In our most recent Tablo firmware update (2.2.20) we have officially decoupled the settings for Recording Quality and Live TV Quality.
Previously your Tablo OTA DVR’s Recording Quality setting affected BOTH live TV streaming and recordings. Now you can choose a different setting for Live TV feeds than you choose for recordings.
We made this change primarily for users of our Tablo Cloud DVR Service (available for Tablo DUAL LITE OTA DVR owners) however, there are several reasons why those using other Tablo OTA DVR models with onboard or USB-connected storage may wish to take advantage of this improved flexibility.

How Tablo Live TV & Recording Quality Settings Work
Your Tablo hardware OTA DVR takes the raw ATSC TV signal coming in from your Over-the-Air antenna and uses a process called ‘transcoding’ to slice it into tiny digital pieces. Transcoding video makes it easier to stream to multiple devices over your home network, and over the internet. (Think of it like turning ice cubes into slush to make it easy to pour.)
These settings now let you independently define the maximum video resolution (SD 480, HD 720, or HD 1080) and bit rate (2 – 10 Mbps) at which your Tablo OTA DVR transcodes your live TV streams and your recording streams.
For recordings, these settings also affect the amount of storage space required for each hour of TV programming. And for Live TV, these settings can affect the length of time a live stream can remain paused before your viewing device’s memory buffer fills up.
When choosing your settings, it’s important to note:
- Higher Resolution Settings Do NOT = Upscaling
Broadcasts being sent to your antenna at lower video resolutions (for example an old episode of I Love Lucy) will not be ‘upscaled’ to a higher resolution if you set your Tablo to 720 or 1080.
- Higher Bit Rate = Nicer Picture, But More Data
Higher bit rate settings can provide a crisper overall picture because the video contains more data. These ‘thicker’ streams can result in buffering on older and slower home networks and will take up more storage space on your local USB hard drive or cloud DVR storage.
- Recommended Settings
The recommended Live TV and Recording Quality settings are different between Tablo devices because each is optimized for the specific model you own. Original 2-Tuner and 4-Tuner Tablo models have recommended settings of HD 720 – 5 Mbps as it’s the optimal blend of recording size, WiFi bandwidth, and picture quality for most users. Tablo DUAL 64GB and DUAL LITE both recommend settings of HD 720 – 3 Mbps which preserves picture quality but helps maximize onboard and Cloud DVR storage/bandwidth use.
There’s also a tuner usage caveat for the 4-Tuner Tablo ONLY when using the highest recording quality (HD 1080, 720 @ 60fps). It’s a bit too complex to explain here so check out our Knowledge Base article on it if you’ve got a 4-Tuner Tablo so you can make an informed decision.
Choosing the Right Live TV and Recording Quality Settings for your Tablo
If you already own a Tablo OTA DVR, you’ll see that the new Live TV setting will reflect the Recording Quality setting you chose previously.
If this setting is working for you, there’s no need to make any changes.
But if you’re just setting up your Tablo OTA DVR, or you’re interested in making some tweaks to your settings, we’ve outlined a few common Live TV/Recording Quality setting profiles:
Cloud DVR Users – High Live TV, Low Recording Quality
As previously mentioned, the decoupling of the Live TV and Recording Quality settings was done primarily for Tablo Cloud DVR Service users. The recommended Recording Quality for Cloud DVR is lower (HD 720 - 3 Mbps) as higher settings could cause failed recordings if your upload speed from your ISP isn’t fast enough to keep up.
Higher recording settings will also use more bandwidth on upload AND playback which will count against your datacap. Even when your Tablo is connected to Cloud DVR, viewing of Live TV is still handled locally by your Tablo so if your network is strong enough, you can use a much higher setting (HD 1080 – 8 Mbps) without worry.
Sports Fans – Highest Live TV, High/Medium Recording Quality
On most networks, sports are broadcast in 720p at 60 frames per second. If you tend to watch games live, the highest live TV setting will retain the full 60 fps which should result in a clearer picture, especially during fast movement. You will need a home network strong enough to handle the throughput though.
Keeping recordings at a medium setting (HD 720 – 5 Mbps) will ensure the rest of your recorded TV shows still look great, without eating up storage space on your hard drive.
Older, Slower Home Networks – Low Live TV, Low Recording Quality
If your router is more than 5 years old or your home network is just sluggish, it’s best to keep both your Live TV and Recording Quality settings low (HD 720 – 3 Mbps). Higher settings may result in buffering during playback.
Onboard Storage/Smaller Hard Drives – High Live TV, Medium Recording Quality
If you’re using Tablo DUAL 64GB’s onboard storage or a small USB-connected hard drive (up to 500GB), you may wish to choose a medium Recording Quality (HD 720 – 3 Mbps) so you can fit more TV shows on your drive. But if your home network is fast enough, you can still enjoy Live TV at a higher quality setting (HD 1080 - 8 Mbps).
Super Fast Network, Large Hard Drive – Highest Live TV, Highest Recording Quality
Got a super fast home network and a 1TB+ hard drive? Feel free to turn everything up to 11! (OK, that’s not a real setting on Tablo, but you know what we mean.) Your cord cutting ecosystem is ideal for Tablo so you can choose to use the highest settings (HD 1080 – 10 Mbps) without worry.
Now that these settings are divided, feel free to play with your Tablo’s Live TV and Recording Quality settings to find what works for you. Note that setting changes will take effect immediately for live TV and future recordings, but recordings made prior to the change will retain the setting at which they were recorded.
