Video Specifications


There are many ways to encode video. Here are some video specs we know work with OnCue. The first one will be spelled out so you know what number goes where and then we’ll just give you the specs. We have also added some pretty pictures to the bottom of the article with screenshots from TMPGEnc Video Mastering Works 6 made by Pegasys.


IMPORTANT: Always use a CONSTANT Bit Rate NOT Variable.

Standard Fullscreen Aspect Ratio = 4:3

Standard Widescreen (SD and HD) Aspect Ratio = 16:9

Audio for All video specs below is Audio Layer II, 44100 Hz, Dual Channel Mode, 224 kbps

Frames Per Second (fps) = 29.97 or 30 for all videos

NOTE: You can play with horizontal and vertical size as long as you maintain the ratios


  1. Video:  MPEG-1, Standard, Fullscreen NTSC, 352 X 240, 29.97 fps, 1500kps

Video layer:
format = MPEG-1
horizontal_size= 352
vertical_size = 240
frame rate (fps)= 29.97 frame/s
bit rate = 1.5 Mbps or 1500 kps

Audio: MPEG-1, Audio Layer II, 44100 Hz, Dual Channel Mode, 224 kbps

Audio layer:

format = MPEG-1 - Layer-II
bit rate = 224000 bit/s
sampling rate = 44100 Hz


  1. MPEG-4 (Widescreen) 720x408 29.97 fps 2500 Kbps or 1500kps (to reduce file size)

Video Stream Format = H.264
Entropy coding = CABAC


And now...the pretty pictures and more detail...


The edit window in TMPGE will show you the properties of your video and the settings that were used to create the video file. This is important to note when you are trying to figure out what type of video file you have.


The settings screen for your video is vitally important to have a properly encoded MPEG-1 file. Circled in red, you will find the settings that are optimal for OnCue to play your video without any errors. Encoded video at 1.5 MBPS for the bitrate will produce a file that looks perfectly fine for deposition video. However, if you want better quality, you can up this level to 2.5 MBPS, but you do not want to go higher than that. If these settings are used on your video file, you will export a working and solidly encoded MPEG-1.


When choosing to use MP4 (MPEG-4) as your video format, you will need to use the H.264/AVC video stream format.


The MP4 settings are almost the same as the MPEG-1 settings. The video MUST be encoded at a CBR rate of 2.5MBPS or 1.5 MPBS (if you want to reduce file size) and the stream format MUST be H.264. It is also important to make sure that the Entropy Coding is set at CABAC.



Both of these settings, for MPEG-1 and MP4 can be saved in TMPGE by clicking the Save Button in the lower right corner of the properties screen. This makes a very easy way for you to get to these same settings for all of your future encoding jobs. The saved file will be in your Custom Output Templates section in TMPGE.
