slowish navigation

Hello.

I have an AMD 3900X CPU with RX2060 Super and WD black disks and 32Gb ram - however VRD6 seems *very* sluggish to navigate ... f5 and f6 in particular and scrolling with right-arrow-buttons and left-arrow-buttons etc ... and an asdcan on occasion seems slow.

With those PC specs, it should fly along not crawl ?
I seem to recall v5 going faster. edit: no, v5 is currently slower too; I seem to recall it being much faster.

Would choice of Playback Device affect it ?
At the moment it's set to Direct3D11 with smart deint and YUV acceleration is ticked.
Which option should I set ? i.e. which is the fastest. I can't readily locate an explanation of the choices and help does not list them all.

Any advice would be appreciated.

edit: just tried it again and added *very* to the description.

I find that with the top navigation bar that it is fast as it jumps from IDR/ I frame to IDR/I frame.

With the lower fine tuning slider...it decodes the H264 file to find single frames and will always be slower.

In another thread Proxy files were brought up and they would give you fast scrubbing through a file.
VRD does not do proxy files and I imagine that unless the job was a big one the time needed to create a proxy file would negate any time savings in scrubbing through the file.
Having said that... I have never done a proxy file setup. Only read about them.

You mention F5,F6, I believe they jump to scene markers.
I find that the arrow buttons on each side of the "Toggle ad detective scan" button(far right) are better for me to use for this.

Your problem could be file specific and related to the number of frames in a GOP. That can change not only from station to station but also over time as broadcaster change encoders and/or encoder settings. I suggest you look at the distance between I/IDR frames and if it's more than a few seconds that's likely the cause. We've seen GOPs as long as 30+ seconds although typical broadcasts are between 0.5 and 2 seconds. From a broadcaster's perspective, longer GOPs means more time after a channel change before a picture appears.

Looks like you spent money on your CPU, GPU and memory, hoping you mean the WD SDD, not the old HDD "disks"
I also use a 3900X, but with a 1650 Super and 16Gb of memory - my navigation is instantaneous - maybe because I use a 2TB SX8200 NVME SSD for RAW file, temp files and final files.
Windows & applications is on separate Samsung NVME 512GB
As soon as they come out, will be upgrading to a Sabrent Rocket 4 Plus - 7000Mbps Read / 6850Mbps Write of goodness
The bump from my 1650 Super to RX2060 is good for gaming, but does nothing for video encoding - Turing is Turing as far as encoding goes.

Thanks.

I recall looking a year or two ago and long gops 15 to 30 secs was not unusual for Australian broadcasters :( :(

IIRC there was said to be some minor differences in nvenc ASIC encoder functionality between various models (eg NVENC Support Matrix states that there is no HEVC B Frame support on the TU117 ), but I can't locate the table now, perhaps it was heresay ... I also use the gpu for non-VRD simultaneous fast filtering and transcoding as well (with ffmpeg) so it's not wasted ;)
Interactive editing is on the WD black HDD disks; I have a lot of files to store and NVME SDD is prohibitively expensive for the larger sized disks which I use :)
Temp space etc is on a 1Tb NVME Samsung 970 EVO; O/S is on a 512Tb NVME Samsung 970 Pro.
My batch workflow QSFs from a black HDD and outputs to an NVME SDD (temp space is also set to NVME SDD) and then filters/transcodes to a second black HDD which holds lots of final transcodes.

Your right, NVME is still too expensive for huge amounts of storage. I do think you could do better by keeping all your processing on the NVME drives. I start with the initial file on the SX8200, load to VRD, edit and encode back to the SX8200 for the finished file. Only after several files are done, do I batch move them to a WD 10TB Red drive for long term storage and delete the raw initial files from the NVME. I try to keep steps where they will do best. R/W for the VRD encode is fastest off the NVME. Copying GBs of finished data to storage on the HDDs is click&go, then I can free up space on the NVME for more.

Just a suggestion.

I just purchased the upgrade to VideoRedoTV6 and noticed the same problem. Scrubbing video on TV5 is exponentially faster then TV6. I tried the match the video playback settings as much as possible. HW YUV enabled, VRM7, No Deinterlace. I tried various settings on TV6 but all performed the same.

This is a video comparison, same source file, same project using shift arrow to navigate.

Check the options under Tools-Option-Navigation and make sure they're set the same.

You may have Shift set to IFrames in v5 and to One Second in v6.

I looked at your videos but it's not clear how you're navigating. What buttons / keys are you pressing? Doesn't look like you're dragging the mouse along the navigation bar.

Shift right-arrrow and both have the same navigation options set shift arrow move next second.

Are you holding down the shift+right and letting the auto repeat do the navigating or repeatedly pressing the key?

I'm really glad that I found this thread as I've been having exactly the same problem. It's surprisingly annoying :)
I'm quite tempted to downgrade to v5 to see if it becomes more usable again. I assume this is possible?

Best wishes,
Shaun.

Hi, thanks for the speedy reply - I usually hold shift/alt and press the cursor keys repeatedly. There are random jumps as it goes through the file.
It's quite odd to use as the skips feel a bit random ,and not connected to my cursor button hits, which makes it feel awkward to go through a file.

I've not used used v6 very extensively, but noticed this just yesterday while editing an OBS screen recording that I made (VBR mp4). So I haven't investigated this problem in depth. I upgraded from v5 back in september 2020, when I upgraded the hard disk on my PC (an intel i5 4460 with 16GB ram) doing a complete reinstall of Windows 10 Pro.

I should probably uninstall, and try v5 again just to confirm this is the same...

Yes, you should check with V5. OBS typically creates VERY LONG Gops which makes precise navigation quite slow either in V5 or V6.

Yes,
I hold down the Shift-key and the arrow key.

I redid the samples using the same cut sections. You can clearly see that the v6 version is 40s longer to navigate the same cut. My guess is it has something to do with the way v6 handles video rendering compared to v5.
