few frames are very choppy, playback gets stable only after a second or so.

-In mouse shuttle mode when changing the playback rate to listen faster to interviews things becomes really unstable.

None of this happens on DX or Aja hardware so it’s definitely the implementation of BMD drivers and Open IO.

Thanks for sharing your experience,
Nico

Thanks Joe,
I always keep a clone of my system at hand so that doesn’t scare me too much 😉 So playback is really on pair with DX hardware on AJA boxes, that’s really good news. I don’t see how it can mess with the system to the point of needing a clean install thought! That’s uncommon, are you positive the AJA box and drivers are to blame for that? Anyways thank you so much for your feedback, I’ll give it a try with the Ttap…
Best,
Nico

Hi Joe,
I’m recently using blackmagic ultrastudio express on a laptop set up with media composer and experience the same one frame jump when stopping playback that you mentioned. I also get a weird jump when starting a reverse playback (J), a second later reverse playback becomes stable. Last but not least, playback gets very choppy when I enter mouse shuttle mode and start playing with the playback speed, a feature very useful when you want to listen interviews at a faster playback rate to save some time…
So far those are my only complains with the BM box but it really makes a difference compared to my office set up with DX hardware. Can you confirm that none of this happens when using an AJA box? I went with BM for Resolve compatibility but if getting a T-Tap just for media composer monitoring solves those playback issues I’m sold. I don’t feel like waiting and hoping for better drivers, even thought your right, things might get better with the DNxIO partnership…
Thanks,
Nico
