Video render issue - footage from Vivo X200 Ultra

Petr-Chajda wrote on 10/16/2025, 11:41 PM

Hi,

I would like to ask for your help - in Vegas Pro 20.0, Built 411, I am experiencing following issue:

When using Vivo x200 Ultra's footage, the rendered file has always significant frame drop no matter what settings I use.

I have tried tick and untick "Adjust source media..:", different frame rates, different render settings (usually I use MAGIC AVC/ACC MP4 Internet HD 1080p 23,976).

Source file is recorded in LOG, 3840x2160, 24 FPS, H.265.

With other media sources such as Sony A7S III, older smartphones S10, Galaxy Notes never any issue.

Would anyone have a clue what is causing this problem?

Try to precisely match the source framerate by setting the project and render framerate to the same number (23.976 for example).

Feel free to share a screenshot of your project settings and render settings for review.

"frame drop" - do you mean that the fps rate is slower than the original video or that video frames are being skipped and replaced with black frames?

"no matter what settings I use' - do you mean the settings in the camera or in Vegas Pro - or both?

From an internet search, the video options available in your camera appear to be:

  • 8K@30fps, 4K@30/60/120fps, 1080p@30/60/120/240fps, gyro-EIS, Dolby Vision HDR, 10-bit Log, HDR10+

With your Vivo video, which resolution and fps rate are you using? Also, do you have Dolby Vision HDR, 10-bit log or HDR10+ enabled? If yes, is there a problem in Vegas Pro when turning off those features?

What would be helpful is if you would upload to this forum thread a detailed MediaInfo report (a free app) of one of the Vivo video media that is causing a problem. More about MediaInfo here which includes a link to download and install the app.

First, thank you for your reply. I will place my answers in the text below.

"frame drop" - do you mean that the fps rate is slower than the original video or that video frames are being skipped and replaced with black frames? When playing the rendered video, the framerate is jerky.

"no matter what settings I use' - do you mean the settings in the camera or in Vegas Pro - or both? - render settings in Vegas Pro

With your Vivo video, which resolution and fps rate are you using? Also, do you have Dolby Vision HDR, 10-bit log or HDR10+ enabled? If yes, is there a problem in Vegas Pro when turning off those features? As I wrote, I am using 10-bit LOG, 3840x2160, 24 FPS, H.265 - no Dolby Vision HDR.

As you proposed, I have also processed the "standard video mode" without any "add-ons", the issue persists.

Yes, I will send the MediaInfo report below in a form of a text.

I edit the footage in the simple Microsoft Clipchamp and these issues did not occurred.

Thank you for your suggestion. I did set the frame rate to match exactly as proposed, but still getting the same result.

I am attaching print screens of the video file properties, project settings and render settings.

Thank you for the detailed reply along with the MediaInfo report.

Typical of smart phone video, the video is Variable Frame Rate (VFR) but the MediaInfo report shows that variance in frame rate is from a low of 5 fps to a high of an incredible 10,000 fps - I've not seen any fps that high before, and very possibly the vast difference in frame rates is causing Vegas Pro grief. Unfortunately, Vegas Pro is not all that comfortable with wide differences with VFR.

The long-recommended workaround on the forum for VFR video is to transcode the video to Constant Frame Rate (CFR) in a free transcoder such as Shutter Encoder or HandBrake. It may also be worthwhile transcoding at the same time to MP4-AVC (H.264) as I usually had problems in Vegas Pro 20 with using 4K HEVC video from my Samsung smart phone.

Thank you for the screenshots. Try these render settings and let me know if the result is any better.

Edit: I see you pasted MediaInfo above

Frame rate mode                          : Variable
Frame rate                               : 24.000 FPS
Minimum frame rate                       : 6.000 FPS
Maximum frame rate                       : 10 000.000 FPS

is not good for editing and agree with Dexcon's advice.

I changed the coding to H.264 in the Vivo camera, still getting the same results.

When checking the VFR on older phones, the range is not that high at all in comparison with Vivo, just as you say.

Using HandBrake made the final output smooth as used to. Unfortunately this seems to be the only option.

 

Thanks to both of you for your inputs, greatly appreciated!
