Video Resolution Loss When Importing to VideoStudio Pro 2018

Hello everyone,

I've used Ice Cream Screen Recorder to create a video which I want to edit in VideoStudio Pro 2018, but I see a large loss of resolution when I import the file into VideoStudio. A screenshot of the original video is below:

A screenshot of the video in VideoStudio is below:

In the original video I can clearly read the text in Excel and on web pages I visited, but in VideoStudio the text looks blurry.

The original video properties are:

Resolution: 1600 x 900 (same as the monitor I recorded)
Format: webM
codec: VP8
size: 118 MB
frame rate: 30 fps
Data rate: 592 KBps
Audio type: Ogg Vorbis Audio, 44.1 kHz, 16 bit, stereo

I've tried varying the project properties including:

MPEG-4 Files
24 bits, 1920 x 1080, 25 fps
Frame-based
H.264 Main Profile Video: 8000 Kbps, 16:9
44100 Hz, 16 Bit, Stereo
MPEG AAC Audio: 128 Kbps

I also tried upping it to 100 fps and 30 Mbps which didn't seem to make a difference. I want to share the video with a third party which could either be by using WeTransfer or putting it on YouTube/Vimeo so I'm flexible on the output type as long as the resolution stays the same as what I recorded.

Please help! Any suggestions are appreciated.

Alasdair

Try letting VS determine the project properties.

tletter -- the problem with your suggested solution is that the original video is in WebM format which, as you know, is a successor format to Flash .flv. And if you insert a WebM clip as first clip in a New Project, you will not get that message.

Alasdair2000 recorded his video using Ice Cream Screen Recorder, and I suspect WebM is the first, or default, format it records to. And I think using it here has been a mistake in terms of later editing or conversion by Video Studio. The main problem is the frame size (1600 x 900) which is not a standard video frame size. VS has used a frame size of 1920 x 1080, which is of course a standard full HD frame size. But expanding the original frame size will of itself have introduced some distortion in the re-rendered clip.

What I think Alasdair2000 should have done was to set his Ice Cream Screen Recorder not to record in WebM, but instead chosen one of its other possible formats: MP4, AVI or MOV. And MP4 would be my choice here, making sure the frame size it used was one of the standard sizes e.g. 1280 x 720 or 1920 x 1080. Video Studio would not have a problem with such video, and the question tletter referred to in Preferences, would be asked by Video Studio if Project Properties should match those of the video. Then when editing has been done and you go to Share to render the project, you could choose Same As Project Settings or even Same As First Clip, and get a new video with exactly the same properties as the original. And importantly, quality would thus be totally preserved.

Moreover, if Alasdair2000 then wanted to share his video with someone else via Vimeo or You Tube, if his video was in WebM format, then it would be converted by those services to their preferred properties and format, and loss of quality would almost undoubtedly ensue. Making the original video in MP4, editing and re-rendering it as MP4, on the other hand, would preserve quality and be accepted pretty much as is by You Tube, again with little to no loss in quality.
