Quote Hi,

I'm learning SVRT and I discovered that I'm unable to select the SVRT after I went through the profile analyzer in Produce.

(Pls see the attached video: https://drive.google.com/file/d/1XbszwMgX8FixO_zUGMOEUfwpzTD7BDWP/view?usp=sharing)


Why is this so??? Any solution pls?

You have a mix of images and video on your timeline, and SVRT only works when you select an ouput profile that's essentially identical to at least one video clip. You have the SVRT track enabled above the timeline, and it's solid red, which means SVRT is not applicable.

When you used the Profile Analyzer, you used the Best Matched Format tool and it showed only minor workload reductions. The appropriate tool for determining the best SVRT profile is the tab to the right of BMF, which is Intelligent SVRT. If PD has or can create a matching profile, that's the easiest way to get there.

Remember that all of your images and any video clips that were created with a different frame rate, bitrate or compression than the one that SVRT is geared to will require CPU rendering. No GPU hardware encoding or previewing is available when producing with SVRT.

Hi optodata,

I understand now. If it shows SVRT track in red colour means SVRT option in Produce cannot be selected.

Also the Intelligent SVRT is actually the Intel Quick Sync Video option, am I right to say this?

No, the second part is not quite correct.

IF there is a profile that will allow PD to use SVRT, it will show up when you run the Intelligent SVRT tool, and you'll see a significant amount of green if you go back to the Edit page and look at the SVRT track.

If there is NO SVRT profile for your timeline content, the SVRT track will be shown as red. End of SVRT story.

The other producing option is whether to use Fast video render technology or not.

When that is selected and SVRT is not available, in your case that means you're telling PD to produce the project using Intel QuickSync. People with different hardware configurations will see nVidia or AMD hardware encoding options.

If you deselect the Fast box, that means you're telling PD to produce using only your CPU. No hardware encoding is done at all. This option is typically the slowest, but it's useful if the quality of the produced video suffers when using hardware encoding. Think "getting it done quickly" vs. "getting it done right."

Most of the time, having the Fast box checked is the best choice, and when SVRT is available, that's by far the fastest way produce a finished video. Using QuickSync/nVidia/AMD hardware encoding is usually the right call when you need to fully produce a project.

Generally speaking, you'd only want to uncheck the box if you saw problems in the finished video, like blocky-looking sections or transitions that didn't flow smoothly. Using the CPU should give you a smoother output, but with increased time needed to produce the video.

Hi optodata ,

I suppose I know what u mean so pls let me confirm with u again.

SVRT is for producing videos in a fast way. If your SVRT track is in red, SVRT is not needed. If it's in green, then you can select SVRT option.

It's best not to use hardware encoding/ hardware acceleration as it affects video quality. U mentioned do things fast, quality will be affected badly so it's best to produce videos in a normal way (the speed which CPU is using)

Am I right to say all these?

Hi Leo

Thanks for letting me you how you've interpreted my comments. I tried to provide as complete a description as possible, including discussing some very subtle differences as to when someone might prefer to use one method over the other, but I'm afraid what I've actually done is given you the wrong impressions of PD's capabilities


First, please have a look at Cyberlink's description of SVRT. That's the core of what it does and under what conditions it will and won't be available.

Now, let me reword your first statement so that it conveys the situation more accurately:

SVRT is for producing videos in a fast way. If your SVRT track is in red, SVRT is not available, and cannot be used. If it's in green, then you can select SVRT option

Your second statement is almost completely the opposite what I was trying to say, so let me get rid of the subtleties and make a much more direct (and very different) statement:

It's usually best to use hardware encoding/ hardware acceleration (whenever SVRT is not available), as it results in a high quality output in the shortest time.

In rare cases, hardware encoding may cause noticeable visual artifacts, and then it's best to produce videos in a normal way (the speed which CPU is using)


So, the short answer is to use SVRT whenever it's available, otherwise use Intel QuickSync.

I would only look at unchecking that box if you ever see something that doesn't look right in the produced video. Odds are you'll never even encounter an issue like that, but I wanted you to know that using the CPU only for producing is a good workaround if that ever happens.

Hi optodata,

Thanks very much for the detailed explanation. I think I understand better this time. Thanks for yr precious time


Have an awesome week ahead
