Problem with 4K mp4 on Samsung TV [SOLVED]

[Ron67]

I've spent most of the day searching and trying different options.  I fear I must ask for help yet again.  I have a Samsung Model UN65KS850D which I have played mp4 files on very often through one of the USB ports using a good quality SanDisk 64gb USB 3 thumb drive.  Now that I have PTE AV Studio Pro 10, I seem to be having issues.  Files published at 4K high quality, 3840 x 2160, 60 frames, with hardware acceleration on won't play at all or very little (several efforts made).  If I turn hardware acceleration off, it plays, but jumps frames occasionally, much too often to enjoy watching.  If I drop to 30 frames, it works much better, but not perfect.  I downloaded Handbrake to convert the file, but the settings are over my head.  I have attached the codec sheet for my TV in hopes someone can give me some direction.  The TV has the latest firmware.  I really like the speed of the hardware acceleration, but I read that it uses a higher bit rate.  FYI, "all" the files I have generated today play fine on my PC. I just need to fine tune an output for this TV.

Thanks for any help,

Ron

Hi,

 

the max bitrate of your TV is 60 Mbps and I think your mp4 has higher bitrate.

Try to lower the quality of the mp4 with PTE, the bitrate will decrease.

Note that for the same quality, hardware acceleration  use greater Bitrate.

Thanks for the input, Denis!

I've searched the forum in hopes of finding the bitrate for each of the many PTE settings with no luck.  Perhaps Igor might shed some light on this.  I will be out today, so I'll experiment with the settings tomorrow.

Hi Ron,

I created several test 4K videos with different settings. Can you check them on your Samsung 4K TV? And let me know about results.

Thanks for the help, Igor!  All four files seem to play fine on my TV. 

I did find the drop down on Publish where I can set the bitrate.  I set the bitrate at 60000 and the video is still jumpy on my TV.

Awaiting your guidance,

Ron

Ron,

Did you try default settings? Choose a preset "3840 x 2160" from a dropdown list, High quality, 60p. 

Create a test show from still images. Then try with your real project.

[Ron67]

I did try the default setting with no success.  If I uncheck hardware acceleration, it's better, but not usable.  I am running an Nvidia  GTX 10606GB if that is important.

If I drop down to 30 frames, it's much better.

Ron,

1. Try to set "Medium" quality instead of "High" quality. It will reduce bitrate of video.

2. Just an idea. Try another USB flash drive. Probably your current USB drive is slow? Connect fast USB 3.0 flash drive.

3. I attach a preset for Handbrake video converter. Import it to Hanbrake (main menu > Presets > Import from file) and use to convert 4K video from PTE 10. Then copy to your USB drive for 4K TV.

Thank you for your consistent help! 

I tried the preset for Handbrake (I did have to change the extension to mp4 for my TV to recognize the file).  The results are still jumpy.  I have tried two USB thumb drives by SanDisk.  They are USB 3.0 and pretty fast, but they are identical (two pack).  I will pick up another one Thursday and try that.

I didn't see this problem until I upgraded to the newest 10.0.5 version.  I realize that is probably not the issue, but thought I would mention it.

Thanks for all the help and have a Happy New Year!!!

Update!

I tried different USB 3.1 thumb drives with no success.  I have tried a multitude of combinations of the default Publish choices.  Hardware acceleration seems to be the big variable.  I finally played with the custom settings and everything seems to work fine now (with HW acceleration) .  Even though my TV is rated at 60Mbps, I found a setting of 59Mbps to be more consistent. Playback would be choppy at 60Mbps.  I have had little success at 60P, but 30P looks fine.

Thanks for all the help and Happy New Year!

Ron,

Good to hear that you found partial solution.

If you have iPhone 8 or newer, try to play recorded 4K 60p video on your TV. I can send you test video files later.

[Ron67]

Thanks, Igor!

[Ron67]

I've spent a lot of time trying to get everything working through the USB port, but it's just not happening.  I finally opted to run a 50' high speed HDMI cable from my desktop to my audio system (which is 4K HDMI switch also).  I am pleased to report that I am able to view files published at 60P, high quality and using hardware encoding.  I am finally very impressed with the superb quality of the output from this software!!!!

Ron,

Did you try to play iPhone 4K videos on your Samsung TV? I can send you sample files.

Also try to use an option Video for mobile devices in the Publish menu of PTE and in Custom mode type 3840 x 2160 pixel resolution. Untick the "Hardware acceleration" option. Start the encoding.

Let me know about results.

[Ron67]

Thanks, Igor!

I read where you are very busy getting the Mac version finished, so I really appreciate you taking time to help.

I did not try the iPhone 4K, but I did try the Video for mobile devices.  It worked great, but the default quality was not quite good enough, so I upped it to 100.  The results were very good.  I then lowered it to 80 and used hardware acceleration with very good results with the exception of one slide which has a lot of effects.  I'll gladly omit that slide to gain the speed of hardware acceleration.

I also tried the quality settings under HD and 4K Video with near exact results.

The main problem I'm having now is getting over looking at that Sony Master A9G Oled, lol. 

Thanks for all your work,

Ron

Hi Ron,

I'm glad that it worked for you. I plan to check again parameters for 4K video encoding. It will take some time.

Try to set "150" quality in Custom mode, it will increase visual quality (and file size).

[Ron67]

I did try 150, with no success.  The file was indeed large, but the playback was very jumpy/jerky.  I'm sure you will get it refined!!

I'm enjoying the program and looking forward to future improvements!

Ron,

Try a new version 10.0.6 Beta:
