Troubleshooting
Content Hub is currently supported on the Google Chrome browser only.
For best results, please upload H.264 video. The fast start flag must be set in order to provide playback in the Content Hub player. Your encoding software or NLE should be able to add the Fast Start flag. See below for an example `ffmpeg` command to add the fast start flag from the command line:
`ffmpeg -i <proxy file> -movflags faststart <output file>`
Please follow the following steps if you get an error message while uploading:
1. Take a look at the transfer window to make sure that uploaded file names show up in transfer queue. If they are not present, it means that the Aspera transfer was not successful. Restart the browser and try the upload again.
2. If the Aspera transfer view shows failures, go to this help page to troubleshoot the Aspera Connect issue.
3. If you are not able to troubleshoot using steps 1 and 2, please email the support team with a screenshot of the error in Content Hub and all the Aspera connect logs.
How to see the Transfer view and Aspera connect logs:
Use this help page and follow the steps. To get the show view, go to Window -> Transfers in menu item of Aspera Connect app.
DI Asset Frame Sequence ZIP Spec
Frame sequences for DI assets no longer need to be placed into a ZIP archive. Please note that the requirement for a checksum.txt to accompany the image sequence still exists and the checksum.txt file can be created by using the following command in Netflix Packager (aka npack):
npack checksum -s source folder
For more information on how to deliver DI assets using the new Zipless workflow please review Content Hub - Zipless Delivery of DI Assets.
Original Capture Asset Frame Sequence Zip Spec
Frame sequences for Original Capture Assets should be placed into the ZIP archive with a checksum.txt file that lists out all of the md5 checksum of the archive’s contents. The ZIP file should be a flat listing of files, and not include sub directories.
For more information on how to deliver Original Capture Assets review Content Hub - Preparing Original Capture Assets.
