Camtasia Studio 8.0.3 - Data rate for Vimeo upload not high enough?

  • Answered
When uploading to Vimeo it says "This video's datarate is only 383kbps, which is lower than what we recommend and means your video might not look as nice as it should. For HD video, we suggest you use a higher datarate, typically 5000kbps."
But I can't see in Camtasia Studio 8.0.3 how I can specify a higher data rate. ???

You can create a video preset for Vimeo if you want.
Go to File menu and Produce and share...
Now select Add / Edit Preset... under the drop down list.
Select new


You can deactivate controller as it is not needed for Vimeo


And under the video settings, you can find what you are looking for (well, I suppose data rate is the bitrate but I am not sure)


EDIT: After a quick test, it doesn't match at all, the data rate seems to be something else...

Hi Mickael

Thanks for your response. I have set up my own preset for 720p MP4 rendering on Camtasia Studio. I just re-rendered w CS and re-uploaded my video again to Vimeo to confirm my settings were correct per your guidance - and to confirm settings on my preset. However, there's still a problem - it's either with CS8 or Vimeo's rendering.

Have a look at the following screen shots and tell me if you see any problems.

My video bit rate setting is at the very highest
http://www.thelonius.com.au/CamtasiaS...
I have set bit rate to max of "20000" - but this setting is not labelled so I assume it's raw bits, not kbits or kbytes...

Here's the error message I get from Vimeo:
http://www.thelonius.com.au/VimeoWarn...

On this same setting panel, I note also that there is no 25 fps setting for PAL countries like Australia - this may be a problem - I've selected "Automatic" - which I hope is correct ... not using any video - just recording a PowerPoint presentation, so it shouldn't matter ... I think ...

I have tried to use the constant bitrate mode and I have moved the Slider all theway to the right (20000). When I upload my video to vimeo it says the bitrate is much lower (around 2500) and it is never constant (fluctuates between 2500 and 2900). Any idea what is going on? Thank you in advance for your response.

The warning message from Vimeo is misleading. The data rate (a.k.a. bitrate) of a produced file is usually calculated as:

data rate (in kbps) = file size (in kilobytes) * 8 (bits/byte) / duration (sec)

A common misconception is that low data rate implies low visual quality. This is not always true. In some cases, it is possible to keep the visual quality high, and the data rate is low. In fact, that's almost always what you're striving for... the best possible visual quality at the lowest possible file size.

By default, Camtasia Studio uses Quality based compression. This is a variable bitrate encoding method where the codec attempts to maintain a certain level of visual quality, while optimizing for the smallest possible file size. The "variable bitrate" part simply means that the codec will use more bits (file size) for high motion or visually complex sections of the video, and less bits (file size) for low motion or less visually complex sections of the video. The data rate calculation above assumes a constant bitrate, which is not the case here.

The Bitrate based compression option in Camtasia Studio is similar in that it is a variable bitrate encoding. The Bitrate encoding mode results usually in a larger file size and worse visual quality, so we don't recommend it. Use the Encoding Mode = Quality, and you'll get better visual quality at smaller file sizes.

Vimeo (like YouTube) would like you to upload a video that has high visual quality. They transcode the video you upload to different sizes (which helps them target different screen sizes, tablets, phones, etc.). The data rate doesn't actually matter here, but the visual quality does matter. The problem is, visual quality is subjective and difficult to measure programmatically. One shortcut is to use the data rate (which is easily calculated from file size and duration). If it's below some arbitrary threshold, then it's possible that the video is of poor visual quality, and Vimeo issues a warning in this case.

Does this mean that your video really is low visual quality? Maybe. The best thing to do at this point would be to play the video (e.g. the MP4 file) that you uploaded in VLC or QuickTime Player. If you're satisfied that the video you're uploading is high quality, then you can safely ignore the warning from Vimeo. If you're not satisfied, then adjust the quality settings upward, and produce again. Usually, the file size will go up (sometimes by a lot) and the visual quality may improve only slightly. A larger file means you'll be waiting longer for the file to upload for what probably amounts to a small increase in visual quality.

So that's the real tradeoff here... you can improve the visual quality slightly, but you'll get a larger file, and you'll have to wait longer for it to upload. It's up to you to decide what visual quality is "good enough" and how long you're willing to wait for it.

Hope this helps.

Dave's answer was helpful (Thanks Dave!) - but only "sort of" helpful. I think this is a problem that is somehow created by Camtasia. Why do I think this? Because when I upload .mp4 files that I have created using Vegas Pro, I do not get this message from Vimeo.

Camtasia is doing some kind of video compression (?) when creating the resulting .mp4 file that Vimeo isn't happy with.

I would prefer that Camtasia give me more options for controlling the creation of the final output .mp4 files. It seems to be over-simplifying these settings. That's fine for some users, but I'd like to have more visibility of settings options for output.

Jon,

As I tried to explain, the warning message from Vimeo can be safely ignored if the visual quality of the video you're uploading is good. Vimeo is applying a simple test, and because the bitrate (a.k.a. file size / duration) is lower than some threshold, they conclude that the file *might* be low visual quality, which is a problem they cannot fix by transcoding your video.

But here's the important part... YOU can determine whether or not the video you're uploading is high visual quality BETTER than Vimeo can. And you should. Before uploading your video to Vimeo, view it at 100% scale in an MP4 player. Maybe try a couple different MP4 players to be sure. If you've produced with one of the presets in Camtasia Studio 8 that includes the Flash/HTML5 player, the video should play automatically in the browser. You could also play the MP4 file in VLC, or QuickTime, or Windows Media Player on Windows 7 or later. The point is... you want to make sure the file you're uploading to Vimeo is high visual quality. If it is, then you can rest assured that you've done your job.

If you're not getting this message with videos you export from Vegas Pro, it's probably because it does a worse job compressing the video, meaning you're uploading a larger file. Vimeo sees the larger file, which exceeds their arbitrary threshold, and the warning is not issued.

If you want a larger file from Camtasia Studio, in order to suppress the warning message from Vimeo, produce with Custom settings to MP4, and on the Video settings tab, adjust the quality slider to 90%, as shown here. This will give you a larger file, as compared to the default settings in Camtasia Studio, and this is more likely to suppress the warning. I doubt you'll see much improvement in visual quality. But you're certainly welcome to try it for yourself, if the warning worries you.

Hope this helps.

The problem I am having, is that I try the various mp4 players and the video looks grand!, but once I upload to Vimeo and YouTube (even with the data rate warning) the text in my video (which is a screen-share) video is much cloudy compared to viewing it on mp4 player. Any ideas? I guess I am not too concerned with the Vimeo warning, but looking for more guidance on how to adjust screen res, edit res and produce res for screen-recorded videos where text is essential

This is because you're not watching the same video you uploaded when you view it on Vimeo or YouTube. Vimeo and YouTube are transcoding the video you upload at various sizes, in order to 1) save bandwidth and 2) target small screen devices (phones, tablets, etc). The scaling of your video to smaller sizes is what degrades the quality of your text the most.

See if you can find a higher quality version of your video on the site. For YouTube, you can change the quality to access a 720p version, for example, provided that you've uploaded something 720p or larger to YouTube, and you've waited long enough for YouTube to "process" (a.k.a. transcode) your video at the larger size. The first video that shows up is generally the lowest quality video, because it's the fastest for them to create the small dimension version of your video first, and then the larger dimension versions will show up later, as they become available.

Hope this helps.

Dave O., yes you are correct. Once I looked at the "HD" (720p) version of the video all the text and resolution was perfect!

Thanks for the clarification on this.

Hi Dave,

I hope this thread is still active. I've been having the same problem with both Vimeo and YouTube. I've uploaded lots of videos to YouTube with no problem but for some reason now both sites won't transcode the video to the proper size (I guess).

I've attached some screenshots to show the process I took to create and upload the video to both Vimeo and YouTube.



This is what the video looks like when I play it on my computer.



Here is the Vimeo Upload




Here is the YouTube upload.






I know it's a lot of pics but I just wanted to be thorough.

What the heck am I doing wrong???

Hi,

In Camtasia Studio 8.6 we added Vimeo output directly from Camtasia Studio.  The settings it uses to produce are stored in a file called Vimeo.xml which is a Camtasia Studio production preset.  However since this file isn't stored in your typical production preset directory but rather in your install directory you will need administrative rights to edit/replace this file.  This file is typically found at the following location: C:\Program Files (x86)\TechSmith\Camtasia Studio 8\Media\Studio\Images\Vimeo.xml

As a Camtasia Studio production preset it means you can replace it with one of your own if you would like.  This hasn't been tested!!!  But you should be able to replace the file with a production preset with the settings you desire.

The settings used are:
MP4 output at your editing dimensions,
Baseline profile,
Bitrate average of 800kbps
Audio bitrate of 128kbps

I hope this helps!

That's a great tip about changing the pre-set.
I'm guessing 800kbps was a typo and it's actually 8000?

Either way, the number is probably to low for any video below 720p. Definitely to low for 1080p.
 I think TechSmith should revise the .xml file. There should be outputs based on different resolutions. Just like basic mp4 outputs without a controller.
 Revising .xml files is a daunting task for a lot of people.   

Here's  Vimeo's  recommendations.  

Bit rate

Bit rate (also known as data rate) controls the visual quality of the video and its file size. The rate is most often measured in kilobits per seconds (kbit/s). If your video editing software gives you the option, choose a “variable” bit rate and set the target to at least 2,000 kbit/s for standard definition (SD) video; 5,000 kbit/s for 720p HD video; or 10,000 kbit/s for 1080p HD video.

Quality Bitrate (kbit/s)
SD 2,000 – 5,000
720p 5,000 – 10,000
1080p 10,000 – 20,000
Codec: AAC-LC (Advanced Audio Codec)

For best results, we recommend using AAC-LC (low complexity) for the audio codec.

Data rate: 320 kbit/s

For best results, encode your audio at constant rate of 320 kbit/s.


Sample rate: 48 kHz

For best results, set your audio sample rate to 48 kHz. If your working setting is already less than or equal to 48 kHz, leave it as is.

Regards, Joe

I have the same issue and I don't have the knowledge to deal with it. Please could Camtasia work together with Vimeo so the videos produced actually fit the Vimeo requirements.

nehora,

What you want to do is a produce your video as a Custom Production.

I've uploaded many videos to Vimeo. I've outlined the important settings to use. You can disregard the other settings and produce a High Quality video.

 It's pretty simple to do if you follow the steps in the Image Below, Click on the image to enlarge it.

Thanks Joel This is super kind of you and very helpful indeed.
I followed the directions and uploaded the video which is a 1280x 720p. I chose a bitrate in the middle of 7500. The video looks OK but maybe not as sharp as it could, however the vimeo site said
  • This video contains unknown color properties, and may look incorrect on Vimeo as a result. If it looks weird, try re-encoding your video with explicit color properties.
  • This video’s bit rate is only 1469 kbit/s, which is lower than what we recommend for H.264 video. Your video might not look as nice as it should. For 1280x720 video, we recommend a data rate of at least 5000 kbit/s. Learn more about our recommended compression settings.
That iwasvery strange.  I raised the bitrate to 10500, but it didn't help. So aftermessing around a bit I put the bitrate back to quality. Vimeo seemed to like that!
The other settings I left the way you suggested and now it works really well. Thanks so much for you great help!
