Can't render to original 16:9 resolution!

[tanguero]

My original file is 848x480 (16:9) , 30 fps, MPEG-4 (.mov). I do some minor editing and want to save the results with the same resolution. But none of the available options let me do that!

If I choose the Device > Mobile Device preset, my MPEG-4 choices are 720x480 (which is 3:2 but obviously I don't want the distortion). My next choice is 1280x720, which is 16:9 but it's silly to output over double the pixels than the source material.

If I choose Computer > Custom, which in theory lets me choose the resolution, the User-Defined frame size is greyed out in MPEG and MPEG-4 (why?) and the defaults do NOT include 848x480. I get 720x480 whether I choose 4:3 or 16:9 options, which means black bars above or on the sides, which I don't want. The User-Defined frame size is not greyed out only for .avi or .mov file types, but why do I have to be stuck with those to get undistorted output?

Seems bizarre to me. Or am I missing something? Thanks.

Unfortunately you are correct, it's impossible to custom frame sizes in the H264 codec, and VS do not have profile for 1/5 HD frame. I use WMV for that resolution, the proper 16:9 resolution is 854X480 which is good for youTube display.

** Well... you got me confused with your mov resolution. I'm using this youtube page for my uploads

having said that 854 is not conforming with with mode 16 compression so 848 might be better.

Hi

You show your vide as being 848 x 480 x 16:9, does that mean it is anamorphic and fit to widescreen.

Place the clip in the overlay track, right click the screen and Fit to Screen, does the video look distorted or in proportion.

Otherwise:-

There are options to User Define the frame sizes.

Try using Quicktime – Mpeg4 Visual

QuickTime Movie Files
24 bits, 848 x 480, 30 fps
Frame-based
MPEG 4 Visual
50% Quality, 24 Key Frame Rate
None, 8.000 KHz, 8 bits, Stereo

Not sure what your video will render to, whether you have those borders.?

Do you have a small sample you can share, maybe upload to Microsoft One Drive?

Thanks Asik1 and Lata for your responses.

Regarding the resolution 848x480, this is what my Panasonic Lumix DMC-ZS7 creates when I choose Motion JPEG > WVGA (the camera supports higher resolutions but for this video that's the one I chose). I suppose, as Asik1 suggests, that 848 is the closest to 853 that's divisible by 16 (if that is what "mode 16 compression" requires, or if that's related to a minimum block size used in this camera's encoder). You can check a 3s (3MB) sample clip from this camera here:

Sorry, I'm not sure I understand what you mean. 848x480 *is* 16:9 (within 1% anyway which no one would notice ...). Anyway, hopefully my uploaded clip will allow you to see it firsthand.

> Lata: Place the clip in the overlay track, right click the screen and Fit to Screen, does the video look distorted or in proportion.

There WAS a difference between Fit to Screen and Original Size but I think that was a function of my Project Properties, for which it had 720x480 selected.

Speaking of which, I'm confused as to what VS does with 720x480. It gives only two profile options of 720x480(4:3) or 720x480(16:9) but the last I checked 720x480 was 3:2 so why isn't that an option (my computer happens to have that as it's native screen ratio, though obviously with a higher resolution)?

> Asik1: I use WMV for that resolution, the proper 16:9 resolution is 854X480 which is good for youTube display.

Hmm, I don't see that option--can you tell me where you get this? If I choose WMV, there is nothing lower than 1280x720. If I choose Custom > Windows Media Video > Options there are numerous presets but none with 854 (or 848) x 480.

> Lata: Try using Quicktime – Mpeg4 Visual

Yes, with Quicktime and AVI I can get this resolution, but can't I have something with an .mp4 extension with a 848x480 resolution? Or are you saying that if I choose Quicktime-Mpeg4 I can just rename the .MOV to .mp4 and it's the same thing?

[asik1]

Sorry tanguero, it's a custom profile I made. Here one I modified for your needs.
Put the file from the zip into this directory \Corel VideoStudio Ultimate X7\Ulead.dat\WMV_Profiles
Open VSX7 and look for that profile in the wmv list. I set data rate as 6Mb as it more than enough for 1/5 HD (even 5mb is fine). You can edit the file in notepad but be careful, as any neglected change can make the file unrecognizable by VS.
I wasn't able to download your sample as I don't have dropbox account.

Hi

First apologies I think I was a little confused with the frames size, it is indeed 16:9, or as near as.
These are your video properties

The video is Mov using Photo Jpeg, we can replicate that format using the Custom option – QuickTime has a PhotoJpeg compression option. However the resultant file size is very large ( 3.4mb to 15 mb) I don’t know why video studio does that?

I did render the file using Mpeg4

MPEG-4 Files
24 bits, 1280 x 720, 30 fps
Frame-based
H.264 Main Profile Video: 10000 Kbps
48000 Hz, 16 Bit, Stereo
MPEG AAC Audio: 192 Kbps

That produced a similar size file, (3.3Mb) the video seemed the same quality, although a little difficult to compare with the 3 sec sample.

As the original is 16:9 there should be no problems in rendering to 1280 x 720, also 16:9.
Your video will display using the same aspect ratio.
Is there any reason why you have to use 848 x 480

4:3 and 16:9 Aspect ratio
Standard definition DVD uses 720 x 480 (NTSC) for its frame size, using a calculator you can see that those sizes are neither 4:3 or 16:9.
However the pixels are not square they are rectangular, for widescreen they are 16:9 shape.
A process called Non –Square Pixel Rendering stretches the video to its correct shape.
( Anamorphic Video ) do a google.

Video for the internet and most HD video is not anamorphic, the frame size is 16:9.
1280 x 720, standard YouTube size
1920 x 1080 generally used for HD video Bluray, Avchd.

Hi Asik

I have sent the file to your e-mail address

Hi Asik

Yes, thank you Trevor. ( I added it to my test videos directory)
I rendered the clip with the wmv profile I made and it's very acceptable. making it ~2mb

[tanguero]

Thanks guys for your helpful responses!

Dropbox: Hmm, it was a direct download link--you should have been able to download it without logging in or having an account. Anyway, glad you got it and were able to test it.

Custom Profiles: Thanks for that. Just for my information, how do you create that? If I go to Share > Computer > WMV > Create Custom Profile (+), I can create a new profile, but the Frame Size is fixed (greyed out) as are all the options, based on the base profile I choose. "Apply Preprocessing if Possible" and "Aspect Ratio" (source, 4:3, 16:9) are the only options I can change, while you could apparently change frame size, data rate and probably other things as well. How do you do that?

720x480: OK, thanks for that explanation. Didn't realize that DVD was stored always as 720x480 and always stretched one way or the other to get 4:3 or 16:9, which I guess is the 2 modes that VS supports, and you have to create a custom profile if you for whatever reason had a native square-pixel 720x480 source file and want to keep it that way.

"Is there any reason why you have to use 848 x 480 [instead of 1280x720]": Only not to be wasteful, i.e., not to have a file that's unnecessarily large with clearly no added information as the source was 848x480 (so no point in having the output file have greater resolution). Yes, I could render to 1280x720 (with a high data rate to minimize artifacts) and then use more flexible third-party conversion software (I have Digiarty's WinX converters), but of course the fewer conversions the better, both for quality reasons and of course not to add steps unnecessarily in the flow.

You don't need a dropbox account to download the file. I don't have one and was able to download without any problem.

tanguero, making profiles is something I learn few years ago when I dug deeply tweaking XP movie maker .
It's possible more easily using Microsoft Profile editor from 13 years ago.

Hi Guys

Earlier versions of Video Studio allowed access to WMV profiles with a Customise button when viewing the Templates Options – Profile tab. Enabled us to create a New WMV profile.
For some reason Corel removed that option for X6- X7?

Also there was a problem with Windows 7 maybe Vista, that did not allow us to update the contents of Windows Media Components folder. But a quick change to the Security controls fixed that, don’t think it was a problem with XP.

Not that the info helps using X7

Oh, the profiles are an OS thing and not a VS thing, and there is some kind of standard format for these profiles?? I wouldn't have guessed that, looking at the Share tab of VS and the list of profiles there! Is there some place where this sort of stuff is documented or explained?
