A PowerShell script to convert videos to the HEVC video format utilizing GPU hardware acceleration using FFmpeg for Windows.
|
||||
A PowerShell script to convert videos to the HEVC video format utilizing GPU hardware acceleration using NVEnc for Windows.
|
||||
|
||||
The main benefit being that you can save disk space significantly (most of the time).
|
||||
|
||||
|
||||
|
||||
## Space Saving Examples
|
||||
|
||||
- 2.5GB MP4 to 500MB HEVC MP4
|
||||
@ -15,26 +17,24 @@ _Results vary and depend on the input video's format, bitrate etc._
|
||||
## Minimum System Requirements
|
||||
|
||||
- PC with at least 2 cores
|
||||
- Recent NVidia or AMD graphics card
|
||||
- Recent Nvidia graphics card
|
||||
- Enough free disk space for resulting video files
|
||||
|
||||
**VITAL: ALWAYS check the resulting video files, ending with "(HEVC)" for expected length and try them out in a video player checking for quality and smooth playback.**
|
||||
|
||||
## Encoding
|
||||
|
||||
During encoding (conversion) it is normal for high **CPU** and **GPU** usage. Be sure to only run the script when the PC has no other processes hogging up resources.
|
||||
|
||||
The script encodes the files alongside the original with (HEVC) at the end of the filename.
|
||||
The script encodes the files alongside the original with '-HEVC' at the end or inplace x265 replacement of the string in the filename.
|
||||
After the conversion, a test is performed on the new video file to ensure its integrity.
|
||||
If this test is successful, the old file will be deleted.
|
||||
If not, the failed conversion-file is deleted and registered.
|
||||
|
||||
## Decoding
|
||||
|
||||
The resulting HEVC videos require a more powerful PC to decode and playback, than the original would.
|
||||
|
||||
## Script Usage
|
||||
|
||||
1. Download FFmpeg for Windows: https://ffmpeg.zeranoe.com/builds/ (see screenshots below)
|
||||
2. Extract ffmpeg.exe to a known path/folder
|
||||
3. Download **convert_Videos.ps1** and create **video_file_list.txt** alongside it
|
||||
4. Make 4 edits in **convert_Videos.ps1** using PowerShell ISE
|
||||
5. Copy+paste full paths into **video_file_list.txt** and save
|
||||
6. Run **convert_Videos.ps1** to convert to HEVC
|
||||
1. Clone this Repository to your computer
|
||||
2. Download latest NVEnc for Windows: https://github.com/rigaya/NVEnc/releases
|
||||
3. Extract the files to "video-in-place-hevc-converter\encoder\" and replace the old ones
|
||||
4. Edit the $videoPath variable in the PowerShell file to point to your video-files folder
|
||||
5. Run **convert_Videos.ps1** to convert all video Files on the provided path to HEVC.
