TS file to MP4 and MKV. Playback on USB stick on Samsung

Have VideoRedo6. When I edit out commercials of a TS file and save to mp4 the playback on my Samsung has stutter but the MKV is fine but not on desktop? Saving to TS file I find there's a slight audio synch issue so that's why I tried the mp4 and MKV containers.

Windows 10 using Movies and TV player and VLC player which are slow to find frames during playback. The video plays fine inside VideoRedo
Samsung Model: UN60KU6300FXZA

If I capture a video stream (TS) there is always an audio sync problem...200-250 ms.
Have you done a "Quick Stream Fix" ?

Yes the first thing I do. I still have the master .TS file and the project file with the cut points to save to a container that will playback on my TV. Like I mentioned the mkv is perfect but on desktop it's all pixelated

Why would anyone encode to TS for delivery, even to one's own teevee?
TS is an acquisition format, and as such is just loosey-goosey wrt structural contstraints, including sync, GOP discontinuities, indexing, and a whole lot more.
The correct delivery format is, an always has been Program Stream.

There is one thing about TS files...
Capturing with OBS as a TS file will allow the file to survive a crash and still be usable. A MP4 file would be unusable.
I found out the hard way after recording all night.

Just sanitize and encode your captured TS files to PS in VRD. TS is an acquisition and pipeline format; PS is a delivery format. Darned good reasons for each, but the internet purists are just plain wrong.

Thanks for explaining which formats to use. Is there a way to save to program stream without a recode?

My Hauppauge capture card saves to .TS

Saving to mp4 has never worked

There's a third option which is M2TS I think which have not tried yet.

"Saving to mp4 has never worked" is this in reference to your recording device or VRD6?

If your TS file "contains" MPEG-2 then I would expect no recode.
It almost certainly does not.

-------------
TS etc are containers and can have the following content (per VRD6)...
(they also vary in what they will accept or not in the content...subtitles, audio type etc)

TS = MPEG-2(NOT 1), H264/AVC AND HEVC.
M2TS = SAME

MP4 = MPEG-2 & 1, H264/AVC AND HEVC

PROGRAM STREAM = MPEG-2 & 1
---------------

So MPGs would tend to need a lot more space for equal quality (H264).
I take an average dvd.mpg of 5-6 Mbps down to a 1.3 Mbps H264.MP4 file. So 25% or less of original size.

HEVC is supposed to be twice as good as H264 at equal size or half the size at equal quality.
BUT according to DEV Dan203 here that is ONLY at high bitrates.

At 1.3Mbps level H264 will win in quality and my testing/eyes agree with that.

I would not use the media player that is built in to TV's at all, because they have always had some issues with various containers.

I would suggest purchasing a stand alone media player instead, which you then can hook directly up to the TV or AV receiver via HDMI.
These stand alone media players are constructed to eat practically all types of media files they are served with.
If you have a Google account and get something like an Android TV OS media player, then you can download VLC from Play Store.
On that area, there the Xiaomi Mi Box S has gotten some very good reviews in tests and then its even a very cheap media player.
