I bought a new Action 4 to suplement my V1 Pocket.  Did some test shooting last night and this morning, both indoor and outdoor.

I tried 4k/30p, 4k/60p, h264 and hevc(h265) with rocksteady.  It is just not as crisp on a 4K TV as my 4 year old 1/2.3" Pocket.    My dog is just fuzzy (somewhat less under super bright light) and patchy under lower light (not even dark).  The building edges are not as well defined.  You can count the dog hair on the Pocket video at night.

I checked the bitrate with mediainfo.   The V1 Pocket has a constant 100Mbp video stream, while the Action 4 only has 60-80Mbp.   Is there another setting I missed?  I have already turned on the Pro mode.

BTW, I first use old an sd card (A1?) from the Pocket (which never had problem writing long video at 100Mbp) and the Action 4 complained about being too slow.  Could the camera have switched to a lower bit rate mode?  I put in a new v30 card today, and the warning is now gone.   Maybe the camera needs a reset somewhere to forget the lower bit rate?

I went on a little hike in a canyon with the Action 4.  All the tree & lush vegetation push the bitrate to 110-120Mbits/s and with good details.  Took more night videos at South Coast.  The bitrate was only about 60-70Mbits/s and was a complete fuzzy mess.  So the camera uses variable bit rate, which is fine.  But other than under bright outdoor lighting, EIS is unless.   The camera goes back to Best Buy

Hello, there. We're sorry for the inconvenience that it may have caused you. May I ask for a separate sample video captured by the DJI Action 4 and DJI Osmo Pocket for further checking? You may consider using Google Drive or Dropbox and provide the link here. Please keep us posted on the latest progress.

I took the dog to a shopping mall (pretty empty on a Monday night) and took some videos with both cameras.  Here is a link to the iCloud-drive.   I think the lighting is somewhere better than the ones I took on Saturday night.  I still need to to find a way to cut  the other video without re-compression.

Sorry.  I returned the Action 4 and then went on a 3 week southern European vacation and just returned yesterday.

The v1 Omso Pocket still worked well and recorded some stunning videos.  I think I will start to save the money for the new V3.
