Optimum Render Settings

[Tafflad]

I have been looking to find optimum render settings for FB/Youtube

Using Movie Studio and render format Magic AVC/AAS mp4 and the template Internet HD1080p xxx
I have a couple of Q's .... first on bit-rate

Having watched a few on-line tutorials it was saying set: variable bit rate to:Max bps 100,000,000 Avg bps 80,000.000

with added comment that Max bit-rate could be set to match source video bit-rate (setting higher gives bigger files but no extra quality) ..... how do I tell what that is ? I attach MediaInfo for one of my video clips, can you tell what is my bit-rate from that ?

By default the template is set to 24,000,000 / 12,000,000

2nd Q ...

Once Bit-rate is decided ... what fps should I use.

My source video is 60 fps, should I encode to 29.74 or as I am in Europe set to PAL of 25fps .......... some sources advise Internet is set to use 29.97 so to avoid resampling best to use that ?

I attach MediaInfo for one of my video clips, can you tell what is my bit-rate from that ?

In the Mediainfo View window, choose the "Tree" view.

OK .... now added that and can see BR is 27.7
So if it were CBR would set to 30 Mb/s
What would I set for variable ? Max & average

Gday Sport !! (long time no read )

Just a few comments. Your source video is NOT 60 fps it really is 59.94 and you leave that alone. Forget about PAL-land.


The simplest scenario would be if your editor had a setting to export at exactly the same as your source - certainly the 'Big Boy' Vegas has that. But you do not want a Constant Bit Rate since that will invariably waste resources. And upping the bitrate over what the max already is is not going to improve anything but just make the files bigger.


Others will, hopefully, chip in with more but do remember that Youtube will re-encode regardless.

The file is Max 37Mb/sec and 27Mb/sec, so use those (at 59.94, as mentioned); audio AAC at 48khz, 128Kb/sec should do.

Given the whole thing is only 9 seconds long, do a couple of runs at numbers above those to see if there is any difference.

You could also up the resolution to 2560x1440. Whack the bitrates up to 74 and 54. That will force You Tube to encode in the better VP9 video codec (otherwise, at 1920x1080, you'll get H264).

What Movie Studio version are you using? Vegas (up to ver 17) or Magix Movie Edit Pro-type Movie Studio (version 18 and above)?

9 sec clip was just for testing

I am using Movie Studio 16
I could record in 4k but frame rate drops to 30 ..... so usually capture HD at 60fps

[Alwyn]

Arr, OK. Same advice applies. It's best to send to Youtube the framerate that you captured at. YT will encode and display your video at the framerate the file you post. The Internet is not "29.97". At least YT isn't. You can check out the YT's encoding details by right-clicking on a YT video and choosing Stats for nerds.

What are you capturing? You probably should be capturing into some type of lossless format, then doing one encode to MP4 for YT (or even leave the file as lossless; YT will take "normal" lossless codecs). That way, you're only encoding once. Currently, it looks like you're capturing into MP4, then re-encoding for YT, which is not ideal.

My camera can capture at the following:

I have been using MP4 60 fps and after I edit multiple files in Vegas, Render as MP4
I had on times changed to 25p as some said as I'm in PAL region I should.
Also read that FB uses 29.97 frame rate no matter what you upload.

Sure is a lot of conflicting info out there.

[Alwyn]

Got it. "Shoot" rather than "capture". In that case, I'd just use the source file's frame rate and bit rates (off Mediainfo).

The only limiting value for bitrate will be how long it takes to upload to YT, so you may need to lower the bitrate of those 100mb/sec files to something that gives you a manageable file size. Remember that YT will encode multiple file quality/sizes, but if you are sending to family, depending on how you are doing it, you might have to drop the bit rate/file size down.

Re frame rates generally, any decent media player such as a TV, computer or phone will play any framerate you give it. DVDs had framerate rules, depending on what type it was (PAL/NTSC) but for normal files such as MP4s, no such restrictions exist. It's better to use source file's frame rate IMO.

[DB83]

Of course, since you are in PAL-land it is 'cleaner' to shoot @ 50 fps or @ 25 fps - and, as stated, render out at the shot rate.

Then you will not have any conflict with what you manual states @ 60 fps whereas the recording is reported to be @ 59.94 fps

I will try 50 vs 59.94 at Full HD and compare results

As a test I did Full HD at 59.94 and a 4k at 59.9a (and pushed up video rate)
On playback the Full Hd was smooth and clear, while the 4k was jittery .... maybe the plyer (Splash) has issue with high Bitrate.

Your camera is not recording at 60fps at 4k.
And if you convert the material recorded in 30fps to 60fps, it will not be smoother. Or it could be worse.

Second thing: check the color range your camera records in AVCHD and MP4.
My Sony records in AVCHD in the range of 16-255 and in MP4 in the range of 16-235. So the AVCHD format gives better recording quality.
