bug description
I'm a video editor and my issue is that whenever I download a video using cobalt, I'm able to import it into Adobe Premiere Pro with no problems, but I'm unable to import it into MAGIX Vegas Pro (I am using version 14.0; I'm aware the latest stable release is version 21, I'm using 14 for reverse compatibility purposes). I do not have this problem with audio, as it imports just fine.

reproduction steps

download video (settings: 1080p max, h264/mp4, progressive)
open Vegas Pro 14
start a new project
drag file into the project only to see my cursor turn into the "no" symbol (🚫) as it doesn't allow me to import the file

platform

OS: Windows 11 (version 10.0.22621)
browser: Google Chrome
Chrome version 120.0.6099.227 (Official Build) (64-bit)
Vegas Pro version 14, build number 161

Could you try remuxing the video file? Use this command: ffmpeg -i videonamehere.mp4 -c copy outvideohere.mp4.

(ffmpeg is needed)

Remuxing would only be a patch to the problem, but so would downloading
videos from y2mate - no remuxing necessary. Does cobalt do a certain type
of muxing that messes with the usability of the footage?

vegas pro is severely outdated and doesn't accept modern file types, i suggest you use up-to-date software such as premiere like you mentioned

this happens because cobalt merges video and audio files together on-fly, making it impossible to predict final file length, so the length info is missing from file headers (that are obviously sent before the end).

all modern software doesn't have issues with that, but vegas pro hasn't been majorly updated since early 2010s with incremental updates not fixing core problems.

updating to latest vegas version might fix the issue, but it's just a guess based off release date.
