^Remedy for Jerky playback after rendering?

[Daguerre-47]

I've been filming scale jet-aeromodels which means mostly fast action. My camera was set to HD (1920x1280) with 25 frames/sec progressive. My computor works with Win 10 pro, 64bit on intel i7-2630QM, CPU @ 2,00 GHz. 24 GB RAM. SSD harddisk for my programs.

Playing back sequences from the timeline, that is on the program monitor, the action is nice and even, but after rendering fast motion is jerky and wing edges on the models are sometimes pixeled. I've tried a couple of different rendering modes but the outcome is the same. I guess it would have been better to film with 50 frames/s interlaced  but now I'm stuck with what I've got and I'd hate to toss it all away. Anyone got a solution to my problem?

How about a dialog box of your rendering settings? And by rendering, do you mean previews within PrPro, or exports out of PrPro?

Hi Neil!

By rendering I mean exporting media. I have tried some different settings f.i.

1) "Match sequence settings".

2) If I leave that box unticked I have chosen FORMAT: H.264, PRESET: Match source - High bitrate, and further down: "Use maximum render quality

On a side note: In Premiere rendering means making preview files and Export is making an output file.

If you pan or tilt too fast in 25p that can be problematic.

Post screenshot of export settings with left tab open to output and visible image.

And screenshot of a clip in Mediainfo in treeview.

Hi Ann,

Thank you for correcting my terminology, to cite Paul Simon from one of his latest songs:"...Ok, new kid in school, got to follow the rules got to learn the routine.."

Please look at my answer to Dean.

Not that much correcting but rather to avoid confusion.

Dont use Match Sequence settings, as said before it uses the wrong codec.

Pick a Youtube or Vimeo preset.

As i gather its your smart tv that is giving the issue. Not Premiere.

Hi Peter,

To clarify, sounds like your rendered video play poorly outside of Premiere.

A few questions:
1. How long is the video?
2. How big is the file?

3. What is the bitrate settings you have for the exported video?4. Have you changed the speed of your initial video?

If you have a long, big file, it could be that your computer or media player is not handling it well. You could try render just 5 minutes of the sequence timeline to see how well that plays.

Hi Dean,

Thanks for taking an interrest in my problem. Answers to your questions are as follws:

1) 43 minues

2) Rendered with "Match sequence settings" it is 8,3GB

3) If I use "Match sequence settings" there is no info about bitrate (that I can find)

     If I don't use "Match sequence settings" I have used FORMAT: H.264 and PRESET: Match source - High Bitrate

4) No.

I've just exported a 4 min long sequence with the same result, BUT! I have just discovered that the jerky and pixeled playback shows on my fairly big "smart TV" screen some, 2 or 3 years old, but not when viewed on a smaler regular TV-screen a couple of years older! Even playd directly from the camera through a HTMI cable the jerkyness shows up on the "smart-TV" but not on the other. And not when viewed on my computer, so there seems to be an issue with the so called smart-TV in regard to my produced films but not when I view ordinary TV programs.

Hi Peter,

If your video plays OK on your computer and on one TV but not the Smart TV, it is more an issue of the Smart TV. That said, you could format your video in a way that is more compatible.

An 8.3GB file is much too large. It means that the export settings are higher than needed. You should lowering your bitrate. See the screenshot below. Under Bitrate settings, choose VBR, 1 pass and then a Target Bitrate of 6 and Maximum Bitrate of 8. VBR is Variable Bitrrate and is generally better than CBR - Constant Bitrate. Can explain more about this if you'd like. You can choose VBR, 2 pass, which may give a somewhat better result than 1 pass (but could be negligible). 2 pass will take double the time to render than 1 pass.

Under Advanced Settings - Key Frame Distance, I'd suggest 25 if your frame rate is 25. Otherwise, match it to the frame rate.

Here is a video on export settings that could be helpful. It hives higher settings than what I've suggested.

Hi Dean,

Thanks for a very informative answer. I looked at the link to gaming careers and, as you noted, he uses higher settings fot the bitrate than you suggested so I tried something in between. Sadly the result was just as before played on my smart TV. So I took the file to one of my sons and we played it on his TV (not a "smart" one) and it ran nice and evenly. Obviously there is an issue with my smart-TV but could there be an issue with other smart-TV's as well? Hobby people sometimes buy my films and I want to be sure that my film will show up nicely on modern TV-screens. So I plan to visit my other son who has got a "smart-TV" and see how it all works out. I'll let you know.

Hi Peter,

What make and model is the smart TV that is giving problems? You could do a search to see what video formats it supports and that may give some insight to why it is not playing well.

[excited_Genie16B8]

Make sure you turn off all processing on the TV, things like Noise Reduction, Motion this, Dynamic that, etc.  Just turn 'em all off.

[R Neil Haugen]

Great point. Most "smart" TV's do stuff to really mess with the image anyway ... to "enhance the viewing experience" ... and should have most of that crud turned off just to see when you get fine production values in the media.

YEESS!!

Thanks Neil, Jim, Dean and Ann for leading me to the solution.

I read the manual even more carefuly than when the TV was new and I suspected that the HDMI-cable from my digital TV-box and the HDMI-cable from my Pc should swap places. Then my TV suggested an upgrade of firmeware, which I did, and last but not least I checked that no enhancements were on, and what do you know! The film with the export settings suggested by Dean ran perfectly!

I've always thought that "smart" in "smart-TV" referres to the TV but now I realize, with embarrassement, that it referres to the users capability to handle the product.

From Sweden with love

Hi Peter,

Thanks for sharing outcome and am very pleased you have a resolution to the issue.

Wish you all the best with your future video endeavours.

[Daguerre-47]

Thanks Dean,

Don't be surprised if you hear from me again in the future. 🙂

We hope we do! And as you pick up some knowledge in your specific areas of knowledge, if you could see to help out with others that would be awesome.
