HEVC compression artifacts

nicolesharp100 wrote on 12/7/2022, 9:59 AM

I am having a problem whereby noticeable compression artifacts (appearing as vertical streaks) are present in certain videos when exporting as HEVC with Magix Video Pro X14. These artifacts disappear when exporting as MP4/AVC instead. I thought that HEVC was not supposed to have any noticeable loss in quality when using the same average bitrate as AVC? Do I need to export all of my videos as MP4/AVC instead of as HEVC/MP4 if I don't want any noticeable compression artifacts in the videos?

https://nikkisandbox.dreamhosters.com/temporary/magix/

The operation that I need to perform is to rotate the video counterclockwise by 90 degrees and then export as MP4.  I go to "Effects" --> "View/Animation" --> "Orientation" --> "Rotate".  I tried exporting as both HEVC/MP4 (preferred) and MP4/AVC.  The original video is 1080p60 MP4 with an average bitrate of 60 MBd (from a DSLR camera).  I set the export for both AVC and HEVC as averaging 64 MBd with a maximum of 128 MBd and CPB as 15 MB.  Maximum GOP Length is 60 and GOP Structure is Auto. Profile Level is set to the highest and Coding Quality is Best. HRD is enabled for MP4/AVC.

When attempting to export as HEVC MP4 after rotation, the video filesize is reduced from 6.97 GB to 43 MB, which seems much too small even for HEVC, so this could be an error in the HEVC encoding from Magix.  Noticeable and unwanted compression artifacts are in the resulting video.

I am using 64-bit Microsoft Windows 10 Education for an AMD Ryzen 3 2200G CPU with 32 GB of DDR4 system RAM plus an AMD Radeon RX 550 GPU with 4 GB of GDDR5 dedicated graphics RAM.

Hi

. . . .  I set the export for both AVC and HEVC as averaging 64 MBd with a maximum of 128 MBd and CPB as 15 MB.  Maximum GOP Length is 60 and GOP Structure is Auto. Profile Level is set to the highest and Coding Quality is Best. HRD is enabled for MP4/AVC. . . . .

Unless there is a compelling reason to change the export settings, I would strongly against doing so, they have already been optimised for the given resolution, framerate and encoding format, at best you may gain a marginal improvement in perceived video quality, at worst you have severe artefacts or an unplayable file.

A MediaInfo analysis so the exported HEVC video file is not - averaging 64 MBd with a maximum of 128 MBd - it is 121 kb/s which accounts for the severe artifacts - the bit rate is 1000 th of what it should be.

It seems to be a bug with the HEVC encoding on Video Pro X14 then. I tried exporting multiple times but it always comes out the same for HEVC. Can anyone duplicate this? Screenshot attached with the HEVC export settings used.

No bug in the HEVC codec, I think, sorry!

I just carried out a very quick test on a file I had on the timeline: export to mp4, default settings, file size 303 MB; export to mp4 with HEVC, default settings, file size 302 MB. No artefacts in either exported file.

The settings you show in your screenshot are not the defaults. This is what I see as the defaults (my file was 29.97 rather 60fps but everything else should be similar)

Yes, the HEVC encoding works correctly for all the other files I have tried so far. I am thinking perhaps there is something in this specific video file maybe that tricks the encoder into using a much lower bitrate than set by the user, perhaps because of the large number of black pixels in the video.

The default HEVC settings have a much lower quality than I would like, with an 11 MBd average bitrate, as compared to the original video which has a 60 MBd average bitrate (as given by the camera specifications). The goal is to rotate and export the video as losslessly as possible with MP4 compression.

Hi

. . . . It seems to be a bug with the HEVC encoding on Video Pro X14 then. . . . .

No - as I said previously it is the settings you have changed.

Assuming you are in a NTSC TV standard region the default HEVC 1920 x 1080p 60 fps, export settings are:

There is no need to use the settings you previously quoted or shown in the image above, your source video file is only 54.6 Mb/s (nominal target is 60 Mb/s) h.264/AVC encoded, HEVC encoding uses/gives a significantly lower bitrate for the same perceived quality as h.264/AVC encoded video of the same resolution.

Also note that the Average and Maximum bitrate values are target values. Depending on the video content these may not be achieved, eg a slow changing, low detail scene will use significantly less data/second compared to a scene with fast action and/or high detail.

I have exported your video clip from VPX 14 using the above default settings and the average bitrate is 5 842 kb/s (5.7 Mb/s) which is in line with the very low detail in the source clip.

So is that the exported MP4 file from VPX 14 and is the image rotated?

Why did you rotate the original file? Did you use the size position rotation to also alter the size of the sun within the frame while in the project and fit it to a landscape orientation?

Out of interest, I ran that copy of the file through VPX 14 again with an additional bit of tweaking and exported to HEVC using the preset for 1920 x 1080 and then OBS recorded the result of the last few minutes.

I can only wonder at what one could do with the original file.

There are a lot of dust spots that need cleaning off of that sensor and I'm not including the seven sun spots.

@johnebaker @johnebaker @emmrecs @CubeAce

Caveat: my info is from MMS 2023.

I never use the defaults for any of my exports and I have never had an issue. There's probably no point in increasing the bitrate above that of the source file, but there should be no problem doing so (or lowering it drastically, for that matter.

@CubeAce 

the MediaInfo file doesn't show it to be 60MB/s and not 60fps

Ray, the file is 60fps (59.94 to be precise).

I loaded the project MVP and exported 10 seconds worth (that took 21 minutes!) and the file looked OK to me: average bitrate is 53mb/sec.

I wonder if it has something to do with the hardware encoder setup or drivers or if it is indeed a bug?

All my forum comments are based on or refer to my System 1.

My struggle is over! I built my (now) system 2 in 2011 when DV was king and MPEG 2 was just coming onto the scene and I needed a more powerful system to cope. Since then we've advanced to MP4 and to bigger and bigger resolutions. I was really suffering, not so much in editing (with proxies) but in encoding, which just took ages. A video, with Neat Video noise reduction applied, would encode at 12% of film speed. My new system 1 does the same job at 160% of film speed. Marvellous. I'm keeping my old system as a capture station for analogue video tapes and DV.

So is that the exported MP4 file from VPX 14 and is the image rotated?

Why did you rotate the original file? Did you use the size position rotation to also alter the size of the sun within the frame while in the project and fit it to a landscape orientation?

Ray.

 

 

No, I only used "Effects" --> "View/Animation" --> "Orientation" --> "Rotate". This means that there are actually more black pixels (since the Sun is smaller) on the rotated video than in the original video (rotating from landscape to portrait but framing within a larger landscape box) so the filesize should be smaller, assuming all else is equal.

Hi Alwyn

. . . . The encoder settings that Nicole has used are the default for her file, at least in MMS 2023 . . . .

I get the same with the Nicole's project loaded in VPX 14 and MMS 2023. The settings you are seeing are the last export, using custom settings, that are saved in the project file.

The default HEVC 1920 x 1080 59.97fps settings are as I posted above.

My struggle is over! I built my (now) system 2 in 2011 when DV was king and MPEG 2 was just coming onto the scene and I needed a more powerful system to cope. Since then we've advanced to MP4 and to bigger and bigger resolutions. I was really suffering, not so much in editing (with proxies) but in encoding, which just took ages. A video, with Neat Video noise reduction applied, would encode at 12% of film speed. My new system 1 does the same job at 160% of film speed. Marvellous.

I didn't think of that. If it is a bug specific to the AMD hardware acceleration: I tried disabling the hardware acceleration, but it is slooowww. Not even practical to test. For now, the best solution seems to be to simply use MP4/AVC exports instead of HEVC, since I don't really want to scrutinize each video to see if the HEVC worked correctly or not. The file sizes are larger and it takes longer to upload to YouTube, but it's no different than using the original videos, which are already recorded in AVC/MP4 without HEVC. If it is a problem specific to AMD, hopefully someone from Magix reads this and can patch it. Otherwise I can try testing it on my laptop with Intel Iris Xe integrated graphics instead of the desktop with AMD Radeon RX 550 dedicated graphics.

Here is a similar video that is only 5 seconds in duration (33 MB):

https://www.youtube.com/playlist?list=PL5fT0c29NhOq0juNSEu1w6I4kzJckJVh-

Note that YouTube compresses the video and actually introduces its own noticeable compression artifacts for the YouTube version not present in the original video.

https://nikkisandbox.dreamhosters.com/temporary/magix/MVI_0781.MP4

https://nikkisandbox.dreamhosters.com/temporary/magix/MVI_0781-HEVC.MP4

This problem is duplicatable even without any edits being made to the video. Simply loading the video into Video Pro X14 and then exporting it as HEVC with the best possible settings (for a 60 MBd video) will reproduce the compression artifacts. So it seems to be a bug if the same problem is for multiple videos (taken from the same camera of the same object). My other HEVC exports from the Canon EOS Rebel SL2 (200D) DSLR camera were of Terrestrial objects so I may have simply missed any HEVC compression artifacts introduced by Video Pro.

Hi Al.

That file has been videoed in portrait orientation. Did you turn it 90º anticlockwise as @nicolesharp100 did for export?

That has turned out to be a bit of a pain to do in VPX 14. I thought I would just be able to use one axis but it twisted as it was rotated.

I am currently exporting an H264 file using a 9:16 ratio at a bit rate almost exactly the same as the original MP4 file at 54.6 Mb/s (6.97GBs) as an all I frame GOP structure and it's estimated to take me another 2 hours Because I've already compensated for exposure etc. I will probably leave that to complete while I go to bed. Then I'll import that again but compensate for a landscape export using a default H265 setting and adjusting the zoom level so the sun size is the same size it would have been for the portrait export. I will export an H264 file (With default settings this time) as well for comparison. I have not downloaded or used the MPV file as there may be differences between Nicole's program and my programs and I'm aware that may not be a good option for me.

How is MS 2023 running for you? I'm struggling with VPX 14 from a performance standpoint. It is not as smooth running as VPX 12 was on my machine or as fast at exporting.

 

Ray.

You do not need to make any edits to the video to reproduce the problem. Simply save the original video as HEVC:

https://nikkisandbox.dreamhosters.com/temporary/magix/MVI_0781.MP4

Try using the 5-second video (33 MB) . It is much easier for testing. This reduces from 33 MB to 633 kB (52X compression) but has the same noticeable compression artifacts as the longer video. It sounds like perhaps it could be a problem with the AMD hardware acceleration if you can export as HEVC without noticeable compression artifacts.

Out of interest, I ran that copy of the file through VPX 14 again with an additional bit of tweaking and exported to HEVC using the preset for 1920 x 1080 and then OBS recorded the result of the last few minutes.

I can only wonder at what one could do with the original file.

There are a lot of dust spots that need cleaning off of that sensor and I'm not including the seven sun spots.

Is there an easy way to remove DSLR sensor dust from videos with Magix Video Pro X14?

Hi

. . . . This reduces from 33 MB to 633 kB (52X compression) but has the same noticeable compression artifacts as the longer video. . . . .

We are going round in circles here, to get that degree of compression I assume you have been changing the bitrate settings and are setting a too low a value, which will give significant artifacts in the exported video.

Here is the MediaInfo data for the MVI_0781-HEVC.mp4 file

Bit rate                                 : 943 kb/s

The video has been crushed to death - the bitrate is too low - the default setting for this resolution and framerate is Average 11000 and Maximum 13000 kb/s - note the units are kilobits/sec which equates to about 11 and 13 Mb/s and compare this to the actual bitrate of the exported video which is 943 kb/s ie 0.9 Mb/s.

Uploading this to YT is only going to make it worse as YT will re-encode the video to lower resolution version which will exhibit significantly more artifacts after recompression.

Have you tried exporting the video using the HEVC 1920 x 1080 5997 fps preset - see image below - without making any alterations to the bitrates or any other parameters in the export settings?

If not please do so, the exports I have made with your project and video file are fine with the default settings and do not suffer from the artifacts you are seeing.

At HEVC is Full HD with up to 30 FPS = Level 4.0

Full HD with up to 60 FPS is level 4.1

Magix Video Software doesn't do well when the profiles and levels are wrong.

Hi Nicole.

Is there an easy way to remove DSLR sensor dust from videos with Magix Video Pro X14?

Not that I'm aware of but NeatVideo may be able to. (a third party plugin). John EB or one of the others here that use it may be able to say for sure.

Some cameras have the function to remove dust spots in camera but personally I prefer to clean the sensor as the longer dust remains on the sensor the harder it eventually gets to clean it off. You need to get the proper and correct sized swabs and cleaner and quite a bit of practice before you can actually clean a sensor with maybe using just one or two swabs but it gets easier over time. The reason a lot of pros use more than one camera body is to stop from changing lenses outside.

As John has also pointed out YouTube will re-compress any file uploaded to its servers. HEVC probably definitely more so than a high bit rate MP4 file. This is not as bad as it once was as now all video uploads seem to be encoded with the newer Vp09 method now as long as it is seen at 1080p or higher. At lower resolutions they still use av01 although I suspect eventually all files will be Vp09. This is being done to lower storage space as it is costing YouTube a lot to store everybody's videos.

I will be doing my final re-encode of your file tomorrow to see how it goes. Good tracking by the way.

Ray.
