Yeah! Magix video edit 2014.

@SSB Sorry no idea at the mo, it's only a small aspect but that shouldn't darken the image, don't think so anyway,

Stats for nerds on the dark YT version shows the image 854x480

But the 'Original video' shows this,

I downloaded the 5GB version from that link,

Apart from differing frame rates & AR's I see no reason why it's dark on

 

I might be asking unknowingly, But can you suggest what to do?

@SSB

Hi

Looking at the mediaInfo data the original is in the BT.601 colour space, with a TRC (transfer coefficient) of BT.470.

Youtube has ignored the BT.470 TRC and set the video to the BT.709 colour space

This change will shift colours eg the orange background in the intro becomes more red, and makes the video darker in the greens and blues as can seen below - the screen shots are the same frame in both the YT version (right) and original (left).

For more information on this behaviour see the Colour spaces section of YT's upload requirements.

Assuming you imported the original into Movie Studio and exported it for upload to YT - is the export darker and what colour space is it using - download and install MediaInfo and the exported clip and post the results, see this tutorial on how to setup MediaInfo and analyse a video clip for all the data required.

To get around this darkening load the original into Movie Studio and export a section of the clip where the darkening is occurring to h.264 MP4 and test upload to YT. Repeat the testing adding Gamma correction to the video clip.

I will have to take a look at that.

I will tell you how i captured and edited the game. I used a ps2 with a scart to hdmi converter to capture card. With obs studio. So i used 1920x1080 for capturing. But used in video studio 640x480, for some reason, when exporting. I also wonder if i should use another format then mpeg4.

Do you think I can export the videos rather like 1920x1080 to fix the issue?

@SSB

Hi

I have gone through the MediaInfo data of the file you uploaded again and compared it to an export I made from Magix Movie Studio at the same resolution - there are some differences in the MediaInfo data of your original file you provided and my export - for which we require some additional clarification and information:

• you mention video studio above and Video edit 2014 in your previous post.
  
  What is the full name and version number of the program as found under Help, About?
   
• If Movie Edit Pro 2014, do you have installed, and use, the MainConcept codec for export?
   
• . . . . With obs studio . . . .
  
  Can you provide a MediaInfo data analysis of the file from OBS. MediaInfo can be downloaded and installed from here, if you are not familiar with MediaInfo, see this tutorial on how to setup the program up and analyse a video clip for all the data required.

I believe the problems are with the OBS Studio recording settings.

If the MediaInfo data Gid got from the uploaded video file is from the OBS recording then here is your MediaInfo data compared to the results I get from using OBS Studio.

My files work OK both within editing and then rendering and uploading to YouTube.

You can try altering your OBS settings to my settings to see if you get any improvement.

Hi

Thinking further on this issue and the workflow involved, I can see no reason why the video is not captured using MEP 2016.

The capture card should be recognised by MEP 2016 using the Analog recording option, thus eliminating the colour space issue, with export from MEP 2016 to MP4 file with h.264 video encoding and AAC audio encoding at constant framerate for uploading to YT.

John EB

@johnebaker @CubeAce I did notice the different colour codes, BT 601 & BT 709, I know nothing about those tho so didn't mention it, brain's still a bit fuzzy too go online n learn 🤯🙃😂,  I'd be interested tho as to why the clip is BT 601, is this a 'normal' colour for export from Video studio, Video edit 2014 or whatever software @SSB used,

How the video was captured is surely not so important, how it was exported after editing from Magix is tho?

@johnebaker @Former user @emmrecs @SSB

Hi John.

The only things I have against using Movie Studio or Movie Edit Pro etc are the recording settings are a little limited and if you are using multiple monitors I have found no way to select which monitor screen to capture. The resulting files can also only be used within the Magix editors unless you change the resulting file extension to .avi or .mp4.

Hi Gid.

Nice to see you back on the forums.

I am not sure whether the file that was uploaded by SSB was the OBS recording or the video file after exporting from what I'm assuming is Movie Edit Pro 2014.

OBS Studio does not have a BT.470 colour space option but if the video is recorded without enough bandwidth in the recording to give a wide enough gamut to the colour density then it may be possible the colour palette becomes limited in range. Of that I'm not overly sure but would seem one of a couple of likely outcomes.

If the colour space was read as BT.601 but the recording did not have the tonal range to render it correctly then one of the side effects is that colour tones get shifted to the next nearest available colour on that colour pallet which means an orange could turn and be rendered to a darker looking brown for instance.

For various reasons this is why I choose to not use variable bit rates and keep to using a full BT.709 colour space when using OBS Studio.

Ray.

I’m going to try export a video with same resolution as I had in obs studio. And see if it works on YouTube

@SSB Sorry meant to mention, you asked earlier 'Do you think I can export the videos rather like 1920x1080 to fix the issue', Changing the aspect ratio to 1920x1080 wouldn't fix the issue but you're always better working/exporting your video at the same aspect as it was captured,

What editing software are you using?

@Former user

Hi

. . . . How the video was captured is surely not so important, how it was exported after editing from Magix is tho? . . . .

If Magix video edit 2014 (Movie Edit Pro 2014 ?) can detect the capture card and use it, then there is no technical reason for not using it to capture thus eliminating the Colour space and VFR issues.

There are some aspects of this issue which are puzzling:

• The video provided is not the export from OBS, there are missing and incorrect parameters in the MediaInfo data and @SSB has commented the video was captured at 1920 x 1080 in OBS, but exported using video studio at 640x480 resolution
   
• If the video is an export from Magix video edit 2014 (Movie Edit Pro 2014 ?), some of the parameter values are not possible user the Magix encoders ie:

From the MediaInfo data:

• Frame rate mode : Variable
  
  MEP cannot export MP4 AVC VFR video, only Constant framerate in accordance with the Video standards
   
• Color primaries                          : BT.601 PAL
  Transfer characteristics                 : BT.470 System B/G
  Matrix coefficients                      : BT.470 System B/G
  
  MEP only exports BT.709 (for AVC/h.264) for all 3 options.

The only other possibilty is that the export was encoded using the MainConcept encoder from MEP.

@johnebaker @Former user @emmrecs @SSB

Hi John.

That was inspired and can confirm that is probably the cause. It has definitely caused a colour profile change to a darker overall video.

I just tried exporting via the main concept encoder and found the probable MainConcept settings to produce a file with those export values. The mediainfo along with the MainConcept settings I used.

Original file still.

Exported video file still. Notice the colour changes in the audience clothing and general darkening.

[Edit] There is probably a wider bit range setting than I used to get this result before avoiding trouble colour wise but going lower with the bit rates only produced files with an undetermined limited colour profile.

@CubeAce

Hi Ray

. . . . I have against using Movie Studio or Movie Edit Pro etc are the recording settings are a little limited and if you are using multiple monitors I have found no way to select which monitor screen to capture. . . . .

This would be true if this were a screen recording, however that is not what I am suggesting.

I am suggesting using the Analog recording option in the first Recording dialog:

Referring to the image below, the capture card should appear at 1 and 2 for video and audio sources, and at 3 the recording format can be set - in this case the camera on my laptop limits the options to 1280 x 720 for MPEG-2 maximum.

Using MXV as the recording format up to 4K 3840 x 2160 and 4096 x 2160 are possible when the capture device supports it.

Hi Ray

Forgot to add to above - the MC export settings look like they are the ones, with the option Allow source to adjust frame rate checking then you should get VFR if the source is VFR.

Definitely a difference between the 2 still frames.

John

@CubeAce @johnebaker Well done for recreating a file with BT.601. but I've lost track a little, the OP file that was shared in the Google link had BT.601 but wasn't darkened, I read it that it had darkened after uploading to YT.

& think you've broke my brain with the mention of 'MainConcept encoder from MEP' & that pic of Magix AVC, the only way i can get Mainconcept is by using Vegas?

@Former user

Hi

. . . . think you've broke my brain with the mention of 'MainConcept encoder from MEP . . . .

Brain fix is available below 😂

The MainConcept codec was an 'add on' option for MEP at one time.

MEP 2016 

John EB

@johnebaker Thanks, I didn't get that at the time 👍🤷‍♂️😉😊

@johnebaker

Hi John.

I don't have any VFR to check that with so I didn't bother checking that box although I suppose on reflection they could have still been created.

@Former user

Hi Gid.

I was more interested in getting both BT.601 and BT470 to show. I had never previously seen (or possibly noticed) BT.470.

For around four years now I have noticed bits of the programs being eroded and taken away with the lowest tiered product getting the most taken away from it. So there is now more differentiation between Rescue You Video Tapes, Magix Movie Studio, Video Pro X, Vegas Edit, Vegas Pro, and Vegas Post. I would think that makes the selection of video editor easier depending on the requirements of the individual when looking at the various offerings.

You are correct. Only the Vegas products now have access to the MainConcept pack.

Ray.
