Problem Description
Game/App Problem: every game probably
Error Type: no visual
Video Editor: Vegas Pro 12
Description:
Every Timeshift recording i do with version 1.27.2 ends up in missing visual, which only leaves sounds and my mic for editing. It has happened with every game i've tried so far which include L4D2, Rocket League, TF2 and GTA San Andreas. Some of the clips can be watched in Action's built-in player except L4D2, which gets screwed up. All of the have them same problem when opening in Vegas though: No video, only sound. I have no idea what causes this. I will upload screenshots to make this clearer if needed.
It would seem like this happens with every version from 1.27.0 onwards. 1.26.1 doesn't have this issue.
UPDATE: Thx to the latest versions, the corruption has spread to version 1.26.1. I'm highly disappointed right now.
UPDATE 1.5: Timeshift is officially broken! I just tried it on version 1.26.0 after reverting so far from version by version from 1.27.2 and now EVERY Timeshift recording is corrupted regardless of what version i use! I'll try removing Action and deleting EVERYTHING even remotely related to it. I'll try again after that if it could help.
UPDATE (10/18/15): I don't know how but it started working again. I was messing around with my GTX version in the Device Manager and after an attempt to update it and instead my laptop accidentally removed it, resulting the GTX itself becoming absent. Luckily i got it back manually and managed to update it back via Geforce Experience. I reverted both Intel HD and GTX updated from Device Manager bcs it just looks for outdated versions for some reason. Despite my BIOS still probably being outdated now (which is also a long story), i tried Timeshift. To my surprise it actually saved some files properly.
EDIT TO LAST UPDATE: I spoke too soon. Timeshift saves files but still no video when imported to editor. I'll make a new sample video if necessary.
