1. Video quality
- There are two options in terms of quality that you can choose to get for converting your video cassettes.
A. Known as a "Standard transfer" .
B. Known as a "Professional transfer".
1A. Standard transfer
- The "Standard transfer" is recommended for those who don't exactly value the quality of the picture as long as it looks reasonably good. It is also recommended for those who have limited storage. *All video files using "Standard transfer" will use come out as a ".mp4" file but this can be converted into the customers intended video format.* Refer to "2. Supported file formats" for more information.
- The average size of a digital video file using a Standard transfer is around 1 gigabyte per hour.
Video specs
- Codec ID: M4V* Unless converted to another desired video format
- Format: MPEG-4* Unless converted to another desired video format
- Video bit rate: 2 314 kb/s
- Frame rate: 29.970
Audio specs
- Format: ACC LC* Unless converted to another desired video format
- Codec ID: mp4a-40-2
- Bit rate 216 kb/s
1B. Professional transfer
- The "Professional transfer" is recommended for those who absolutely value stuff like high bit rate and proper deinterlacing. As a reasonable compromise between bit rate and disk space the video is encoded using x264 at a CRF of 12 using zero latency. Audio is uncompressed PCM. Video is also deinterlaced using QTGMC in Avisynth. *All video files using "Professional transfer" will use come out as a ".avi" file but this can be converted into the customers intended video format.* Refer to "2. Supported file formats" for more information.
- The average size of a digital video file using a Professional transfer is around 5.9 gigabytes per hour.
Video specs
- Codec ID: H264* Unless converted to another desired video format
- Format: AVC* Unless converted to another desired video format
- Video bit rate: 12.3 Mb/s
- Frame rate 59.940
Audio specs
- Format: PCM
- Codec ID: 1
- Bit rate 1,536 kb/s
2. Supported file formats.
- While there are options for using any of the previously listed video formats with the exception of ".mp4" for "Standard transfer" and ".avi" for "Professional transfer" all other video file formats will require the use of re encoding during the conversion from there original digital source in order to meet the customers intended video file format. As such the video may loose some quality during the re conversion process. For those using "Standard transfer" this shouldn't be much of a worry as the quality loss is negligible. For those using "Professional transfer" it's recommended that there be no video file conversions in order to preserver the original quality of the master digital file (unless it involves changing out video containers).
