4K output to TV problems
I make 4K sports videos for a small high school. I export the final video at about 1 GB/minute (probably more than what I really need). I save the videos to a jump drive for distribution to the coaches/players.
The video will play just fine on my computer with a 4K monitor. But on my 4K TV, it always takes 2 or 3 seconds before it will start playing the video smoothly. The sound plays normally, but the video starts out in slow motion, then for a very short spurt will play very quickly until it gets ‘caught up’ and then is fine. Today I made a video that took about 5 seconds until it was playing smoothly.
I’ve tried reducing the bit rate to some degree, but that didn’t help. Any suggestions?

If you are playing from a thumb drive, that might be your problem.
Cheap thumbs are slooow. The TV is probably spending that time buffering from
the thumb drive. Use a faster thumb drive or better yet, an SSD. I am assuming that you are using your TV’s internal media player in any case. Check your manual for the TV’s internal media player specs. These are often more restrictive than you might expect.My general recommendation is to use an h.264 “Vimeo” 4k export preset to make playback files for any device. These presets are both high quality and highly compatible. In fact, I upload to Vimeo so I can use the Vimeo app for playback to my TV rather than schlepping the files around. In my case, I’m playing from a Fire player, but many players and TVs have a Vimeo app.

Not too many consumer televisions have that kind of read speeds.
In the past, I had to deliver tons of odd files via USB and in the end, I got a few of the clients to buy PS3s and just load it on there for playback.
PS3s used were going for dirt cheap around here.
Now, as far as 4K I am sure there are better options.
Does the TV have a data drive? Can it access any network?

My TV doesn’t have a data drive, I’m not sure about whether it can access ANY network–but it’s not MY TV that I’m all that concerned about, it’s what the players will use at home, so maybe I’ll just have to be content with a few seconds playing slowly.
It’s just at the very beginning that it lags, after that, it will play at regular speed for the entire game. There has just been one file where the lag lasted about 10 seconds that really bothered me.
I do have an external SanDisk Extreme SSD drive, but it still has to connect to the TV via USB 3, and the lag time is exactly the same with the SSD as with the 3.0 jump drives.
These are given to the players in the anticipation that they will watch these for years to come, so maybe by that time, they will have devices that can play it flawlessly.
Thanks to all who took the time to help out.

The lag is def the target display.
It has to load (buffer) first.
