My guess is most likely the C0001 clip falls outside a SVRT acceptable bitrate margin relative to C0002 and the SVRT stated profile. At that bitrate, many cameras produce clips with variable bitrate. If you just have C0001 and/or C0003 on the timeline, does SVRT suggest a profile and what is the bitrate?

If you have a shared area (Google drive or the like) upload and post a link to those 3 clips and maybe a few users will experiment.

Jeff

Thanks for the bitrate tip Jeff. Unfortunately the files are really large ~1.5Gb.

I checked just using windows explorer:

C0001 = 94019kbps

C0002 = 97926kbps

C0003 = 94917kbps

And yes as you suspected, using PD15 indeed C0001 and C0003 clips do work together for SVRT, but not with C0002.

I am quite "stumped" now because all I am after is a simple editor that allows me to glue different videos together (with some clip trimming) without re-rendering.

I had also bought Corel VSP X9 but that also did not work (no support for 100Mbps, only 60Mbps max so it re-rendered everything).

Does anyone have any suggestions what to do next or what package I should be getting (especially for Sony XAVC-S "100Mbps" 4K files)?

Maybe the PD developers would open up their bitrate margin?

Thanks!

Just a hunch. I don’t have 4K 29.97fps 100Mbps XAVC-S video to test out. Maybe create a custom profile of it using a lower average bit rate but a higher max bit rate to try out for svrt.

What I'd do is define a profile with the avg bitrate of or your 3 files assuming these are representative, remember to just use the video bitrate, and then you will have to edit the profile.ini at C:\Users\username\AppData\Roaming\CyberLink\PowerDirector\15.0\UserConfigure\ and set a slightly larger range for <Min BitRate>xxxxxx<Max BitRate>yyyyyy in the profile.ini file for your created profile. Only edit profile.ini with a true text editor so you don’t had any unique formatting characters. Simply try and see if it works.

Also be sure to use the latest PD15 release.

I realize the files would be large, that’s why I suggested a Goggle drive.

Hi Kenster -

I'm interested in this because I've noticed the same thing with UHD clips shot on Sony RX10 Mkiii - similar recording options - http://www.imaging-resource.com/cameras/sony/rx10-iii/vs/sony/rx100-v/specifications

In PDR15, whether I've shot at 60 or 100 Mbps, I get the same thing Kenster posted when using "View SVRT Information". PDR finds a profile in Produce > Intelligent SVRT, but some clips have to be re-rendered.

As Jeff pointed out, the VBR is variable. One clip (shot at 100Mbps) I checked in Bitrate Viewer ranged from 89-105Mbps. That may be what's causing the issue.

When I first started using the camera, I made custom profiles to match the UHD clips - one for 60 & one for 100Mpbs. Oddly, even if a project only has 60Mbps clips PDR selects the 100Mbps profile in Produce > Intelligent SVRT. If I delete the Profile.ini so PDR has to generate a fresh one, it suggests a profile with ~60Mbps bitrate. BTW it gives it a Min Bitrate of >0< (same for the 100Mbps test).

Jeff - I tried your suggestion above (expanding the range between min/max BR), but I haven't tricked it into working yet. I still, invariably get some clips showing "Video Rendering Required".

Sorry, I don't have any useful suggestion. Just confirming what you've found.

Cheers - Tony

Hi all,

Thanks for all your inputs. Unfortunately editing profile.ini did not work (as Tony also noted).

I am noticing the following:

• SVRT ignores whatever profile I choose (or even the profile it "finds" from the custom lists).

• It selects the "most similar" clips that take up the majority of the timeline, then re-render all the rest to whatever the bitrate these "most similar" clips are. Eg. If I made C0002 which took up the majority of the timeline shorter in duration (s it would no longer be the majority of the timeline), it would then re-render this (rather than C0001 and C0003 which when combined are now longer).

Anyway, I will continue to play...if anyone has any ideas do post them.

Thanks and cheers!

Essentially that's the correct behavior of SVRT when the clips are identified as not being consistent in details which I still think is maybe the underlying issue. I think this is something CL will probably have to resolve and more than likely the only way to do that is get some problematic clips to them. Back in the day we even had to do that with basic 24Mbps Canon footage as SVRT had similar issues. A few users muddled around but we never really got anyware, CL ending up correcting SVRT engine, http://forum.cyberlink.com/forum/posts/list/18137.page#post_box_93127

I don't see anything in the SVRT help that would indicate it's outside intended SVRT capability. The XVAC S is really just a high level H.264.

Jeff

I think Jeff is right - as far as I can see there's no way of resolving it within PDR15.

I've uploaded some clips for testing, each ~10 sec in duration.

There are two shot at 100Mbps on the RX10iii

and two shot at 60Mbps:

The clips are straight of the camera, even though I renamed them for identification.

Why is there no problem in Play Memories Home ???

30 clips from a RX10 III are put together in less than 2 minutes !!! Without problems with different bit rates.

In the PowerDirector 15, a lot has to be done

Quote: Why is there no problem in Play Memories Home ???

Because it simply works as it should for the "Combine Videos" feature, as typically does ffmpeg and other tools. I think the OP question was related to any suggestions getting SVRT to work with PD15. My view it's simply something CL needs to correct with their SVRT TrueVelocity engine.

Yes, ynotfish, Kenster, others could always use the free Play Memories to combine prior to editing in PD15. More than likely, always be faster as well since PD15 always re-encodes clip ends while other tools don't.

Hi Karl01 -

I put your suggestion to the test. I'd never bothered with Play Memories, so I may not be using it in the best way possible... BUT

I took 27 clips from the RX10iii & tried to use the "Combine Videos" function. It rejected some because they were different formats/codecs. It rejected others because they had different frame rates, so I was left with 18.

I carried on with the "Combine Videos" process. Play Memories took a little more than 4 minutes to produce a combined video... BUT:

• The video wouldn't play in MPC, VLC or GOM Player


• MediaInfo could not even interpret its properties


• It could not be imported into PDR

That whole process took 10 minutes or so, which I would consider a complete waste. I did a screen capture of all that if you'd like to check where I went wrong.

Revision to above:

Using Play Memories, I have managed to produce something "readable". I know it's beside the point, because the OP asked about SVRT in PDR.

Jeff's assessment is right.

Hi everyone,

Just to say I have also highlighted this SVRT behaviour with the Sony XAVC-S clips/provided the thread to Cyberlink techsupport and a refinement of SVRT will be released in the coming beta patch!

Btw just to confirm with the more experienced folk with PD, is this the link for watching for patches: https://www.cyberlink.com/support/powerdirector-ultra/patches_en_US.html

(seems to be official patches and not "betas")

Anyway, here is a snippet of the answer:

=====

Regarding your concern, I would like to inform you that we received the response from our R&D team and they are informing that according to the provided source video, the SVRT doesn't work in certain combination is due to the actual bitrate of the source video are out of the tolerated range. For example, when putting a 60MBps bitrate video with a 100Mbps bitrate video in a same project, PowerDirector would analyse the video in the timeline and use the video in the front as the reference to decide the SVRT profile. That means when the video bitrate is out of tolerated range, SVRT would not be applied on the video.We appreciate for hightlighting the issue and will refine the software behavior to decide SVRT profile to use. Once we complete the test, the refined behavior would be released with the coming beta patch in forum.

=====

Fingers crossed and hoping this will sort it...
