Changing bitrate and FPS

I have googled this and to no avail.

BITRATE PROBLEM

Where can I see what the current bitrate is for my video project? I have to produce it using H.264, 30 FPS, 16:9, 1280X720, and 3,000 kbits.



I can see where to select every setting except for making sure I have 3,000 kbits. Where do I go to check to see what the data rate is and change it if need be?

FPS PROBLEM

Also, my settings has 30 FPS selected, but every time I drop a video file, a warning message comes up that my video file is in 30 FPS, but my settins are 29...which deosn't make sense because my settings show 30.

Hi dsrt16 from Arizona -

Firstly, your project doesn't have a bitrate until you produce the video. Each clip in your project has a bitrate, which can be checked by right click > Properties.

When you go to the Produce module, you can make the selections you want - H.264, M2TS/MP4/MKV, 1280x720, 3MBps - That's the only place you set the output bitrate.

With frame rate (fps) the difference between 30fps & 29.97fps is the use of "drop frame timecode" - you can set that in preferences.

I wouldn't worry too much about the frame rate alert. You can turn that off under "Confirmations" in Preferences.

Cheers - Tony

Thanks!



When I go into produce, I see where to select H.264 and 1280X720, but I don't see anything about the bitrate. I select this setting after selecting H.264 and choosing MP4: 1280X 720/30 (16MBPS).



That is all I see to select. Sorry, I really am very ignorant on this terminology...bit rate means nothing to me. I was just told that the video I sent in for review on a teaching forum was a bit pixelated, and so it needed to follow these settings.



H.264, 30 FPS, 3,000 kbits, 16:9, and 1280X720. THe only one I don't know how to do is the 3,000 kbits..

Oh, and when I right click the clips, it says they are 192 kbs, which is a long way from the 3,000 this company wants.

Oh I just went into custom profile, and it allowed me to enter in 3,000 for the bit rate, so hopefully this works.



Thanks for guiding me in the right direction.

Good work dsrt16!

That 192Kbps sounds like it might be the audio bitrate.



What's the original source material? If the video bitrate or resolution is very low, that would account for some fuzziness.

Ah yes. The video one says 17.11 MBPS. So hopefully, that was ok when I changed it to 3,000 kbits during production stage.

Your original video says 17.11 MBPS = 17.11 MegaBitsPerSecond. you are producing it is 3,000 kbits which is 3 Megabitspersecond. You are taking a 17 Megabitspersecond video and reducing it to 3 megabitspersecond.

3 Megabitspersecond is very bad quality for a High definition video. Carl312: Windows 10 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1GB,240GB SSD,two 1TB HDs.

Hmmm...All I know is that Udemy requires the following specs to approve your videos:



H.264

30 FPS

3,000 Kbits

16:9

and 1280X720



My video was slightly blurry (according to them--it looked fine to me, but what do I know), and they said to make sure I had those specs. But you are saying 3,000 kbits is bad quality? So should I do some other settings to get approved, and they will never know it wasn't 3,000 kbits. They just don't like the "slightly blurry" look.

I would guess the 3,000 kbits is a minimum bitrate. Depending on what their use is for the video you could produce H.264 1280x720 29.97 fps at 6,000 Kbps. That would improve the quality of the video and the file size would be much larger.

As to the blurry video, that could because the original video was not clear and in focus. Carl312: Windows 10 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1GB,240GB SSD,two 1TB HDs.
