Exported video delayed, audio slipped, no GPU acceleration

Hi and Welcome.

Did you check the required machine specs before purchase?

Also why is one video playing at 25 fps and the other at 30fps?

Ray.

Yes, I'm sure I have the required system specifications:

CPU: AMD Ryzen 7 2700X Octa-Core 4.0 GHz (8 core 16 threads)

RAM: Corsair Vengeance RGB Pro (2x8 GB, 3200MHz, Dual Channel)

GPU: AMD Radeon RX 5700 (8GB VRAM, 1725MHz, Supports DirectX 12)

OS: Windows 10 Pro (Latest 2004 build)

I have rendered both with 59.94 fps. I adjusted it to the recorded video's framerate.

Hi

@Scenestealer @Levente-IlyKovcs

Those specifications are a little misleading as they are for VPX12 and @Levente-IlyKovcs has VPX11, so the comments about Hardware acceleration with AVC content with AMD cards do not apply. VPX11 can only utilise HWA on Nvidia cards with HEVC material during preview and during HEVC export. Beyond this, HWA export can only be carried out with with an Intel CPU that has an integrated Intel iGPU as mentioned in the fine print at the bottom of the specification list.

@Levente-IlyKovcs Can you export the material correctly without Hardware Acceleration turned on?

@Scenestealer

I just tested it now: I unticked the "Hardware acceleration" option in the advanced settings, but the exported video is still delayed, playback speed is slow, audio is slipped. Just like the YouTube video, that I attached.

Thanks for the hint anyways.

Apologies Peter.

The correct system specs for that version of VPX.

Although I still don't understand the frame rate discrepancies between the two YouTube example videos or the previous comment, "I have rendered both with 59.94 fps. I adjusted it to the recorded video's frame-rate". I thought screen recording software recorded at full frames per second.

Were both exports setup manually or were they automated?

Yes the slow rendering times are down to the program not being able to use all the hardware and relying on the CPU, but does not account for the differences in the output of the video files from both programs.

There has to be setting variations somewhere.

Ray.

I did not changed/adjusted anything. I only use the default settings. Both software recognised the recorded video's framerate and I clicked the button to adjust it. I think that for a $400 software, it would be great to have AMD GPU supported hardware acceleration as well. But that is not the main issue. I can live with CPU rendering only, but as you can see the exported content is unwatchable.

I will try to reinstall the program, and I hope it will solve it, but I'm not sure. Only Quicktime export can produce a watchable video, but the rendering is slower than MPEG-4.

Hi

Can you analyse one of the source videos, that is showing the lag on export, with MediaInfo and post the results from the Text view.

Dear @johnebaker,

I don't have the original video, but I recorded a new one and rendered it with both software. The issue is the same.

However I realized that the lag and delay is only happening, when I render it above 1080p. But I would like to produce 2K quality videos, so this is not an option. I uploaded the 2k videos. The first is the original raw video file, the second is rendered with MAGIX Video Pro X (the delayed) and the third is rendered with Movie Studio 16.0 Platinum

Hi.

Thank you for the MediaInfo on the original.

Now if you could supply the MediaInfo for the other two exported files we will be able to possibly see what is going wrong.

Ray.

For some reason it rendered the video in 25 FPS, but I set 60 fps when rendering. :(

@Levente-IlyKovcs @CubeAce @johnebaker

Hi.

The first things I notice is that the exported file from VPX has changed the GOP structure and over halved the frame rate. It is also half the file file size due to the lower bit rate used when encoding. I think you have imported the original video with the wrong settings for the clip. You may have to adjust that manually and possibly the export settings as well. You can't use the last project settings on a new project if the video you are going to import is of a different resolution and frame rate.

But await the other members input before you take what I say as gospel as they are more experienced than I am.

Hi

The most likely cause of the problem is that the source video has been recorded at a variable frame rate which VPX / MEP can not tolerate (along with other non linear editing systems). If your recording settings can not be adjusted to give a constant frame rate file then the only option is to first convert it to constant in one of the video converting programs available.

Hi Peter. I think it's worse than that.

I downloaded the supplied file and placed it into my copy of MEP (I know it's not VPX).

But before that I looked at the MediaInfo from the downloaded file.

First problem. There is no project preset within MEP that matches the frame size and that frame rate (I was looking to do 60fps) So I made a custom preset. The file seemed to load and display OK.

The same problem happened when exporting and had to do a custom export setting. The export only showed a portion of the frame although it played OK within the MEP editor window. I closed the project and re-opened it. MEP kept thinking it was a 360 video. This could explain the export only showing a portion of the frame. Sound seemed in sync with the video from what I could see. I did get hardware encoding and the export took a minute and a half to render.

I don't know if is just because of the variable frame rate but MEP did not like this file.

What is the screen capture device?

Ray.

@johnebaker @Scenestealer @Levente-IlyKovcs

OK I tried again with the same settings but exported as HEVC. Loading the project again made MEP show a 360 view in the editor that I had to change to 2D. I still got hardware encoding on export but the export took over four minutes.

Here is the MediaInfo in the converted file.

I've uploaded the resulting video to YouTube for you to play and see the result.

In this instance the variable frame rate of the source file did not make any difference to the audio sync or as far as I can tell the visual quality of the file output.

To view the file at 2.7K you will have to follow the YouTube link in the video and select the resolution there.

The video is set to private viewing so can only be seen through the link above.

[Edit] The video now also has a copyright claim against it so can not be viewed in some countries.

As such I will take down the video at the end of next week.

I will take some screen shots to show my import and export settings.

Side by side comparison between my conversion showing on You Tube and the original file.

I set up the project and exported using the following procedure.

First I matched as closely as I could the movie clip's settings for importing the file into the project based in the information from ViewInfo.

The first export to MP4 I could not get to work, so I shut down the program. When I thought about trying to export the file as HEVC I re-opened the project.

You can see I renamed it. The Bak file was created I think when the first export didn't work correctly. Either way I opened it and then got this. I'm assuming as there is no preset for import within MEP that MEP is getting a confused set of instructions when re-opening the project. There appear to be few settings for 2.7K video. Either import or export. That could be a mistake by Magix not to include any as I know that export format is becoming more popular at all frame rates.

It didn't matter which option I chose, but I then always got this view (below) in the Editing screen which was also the result I got when I did my MP4 export.

So I changed the view in the editing screen.

That rectified the screen view and playback.

Now for the export to HEVC.

Again there is no preset that matches the file's profile so I typed my own settings in.

And in the Advanced section I set the following.

The resulting video I sent to YouTube where it can be viewed in my previous reply.

[Edit] That video is now available to watch at 2.7K but I will take it down on the 22/08/20.

@Levente-IlyKovcs I don't know if you realise or not that the file you uploaded to YouTube from using Movie Studio 16.0 Platinum is only available at 1080p.

So in conclusion, my findings in this instance are that I can export a virtually indistinguishable copy of the file for upload but at no time can I rely on any available preset for setting up such a project or exporting the final version of the file and that custom made presets must be made for both the project and rendering and saved as custom settings if I wanted to do more work and export from this type of file.

Even then some settings within the project may have to be altered each time the project is opened as MEP (and presumably VPX) seems confused as to how to display the files in the preview editor window which switches to a 360 file view on opening.

@CubeAce @Scenestealer @johnebaker

Woah, thank you very much for the effort and help!

Yes, I rendered the Movie Studio export in 1080p by a mistake, but Movie Studio works perfectly in 2K as well.

I recorded the game with Radeon Software's built in Video Recorder. It uses GPU as a capture device. There is not much to change in it's settings. It's the same equivalent of NVIDIA's Shadow Play Recorder.

I tried to recreate your steps, however some options were missing on my side. While rendering I got an error unfortunately.

Finally I reinstalled the software and payed attention not to choose any video settings preset in the movie settings window. (Just like you did on your first attached image.) This way, I could recreate your settings and it finally works! I also switched to OBS as a video recorder, and this seems to work perfectly.

I just want to mention, that AMD GPU acceleration support would be very helpful from the MAGIX developers. It could reduce the render time A LOT for a bunch of people. After all, AMD is famous for effective rendering with their GPUs. Hopefully it is a plan in the future updates of Video Pro X11, but I'm not that optimistic. Only, if there would be a way to suggest it to the developers..

Anyways, thank you very much for the suggestions!

Glad it's sorted Levente.

You should find the output from OBS studio to be much more MAGIX friendly and possibly give you an even cleaner looking video although the problem of the apparent lack of import or export settings for 2.7K video files at various frame rates would make me make a few custom presets to work with. In fact I will do that as one my cameras can capture 2.7K footage at all normally used frame rates, so there was a bit of self interest in finding a solution to the problem. The variable frame rate in this instance did not cause any trouble which when we see some footage from phones often does, hence Peter's earlier comment. It could easily have been a contributory factor but in this instance I don't personally think it was. It was also very helpful of you to make available some problematic footage without which I could not do any testing.

[Edit]

Earlier I posted incorrectly the specs for the new version of VPX which apparently is starting to support some AMD architecture more. I personally don't know how hard that is to incorporate into any software but Adobe has managed it so one can only hope. It would expand the amount of Magix based customers I'm sure.

Hi

As @Scenestealer has commented:

. . . . the source video has been recorded at a variable frame rate which VPX / MEP can not tolerate (along with other non linear editing systems). . . .

Is the issue - I have tried both the original variable frame rate (VFR) and a conversion (MovAVI) to Constant frame rate (CFR) exporting as HEVC using VPX.

The VFR export has the audio way ahead of the subtitles and action, the CFR is in sync.

@Levente-IlyKovcs @johnebaker @Scenestealer

. . . . There is no project preset within MEP that matches the frame size and that frame rate (I was looking to do 60fps) . . . .

When importing video did you not get this dialog?

Clicking Adjust automatically sets the projects settings correctly, the export dialog also is also then correct.

Also converting in MEP or VPX will not work - they not like VFR source video - you need a converter such as MovAVI or Handbrake to do the conversion correctly.

@johnebaker I actually got that dialog. No matter what I clicked, adjust or do not adjust, it did not help, but thanks for the info!

CubeAce wrote on 8/15/2020, 5:31 AM

Hi John.

No. I did not get that dialogue box. I recorded each step as I took it above.

The final export files' audio matches exactly with with the original file I used.

I could put both files onto the timeline to show you. I did not convert the file before use.

I have put markers next to and on some of the peaks in the audio tracks. Both tracks are of identical length.

As I said earlier, that some past phone footage in the past with variable frame rates has cause audio sync problems but could that not be down to the converter used within the phones and not in this instance?

You should try the file for yourself. It only took a short while to set up and use.

[Edit] If you are saying the original files audio is out of sync with the dialogue, there is no way to tell how the game plays it out, but the sound effects seem in sync with the action to me.

It does not help with the audio issue, all it does is set the project settings to match the imported video.

Hi Ray

. . . . I did not get that dialogue box . . . .

Try starting with a project setting eg 1920 x 1080 25fps then add the original.mp4 clip - if the dialog does not appear that suggests you clicked the Do not show again option on an occasion when it did appear - you can Reactivate dialogs in the Program settings, System tab

. . . . If you are saying the original files audio is out of sync with the dialogue . . . .

That is not what I am saying - it is on export MEP/VPX to a constant frame rate, that is throwing out the audio synchronisation.

Give MEP/VPX an original.mp4 converted to CFR and the audio in the export is in sync.

@johnebaker

Hi John.

In that case, I probably didn't get that dialogue as I set the project up as closely as I could before importing the file. I have not deactivated any warning dialogues. As you can see from my last image above, both files are the same length. When starting new projects I have always set a project up to accept and match the footage I'm importing. It is only after, if I have used a file of a different resolution of frame rate that I get warning messages.

I did get a warning but not that one, as shown earlier.

I also do not use the 'Use settings as presets for future projects' settings as I often record projects in-camera at various frame rates and resolutions, dependant on the possible event content.

Have you tried to do this conversion without altering the original file for yourself yet?

Ray.

If the dialogue said what the one in John's screenshot showed then neither choice would, because the project movie settings and imported file settings are the same! Not really sure why the message would appear at all.

@johnebaker

Any idea John? Maybe it detected a frame rate discrepancy which equated overall to less than 2 decimal places, owing to the slight VFR.

Try starting with a project setting eg 1920 x 1080 25fps then add the original.mp4 clip

This is what I usually suggest in the case of unusual formats - deliberately start with incorrect movie settings then drag the clip in, and let VPX / MEP do the hard work figuring it out and filling in the boxes! This should then enter these settings in the export template also.
