Hi thank you for your answer.

I began a new project, and the program run into "not responding" state, by accident.

Sometimes it stop saving the project, and makes project file corrupted.

In that case I have to open the copy, what I save regularly for security.

But when I try to edit the scene put in project folder in the source window, the application crashes as a rule.

The task manager shows high power usage on the Magix application, the resource monitor shows overloaded CPU0, and "C" NVMe drive.

The import, export and processing set to NVIDIA Getforce 1660 super, the second monitor supplied by UHD750.

I use the latest drivers.

Hi Gabriel.

The problem may not be the program but how you are using it.

The program can only do what you tell it to do in as much as you first need to tell it what the file resolutions, frame rates, and audio sampling rates you are using or load the first file you wish to use into the program for it to automatically set the parameters for editing. Ideally every other file loaded should have the same frame rates, resolutions, and audio sampling frequencies or problems will occur if using disparate files. The program will not know there are differences and try to treat each video clip the same.

So a sound track from one file may not play at the correct speed or lose synchronisation with the video portion or not play, A difference in frame rates or mixing progressive with interlaced files can produce jerky or smudged / blurred / soft looking images. Worse case scenario would be a crash or lockup.

Changes in resolution will produce poor soft and blocky looking output where such files are inserted.

Most video editing programs will suffer these problems. Some of the very high end programs may be able to cope better with less crashes but the finished results without additional editing with enhancement plugins will look roughly the same.

Most video editors are meant to cope with editing say a set of video clips from the same camera using roughly the same settings. They are not capable of dealing with media from multiple sources.

All of this of course may not be the case for you and just need help setting the program up better but be aware there are limitations to such programs which is why we ask so many questions of users when they post here for help.

Hi Ray,

Thank you, it will be the cause in my case.

My project contains footage from Gopro Hero black 7, 4:3 resolution, an from Huawei p30 pro 16:9 resolution.

The frame rate isn't identical either (25 vs 30).

I mainly use these cameras, I wonder, whether I can edit it if the settings are same, but the file formats differ?

Hi Gabriel.

You will have to check with the Go-Pro Hero Black 7 and if it has the ability to record to MP4 H264, that would be your best bet rather then the HEVC H265 which can be problematic from some Go-Pro cameras if you can't set a constant frame rate rather than the default variable frame rate, especially with the newer Go-Pro models. It would be best to set the same aspect ratios to both if possible. The frame rate jump between the two cameras is a bit high for the program to cope with but you should try setting the project to the higher frame rate rather than the lower one in my experience as it seems it is easier for the program to add additional frames than to work out which ones to take away.

Ideally they should be the same frame rates from both.

File formats, mov.(basic) MP4, mpeg-2, avc etc should not make much of a difference if they are relatively 'common' file formats as long as the other parameters align, including the audio sampling rate. All that would happen is the program may slow down from time to time if it needs more grunt to deal with the amount and type of compression the various files use.

Ray.

@CubeAce

Thank you, I'll check, and will set the cameras by your advice.

@profilaxagm

Hi Gabriel.

I hope it works for you as It works for me using my DSLR which produces mov. files between 25 to 60 fps from HD to 4K, my action camera, which produces MP4 or mov. files from 24 to 60fps HD or 4K, and my phone which while it uses MP4 it has a single 30fps frame rate and fixed 1080 x 1920 HD ratio. I can't say I use my phone that much other than to use it as a larger monitor for either of the other two cameras.

Hi Ray,

In my Gopr 7 black, in h.264 format the available framerates are 25-50, while in Huawei pro 30 there are 30-60.

Do I have to convert one of them with some converting application, before editing with VPX13?

Gabriel

@profilaxagm

Hi Gabriel

Ideally the two devices recording settings should be the same framerate and type ie Constant Frame Rate (CFR), however of the 2 settings the CFR is the most important.

It is possible to use video of different framerates, however there may be problems with movement and pan shots which appear slightly jerky after export due to a change in framerate from the original,.

Hi Gabriel.

The manual for the Go-Pro Hero 7 black can be found on their site here.

Using H264 MP4 does not seem to limit the available frame rates. All frame rates at all resolutions are available but not in all auto modes or some image stabilisation modes. You should be able to find settings that will match the Huawei phone's available settings not using its auto settings.

From the Go-Pro manual.

There are more pages on what is and what is not possible if you follow the pdf link above.

I know John had a Go-Pro at one time. Maybe he can confirm my findings or debunk them if I have read the specs wrong.

Ray.

@CubeAce

Hi Ray,

What I found for GOPRO Hero 7 black, is that 30-60-120 fps are available only in NTSC mode, in Huawei pro 30 I didn't find any possibility to set the NTSC vs. PAL, but I suppose the EU version's phone set to PAL by default.

Is there any issue, if the part of footages uses different video format?

Gabriel

@CubeAce

Hi

. . . . I know John had a Go-Pro at one time. . . .

Not me - personally I have avoided and I am trying to avoid getting one as a replacement for my Sony sportscam that has had one hard knock too many in January following nearly 8 years of good service in the air, on land and underwater.

John EB

@profilaxagm

Hi Gabriel.

I don't think that the colour profile will alter much between the NTSC and PAL versions between the Huawei and Go Pro unless you can see a difference between PAL and NTSC when shooting with the go-Pro.

Do some test shots to see if there are any colour differences. Most action and DSLR cameras don't differentiate between the two as regards to colour spacing in my experience and may only be a reference to the frame rates needed to be supported if transferring to DVD later. There is no PAL 30fps standard. Pal is either 25fps or 50fps. as it refers to the refresh rates of the two interleaved parts of each frame if using an analog camera. the 25 fps being the total amount of 'frames' made up from the two sets of 25 frames that 'interleave' to produce the 25 frame per second rate.

Certainly my 'action cam' does 24; 25, 30, 45; 50; and 60 fps as well as 120 fps and no mention of either PAL or NTSC. The DSLR has PAL and NTSC mentioned but bracketed.() as if information rather than specification.

@johnebaker

Sorry John.

I remember now the conversation of the Sony dying and the fact you were looking for a replacement but not Go-Pro when I mentioned the DJI alternatives.

Ray.

@CubeAce

Thanks Ray, I'll try it soon.

@profilaxagm, @CubeAce

Hi

. . . . There is no PAL 30fps standard. Pal is either 25fps or 50fps it refers to the refresh rates of the two interleaved parts of each frame if using an analog camera . . . .

This is not limited to analog recorders only, there are digital camcorders, eg my Sony HDR-X520V, that record Interlaced AVCHD.

PAL is either 25 or 50 frames per second, a frame being one complete image whether progressive or interlaced video. NTSC is a little more complicated as it has either 29.97, 30, 59.94 or 60 fps - the 30 and 60 fps are technically none 'standard' as far as analog broadcast is/was concerned.

To further add confusion, interlaced video has also been referred to as 50i or 100i for PAL or 60i or 120i for NTSC where the i means fields per second - one frame is composed of 2 fields referred to as top/bottom or odd/even, each of which contains half the complete frame - 50i = 25 fps and so on.

Progressive video is simpler in that there are complete frames only.

In the above I have deliberatey ignored compression applied to digital video.

John EB

@johnebaker

Hi John,

So if in my Huawei there is only 30-60 fps it works in NTSC, ie the only requirement to set my both cameras to NTSC, H.264,16:9, fixed frame rate, no interlaced (mainly for mobil devices).

I'll try it. If the program is still crashing when I try to edit the scene from "program folder" in "source monitor" before putting it into timeline I'll notify the community.

Thanks for the clarification.

Gabriel

Hi Gabriel.

Neither of your cameras shoot interlaced video.

I gave you a link to the user manual of your camera I my replies above and two screen shots earlier and an explanation can be found on page 96 of that manual. You only have to be concerned with frame rates if you are using equipment for playback that relies on using interlaced frames. Progressive video is free from such constraints and and you can use the highest common frame rate between two devices for easiest editing experience. Once video frame rates are matched and edited you can export to any file format you wish, either keeping to progressive exports or interlaced if you need to. I have never had to export a file as interlaced for normal use.

Ray.

@profilaxagm

Hi

I agree with Rays comment

'Progressive video is free from such constraints and and you can use the highest common frame rate between two devices for easiest editing experience.'

This is the best option - using the higher common framerate ie 59.97/60 fps will reduce the problems progressive video has with certain panning speeds, or fast action in the scene being recorded.

I would add to Rays comment ' I have never had to export a file as interlaced for normal use', that if you are going create standard DVD and/or Blu-Ray discs then you will have to use a PAL or NTSC TV standard - which depends on your local TV standard. The program may already be set to the correct one in the Program settings:

@johnebaker

Hi John.

Remember Gabriel's highest common frame rate between the two cameras is 30fps. My old Huawei phone did record at exactly 30 fps.

Ray.

@CubeAce

Hi Ray

AFAICS both the GoPro 7 and the Huawei Pro 30 have 1920 x 1080p 60 fps AVC options.

John EB

@johnebaker

Hi John.

Sorry, I wrongly assumed that Gabriel would shoot at 4K for the additional resolution over frame rate.

Ray.

@CubeAce​​​​​​, @johnebaker

Hi,

Does it make any difference, if one of my cameras set to 60 fps, but other to 59,94 fps (Gopro vs Canon G7x)?

Gabriel

@profilaxagm

Hi.

I'm not sure whether the Canon shoots interlaced video or not. Mixing interlaced with progressive footage for me is more of a worry that the slight frame rate variation. You may have some slight audio drift or may not. You may see more tearing of the image when panning or not. I'm not really 100% sure as I've not dealt with using different file types. (If the Canon does indeed shoot interlaced video). I have always made sure any second camera I use matches the specs of my main camera before purchase.

Ray.
