Video Compression Settings
In order for your work to look it’s best, we recommend these compression settings. As a rule of thumb, the settings below should yield a file size of about 6-10GB for a feature film. Learn how to upload your videos here.
|BIT-RATE:||8,000 kbps – 13,000 kbps|
|FRAME RATES:||23.98, 24, 25, 29.97, 30, & 60 FPS|
|RESOLUTIONS:||We accept any resolution, but please upload the largest you have (without upscaling).|
|CONTAINER:||MP4, MOV, AVI, WMV, etc.|
Please make sure your files do NOT contain any leaders, color bars or tones. The files will be presented to users exactly as they are delivered. VHX CANNOT accept videos with rectangular pixel aspect ratio, Apple Intermediate Codec, or HDV 720p60.
|SAMPLE RATE:||We accept most sample rates, but common ones for video are 44.1kHz & 48 kHz.|
|CHANNELS:|| Stereo - L & R
NOTE: If you want to upload Surround 5.1, please read this guide.
COMMENTARY TRACKS (Secondary Audio) - To include a commentary track on your film, you will need to hardcode the film with this audio track included, in a video editor. This outputted video will be served as a separate video file, in addition to your film.
Once your film is uploaded, we will begin the transcoding process, and you will receive an email when it's ready. We transcode it to the proper sizes and formats for streaming and downloading (depending on your master file):
|1080p MP4 download||Source file must have a resolution of at least 1920x1080|
|720p MP4 download||Source file must have a resolution of at least 1280x720|
|540p MP4 download||Always created|
|360p MP4 download||Always created|
|Adaptive streaming file||Always created|
We accept hard subtitles, meaning they will be need to be encoded within the video with an editing program. We also accept soft subtitles, which are a text file (.srt and vtt only) that we can play alongside your work in the player & as a separate download. Read more here.
- FORMAT: SRT or VTT
- TIMECODE: MUST be in SRT format, like this: 00:00:07,751. Notice that it starts with "00". Other formats sometimes start with "01". This "01" will offset your timecode for SRT by 1 hour in our video player. You can use Jubler to fix this 01 issue by shifting the time. The subtitles need to reference the Media timecode and NOT the SMPTE timecode.
- ENCODING: Make sure the SRT is in UTF-8 format. That works best when displaying foreign characters.
