Need Help with Rendering profile for constant 29.97 fps

Need Help with Rendering profile for constant 29.97 fps

Postby meverett » Sun May 05, 2019 6:51 pm

I have a time crisis! We have a broadcast launch set for Monday, May 6 1 pm EST and this is Sunday, May 5! I cannot seem to get my file to render correctly in the profile specified by the network.

I have Corel VS Ultimate 2019, Win10 and have created an edited video file to be uploaded and broadcast on a digital HD TV network.
Here are the specs they require: H.264/AVC, 1920x1080, MOV or MP$, 1080i or 720p HD, 29.97fps CONSTANT, Audio @ 48kHz; They can receive MP4 or MOV

I have rendered the file using the MPEG4 setting with those specs, and they got back to me that it must be CONSTANT not VARIABLE FPS.
So, I tried using the H.264/AVC setting with those same specs selected, again failed to be recognized by the station as correct.
And, on my third try, I used Handbrake to encode the rendered mp4 file as constant. NONE of these files are recognized by the station's software as fitting the profile for broadcast.

Based on support from Corel, I also tried renaming the extension to MP4 via the FTP feed and that didn't work either.

I contacted Corel support by phone and she told me to use the "Same as Project Settings" setting to render and that somehow would produce CONSTANT FPS not variable. ??? Trying that right now but not expecting that to be the fix really.

I desperately need some help from someone who actually does video editing work and understands the question, the specs, and can steer me correctly as each render takes hours that I do not have to keep trying this or that hoping it works. The network contact uses Premiere Pro so has not been able to help from that end. And unfortunately, all my 10 years experience is with Corel VSP and just for Vimeo, YouTube, etc, never for use for a broadcast network show, so I don't know how to edit in Adobe PP. Thanks so much for any help you can add!

Are you absolutely sure that it is the FRAME rate they want constant, and not the BITRATE? I ask since Video Studio has great difficulty with variable frame rates. The latter have only appeared recently, mostly with certain smartphones which film with variable frame rates. For the most part, VS just refuses to accept them, or if it does, you can't do much with them.

When VS says it is going to use 29.97 fps, that frame rate IS constant throughout... So I don't know what your TV station is on about if indeed they are talking about frame rates.

On the other hand, bitrates (also called data rates) are the usual aspect of video where "variable" and "constant" are used. So that is why I wanted to know what the TV station actually says.

Thank you for replying, and I apologize for my ignorance in this situation. This is a copy and paste of what they told me: "I just looked at your program and it is incorrect formatting. The frames per second should be set to constant frame rate @ 29.97 FPS. It is currently set to variable frame rate."

I did just re-render selecting "same as project" settings and uploaded but haven't heard back yet.

One more thought - I am certainly willing to work on the Bitrate being constant if that is the problem instead, but didn't see anywhere I could change anything from variable to constant :(even looking in the edit preset profile settings box.)

My temporary fix was to download Adobe Premiere Pro, pull in the mp4 rendered with CVSUltimate 2019 and render it again with the constant bitrate once I found it in the settings of the Adobe presets. Super disappointed in phone Corel Support and the product after using it for ten plus years upgrading to the new versions every time! just to have to use another product in order to render the project with a very universal and widely used HDV setting. Was totally my bad on the terminology and for not knowing the difference between the fps and the bitrate - I am so grateful for that instruction from this boards admin! SOOOO if anyone does have the location where that setting can be found in CVS2019 I would LOVE it. I watched instruction videos on the Corel site about working with UHD videos, which revealed some of the settings in project preferences that were helpful, but unfortunately, the "variable" data rate was greyed out and could not be changed. Thanks for any input if you come across this post. I'm so familiar with CVS I hate to switch entirely to APP but may be necessary. ;(

Yes, I see the greyed out "Variable" too. I seem to recall that at one time we could change that, so maybe its gone... or else my memory is faulty. Maybe it applied to mpeg-2 in DVD days... In any case, I am surprised that the TV station insists on Constant data rate. It will give nominally better quality, yes, but a lot of what we see uses variable data rates too.

Anyway, now that you have a video with the correct type of data rate, and you intend to make more videos for this TV station there is a way to do it. If you go to Settings and choose Movie Profile Manager, it will bring up a dialogue box. Choose MPEG-4. Then click on the Add button. Another small box will appear with a box for File Path and then Profile Name. Insert a memorable name here. Then in the File Path line, click on the "..." button and navigate to where your correct video is stored. (It could be useful to make a very small cut of that file, and use that here.) Then click OK. Then, in future, when you want to make another video with those exact properties, including constant data rate, you should see your memorable name at the bottom of the format list under Custom. Choose that, of course.

Just one note of warning, though. Never try to change the properties of this format entry. Otherwise it will revert to some vanilla version of the format, and its properties will be lost. That's why I suggested you make a small file from the original, and use that as the target. That way you can later move the main file wherever you want, and still have the target in place, not taking up too much room.

You, sir, are the best! That makes perfect sense and I will set that up just as described. Especially using the cut down version as a placeholder for the format. Thank you for your time and expertise!
