Media offline is a term used to describe the situation where a portion of a content is inaccessible or cannot be played due to a technical error, a missing media segment, or other reasons.
How does this happen?
One
of the most important steps during the post-production process for a content is
‘Editing’. A typical editing project comprises many media clips and segments
that are stitched together in the timeline, in order to create the complete
content. A professional editing solution keeps references to all these segments
and allows publishing of the final render once the editing process is
completed. These media segments can reside in various storage such as SD-Card,
SAN, NAS, USB, HDD, etc.
Imagine
a scenario where a fresh piece of content is received on an SD card. The editor
inserts this SD card into the Editing software and adds the media files on the
SD card on to the editing timeline. It looks all good at preview and the editor
saves the project. The editor comes the next day, removes the SD card while
continuing to work on the editing project. On previewing the file, the editor
suddenly sees “Media Offline” image in the video. This “Media offline” image is
inserted by the Editing solution when the referenced media is not accessible
due to the removal of the SD card. This can also happen if a media file is
deleted, moved, renamed or simply becomes inaccessible in a network storage. It
can also happen due to slow access to the storage. The actual “Media Offline”
image also varies across different editing solutions.
Here
are some examples:-
Unfortunately,
human mistakes & network issues continue to happen in the editing
environment and therefore, such a scenario is common. However, the presence of
“Media Offline” segments in the final content delivered out of the
post-production process is completely unacceptable. Its presence will lead to
content rejection, thereby damaging the reputation of the post-production
house. If the issue is detected in time before delivery, rectification is
fairly easy as it is only a matter of providing correct reference to the
missing media file inside the editing solution.
How to rectify “Media Offline”?
Comprehensive
rectification requires timely & accurate detection of “Media offline”
issues in the content. There are two ways of detecting media offline: manual
and automated.
Manual Method to Detect Media Offline
The
manual method involves an operator manually checking the content to determine
if the “Media Offline” image is present in the content. The image can be
present for a few frames or for a longer duration, depending on the length of
missing content. This will require an operator to watch through the entire
content, which can be a time-consuming process and is prone to human errors.
Automated Method to Detect Media Offline
An
Automated QC solution can detect “Media offline” in the content without any
manual intervention. An operator just needs to configure the template in the
video QC software and the rest is done automatically. This test by the video
quality checker software is also accurate and therefore, can be relied upon
without a need for a manual scan. Using an Automated File QC solution for this
detection is faster and more efficient than manual methods, thereby helping
optimize the content workflows.
Pros and Cons of Manual and Automatic Methods
There
are hardly any cons of using Automated methods, as the investment in QC
software is easily offset by the cost savings by eliminating manual
intervention.
Venera
offers a wide range of Automated QC solutions – both for on-premise (Pulsar)
and Cloud deployment (Quasar).
Quasar & Pulsar are
perfect solutions for automated media offline detection, allowing you to detect
and fix media offline issues quickly and efficiently. This helps minimize the
impact of such QC issues on production timelines and budgets while retaining
the reputation of the post-production company.
By
relying on Quasar & Pulsar, post-production houses can be certain that
content delivered by them to their customers is free of “Media Offline” issues.
Venera’s
QC solutions are also highly customizable, allowing users to configure them to
their specific needs and requirements. Users can choose to invest upfront in a
QC software license or can pay on a usage basis. With these options available,
using a QC solution to detect and eliminate Media Offline issues efficiently is
easy & feasible for everyone.
