SpeedGrade 2015 keyframe issue

[Soileau Photo and Video]

Hi there. Not sure if anyone here is still using SpeedGrade, but I recently downloaded it from an old download link I found on the web that I guess Adobe hasn't tracked down yet. While installing, it said a license was found when I signed in with my current CC account, and it installed normally. It also shows up in the Creative Cloud app as CC 2015, so everything is installed properly - no cracks were used. I'm having a seemingly bug related issue with keyframing, however. As soon as I set a keyframe the video is completely destroyed from that frame to the end of the video. Before that frame however, there is no damage. I've attactched some images to demonstrate. I'm using CC 2015 9.0 so I'm not sure if this is something that was fixed in 9.0.1 or 9.1. I can't find any download links for the 9.0.1 patch, but I did find one for 9.1. However SpeedGrade wouldn't launcg past the splash screen after installing, so I had to reinstall 9.0. Just wandering if anyone is still familiar with this software and/or has experienced this issue before. It's a really great piece of software that I'd like to continue to use as you have significantly more control over the image than with Lumetri.

Hey Neil, might you be able to field this one?

Yup, Kevin ... I'll take a look ...

I've still got Sg loaded on my "old" main computer, now the backup. Use it occasionally as well, it's still got some darn useful abilities.

But I'm still not completely back up running from moving out of the building we'd had our business in for 40+ years, including my backup machine is still not setup. That said ... this type of thing is often a GPU issue.

So what's your GPU and what driver are you using? May or may not be an issue.

Second, what created the media? That's showing as mp4 ... is it long-GOP? One thing I did occasionally with Sg if a clip had issues was t-code it to Cineform, which Sg loved.

Thanks for the reply. My GPU is an RTX 3050TI mobile (4GB) with what NVIDIA says is the latest studio driver. I can't seem to find any info on whether my camera (Canon EOS R8) shoots long gop or all-intra. FYI this was direct linked from Premiere 2015. I was able to do 99% of my grading for this project in SpeedGrade without an issue so I just did this one key frame job in Lumetri afterwards. I'd still like to get to the bottom of it for moving forward, though.

On this Canon page, they have multiple places saying "click here for full details pdf" and if you scroll down, you do get to all the video details ... which you really should peruse.

That camera has two levels of long-GOP H.264/5, they just call something like normal and light. Light of course is lower bitrates. You could shoot a short clip in each, drag a clip onto the MediaInfo icon on your desktop, and see what the data is for i/p/b frame usage.

It also can do All-I ... all i-frame ... which uses H.264 compression process except there's no p or b "frames" ... only complete, compressed frames. So the data rate recorded is much higher, but it processes in the computer as if say ProRes.

And it can do Canon Log-3.

The issue with the keyframe is ... intriguging.
