To transcode an H.265 (HEVC) file to a format compatible with Unity, you’ll generally want to use a widely supported format like H.264 with an MP4 container since Unity has better compatibility with such files. Here’s how you can transcode the file using FFmpeg:
Use the following command:
ffmpeg -i input.hevc -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k output.mp4
-i input.hevc: Specifies the input file.
-c:v libx264: Specifies encoding the video stream with H.264 codec.
-preset medium: Balances encoding speed and file size (you can use ultrafast, fast, slow depending on your needs).
-crf 23: Controls the output quality; lower values mean better quality but larger size (range is typically 18-28).
-c:a aac -b:a 128k: Encodes the audio to AAC with a bitrate of 128k.
- If your input has no audio or you want to strip it, you can add
-an to remove the audio.
- Adjust
-crf for better quality if needed (e.g., use 20 for better quality).
This will produce an MP4 file with H.264 encoding, suitable for Unity projects. Let me know if you need further assistance with any specific settings or requirements!
