Automated Video Checking and Intelligent Automated Correction
- VidChecker is 2nd Generation - QC checking and intelligent correction
- Thoroughly checks file, video and audio parameters
- Older "1st Generation" file checking systems only do QC checks – VidChecker also intelligently corrects common video and audio problems including loudness - Higher throughput and processes faster
- Automatically takes advantage of multi core processors
- Each VidChecker license 4 processes 4 files at a time (VidChecker POST 1 file at a time)
- Expandable with multiple licenses per PC and multiple PCs in a VidChecker Grid - Easier to install, use and integrate
- Designed for video operators to use and understand
- Browser based GUI – multiple users
- Can move files in workflow on pass / fail / correction – simple dropbox (hot folder) operation
- Designed for easy integration with asset management / automation systems (SOAP API)
- Lower cost
- Affordable by all organisations, and can also expand to largest requirements
