@nicolesharp100 Hi, I see something, I've just got up after 3hrs sleep so I'm a bit blurry at the moment tho 🥱😁,

It's noticeable on the feather so I looped it

@nicolesharp100 @johnebaker I downloaded the project, this is the Project settings it chose, which Export settings you chose would be good to know?

Bitrates quite low, so I changed it to this & set it to 60, I'll get back to you after Exporting both

@nicolesharp100

Hi

I am seeing some blockiness in the encoded video and still image.

Which export preset are you using and did you change any of the settings such as the Bitrate or any of the advanced settings?

Download and install MediaInfo and analyse the exported video clip and post the results, see this tutorial if you are not familiar with MediaInfo on how to setup MediaInfo and analyse a video clip to get the correct data we require.

I used 1080p60 MP4 with everything default settings except GOP Structure set to Auto (I don't know what this is), Profile set to High, Level set to 5.2 (I don't know what this is), Coding Quality set to Best, HRD enabled, and audio bitrate set to 192 kbit/s (but there is no audio).

"Multiple GPU" is the default option, but there is only one GPU: AMD Radeon RX 550 (for the AMD Ryzen 3 2200G CPU). Operating system is 64-bit Microsoft Windows 10 Education with 32 GB DDR4 system RAM plus 4 GB GDDR5 dedicated graphics RAM.

I am on the free trial for Movie Studio 2023, but the free trial for Video Pro X14 has already expired. I saw there are a number of performance improvements for Video Pro. I was leaning toward Movie Studio instead of Video Pro since it is cheaper, but is it possible that the rendered videos for AMD Radeon RX 550 might actually be different on Movie Studio versus Video Pro? Let me know if you can duplicate the problem to see if it is just my system or the software settings.

@nicolesharp100 Exporting now the settings in your pic above, 6000-8000 is a bit low, I already exported the higher one in my pics 28000-35000, I'll get back to you in a minute or two, I have MS2023 I'll try that also but as far as i know the export settings etc are the same,

That makes sense. I didn't change the default bitrate. Is this an arbitrary setting or what is the maximum or maximum recommended value for the highest possible video quality?

For static images, wouldn't a constant bitrate be better? I don't see an option to change from a variable bitrate to a constant one?

Should I be using "GPU" or "multiple GPU" if I have only one GPU? "Multiple GPU" is the default.

I think it is just the bitrate. I was using the default export settings. I tried exporting multiple times, each time doubling the bitrate. The feather is a good test and starts to look a lot better at about 16384 kBd average / 32768 kBd maximum / 2048 kB CPB. The artifacts become unnoticeable at 32768 kBd average / 65536 kBd maximum / 4096 kB CPB, so that is probably the recommended minimum setting then for a video slideshow.

Should I be changing the CPB in addition to the bitrate?

What does the GOP Length do? Another forum thread says to leave that at default.

@nicolesharp100 Hi, It's hard to see the difference in the two export choices but if you concentrate on one part of the feather (near the grass shadow) as the no's swap at the bottom you can see the 'artifact' or whatever it is, It's not as noticeable as your vid tho.

I'll try it all again in MS & see if there's any difference,

Can you show a pic of your settings, File - Settings - Program - Device options or click Y on the screen to open them,

@nicolesharp100 I would use the presets in the dropdown menu, UHD or FullHD like in the pic below, you can if you want choose a UltraHD option, that would auto give you a higher bitrate, then you can reduce the Resolution to 1920 x 1080 & still keep that high bitrate, but that might be pointless, there's a threshold where you don't get better quality just by increasing the bitrate beyond a certain point, beyond it's optimum, it would just make the file size bigger & slow down export,

The screen size will also determine how visible the artifacts are. I am using a 24-inch 1080p60 desktop monitor to view the 1080p60 video.

The photos were taken with my Canon EOS Rebel SL2 (200D) DSLR camera, which has an average bitrate for 1080p60 high-quality video of 57467 kbit/s. So I should probably set that as the default then if I want the exported MP4 videos from Movie Studio to be at the same quality as the videos recorded natively by my DSLR camera.

@nicolesharp100 Yeah I'm using a 32" 4K screen but I would still export in UHD 3840x2160 59.94 from the dropdown list & change it to 60fps even though you're using a smaller screen, your media player downscaling of the video to play on your screen is better than it being upscaled.

@nicolesharp100 yep, matching the project to the media is always the better option, not always easy with big photos like yours,  I've got to go to work, I'm sure the others on this forum will have a say.. hope you work it out,

PS, can you show this window from settings

Hi

. . . . I used 1080p60 MP4 with everything default settings except GOP Structure set to Auto (I don't know what this is), Profile set to High, Level set to 5.2 (I don't know what this is), Coding Quality set to Best, HRD enabled, and audio bitrate set to 192 kbit/s (but there is no audio). . . . .

Gids comment  6000-8000 is 'a bit low' is an under statement given the source videos contain a lot of fine detail in the grass and trees which is where the majority of the blockiness is very apparent.

The standard 1080p 60fps preset, as indicated in Gids image of the presets above, has a target average bitrate of 28000 and maximum of 35000 - this should be capable of producing good quality video without any other modifications, which we advise against doing, as the presets are optimised already.

I would also recommend thet you add about 20 - 30% sharpeness in the Effects, Movie Effects settings (Master effects), Sharpness option

I use 30% for the video and images I use - 4K UHD 3840 x 2160, setting anything higher can result in a halo effect which is detrimental to the image. No sharpening is applied to the individual images/video.

HTH

@nicolesharp100 MS2023 exported as UHD, i only changed the setting to 60fps & chose Best in the Advanced window. much better images, I don't think it will show on here so i'll put it on YT
