Basic Image / Video Review
- Tap the thumbnail or file name of a photo or video to view the file.
- Your photo or video will open up in a new screen.
TIP: If you are playing back a video for the first time, pause the video until the green bar has fully loaded. This green bar denotes transcoding. If the green bar has not fully loaded your video playback will be choppy.
Transcoding Video and RAW Audio
A video or RAW audio file requires transcoding in order to playback for the first time. GNARBOX 1.0 automatically begins to transcode video files in the background when footage is first transferred, but it is likely that transcoding time will need to take place before immediate preview can be expected. Video transcode times can vary depending on a number of different factors. These include:
- Frame rate
- RAW audio
High frame rate and high bitrate videos can take longer to transcode depending on the speed and bitrate they were shot at.
RAW audio can cause extended transfer time as well. Examples of RAW Audio can include:
- Mono audio
- 44KHz audio
- RAW audio frames
- Audio codecs that aren’t standard to h.264 (ie: XAVC-S, GoPro Hero 4 Session, etc)
RAW audio will take roughly 1 second to transcode each second of audio.
Suggested Video Review Workflow
To help minimize wait time, here’s a workflow we highly suggest if you’re looking to transcode a handful of clips:
- Insert your memory card.
- Copy the files you want to be processed over to the GNARBOX.
- As soon as the file transfer is finished, eject the memory card.
- The GNARBOX will begin to preprocess the footage. Wait about 1 minute for every 1 minute of video shot.
If you are trying to edit a 128gb card filled with fresh footage, you should expect longer transcode wait times, but this process will work great if you’re just looking to edit a drone flight or two!
Supported Files: Photos and Videos
You are able to back up any file and move it around within the GNARBOX ecosystem. That being said, a supported file type is one that is capable of being played back or edited within the GNARBOX Classic app.
Note: For unsupported RAW files you may be able to import the file into Lightroom CC or 3rd party software such as Snapseed or Affinity Photo.
Videos - The following formats are unsupported video file types. Please note this list is based on current testing results and could include formats that have not yet been tested.
- AVCHD, XAVC
- Canon MP4JPG MOVs
- 360 video files
- H.265 iPhone Video Recordings
- GH-5 10-bit (note that other bitrates such as 8-bit are supported)
- Mavic 2 Pro H.265 10-bit (note that other bitrates such as 8-bit are supported)
Despite the fact that ProRes files are often packaged in an .MP4 wrapper, the files contained within are not compatible with the GNARBOX’s video transcoder.
XAVC users should also note that XAVC-S is supported, but any AVCHD and XAVC files are not.
* For iPhone h.265 users, you are able to go into the Video Recording settings on your iPhone and change your settings to record in h.264 so that your video is compatible with the GNARBOX. We are working on an update that will allow compatibility for iPhone h.265 in the future.
You are able to back these file types up and move them around within the GNARBOX ecosystem, but playback and editing are currently not supported for these file types.
What an Unsupported File Looks Like
When a file is unsupported, you will be prompted with the following screen:
If you believe the file you are viewing should be supported or if you have any questions, please feel free to reach out to our support team at firstname.lastname@example.org.
The GNARBOX Classic app features a handful of useful gestures. The two main gestures for previewing files include the two-finger tap and the swipe.
When viewing files in Thumbnail view, tap the screen with two fingers to see additional file data including dimensions and file name.
When previewing a file, simply swipe right to left to view the next file. To view the previous file, swipe left to right.
When previewing your files, you can easily select your favorites by tapping the star icon at the bottom of the preview screen.
Once you've selected your favorites, review them by navigating to the Favorites tab.
