@Scokljat They may not be true 30fps, perhaps they are variable frame rate, mediainfo will tell.

Usually 30fps = 29.97fps but do show us MediaInfo.

@Scokljat They may not be true 30fps, perhaps they are variable frame rate, mediainfo will tell.

Yes, you're right. Thanks! All source video files report as variable frame rate in media info. Now, what can I do about this issue? Is there some way to make them all play at 30FPS without any interpolation? I mean, like converting all videos to image sequence and then play every frame on it's place at 30FPS project? Videos will play little bit faster but motion should be fine, right? And I don't need audio, so no need to stretch.

On my phone, now I see the option to record video as "FHD" and "FHD 60fps". I used "FHD" option. Maybe using "FHD 60fps" means fixed frame rate? Will try latter, but, current footage is already recorded at variable frame rate and I cannot re-record.

Thank you very very much for your prompt help :-)

@Scokljat I made up a simple util VFR2CFR, based on, and needs ffmpeg downloaded and added to the Windows PATH. Click my signature to access the download link. Handbrake and wwaags HOS will do it also. Just select the output FPS.

Thank you all for your help. I'm amazed on ultimate level of support I got here. Really thank you guys :-) I'm gonna close this post with suggestion of recompress from VFR to CFR 30fps. However, I'm not happy (my mistake) as I tried to avoid recompression. I actually didn't know VFR even exists. Why should one need VFR, BTW?? This videos are unusable for anything more than watching on smartphone or PC. I see lot of people use high end smartphones for recording of Youtube videos and then edit and render in some video editor such as Vegas or Premiere. How do they manage VFR to CFR? Recompress or interpolate? Ah.

Thanks and best regards.

I actually didn't know VFR even exists. Why should one need VFR, BTW?? This videos are unusable for anything more than watching on smartphone or PC.

If not much is moving, fewer frames / second are recorded. That is irrelevant for the quality - but it saves a lot of storage space.
Otherwise - with the many videos that are made on smartphones - the memory cards would soon be full.

99% of these videos are only viewed on the smartphone - and that's no problem. Who would do the effort with post-processing ??????😕

I just came across this problem today, and have been searching the forum. I was trying to edit a short clip shot on my iPhone using the 4K 24fps setting, my project is 23.976 and after rendering the project with a frame rate as the project the video was all jacked up. This is when I noticed that the source media properties frame rate was 25fps PAL. I was able to render it some what acceptable video after disabling the resampling but still not completely satisfied about this issue.

After reading several post and found out about the VFR issue. I tried hand break but when I set it to constant rate of 23.976, same problem, and Mediainfo also still states that it is VFR for the new file. When I set hand break to 24 constant it then shows it as 24fps Film in Vegas. My question is will this cause an audio sync problem when rendering longer clips? Plus these files are giant compared to the original.

Also why does Vegas default to 25fps PAL for VFR files vs. defaulting to 24 Film or even 23.9? Its not like the variable rate ever goes higher than 24fps after the hand break conversion, so why does Vegas interpret it to be 25fpsPAL?

@KelvinWorks “shot on my iPhone using the 4K 24fps setting”.

So its basically 24 fps VFR. You should ideally use a Vegas Pro 24 fps project setting to get best results, and render out to a 24fps clip. The util I mentioned in my previous post will convert it to 24fps CFR clip. The final size will be determined by how high a quality setting you select. The later versions of VP handle VFR pretty well without any conversion.

The other day I shot 60 fps uhd footage on my Samsung phone, VFR output of course. I didn’t bother converting it, I just loaded it into vp18, latest build, applied mercalli for stabilisation, did some pan crop, rendered it out to 60fps FHD, no problem.

Hello,

I have the same problem with a Crosstour Camera in 4K 50fps, in 1080p it's constant.

I do not understand that Magix does nothing about this because with other software I do not encounter this problem. It's still a shame to encode everything with third-party software. This problem may cause me to switch to another software in time because it becomes tedious (takes up more space and takes much longer). For information I am under Movie Studio 17 Platinium.
Thanks for HandBrake, it saves me for now.

EDIT:
Finally HandBrake gives me very large files and Movie Studio has trouble processing the preview. It becomes distressing,

I regret my MAGIX purchase ...

@KiKoMaSo VP 18 and some earlier versions handle VFR very well. If I have only a small amount of phone footage I don’t convert, using VP18, even though I can using my own util. Maybe MS17 Platinum isn’t as good as VP at handling VFR?

“HandBrake gives me very large files”

Using my util, (and i’d guess with other software) it’s possible to vary the output file size and quality to match your needs.

@KiKoMaSo My experience is that VMS handles VFR okay if the variation isn't great. But if the framerate varies greatly it may struggle. Given VP is a Pro level, and much more expensive, programme I expect it will handle VFR better.

You could download the 30 day trial of Pro to see if it handles your material any better.

I made a refund request which was immediately accepted following this problem. (great service 👍)

I will see to test the other versions offered by Magix but Vegas Pro is expensive for my use, so I still have Video Deluxe.

I wonder what are the big differences between :
Magix Video Deluxe Premium
and
Vegas Movie Studio 17 Suite (I had the platinum)

Because according to the comparisons it seems to do the same things.
Or, is there a more suitable version for sports, family, movie, etc. videos? ?
I am a little lost.

Thank you.
