@BONLEV Please post Mediainfo report for the media on your Vegas Pro timeline. Also, upload a sample of the offending media to a cloud share such as Dropbox, OneDrive, Google Drive, etc. and post a link here on the forum. There have been media decode issues in various Vegas Pro versions with various different sorts of media.

I recorded a sample but I couldn't hear the noise in that sample. very strange so I would not share it.

I shared 4 mediainfo files: from my current project I used the sony NX800 and sony FX6. Lots of noise during playback in vegas and also noise (but less noisy) when playing outside of vegas.

I had some samples from a A7IV and a gopro 7 black. Both plays fine without noise outside of vegas.

I can hear a slight noise of the A7IV inside vegas and a slight noise of the gopro inside of vegas.

Scrubbing through the timelime is also noisy (maybe this is normal?)

I just rendered the first part of my stage show I had filmed in vegas 21 build 315. On several parts of the sony FX6 (global view) the footage is stuttering in the final video. Not in the close ups of my hxr-nx800.

I thought I go back to the previous build but my project was already saved and it won't open in that previous/older build.

So I took the risk to buy the version 22 (the trial would not me render more than 2 minutes) but the problem with the noise and the stuttering is still there.

I recorded with my phone my screen. (no audio in this sample)

The strange this is if I render a part of the project (about 90 seconds for this test) there is no stuttering...

But cams were on 25p (checked it). It is the first time i have this issue.

no one? 🙁
