Choppy camera movement in Youtube videos

Dreamtime Visions Product · 14th April 2014, 12:37

I am having a very frustrating problem without any clear cause or solution. Camera movement in my Youtube videos (pans/cranes) is choppy/jittery. However, the video in Premiere, exported at 59.97 (for downloadable copy) and 29.97 fps (for streaming), streamed through VLC from Youtube, downloaded off Youtube, uploaded to Vimeo is all fine and doesn't have the choppiness. Every time I upload test videos, I get 'We detected your video may be shaky. Would you like us to stabilize it?' (I say no as the 'fixed' version is horrific). To make it more confusing, only some viewers (roughly half, including me) find it choppy. Some have suggested it is a Flash/browser issue, but I really need something more specific and suggested fixes. I'd just forget about Youtube and upload to Vimeo, but I'm having audio desync issues there (another frustrating issue) and the audience would be more limited anyway.

Watch the following example on Youtube/full screen (not embedded, to me it seems less choppy when embedded).

Example: https://www.youtube.com/watch?v=g2Ri-XAHTIQ&feature=youtu.be

Video and test details below:

VIDEO DETAILS:

1. Original Render @ 120FPS jpeg capture from video game, 1280x720, progressive, square pixels

2. Jpeg -> Avi conversion in Virtualdub at 120 FPS

3. Sequence settings on Premiere @ 59.97 FPS, 1280x720, progressive, square pixels, 48000khz audio, stereo

4. Export settings on Premiere @ 29.97 FPS, 1280x720, progressive, square pixels, max render quality, max depth, 48000khz audio, stereo

5. Avisynth script:

AVISource("J:\Final Render\29.97 fps\SWREP1.avi", audio=false).AssumeFPS(30000,1001)
#deinterlace
#crop
#resize
#denoise
ConvertToYV12(matrix="rec601")

6. x264/AAC encoding through Megui:

TEST DETAILS:

I've run so many tests that I've lost count, all unsuccessful:

1. Tried different codecs (WMV, h.264 through Premiere Pro, x264/AAC)

2. Tried constant FPS (re-rendered footage at 30 fps, premiere settings 30 fps, final encode 30 fps)

3. Tried final encode at 30 fps not 29.97.

3. Encoded at constant quality, variable bitrates, constant bit rates, 2 pass, 3 pass, etc

4. Exported at 59.97 from Premiere and let Avisynth convert FPS to 29.97

5. Different VBV max/buffsize values

6. Different GOP min/max values (15/8, 30/15, 300/30, etc)

7. Different levels in x264.

8. Different megui (handbrake, Microsoft expression encoder)

And the list goes on, you get the idea.

I am really quite desperate for help at the moment. It's a 20 minute machinima and a lot of work went into it. I really don't want to release a choppy video, when as you know people generally won't download a beautiful high-quality, 59.97 fps video file at 800mb even when you request and provide a link.

It's not choppy for me.

I see a little "judder" ("choppy" might be too strong a word)

EDIT the judder on the downloaded video is much less severe, but still present, so let's look at your sources.

>1. Original Render @ 120FPS jpeg capture from video game, 1280x720, progressive, square pixels
1a. Please post a MediaInfo report on a typical capture file.
1b. If possible, please furnish a short sample.

>2. Jpeg -> Avi conversion in Virtualdub at 120 FPS
2a. For importing non-AVI files into VirtualDub, you should (IMHO) not use the default DirectShow input driver, but instead use the VirtualDub FFmpeg input driver or Avisynth+FFMS2.
2b. Are you doing frame rate conversion in VirtualDub? What settings are you using?
.... (hint: use "decimate by 2," not "Convert to...")
2c. Please post a MediaInfo report on a typical VirtualDub-generated file.

>3. Sequence settings on Premiere @ 59.97 FPS, 1280x720, progressive, square pixels, 48000khz audio, stereo
>4. Export settings on Premiere @ 29.97 FPS, 1280x720, progressive, square pixels, max render quality, max depth, 48000khz audio, stereo
4a. Please post a MediaInfo report on a typical Premiere-generated file.

>5. Avisynth script:
(looks OK)

>6. x264/AAC encoding through Megui
6a. Please post a MediaInfo report on a typical Megui-generated file.
6b. If possible, please furnish a short sample.

One suggestion: try uploading at 60 fps (or 59.94, but 60 is better), letting YouTube do the framerate conversion. Some people argue this is better.

Another thing; I don't know if those x264 settings (veryslow, 3-pass, 8000 kbps) would cause YouTube's videos to judder somehow, but in general I feel YouTube gives cleaner videos with high bitrate and low complexity sources - in other words, less aggressive compression. Try this:
* single pass
* preset "Medium" or faster
* constant quality mode, quality=18
* all else default

Re: "your camera seems shaky," the thought occurs to me: try adding a logo overlay that never moves; it might break their shake detection algorithm. You should have a channel logo anyway!

It's quite large to upload and would take some time, if the Mediainfo log doesn't give enough detail let me know and I will.

2. All I do is go into Virtualdub and import the first picture of the jpeg sequence. I go to frame rate and 'change frame rate to 120 fps' and compression 'Lagarith lossless codec', then save as avi.

Here is the video file on its own:

https://dl.dropboxusercontent.com/s/s8u5agzp254o3uj/29.97UncomVideo-muxed.mp4?dl=1

7. Already did a test upload at 59.94, which was unsuccessful. It was even rendered through Premiere using h.264 instead of megui, but still no luck. Video test is here:

https://www.youtube.com/watch?v=2RQw-Y2c7bs

8. Suggested settings didn't have any effect on judder:

https://www.youtube.com/watch?v=f-aPJ9f_LIs&feature=youtu.be

9. Do you mean just like an image watermark in the corner or a title, e.g. 'Dreamtime Visions Productions' that sits in the corner?

Also worth noting that when I add '&html5=True' to the end of the video, it plays completely smoothly in html5 player on Youtube.

I'm convinced now that there is nothing wrong with your videos. It looks like Flash Player is to blame.
Google agrees:

Good to know HTML5 is an improvement.

We too have come to the same conclusion. We're offering LQ/HQ download options for users anyway as well as the Youtube stream.

Thanks for your help Raffriff, it's always encouraging to know that there are people who actually give a damn and try and solve video issues.

This is indeed due to flash player (crap).

A few monthes ago I was discussing with a gaming mate about how bad youtube video fluidity was, and that when downloading back the videos from youtube it was then played smooth by any video player (mpchc, vlc...).

He was curious (and as annoyed as me by the youtube choppyness) so he started deep testing with flash player, checking playback framerate, and comparing older versions of flash player.

The conclusion was older versions were far better, the choppyness just got worse and worse every new flash player version. He posted the result of his test on the adobe forum:
https://forums.adobe.com/thread/1380351

Unfortunately as you can see Adobe just disregarded this report... (anyone surprised ?). And today fluidity of videos played though flash player is still terrible.

My mate also started another thread about this issue on reddit:
http://www.reddit.com/r/technology/c...got_worse_and/

The only workaround so far is to use a browser plugin that will play the video with another player than flashplayer. The best ones being the FF VLC plugin and SVPtube.

Maybe some of the experts here could jump into the adobe thread and try to make things move, this would be nice (although I don't have any hope adobe would do anything seeing how many years they have left their flash player producing such a poor playback).

Yeah hopefuly we get rid of that damn flash player one day.

foxyshadis · 29th October 2014, 23:28

I'm kind of between a rock and a hard place; if I force Flash player, the video is choppy, but if I use HTML 5, the video often hangs up hard after a couple minutes of playing (even after refreshing the page). Firefox bugs, unfortunately.

Already did a test upload at 59.94, which was unsuccessful. It was even rendered through Premiere using h.264 instead of megui, but still no luck. Video test is here: https://www.youtube.com/watch?v=2RQw-Y2c7bs 8. Suggested settings didn't have any effect on judder: https://www.youtube.com/watch?v=f-aPJ9f_LIs&feature=youtu.be 9. Do you mean just like an image watermark in the corner or a title, e.g. 'Dreamtime Visions Productions' that sits in the corner? Also worth noting that when I add '&html5=True' to the end of the video, it plays completely smoothly in html5 player on Youtube. Last edited by Dreamtime Visions Product; 15th April 2014 at 01:22.*

Firefox bugs, unfortunately.
